Good day everybody and welcome! I’m Dr. Michael Greger, coming to you reside from my treadmill for our very first CME-approved webinar, persevering with medical training for docs and different medical professionals. As such, I’m proud to declare I’ve no related monetary relationships with ineligible firms to reveal. (That type of declaration assertion is critical given an extended checkered previous of Massive Pharma and medical instrument firms secretly propping up paid shills to push their merchandise—so now they simply non-secretly prop up paid shills to push their merchandise, however a minimum of it’s a bit of tougher for them to cover, although). However no business bias right here.
Earlier than I cowl the professionals and cons of medication used to deal with osteoporosis, I’m going to begin us off at the moment masking medication that will trigger it.
(video begins – Acid Reflux Drugs Could Trigger Osteoporosis)
Almost 1 in 5 adults on the earth could have osteoporosis. That’s tons of of thousands and thousands of individuals. The phrase “osteo-porosis” actually means porous bone. Now, most of our bone is definitely porous to start with. That is what regular bone seems like inside, however this, is osteoporosis.
Bone mineral density is taken into account to be the usual measure for the prognosis of osteoporosis. Though the bone density cut-off for an osteoporosis prognosis is type of arbitrary, utilizing the usual definition, osteoporosis could have an effect on about 1 in 10 girls by age 60, 2 in 10 by age 70, 4 in 10 by age 80, and 6 or 7 out of 10 by age 90. Osteoporosis is often considered a illness of ladies, however one third of hip fractures happen in males. The lifetime threat for osteoporotic fractures (for 50-year-old white men and women) are 40% and 13%, respectively.
The excellent news, is that osteoporosis needn’t happen. Based mostly on a research of the biggest twin registry on the earth, lower than 30% of osteoporotic fracture threat is heritable, main the researchers to conclude, “Prevention of fractures [even] within the oldest aged ought to give attention to life-style interventions.” That is according to the large variation in hip fracture charges world wide, with the incidence of hip fracture various 10-fold, and even 100-fold between nations, suggesting that extreme bone loss is not only an inevitable-consequence-of-aging.
The US Preventive Companies Job Power, an impartial scientific panel that units evidence-based, medical prevention pointers, recommends osteoporosis screening (reminiscent of a DXA bone mineral density scan) for all girls aged 65 years and older and doubtlessly beginning even sooner than 65 for ladies at elevated threat (reminiscent of having a parental historical past of hip fracture, being a smoker or an extreme alcohol client, or having low physique weight). What must you do if you happen to’re identified, or extra importantly, what must you do to by no means be identified? Earlier than exploring the medication on providing to deal with osteoporosis, there are some medication that will trigger it, so let’s begin there.
Abdomen acid-blocking “proton pump inhibitor” medication, so-called PPIs—with model names like Prilosec, Prevacid, Nexium, Protonix, and AcipHex—are among the many hottest medication on the earth, raking in billions of {dollars} a 12 months…. However then, in 2006, two observational research out of Europe steered an affiliation between consumption of this class of medication and elevated threat of hip fracture, and by 2010, the rising proof pressured the US Meals and Drug Administration to situation a security alert implicating PPI use with fractures of the hip, wrist, and backbone. By now, there’ve been dozens such research involving greater than two million people who, total, present increased hip fracture charges, amongst each long- and short-term customers… in any respect, dose, ranges….
The irony is that most individuals taking these medication shouldn’t even be on them within the first place. These PPIs are solely FDA-approved for 10 days of use for the therapy of H. pylori, as much as 2 weeks for heartburn, as much as 8 weeks for acid reflux disease illness, and for two to six months for ulcers. But, in a group survey, most customers remained on these medication for greater than a 12 months, and greater than 60% of sufferers have been taking them for inappropriate causes, (usually wrongly prescribed for quote-unquote “indigestion,” as an illustration).
Calls to cease this huge overuse from regulatory authorities have fallen on deaf physician ears. And now that they’re accessible over-the-counter, the issue of overuse could have gotten even worse. They are often laborious to cease taking since many sufferers expertise withdrawal signs that may final for weeks. In truth, if you happen to take regular, wholesome volunteers with none signs and put them on these medication for 2 months after which covertly swap them to a placebo with out their data, hastily, they’ll develop acid-related signs, such heartburn or acid regurgitation, so ending up worse off than they have been before-they-even-started-taking-the-drugs.
Along with bone fractures, this class of medication has additionally been linked to elevated threat of different potential long-term hostile results… reminiscent of pneumonia… intestinal infections… kidney failure… abdomen most cancers… and heart problems. (In truth, the blood vessel results may clarify the case report “Abrupt-Onset, Profound Erectile Dysfunction in a Wholesome Younger Man After Initiating Over-the-Counter Prilosec.”) Oh, and in addition, untimely loss of life….
There are people with situations like Zollinjer-Ellison syndrome—stricken with tumors that trigger extra abdomen acid secretion—for whom the chance versus advantage of long-term use could also be acceptable, however that’s a far cry from the 100 million PPIs prescribed yearly in the USA alone.
To take care of acid reflux disease with out medication, suggestions embrace weight reduction, smoking cessation, avoiding fatty meals…. particularly inside 2 to three hours of bedtime…. elevated fiber consumption, and, total, a extra plant-based weight-reduction plan as a result of nonvegetarianism is related to twice the chances of acid reflux-induced irritation.
Different lessons of medication which were related to hip fracture threat embrace antidepressants, anti-Parkinson’s medication, antipsychotics, anti-anxiety medication, oral corticosteroids, and the opposite main class of heartburn medication, the H2 blockers, reminiscent of Pepcid, Zantac, Tagamet, and Axid.

OK, so extreme bone loss is not only an inevitable-consequence-of-aging, and one of many issues we will do to decrease our threat and that of our sufferers is to have in mind the potential skeletal unwanted effects of the medication we take and prescribe.
What concerning the medication prescribed to deal with osteoporosis? First let me tackle efficacy:
(video begins – How Effectively Do Medicines Like Fosamax Work to Deal with Osteoporosis?)
Drug remedy for osteoporosis is beneficial for these 50 and older with a historical past of previous hip or backbone fractures, these with hip or backbone “T-scores” of unfavorable 2.5 or much less, and postmenopausal girls or males 50 and older who don’t make that cut-off—however, have an estimated 20% or increased threat of a significant osteoporotic fracture over the following decade, or an estimated 3% or higher threat of hip fracture, particularly.
A T-score is a measure of how dense your bones are in comparison with a 30-year-old white lady. Since that’s the usual, and we are inclined to lose bone as we age, you may be labeled as having osteoporosis even in case you have fully regular bone density in your age. After all, simply because your bone density could also be regular doesn’t imply it’s essentially optimum, which is why the Nationwide Osteoporosis Basis set out these pointers for drug therapy. Although, another excuse, maybe, is as a result of it will get substantial funding from the drug business, that rakes in actually billions of {dollars} in income from osteoporosis medication. What, does the science say?
The first drug class used to deal with osteoporosis is the bisphosphonates, bought as such manufacturers as Fosamax, Actonel, Boniva, and Reclast. They’re handiest at decreasing vertebral fractures, slicing the chance in postmenopausal girls from 2.8% right down to 1.4%. That’s a relative threat discount of fifty%, however an absolute threat discount of only one.4%, that means you’d should deal with 71 girls to forestall only one lady from getting a vertebral fracture.
Sadly, the prognosis of vertebral fracture is type of wishy-washy. Relying on the way you outline the adjustments on x-ray, the prevalence of vertebral fractures can fluctuate by as a lot as 3% to 90% in the identical aged inhabitants—virtually none, to virtually all. They’re additionally poorly predictive of again ache or incapacity. Vertebral fractures can actually result in again ache and diminished bodily perform, however solely a couple of third are symptomatic—in any respect. Probably the most dangerous fractures, are hip fractures.
Regardless of many of the medical trials for osteoporosis therapy being funded by the drug firms themselves, no major prevention profit from bisphosphonates has been discovered for hip fractures. In different phrases, taking these medication has not been convincingly proven to forestall fracturing your hip within the first place. Nevertheless, having a previous fracture doubles your threat of breaking one other bone, so, for these at excessive threat, bisphosphonate medication could lower the chances of hip fracture by 25%, although absolutely the threat discount is, once more, solely about 1%. It might take treating 91 folks for 3 years to forestall one hip fracture.
An overconfidence within the energy of capsules and procedures for illness prevention could also be one of many causes docs and sufferers alike could undervalue weight-reduction plan and life-style approaches. On this research, sufferers have been requested to estimate the variety of fractures or deaths prevented in a bunch of 5,000 sufferers present process every drug intervention over a interval of 10 years. The overwhelming majority of individuals tended to wildly overestimate the flexibility of mammograms and colonoscopies to forestall most cancers deaths, the facility of medication like Fosamax to forestall hip fractures, and medicines like Lipitor to forestall deadly coronary heart assaults. No surprise most individuals proceed to depend on medication to avoid wasting them! However the soiled little secret is, that most individuals stated they wouldn’t be prepared to take many of those medication in the event that they knew how little profit these merchandise truly provided.
In a survey of these present process bone density scans, the typical five-year fracture threat that will encourage most members to think about preventative treatment was 50 to 60%—a lot increased than their precise threat. Most sufferers need to be informed the reality. They need to be informed what the possibilities are that the medication will truly profit them, however there’s a stress between the affected person’s proper to know and the probably discount of their willingness to take the drug in the event that they knew the reality.
Within the bone density scan survey, members significantly overestimated their very own private threat for hip fracture, considering it was round 19% over the subsequent 5 years, which is greater than ten instances increased than their precise threat, of 1.4%. Quite than disabusing them of this overestimate, some recommend physicians ought to do the other: Stoke fears in sufferers who “refuse to adjust to treatment suggestions” by rising their “perceived susceptibility to fragility fractures” in addition to their “perceived severity of affected by a fragility fracture.” Since emotion may be extra motivating than cause, and anecdotal proof may be simpler than proof proof, a “graphic situation of struggling and incapacitation after a hip fracture will improve emotional notion of this menace.”
However hip fractures can certainly be devastating, and are related to a major threat of ensuing loss of life. So, what about the entire lives these medication have to be saving? Effectively, solely a couple of quarter of the deaths following fractures could also be attributable to the fracture itself, so many of the mortality threat could be a consequence of the comorbidities—that’s, the opposite illnesses and poor well being standing of people that are inclined to fracture their hips. So, they might have died anyway in that very same time-frame even when they hadn’t damaged any bones. This will assist clarify why there are, no saved lives. Osteoporosis drug remedies, significantly bisphosphonates, fail to considerably scale back total mortality.
(video ends)
OK, so the efficacy of the first drug class used to deal with osteoporosis is so slight on a person foundation, that the majority sufferers, if actually absolutely knowledgeable, probably wouldn’t take them. And that’s earlier than even speaking concerning the unwanted effects, which I flip to subsequent:
(video begins – Facet Results of Osteoporosis Drugs Like Fosamax, Boniva, and Reclast)
Potential lack of efficacy… shouldn’t be the one cause why most individuals prescribed bisphosphonate medication for osteoporosis like Fosamax, Actonel, Boniva, or Reclast could cease taking them inside a 12 months. There are two uncommon however devastating unwanted effects— osteonecrosis of the jaw, and atypical femur fractures—that contributed to round a 50% drop in using this class of medication once they got here to mild. The New York Instances article noting the decline defined the reasoning: “Stories of the medication’ inflicting jawbones to rot and thighbones to snap in two have shaken many osteoporosis sufferers a lot, that they are saying they’d relatively take their probabilities with the illness.”
The jaw-rot syndrome that stops many from initiating therapy for concern of “their jaw falling off” can severely impression many facets of high quality of life however, is exceedingly uncommon, affecting at most 1 in a thousand sufferers handled for osteoporosis. Atypical femur fractures can happen extra steadily, although, as many as 1 in 300 customers handled for 3 years. They’re referred to as “atypical” as a result of they happen not after a fall or trauma, however simply throughout routine actions, like strolling, twisting on the waist and even simply standing nonetheless. Your femur, your thigh bone, the most important bone in your physique—simply breaks in half. Too merciless an irony from a drug that’s supposed to guard your bones. That is what it seems like on x-ray. Ouch.
Bisphosphonates work by inhibiting the motion of a sort of bone cell referred to as osteoclasts. Your complete skeleton is continually being transformed with bone added in some spots and brought away in others to adapt to altering calls for. The cells which can be frequently laying down new bone are referred to as osteoblasts, and those that chisel away outdated bone are the osteoclasts. It is sensible, then, that curbing the ‘clasts would stop bone loss. However by decreasing the energetic transforming course of, bisphosphonates may “freeze” the skeleton, permitting for the buildup of microcracks over time, leading to stress fractures. Different osteoporosis medication like den-o-sumab (bought, as “Prolia”) stop the brand new formation of osteoclasts within the first place, and have been stricken by the identical sorts of uncommon however disturbing unwanted effects.
As with something in life, all of it comes right down to dangers versus advantages. What number of hip fractures are prevented for each femur that snaps? It will depend on your race, and the way lengthy you’re on these medication. After 5 years in White girls, 36 hip fractures are prevented for each atypical femur fracture. Hispanic girls solely get half the profit, with about 18 to 1, and for Asian girls it’s solely about 5 hip fractures prevented for each femur fracture prompted. (The research claims it didn’t accrue sufficient information on Black girls.) At ten years of drug publicity, the ratios worsen, 16:1 for White girls, 5:1 for Hispanic girls, and solely about 1.5:1 for Asian girls, that means that the devastating fractures prevented and prompted in Asian girls are almost comparable.
A nationwide survey of resident physicians discovered that data concerning osteoporosis prognosis and therapy was poor, with a very hanging lack of know-how concerning the 2 severe drug side-effects. The excellent news is, that after stopping the medication, the chance of femur fracture quickly drops by 70% inside a 12 months, resulting in the suggestion {that a} drug “vacation” be thought of after a number of years on the drug to assist mediate the chance.
(video ends)
How loopy is the atypical femur fracture information? I simply can’t recover from the irony of all of it. OK, so between the shortage of ample efficacy and these uncommon however devastating unwanted effects, what can we do personally, and the way can we counsel our sufferers to guard their skeletons? Earlier than we get to life-style approaches, let me cowl calcium and vitamin D dietary supplements.
(video begins – Are Calcium Dietary supplements Secure?)
In 12 quick years, authorities panels have gone from suggesting widespread calcium supplementation could also be mandatory to guard our bones to “Do Not Complement”. What occurred? It began with a 2008 research in New Zealand. Quick-term research had confirmed that calcium supplementation could drop blood pressures by a couple of level. Although the impact seems to be transient, disappearing after a number of months, it’s higher than nothing. And extra calcium within the intestine could cause fats malabsorption, by forming cleaning soap fats, decreasing saturated fats absorption and rising fecal saturated fats content material. And, certainly, if you happen to take a pair Tums alongside together with your half bucket of KFC, as much as twice as a lot fats would find yourself in your stool, and with much less saturated fats absorbed in your system, your ldl cholesterol may drop. So, the New Zealand researchers have been anticipating to decrease coronary heart assault charges by giving girls calcium dietary supplements. To their shock, there seemed to be extra coronary heart assaults within the calcium complement group.
Was this only a fluke? All eyes turned to the Girls’s Well being Initiative, the biggest and longest randomized managed trial of calcium supplementation. The identify could sound acquainted—that’s the research that uncovered how harmful hormone substitute remedy was. Would it not do the identical for calcium dietary supplements? The Girls’s Well being Initiative reported no hostile results. Nevertheless, the vast majority of the members have been already taking calcium dietary supplements earlier than the research began; so, successfully the research was simply evaluating increased versus decrease dose calcium supplementation, not supplementation or no supplementation. However what if you happen to return and simply see what occurred to the ladies who began out not taking dietary supplements after which have been randomized to the complement group? Those that began calcium dietary supplements suffered considerably extra coronary heart assaults or strokes. Thus, excessive dose or low dose, any calcium supplementation appeared to extend heart problems threat.
Researchers went again, digging by way of different trial information for coronary heart assault and stroke charges in girls randomized to calcium dietary supplements with or with out vitamin D added, and confirmed the hazard and many of the inhabitants research agreed—customers of calcium dietary supplements tended to have elevated charges of coronary heart illness, stroke, and loss of life.
The complement business was not joyful, accusing researchers of relying partly on self-reported information—like they simply ask if folks had a coronary heart assault or not relatively than verifying it. And certainly long-term calcium supplementation prompted all types of gastrointestinal misery together with twice the chance of being hospitalized with acute signs that will have been confused with a coronary heart assault. However no, the elevated threat was seen constantly throughout the trials whether or not the center assaults have been verified or not.
OK, however why do calcium dietary supplements improve coronary heart assault threat, however not calcium you get in your weight-reduction plan? Maybe as a result of once you take calcium capsules, you get a spike of calcium in your bloodstream that you simply don’t get simply consuming calcium wealthy meals. Inside hours of taking supplemental calcium, the calcium ranges within the blood shoot up and may keep up so long as eight hours. This evidently produces what’s referred to as a hypercoagulable state, your blood clots extra simply, which may improve the chance of clots within the coronary heart or mind. And, certainly, increased calcium blood ranges are tied to increased coronary heart assault and stroke charges. So, the mechanism could also be calcium dietary supplements result in unnaturally massive, fast, and sustained calcium ranges within the blood, which might have quite a lot of doubtlessly problematic results.
Calcium dietary supplements have been broadly embraced on the grounds that they’re a pure and, due to this fact, secure means of stopping osteoporotic fractures. However, it’s now changing into clear that taking calcium in a single or two each day doses is not pure, in that it doesn’t reproduce the identical metabolic results as calcium in meals. And moreover, the proof can be changing into steadily stronger that calcium supplementation is probably not secure. That’s why most organizations offering recommendation concerning bone well being now advocate that people ought to receive their calcium requirement from weight-reduction plan rather than dietary supplements. But when we will’t attain it by way of weight-reduction plan alone, would the advantages to the bones outweigh the dangers to the center?
(video ends)
We nonetheless must get sufficient calcium, nevertheless it must be by way of meals, as nature supposed, not by way of tums. Let’s flip from calcium complement security, to efficacy
(video begins — Are Calcium Dietary supplements Efficient?)
There was an assumption for many years that as a pure aspect, calcium dietary supplements should intrinsically be secure, however calcium supplementation is neither pure nor risk-free. However, the identical could possibly be stated for each treatment on the planet. But, docs proceed to put in writing billions of prescriptions for medication yearly as a result of the hope a minimum of is that the advantages outweigh the dangers. So, what about the advantages of calcium dietary supplements. Sure, coronary heart assaults and strokes may be devastating, however so can hip fractures. The danger of dying shoots up within the months following a hip fracture. About one in 5 girls don’t final a 12 months after a hip fracture, and it might be even worse for males, on common apparently slicing one’s lifespan quick by 4 or 5 years. And, sadly these dismal statistics don’t appear to be getting a lot better.
So, even when calcium dietary supplements prompted a number of coronary heart assaults and strokes, in the event that they prevented many extra hip fractures, then it’d lead to a good risk-benefit ratio. So, how efficient are calcium dietary supplements in stopping hip fractures? We’ve identified that milk consumption doesn’t seem to assist, however possibly that’s as a result of any potential advantage of the calcium in milk could also be overshadowed by the elevated threat of fracture and loss of life related to the galactose sugar in milk. So, what about simply the calcium in a calcium complement alone? Calcium consumption generally doesn’t appear to be associated to hip fracture threat in any respect, and when folks have been given calcium dietary supplements, not solely was there no discount in hip fracture threat, an elevated threat is feasible. The randomized managed trials steered a 64% higher threat of hip fractures with calcium supplementation in comparison with simply getting like a placebo sugar tablet.
The place then did we even get this concept that taking calcium dietary supplements may assist our bones? It was this influential research, in 1992, that discovered {that a} mixture of vitamin D and calcium dietary supplements may scale back hip fracture charges 43%. However, this was accomplished on institutionalized girls, like in a nursing residence, who have been vitamin D poor. They weren’t getting ample solar publicity. And, so, if you happen to’re vitamin D poor and you’re taking vitamin D and calcium, no shock your bones get higher, however for ladies dwelling independently, out locally, the most recent official suggestions for calcium and vitamin D supplementation to forestall osteoporosis are unambigious: Don’t complement. Why? As a result of within the absence of compelling proof for profit, taking dietary supplements shouldn’t be price any threat, regardless of how small. Now, this isn’t to say these dietary supplements don’t play a job in treating osteoporosis, or that vitamin D dietary supplements won’t be good for different issues, however if you happen to’re simply attempting to forestall fractures, girls dwelling exterior of establishments shouldn’t take them and maybe even in establishments. On this research, as a substitute of giving nursing residence residents vitamin D and calcium dietary supplements, they randomized them to daylight publicity and calcium dietary supplements, and people who received the calcium capsules had considerably elevated mortality, lived shorter lives than the sunshine solely group.
Though calcium dietary supplements don’t seem to forestall hip fractures, they might scale back total fracture threat by like 10%. So, right here’s how the risk-benefit shakes out. If a thousand folks took calcium dietary supplements for 5 years, we’d anticipate 14 extra coronary heart assaults, that means 14 folks would have a coronary heart assault that will not have had a coronary heart assault in the event that they hadn’t began the calcium dietary supplements. So, they have been successfully going to the shop and shopping for one thing that gave them a coronary heart assault, plus ten strokes that in any other case wouldn’t have occurred, and 13 deaths—individuals who would have been alive had they not began the dietary supplements. However, that’s all balanced towards the 26 fractures that will have been prevented. Now, it’s no enjoyable falling down and breaking your wrist or one thing, however I believe most individuals would have a look at threat profit evaluation and conclude that calcium dietary supplements are doing extra hurt than good.
Given these findings, using these dietary supplements must be discouraged, and people suggested to acquire calcium from their weight-reduction plan as a substitute. Calcium dietary supplements have been related to elevated threat of myocardial infarction (coronary heart assaults), whereas dietary calcium consumption has not. How a lot calcium ought to we shoot for? Curiously, in contrast to most different vitamins, there’s no worldwide consensus. For instance, within the UK, the advice for adults is 700 mg a day, however throughout the pond within the US, it’s as much as 1,200 a day. Every time I see that type of big discrepancy between authorities panels, I instantly assume scientific uncertainty, political maneuverings, or each.
Newer information, primarily based on calcium steadiness research during which researchers make detailed measurements of the calcium going out and in of individuals, recommend that the calcium requirement for women and men is decrease than beforehand estimated. They discovered calcium steadiness was extremely resistant to vary throughout a broad vary of intakes, that means our physique shouldn’t be silly. If we eat much less calcium, our physique absorbs extra and excretes much less, and if we eat extra calcium, we take in much less and excrete extra to remain in steadiness. Subsequently, present proof means that dietary calcium consumption shouldn’t be one thing most individuals want to fret about.
This will clarify why in most research, no relationship was discovered between calcium consumption and bone loss anyplace within the skeleton, as a result of the physique simply type of takes care of it. Don’t push it too far, although. When you get right down to just some hundred milligrams a day, it’s possible you’ll get considerably extra bone loss. Although there is probably not nice proof to assist the U.S. suggestions, the UK could have the proper thought taking pictures for between 500 and 1,000 mg a day from dietary sources until you’ve had gastric bypass surgical procedure or one thing and must take dietary supplements. For most individuals, although, calcium dietary supplements can’t be thought of secure or efficient for stopping bone fractures.
(video ends)
OK, so calcium dietary supplements look like doing extra hurt than good. What about taking vitamin D dietary supplements?
(video begins – Ought to Vitamin D Be Taken to Stop Falls?)
We’ve identified for over 400 years that muscle weak point is a standard presenting symptom of vitamin D deficiency. Bones aren’t the one organs that reply to vitamin D; muscle tissues do too. However, as we age, our muscle tissues lose vitamin D receptors, maybe serving to to clarify the loss in muscle energy as we age.
And certainly, vitamin D standing does seem to foretell the decline in bodily efficiency as we age, with decrease vitamin D ranges linked to poorer efficiency. However, possibly the low vitamin D doesn’t result in weak point; possibly the weak point results in low vitamin D. Vitamin D is the sunshine vitamin, and so, if you happen to’re too weak to run round exterior, that might clarify the correlation with decrease ranges. To see if it’s trigger and impact, you must put it to the take a look at.
There’s been a couple of dozen randomized managed trials: vitamin D dietary supplements versus sugar capsules. Put all of the research collectively, and older women and men do get important safety from falls with vitamin D, particularly amongst those that begin out with comparatively low ranges, main the conservative USPSTF, the U.S. Preventive Companies Job Power, the official prevention guideline-setting physique, and the American Geriatric Society to advocate vitamin D supplementation for these at excessive threat for falls.
We’re not fairly positive of the mechanism, although. Randomized, managed trials have discovered that vitamin D boosts world muscle energy, significantly within the quads, that are vital for fall prevention—although vitamin D dietary supplements have additionally been proven to enhance steadiness. So, it might even be a neurological impact, or perhaps a cognitive impact. We’ve identified for about 20 years that older women and men who cease strolling when a dialog begins are at significantly excessive threat of falling. Over a six-month timeframe, few of those that may stroll and speak on the similar time would go on to fall, however 80% of those that stopped when a dialog was initiated ended up falling.
Different excessive threat teams that ought to complement embrace those that’ve already fallen as soon as, or are unsteady, or on quite a lot of coronary heart, mind, and blood strain medication that may improve fall threat. There’s additionally a take a look at referred to as “Get-Up-and-Go,” which anybody can do at residence. You time how lengthy it takes you “to stand up from an armchair, stroll 10 toes, flip round, stroll again, and sit down.” If it takes you longer than ten seconds, then it’s possible you’ll be at excessive threat.
So, how a lot vitamin D must you take? It appears to take a minimum of 700 to a thousand models a day. The American Geriatric Society recommends a complete of 4,000 a day, although, primarily based on the rationale that this could get about 90% of individuals as much as the goal vitamin D blood stage of 75 nanomoles per liter. 1,000 ought to do it for almost all of individuals, 51%, however they advocate 4,000 to seize 92% of the inhabitants. Then, you don’t should routinely take a look at ranges, because you would get most individuals up there, and it’s significantly beneath the proposed higher tolerable consumption of 10,000 a day. They do not advocate periodic megadoses.
As a result of it’s laborious to get sufferers to adjust to capsules, why not simply give folks one megadose, like 500,000 models, every year, like once you are available in in your flu shot, or one thing? That means, yearly, you’ll be able to a minimum of assure an annual spike in D ranges that lasts a number of months. It’s unnatural, however actually handy (for the physician, a minimum of). The issue is that it truly will increase fall threat—a 30% improve in falls in these first three months of the spike. Related outcomes have been present in different megadose trials. It might be a matter of “an excessive amount of of factor.”
See, “vitamin D could enhance bodily efficiency, scale back continual ache, and enhance temper” a lot that you simply begin shifting round extra, and, thereby, improve fall threat. You give folks a whopping dose of D, and also you get a burst in bodily, psychological, and social functioning, and it might take time in your motor management to meet up with your improved muscle perform. It could be like giving somebody a sports activities automobile all of a sudden once they’ve been used to driving some beater. You gotta take it gradual.
It’s potential, although, that such unnaturally excessive doses may very well harm the muscle tissues. The proof they cite in assist is a meat business research displaying you’ll be able to enhance the tenderness of steaks by feeding steers a number of million models of vitamin D. So, the priority is that such excessive doses could also be over-tenderizing our personal muscle tissues, as properly. So, yeah, increased D ranges are related to a progressive drop in fracture threat, however an excessive amount of vitamin D could also be dangerous.
The underside line is that vitamin D supplementation seems to assist, however the strongest and most constant proof for prevention of great falls is train. Should you evaluate the 2, sure, taking vitamin D could decrease your fall threat, in comparison with placebo. However, energy and steadiness coaching, with or with out vitamin D, could also be much more highly effective.
(video ends)
So periodic annual and even month-to-month mega-doses could improve threat. What’s the perfect each day dosing? Let me share a research that got here out after I completed that video which may be enlightening:
OK so what we’re taking a look at here’s a year-long randomized double-blind placebo-controlled trial of seven totally different each day doses of vitamin D for aged girls who began out low in D, which discovered that the low doses appeared ineffective, 400 or 800 IU a day, however there was a major discount in fall charges amongst these taking the medium doses (1,600, 2,400, or 3,200 models a day), and a considerably increased fall price taking 4,000 a day or 10,000 a day in comparison with the medium doses.
And a 3 12 months research discovered increased doses, 4,000 or 10,000 a day, might also decrease bone mineral density
OK, let’s return to the movies. After I say it’s higher to get calcium from meals, most individuals instantly assume dairy, however two movies in the past you’ll have caught me saying “milk consumption doesn’t seem to assist, however possibly that’s as a result of any potential advantage of the calcium in milk could also be overshadowed by the elevated threat of fracture and loss of life related to the galactose sugar in milk.” Wait, what? Let’s undoubtedly tackle that:
(video begins — Is Milk Good For Our Bones?)
Milk is touted to construct robust bones, however a compilation of all the perfect research discovered no affiliation between milk consumption and hip fracture threat, so consuming milk as an grownup won’t assist bones. However what about in adolescence? Harvard researchers determined to place it to the take a look at.
Research have proven that higher milk consumption throughout childhood and adolescence contributes to peak bone mass, and is due to this fact anticipated to assist keep away from osteoporosis and bone fractures in later life. However that’s not what they discovered. Milk consumption throughout teenage years was not related to a decrease threat of hip fracture, and, if something, milk consumption was related to a borderline improve in fracture threat in males.
It seems that the additional increase in whole physique bone mineral density you get from getting further calcium is misplaced inside a number of years, even if you happen to preserve the calcium supplementation up. This means a partial clarification for the long-standing enigma that hip fracture charges are highest in populations with the best milk consumption. Possibly an reason they’re not decrease, however why would they be increased?
This enigma irked a Swedish analysis group, puzzled as a result of research time and again had proven an inclination of a increased threat of fracture with the next consumption of milk. Effectively, there’s a uncommon start defect referred to as galactosemia, the place infants are born with out the enzymes wanted to detoxify the galactose present in milk, so that they find yourself with elevated ranges of galactose of their blood, which might trigger bone loss at the same time as youngsters. So possibly, the Swedish researchers figured, even in regular individuals who can detoxify the stuff, it won’t be good for the bones to be consuming it day by day. And galactose doesn’t simply harm the bones. That’s what scientists use to trigger untimely growing old in lab animals They slip them a bit of galactose and you may shorten their lifespan, trigger oxidative stress, irritation, mind degeneration, simply with the equal of 1 to 2 glasses of milk’s price of galactose a day. We’re not rats, although—however given the excessive quantity of galactose in milk, suggestions to extend milk consumption for prevention of fractures could possibly be a conceivable contradiction. So that they determined to place it to the take a look at, taking a look at milk consumption and mortality, in addition to fracture threat, to check their principle.
100 thousand women and men adopted for as much as 20 years; what did they discover? Milk-drinking girls had increased charges of loss of life, extra coronary heart illness, and considerably extra most cancers for every glass of milk. Three glasses a day was related to almost twice the chance of loss of life. And so they had considerably extra bone and hip fractures too.
Males in a separate research additionally had the next price of loss of life with increased milk consumption, however a minimum of they didn’t have increased fracture charges. So a dose-dependent increased price of each mortality and fracture in girls, and the next price of mortality in males with milk consumption, however the reverse for different dairy merchandise like soured milk and yogurt, which might go together with the galactose principle, since micro organism can ferment away a number of the lactose. To show it although, we want a randomized managed trial to look at the impact of milk consumption on mortality and fractures. Because the accompanying editorial identified, we higher determine this out quickly, as milk consumption is on the rise world wide.

Darn proper we higher determine this out!
With the then largest ever research on milk consumption and mortality displaying such hostile results, Harvard researchers stepped in with three of their cohorts to kind a research twice as huge to see if what the Swedish findings have been a fluke. Following greater than 200,000 women and men for as much as three a long time, in 2019 they confirmed the dangerous information. Those that consumed extra dairy lived considerably shorter lives. Each half serving extra of standard milk a day was related to 9% elevated threat of dying from heart problems, 11% elevated threat of dying from most cancers, and an 11% elevated threat of dying from all causes put collectively.
However wait, extremely influential advocacy organizations, such because the U.S. Nationwide Osteoporosis Basis or the Europe-based Worldwide Osteoporosis Basis, proceed to push dairy, medication, and calcium dietary supplements. Maybe their objectivity is compromised by the affect of their business sponsors, which embrace firms that market (you guessed it) dairy, medication, and dietary supplements.
OK, so what meals could assist out bones? Let’s flip to that subsequent:
(video begins — Why Fruits and Greens Could Cut back Osteoporosis Threat)
Even only a single further serving of vegetables and fruit per day is related to decrease bone fracture threat. Why? Effectively, osteoporotic fracture threat is related to increased ranges of irritation in your blood, for instance C-reactive protein, and particularly, a extra pro-inflammatory weight-reduction plan. These consuming increased on the dietary inflammatory index have a couple of 30% higher related threat of osteoporosis and fracture than these consuming extra anti-inflammatory diets, and the next consumption of fruit and greens decreases irritation. In order that’s one potential cause.
Free radicals might also play a job in consuming away at your bone, suggesting that pro-oxidant stress could contribute to osteoporosis. Each the full antioxidant energy and capability of individuals’s bloodstreams and diets are considerably decrease in these with osteoporosis, And the way can we squash free radicals and enhance antioxidant standing? With, vegetables and fruit. For instance, consumption of vitamin C-rich meals is related to decrease threat of hip fracture, osteoporosis, and bone loss. Each extra improve of 50mg of dietary vitamin C a day, which is concerning the quantity in a single orange, could decrease the chance of hip fracture by 5 %.
The third means vegetables and fruit could assist our bones are by way of acid-base steadiness. As we get older, there’s a slight drop within the pH of our blood as our blood turns into extra acidic with age. That is considered because of the waning capacity of our kidneys to exCRETE extra acid. In vitro research recommend a drop in pH could result in activation of the cells that break down bone and an inhibition of cells that construct bone again up. So how about consuming alkaline-forming meals?
Probably the most acid-forming meals are meat and cheese, particularly fish, and essentially the most alkaline, or base-forming meals, are vegetables and fruit. This will assist clarify why if you happen to experimentally take away vegetables and fruit from folks’s diets, a marker of bone formation considerably drops, and a marker of bone loss shoots up, and vice-versa once you then add vegetables and fruit again into their each day diets.
The higher the estimated ratio between acid-forming meals and alkaline-forming meals, the higher the chance of hip fracture, supporting the rationale to eat much less acidic diets, however this was primarily based on observational information. To show cause-and-effect, two-year double-blind, randomized managed trials have been carried out during which the three added servings of vegetables and fruit or the equal of six further servings, didn’t have an impact. However randomize folks to the equal of 9 each day servings of vegetables and fruit price of an alkaline-forming compound, and also you do see a major improve in bone quantity and density within the backbone, hip, and all through the entire physique.
Are there any vegetables and fruit which can be significantly good? That’s the query I’ll tackle, subsequent.
(video ends)
OK so observational research recommend fruit and vegetable consumption could assist shield our bones, and an interventional trial of an alkaline load equal to 9 servings a day improved bone quantity and density. Have any particular fruits or greens been examined? Sure, test it out:
(video begins — Onions and Tomatoes Put to the Check for Osteoporosis)
Feeding rats dozens of various meals, the fruit discovered to protect their bones the perfect was the prune, and the main vegetable was the onion. I’ve talked already about prunes. What about onions?
The nation with apparently the best per capita consumption of onions on the earth is Turkey, which additionally has one of many lowest charges of osteoporotic bone fractures. Turkey could have 4 instances higher each day per capita onion consumption than the USA and 4 instances decrease hip fracture chances. Is that only a coincidence although?
The issue with attempting to correlate country-by-country comparisons is that you simply don’t know if the folks inside these nations who’re truly consuming these onions are those who’re truly avoiding fractures. However in 2017 a potential research was printed during which the fruit and vegetable consumption of about 1,500 older girls was adopted for almost 15 years and of the entire lessons of greens, the consumption of allium household veggies (reminiscent of onions, leeks, and garlic) have been those most related to decrease threat of bone fractures.
Based mostly on a research of non-Hispanic white girls 50 years and older, those that ate onions each day had an total bone density 5% higher than those that not often ate them. Which will sound like so much, however may doubtlessly translate into decreasing the chance of hip fracture by greater than 20%.
Why onions? Possibly it’s the quercetin. Onions are one of the concentrated sources of this phytonutrient, which might stimulate the exercise of our bone-building cells, a minimum of in a petri dish, and can be a potent inhibitor of the formation of latest bone-eating cells.
Or may or not it’s the fructan-fiber-prebiotics in onions? Experimentally infused into the rectum, the short-chain fatty acids created by our fiber-eating intestine flora have been proven to stimulate calcium absorption, a lot in order that adolescents randomized to the kind of fiber present in onions—about an onion a day’s price for a 12 months, considerably elevated their bone mineral density over the placebo group.
Within the rodent bone preservation research, various spices beat out prunes and onions, with the highest canine being one other allium, garlic. And within the potential human research, cruciferous greens like broccoli got here in at an in depth second to the allium household. Though there are some petri dish information supporting the potential bone advantages of the sulforaphane in cruciferous veggies, inhibiting the formation of bone consuming cells, and it seems to guard bone well being in mice, the explanation I’m singling out onions, is that it’s one among solely two greens which have truly been put to the take a look at in medical trials.
However how are you going to give you a placebo onion for the management group? That’s, why a bunch of revolutionary Chinese language researchers gave folks onion juice, versus a pretend onion juice. (I don’t know which sounds worse, however, something for science!) And, these randomized to the true onion group skilled an enchancment in a marker of bone loss over the placebo, however the research didn’t final lengthy sufficient to see if this translated into tangible bone advantages. However a medical trial on the opposite vegetable put to the take a look at, did.
The tomato story, begins out, just like the onion story. There’s epidemiological assist: Within the Framingham Osteoporosis Research, increased intakes of lycopene, the pink pigment in tomatoes, have been related to safety towards bone loss in older women and men over a interval of 4 years, in addition to safety towards hip fractures over seventeen years. Maybe this helps clarify why research present that elevated adherence to a extra Mediterranean-style weight-reduction plan is related to about 20% fewer hip fractures.
Then there’s laboratory proof: Lycopene inhibits bone loss in a petri dish and preserves bone mass in rats. Nevertheless, so does a inexperienced tomato extract, which is richer in compounds reminiscent of tomatine relatively than lycopene, so possibly there are a number of protecting elements in tomatoes. Anyway, let’s feed folks some tomato merchandise and see what occurs!
Postmenopausal girls randomized to lycopene within the type of a couple of cup and a 3rd of standard tomato juice a day skilled a major discount in a marker of bone loss by month two, and the other was discovered after only a month of proscribing lycopene consumption (so no tomatoes, watermelon, or different pink fruits like pink grapefruit). This means that simply common dietary intakes are protecting. However does this translate into retaining considerably extra bone over time? Postmenopausal girls given about two-thirds of a cup of tomato sauce a day for 3 months suffered considerably much less bone loss than these in an age-matched group who didn’t, although it doesn’t seem that the research topics have been assigned randomly, which may bias the outcomes.
So, ought to we exit of our strategy to embrace these particular vegetables and fruit in our weight-reduction plan? Usually we’re simply left with a “can’t-hurt” shrug, however a bunch of New Zealand researchers put collectively a randomized managed trial to seek out out. They developed the Scarborough Truthful Food plan (named for the presence of presumptive bone-protecting herbs parsley, sage, rosemary, and thyme from the music popularized by Simon and Garfunkel). The weight-reduction plan included prunes, onions, and tomatoes. They in contrast that to a weight-reduction plan equally full of 9 or extra servings of vegetables and fruit, however ones that weren’t suspected as having significantly skeleton-saving properties. Markers of bone turnover have been measured after three months, and the specifically concocted weight-reduction plan of bone-preserving produce did no considerably higher than the weight-reduction plan full of non-bone preserving produce, or a weight-reduction plan with simply 6 servings of fruits and veggies a day, suggesting that the main target ought to simply be on stuffing your face with vegetables and fruit of any stripe.

So relatively than selecting or selecting particular bone-boosting produce, the bottomline, primarily based predominantly on the acid/base research is to only most likely eat extra vegetables and fruit generally. Allow us to flip to train. What’s the greatest kind and frequency of bodily exercise for bone well being?
(video begins— The Greatest Train Sort and Frequency for Bone Density)
In terms of bone well being, it’s use it or lose it. Bodily exercise is taken into account a broadly accessible, low-cost, and extremely modifiable contributor to bone well being. Train transmits forces by way of the skeleton, producing alerts which can be detected by your bone-building cells. This is the reason the Nationwide Osteoporosis Basis, Worldwide Osteoporosis Basis, and different businesses advocate weight-bearing workout routines for the prevention of osteoporosis. These embrace high-impact workout routines reminiscent of leaping, aerobics, and operating, in addition to decrease impression workout routines like strolling and weight coaching to create these mechanical alerts that spark bone progress, however ample depth and frequency are vital. The big variation in bone profit throughout totally different research, from negligible adjustments to substantial enhancements in bone mineral density, has been attributed to the adequacy of the train regime.
To enhance measures of bone energy on the backbone and hip, the best train coaching protocol seems to be a mixture of progressive resistance and impression coaching at reasonable to excessive depth. Low depth train doesn’t look like ample. For instance, whereas common strolling is commonly prescribed to forestall osteoporosis, it seems to supply restricted profit for bone loss prevention. By itself, strolling has no important impact on bone mineral density within the backbone, wrist, or total skeleton, nevertheless it has been proven to considerably enhance hip bone density in research which have lasted greater than 6 months. Simpler can be brisk strolling, strolling with a weighted vest, or combining strolling with extra vigorous workout routines reminiscent of jogging, stepping, or stair-climbing. Non-impact actions reminiscent of biking or swimming have been proven to have little or no impact.
A chic research to find out the optimum frequency of high-impact train for bone well being concerned hopping on one randomly chosen foot, with the particular person’s different leg appearing because the management. Girls have been randomized to hop 50 instances on that one, similar leg both seven days per week, 4 days per week, two days per week, or under no circumstances for six months. And the transient, each day hopping elevated hip bone density, however much less frequent hopping was not efficient. The one group who constructed considerably extra bone of their hip on the leaping in comparison with non-jumping aspect inside these 6 months was the seven-day-a-week group. Should you soar 50 instances with a couple of 10 pound weighted vest on, nevertheless, you might be able to protect your hip bone density with simply three periods per week as a substitute of day by day.
Be aware, weight-bearing impression train could also be contraindicated, that means not advisable, in these with extreme osteoporosis or current historical past of fracture so ensure you test in together with your medical skilled earlier than you get going.
(video ends)
I really like that hopping research. Sensible! The best advantage of train could don’t have anything to do with bone mineral density, although, as I clarify the video I’ll shut out on, entitled “The Single Most Necessary Factor to Do to Stop Osteoporosis Bone Fractures”
(video begins — Fall Prevention Is the Most Necessary Factor for Stopping Osteoporosis Bone Fractures)
Bone mineral density screening could also be a billion-dollar business, however solely 15% of low trauma fractures (that means from a fall not more than from standing peak) are on account of osteoporosis in older girls. Solely 15% of fractures are on account of having low bone density. Between the ages of 60 and 80, hip fracture threat will increase 13-fold in women and men, whereas the age-related decline in bone mineral density accounted for less than a twofold elevated threat, so the contribution of declining bone density to the exponential improve in hip fracture threat with age is comparatively small. The overwhelming majority of our age-related rise in hip fracture threat seems to don’t have anything to do with the measured density of our bones.
With no fall, even fragile hips don’t fracture. Falls are the first reason for fractures—together with vertebral fractures. The disparity between women and men in hip fracture charges is primarily not as a result of males have stronger bones, however as a result of girls fall extra usually. Medical doctors simply asking the straightforward query “Do you will have impaired steadiness?” can predict about 40% of all hip fractures, greater than a bone scan prognosis of osteoporosis. Even a weak osteoporotic bone is robust sufficient survive regular life actions with out the extreme loading that comes from a fall impression or, within the case of the backbone, bending together with your again to raise one thing relatively than your knees.
The primacy of falls in fracture threat explains, various obvious osteoporosis paradoxes. For instance, even supposing about 75% of your bone mass could also be decided by your genes, the heritability of bone fractures seems negligible at older ages, (as a result of the propensity to fall is far much less inherited).
It additionally explains the poor predictive worth of bone density screening for fractures. Including bone mineral density measures to a hip threat rating primarily based simply on age, intercourse, peak, weight, using a strolling help, and cigarette smoking standing did little to enhance its predictive energy. A provocative editorial printed within the Journal of Inside Drugs entitled “Osteoporosis: The Emperor Has No Garments” steered that it could be safer and simpler to give attention to fall prevention relatively than pharmaceutical intervention.
Although solely about 5% of falls lead to a fracture, falls are quite common amongst the aged. Due partly to age-related muscle weak point, and lack of steadiness, greater than a 3rd of these aged 65 and older fall every year. After a hip fracture, fewer than 50% regain their pre-fracture perform when it comes to strolling capacity and independence. What can we do to forestall injurious falls primarily based on dozens of randomized managed trials? The only intervention most strongly related to a discount in fall charges? Train. So, train doesn’t simply increase bone density. Extra importantly, it additionally reduces the variety of falls over time by 23% and the variety of fallers by 15%. So if you happen to adopted 1,000 folks round age 75 for a 12 months and 480 fell a complete of 850 instances with out train, including train can be anticipated to lead to 72 fewer fallers and 195 fewer falls.
Tai Chi seems to cut back falls by 19%, steadiness and practical workout routines (like sit to face) could scale back falls by 24%, and a number of workout routines—usually steadiness and practical train plus energy coaching—could scale back falls by 34%.
The diminished falls price then interprets into fewer fractures. A current meta-analysis discovered that train interventions—largely utilizing a mixture of resistance train to enhance decrease limb muscle energy coaching and steadiness coaching—reduce fracture charges almost in half. One year-long trial that mixed energy coaching with step and leaping aerobics, and centered on steadiness and agility resulted in, 74% fewer fractures over the 5 12 months interval after the research ended. Moreover, greater than 70% of the ladies within the combo train group went these 5 years with out a single injurious fall, in comparison with lower than half of these within the management group.
Trials on hip protectors, which cushion a sideways fall on the hip with plastic shields or foam pads sewn into particular underwear, are sometimes plagued with poor compliance. Research haven’t discovered them to be helpful for decreasing hip fracture charges amongst these dwelling at residence, however trials in nursing houses or residential care amenities do present a small discount in threat, translating into about 11 fewer folks out of a thousand struggling hip fractures on account of carrying hip safety.
There are additionally common sense measures one can make use of. High quality enchancment trials involving interventions like affected person training have proven a ten% discount in fall charges. For instance, preserve issues inside attain so that you don’t want use step stools. Use non-slip mats within the tub and bathe, add seize bars within the lavatory, preserve flooring litter free, take away small throw rugs or use double-sided tape to maintain them from slipping, and ensure all staircases have handrails and sufficient lighting. You might additionally keep away from taking walks throughout inclement climate and for individuals who stroll leashed canine, take into account selecting smaller breeds, or guaranteeing correct coaching to forestall them from lunging. In any other case, the primary methods to forestall fractures could not have modified a lot over the a long time, because the traditional paper entitled “Methods for Prevention of Osteoporosis and Hip Fracture.” The principle methods to forestall these fractures are to “quit smoking, be energetic and eat properly.”
(video ends)
OK, so we’ve got this bone mineral density-focused mindset in drugs for osteoporosis, as a result of there are billions of {dollars} invested in scanning and drugging folks to trace and enhance their bone density, however solely a small proportion of hip fracture threat has something to do with bone density. So it’s similar to many of the threat of life-style illnesses like atherosclerotic coronary heart illness or hypertension has to do with weight-reduction plan and life-style, the cash is within the medication and procedures in order that’s the place our focus has been, but when we actually simply cared about folks not breaking bones we’d be specializing in falls, and we’ve got this miracle intervention referred to as train—resistance train to enhance decrease limb muscle energy coaching mixed with steadiness coaching slicing fracture charges in half—beating out medication, with solely optimistic unwanted effects.
