The rainbow means will not be about restriction however fairly a predominance of entire, plant-based meals together with a number of objects that keep what Browne known as the “sensory expertise of meals, together with its social and cultural points.”
All it takes goes again to the fundamentals and ensuring that the plate accommodates the entire main plant colours: crimson, orange, yellow, inexperienced, and blue-purple.
Pink
Assume beets, strawberries, cherries, and crimson bell peppers. These meals are wealthy in antioxidants and comprise vitamins that assist the physique combat irritation and keep a wholesome immune response.
