Orange and Red:
Green vegetables are excellent sources of vitamin K, folic acid, potassium, as well as carotenoids and omega-3 fatty acids. Folic acid is needed to prevent neural tube defects during pregnancy, and vitamin K is essential in blood clot formation. Diets high in potassium are associated with lowering blood pressure, and there is an inverse relationship between cruciferous vegetables and cancer, especially colon and bladder cancers.
Blue and Purple:
While many white foods are refined, like white bread and white rice, there are a lot of white foods that are packed with nutrients. White fruits and veggies have been linked to lower cholesterol, decreased blood pressure, and a lower risk of heart disease. The key benefit of white foods is increased immunity.
Pineapple, yellow peppers, corn, star fruit, and other yellow foods contain nutrients that promote good digestion and optimal brain function. High in alpha- and beta-carotenes, yellow foods have also been linked to increased immunity, a decreased risk of some cancers, and healthy eyes and skin.
