Thousands of published scientific studies from around the world have confirmed what Mom and Grandma always said: Eat your greens. Now, the latest research also tells us to eat the blues, the reds, the yellows, and all the other rainbow colours found naturally in fruits and vegetables. Colourful fruits and vegetables contain many disease-fighting compounds known as phytonutrients.
We need the protective benefits of the full spectrum of their bright colors. That’s because the many pigments (colours) in plant foods are nothing short of little chemical factories producing hundreds of their own phyto (plant) nutrients – like polyphenols and flavonoids that protect us from disease.
Red foods help heart, eye and skin health
The reds that colour strawberries, raspberries, cranberries, and cherries are the same reds that give us the antioxidants that prevent cancers and diseases linked to aging. Foods that are red also boost your immune system and enhance brain and heart health. This is because they contain compounds like anthocyanidins and lycopene.
Health benefits of red foods:
Orange/Yellow foods improve immune function & promote eye health
These brightly-colored fruits, vegetables & spices are packed with nutrients that are known to protect the nervous system, promote eye health and prevent heart diseases. Antioxidants are in abundance in orange and yellow foods along with vitamins like vitamin C, beta-carotene, vitamin A, minerals, fiber, and phytonutrients that not only help to decrease your risk of degenerative diseases but are also essential for reducing inflammation. This is because they contain compounds like lutein and zeaxanthin.
Health benefits of orange/yellow foods:
Green foods boost the immune system, detoxify & restore energy
Wheatgrass, barley grass and green algae are the concentrated green foods that are rich in chlorophyll, vitamins, amino acids, and minerals. It’s especially the greens that cleanse and alkalize. Other nutrient-dense greens include organic spirulina, chlorella, moringa, kale, alfalfa and oatgrass. Green foods are anti-inflammatory, support your liver, and are vital for immune health.

Although technically not a colour of the rainbow, white or brown foods like mushrooms, cauliflower, onions and garlic, promote a range of health benefits and should be a regular part of a healthy diet.
