The rainbow diet: Health benefits of coloured fruits and vegetables

From white, the brightest orange, to the deepest purple — make your meals and snacks as colourful as possible. Each colour provides unique health benefits and no one colour is superior to another, which is why a balance of all colours is most important. The ultimate goal of a 'rainbow diet' is to add 30 plus different colourful fruits and vegetables to your meals every week. Just plan for one colourful plant-based food at every meal and instead of rich, sugary treats after the meals or for between-meal snacks, use fresh fruits to satisfy the sweet tooth.

Orange- and yellow-coloured foods are rich in Vitamin C and carotenoids, including beta-carotene. They have phytonutrients like red-coloured food that promote healthy vision and cell growth.

Citrus fruits contain hesperidin which increases blood flow and can potentially help prevent strokes. Orange fruits and vegetables also support the reproductive health of men and women.

Yellow foods are particularly good for the digestive tract. They contain prebiotics that encourage our gut bacteria to produce short-chain fatty acids — special molecules that nourish the cells of our gut.

Healthy orange and yellow food include pumpkins, sweet potatoes and carrots, sweet corn, yellow and orange peppers, orange lentils, citrus fruits like lemons, oranges, and grapefruit; pineapples, corns, starfruits, papayas, mangoes, turmeric, yams, peaches, and apricots.

Fruits and vegetables that are blue and purple like eggplants, purple cabbages, beetroots, radishes, purple carrots, black olives, berries (blueberries and blackberries), passion fruits, purple grapes, purple plums, prunes, raisins, and dark cherries are rich in anthocyanins and proanthocyanidins antioxidants. They are amazing for memory, cellular strength, reducing inflammation all over the body, and preventing cellular damage. They also boost the health of the urinary tract and promote healthy ageing.

Fruits and vegetables coloured white support bone health, help to lower cholesterol and reduce inflammation, protect against certain cancers, and balance hormones.

Cauliflower is a cruciferous vegetable rich in a healthy compound called sulforaphane.

Garlic and onions are in the allium family of vegetables and contain the powerful compounds allicin and quercetin that help to reduce the risks of cancer and have anti-inflammatory properties.
