Eat a rainbow

The different colours in fruits and vegetables signal the presence of different groups of phytochemicals, so aim to ‘eat a rainbow’ every day to gain maximum health benefits.

Red pigments are antioxidant heroes: anthocyanins and carotenoids. Lycopene, the carotenoid found in tomatoes, packs a powerful antioxidant punch. Vitamin C is also often present.

Green for antioxidants; Vitamin C, flavonoids and carotenoids. Broccoli, cabbage and Brussels sprouts contain antioxidants and contribute significant amounts of fibre, folate, B vitamins, vitamin K, iron, potassium and calcium.

White, tan and brown fruits and veges contain phytochemicals. Allicin, an antibiotic and anti-fungal compound, is found in garlic, leeks and onions. Potatoes make a significant contribution to our intake of vitamin C.

Blue/Purple fruits and vegetables contain health-promoting phytochemicals such as anthocyanins and other antioxidants currently being studied for their antioxidant and anti-aging benefits.

Orange and yellow fruits and vegetables are rich in the antioxidant carotenoids, which also give them their vibrant colours, as well as many other phytochemicals. The yellow-orange group is also a good source of fibre.
