Oranges and Yellows (Carrots, Sweet Potatoes, Oranges): High in vitamins A and C, these sunny delights support eye health and immunity. These have beta-carotene, a nutrient supporting healthy vision, skin, and immune function. They also contain potassium, which may help maintain blood pressure levels.

To add some yellow and orange to your diet, try making a roasted sweet potato or snacking on sliced mango.

Greens (Kale, Spinach, Broccoli): Green is the colour of life. These lively leafy green vegetables like kale and spinach, are loaded with nutrients like iron, vitamin K, and folate. Greens also contains many vitamins – B and E, fibre, and a wide range of important minerals. Both broccoli and Brussels sprouts are other fab green food options as they contain compounds that help fight against cancer.
