Dear Andaziwa
All fruits and vegetables are healthy foods, but some contain more vitamins than others. The vegetables that are dark green or dark yellow/orange in colour are rich in a beta-carotene which is converted into vitamin A in the body. We need vit A to keep all our membranes and the skin healthy and resistant to infection. Now "orange" coloured fruits like oranges and naartjies don't really fall into tis category because it is the skin or peel that is dark orange and we don't usually eat the peel. However, the citrus fruits (oranges, lemons, grapefruit, naartjies) are very rich in vitamin C which helps us to prevent colds and other infections and boosts immunity. Then there are the red vegetables, esp tomatoes which contain lycopene which is believed to protect us again certain cancers, esp prostate cancer in med. Dark purple vegies like beetroot are also rich in so-called antioxidants which prevent degenerative diseases (heart disease, cancer, diabetes, etc).
The best plan is to eat at least 5 servings of fresh veg and fruit a day to keep healthy.
