Organic Red capsicums have very high levels of vitamin C and yellow and green capsicums have nearly as much. The red varieties are also rich in beta carotene which the body converts to vitamin A. Vitamin A is important for healthy skin, boosts the immune system, and aids in night blindness.
The reason why red capsicum is the more popular variety is because it contains about 2 teaspoons of natural sugar, making them much more pleasing to the taste buds. Yellow capsicums have almost as much natural sugar, but the green variety have little sugar and so taste a little more bitter. (Organicfood.com)
