It is the fabulously talented bell pepper (also known as capsicum) that led me to adding the pepper family to the Top 20 Superfoods. In the main, I wanted to recognise it as a high source of vitamin C, as a big yellow bell pepper has 341mg of it - that's roughly the same as five whole oranges! One red bell pepper equates to three oranges and the green bell pepper, which is a little less sweet, still contains twice the vitamin C found in an orange. Green peppers are in fact red bell peppers that have not yet ripened. As they ripen, they become sweeter and the vitamin C content increases. Orange and yellow varieties are specially bred to offer colour variety, and are also sweeter in taste. Bell peppers aren't just about vitamin C, as just one pepper provides approximately 10% of our daily fibre requirements, plus they also contain vitamin A, vitamin B6, magnesium and potassium.
