Apples, known as a cleansing food, contain fibre, antioxidants and fruit flavonoids. The most important of the flavonoids contained in apples is quercetin, which has anti-inflammatory as well as anti-cancer actions. Apples contain vitamin C as well – more so in green apples than in red ones. Apples can reduce blood cholesterol levels, counter constipation and diarrhoea, help joint problems and help prevent diseases in general.

Apples are best eaten raw, as cooking them can reduce the flavonoids by as much as 70 percent into the cooking water. It is also a good idea to eat the apple unpeeled as flavonoids are contained in or near the skin.
