Berries are an antioxidant power food

Are there any particular foods which will help to keep me younger in body and mind?

There is a relatively new system of analysis which measures the antioxidant power of foods, which is thought to help slow the ageing processes that take place throughout the body (including the brain). This system uses oxygen radical absorbance capacity (ORAC), where high ORAC foods are the most beneficial.

At the top of the ORAC list we have a somewhat unlikely food: The prune.
