Revealed: The 20 'functional foods' you should be eating for a long and active life

They are the foods you need for a long and active life - and it will not be much of a surprise that most are fruit and vegetables. But there are still some everyday pleasures, such as tea, coffee and chocolate, on a list of the foodstuffs which could help you live to a ripe old age.

The 20 types of food and drink have been identified by Gary Williamson, professor of 'functional foods' at Leeds University, and he recommends that we should all make them part of our diets. He has coined the phrase ' lifespanessential' to describe the key foodstuffs, all of which contain chemicals called polyphenols. The chemicals are produced by plants and are known for their antioxidant properties, helping prevent cancer and heart disease.

On his list, alongside such familiar 'superfoods' as broccoli, blueberries and spinach, are black or green tea, dark chocolate and coffee.

Some processed versions are also allowable - along with whole oranges, freshly-squeezed orange juice retains many of the same health benefits. The same also applies to red grapes and red wine, meaning a little luxury is compatible with living for as long as possible.
