The latest directive from the scientists as to what to eat orders us all to eat more berries to keep our brains young.
Strawberries, blackberries and blueberries contain high levels of compounds called polyphenolics, which help the brain to carry out essential 'housekeeping' functions.
Eating fruits with deep orange, red or blue pigments can even reverse the loss of brain power, according to a two month study of laboratory rats fed a berry-rich diet.
Shibu Poulose, who presented his research at the American Chemical Society on Monday, said: "The good news is that natural compounds called polyphenolics found in fruits, vegetables and nuts have an antioxidant and anti-inflammatory effect that may protect against age-associated decline."
Polyphenolics in berries help certain cells called microglia, which clean up toxic proteins linked to age-related memory loss and other symptoms of mental decline.
So now we have to consume chocolate, milk, red wine and lots of berries. Gets better all the time doesn't it!
