Mediterranean diet 'can protect against memory loss'

It has been hailed as the secret to a long life and has been shown to prevent heart disease and depression.
Now, researchers have found the Mediterranean diet can protect against memory loss, too.
A study found people who eat a Mediterranean-style diet may be less likely to experience declines in their memory and thinking skills. The diet consists of plant-based foods such as vegetables, legumes, fruit, nuts, seeds and olives, extra virgin olive oil, fish, with moderate red wine intake. It also involves a low consumption of processed food, processed carbohydrates, sweets and chocolate and red meat.
As part of the study, researchers followed 27,860 people in 40 countries for an average of around five years. They were all 55 or older and had diabetes or a history of heart disease, stroke or peripheral artery disease, a common condition in which a build-up of fatty deposits in the arteries restricts blood supply to leg muscles.
