Mediterranean diet ‘may slow the ageing process by five years’

US survey shows older people who follow vegetable-rich diet have brain volume greater than those who do not

Eating a Mediterranean diet rich in fish and vegetables may help prevent your brain shrinking for as long as five years, new research suggests.

People who follow such a diet, which also involves consuming less meat and dairy products than average, end up with bigger brains and slow down the ageing process, according to the US study.
