Since 2014 there have been 386 studies, 153 of which are randomised controlled trials, which show what dietary and lifestyle factors have the best evidence for the prevention of Alzheimer’s disease.

A review of these studies published in 2020, headed by Professor Jin-Tai Yu from the Department and Institute of Neurology in Shanghai’s Fudan University, showed that the best evidence for the prevention of Alzheimer’s are by:

Controlling your weight

Lowering blood homocysteine with B vitamins

Controlling blood sugar and preventing diabetes, which means a low sugar and low glycemic load diet

Achieving sufficient omega-3 fat intake, primarily from seafood

Eating a ‘Mediterranean’ diet with fruit, vegetables and vitamin C

Controlling your blood pressure, helped by all the above

Preventing depression, stress and a lack of sleep

Keeping physically, socially and intellectually active

Not smoking or drinking alcohol excessively.

These factors are all addressed through our cognitive function test, which includes a dietary an lifestyle questionnaire that will give you personalised recommendations based on the answers you've given.
