A healthy diet in one particular decade can help prevent dementia

Eating a healthy diet at the age of 43 has been found to keep your brain functioning well and reduce the risk of dementia later in life. 

But that doesn’t mean you only have to eat well for one year.

A new study following people and their diets over decades found that what they ate at 43 had a significant impact on memory decline in later life. Until now, studies on dementia have mainly focused on the eating habits of people in their 60s and 70s.
