Ward off dementia with ‘brain-boosting’ diet

Researchers at Rush University in Chicago first identified the MIND diet as a way of helping limit dementia through a combination of the Mediterranean diet and the DASH diet

A “brain-boosting” diet can potentially ward off dementia and limit a decline in cognitive functions, according to leading academics.

Researchers at Rush University in Chicago first identified the MIND diet in 2015 as a way of helping limit dementia through a combination of the Mediterranean diet and the DASH diet. The Mediterranean diet stresses the importance of whole grains, fruits, vegetables, and fish. Meanwhile, the DASH diet tries to limit people’s daily salt intake. Academics developed a MIND diet score based on foods that might protect against dementia. Those with the highest score had the slowest rate of cognitive decline.

Dr Martha Clare Morris, along with researchers at Rush University Medical Centre and the Harvard Chan School of Public Health, tracked a group of more than 1,000 older adults who were free of dementia for nine years. The MIND diet involved eating at least three wholegrains a day including oats, quinoa, and brown rice, along with a minimum of six portions of green vegetables, five servings of nuts, two berries, and four beans.

At least two dishes of poultry and one of fish are recommended, while red meat, fried food, and sweets should be avoided. Dr Hussein Yassine, associate professor of neurology at the University of Southern California, told CNBC: “If you take somebody who is not having a nutritious diet, and then they also don’t exercise much, they also don’t sleep well [and] they have risk factors for dementia. And then if you change only one [lifestyle factor], which is in this case the MIND diet, it’s likely to be less effective. It’s not that it’s not effective. [Some] diets have been shown across the board, in many studies, to be associated with less risk of dementia, less risk of brain diseases and longer lifespans.”
