Mike Vernuay, professor of epidemiology and radiology at the medical center of the University of Erasmus in the Netherlands, studied how nutrition affects the human brain. The study involved more than 4,000 elderly people whose average age was 66 years. Each participant spoke in detail about their diet and, at the end of the study, underwent an MRI scan of the brain.
According to the results of the study, people who adhered to a healthy Mediterranean diet had a large brain volume: they ate fruits, vegetables and received fats from fish and red meat. They had more gray and white matter that regulate the density of brain tissue, and the hippocampus, the area of the brain responsible for processing and reproducing memories, was better developed.

Scientists analyzed the effects of certain foods on the brain and found that only a combination of nutrients benefits. The increase in brain volume is facilitated by the consumption of a large number of fruits, vegetables, whole grains, nuts, dairy products and fish. Separately, these products do not have the same benefits for the brain and the body. In addition to foods, better brain function is affected by reduced intake of sugar-containing beverages.
Paulin Kroll, co-author of the report, believes that these results can lead to new studies and show the dependence of unhealthy diets and brain disorders.
Scientists plan to continue their work and see if changes in the diet can slow down or stop cognitive impairment of the brain.
