Scientists have come to a single opinion - walnuts stimulate the human brain. In the course of the research representatives of the University of San Francisco, revealed the connection between blood iron and dementia. If the iron is not enough, the person develops anemia and red blood cell count decreases. The red blood cells responsible for oxygen transfer, if not, then the brain activity is reduced, because there is a shortage of oxygen.
But this can be avoided with proper nutrition. Experts recommend eating more walnuts. In the diet should include legumes, fish and meat steaks, liver. Quite a good effect has a Mediterranean diet, which includes consumption of vegetables and fruits. Close attention to the content of iron in the blood should be paid to those who are already 65.
