Researchers found that people who consumed more than 2,100 calories per day had a greater chance to make "slight reduction in cognitive abilities" than those who ate less.
The results indicate that the limit of low calorific diet of later years may hold oshtinata of mind and can even prevent the onset of Alzheimer's disease.
Scientists from the U.S. following the food habits of 1,200 people aged between 70 and 89 years who had dementia, their long strides and memory tests. They found that people prone to overeating have twice the risk of memory problems, reports Daily Mail.
The author of the study, Dr. Jonas Gida of the Mayo Clinic in Scottsdale, Arizona, noted that the study clearly shows how excess calories adversely affects memory, while appealing to a healthy and moderate diet. Concluded that age is one of the most challenging of memory loss, but a healthy diet may in good measure to prevent this.
If the diet is added and physical activity, the effects are much better.
