A study by the Mayo Clinic (USA) reveals that eating between 2,100 and 6,000 calories a day doubles the risk of memory loss in old age . Or what is the same, that the more calories we consume, the more likely it is that when we turn 70 we will suffer cognitive decline, the step prior to the development of Alzheimer's disease.
In their experiments, the researchers worked with more than 1,200 people ages 70 to 89. A third of the participants consumed 600 to 1,526 calories per day, as many ingested foods with a caloric intake of 1,526 to 2,143, and the rest of the subjects consumed between 2,143 and 6,000 calories every 24 hours. The results showed that the number of individuals suffering from cognitive impairment in the last group was twice that of the first group. The researchers, who will reveal the details of their work at the next meeting of the American Academy of Neurology in April, say that these negative effects are independent of the cynical history of heart attacks and whether or not they suffered from diabetes. And they recommend a healthy diet with a limited number of calories, especially when reaching old age, to preserve memory.
