Consistently overeating may lead to memory loss among the elderly according to a new study conducted by researchers at the Mayo Clinic in the United States.
More than 1,200 elderly people between ages of 70 and 89 years took part in the study. The participants were divided into three groups with the first group being given a low calorie diet of less than 1,526 calories a day; the second group followed a middle diet of 1,526 to 2,142.5 calories a day while the third group had a daily calorie intake of 2,142.5 to 6,000 calories.
The researchers found that those who followed the high calorie diet displayed a substantial mild cognitive impairment (MCI) incidence compared to the other two groups. "We observed a dose-response pattern which simply means; the higher the amount of calories consumed each day, the higher the risk of MCI", lead researcher Dr Yonas Geda said.
