Now, there may be another reason to push back from the dinner table and ignore those high-calorie sweets.
Researchers at the Mayo Clinic wanted to know if there was any association between increased caloric intake and the risk of developing mild cognitive impairment or MCI.
Dr. Yonas Geda, a psychiatrist and expert on neurology at the Mayo Clinic, describes MCI as a gray zone between the forgetfulness of normal aging and dementia.
In the study, more than 1,200 people aged 70 to 89 were divided into three equal groups based on how many calories they consumed each day.
Dr. Geda says they found that the risk of MCI went up for those who ate the most - more than 2,100 calories per day. In fact, it more than doubled. His conclusion based on this study:
"Watching ones diet has benefit for many things," Geda said. "What's good for the heart is good for the brain."
