Overeating may double risk of memory loss
New research suggests that consuming between 2,100 and 6,000 calories per day may double the risk of memory loss, or mild cognitive impairment (MCI), among people age 70 and older. The study was released today and will be presented at the American Academy of Neurology’s 64th Annual Meeting in New Orleans April 21 to April 28, 2012. MCI is the stage between normal memory loss that comes with aging and early Alzheimer’s disease.
“We observed a dose-response pattern which simply means; the higher the amount of calories consumed each day, the higher the risk of MCI,” said study author Yonas E. Geda, MD, MSc, with the Mayo Clinic in Scottsdale, Arizona and a member of the American Academy of Neurology.
The study involved 1,233 people between the ages of 70 and 89 and free of dementia residing in Olmsted County, Minn. Of those, 163 had MCI. Participants reported the amount of calories they ate or drank in a food questionnaire and were divided into three equal groups based on their daily caloric consumption. One-third of the participants consumed between 600 and 1,526 calories per day, one-third between 1,526 and 2,143 and one-third consumed between 2,143 and 6,000 calories per day.
The odds of having MCI more than doubled for those in the highest calorie-consuming group compared to those in the lowest calorie-consuming group. The results were the same after adjusting for history of stroke, diabetes, amount of education, and other factors that can affect risk of memory loss. There was no significant difference in risk for the middle group.
“Cutting calories and eating foods that make up a healthy diet may be a simpler way to prevent memory loss as we age,” said Geda.
Overeating is a disorder which not only affects physical health but causes a lot of stress at the mental and emotional level also. Some people tend to eat just because they feel bored or they have nothing to do! Others get into such undesirable habits to improve their physical appearance.
Emotional mood swings like anger, sadness, distress, disappointment or betrayal makes people eat a lot more than they realize. In certain cases, medications for other treatments cause hunger due to which people start eating a lot.

Over-eating could more than double the risk of memory loss among elderly people, a study has found. It suggests keeping to a frugal diet in old age could help keep the mind sharp and prevent the onset of Alzheimer’s disease which affects 820,000 people in Britain. Scientists in the U.S. looked at the eating and drinking habits of 1,200 people aged 70 to 89 who did not have dementia - and gave them memory tests. They found 163 had memory problems and the odds were more than doubled for those in the highest calorie-consuming group compared with the lowest. The results were despite the scientists adjusting for other factors influencing memory loss such as history of stroke, diabetes, depression and educational levels.
