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 just released 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.
At my current weight of 230 pounds, I am eating around 1900 net calories. Of course, this will decrease, with my reduction in body weight.
But, at least I am under the threshold of daily calories at present.
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.
