The revelations are based on a a survey where 3 groups of healthy people ages 70 to 89 were separated into three groups based on the amount of calories they consume each day. One group had a relatively low daily caloric intake (600 to <1,526), the second group had a medium level (1,526 to 2,142.5), and the last group had a very high number (2,142.5 to 6,000 kcal/day). After completing the survey the group with the high level of daily calories showed the highest risk for Mild Cognitive Impairment (MCI). MCI is the stage of memory loss that is more than normal memory loss that comes with aging, and just before the amount that comes with the first stages of Alzheimer's. The middle group showed similar results, while the lower calorie group showed half as much risk.
The implications of the study are that overeating, already known to be a health risk, also increases your odds of having greater than normal memory loss issues when you are older. Beyond that, even if you're not an over eater, it seems you're better off keeping your calorie intake under control, to keep your chances lower of getting MCI or worse as you get into those golden years.
