A new study found that elderly people who ate more calories a day are at higher risk for a type of memory loss called mild cognitive impairment (MCI). Those with MCI have noticeable problems with their memory and thought process, but they do not have an effect on daily activity. Researchers surveyed 1,233 people ages 70-89. The higher caloric intake group reported to be consuming between a range of 2,143-6000 calories per day. Those in the higher caloric intake group were twice as likely to have MCI than those eating less than 1, 543 calories a day. It’s unclear why the amount of calories consumed may affect memory, but some scientists theorize that excessive calorie intake may stimulate stress proteins in the brain, which may contribute to memory loss.
