Can Eating Too Many Calories Cause Memory Loss in the Elderly?

A study performed by the Mayo Clinic suggests that overeating can more than double the risk of mild cognitive impairment (MCI) in the elderly. While the study is only a preliminary one, it suggests that cutting calories may be a simple way to prevent or slow memory loss as people age. Mild cognitive impairment is a decline in mental abilities, chiefly memory, that's noticeable but not severe enough to affect the performance of day to day activities.
