The team of American researchers studied the effects of diet on 1,233 people between the ages of 70 and 89
The participants were split into three groups: one on a high calorie diet (1,142 to 6,000 calories a day), one on a medium calorie diet (1,526 to 2,142 calories a day), and one on a low calorie diet (600 to 1,526 calories a day).
The cognitive abilities of each group were then tested and compared to identify any incidences of mild cognitive impairment (MCI).
The results, presented at the yearly meeting of the American Academy of Neurology, showed no difference in the low and middle groups. However, participants in the high calorie group demonstrated more than double the incidence of MCI.
Dr Yonas Geda, one of the researchers involved in the study, said: “Cutting calories and eating foods that make up a healthy diet may be a simpler way to prevent memory loss as we age.”
More research needs to be conducted into the relationship between food and cognitive ability. However, most experts agree that a healthy, balanced diet should help to improve both memory and mental health to some extent.
