How eating too much could double risk of memory loss
Dailymail- Overeating could more than double the risk of memory loss among elderly people, a study has found.
Researchers discovered that those who consumed more than 2,100 calories a day were far more likely to have 'mild cognitive impairment' than those who ate less.
The findings suggest that keeping to a low-calorie diet in old age could keep the mind sharp – and may even prevent the onset of Alzheimer's disease.
Scientists in the U.S. looked at the eating and drinking habits of 1,200 people aged 70 to 89 who did not have dementia, and gave them memory tests.
They found that 163 had developed memory problems – and the risk was more than twice as high for those who consumed the most calories.
The connection was clear even after the scientists had adjusted the data to account for other factors that could influence memory loss, such as educational levels or a history of strokes, diabetes or depression.
The researchers had divided the study participants into three groups: one included people consuming 600 to 1,500 calories a day, with another for those consuming 1,500 to 2,100, and a third for those consuming 2,100 to 6,000.
