Too many carbs and sugars can lead to cognitive impairment

New study by Mayo clinic researchers shows that those aged 70 and older who consume large amounts of food high in carbohydrates and sugar have a significantly higher risk of developing cognitive impairment.

The study, published in the Journal of Alzheimer’s disease, researched 940 people, ages 70-90, that showed no signs of cognitive impairment. After four years, 200 started to show irregular signs of mild cognitive impairment. It was found that those participants that had a high intake of carbohydrates or sugar were nearly twice as likely to suffer with cognitive impairment as those who consumed smaller amounts. It was however found that those whose diets were highest in fats, were 42% less likely to suffer with cognitive developments.

This is thought to be due to a high intake of carbohydrates can have an impact on glucose and isulin levels. Too much sugar can prevent the brain from using it and cause similar effects to type 2 diabetes.
