High Carb Diet Bad For Elderly Cognitive Function

Just say no!

Seniors who follow a high-carbohydrate diet are nearly four times as likely to develop mild cognitive impairment, especially if their food intake is high in sugar, researchers from the Mayo Clinic report in the Journal of Alzheimer's Disease. They also found that seniors whose diets are high in protein and fat are less likely to develop cognitive impairment.

The researchers found that:

      

    The highest carbohydrate eaters had a 1.9 times higher risk of mild cognitive impairment than the participants who ate the fewest carbs.

             

   The highest sugar consumers had a 1.5 times higher risk of cognitive impairment compared to the lowest consumers.           

    

   The participants with the highest fat intake had a 42% lower risk of developing cognitive impairment compared to the lowest fat eaters.

            

   The highest protein consumers had a 21% lower chance of developing dementia compared to the lowest consumers of protein.

      

   When taking into account fat and protein intake, the highest carb eaters had a 3.6 times higher chance of developing mild cognitive impairment.
