People in the age group of 70 and above, a diet containing large amounts of carbohydrates, four times greater risk of developing umstennyh rastrojstvami. The same danger lurks and lovers of sugar, as found by researchers from Mayo Clinic. Those who consume a lot of protein and fat, as compared with carbohydrates are less likely to develop such disease. The results of the study were published in the journal Journal of Alzheimer’s Disease.
This study emphasizes the importance of a balanced diet, says lead author Rosbad Roberds, an epidemiologist at the Mayo Clinic.
"We believe it is important to eat a healthy ratio of protein, carbohydrates and fat, because each of these components plays an important role in the body," - said Dr. Roberts.
The scientists collected information on 1,230 patients aged 70 to 89 years who reported eating during the previous year. Their brains were evaluated by an expert panel of doctors, nurses and neuropsychologists. Of these, only 940 showed no signs of cognitive impairments and asked to return them to assess their mental capacity in the future. About a year later, 200 of these 940 have begun to show signs of mental decline, such as problems with memory, speech, thoughts and judgments that went beyond the norm for their age.
Those who consumed more carbohydrates in the beginning of the study had a 1.9 times greater chance of mental decline than those with a low-carbohydrate diet. Participants with the highest sugar content of up to 1.5 times more likely to experience mental decline than those with more moderate levels of consumption.
But those whose diets were rich in fat, 42 percent less likely to have experienced cognitive decline, and people with the highest consumption of proteins in this group have experienced these symptoms for 21 percent less.
Taking into account the total amount of fat and protein taken, the people with the highest amount of carbohydrates is 3.6 times more likely to suffer from reduced cognitive abilities.
"High levels of carbohydrates can lead to problems as they affect the metabolism of glucose and insulin," - said Dr. Roberts. "Sugar feeds the brain, however moderate amounts not so bad. However, at higher doses coupon sugar brain loses its ability to use it, just as occurs in type 2 diabetes."
