Need more evidence that meat is “brain food”? A study from the Mayo Clinic found that elderly people who consume lots of protein and fat relative to carbohydrates are less likely to have their thinking impaired.
Researchers tracked the eating habits of 1,230 people ages 70 to 89 over four years. Those whose diets were highest in fat were 42 percent less likely to face cognitive impairment, and those who had the highest intake of protein had a reduced risk of 21 percent. When total fat and protein were considered, people with the highest carbohydrate intake were 3.6 times more likely to develop mild cognitive impairment.
“We think it’s important that you eat a healthy balance of protein, carbohydrates and fat, because each of these nutrients has an important role in the body,” said lead study author Rosebud Roberts, a Mayo Clinic epidemiologist.
The findings were published in the Journal of Alzheimer’s Disease.
