The one-fourth of people with the highest percent intake of protein (20% of calories) were 21% less likely to have mild cognitive impairment or dementia compare to the one-fourth of people with the lowest percent protein intake (16% of calories) according to a study from researchers at the Mayo Clinic in Rochester, Minnesota, USA.
“A dietary pattern with relatively high caloric intake from carbohydrates and low caloric intake from fat and proteins may increase the risk of [mild cognitive impairment] or dementia in elderly persons,” the authors of the study concluded.
The study involved 2719 people aged 70-89 years-old.
“Median age was 79.5 years, 51% were male, 40% had ≤ 12 years of education, and 65% were married” the paper notes.
