Seniors who eat too many carbohydrates may be more likely to develop cognitive impairment or memory problems, which may lead to Alzheimers.
Carbohydrates Linked to
Cognitive Impairment
NOVEMBER 2012—Seniors who load their plates with pasta, bread and rice may experience diminished brain function, according to a Mayo Clinic study.
Clinic researchers based their results on four years’ worth of data taken from 1,230 residents of Minnesota’s Olmsted County. Study participants were all between the ages of 70 and 89.
A high-carb diet was associated with a fourfold increase in risk of developing mild cognitive impairment, often a precursor to Alzheimer’s disease. In contrast, a high-protein diet lowered risk by 21% and a diet high in fat from nuts and oils dropped risk by 42%. Results were reported in the Journal of Alzheimer's Disease.
When digested, carbohydrates—especially the refined varieties found in white bread, rice and pasta—are broken down into simple sugars within the body. “Sugar fuels your brain, so you need some carbohydrates,” says Mayo epidemiologist Rosebud Roberts, MB, ChB, lead study author. “But too much may stop the brain from using sugars effectively.” Roberts adds that excess sugar in the blood may also spur development of the amyloid plaques associated with Alzheimer’s.
Protein and fat tend to slow the conversion of starchy carbohydrate into sugar, as do the complex carbs found in vegetables and whole grains.
According to results from the Aging, Demographics, and Memory Study released in 2008, mild cognitive impairment affects 22.2% of all Americans 71 years and older, or about 5.4 million people.
