Battle of the bread basket continues

A battle over the breadbasket brews as advocates and experts take sides - either for or against the grain. Called into question are the health benefits of eating wheat and other gluten-containing grains including barley and rye.

“Carbohydrates are awful for the brain,” claims neurologist Dr. David Perlmutter, author of a new diet book, “Grain Brain.” He says even those without celiac disease or gluten intolerance should avoid most whole grains.

“Eating carbohydrate foods increases blood sugar levels, which causes inflammation and can lead to dementia,” he says.

Nothing could be further from the truth, according to nutrition experts who point out that carbohydrate foods provide glucose, the preferred fuel of the brain and contain nutrients such as B vitamins beneficial to brain health.

“Research shows that grains, especially low glycemic intact whole grains, reduce inflammation. They are part of the solution, not part of the problem,” says Cynthia Harriman, director of food and nutrition strategies for the Whole Grains Council. She cites a recent University of Nebraska study that showed eating whole grains (barley and brown rice) helped decrease inflammation.

Perlmutter is particularly critical of wheat as a culprit in obesity and degenerative brain diseases such as Alzheimer’s. Judy Adams, registered dietitian and president of the Wheat Foods Council, responds by saying, “He can’t connect the increase in obesity rates and incidence of brain health problems with the consumption of wheat. We are actually eating less wheat today than we were one hundred years ago.”

A growing number of people are being diagnosed with a sensitivity to gluten that can cause a range of health problems. But nutrition experts in the United States and Canada say there is no evidence that gluten containing whole grains poses widespread health risks for the rest of the population. In fact, quite the opposite could happen.

Dietitians of Canada issued a statement saying, “Diets that eliminate gluten, carbohydrates or categories of foods without medical justification may put the health of Canadians at risk.” Harriman says a study by researchers at the Centers for Disease Control and Prevention projected diets would be extremely low in folic acid and iron and fall short of B vitamins if whole grains were eliminated. She adds even those with a gluten digestion problem have their choice of many nutritious gluten-free grains to enjoy, including amaranth, buckwheat, corn, millet, oats (if certified as noncontaminated), quinoa, rice, sorghum, teff and wild rice.
