Gluten-Restricted Diets Seem Not to Lower Coronary Risk — Physician’s First Watch
Gluten-Restricted Diets Seem Not to Lower Coronary Risk
By Joe Elia
In people without celiac disease, maintaining a low-gluten diet doesn't decrease cardiac risks, The BMJ reports.
Researchers examined outcomes in some 110,000 health professionals who completed food-frequency questionnaires every 4 years between 1986 and 2010. Those with celiac disease were excluded.
During 25 years of follow-up, those in the highest fifth of gluten intake showed risks for coronary disease actually lower than those in the lowest fifth; however, that difference vanished after multivariable adjustment.
The authors note that one recent national survey found nearly a third of U.S. adults were trying to minimize their gluten intake. Concerned that avoidance of gluten could lower consumption of whole grains, which have cardiovascular benefits, they conclude: "The promotion of gluten-free diets for the purpose of coronary heart disease prevention among asymptomatic people without celiac disease should not be recommended."
