Chameleons Eye/ShutterstockFor someone with celiac disease, a gluten-free diet isn’t a choice; it’s a necessity. But many non-celiacs choose to cut out gluten, citing a wide range of benefits, such as improved cardiovascular health. However, two new studies conclude that a gluten-free diet won’t help protect against heart disease. (By the way, if you think you might have celiac disease, here are the symptoms to look for.)
Researchers, including Andrew T. Chan, MD, of Massachusetts General Hospital and Harvard Medical School, and Peter H.R. Green, MD, of the Celiac Disease Center at Columbia University in New York City, studied 64,714 women in the Nurses’ Health Study, and 45,303 men in the Health Professionals Follow-up Study. All participants completed a food frequency questionnaire in 1986 that was updated every four years through 2010. Patients were followed until the development of coronary heart disease, death, or the end of follow-up in 2012. The researchers based the quantity of gluten consumed by each participant on the protein content of wheat, rye, and barley, and then divided the participants into fifths of estimated gluten consumption, according to energy-adjusted grams of gluten per day.

While a gluten free diet can work for many people, celiac or not, it doesn’t come without risks. The biggest is simply missing out on a healthy, well-balanced diet that includes foods like whole grains, which have important nutrients like fiber, iron, zinc, folate, niacin, thiamine, riboflavin, calcium, vitamin B12 and phosphorus. What’s more, refined foods processed to earn a gluten-free label (e.g. pastries, energy bars, etc. made with potato starch or rice starch) are also often higher in calories than their gluten-containing alternatives.

Losangela/ShutterstockThe amount of grains you need each day for optimum heart health depends on your age, gender, and calorie needs, according to The American Heart Association. Current guidelines recommend six servings of grains per day for a 1,600 calorie diet, and six to eight servings per day for a 2,000 calorie diet. Examples of one serving include one slice of bread, 1 ounce of dry cereal, five whole-grain crackers, three cups of unsalted, air-popped popcorn, and a half-cup of cooked rice, pasta, or cereal. At least half of your grains should be whole grains—such as whole wheat, oats, rye, barley, corn, popcorn, brown rice, wild rice, buckwheat, millet, and quinoa.
