Trans fats may be on their way out of U.S. foods.
The Food and Drug Administration has announced plans to have so-called "partially hydrogenated oils (PHOs)," which are the main source of artificial trans fats in processed foods, to be classified as food additives. That means they won't be allowed to be used in food without authorization of the FDA, which may effectively ban the substances.
FDA commissioner Dr. Margaret Hamburg told reporters Wednesday that the action is being considered because PHOs are "not generally recognized as safe for use in food."
The agency will allow 60 days for comments from the public and food manufacturers, asking the latter how long it might take to reformulate current products should the determination be finalized.
The agency pointed out some companies have voluntarily been scaling back the amount of trans fat in foods. But it wants more to be done - an additional 20,000 heart attacks and 7,000 deaths from heart disease each year could be prevented by reducing trans fats, according to the FDA.
"These are significant numbers," said Hamburg.
"While consumption of potentially harmful artificial trans fat has declined over the last two decades in the United States, current intake remains a significant public health concern," she added in a statement. "The FDA's action today is an important step toward protecting more Americans from the potential dangers of trans fat."
The oils behind trans fats can be found in crackers, cookies, frozen pies, other baked goods, microwave popcorn and other snacks, frozen pizza, coffee creamers, refrigerated dough products (like biscuits and cinnamon rolls), ready-to-use frostings, vegetable shortenings and stick margarine, according to the FDA.
Consuming trans fat has been tied to an increased risk for coronary heart disease, a condition in which plaque builds up inside the arteries, which may lead to a heart attack. Previous research, including a 2002 report from the nonpartisan Institute of Medicine, found a direct correlation between eating trans fats and increased levels of "bad" LDL cholesterol, which in turn can increase heart disease risk. The institute recommended against eating any amount of the fats, finding they offered no health benefit.
Trans fat content has been labeled on foods since 2006, and since then, consumption rates have dropped from about 4.6 grams of trans fat per day in 2003, to about 1 gram per day in 2012.
New York City banned trans fats in city's foods in 2006. A 2012 study found that ban caused people to drop their trans fat eating habits by an average 2.4 g less trans fats per day.
People worried about trans fats given the FDA's announcement should look to their Nutrition Facts label and consider products with the lowest combined amounts of saturated fat, cholesterol and trans fat, Dennis M. Keefe, director of FDA's Office of Food Additive Safety, said in an FDA Consumer Update.
