Heart-clogging trans fats were once a staple of the American diet, plentiful in baked goods, microwave popcorn and fried foods. Now, mindful of the health risks, the Food and Drug Administration is getting rid of what is left of them for good.
Condemning artificial trans fats as a threat to public health, the FDA announced Thursday it will require the food industry to phase them out.
Manufacturers already have eliminated many trans fats, responding to criticism from the medical community and to local laws. Even so, the FDA said getting rid of the rest — the average American still eats around a gram of trans fat a day — could prevent 20,000 heart attacks and 7,000 deaths each year.
It will not happen right away. The agency will collect comments for two months before determining a phase-out timetable. Different foods may have different schedules, depending how easy it is to find substitutes.
“We want to do it in a way that doesn’t unduly disrupt markets,” said Michael Taylor, FDA’s deputy commissioner for foods. Still, he says, the food “industry has demonstrated that it is, by and large, feasible to do.”
Indeed, so much already has changed that most Americans will not notice much difference, if any, in food they get at groceries or restaurants.
A handful of other countries have banned them, including Switzerland and Denmark. Other countries have enacted strict labeling laws.
Scientists say there are no health benefits to trans fats. And they can raise levels of “bad” cholesterol, increasing the risk of heart disease, the leading cause of death in the United States. Trans fats are widely considered the worst kind for the body’s heart, even worse than saturated fats, which also can contribute to heart disease.
Trans fats are used both in processed food and in restaurants, often to improve the texture, shelf life or flavor of foods. Though they have been removed from many items, the fats are still found in some baked goods such as pie crusts and biscuits and in ready-to-eat frosting that use the more-solid fats to keep consistency.
They also are sometimes used by restaurants for frying. Many larger chains have phased them out, but smaller restaurants may still get food containing trans fats from suppliers.
How can the government get rid of them? The FDA said it has made a preliminary determination that trans fats no longer fall in the agency’s “generally recognized as safe” category, which covers thousands of additives that manufacturers can add to foods without FDA review. Once trans fats are off the list, anyone who wants to use them would have to petition the agency for a regulation allowing it, and that would likely not be approved.
The fats are created when hydrogen is added to vegetable oil to make it more solid, which is why they are often called partially hydrogenated oils. The FDA is not targeting small amounts of trans fats that occur naturally in some meat and dairy products, because they would be too difficult to remove and are not considered a major public health threat on their own.
Many companies have already phased out trans fats, prompted by new nutrition labels introduced by FDA in 2006 that list trans fats and by an increasing number of local laws, like one in New York City, that have banned them. In 2011, Wal-Mart pledged to remove all artificial trans fats from the foods the company sells by 2016. Recent school lunch guidelines prevent them from being served in cafeterias.
