No more trans fat: FDA banning the artery-clogger

Products containing artificial trans fats linger in an array of processed foods, including pancake mix, packaged cookies and ready-made frosting.

Know your fats

There are three main types of fats in food: unsaturated, saturated and trans fats. While the FDA is moving to ban artificial trans fats, they are not the only types of fats that can cause heart disease.

Unsaturated fat: These are the good fats, and doctors say they should be the majority of the fat that people eat. Some of the main sources are nuts, vegetable oils and fish. For cooking, they usually come in the form of liquid oils, not solid fats. Types of unsaturated fats include polyunsaturated and monounsaturated.

Saturated fat: These fats are mostly derived from animals and generally take a more solid form. They raise “bad” cholesterol and can contribute to heart disease. Common sources include high-fat cheeses, high-fat cuts of meat, whole-fat milk, butter, and palm and coconut oils. The government recommends that saturated fats make up less than 10 percent of daily calories.

Trans fat: These are the worst fats, and the FDA recommended that artificial trans fats be phased out. They are made when hydrogen is added to vegetable oil, usually to create a certain consistency or increase shelf life; they are also called partially hydrogenated oils. Many have already been phased out, but foods that are more likely to contain trans fats are fried items, microwave popcorn, frozen pizza, cakes, cookies, pie crusts, stick margarine, ready-to-use frosting and coffee creamers. There are also some naturally occurring trans fats from meat and dairy sources, but the artificial types make up most of what is in the food supply.

WASHINGTON — Artificial trans fats, a key ingredient in everything from pastries to pizzas to microwave popcorn for generations, will be banished from America’s food supply under a new federal proposal because of their risk to public health.

The Food and Drug Administration (FDA) on Thursday took the first steps toward eliminating the artery-clogging substance, saying the change could prevent 20,000 heart attacks and 7,000 deaths caused by heart disease each year.

Products containing trans fats have increasingly disappeared from stores and restaurant menus in recent years amid widespread agreement about the risks they pose to public health. But trans fats linger in an array of processed foods, including pancake mix, packaged cookies and ready-made frosting.

Thursday’s action, one of the FDA’s most aggressive efforts to limit Americans’ consumption of a specific food ingredient, was aimed at ending the era of trans fats altogether. “While consumption of potentially harmful trans fat has declined over the last two decades in the United States, current intake remains a significant public-health concern,” said FDA Commissioner Margaret Hamburg.

Cities such as New York and Philadelphia have previously imposed bans on artificial trans fats in restaurants, and since 2006 the FDA has required food manufacturers to print details about them on nutrition labels. As a result, intake among Americans declined from 4.6 grams of trans fat a day in 2003 to about 1 gram a day last year, according to the agency.

The FDA said Thursday it will accept public comments for 60 days on its proposal. While government officials acknowledged that entirely phasing out trans fats is likely to take years, they said they were confident that it will happen.

Under the FDA proposal, trans fats would no longer be among ingredients in the largely unregulated category known as “generally recognized as safe,” or GRAS. Companies wanting to use trans fats in any foods would have to petition the agency and meet “rigorous safety standards” showing that they would cause no harm to public health, said Michael Taylor, the FDA’s top food-safety official. Given the growing body of evidence about the dangers of trans fats, that could be a tough sell, Taylor said.

In recent years, responding to consumer demand and pressure from regulators, food companies have been removing trans fats from an array of products. Many of the country’s best-known food chains, from Dunkin’ Donuts to Taco Bell to McDonald’s, have been eliminating trans fats in their pastries and fried foods. Wal-Mart has given its suppliers until 2015 to phase out artificial trans fats. Even Crisco, the shortening that has been a staple of American pantries for a century, altered its formula to remove trans fats years ago.

Artificial trans fats became popular during the 1940s, in part because they were cheaper than products made from animal fat and because they proved effective in extending the shelf life of baked and fried foods while creating the desired taste and texture. “They were an innovation at the time,” said Robert Collette, president of the Institute of Shortening and Edible Oils. “They were cost effective, and they had all these useful characteristics.”

Trans fats come from partially hydrogenated oils, which occur when manufacturers add hydrogen to vegetable oil to make a more solid substance. The result is a versatile product that is typically longer lasting, cheaper and just as functional as animal-based fats such as butter or lard.

As recently as the 1980s, many scientists and public-health advocates believed that partially hydrogenated oils were healthier than the more natural saturated fats they had replaced. By the mid-1990s, more studies made it clear that trans fats increase the level of LDL — bad cholesterol — and put consumers at higher risk for heart disease.

In 1994, advocacy group Center for Science in the Public Interest petitioned the FDA to require that trans fats be listed on nutrition labels. In 2002, the Institute of Medicine found that there was “no safe level of trans fatty acids and people should eat as little of them as possible.”

Food-industry representatives said Thursday that companies have made significant strides in recent years to reduce the amount of trans fats on the market. Leon Bruner, chief science officer for the Grocery Manufacturers Association, said that since 2005, “food manufacturers have voluntarily lowered the amounts of trans fats in their products by over 73 percent.”
