FDA to trans fats: Get the h*ll outta here!

More than a decade ago, a sea change began in the American diet, with consumers starting to avoid foods with trans fat and companies responding byreducing the amount of trans fat in their products.

This evolution began when FDA first proposed in 1999 that manufacturers be required to declare the amount of trans fat on Nutrition Facts labels because of public health concerns. That requirement became effective in 2006.

However, there are still many processed foods made with partially hydrogenated oils (PHOs), the major dietary source of trans fat in processed food. Trans fat has been linked to an increased risk of coronary heart disease, in which plaque builds up inside the arteries and may cause a heart attack.

The Centers for Disease Control and Prevention estimates that a further reduction oftrans fat in the food supply can prevent an additional 7,000 deaths from heart disease each year and up to 20,000 heart attacks each year.

Part of the FDA’s responsibility to the public is to ensure that food in the American food supply is safe. Therefore, due to the risks associated with consuming PHOs, FDA has issued aFederal Register notice with its preliminary determination that PHOs are no longer “generally recognized as safe,” or GRAS, for short. If this preliminary determination is finalized, then PHOs would become food additives subject to premarket approval by FDA. Foods containing unapproved food additives are considered adulterated under U.S. law, meaning they cannot legally be sold.

If FDA determines that PHOs are not GRAS, it could, in effect, mean the end of artificial, industrially-produced trans fat in foods, says Dennis M. Keefe, Ph.D., director of FDA’s Office of Food Additive Safety. FDA is soliciting comments on how such an action would impact small businesses and how to ensure a smooth transition if a final determination is issued.

Trans fat wouldn’t be completely gone, Keefe notes, because it also occurs naturally in small amounts in meat and dairy products. It is also present at very low levels in other edible oils, such as fully hydrogenated oils, where it is unavoidably produced during the manufacturing process.

About Trans Fat and PHOs

PHOs are found in many popular processed foods, like baked goods and frozen foods that time-crunched Americans use to feed their families. They have been widely used as ingredients since the 1950s to increase the shelf-life and flavor stability of foods.

But over time, various studies have linked transfat—produced when hydrogen is added to vegetable oil to make it more solid—to heart disease. A 2002 report by the National Academy of Science’s Institute of Medicine found a direct correlation between intake of trans fat and increased levels of low density lipoprotein (LDL) cholesterol, commonly referred to as “bad” cholesterol, and, therefore, increased risk of heart disease.

Keefe says that even though the FDA requirement that trans fat be listed on the Nutrition Facts label took effect in January 2006, consumers took the health warnings to heart early. They started turning away from foods withtrans fat soon after publication of FDA’s final rule in 2003. Taking the lead from consumers, many processed food manufacturers followed suit and voluntarily changed their food formulations to reduce or eliminate transfat.

However, Mical E. Honigfort, a consumer safety officer at FDA, says that trans fat can still be found in such processed foods as:

  • crackers, cookies, cakes, frozen pies and other baked goods
  • snack foods (such as microwave popcorn)
  • frozen pizza
  • vegetable shortenings and stick margarines
  • coffee creamers
  • refrigerated dough products (such as biscuits and cinnamon rolls)
  • ready-to-use frostings

About GRAS

Under section 409 of the Federal Food, Drug, and Cosmetic Act, any substance intentionally added to food is a food additive subject to premarket approval and review by FDA, with some exceptions. The exceptions include substances “generally recognized as safe,” or GRAS, because they are generally recognized by qualified experts as safe under the conditions of intended use.

The most widely used PHOs have long been considered GRAS ingredients by the food industry. Keefe explains that companies may voluntarily notify FDA that they have determined that the use of an ingredient is GRAS, but there is no legal requirement for food manufacturers to submit a GRAS notification before going to market. If FDA ultimately determines that PHOs are not GRAS, food manufacturers would have to obtain premarket approval by FDA before adding PHOs to food.

FDA can act when it believes an ingredient is, in fact, not GRAS. And that’s what the agency’s preliminary determination is doing now with partially hydrogenated oils. A Federal Register notice was published on Nov., 7 2013 announcing the preliminary determination that PHOs are not GRAS, which includes the opening of a 60-day public comment period.

If FDA makes a final determination that PHOs are not GRAS, the agency and food industry would have to figure out a way to phase out the use of PHOs over time. To help address this concern in an appropriate manner, the Federal Register notice calls for comment on how long it would take the food industry to phase out its use of PHOs.

What Should the Consumer Do?

In the meantime, what should the average consumer do if he or she picks up a favorite food and sees that it has trans fat on the Nutrition Facts label? The best thing to do is to consider the amounts of saturated fat, cholesterol and trans fat. Choose the product that has the lowest combined amount of these nutrients, Keefe says.

Even if a food claims on its packaging to have “0 grams trans fat,” it’s a good idea to look at the ingredients, says Honigfort. Under current regulations, companies can make that claim if the food contains less than 0.5 grams of trans fat per serving. But if there is partially hydrogenated oil listed with the ingredients, there might be a small amount of trans fat. Selecting foods with even small amounts of trans fat can add up to a significant intake.

  1. A little late don’t you think? It’s been know for at least 50 years that PHO was not a food but a chemical. The author failed to mention that during a good part of those 50 years the FDA, the ADA, AMA, the AHA all recommended replacing saturated fat with poly unstaturated fat; use margarine not butter. In fact the FDA encouraged food manufacturers to use PHO’s- before they recommended taking the fat our of foods totally and replacing them with starch and sugar.
    About the last place I’d look for dietary advice is the FDA. Anyone with a head and an interest in health stopped sing PHO’s decades ago.
