The FDA wants to do away with trans fat in processed foods, hoping to prevent heart attacks and other heart disease.
The agency today issued a finding that partially hydrogenated oils, the primary dietary source of artificial trans fat in processed foods, are not “generally recognized as safe” for use in food. The FDA’s preliminary determination is based on available scientific evidence and the findings of expert scientific panels.
“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,” said FDA Commissioner Margaret A. Hamburg, M.D. “The FDA’s action today is an important step toward protecting more Americans from the potential dangers oftrans fat. Further reduction in the amount of trans fat in the American diet could prevent an additional 20,000 heart attacks and 7,000 deaths from heart disease each year – a critical step in the protection of Americans’ health.”
Consumption of trans fat raises low-density lipoprotein (LDL), or “bad” cholesterol, increasing the risk of coronary heart disease. The independent Institute of Medicine (IOM) has concluded that trans fat provides no known health benefit and that there is no safe level of consumption of artificial trans fat. Additionally, the IOM recommends that consumption of trans fat should be as low as possible while consuming a nutritionally adequate diet.
Powerful promoter of heart disease
"Artificial trans fat is a uniquely powerful promoter of heart disease, and today's announcement will hasten its eventual disappearance from the food supply," said Michael F. Jacobson, executive director of the Center for Science in the Public Interest. "Not only is artificial trans fat not safe, it's not remotely necessary. Many companies, large and small, have switched to healthier oils over the past decade. I hope that those restaurants and food manufacturers that still use this harmful ingredient see the writing on the wall and promptly replace it."
In recent years, many food manufacturers and retailers have voluntarily decreased trans fat levels in many foods and products they sell. Trans fat can be found in some processed foods, such as certain desserts, microwave popcorn products, frozen pizzas, margarines and coffee creamers. Numerous retailers and manufacturers have already demonstrated that many of these products can be made without trans fat.
Though small amounts of trans fat occur in meat fat and milk fat, most of the trans fat in the food supply has come from industrially produced partially hydrogenated oils. Like saturated fat, trans fat raises one's LDL, or "bad" cholesterol, which promotes heart disease.
But unlike saturated fat, trans fat lowers one's HDL, or the "good" kind of cholesterol that protects against heart disease. Trans fat may also promote heart disease in other ways, such as by damaging the endothelial cells that line blood vessels.
>“One of the FDA’s core regulatory functions is ensuring that food, including all substances added to food, is safe,” said Michael Taylor, the FDA’s deputy commissioner for foods and veterinary medicine. “Food manufacturers have voluntarily decreased trans fat levels in many foods in recent years, but a substantial number of products still contain partially hydrogenated oils, which are the major source of trans fat in processed food.”
If the FDA finalizes its preliminary determination, PHOs would be considered “food additives” and could not be used in food unless authorized by regulation.
