The Food and Drug Administration will not issue a final ruling Monday about trans fats as previously announced, although the announcement is “imminent,” according to agency spokesperson Megan McSeveney.

The FDA is expected to revoke the “generally accepted as safe” classification for partially hydrogenated oils, the main source of trans fats in processed foods. Trans fats are expected to be designated as food additives, which must have FDA authorization to be used in food products.

Partially hydrogenated oils are a major source of trans fats, which increase the risk of heart disease, according to the American Heart Association. These oils are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid.

Trans fats can be found in many foods, including fried foods such as doughnuts, and baked goods such as cakes, pie crusts, biscuits, frozen pizza, cookies, crackers and stick margarines and other spreads. It is listed on the food’s Nutrition Facts panel.

Trans fats raise bad LDL cholesterol levels and lower good HDL cholesterol. Trans fats may also be associated with an increased risk of stroke and Type 2 diabetes, according to research.
