U.S. Bans Artificial Trans Fats—But Hidden Risks Still Linger in Food

The U.S. has taken significant steps to remove artificial trans fats from its food supply. In 2015, the Food and Drug Administration ruled that partially hydrogenated oils were no longer safe for consumption. This decision led to a nationwide ban on artificial trans fats in processed foods by 2020. The FDA first determined in 2015 that partially hydrogenated oils could not be classified as 'generally recognized as safe'. These oils, the primary source of artificial trans fats, were widely used in packaged and fried foods. By January 2020, food manufacturers were prohibited from selling products containing them.

Artificial trans fats are created during industrial food processing. Unlike naturally occurring trans fats in animal products, they have been shown to raise harmful LDL cholesterol and lower beneficial HDL cholesterol. This increases the risk of heart disease, inflammation, and certain cancers, including prostate and colorectal cancer. They may also impact birth weight during pregnancy.

Despite the ban, small amounts of trans fats can still appear in some packaged foods. Labels are not required to list trans fats if a serving contains less than 0.5 grams. To avoid them entirely, consumers are advised to check ingredient lists for 'partially hydrogenated oil' and choose whole, unprocessed, or plant-based foods. The removal of artificial trans fats from the U.S. food supply is seen as a major public health success. These fats offer no nutritional benefits and pose serious health risks. The ban aims to reduce diet-related diseases, though some trace amounts may remain in certain products.
