The Food and Drug Administration made it official on Tuesday. It removed hydrogenated oils for the list of food additives it considers safe to consume.

As a result manufactures have three years to remove hydrogenated oils their products unless the FDA has granted them approval to continue to use them.

Those oils, designed to give processed foods longer shelf lives, have been used since the '50s and their also the leading contributor to added trans fats in the diets of Americans.

According to the Los Angeles Times Thirteen years ago, researchers concluded that trans fats raise LDL cholesterol levels, which is a leading factor in heart disease.

This is the latest move in the FDA's battle against trans fats. In 2006, they made manufactures list the amount of trans fats in their foods, and in 2013, it said it had started the process to remove trans fats from the food supply in the U.S.
