Reading food labels

In the United States, a food label can show 0 grams of trans fat if a food has less than 0.5 grams of trans fat in a serving.

Products made before the FDA ban of added trans fat might still be for sale. So check to see if a food's ingredient list says partially hydrogenated oil. If it does, that means the food has some trans fat in it, even if the amount is below 0.5 grams.

These hidden trans fats can add up quickly. That's especially true if you eat many servings of foods that have less than 0.5 grams a serving.
