FDA Trans Fat Labeling Guidelines
The FDA regulations allow manufacturers of any food product with less than 0.5g of trans fat to list “0g” on the nutrition label. With that much leeway, it’s hard to know exactly how much trans fat you’re eating. For example, just two tablespoon servings of a margarine containing partially hydrogenated oils, but labeled 0g trans fats, can contain up to almost 1g of trans fat. Eat a few pieces of toast at breakfast with two servings of one of these margarines, and you’re half way to your AHA recommended daily limit by the end of breakfast.
