What is the requirement for trans fats labeling?

• A. FDA mandated it must be labeled if there is over 0.5 grams/ serving.
• B. It must be labeled if there is over 3 grams per serving.
• C. It is not required to label.
• D. It is only required for dietary supplements.

Answer: (A)

Trans fats labeling is driven by a specific regulatory threshold: if a serving contains 0.5 g or more of trans fat, the Nutrition Facts panel must list the amount of trans fat. This requirement helps consumers gauge and limit trans fat intake because even small amounts can add up with more servings. When a serving has less than 0.5 g, the amount can be rounded to 0 g on the label, which is why the 0.5 g per serving rule matters. The rule applies to standard packaged foods with Nutrition Facts panels, not to all dietary supplements, and the 0.5 g threshold—not 3 g—is the key point.
