How Can Salad Dressing Be Labeled as 'Fat Free'?

A salad dressing with vegetable oil can be labeled as “fat free” if it contains no fat or only a physiologically insignificant amount (<0.5%) per serving, according to the regulations mentioned in. This is because commercially available reduced-fat dressings typically contain 3 g or less of fat per serving, and fat-free products are defined as those that contain no fat or only a very small amount of fat per serving. Therefore, if a salad dressing meets these criteria, it can be labeled as “fat free”.
