(WKBW/ABC) A lot of people avoid eating foods with trans fats, but if you are relying on the product's label, you may not be getting the whole story.
The truth is the Food and Drug Administration doesn't require food companies to mention trans fats if the amount is less than half a gram per serving size.
A "serving size" of potato chips may have less than half a gram of trans fat, but a serving may be only five chips.
So, even though the package label says "zero" trans fats, if you are consuming more than five chips, you are actually consuming trans fats without knowing it.
Experts all agree that trans fats are a health hazard, possibly contributing to heart disease, diabetes, and cancer.
