We look to food labels for many things. We hunt down the calorie count if we are watching our weight, we check out the serving size, we skim through the ingredients to make sure we are not allergic to any of them and we often peer down the ingredient list to make sure there aren't too many chemicals.
While food labels do house so much important information about our groceries, they often don't tell us the full story. Brands are not required to put certain ingredients on the label that you may want to know about.
Check out the slideshow above to learn which ingredients may be left off food labels and why.
