A food label provides nutritional facts like, Calories, Fat, Sodium, Dietary Fiber, Sugars, and Protein. A food label also provides the ingredients in the food product so you can read what is in the food before you eat it in case you are allergic to a certain ingredient or just for the nutritional facts and also the food label provides the vitamins that might be in that certain food. And it also tells you the food you are eating or buying.
Hope this helps!
