Breakfast Bars and Cereals
Milk isn’t the only dairy in that bowl of cereal. Many cereals, especially granolas, contain milk products like whey, casein or milk powder to boost the protein content of the cereal. Breakfast bars also often contain the same sorts of milk products to boost protein. Unfortunately, it’s not as easy as avoiding the yogurt versions. If in doubt, check the “This product may contain” disclaimer on the side of the box.
