    Food intolerances refer to a reaction to food that has nothing to do with the immune system. For example, lactose intolerance occurs when a person doesn’t make any or enough enzyme lactase to break down the milk’s sugar lactose. The inability to break this sugar down causes gas, bloating, and diarrhea. It can be challenging to distinguish food intolerances from food sensitivities, anxiety, or other causes of symptoms. People with lactose intolerance can avoid symptoms by avoiding lactose. Knowing and identifying which products contain lactose requires reading labels and learning what is in the dairy category to avoid it!
