Top 10 Foods Highest in Lactose

Lactose is a sugar created by the combination of galactose and glucose. Lactose is found primarily in milk (dairy) foods.

At an early age almost everyone has the ability to digest lactose since it is an important source of energy from nursing milk. Later on in life some people lose the ability to digest lactose and suffer from lactose intolerance. (1)

Symptoms of lactose intolerance include gas, diarrhea, and stomach swelling. (1)

Foods high in lactose are those which contain milk. These include ice-cream, milk puddings, hot chocolate, egg nog, macaroni and cheese, yogurt, pancakes, milk chocolate, cottage cheese, and mashed potatoes. (2) Below are the top 10 foods highest in lactose.
