If i'm not lactose intolerant, is lactose good for me?

Sort of...: Lactose, also called "milk sugar" is the main carbohydrate found in milk. Even though it's a sugar & provides calories, its flavor is somewhat bland so it is used extensively by the pharmaceutical industry as a filler in pills. Lactose makes up between 2-8% of cow's milk by weight, so any food that contains milk will have lactose as well. Purified lactose is a high-calorie additive in some diets.

Lactose: Lactose is a sugar carbohydrate found in dairy products that our body breaks down to use for energy and store for future energy needs.
