Other forms: lactose intolerants
If you're lactose intolerant, your body has a hard time digesting a sugar that's found in milk. You may want to to order the vegan pizza if you're lactose intolerant!
People who can eat dairy products like ice cream and cottage cheese with no problem have digestive systems that make plenty of lactase, an enzyme that breaks down the sugar called lactose. Being lactose intolerant means that your small intestine doesn't produce enough lactase; eating a bagel with cream cheese or drinking chocolate milk can give you a terrible stomach ache. Lactose has a Latin root, lac, or "milk."
