Can Lactose intolerant people have lactic acid?

No, people who are lactose intolerant cannot have lactic acid. Lactose intolerance is a condition in which the body is unable to digest lactose, a sugar found in milk and other dairy products. Lactic acid is produced when lactose is broken down, so people who are lactose intolerant cannot consume foods that contain lactic acid. Foods that contain lactic acid include yogurt, cheese, sour cream, and buttermilk.
