Symptoms include abdominal gas, bloating, nausea, cramping and sometimes diarrhea. During digestion, lactose needs to be broken down into smaller units of sugar by an enzyme named lactase. This occurs in the small intestine which then absorbs the sugars into the bloodstream to be used by the body for energy. When a person does not make enough of lactase, they cannot digest lactose. My first response to this question is no, at least not because of lactose intolerance.
Milk products are the main source of calcium, which is critical to developing healthy bones.
Without sufficient calcium, especially during the growing years, a condition called osteoporosis may result. This is characterized by porous, spongy bone that is much weaker than dense, healthy bone. Hip fractures in later life are a common problem associated with osteoporosis. It is recommended that children and young adults aged 9 to 24 get 1300 to 1500 mg. of calcium every day. Remember that it is also important to engage in weight-bearing exercise 3 to 4 times a week to build strong bones.
