How does the mutation that results in lactose tolerance affect people?

The mutation that results in lactose intolerance prevents people from consuming milk and its derivatives.

Explanation:

Lactose intolerance is a deficiency in the production of the enzyme lactase, responsible for digesting the sugar present in milk and dairy products. This problem, which affects more and more people, imposes limitations on diet and when the diet is not strictly followed and dairy foods are ingested, some reactions happen - the unpleasant symptoms of lactose intolerance.

In this disease, the amount of enzyme produced may vary from organism to organism, and in some cases it is completely nil. This results in various levels of intolerance and the less lactase is synthesized, the more intense the symptoms of milk sugar consumption.
