• People who have an intolerance experience physical pain, so a tolerance evolved to avoid that.
Lactose tolerance allows people to enjoy a wide variety of food, including milk, butter, ice cream, and cheese.
Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
