I think the actual genetic factors for lactose intolerance are very rare. It probably has more to do with gut flora and consumption. I am slightly intolerant and have symptoms if I stuff myself with raw milk. Other than that it is no problem. I have a friend with the genetic condition and even he drinks milk. He does get problem quickly, but not if he drinks coffee with some milk or yogurt. I think all people develop an intolerance with age naturally, but people that consume much milk will have that process slowed down. I think the genetic factors can just accelerate the process that is responsible to induce intolerance.

> I think the actual genetic factors for lactose intolerance are very rare. It probably has more to do with gut flora and consumption. Not really, lactose is basically converted straight into glucose by lactase, and if you don't produce lactase the lactose is going to be digested by a variety of bacteria and turned into a whole host of products (some of them usable by the body) but mostly gas. There isn't really a way to avoid that, even though gut flora can be more or less efficient and allow non-lactase-producers to mostly digest milk, it's never as efficient as using lactase. > I think all people develop an intolerance with age naturally No, it's a well-researched thing, some populations of humans keep producing lactase after their childhood and some don't. It's not related to the milk consumption of an individual, either.

  There is fats in milk, the energy is not exclusively lactose.
