The lactose intolerance mutation is not race specific: 15% of Caucasians, 75%of African Americans and 90% of Asian Americans are lactose intolerant, this means that for every race there reasonably large exception and a race wide diet is not adequate for the individual. If your Asian and are not lactose intolerant should you still not drink milk? No of course not.
for the first time, wellcooked, I have to disagree with you.
No, if you are Asain, and not lactose intolerant, then there is no reason to not drink milk. However, if you didn't know if you were lactose intolerant or not, then by following your own numbers, there is a statistically better chance that by being of Asian decent, you are lactose intolerant. It doesn't mean you are, it means that until you know one way or the other, it may be worth assuming you are, given the chances. this of course, depends on the effects of the intolerance in question. Were we talking about nut allergies, then any chance you may be allergic could be a life-threatening chance.
Not all people are allergic to Poison Ivy, but untill you know for sure, I wouldn't recommend rolling around in it. I'd recommend assuming that you are allergic, given your genetic history, and then slowly test things to see how things are specifically for you. In a safe and controlled manner.
Ancestry doesn't matter humans don't deviate enough genetically to warrant any change of diet based off race.
you contradict yourself with your above quote, don't you? if only 15% of Caucasians are lactose intolerent, then 15% of Caucasians should not drink milk. then if 90% of asians are lactose intolerent, then 90% shouldn't drink milk. That's a 80% difference in diet recomendation based on race alone!
The Native American body recieves a European diet in a significantly different manner than a European does. Take the obisity levels of the NA population, and compare it to the caucasian population on the same diet, and you will find a significant difference, seemingly based on Race alone.
Now, I will concede that the human body is quite good at adapting to the diet it is given. However, considering the western world, the world with the least amount of inherited ancestrial diet, is also the culture with the highest incidents of cancer, heart attack, non-microbial intestinal illness, etc, I'd say we should assume something's up until we know for sure one way or the other. I'm not suggesting we only eat what is statistically best for you ancestry; I'm suggesting that until you do your own reaserch, and know for sure what you body requires for optimal output, following the percentages for your ancestry will give you a "most likely" starting point.
