The gene in humans for digesting lactose is SNP C/T13910. Until only about 10,000 years ago humans digested milk until about age 4 or5. With the domestication of dairy producing animals, this has changed gene SNP C/T13910. Now, about 86% of Northern European peoples have evolved life long dairy digestion. As opposed to one-third of Southern Europeans with life long lactose digestion and in the Far East, the gene is non-existent. So really the only thing people with this capability have in common is cows and other dairy producing animals.
So, newly lactose intolerant folks, welcome to the club of the 14% who may not have developed this gene mutation.

I'm not certain if I'm officially lactose intolerant or not, but I'm perfectly happy to avoid dairy for the sake of the cows, my weight, and my digestion.
ReplyDeleteI love dairy, but dairy does no love me :(
ReplyDeletedairy is a funny and strange thing. sometimes i think about cutting it out completely, but instead i just try to limit it a little... i wonder if i'll ever develop an intolerance...that's another strange thing that can happen
ReplyDeleteI don't know about the gene stuff -I just hate the taste! Unless, of course, it's chocolate.
