@jack412, I meant to say don't look at the diet bit at the end of that article, I think I must have edited it out. That one was just for the ethnic distribution of the alleles. The long article does have some evidenced based diet/lifestyle comments at the end.
You can't though tell what you are without having your DNA tested and unfortunately that costs (123andme isn't too expensive for the testing but the postage charges from Europe are horrendous and I suspect it's even more from Australia)
