No matter what they say I will still eat meat. I have cut down the amount of red meat and eat a lot of chicken, turkey, pork and even deer more than cattle. I will still eat red meat now and then but for the most part it is more fowl that I tend to eat when consuming meat.
For the vast majority of people, meat is no more a cancer risk than the sun is. They both technically are, but I sure as heck am going to enjoy a burger outside from time to time.
Not my field, but as I understand it, Polyoma viruses are only a notable threat to the immunocompromised.
My dad ate meat until he died at the age of 93 and in full control of all his faculties. My grandfather was 95... We think. My genes seem to be okay with it. With the way medicine is going I expect I'll live to about 125! ;).
I have IBS, so there is a lot of things I can't have. I eat meat, because I enjoy it, but its also protein which is something I need to get a lot of. I don't eat meat every day. I think it comes down to the individual's own constitution - I was a vegetarian for three years and was hungry for most of the time and if I didn't go back to eating meat, I would have been on iron tablets for the rest of my life, which is something I did not want to do. I have many vegan and vege friends and they respect my decision to eat me as I respect theirs for not to.
Yes everyone makes their own choices for eating meat or not eating meat. Many people need it for the protein and I also know there are other ways to get protein but each person does their own method and if it works for them do it.
Scientists work to develop heat-resistant 'cow of the future'. More than half the cattle in the world live in hot and humid environments, including about 40 percent of beef cows in the United States. By using genomic tools, researchers aim to produce an animal with superior ability to adapt to hot living conditions and produce top-quality beef. Source 7p.
