The study I cited was of mammals. We aren't going to learn anything useful from the lifestyle of cold-blooded reptiles. For one, their metabolic rate is much lower.
Likewise comparing ourselves to obligate carnivores, or obligate herbivores is also less useful. Ideally you'd want omnivores that for one reason or another excluded meat from the diet, or did not. Right?
Not really. The key question is whether meat is carcinogenic or not. If you eat less of it, sure it will be less carcinogenic, but it won't be suddenly good for you.
There seems to be a lot of people who want to eat meat and also deny that it has various adverse health effects. The evidence is pretty clear, that's all I'm saying. What one does with that information is up to the individual. I don't do anything with it.
but you can't blanket say meat is carcinogenic. If we acknowledge that meat has no link to cancer in alligators or sharks, then we need to question if it is because of animal, the meat, or both. Likewise, if mountain lions have higher rates of cancer than deer, is it the animal or the food? Likewise deer are eating acorns which are very high in antioxidants. So its another variable. Do mountain lions have higher cancer rates than a wild hog? That is an interesting question. As far as my bias from what I want to do. I want to eat ice cream and drink scotch all day, but I won't argue either are healthy. Alcohol is generally listed second after tobacco as a cause for cancer in humans. I really just don't think the link between meat and health is well established in humans, or even if it is the same across human variation.
