You stopped ageing... lol sure... Don't know if I can take you serious or not. Anyway, I agree to an extent, eating too much meat isn't healthy, but that's the case with a lot of things. About milk, it didn't use to be ''natural'', but humans (with the exception of some African tribes) have developed a resistance against lactose, and it is completely fine to drink, but again, not too much. Meat on the other hand has always been part of the human diet.

Again, did you read my post? Different types of food have different effects on our body, but acidity doesn't matter.

It depends on how the research is conducted. I've seen and read plenty of half-arsed research papers in my life, but the things that's usually worse is the conclusions people draw. The raw data itself is usually interpreted wrongly. A lot of people tend to confuse causation and correlation. I can conduct a research where I follow 5,000 people that consume ''processed'' foods and 5,000 people that are on a ''natural'' diet (or even vegetarians if you want). I'm almost certain that the results will show that group A, the one that consumes relatively more ''processed'' foods are more likely to develop cancer than group B. However that isn't proof that ''processed'' foods cause cancer. There's usually a lot more going on. It's just a correlation, not a causation. If you're very concious about what you eat, you probably don't smoke and you probably work out more as well; thus you're more likely living a healthier life than group A, thus explaining why group A is more prone to develop cancer than group B, not necesarily because they have a more unhealthy diet, but because their entire lifestyle is likely less healthy. But still, you need to find what actually causes the cancer and how it causes cancer.

If you fry (burn) them with too much heat, then yes. But if you burn veggies in the same way, they are carcinogenic aswell. Also, something like sunflower oil promotes cancer by nature, just like olive oil that's heated too much. Also, cancer cell feed on carbohydrates, which means LCHF could help you fight cancer (apparently so does vitamin D).

No all animals matter, i don't pick and choose which ones are more important. I don't partake in speciesism. I just mentioned those animals because of the topic at hand. Those are the main ones we breed, torture, and kill by billions every year and they are most docile. All of those animals you listed kill out of necessity(food) or self defense. Also the scale of those situations doesn't even compare to what we do to them. Pigs mean as hell? lol Maybe abused pigs. Pigs are very docile and extremely smart, smarter than most breeds of dogs, but the majority of bacon eaters lose their shit when people talk about eating dogs. Reality is very few animals will go out of their way to injure or kill another animal without feeling threatened or for necessity due to their biological make up.  Humans were not designed to eat meat, and we are healthier without it. We haven't evolved to meat, which is why we still cook pretty much all meat to make it "safe".
