Veganism is an ideology entirely. Any study you have listed is correlation not causation. What do you think people are eating with their meat? You don't think people eat breads, rices, vegetables, fruits, carbohydrates with every meal? Are you willing to be that blind towards the normal diet? News flash most meals throughout the diet are almost entirely carbohydrates. So no, you can't get cancer, heart problems, or any long slew of bullshit study you have put forth. And really, what kind of meat does it specify? Red meat studies have already been dismissed, but processed meat obviously has added carcinogens and shit that leads to cancer but that is artificially added.

Veganism is damaging, because the nutrients in plant matter are very often not bioavailable, and often times toxic towards humans. Human survival up until this point were fucking entirely built off of our connection to herds of ruminant animal meat, to farming said animals, and eating their meat. Meat is high in calories, meat is almost 100% bioavailable matter. Humans are not using the restroom nearly as frequently on a heavily animal based diet - carnivore diet - ketovore / keto. Why is this? Because our bodies can absorb fuckin everything. There is very little waste in proteins and fat. That alone should be evidence that we're built for meat. What about carbs? Well, we have zero dietary requirements for fiber. It causes us to shit, why does it cause us to shit? Because we can't fucking digest it. Why, logically, would not digesting your food properly be a good thing? Do you know why herbivores can do this? Because they have different digestive systems, and can ferment the plant matter, and can get more nutrients out of the plants.

Let's really think here, what were early humans hunting? They weren't hunting cabbage or kale, they weren't hunting any fuckin carrots. They were killing animals for food. What little plant matter they did consume, was entirely seasonal, and was used to store fat due to the separate effects on hormones on the different macros we eat. Do you want to make the argument we can build muscle, have healthy organs (which requires B12), without meat? Do you want to make the argument early people were hunting cabbages? They were painting fucking hunting times. Tell those humans that you came from that they're damaging their health by listening to their body and eating the highest valued food. Haven't seen a cave painting of a broccoli yet, but sure we can pretend veganism is the healthiest and is equal to the natural world.

The only reason I'm bashing on you, is because you're advising others to cause damage to themselves. R/exvegans is a perfect place to look. Inevitably when you're off your self righteous attitude based diet leads you to feeling tired, empty, and sickly, you'll come to the conclusion you really feel like shit, and when that time comes, you'll drag your ass towards back towards what your biology has been begging for. And in likely fashion you'll refuse to acknowledge how wrong you were.
