Processed meat with all the nitrates, salt and fake ingredients sure, I’ll agree they aren’t good for anyone. And that much of what we eat is unnatural as well.Its important to do research and take supplements to ensure good health on a plant based diet, but it is possible to thrive on the diet. The first time I went vegan, I struggled because I didnt know what to eat. This time Ive researched, and there are plenty of healthy, non genetically modified formed of plant based protein. That is interesting! Though soy isn't something I personally eat a lot of, really.
Yes, we are naturally omnivores, yet modern research shows us that processed meat causes cancer, and red meats can cause cancer also. In moderation, one can live in okay health on a meat diet, but I will always believe plant based to be healthier, as long as it's done properly, gradually and carefully.
Same goes for dairy, that's a big one. 70% of people cant even digest it properly. Plenty of what we eat, and how we eat it, is unnatural.
