I feel this way, too. Contrary to popular belief, humans were not made to consume or digest meat. Literally all of the beans, lentils, vegetables, fruit, meat and dairy alternatives etc., contain all of the necessary protein and calcium. In fact, their protein and calcium content is much higher than that of animal protein and dairy products, while simultaneously containing less fat, sugar, etc. and being so much easier on the GI tract. I've also experienced the "oh, I could never ever do that," and the "I would be vegan, but I love and need cheese." Well, no. You could definitely do it. And you don't NEED these things. You want these things. Which is completely fine! I've been a vegan for almost 3 years now. However, I don't force my opinions upon anyone. No one in my family follows a vegan diet and very few friends of mine are even vegetarian or have eliminated red meat at the least. In fact, my little brother is an athlete who was recently sponsored by the whey protein company (products with casein), and until a year and a half ago he'd make the protein comments to me, call me frail, etc. ask me how I would continue surviving without bacon, and the like. I never tried to change his mind on any of it by degrading a carnivorous diet, I just explained my preference and allowed his. He one day came to me to let me know how much he had recently learned and respected about veganism. Many of the athletes he had been competing with were vegan, as well as famous one he'd been looking up to. He realized just how much health, talent, and athleticism they brought to the table and just how much the protein and sufficient nutrients argument had become invalid. (Maybe he's just brown nosing so I'll make him another batch of buffalo chickpea dip
😉) Sure, deficiencies are possible and common...but this is due to the personal characteristics of one's diet. If you do not include a well-balanced array of nutrients in your diet, you will lack in some area(s). This is the same for carnivorous individuals. Everyone is different and explaining the lifestyle(s) can only do so much. It's got to be a personal interest or realization. But it's nice to know you're on here, too!
