Genuine question, what benefits do you mean? On the health side - since I went vegan + aiming for whole food plant-based, I've been the healthiest I've ever been. I wasn't even anticipating it, but I've lost a great amount of weight without trying and have more energy than ever. Definitely has cemented the switch as one of the best life decisions I've ever made.

I think the book How Not To Die by Dr. Michael Greger explains really well why. It discusses how animal-derived foods straight up are not good for you nutritionally. It also explains the health benefits of various plant-based foods in preventing different illnesses and supporting your immune system. I recommend it.
