Sweeping statement there, laddergoat.
I don't plan to try to disprove your statement, so I'll let it slide with healthy skepticism.
You know what? I've not read any of the evidence either way, and if i did, it wouldn't necessarily mean a thing to me. Evidence that a meat/dairy diet is better for me isn't going to convince me to eat it, any more than 'evidence' on some alleged dangers of soy protien. Remember, I take NO suppliments of any kind, and try to rely on a balanced diet, which at times means a bit more work and consideration of what I eat, but not as much as you would think.
I don't choose to be vegan for health reasons, I choose it because I oppose the killing and mistreatment of 'animals' (in all their forms), and can live a perfectly healtly life without supporting the industry I oppose, with a clear conscience (look up 'cognitive dissonance').
I'm a pretty science minded guy, but I don't approach my diet scientifically. I don't blindly ignore advice that a vegan diet presents possible health risks, instead, I try to counter those risks.
Something will eventually kill me, maybe sooner than an omnivore diet would, maybe later. I choose to live in a way that makes me happy and content. Not better, not worse, just different that most. 'Bulking up' is the last thing from my mind, but then, i'm and old man now. Soy protien may or may not be the best choice of poison for bodybuilders...meh, you do what works for you.
I rode XC/trails from 5.30-8.30am this morning, had a shower then rode to work 15kms. I couldn't do that on my diet (or any diet), without putting good fuel in the tank. I'm fitter now than I was 20 years ago, but only because I exercise more and eat more sensibly (arguably) than I did 20 years ago, not because I'm a vegan. I only try to stay healthy and fit enough to enjoy my riding, and keep up with my kids as they grow up....and so far, i'm right on track with that goal :very_drunk:
