It's funny you are worried about the impact of vegan alternatives and not, say, sugars, alcohol, overly fatty or salty foods, too much bad quality meat raised with hormones etc. It's almost like you have a bias against the vegan alternative..

Edit: ok so I was not terribly constructive with this comment, so happy to elaborate. I'm pretty tired of this argument against vegan meat. The nutritional values of vegan meat are not that bad even in the worst case in relation to everything else that is in the market - it's a non issue at best. What I believe the commenters parroting this line really want to say is that they like meat and need a reason not to eat/support the alternatives.

Arguments against eating meat are orders of magnitude heavier than against vegan meat.
