I don't know if this is just a phase but DD seems determined to start following a vegan diet because she's horrified by the way animals are treated (be it for meat or dairy). I'd be ok if she opted for vegetarianism but I'm concerned about her not getting enough calcium, protein etc in a vegan diet.
Has anyone else experienced this or are vegan themselves? Whilst I do share some of her concerns about animal welfare and have been sympathetic, I've also pointed out that there might be health implications.
