Sure, my point isn't to convince anyone to quit meat. I eat fish anyway. But as this is a thread about veganism and there have been questions about non-animal 'protein sources' I'm just showing that it's a lot easier to get protein on a vegan diet, than most people believe.

I don't meet my calorie requirements by consuming 'Oreos', 'potato chips' and fizzy drinks though, which are every bit as 'vegan' as kale and lentils but very high in calories from fat and sugar and low in other essential nutrients. Junk food vegans do exist - folk who really do live on top ramen noodles, oreos and chips - and they don't tend to do that well.

If I was eating sweets and snacks all day instead of a diet comprised of predominantly of vegetables, wholegrains and pulses (legumes) in a variety of combinations, I'd be much less likely to get all the nutrients - including amino acids - that I need without supplementation.
