What are your thoughts on trials like this one that find when you look at the protein-related outcome we presumably care most about, muscle growth and strength, there are no significant differences between vegans and omnivores undergoing resistance training when matched for protein?

I don’t think working out twice a week for 12 weeks is enough to note any real difference in your one rep max leg press. I’d be interested to see a longer form study with a workout regime designed for muscle growth.

My point is that the leucine content generally is lower in plants and that's a limiting factor. Vegetables have a less ideal amino acid profile. As long as you get enough leucine you're good when it comes to muscle building.

Regarding the study you linked: if you look closer at the nutrient composition the protein intake and amino acid intake is roughly equal between the groups but the vegan group has a higher carb intake, and as we age we all become more or less carb intolerant and that's one of many drawbacks of a pure vegan diet. Other drawbacks are lack of micro nutrients that need to be taken through supplements unless extreme care is taken, and for practical reasons it's not easy to achieve compared with an omnivore diet.
