Nutrition
CSoy protein versus animal protein
Messina M, Lynch H, Dickinson JM, Reed KE · 2018 · International Journal of Sport Nutrition and Exercise Metabolism 28(6):674-685
REZA evidence rating C: Interpret with caution
Methodology
Systematic review with meta-analysis
Findings
No difference between soy protein and animal protein for muscle mass and strength with strength training.
Conflict of interest
The first author has known ties to the soy industry. That doesn't automatically make the conclusion wrong, but it is worth noting.
Practical conclusion for REZA
Included with that caveat, as an example of how REZA handles conflicts of interest. The conclusion aligns with the animal-versus-plant-protein study, which carries no comparable interest.
