The Study
Plant-based protein: A multi-nutritional sustainable alternative to animal foods and their structure, functions, and relationship: A review.
This study is like a teacher summarizing what other scientists have said about plant proteins — it doesn’t do any new experiments. So it can tell you what people think, but it can’t prove that eating more plants will make you healthier.
