The RDA for protein was based on high-quality protein sources, and lower protein intake necessitates a greater proportion from animal-based sources.

“the RDA which is the minimum to prevent deficiencies was also based on high quality protein are plant-based friends that means uh the average adult intake of protein is around 68 grams for women and maybe 90 grams for men and that is not all from high quality proteins there's also there was also a proof of concept I think it was out of I think it was a French group that showed that the lower the protein intake was across the board the higher the amount needed to come from animal- based sources”
