Not entirely true only eggs have the perfect amino acid profile. Meat yields about 80% and yes peas do about 70% but as I already mentioned people don't just consume one thing. You have to account everything you eat in one day. Peas combined with a grain will fetch you a higher bioavailability than meat.

I recommend looking up basic nutrition science

You can just Google the amino acid content of each individual food. Or use a food tracker like cronometer. It shows you the amino acids you get and your daily need. Nutrition content isn't that hard to filter if you avoid websites and go straight for papers.

This video is in German but you can check out the referenced papers in the discription. https://youtu.be/_IRjZpmPZ-Y

The guy is a nutrition scientist and has a lot of stuff on all different kind of topics.

That's not how this works. We don't absorb protein. We take protein and break it down into amino acids. Amino acids are the same no matter the source. What matters is the distribution of amino acids in food. Combining grains and lentils for example gives you a better bioavailability than meat. There is no such thing as protein quality. We use amino acids and they are all the same.

It's because the DIAAS is completely useless https://pubmed.ncbi.nlm.nih.gov/33409931/

Bioavailability of foods can't be considered per food be außer humans eat more than one thing. Combining lentils with grains for example gives you a higher bioavailability than meat.

The perfect combination of foods are legumes with grains. This gives you a higher bioavailability than meat. All over the world people combine lentils with grains.
