There are amino acids you can't get from plant protein.
- thehappypm 5y agoFrom first principles, how is this possible? Food animals get their amino acids from eating plants.
- shafyy 5y agoOf course there are amino acids that don't exist in plants, but they are not essential (i.e. can be synthesized in the human body and don't need to be taken from external sources). From first principles, it's possible because e.g. cows could make amino acids that are not found in plants, but those are not essential (I don't know if cows make any non essential amino acids that are not found in plants, this is just an example)
- insaneirish 5y agoClearly plants get them from eating animals.
- tofukid 5y agoAll essential amino acids are found in plants, and some plant proteins (soy or hemp for example) contain all the essentials in a single protein.
- shafyy 5y agoI don't know why you're being downvoted, this is true.
- Leherenn 5y agoIs it in a "reasonable" amount? As in, is the concentration comparable?
- shafyy 5y agoYes, there is an index called the Protein Digestibility Corrected Amino Acid Score which shows exactly this: https://en.wikipedia.org/wiki/Protein_Digestibility_Corrected_Amino_Acid_Score https://en.wikipedia.org/wiki/Protein_Digestibility_Correcte...

- shafyy 5y agoNo, all essential amino acids can be found in plants. We have a long way to go if even people here on HN (which I would consider more educated than the average person) gets something as basic as this about nutrition wrong.
