In addition much of the human Plant based food supply has problems with agricultural contaminants being ingested by humans, such as glyphosates which some people are intolerant of.
The thing with DIAAS is that it’s hardly relevant and I feel like it’s played up by misinformation from the meat industry.
Let’s say you only eat red lentils for your proteins, which according to that DIAAS calculator has only 59% of the SAA compared to the amino acid distribution that your body needs. Then the solution is simply to eat twice as many red lentils to get to 118% SAA. Your body needs a certain amount of each amino acid, but if you give it more, it can work with that perfectly fine.
DIAAS is only relevant, if you eat close to the minimum amount of protein that your body needs in general, which is hard to do. For example, in the US, the Recommended Dietary Allowance is at 0.8 grams protein per kilogram of body weight. Which is a one-size-fits-all number they chose to cover the necessary intake even for athletic and pregnant folks. The majority of people need less protein than that. And yet, according to this site the average American eats 1.6 times as much.
Mostly its a concern about the DIAAS of the protein source. https://en.wikipedia.org/wiki/Digestible_Indispensable_Amino_Acid_Score There is a reference of published DIAAS for different sources here https://www.diaas-calculator.com/
Basically a function of how much usable protein a human gets from different sources. i.e. Liberg’s Barrel of Amino Acids https://www.researchgate.net/figure/The-Liebig-barrel-illustrates-the-limitation-of-protein-synthesis-due-to-the-lack-of-an_fig20_333729916
PBF Protein sources come attached to plant byproducts that some people can’t tolerate very well, lectins, oxalates, etc https://www.who.int/news-room/fact-sheets/detail/natural-toxins-in-food
