You talked about a DIAAS (digestable indispensable amino acid score!) - you are my favorite person today.
Actually, I didn’t. I just realized, that I linked to PDCAAS, which is a slightly different method. But it didn’t really matter, as I just wanted to illustrate the concept. And I’m not too involved in the topic. I don’t know what you’re doing, that you’re whipping up tables about this stuff, but I’m just a layperson with a little knowledge about nutrition.
Allow me a few remarks though:
you’re referencing prepared meat, but raw tofu?
In my experience, tofu is usually also prepared in some way, and with most preparations, it looses quite a bit of water content.
We don’t have to rely on mostly unprocessed plant food. There’s stuff like texturized vegetable protein, that delievers a more concentrated source.
While a table like this gives a good overview and reference, it’s easy to miss the fact, that we usually don’t get our protein from a single source. As I mentioned in my last comment, combining different sources can be a good way to enhance the overall protein quality.
To reflect that, we’d need DIAAS data for prepared dishes, meal plans or a whole diet.
Can you even use DIAAS to calculate an amount of single protein source food, that you’d have to eat like that? I don’t know if it scales that way, and even if it did, for an incomplete protein source, you’d end up with a lot of excess for the abundant amino acids in that protein source, which I suspect would have to be excreted and I don’t know how your kidneys like that.
That table would really benefit from adding references to clarify what you base your assumptions on and where you get your data from.
But I think none of this is all that relevant for the underlying topic in this thread.
Well written! Yes combinations are a great way to complete the liebig amino acid barrel - here is a fun tool that helps do this https://www.diaas-calculator.com/ - but DIAAS cannot be “calculated”, we can guess by adding up amino acids in isolation, but you don’t get a real DIAAS reading unless you feed the combination to a pig then actually measure the amino acid absorption.
