You talked about a DIAAS (digestable indispensable amino acid score!) - you are my favorite person today.
But let's contextualize plant proteins by how much food you need to eat, an 68kg adult needs about 110g of protein per day - Eating steak that is 350g of food, eating tofu is 650g of food, lentils is 1600g of food.
As the amount of plant based protein increases so does carbohydrate burden - a significant factor people need to be aware of, as most (94%) western adults have impaired metabolism and thus impaired insulin sensitivity - increased carbohydrate loads need to be carefully considered in their diet.
As a contrived example 1.6kg of lentils is 1900 calories.
graph i whipped up last week
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.
Why are you pretending that every human is a bodybuilder? Your stated protein needs are way above what science says is actually needed
That is a fun turn of phrase
There isn't one person who's opinions encompass "science says" - multiple public health bodies recommend a 1.1-1.6g/kg/day protein intake.
