> lacks the [...] bioavailability of real animal protein

I never understood this argument: what's the problem with consuming proportionately more to make up for the reduction?

I'm not rushing to demand IV tylenol because its oral bioavailability is only 80%-90%, which is around the "loss" we're talking for plant vs animal protein on average. And the ultraprocessing should improve plant's profile here.

Eating raw Miso a few times a month can move one's biome to get more plant protein digested per gram than even from egg whites. So the issue with protein is somewhat overhyped. The main potential shortfalls in the vegan diet are vitamins B-12, D & K.

Because the macros suck. If you’re trying to hit certain protein / carb / fat ratios, eating more of the “protein” means eating a lot more carbs and fat too, which often isn’t the goal.

Your analogy is not accurate, it would be more like waking up in pain in the middle of the night after a bad injury, and taking t3s with codeine+ caffeine, and wanting more codeine without wanting the added caffeine.

  • if you have only fixed-ratio food options, sure, but otherwise, no.

    > and taking t3s with codeine+ caffeine, and wanting more codeine without wanting the added caffeine.

    that's what tylenol #4s are for, double the codeine, none the caffeine. Take half a t#4 and half of a regular standard tylenol = T#3 without the codeine.

On top of that, there seems to be a pervasive misconception of the effectiveness of plant vs animal-based protein on things like muscle growth. Older studies showed that plant-based proteins had lower digestibility scores via metrics like PDCAAS. In turn, people interpolated that muscle growth would be lower. Some early studies comparing the two protein sources on muscle synthesis didn't do gram-for-gram comparisons and that increased the misconception. Newer studies are showing that, if you match the protein amount at or above the 1-1.6 g/kg for muscle growth, you will get the same level of muscle growth.

I feel like it'll take another 5 years for this "bio-availability" myth to die out.
