To those wondering why lab-grown meat instead of going vegan: People are driven by incentives. People like meat, so instead of asking them to stop eating meat, which most won't do, make it a better option that fits with whatever the asker's goals are. In this case, you'd want people to care about animals or decrease environmental effects, so the way to do that while also considering people's incentives of loving meat…
It’s even simpler than that. There are some people who simply don’t function as well when they don’t eat meat. “But I’m vegan and I do just fine, in fact it I feel better then when I was eating meat”. I don’t doubt you, but I also don’t doubt the ex-vegans who tried and tried, but just felt awful and tired until they reintroduced meat. Different people have different metabolisms, and some people just can’t properly d…
This review debunks the "bioavailability" and "quality" claims quite easily.
"bioavailability" (pdcaas diaas) is a contrived measure of protein source completeness made up to characterize protein issues of starving humans. It was also calibrated on rats and pigs, not humans. The "complete protein" misinformation is everywhere. Even on Wikipedia https://en.wikipedia.org/wiki/Complete_protein (edit: now I see that someone recently changed the statement to "adequate proportion" while previously it was just referencing that it contains all 9 essential amino acids).
All plants contain all essential amino acids, including green grass. Completeness in case of no starvation does not mean a thing. If you are eating 3000kcal of wheat every day, protein is no longer a worry, despite wheat having a 25% made-up bioavailability measure that was deduced by checking what happens to nitrogen in a live pig.
The protein "concentration" is just not true. Chicken breast does not have 90g of protein in 100g of chicken breast. 35g of protein in 100g of raw soybean. You will have to find a really rare steak of 100g to top that.
> Many ex-vegans have been consistently anemic, even while taking iron supplements, until they re-introduced meat.
This is not at all the conclusion of peer reviewed articles. Increased occurrence of nutrient deficiencies in vegan populations does not exist. Some people get deficiencies on any diet, and this is also the case for diets that have low-calorie high-volume foods like plants. Nothing special about that. People need to eat more volume but rarely do so. Similarly, they need to eat more calories. Talking about micronutrients in a world with no starvation is unnecessary. If you're eating a variety of plants, enough calories, it is certain you are consuming all of the necessary nutrients and protein. If you want to do powerlifting, marathon running, you will need to adjust your diet, whatever diet it is.
