While klling an animal for food is sure destructive for the animal, it is constructive for the humanity. It allows us to get all those proteins "for free" instead of producing them ourselves from plants like herbivores do and invest the saved energy in our intelligence to create beautiful and complex things. Whereas copulating with an animal is pure destruction. It harms the living being and leads to no babies and no emotional bond strengthening (contrary to human sex).
Eating animal is still a contradiction, because destruction is there. So I think this problem does need to be somehow overcome. But at least it's outweighed by its positive effects, unlike zoophilia.
We literally grow food to feed to animals. And then we have to spend time hearding the animals moving. Slaughtering is a decently evolved process (I think). They don't give us the meet for free, we have to put effort to take it.
This bit is nonsense. I'll give you a point for meat consumption being an easy source of protein that allowed for some developments during the evolution of humans, that are unlikely to have happened without it. But that is more a question of availability than nutritious properties. In todays surplus society, where we have industrialized agriculture and optimized crops, there is abundant access to plant protein.
And meat is not a unique source of protein either. First of all, you don't even have to eat meat to obtain animal protein. Eggs and dairy have it too. And when it comes to the constitution of protein, eggs were even considered the gold standard for a long time.
Read the following wikipedia article to learn more: https://en.wikipedia.org/wiki/Protein_digestibility_corrected_amino_acid_score
The listed examples should be interesting to you.
While meats are indeed easily digestable and contain useful protein for the human body, so do many plant sources. Soy protein is even on par with eggs, while meats don't reach the same score.
And of course we usually don't eat a single source of protein, and combining different sources, their amino acid profiles can complement each other to form a complete source of protein.
This might've been a bit of a ramble on a side-note when it comes to discussing the ethics of fucking animals, but I'm sure the discussion benefits from getting the facts straight.
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.
