I mean we don't need animal proteins for a healthy human diet...
B12s and similar are a bigger issue IIRC. Plants have the exact same proteins all life does, just not necessarily in the right amino acid proportions for humans. If you're not eating all one staple like a peasant you're probably not going to get seriously protein deficient, although it's harder to get enough to build muscle.
I've been vegan for years and will tell you it's incredibly easy to get the amount of protein in. Plus like with an omni diet most packaged foods are fortified for vitamins.
Good to know. I've been ovo-lacto so I've never worried about it.
From what I've seen veganism isn't so good for actually bodybuilding, but let's be honest, the exercise is the bigger barrier for 99% of people. Maintaining a flabby Westerner body isn't biologically hard.
100g of wheat gluten is almost 80g of protein. Which easily provides the amino-acids most legumes have in lower concentrations. Besides seitan which is very easy to make from wheat gluten, tofu, tempeh and many other plant based (and really easy and cheap to prepare on your own, in large quantities and store in the freezer, I have a drawer in mine full of them) foods in some traditions that are even low in carb content for people with insulin resistance. Or just low in calories so you can cook them whichever way you want with whatever else you want to add to your food. It's not really hard to actually do it.
Being "not flabby" has more to do with your understanding of how insulin works on the body than it has with anything else, even activity levels. Especially in western societies. And its pretty damn hard to think properly about your food, even though its scientifically clear those in charge are pushing shitty guidelines to the people. For example, as you can see here :
Some don't need the carbs though and that's not as easy as getting the proper amount and kind of aminoacids when going completely plant based. If you have the time you might find this interesting.. The number of people that have a messed up body when it comes to carbs, is beyond impressive.
I am commenting on the "healthy" aspect. Healthy, sometimes is not just about adequate.

And what does this have to do with my previous point?
Basically the study found that previous research on TMA's (which are abundous in animal protein) saying they're harmful to humans, may actually be wrong, and that they're in fact beneficial to our health. (edit 2: due to rapid bilophia production in the microbiome, which converts it to DMA?)
I'm not a microbiologist though, and I hope someone with background could expand this into an ELI5.
Edit: If you scroll down on the page, you can find a figure (FIG 1) which gives a more easy to understand view on the study and the impacts animal proteins were found to have.
