B12 and vegan supply of omega 3 fat is still a concern, especially for children and infants.

For example, if you use plant sources for your fat supply of DHA, you'd have to ingest enough ALA to make most people sick. So supplements are necessary for health, especially in children (vegan algae based supplements do exist).

Another question is soy reliance. Last I checked, we can reasonably assume that a "normal" amount of soy in a diet is a non issue. However, results during pregnancy and childhood are apparently lacking, and studies in rats show potential problems [1].

"Further investigation is needed before a firm conclusion can be drawn. In the meantime, caution would suggest that perinatal phyto-oestrogen exposure, such as that found in infants feeding on soy-based formula, should be avoided." [2]

Just to be clear here: I am a vegetarian. However, I never went full vegan because I think it does require a very mindful and conscious handling of nutrition - and a lot more research [3]

By extension, I do not think it is appropriate as a recommendation for the general public at this stage.

So we need research and educational efforts into plant based nutrition instead of pumping all tax money into marketing and subsidies for the meat and dairy industry. Big surprise.

I’m raising two perfectly healthy vegan kids. They are above average on most factors that matter and continue to amaze people around us when we tell them they are vegan.

There is so much misinformation out there, and extrapolating from cases where parents fuck up isn’t helpful. All kinds of people fuck up, vegans or not, be it due to ignorance, incompetence or negligence.

Indeed, my understanding of the scientific consensus is that a healthy vegan or vegetarian diet is perfectly possible. However the question is what happens when such a diet is forced on a large fraction of some population, either because meat becomes too expensive, or because plant-based alterantives become much cheaper. Are most people who can scarecely afford good nutritious food right now going to be able to maintain a healthy diet when they have even fewer alternatives than currently?

Edit: just to clarify in case I'm misunderstood, I'm talking about poor people because I don't worry that I won't be able to afford to eat as much meat as I like (which isn't that much anyway- I'm Greek, so Mediterrannean diet and all that. Like, ~60% of our cuisine is vegan or vegetarian only we call it "food").

There absolutely isn't a scientific consensus. If anything, several cases have come up recently to counter the wild acceptance that anyone can live vegan just fine, and further investigation is still necessary. Just recently, the carnivore diet has taken off for multiple people, and even just significantly reducing plant-based foods in favor of animal-based foods is showing to help many people. There's also the theory of anti-nutrients and the importance of genetics which we still don't understand.

If there is one field that's an absolute mess, its nutritional sciences. The only thing one can trust is their own experience with any particular diet, their overall well-being and regular health check-ups. What works for one person can be absolutely disastrous for another.

Our livestock is given chemically manufactured b12 supplements because the soil is being depleted of the microbiology that produces and leaves it on plant material which is the natural way to get it. So everyone, including meat eaters are consumers of b12 supplements, unless they live in regions where modern agriculture does not have a strong foothold.

Similarly, modern western foods is full of supplements via “fortification” so to say that vegan diet is unnatural because of the need for supplements is a mute argument, so long as those supplements are part of everyone’s diet, and meat is just a carrier.

My point is still that the debate over plant based diets are too simplistic and based on anecdotes (on both sides). If we spent all the tax money we now spend on meat and dairy subsidies instead on unbiased research and education on general nutrition, I am convinced a lot of people would be surprised at the outcome.

The only supplements in our household are b12 and vitamin D. B12 is a supplement in everyone’s diet in the western world already, as I have argued, and vitamin D is universally recommended supplement in the northern region anyway due to lack of sun exposure in winter. Instead of getting it through fortified milk or fish oil, we take a pill, and we feel a lot better about it.

Please note I didn't comment that "anyone can live vegan just fine".

Well to address the point you are making about poor people. Looking at the current poor population of North America, the cheap meat based diet is nothing short of a disaster to general public health ridden with all sorts of dietary caused diseases such as obesity, diabetes, coronary diseases and so on. Surely, a shift towards plant based diets for this demographic couldn’t make things any worse than it already is.

My understanding about the problem with the diet of "the current poor population of North America" is not so much that they don't eat enough plant food, but that they eat all kinds of over-processed food, full of saturated fats, sugars and salt, and that any kind of food they get, meat or plant-based is of poor quality. Removing meat from that diet, even the poor quality meats they can afford right now, sounds like it would hurt their diet even more, not improve it.

I don’t think there is any evidence to support that claim.

Yeah I was raised (American) vegetarian from birth, and my parents did not consider the nutrition I needed when they cooked and I had anemia, underweight, etc. I was healthier after starting to eat meat at age 14

It shouldn't have been, because many plant-based dishes do not include the same amount of nutrients if they are cooked as opposed to consuming the raw vegetable ingredients, and people are either unaware of this entirely or completely neglect taking it into account in regards to actual nutritional value. That's before we even address nutrient bio-availability of ingredients pre-and-post preparation. You will always see tons of people crow about how many vitamins and other nutrients certain foods have, but they rarely if ever mention that with many of them you'd have to eat a dump truck full of it to even approach your daily recommended value because your body simply refuses to process much of it and passes it on as waste.
