They've been doing this to fish for a long time[1], I guess it just got approved for beef and chicken?

OP is from 2016; apparently it's been used for beef and chicken with FDA approval since it was brought into widespread use.

a bit of a tangent, but i've always wondered why "wild-caught" is such a marketing thing. to me, if it's wild-caught, chances are high that it was not done sustainably, which is opposite of how farmed variants are procured.

>if it's wild-caught, chances are high that it was not done sustainably, which is opposite of how farmed variants are procured.

AFAIK farmed variants aren't exactly sustainable either. They require enormous amount of smaller fish to feed the bigger fish they're farming, and those smaller fish are still wild caught. In addition, fish farms pollute the areas around them, in the form of disease/parasites or waste.

Headline needs a "(2016)" suffix.

And note that this has been going on for a lot longer than that.

Tangent question- any nutrients or minerals that only come from meat? (Vegetarian that eats eggs and milk here)

I've heard of a few, but from research they aren't actually necessary or can be metabolized.

I do food cost studies and the research is given away free to millions of people.

Given how many health vegetarian humans are our there, I'd say obviously not.

There are things that are harder to come by outside of meat. Iron is a big one I think, certain amino acids too I would guess.

Iron is available in plants. The question is mostly, what animals can produce by consuming plants that we need and we can't produce on our own.

No.

If they have a master's specifically in vegetarian diets what makes them qualified to talk about meat

Yes - vitamin B12 isn’t found in plants. Other minerals are also harder to come by, like Zinc and Iron. The bio-available form of Omega-3 Fatty acids, EPA, DHA, and DPA are also only in animal products. Long-term veganism without health consequences isn’t possible without careful supplementation. If you eat fish and eggs, you are mostly covered, although I recall studies showing vegetarians had lower levels of B12 and other vitamins/minerals vs their omnivorous counterparts.

You can get all vitamins/minerals needed by just eating animal products, if you so desire. Plants don’t contain anything essential for human health, so far as we can tell today.

Collagen is really low for vegetarians which, I don't know about health consequences, but doing without it for long enough makes you look sickly.

Worth noting that there are a wide variety of B12-fortified plant-based foods available (non-dairy milks, cereals, etc.). One can also find algae-based EPA + DHA supplements.

Yes, this is true, although I don’t believe these tend to be very healthy foods. Algal Omega3’s are a good source (although technically not a plant).

This is not relevant to the question asked since it's about vegetarians who gave eggs and milk.
