B12 is the one I know a number of vegetarians have trouble getting from plant based sources. I've had trouble with it ages ago, and a friend of mine has been told by his doctor that he has to eat meat because of this.

The solution is really simple, though: eat less meat. We don't need meat every day. Once or twice a week is more than enough, and if everybody did that, it would greatly reduce this problem.

A doctor suggested eating meat to resolve a B12 deficiency? I find that strange. Low B12 is common among meat-eaters and vegetarians alike. It's a bacteria-byproduct and easily supplementable.

This is the first time I've heard that. I know a number of vegetarians who specifically had b12 deficiency, and every single time, the answer was that we could only get b12 from animal products. One of them gets b12 supplements aware that it's the only animal product she consumes.

I checked Wikipedia though, and it agrees with you, which makes me wonder even more why I've heard this exact same experience from several unconnected vegetarians.

Fermented foods like Idli can get you enough Vit B12. No need to eat meat.

Your friend couldn't take a B12 supplement?

Apparently not. I don't know his medical details, though.

Although I do wonder, if we're wrong about B12 only coming from animals, is it possible that we, or possible even Dutch physicians, are under-informed about our options?
