> [D and] B12. Folks, get both of these checked.

Yes, please. I'm spreading this news for years. Many are deficient in both. B12 has a name for being low in veg*ans, while that is true many omnis are deficient as well.

It's good to have more papers published on "high-dose D3". But by what I read this has been know for many years.

And shun multi-AZ tablets, they provide a false sense of security. Eat loads of fresh produce and beans, that should help with most of your nutrition needs. Shun dairy and processed foods -- they kill you. Limit (or drop) meat, fish and eggs. Finally you want to eat a brazil nut every day for your selenium.

Supplement D3 and B12. Possibly (after doing your research) iodine, iron, high-DHA omega 3.

Drop meat, fish, eggs, dairy products...what's left? Vegan cuisine?

Not that it wasn't obvious, but you should still disclose your bias.

Good luck with your vegan diet. I hope that beans and veggies can provide for all your nutrition needs. But better keep going to those regular doctor checkups.

> Vegan cuisine?

Yes. Let's call it plant-based. As veganism is much broad and often based on ethics. Where plant-based diets mostly based on scientific findings. Especially the whole-plant (WFPB) diet seems to have a lot of scientific backing in being the healthiest diet.

> I hope that beans and veggies can provide for all your nutrition needs.

Thanks. But this is more then well proven by studies now. And I did my checkups, only D and B12 were deficient (now fixed). I never felt healthier. See "the china study" and "the adventist studies". Also the nutritionfacts.org website/YTchannel and MicTheVegan will give you a good overview of the scientific evidence behind the health benefits of a whole plant-based diet.

We're all biased. I'm not paid say this, or paid by big-broccolli, thus no conflict of interest :)

What are you smoking?

Without being too facetious, do you have anything to contribute as to why you might think dropping meat, fish, and eggs from your diet would be detrimental?

The benefits of eliminating meat include reduced markers of inflammation within the body. Reduction of cholesterol. Changes in gut microbiome which as the emerging science is describing may have a more important impact on mood and cognition than we previously thought. Lengthening of telomeres. Oh and how about making the single most impactful change an individual can make to reduce climate change.

From my understanding of the subject the only real downside from eliminating meat or reducing it substantially is the reduction in essential B vitamins provided. This is widely recognized by those who promote a plant-based diet and the solution is to simply supplement with a super B vitamin supplement.

So what are you smoking?

Thanks for chiming in.

> the only real downside from eliminating meat or reducing it substantially is the reduction in essential B vitamins provided.

Only the B12 actually. And omnis are also often deficient. Even industrially farmed animals were deficient until they started to supplement their feed (so when eating industrial meat, you indirectly eat supplement).

The B12 deficiency in those eating plant-based is a hygiene issue: before settling in villages we ate a lot of "soil" with our food, and drank a lot of soil-run-off surface water. As the soil contains a lot of B12 and the microbes that create it (which probably can even live in our intestines).
