  Which ones are exclusive?

    I’m not a nutritionist, but I know for a fact vitamin a, among others, is not made by plants. I think people should probably just talk to their health care professionals. strangers on the Internet need have no credentials, and often have motivated reasoning.

      Humans synthesize Vitamin A from Beta Carotene in plants. Only a small minority of people who are genetically predisposed to less efficient conversion of Beta Carotene would need to supplement with the retinyl form (readily available in supplements)

      Per the NIH:

      The human diet contains two sources for vitamin A: preformed vitamin A (retinol and retinyl esters) and provitamin A carotenoids [1,5]. Preformed vitamin A is found in foods from animal sources, including dairy products, eggs, fish, and organ meats [1,2]. Provitamin A carotenoids are plant pigments that include beta-carotene, alpha-carotene, and beta-cryptoxanthin [1]. The body converts provitamin A carotenoids into vitamin A in the intestine via the beta-carotene monooxygenase type 1 BCMO1 enzyme [1,3,6], although conversion rates may have genetic variability

      You can get vitamin A from carrots. That’s one of the reasons the British beat the Germans.

        most people can synthesize vitamin a from precursors found in carrots. talk to your doctor

  that’s not true

  Are you sure about that? Got any examples of nutrients that make humans obligate carnivores?

    I didn’t say that. you’ve constructed a straw man.

      reductio ad absurdum, actually.

      You claimed that this statement was not true:

      There are no nutrients that are exclusively available via meat/dairy.

      i.e. claimed that there are some nutrients that can only be sourced via meat or dairy.

      An obligate carnivore must eat meat to live, like, say, if the only source of needed nutrients is meat?

      Where did I lose you on this? Is it the “or dairy” escape hatch?

      FFS, you could have just given an example of a nutrient you mistakenly think is only available via meat or dairy. Then I could have judged your post on its merits instead of this displeasure of a thread.

  Did you continue reading what was after that quote? That part that says no nutrients except for B12? You quoted it out of context.
