  1. I'm sure many here are aware of Vilhjalmur Stefansson, who had lived
    with the Inuit, and had taken part in a year-long, meat-only diet
    under close medical supervision.

    Question: If he ate a diet of only meat, how did he not get scurvy? Are
    there some sources of meat, fish, shellfish, etc, that would supply
    enough vitamin C to prevent scurvy? I have heard that the actual amount
    of vitamin C necessary to prevent scurvy is miniscule, i.e. 3-5mg. Is
    this so?

  2. Biochemist Ray Peat has discussed a similar experiment (and also
    mentioned a relevant dog study) in the following passage:

    "Fifty years ago, it was found that a large amount of cod liver oil in
    dogs' diet increased their death rate from cancer by 20 times, from the

    usual 5% to 100%. A diet rich in fish oil causes intense production of

    toxic lipid peroxides, and has been observed to reduce a man's sperm
    count to zero. [H. Sinclair, Prog. Lipid Res. 25, 667, 1989.]"

    Nobody asked about cod liver oil.
    Cod liver oil contains, as the name states FAT soluable vitamins which
    ascorbic acid is none of.
    This has nothing to do with the question at hand.

    AND Dogs are able to perform vitamin C synthesis.

    Nobody mentioned something about that either AND the study is 17 years old-
    there are newer results with different outcomes.

    ... another one of you "on point" replies?

    I guess that would put you in the Eskimo Kook group?

    As the science professor MartyB like to say a few years ago some human
    beings can in fact perform vitamin C synthesis. Perhaps, Vilhjalmur had
    this genetic variation?

    And, he could have had borderline scurvy. Most moderns on a steady
    Hamburger, French fry, and coke diet suffer from borderline scurvy.
