From: Rob on 16 Jan 2006 19:01 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? Rob
From: montygram on 16 Jan 2006 20:11 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.]" Source: http://www.healthythyroid.com/vegetableoils.htm

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. > 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.

The diet of the aboriginal Ihalmuit of the Barren Lands of Canada has been studied, although I'm referring to memory of study many years ago - it was almost entirely caribou meat. They required one handful of fat for each three of meat to avoid protein toxicity, they lived in a very cold climate so burned off all that fat to maintain body heat, and they drank copious amounts of tea to deal with the protein digestion byproducts. The common name of the widespread northern plant Ledum groenlandicum is Labrador Tea, and it's leaves contain a lot of Vitamin C. So do pine needles and the leaves of many other northern plants that can be used as teas.
From: John Sankey on 17 Jan 2006 10:30 I should have added that the northern Cree and Inuit collect berries during the summer, then keep them for the rest of the year. Mostly naturally frozen, but occasionally they ferment a bit. 10g typical northern berries gives 1mg C. If Stefansson ate a truly northern diet, he would have included some.
