what is rabbit starvation?

"...This ceiling, Cordain thinks, could be imposed by the way we process protein for energy. The simplest, fastest way to make energy is to convert carbohydrates into glucose, our body’s primary fuel. But if the body is out of carbs, it can burn fat, or if necessary, break down protein. The name given to the convoluted business of making glucose from protein is gluconeogenesis. It takes place in the liver, uses a dizzying slew of enzymes, and creates nitrogen waste that has to be converted into urea and disposed of through the kidneys. On a truly traditional diet, says Draper, recalling his studies in the 1970s, Arctic people had plenty of protein but little carbohydrate, so they often relied on gluconeogenesis. Not only did they have bigger livers to handle the additional work but their urine volumes were also typically larger to get rid of the extra urea. Nonetheless, there appears to be a limit on how much protein the human liver can safely cope with: Too much overwhelms the liver’s waste-disposal system, leading to protein poisoning—nausea, diarrhea, wasting, and death" Discovery magazine-

how much vitamin C does one need before scurvy sets in?

"...In fact, all it takes to ward off scurvy is a daily dose of 10 milligrams, says Karen Fediuk, a consulting dietitian and former graduate student of Harriet Kuhnlein’s who did her master’s thesis on vitamin C. (That’s far less than the U.S. recommended daily allowance of 75 to 90 milligrams—75 for women, 90 for men.) Native foods easily supply those 10 milligrams of scurvy prevention, especially when organ meats—preferably raw—are on the menu. For a study published with Kuhnlein in 2002, Fediuk compared the vitamin C content of 100-gram (3.55-ounce) samples of foods eaten by Inuit women living in the Canadian Arctic: Raw caribou liver supplied almost 24 milligrams, seal brain close to 15 milligrams, and raw kelp more than 28 milligrams. Still higher levels were found in whale skin and muktuk." -Discovery
