Vitamin C is the one vitamin that is relatively scarce in animal products. But it appears to be the case, as it certainly is for the B vitamins, that the more fattening carbohydrates we consume, the more of these vitamins we need....
Vitamin C uses the same mechanism to get into cells (where it’s needed) that glucose does, so the higher our blood sugar level, the more glucose enters the cells and the less vitamin C. Insulin also inhibits what’s called the uptake of vitamin C by the kidney, which means that when we eat carbohydrates we excrete vitamin C with our urine rather than retaining it, as we should, and using it. Without carbohydrates in the diet, there’s every indication that we would get all the vitamin C we ever needed from animal products. This makes sense from an evolutionary perspective as well, since any human populations that lived far enough from the equator to see lengthy winters would have gone months, if not years, at a time—during ice ages, for instance—without eating anything but what they could hunt. The idea that they required orange juice or fresh vegetables to get their requisite vitamin C every day seems absurd. This would also explain why isolated hunter-gatherer populations that ate virtually no carbohydrates and certainly no green vegetables or fruits still thrived.
Taubes, Gary. Why We Get Fat: And What to Do About It
Zero carb lowers the body's need for Vitamin C. Here are some quotes from Gary Taubes' Why We Get Fat and What to Do About It:I would add the caveat that one shouldn't rely on pemmican or salted or processed meats for vitamin C. Multiple ZCers at the ZC forum (Zeroing in on Health) and elsewhere developed scurvy symptoms when they relied heavily on pemmican. Not all did, and those who did tended to also have a history of GI issues and other problems, but even those who didn't might theoretically be deficient in vitamin C without knowing it. As I recall, at least two of the ZCers resolved the problem by cutting back on pemmican and eating more fresh cooked meat. Another added plant foods that contain vitamin C, such as potatoes and OJ.
