No, Vitamin C Does Not Replace Exercise

(Peter Lipson, Forbes) The LA Times is reporting that vitamin C may have the same benefits as exercise. The Times headline was a bit circumspect, but some outlets have been a bit more enthusiastic… I’m sure this study was of some interest, but not enough to justify newspaper headlines…
[I]t is just a tiny study, with no clinical significance of any kind. To be clinically significant, it would have to be a much larger study, it would need a control group of subjects who did not get exercise or vitamin C, and it would have to measure a clinically relevant outcome, something like blood pressure, heart attacks, strokes—something that would tell us if the findings can help real patients.
The only way to decrease the risks of being sedentary and obese is to eat healthier and to get moving.
