Do Vitamin D Supplements Help with Diabetes, Weight Loss, & Blood Pressure?
Most studies on vitamin D may not be all that useful, the body likely did not evolve to use vitamin D to help prevent diseases that we’re interested in. The whole point of using vitamin D to regulate all sorts of processes in the body has likely little to do with preventing cancer or heart disease, as cancer and heart disease were not a major driving force in our evolution. We have to consider first what is most likely the role of vitamin D and then consider what the most likely health benefits could be and then consider how to best test such ideas. It seems to me that the whole point of making gene expression depending on the amount of Sun exposure, has likely to do with fine tuning the body to the available food resources.
An animal whose calcidiol levels are dropping may have to survive a harsh winter a few months later. But at the time the calcidiol levels are dropping it may still be autumn the temperature may be high and there may still be plenty of food around. But the calcidiol levels tell the animal that harsh conditions are ahead, so it may be a good idea to save energy, invest a little less in maintaining optimal physical fitness and divert energy to build up some fat reserves. In the tropics where there s no winter, there may be prolonged drought periods; many animals burrow underground and then their calcidiol levels will also go down.
So, this suggests that high vitamin D levels will make it easier to maintain optimal physical fitness. There are some research results that are consistent with this idea, e.g.:
“Our findings suggest that vitamin D levels are Continue reading
