    I’ve always found it intuitively wrong to believe that there is a one-size-fits-all ‘level’ of vitamin D for all ethnic groups or the need for supplementation of any sort. My ancestors, Northern Europeans, lived to a ripe old age without worrying about levels. All of our ancestors protected their skin from the sun and insects with clothing. There were no shorts or tank tops, they would have been thrown in jail for indecency.

    Which brings me to my point. My father in law, who is now 93, has spent minimal time outside for the past 12 years. He eats meat, bread and fruit, does not eat dairy and few vegetables. His vitamin D level is normal. That’s right, normal. Why? How is that possible, if all the research is correct?
