Do you know anyone who has been diagnosed with a medical condition caused by D deficiency?
I think it's a little more complicated than that. People with low vit D can get more colds and flus. My bone density stabilized once I began taking regular vitamin D. People develop dementia over a long period of time and cancer comes on that way too sometimes. Poor vitamin D status in the elderly is associated with chronic pain. Vitamin D works by lowering insulin resistance, which is one of the major factors in heart disease. It is also used by the thyroid gland, which secretes a hormone that regulates the body's levels of calcium, which in turns helps regulate blood pressure. There are MANY medical conditions that low vitamin D can play a role in.
Cause is an interesting word. http://www.sciencebasedmedicine.org/ind ... l-disease/
Wouldn't it be nice if life were simple--and we wouldn't need to wait for a rooster to lead us to the hen that laid all those eggs in our basket? I don't know. Maybe life without chickens would be boring. http://www.mayoclinic.com/health/vitami ... N=evidence
Vitamin D deficiency
Vitamin D deficiency is associated with various diseases, such as bone loss, osteoarthritis, cognitive issues, kidney disease, respiratory concerns, diabetes, gastrointestinal issues, cardiovascular disease, etc. Vitamin D supplementation can help prevent or treat vitamin D deficiency.
I don't think Dr. McDougall has said that deficiency or insufficiency of vitamin D doesn't or hasn't or won't or can't contribute to or cause health problems. His position on the issue appears to be that he questions the higher levels that some consider insufficient. As I understand it, his conclusion is that normal/sufficient is (should be considered) 20 or greater. He recommends sun exposure as the best way to get D. His second option is tanning booths and sun beds, which I personally have an aversion to and would choose last and probably then only under duress.
He does not recommend vitamin D supplements for most people. Note that he wrote most people
. (This was in the March 2011 newsletter article.) He didn't write that he never recommends or would never recommend a vitamin D supplement for anyone ever.
I don't know anyone who's been to the moon on a rocket, but I do know someone who says she can astral travel. I also know there are probably millions of people--and I know several--who will tell you they're going to or hoping to go to a place called Heaven when they die even though there's really no proof it exists. So what? I wonder if there are chickens there....I wouldn't want to be bored.
Have a great day, everyone! Or just do the best you can.http://www.youtube.com/watch?v=o59S7C1nYfc
