Food Politics

I agree that our vitamin D sources should be as natural as possible. However, I am not yet comfortable with the recommendation I often hear to apply sunscreen after 15 minutes in the sun. Since I was a child, I heard that in order for sunscreen to be fully effective, it should be applied 1/2 hour before going out in the sun (The skin cancer foundation also states this the protocol for applying sunscreen: http://www.skincancer.org/the-scfs-guide-to-sunscreens.html). Given this advice goes back at least 20 years, I wonder if that has ever been challenged or debunked. Are there any studies that show a significant protective effect with it being applied after going out in the sun? The efficacy vs. effectiveness debate comes to mind.

One of the leading researchers into the mechanisms of vitamin D, Michael Hollick MD PhD, was asked to leave the Dermatology department at Boston University (he was co-appointed to Dermatology and Internal Medicine) after making the same exact suggestion that you made, i.e. to spend 15 minutes per day in full sun. A controversial topic, to say the least.

But, even since you published your article, yet another link seems to have been solidified, this time between vitamin D and MS. I hope that the Institute of Medicine panel will have some good recommendations; in the meantime myself and many other physicians are taking 400 IU supplements, with a goal of 600-800 IU total per day.

yeah its quite good render more information about it.

A Canadian company, Naturally Nova Scotia, makes supplements from foods instead of synthetics. The have vitamin C from fruit, herbal tinctures, green drinks, vitamin D3, and others.

Vitamin D is not a vitamin. It was incorrectly identified as a vitamin when it was discovered. The active metabolite, 1,25 dihydroxy vitamin D, activates the Vitamin D Receptor (VDR) in our cells which is key to the functioning of the immune system. All the “vitamin” D we need is produced and controlled by the body. To add it to foods beyond any natural level is to upset what the body is trying to do naturally.

Go to Bacteriality.com for more complete information. The vitamin D lobby is doing the public a great disservice in pushing vitamin D into our food supply.

Doctors who prescribe huge levels of D do so blindly. They measure the level of 25 hydroxy vitamin D, the inactive metabolite, in the blood and conclude it is low. If they would take the time to measure the level of the active metabolite, 1,25 dihydroxy vitamin D, they would see the level is actually high (in most people) thanks to our friends in the food supplement business.

I believe that many of today’s alarmingly high levels of autoimmune diseases are directly linked to the food industry’s belief that vitamin D is a good thing to add to food. We can’t escape it, and it is doing us grave damage!

1,25 dihydroxy vitamin D,

Is there a simple test for the above substance?
