Recently two Swiss researchers published a review of all the studies on the vitamin D content of various protein food groups.

I agree 100% with your point: “The time has come to fortify more foods with vitamin D. Many people need to get vitamin D in their diet or they will not get it. Eggs, cereals, breads, canned vegetables, fast foods, yogurt and cheese could all be fortified. Yogurt and cheese are made from unfortified milk and thus have little or no vitamin D.”
I am embarrassed to say that a year ago I didn’t really understand the necessity and importance of food fortification.
However, after outreaching at health fairs in some of the poorest communities in New Haven, I have a very (very) different perspective.
Certainly folks need to be educated on the benefits of appropriate sun exposure and adequate vitamin D supplementation; however, life often gets in the way for everyone, but particularly the poor…. The importance of sunlamps and supplements can be lost in the activity of daily survival. You are very correct: For many it needs to be D via food…or they will not get it at all.
Perhaps this will be my 3rd video 😉
(BTW–Bessie the Cow is looking very upfront, direct, and in our faces here)
Is the attached petition still valid? I know that in 2011 VDC desired to get 10,000 signatures on this petition before proceeding forward. And I see that 2,500 signatures were received in 2011.
I’m in a great spot to get the remaining 7,500 signatures. Why not let me me? I think you understand very well that I walk my talk, Dr. John Cannell. 🙂
But, it would be foolish for me to “hoof it” if there is some sort of time limit, etc. After all, two years have passed.
I would appreciate it if you would let me know via this blog, email or Brant.
I hope you are well !
Or, Brant~~It’s fine if you call me. I have several things to discuss with you anyway.
Brant, a 2013 AJCN study concludes that the natural vitamin D in animal foods [25(OH)D3] is about 5 times more potent than ordinary D3 (cholecalficerol) at raising winter-time blood levels based on a 10-week RCT with 56 adults age 56 and over.
The authors conclude that the ability of foods naturally rich in 25(OH)D3 to improve vitamin D status may be significantly underestimated. See Am J Clin Nutr 2012;95:1350-56. I’m puzzled why the Swiss study above fails to mention or factor in this important finding. Can you please explain?
While 25OHD is very potent, they’ve still failed to find 25OHD in abundance in meat products. I think there is some thinking that meat has more than we think, or that we just haven’t looked for it enough in meats, but at present, they just haven’t looked that much and when they do, they don’t find much there.
Why isn’t this pertinent any more?
Are you supportive of food fortification?
From my outreach I can tell you that there are many poor people, single moms, elderly, and those suffering from illness(s)…who are so laden down with the problems of day-to-day survival they just cannot focus on supplementation.
This folks won’t ever get adequate vitamin D if not for food fortification.
How many others here in this virtual community are supportive of food fortification?
I can GET those 7,500 signatures for the above-linked petition.
David: Will you help me?
(I apologize Brant for glomming space to stand on my soap box…and this isn’t something I expect you to answer–and, most importantly: I hope you can forgive me for returning to this subject)
Wouldn’t food fortification solve at least some of the problem?
Doesn’t the blog read:
“The time has come to fortify more foods with vitamin D. Many people need to get vitamin D in their diet or they will not get it. Eggs, cereals, breads, canned vegetables, fast foods, yogurt and cheese could all be fortified. Yogurt and cheese are made from unfortified milk and thus have little or no vitamin D.”
I agree with the above statement. It makes sage sense.
Why is the petition no longer valid?
“The beneficial effects of vitamin D supplementation for several health-related issues, including the prevention of diabetes, are a topic of intense discussion.
Data from epidemiological studies suggest a correlation between vitamin D deficiency and higher prevalence of both type 1 and type 2 diabetes (T1D and T2D).
In animal models, vitamin D deficiency predisposes to diabetes whereas vitamin D supplementation prevents disease.
Nevertheless, well-designed clinical intervention studies are lacking. We discuss here the evidence for a role of vitamin D in diabetes and propose that vitamin D deficiency should be avoided, especially in all at-risk people.
This should be possible by implementing global guidelines and by focusing on daily dietary supplementation with small doses of vitamin D.”

A recently published meta-analysis proves that vitamin D supplementation is a safe and effective treatment for atopic dermatitis.
