Vitamin D and Cancer Prevention: Shining Light on the Current Research

Friday, December 02, 2011
12:00 – 1:30 pm EST




  • Discuss dietary guidelines for vitamin D in terms of recommended dietary allowances, tolerable upper intake levels, corresponding serum 25(OH)D levels, and evidence to support the new guidelines
  • Identify strengths and weaknesses of data relating to vitamin D and cancer prevention
  • Discuss biological basis by which vitamin D inadequacy or excess influences cancer risk 
Like most nutrients, recommendations for public health, let alone one specific disease, is complex, especially remembering that cancer is not cancer is not cancer, as there are 200+ different types of cancer diagnoses with different cancer biological processes involved.

I needed to miss hearing some of the talks about vitamin D at the conference I attended last week, but I heard enough to know there are concerns about a "U-shaped" curve, which in essence means that more/bigger is not always better and may even be potentially harmful. I am making a strong bet that research discussing this concept will be discussed during this webinar.

In addition, the previous webinar about the potential for curcumin (a component of the spice turmeric that has anti-cancer activity) to impact the cancer process has been archived for viewing and the link to that webinar is also available on-line at with continuing education credits available for Registered Dietitians.

I have not had time to view the curcumin webinar yet, but I know there is enough research already showing potential benefit that I considered opening up new fields on our farm to plant turmeric (until I read about the growing conditions needed and realized I would need to live in the tropics, like southern India, like where it is grown commercially!). 

Happy viewing and learning!

PS - We're still planting garlic, even with our wet fields this fall and light snow today! It's been a slower than expected planting season. I was composing haikus in my head this afternoon while working in the field to keep my focus off my cold fingers. Here is one I can remember:

Will this be available for later viewing - I won't be home at that time. Thanks Diana

There is an excellent discussion about U-shaped curves from one of the world's experts in Vitamin D, Professor Reinhold Vieth
