It's Time to Take Action on a Major Health Issue: Type 2 Diabetes


We recently presented data at the Vitamin D Workshop (annual international conference) showing significantly fewer new cases of diabetes in a group with higher levels of vitamin D than in a group with lower levels.


Additional new research has shown that vitamin D can slow, or halt, the progression from pre-diabetes to diabetes.


We are looking to begin a new stage in our D*action group to focus on Community Stakeholder Projects 

Vitamin D Reduces 
Type 2 Diabetes Incidence


Your data shows a 60% reduction in type 2 diabetes:  


Our latest demonstration of your data was at the international Vitamin D Workshop in Chicago last month. As you can see in the chart below, there were 60% fewer cases of diabetes in the GrassrootsHealth group with an average vitamin D level in the 40-60 ng/ml range (as recommended by our scientists' panel) than in the general population with an average vitamin D level of 22 ng/ml.  

Major Findings

  • Median 25(OH)D in our GrassrootsHealth group was 41 ng/ml, vs 22 ng/ml in NHANES (the comparison group, the National Health and Examination Survey).
  • There were 10 cases in GRH (out of 4933 participants), 38 in NHANES (out of 4078 participants)  
  • The body mass index of the GRH group is less than the NHANES cohort
  • The average age of the GRH population is 53, that of NHANES is 47 
The full poster, as presented at the conference, is available for download here.


Data from India shows a 58% reduction in progression
from pre-diabetes to diabetes:


At the recent Endocrine Society Meeting (following the Vitamin D Workshop), a paper presented by Dr. Deep Dutta from India showed a full 58% reduction in the progression from pre-diabetes to diabetes in a group treated with daily calcium supplements and 60,000 International Units (IU) once weekly for eight weeks and then monthly compared to a group given only calcium supplements.  


Why is this important?


According to the CDC's
National Diabetes Statistics Report, 2014:  

  • 9.3% of the US population has diabetes (29.1 million people)
    • Distribution by age
      • 26% 65 and older
      • 16% ages 45-64
      • 4% ages 20-44
  • $245 BILLION is the annual cost for direct medical costs as well as indirect costs of work loss and disability
Potential savings with a 60% reduction: $147 BILLION/YEAR, and 960,000 new cases each year could be prevented.


At GrassrootsHealth, we believe

the time for action is NOW!   


The data regarding the impact of vitamin D on diabetes is abundant and it is time to start 'Moving Research into Practice.' We are starting a new Diabetes Prevention Project that will join our current D*action 'Everyone' Project; Breast Cancer Prevention Project; and Protect our Children NOW! (pregnant women) project. Given the current 'early adopters' stage of the vitamin D movement, this is still a 'crowd funded' stage, i.e., the individuals/stakeholders directly involved are the ones that fund the research projects.   


At this very moment, anyone who wants to participate in the Diabetes Prevention Project can immediately enroll in the D*action project and just indicate on the health conditions that you do have diabetes.  We will be adding some new questions for this group in the near future. 


We appreciate any help you can provide in recruiting new participants to our group to see if we can not only prevent diabetes but actually impact the course of the disease.    

Introducing D*action Community 
Health Action Bridge Projects


It is time to expand the current D*action Stakeholders from an individual movement to creating community projects - projects focused on community-wide participation with results that we can take to local public health officials for local action!


We are aiming at significant public health action in local communities by enrolling a number of people in local projects and then taking the results directly to the public health officials for action.  The projects can be any of our existing ones or, if you can identify a specific community health condition, please let us know and we'll work with you to further define it.    


Ready to make a bigger difference? 


Look at the following ideas to see which one(s) make sense to you, or let us know if you have your own suggestion!  We'll help you get started right now.



  1. Purchase one or more tests to give to family and friends for their participation. 
  2. Hold a meeting of friends in your home to solicit their participation in your group or community project. Participation could be through their individual enrollment and/or donations. A list of suggested information pieces for your meeting can be found here
  3. Share information with business professionals who might be in a position to participate as a community sponsor. These people would be listed as sponsors for your community.

We, with you as community leaders, can truly move this research into practice NOW!


We are moving into a new stage - that of urgent implementation of the findings of your data, of creating community action groups and increasing the fundraising reach. My very personal thanks for your involvement in this new method of moving research into practice. It truly is a 'mass movement' in health.
