Criteria to associate a health problem with low vitamin D


If a health problem has more than 7 of the following factors
then I believe that vitamin D deficiency might be a cause

  1. Big worldwide problem which has increased in the past 40 years Incidence of 30 health problems has, on average, doubled in a decade
  2. Problem occurs around the world
  3. Occurs more often when Far from Equator - but this factor has been decreasing during the past 20-30 years
    people can stay indoors, thanks to air conditioning
  4. Season - problem is worse in Spring when the vitamin D in the blood is the lowest
    Can now also happen in the Summer in the tropics if you can afford the air conditioning to stay away from the hot sun.
  5. Overweight - fat ties up a lot of vitamin D and the obese often do not feel comfortable out of doors
  6. Smoking - ties up vitamin D
  7. Medical problems which reduce vitamin D - MS, kidney, gut, liver, kidney...
  8. Dark skin - who get about 1/4 the amount of vitamin D per minute in the sun as those with light skin
  9. Seniors - who also get about 1/4 of the vitamin D per minute as those with dark skins - for a different reason
  10. Atmospheric haze - which reduces the UVB getting to the people - typically in cities
  11. Problem gets worse when taking a drug which reduces vitamin D
  12. A Patent has been issued for Vitamin D to treat or prevent the health problem
    such as: Breast and many other cancers, Obesity, Bone loss, Prostate, Fall prevention, stroke and other Cardiovascular, Immune system, heal wounds and reduce scars, Kidney disease, Diabetes, improve fertility, decrease pregnancy problems, (SAD), multiple sclerosis, chemoprevention of cancer, accelerate fracture healing, metabolic syndrome, periodontitis, gingivitis, endometreosis, hair loss, asthma, allergy, etc.
  13. Strongly associated with a vitamin D related disease
  14. Worse around the age of weaning from formula which was fortified with vitamin D
  15. Is more common in rich families – who are more likely to apply sun screen and stay indoors
  16. Reduced by Ultraviolet light - from sun or UVB bulbs
  17. More in urban areas – less UVB in urban environments
  18. Less at high altitude - where there is more UVB
  19. Less if person works outdoors 8X more likely to die if work indoors (1915)
  20. Worse in areas with increased clouds and rain - keeping people indoors, also, there is less UVB when outdoors
  21. Worse if born less than 12 months after previous sibling or as a twin - both of which reduces vitamin D levels
