The Big Vitamin D Mistake! A new study

by Paleo Rob on 07/12/2017

Huge new study from Finland. Abstract is below, but its something we have been saying for years. The emphasis is mine.

Since 2006, type 1 diabetes in Finland has plateaued and then decreased after the authorities’ decision to fortify dietary milk products with cholecalciferol. The role of vitamin D in innate and adaptive immunity is critical. A statistical error in the estimation of the recommended dietary allowance (RDA) for vitamin D was recently discovered; in a correct analysis of the data used by the Institute of Medicine, it was found that 8895 IU/d was needed for 97.5% of individuals to achieve values ≥50 nmol/L. Another study confirmed that 6201 IU/d was needed to achieve 75 nmol/L and 9122 IU/d was needed to reach 100 nmol/L. The largest meta-analysis ever conducted of studies published between 1966 and 2013 showed that 25-hydroxyvitamin D levels <75 nmol/L may be too low for safety and associated with higher all-cause mortality, demolishing the previously presumed U-shape curve of mortality associated with vitamin D levels. Since all-disease mortality is reduced to 1.0 with serum vitamin D levels ≥100 nmol/L, we call public health authorities to consider designating as the RDA at least three-fourths of the levels proposed by the Endocrine Society Expert Committee as safe upper tolerable daily intake doses. This could lead to a recommendation of 1000 IU for children <1 year on enriched formula and 1500 IU for breastfed children older than 6 months, 3000 IU for children >1 year of age, and around 8000 IU for young adults and thereafter. Actions are urgently needed to protect the global population from vitamin D deficiency.

And it really is not that difficult to do. I have been taking 5000 IU softgels from Life Extension which I get in packs of 360 (enough for a year) and it costs less than $15.

As an aside however, remember you need to also increase your consumption of Vitamin K2. Vitamin D helps absorbe dietary calcium but Vitamin K2 send its to your bones. Big leafy greans, hard cheeses, grass fed butter all have Vitamin K. Or if you find that difficult, take a supplement every now and then.

Interesting new umbrella review (review of meta-analyses on coffee) in the Annual Review of Nutrition titled “Coffee, Caffeine, and Health Outcomes: An Umbrella Review“. They authors went through 91 meta-analyses of observational studies on coffee consumption.

In the review that found that coffee was associated with a probable:

  • Decreased risk in breast cancer,
  • Decreased risk in colorectal and colon cancer,
  • Decreased risk in endometrial cancer,

Vegetables – Just add fat!

June 29, 2012

I like vegetables. I don’t hold them to the great esteem that most others hold them to, but I like them. To me they add a mix of flavour, texture and colour to a meal, and of course, they have some pretty decent nutritional properties. Your vegetables are a good source of vitamins and minerals, […]
