404 Vitamin D News [23 Jan 2017]
The days are slowly getting longer but we are still months away from even beginning to get any vitamin D from sunlight which will start mid-April. This week I will share several news items about this critical vitamin.
A large multi-ethnic cohort study published in Molecular Psychiatry found that maternal vitamin D deficiency (less than 25 nmol/L) during pregnancy was associated with a 3.8 times higher rate of autism-related traits in the children at 6 years of age. Other studies have shown vitamin D deficiency to nearly double the risk of premature birth.
An animal study published in Frontiers in Physiology suggests that vitamin D could play a role in preventing Metabolic Syndrome by modulating gut microbiota. Previous studies have shown an association between D deficiency and obesity, insulin resistance and non-alcoholic fatty liver disease (NAFLD), all part of Metabolic Syndrome. Mice fed a high fat, low D diet developed unhealthy gut flora, glucose intolerance, insulin resistance, NAFLD, and elevated levels of inflammatory markers compared to the high fat, adequate D diet group.
In a randomized clinical trial, relapse rates for Crohn’s Disease patients were 33% for those receiving 10,000 IU vitamin D and 69% for those taking 1,000 IU. This strongly suggests that Crohn’s sufferers do better with higher D levels.
In a randomized controlled trial published in the journal Medicine, 120 adults with fatigue and vitamin deficiency (less than 50 nmol/L) received either a single dose of 100,000 IU vitamin D or placebo. The vitamin D group reported more significant improvement of fatigue than the placebo group.
Finally, William Grant of the Vitamin D Council calculated the benefits of raising the vitamin D levels of all Canadians to at least 100nmol/L. Levels currently vary with age and season but average 61 nmol/L with 92% (summer) and 96% (winter) below the target level. Based on published studies, Grant estimated reductions in incidences of cancer, cardiovascular disease, dementia, diabetes, MS, respiratory infections and musculoskeletal disorders. He then calculated a reduction in annual premature deaths of 23,000 and a saving of $12 billion per year. New evidence of stronger effects of D on the risk of Alzheimer’s and clinical depression would push these numbers even higher. What are we waiting for??
