Widespread Vitamin D Deficiencies
A lot more attention is being put on Vitamin D these days, particularly by doctors. This is because deficiencies of it are very common and it is a much more important nutrient than has previously been given credit for.
Vitamin D is produced by the body in response to skin exposure to the sun. It is also found in reasonable quantities in some fish, fish liver oils, and eggs. It is also frequently added to grains, cereals and dairy products in insignificant quantities.
Doctors mainly recommend Vitamin D to help with healthy bones and prevention of osteoporosis, however there are deficiency links to cognitive impairment in adults, severe asthma in children, high blood pressure, Multiple Sclerosis, achy bones, ADHD, Cancer, Diabetes, and more.
It’s generally accepted that people prone to Vitamin D deficiency are those who have digestive problems, such as Crohn’s, obesity, kidney disease, dark skin, poor exposure to sunlight, and poor diet.
It’s estimated that 90% of senior citizens and 70% of children between 6 and 11 are vitamin D deficient. Statistics for the rest of the population also shows significant deficiencies.
Vitamin D has been shown to fight infections, helps reduce blood pressure, atherosclerosis, heart attack and stroke. One study showed that vitamin D deficiency increased the chance of a heart attack by 50%.
Vitamin D is important for DNA repair and metabolism, and has been shown to be important in conditions like Multiple Sclerosis.
One study showed three quarters of people with Cancer were Vitamin D deficient. Research in the laboratory suggests that vitamin D has anti-tumour properties, regulating genes involved in the multiplication and spread of cancer cells.
A study in Japan showed children who took high doses of Vitamin D per day had a 40% less chance of getting influenza – the same as the flu vaccine.
Dr Michael F Holick, PhD, MD, a leading vitamin D proponent, is an Endocrinologist at Boston Medical Center and professor at Boston University School of Medicine. In an interview he summed it up quite succinctly, “There is an avalanche of studies reporting the association with vitamin D deficiency and increased risk for chronic illnesses including heart disease, type 2 diabetes, multiple sclerosis and neurocognitive dysfunction.
