Sun avoidance can lead to Vitamin D deficiency

Interestingly Vitamin D deficiency is on the RAPID rise.

Vitamin D is a needed for a massive range of actions in the body including: bone formation, blood clotting, heart and muscle action, immune factors and is a co-factor (small but integral component of many other process).

Your body needs more if you drink in excess, have breast cancer, have Crohn's disease, are pregnant, a vegetarian and have any bone issues.

You can find it in fish oils (Good old Cod Liver Oil is very high in Vit D), egg yolk, milk, sprouted seeds, and the sun helps your body make it on your SKIN! but you need approx 20 minutes of sun a day on a limb (such as an arm).

Think of all the elderly people shoved away in nursing homes currently being deprived of sunlight. No wonder they trip, fall and break bones. Yet again a small little health issue, that would save you and I (ie the government) millions in health care $$$ and would help a lot of people AVOID pain and immobility due to bone fractures.

Ok, off my high horse....

The recommended daily amount is 400 IU. If you are treating a deficiency you will need 400-1600 IU per day. 40 IU = 1 Microgram of Vitamin D.

high dose calcium can decrease production of Vit D and this can result in sarcoidosis, diabetes and cancers.

I knew some of this, but obtained most of my research from my biochem mentor, Henry Osiecki and his excellent book: The Nutrient Bible, www.bioconcepts.com.au
