but it's still a negative about D.
That's really weak. Dr Cannell was knocking the idea down in that report. Here is his opening clip from that site:
Understanding Vitamin D Cholecalciferol
The high rate of natural production of vitamin D3 cholecalciferol in the skin is the single most important fact every person should know about vitamin D—a fact that has profound implications for the natural human condition.
Technically not a "vitamin," vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that targets over 200 genes in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.
Vitamin D's influence on key biological functions vital to one's health and well-being mandates that vitamin D no longer be ignored by the health care industry nor by individuals striving to achieve and maintain a greater state of health.
Sunshine and Your Health
If one regularly avoids sunlight exposure, research indicates a necessity to supplement with at least 5,000 units (IU) of vitamin D daily. To obtain this amount from milk one would need to consume 40 glasses. With a multivitamin as much as 10 tablets would be necessary. Neither is advisable.
The skin produces approximately 20,000 IU vitamin D in response 20–30 minutes summer sun exposure—100 times more than the US government's recommendation of 200 IU per day!
There are 3 ways to insure adequate levels of vitamin D:
* receive midday sun exposure, exposing as much of the skin as possible.
* use a sun bed (avoiding sunburn).
* have a physician administer a 25-hydroxyvitamin D test and supplement with vitamin D3 cholecalciferol should results reveal an insufficiency (optimal levels are around 50 ng/mL, or 125 nM/L).
