Research clearly show that as many as three out of four Americans suffer from Vitamin D deficiency. A study published in 2009 in the Archives of Internal Medicine (a leading scientific journal), identified that 70% of Caucasians, 90% of Hispanics and 97% of African Americans in the US have inadequate blood levels of Vitamin D. Undoubtedly, it’s considered to be the most prevalent medical condition in the world, influencing over one billion persons and we now have research showing just how crucial Vitamin D is to well being.
In our world of sunscreen, hats, indoor living, and nominal sun exposure, we are in effect producing a greater dilemma than sun exposure.
U.S. and Norwegian researchers have determined that people who live in higher latitudes are further prone to Vitamin D deficiency and more susceptible to developing typical cancers and succumbing of them. The University of Maryland put out an article that shows all the problems that Vitamin D deficiency induces.
Major Ailments Caused by Vitamin D Deficiency (and there are more)
· Obesity
· Cancers -colorectal and pancreatic primarily
· Heart Disease -The number one killer by far
· High Blood Pressure - causes strokes
· Diabetes
· Multiple Sclerosis
· Osteoporosis
· Parathyroid Issues
· Depression
So what is killing America?

What is Vitamin D and how much do you need?
Vitamin D is a group of fat-soluble seco-steroids. In humans, Vitamin D is unique both because it operates as a pro-hormone and because when sun exposure is ideal, the body can synthesize it (as Vitamin D3). There are two types of VitaminD ; ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Some investigating implies that cholecalciferol is more effective at improving levels of vitamin D in the blood. So the greater absorbed vitamin D for our bodies is the kind that our body makes (D3) because it is better utilized in our bodies through our bloodstream. The most beneficial way to determine whether or not you are lacking is to have your Vitamin D blood levels measured and re-supply as required.
The new minimum reference intakes for vitamin D: (These are the minimum we should have per day.)
0-12 months: 400 IU/day
1 - 70 years of age: 600 IU/day
71+ years of age: 800 IU/day
Pregnant/lactating: 600 IU/day
0-12 months: 400 IU/day
Tolerable upper intake levels of vitamin D.
The Tolerable Upper Intake Level is defined as "the highest average daily intake of a nutrient that is likely to pose no risk of adverse health effects for nearly all persons in the general population". Although tolerable upper intake levels are believed to be safe, information on the long term effects is incomplete and these levels of intake are not necessarily recommended. Which is actually part of the problem.
0-6 months of age: 1,000 IU
6-12 months of age: 1,500 IU
1-3 years of age: 2,500 IU
4-8 years of age: 3,000 IU
9-71+ years of age: 4,000 IU
Pregnant/lactating: 4,000 IU[39]
Some schools of thought believe 4000-12000 is optimum.
In healthy adults, sustained intake of more than 1250 micrograms/day (50,000 IU) can produce overt toxicity after several months of use.
Direct exposure to sunlight for extensive periods of time does not commonly cause vitamin D toxicity. Within about 20 minutes of ultraviolet exposure in light skinned persons (3-6 times longer for pigmented skin), the levels of vitamin D precursors produced in the skin accomplish an equilibrium, and any extra vitamin D that is produced is degraded. According to a handful of sources, endogenous production with full body exposure to sunlight is approximately 250 µg (10,000 IU) per day.
So long story made short. If you get 20 minutes to 120 minutes of unprotected sun exposure (depending on your skin pigment) you get 10,000IU/Day vitamin D and the rest is degraded, meaning to be toxic you would need another 40,000IU/day to become toxic over several MONTHS of prolonged use . Unheard of! So what’s your excuse for not getting more sun/ UV exposure? Oh yeah, skin cancer.
So what are the Cons to prolonged sun exposure and un-protected sunbathing?
No matter what you may hear at tanning salons, the cumulative damage caused by UV radiation can lead to untimely skin aging wrinkles, lax skin, brown spots, as well as skin cancer.
So really, the major pitfalls of exposure to the sun is cosmetic. Are we really that vain as a contemporary culture that wrinkles, relaxed skin and brown spots are the true evils of sun exposure? No, it must be the cancer then. The most widespread form of skin cancer is Basal Cell Carcinoma. We are going to focus on that, because lets face it, It’s the big “C” and a buzz-word that scares nearly all of us. Besides, I assume the risks from under-exposure to the sun ie, hunched backs, MS, Diabetes, Heart Disease (number 1 killer) and depression pales in comparison to the common alternatives of splotchy and sagging skin.
What are the main causes of Basal Cell Carcinoma?
The Mayo clinic Says:
· Chronic sun exposure
· Exposure to radiation
· Fair skin
· Your sex. Men are more likely to develop basal cell carcinoma than women are
· Your age. Higher incidence in people age 50 or older
· A personal or family history of skin cancer
· Immune-suppressing drugs. Taking medications that suppress your immune system, significantly increases your risk of skin cancer.
· Exposure to arsenic
· Inherited syndromes that cause skin cancer. Gorlin-Goltz Syndrome and Xeroderma Pigmentosum
So excluding drugs, radiation exposure, arsenic and unheard of syndromes.... Chronic Sun Exposure stands out as the most common predicament.
What is chronic sun exposure?
Chronic sun exposure is completely subjective to who identifies it. Some say 30 minutes a day, but most say lengthy periods of exposure to the sun resulting in a sunburn. Almost everyone has been sunburned or will get sunburned at some time. Virtually anyone who visits a beach, goes fishing, works in the garden, or plainly is out in the sun, can get sunburned. Improper tanning bed use is also a origin of sunburns. Specialists say, One or more blistering sunburns in childhood or adolescence more than double a individual's chances of forming skin cancer later in life, according to the Skin Cancer Foundation.
Conclusion
Well we’re all screwed then correct? So soak up the sun and fight off all the diabetes and depression we can.... while we still can. That’s silly. But in all seriousness, we have to be careful in the sun, at the level we become sunburned, we then have too much sun. It is suggested that to get the benefits of Vitamin D3 synthesis in the body, we need to be exposed to the sun, but not in high doses. If we are cooking in the sun, developing sunburns, day in and day out, we enhance our risks of getting skin cancer. But if we do not bake in the sun and alternatively get some moderate sun, studies show that we are less probable to produce all those life threatening, and debilitating illnesses. So get out there and get some sun!
