More than half of the World’s Population Gets Insufficient Vitamin D: Experts Says

Vitamin D is no doubt one of the most important items for our body but are we getting the desired amount of vitamin D?

Anthony NormanSome of the experts of Vitamin D have answered this question and it is ‘No’ for majority of the population. In the July 2010 issue of Endocrine Today, Anthony Norman, a distinguished professor emeritus of biochemistry and biomedical sciences and an international expert on vitamin D notified that more than half of people in North America and Western Europe gets insufficient amount of Vitamin D.

The Vitamin is actually present in very few foods like cod liver oil, fish and eggs, in the other foods like orange juice, milk, yogurts’ and other breakfast items it is present in the fortified form. According to Norman “There is a wide consensus among scientists that the relative daily intake of vitamin D should be increased to 2,000 to 4,000 IU for most adults” and further “A 2000 IU daily intake can be achieved by a combination of sunshine, food, supplements, and possibly even limited tanning exposure”.

Norman has been researching on Vitamin D for at least 50 years and his observation for the Vitamin D intake can’t prove to be doubtful, his laboratory has proven many useful facts regarding Vitamin D and these can effectively help humans in solving different problems of life.

Winter: Diminishing Vitamin D Levels May Harm Heart Health

heart attackAccording to the US researchers, the lack of sunshine during winter may cause diminishing vitamin D levels in the body and lead to heart woes.

Sunshine is needed to the body to produce vitamin D, due to less daylight and spending more time indoors in winter can slowdown this process.

Study author Sue Penckofer, who is a professor at the Marcella Niehoff School of Nursing at Loyola University in Chicago, says in a university news release: “Chronic vitamin D deficiency may become the cause ofhigh blood pressure, heart disease and metabolic syndrome.”

In their study, Sue and team reviewed many such studies that associated heart disease to vitamin D deficiency. According to these studies, severe heart disease or heart death rates are 30 to 50 percent higher in the patients with sun-deprived heart diseases.

Vitamin C, E Supplements not Helpful to Avoid Cancer

cancer.jpgSoon after the two studies that discounted the helpfulness of vitamin B, folic acid, vitamin D and calcium supplements for cancer prevention, now U.S researchers report that even vitamin C and E supplements are not helpful to avoid cancer.

The same researchers have recently reported that vitamin C and E supplements are not beneficial to prevent even heart disease.

Dr. Howard Sesso (one of the study’s authors), who is an assistant professor of medicine in the division of preventive medicine at Brigham and Women’s Hospital in Boston, says: “We find no compelling evidence to take vitamin E or C at least in the context of two very common outcomes i.e. cardioprotection and chemoprevention.”

Effects of Sun Bathing

Take pleasure in the sun considered be the most delightful way to spend a holiday or even just one hour or two. But almost all of us have suffered from sunburn at some time in his/her lives. This condition is extremely itchy and painful. Too much time spend under the sun can also lead to headaches, skin pain and also increase the risk of serious diseases such as cancer.Although researchers have linked vitamin D deficiency with cancer and other health conditions like osteoporosis and osteomalacia, hypertension, heart diseases and diabetes in adults and rickets in children. It has been recorded that each year fifty to sixty thousands individuals in U.S. die prematurely from cancers caused by lack of vitamin D

Though previous studies have established that vitamin D and sun exposure can protect against infectious diseases but according to the FDA, approximately 1 in 5 people in the U. S. will be diagnosed with skin cancer at some point in their lives. The most important, preventable cause of skin cancer is extreme exposure to the sun rays.

Exposure to ultraviolet radiation is known to be an important cause of skin cancers. As these rays induce DNA damage, however for the non-melanoma skin cancers, cumulative sun exposure is believed to be essential. The prevalence of all skin cancers is rising day by day.
