Knowledge about the sources of cancer is ever evolving. Many scientists continually try to discover more concrete links to illustrate factors that contribute to the development of cancer. In more recent years, the health community has come to see a connection between vitamin D deficiency and cancer.
Vitamin D is a vital nutrient for our body. Vitamin D is commonly found in the skin of human but it fully activated by UV rays commonly felt by the sun. This vitamin does not reach its true strength until it transported to the liver and kidneys. It is later converted into a potent form of Vitamin D3. A person can supplement their diet with Vitamin D by eating foods such as fish (cod, salmon, mackerel, tuna), fortified milk, margarine, pudding, breakfast cereals, eggs, beef liver, and cheese.
According the medical data, scientists believe that Vitamin D3 is most beneficial to defend againist cancer. Years of complied scientific data have illustrated an sun exposure on a regular basis has decreased the death rate from particular cancers. It has been observed that the northern area of US are two to three times more at risk of developing cancer, due to limited sun exposure. According to new research published in the American Journal of Clinical Nutrition states that supplements high in Vitamin D can a person’s risk of cancer by 60 to 77 percent.
In a recent study published in the Archive of Internal Medicine, physicians from Harvard observed that premenopausal women, who consumed high levels of calcium and vitamin D had a reduced chance of developing breast cancer compared to women with low vitamin intake. Another study that was conducted at Creighton University, Dr. Joan Lappe observed that there was a 77 percent reduction in the risk of developing various cancers, particularly breast. Lappe believes that the current RDA value is suboptimal and that more Vitamin D3 is necessary for its beneficial affects. Dr. Lappe believes that higher intake of Vitamin D has benefit people from developing cancer, as well as disorders such as Diabetes Type 1, high blood pressure, and multiple sclerosis.
According to some doctors, they have not observed any clinical correlation between Vitamin D supplement and cancer risk. At the National Cancer Institute, Dr. John Milner had conduted a seven year study to test the effects of colon cancer rates on postmenopausal women. Based on his findings, he saw that there was no correlation between development of the colon cancer and vitamin D supplementation. He, however, did not discredit the positive results of physician and scientists who carried varying research. Dr. Milner expressed more concern towards improving lifestyle and entire diet than solely focusing on vitamin supplementation.
Vitamin D is a multifactorial vitamin that effects our body is various ways. Currently, some physicians are finding that this vitamin help to limit the advancement and tumors by limiting the nutrient supply and blood vessel growth. A tumor is usually incapable of growing at an advanced rates if these factors are limited. Most people supplement their diet with Vitamin D, to promote absorption of calcium and phosphorous and helps deposit these mineral in teeth and bones. By promoting calcium absorption, vitamin D helps to form and maintain strong bones. Recent evidence has illustrated that vitamin D also helps maintain a health immune system and helps regulate cell growth and differentiation.
