Get on the Vitamin D Train

According to New York Times 85 percent of people are not getting enough vitamin D. Which is not good because it is something that we can get for free through the sun? Now you may be asking what is vitamin D? Vitamin D is a fat soluble, which means it can only be absorbed when consumed with foods that contain fat. According to dictionary.com vitamin D “is any of a group of vitamins found in liver and fish oils, essential for the absorption of calcium and the prevention of rickets in children and osteomalacia in adults”. Vitamin D is usually produced in the skin of human and animals under the influence of solar or ultraviolet radiation. In plants it can be produced from provitamin ergo sterol. Irradiation of ergo sterol leads to the formation of ergocalciferol (vitamin D2). Vitamins D2 and D3 are absorbed from food in the small intestine and transferred to the liver. It was found that vitamin D provides adsorption of calcium and phosphorus in the small intestine. Vitamin D enhances the adsorption of the phosphorus in the kidneys. It also enhances the retention of calcium in bone tissue. It was also found that vitamin D could have a protective role against various tumors, like cancer of the colon and breast cancer. Vitamin D is also known as sunshine vitamin. It is produced by the body as a response to sun exposure. It can also be consumed in food or supplements. Some of the role of these vitamins is to maintain the health of bones and teeth, supports health of immune system, brain and nervous system, regulate insulin levels and aid diabetes management, supports lung functions and heart. Benefits are that it helps fight disease, reduces depressions and boost weight loss.

The sources were vitamin D can be found are in salmon, sardines, shrimp, milk cereal, egg yolk, yogurt, orange juice. There are three sources of vitamin D, one is exposure to sunlight. It’s important to realize that although we live in a generally sunny country, many things can affect the amount of exposure to UV radiation and vitamin D synthesis in the body. These include – season, time of day, length of day, cloud cover, smog, skin melanin content, and sunscreen. Also, UVB radiation does not penetrate glass, so exposure to sunshine indoors through a window does not produce vitamin D. The factors that affect vitamin D levels make it difficult to provide general guidelines on adequate amounts of sun exposure. It has been suggested by some vitamin D researchers, for example, that approximately 5–30 minutes of sun exposure between 10 AM and 3 PM at least twice a week to the face, arms, legs, or back without sunscreen usually lead to sufficient vitamin D synthesis.
The need for vitamin D continues into childhood where growing children require VitaminD for optimal bone mineralization especially during times when sunlight exposure is limited. As a result of the many benefits of increasing one’s daily consumption of Vitamin D, would definitely consider increasing the DRI for Vitamin D. Vitamin D is vital for calcium absorption, bone health, immunity, the expression of over 200 genes, and the prevention of many chronic diseases such as cancer, arthritis, heart disease, and high blood pressure. Vitamin D can be obtained mostly through sunlight and radiation rays, but food sources such as milk and cold-water fish are also very important to maintaining adequate levels of Vitamin D in the body. Some foods are also Vitamin D fortified for example, orange juice, in order to help people reach the DR. There was an experiment done that did prove that vitamin D inhibits metastasis of large intestine tumor cells. There is controversy related to Vitamin D supplements. Many doctors do not test vitaminD levels. Therefore, most Vitamin D deficiencies go undiagnosed. There is a push for Vitamin Dlevels to be routinely checked and supplements used to treat those lacking. Many pediatricians believe that every child they check is going to be low, so therefore every parent should be encouraged to give their children Vitamin D supplements and there would be no need to check their levels first. There is not much controversy in the fact that Vitamin D is a worldwide deficiency problem. There are still people that question the lack of control trials that have been done to support the studies noting the benefits of Vitamin D.

Vitamin D has many functions in the human body. One of vitamin D roles is to help absorb calcium. Vitamin D, along with calcium, helps build bones and keep bones strong and healthy. Also, vitamin D blocks the release of parathyroid hormone. This hormone reabsorbs bone tissue, which makes bones thin and brittle.
