2. Vitamin D- A group of steroids; resistant to heat, oxidation, acids, and bases; stored in liver, skin, brain, spleen, and bones. Promotes absorption of calcium and phosphorous; promotes development of teeth and bones. Sources: produces in skin exposed to ultraviolet light; in milk; egg yolk; fish liver oils; fortified foods. Excess: Diarrhea calcification of soft tissues, renal damage. Deficienceis: Rickets,bone decalcification and weakening.
How can anyone have a deﬁciency? Despite advances in vitamin research over the last century, millions of people around the globe still suffer from vitamin deﬁciency diseases. In the United States, the plentiful and
Vitamin D plays a critical role in many normal bodily functions as well as fighting against a wide number of health barriers. In an article by Jacqueline Kanopa, studies revealed that exposure to ultraviolet rays play a huge part in Vitamin D production, as well as having preventative effects on a disorder known as rickets; which leads to weakened bones due to lack of Vitamin D. This study supports the belief that exposure to UV rays play a critical role in Vitamin D production, and can be beneficial to those prone to certain
Tanning salons also state that some UV radiation is needed for the manufacturing of vitamin D. Vitamin D certifies that a constant level of calcium remains in the blood and controls its absorption. In an advertisement for tanning equipment, one tanning bed company, The Beach House Tanning, claims that the sun is the only source of Vitamin D (http://www.beachouse.com/tanning_benefits.htm). However, vitamin D is also found in foods such as dairy products, cereal, and fish (http://shrike.depaul.edu/~vbard/vitdpg.html), and it takes far less UV radiation to obtain the necessary amount of vitamin D than it does to get a suntan (http://www.fda.gov/cdrh/tanning.html).
In most subjects, sun exposure is the primary determinant of vitamin D status, accounting for 80-90% of the vitamin D body stores. Cholecalciferol (vitamin D3) is synthesized in the skin and found in fatty fish and mammals, whereas ergocalciferol (vitamin D2) comes from yeasts and plants. Vitamin D supplements may contain either vitamin D2 or D3. Previously, the two vitamin D metabolites were considered to have an equal potency, but recent studies have suggested that vitamin D2 may be inferior to vitamin D3 in the treatment of vitamin D insufficiency [Romagnoli et al. 2008].
Vitamin intake is a commonly overlooked necessity in basic nutritional health. What most people do not know is that certain vitamin deficiencies can cause many health risks and problems. Many people believe that are getting all the vitamins they need from their diet, however most of the time they are not. One of the most common vitamin deficiencies is the low intake of Vitamin D. There are some vitamins that are produced by the body such as vitamin K; however some of the most important vitamins are not produced by the body. Vitamin D is one of the vitamins that our body needs to function correctly that is not naturally produced by the body. Vitamin D can be consumed through
There are potential dangers that are associated with this issue. When students’ have been using the main oval and the basketball courts and are idle for more then a few hours per day, it can potentially cause skin cancer and sunburns. Since Australia is increasingly getting warmer per year, and had one of the highest rates of skin cancer, being prone to sunburns and skin cancer is quite inevitable. The possible hazards with excessive amounts of sun exposure include, sunburns, skin cancer and in a worst-case scenario may include, melanoma. If students are outdoors more often and refuse to use any hats and applying sun safety products provided by teachers, they may have a chance of getting sunburns, which may limit their
However, due to the many technological advances that we have today, we are able to live in places where our skin pigmentation has no accord with the UV radiation of our current environment; this lack of harmony results in many mental and physical deficiencies, the most common of which is vitamin D
Not only is the sun important for trees and plants, it also has a great influence on human beings. The rays of the sun are filled with vitamin D which is essential for healthy bones and it also manages calcium in our blood and cells. Not having enough vitamin D in our body will cause many problems such as cardiovascular disease, cancer, and the bones might even become brittle or soft. Vitamin D deficiency is very common. A drug used for maintaining the correct amount of Vitamin D in our body is Calciferol.
The most common cause of sun allergy is heredity influencing the amount of sunlight or ultraviolet rays (UV) our skin can absorb comfortably- too much unprotected sun results in sunburn leading to sun allergy reactions. Sun allergy affects all skin tones – it’s the level of sensitivity to the sun that changes the severity of itchy rashes or scaly patches due to a higher level of photosensitivity, called polymorphous light eruptions.
Vitamin D is a bit mystifying--the only vitamin that's also a hormone, and the only vitamin people don't have to consume from food. You manufacture it when your skin is exposed to the sun. See how you do on this quick quiz.
Premature aging is one main effect of sun exposure. Becoming an old looking, wrinkly person is the last thing people look forward to, but did you know that the average
Vitamin D is responsible for regulating the passage of calcium (Ca 2+ ) to the bones. Therefore, if vitamin D is missing, this step does not occur and the bones begin to weaken and curl causing irreversible malformations: rickets. This disease especially affects children.
A study published in Archives of Internal Medicine found that 75 percent or more of American teens and adults are deficient in Vitamin D. That is why we have so many serious illnesses, like cancer, diabetes and heart disease (Huff, 2010).
