Vitamin D, sunshine vitamin is fat-soluble nutrient that is not only in natural foods, but is also produced by the body when skin is exposed to ultraviolet (UV) rays. And it may come as a surprise to many to know that this vitamin only has the potential not only to strengthen our bones and teeth, but is also known to protect against cancer, tuberculosis, diabetes, arthritis, flu and even the common cold.
Ironically, however, that despite access to the outside, most people do not receive sufficient quantities. Changes in blood concentrations can lead thanks to seasonal conditions, where the protective clothing and cold the angle of the sun in the winter sky limit the amount of UV light that actually reaches the skin. In addition, the color and food intake through diet or vitamin supplements affect all the vitamin D in the body.
Surprisingly, when the sun's rays hit the skin, the body converts cholesterol into vitamin D-like compound, and it takes only 10-15 minutes of exposure to the hands or feet to synthesize adequate daily intake of nutrients. However, the place where a person lives has a significant effect on the skin more direct exposure to UV rays.
More residents of tropical areas is usually an adequate level of vitamin D. However, studies show that people throughout the industrial world are not so lucky. Individuals with more temperate and colder climates do not reach the levels currently recommended to protect the health of bones and teeth, not to mention a higher content of research that has shown to provide additional benefits for health and cancer prevention.
It is not too difficult to obtain the required levels if you happen to be white with their body exposed to the sun with nothing but a bathing suit in the mid-day mid-summer no matter where you are you are. The truth is that the human body can produce between 10,000 and 12,000 international units (IU) of vitamin D from a half-hour summer exhibition in the sun.
Unfortunately, when the warnings reactivity from dermatologists on the prevention of skin cancer by limiting sun and use sunscreen, not to mention wear a hat, long sleeves and long pants clothing, most individuals are unable to take advantage of this cheap and most efficient source of this important vitamin.
Recommended Foods and other food sources of vitamin D are dairy products, especially in fortified milk, meat, fatty fish such as tuna, salmon, sardines and mackerel, and leafy green vegetables like spinach and broccoli, dry cereal or cereal bars and cereals, a variety of dietary supplements.
When vitamin D deficiencies are usually the result of the lack of presence in food availability or access to the growing needs of the body and the losses increased by the secretion of the body, reduced absorption and / or use of the body where the kidneys are not able to convert vitamin D into active hormone. Or, if anyone can get enough vitamin D from inside the digestive system, and, of course, in situations where limited exposure to sunlight.
Daily diet that is deficient in vitamin D is usually associated with a milk allergy, lactose intolerance, and strict vegetarianism. Even babies who are fed only breast milk will also receive inadequate amounts of vitamin D, unless otherwise receive adequate levels of vitamin D.
In children, vitamin D deficiency causes a condition known as rickets, a bone disease which is not proper mineralization of bone tissue. Rickets results in soft bones and skeletal deformities. Surprisingly, prolonged exclusive breastfeeding without vitamin D supplementation is one of the main reasons to re-emerge, and rickets. Other reasons may include the widespread use of sunscreen, or even greater use of day care services, which can lead to a reduction in outdoor activities, and lack of sun exposure in young children.
In adults, vitamin D deficiency can cause osteomalacia, which results in muscle weakness, and a weak bone structure. Low levels of vitamin D may also increase the risk of developing all forms of cancer.
Unfortunately, provides enough vitamin D from natural food sources is not an easy task. Founded in the RDA is 200 IU, but many researchers agree that the number should fall somewhere between 1000 and 2000 IU IU, to reduce the risk of cancer and boost the immune system. Thus, the majority of people, maintaining healthy blood levels of this important vitamin required balance of consuming vitamin D fortified foods and to ensure adequate exposure to sunlight.
