The importance of vitamin D
Vitamin D is one of the most neglected nutrient and less now understood; and take into the body adequate levels of this element, can prevent and cure a long list of diseases.
It is estimated that of the 30,000 genes in the human body, vitamin D may influence 3000. So you can participate in the development of many ailments. However, in the US alone 77% of the population is deficient in this nutrient.
Vitamin D is a steroid hormone that anyone can get through exposure to sunlight, certain foods and dietary supplements. While there are several types, is beneficial vitamin D3.
HOW TO PREVENT DISEASE
In more than 200 epidemiological studies have confirmed theories linking vitamin D to certain cancers. More than 600,000 cases of breast and colorectal cancer could be prevented with increased nutrient levels. Well could prevent 16 different cancers, including pancreatic, ovarian, lung, prostate and skin. Furthermore, several studies attest that consumption of vitamin D lowers the overall cancer risk by 60%.
Cancer deaths are preventable by 30% by increasing the dose of vitamin D in the population. Women with fair skin who have spent more time in the sun are 50% less likely to develop breast cancer in advanced degree than those who took less sun.
But how do these phenomena be explained? First, vitamin D increases the self-destruction of cells that have mutated, and that could become cancer. It also reduces the spread and reproduction of cancer cells, as well as the growth of new blood vessels from existing ones, which is one of the processes leading to awaken the dormant tumors.
Vitamin D fighting colds and flu; even regulate the expression of genes that influence the immune system attacking and destroying bacteria or viruses. In fact, it is very rare for someone with good nutrient levels fall ill with flu.
TAKE THE SUN IS GOOD
The single wavelength that produces vitamin D in the body are the UVB rays. These only enter the atmosphere when the sun is at an angle of more than 50 ° to the horizon. Below this position, the ozone layer reflects only UVB but passes UVA. The notion that we should avoid the sun and always use protection to prevent skin cancer, is a myth.
In fact, controlled exposure to UV rays is one of the best ways to protect against cancer. Of course, sunburns are dangerous and not recommended to get exposed to the rays at this point. There is a form of skin cancer unrelated to melanoma, which is not as dangerous as the other.
Deaths associated with this cancer are 1500 per year in the US. However, nearly 300,000 people die each year from cancers of all kinds, because their vitamin D levels are too low. In fact, until recently, most sunscreens blocked UVB which are those which produce vitamin D and no UVA, which are harmful.
The sun is ideal for this element source, but people living in the northern hemisphere do not have enough sunlight half the year. In this case, experts suggest taking vitamin D supplements or using appropriate tanning beds. Which should not use are those that use a magnetic ballast; you will know by the sound it produces, a strong sharp sound. Electronic beds do not emit the same amount of the other harmful radiation.
Moreover, you should also look at the types of bulbs that are being used; some have the range of UVB and UVA rays adapted so you get more than the first, which are the beneficiosos- even more than the sun. Thus, this type of radiation is more controlled exposure to natural sunlight. Despite these explanations, we must clarify that it is not safe for the World Health Organization solar tanning bed.
To optimize your vitamin D levels and get a healthy tan, it is important that in the early days limit your sun exposure, to allow your skin cells (melanocytes) recover and produce pigmentation protection. The darker your dermis becomes more tanned-and quedar- want more time can be in the sun. If you are a person with dark skin and sun shots very early or late, your first session can be up to ½ hour.
Finally, another expert recommendations not to bathe with soap for at least the next hour being in the sun, except in the armpits and groin. This is because the body takes time to convert the radiation of UVB rays into vitamin D3. Anyway, not to lose the benefits you can wash with water only.
