Did you ever notice that there are less colds and flu in summer? That is because there is usually stronger sunshine which stimulates Vitamin D production in the skin. Vitamin D is more important than most people realize for protection against colds and flu and is an influential preventative for a wide assortment of diseases like cancer, diabetes, auto-immune diseases, heart disease and depression. Research in recent decades shows the deficit of Vitamin D in the body has more far reaching effects than most people realized.
In the American Journal of Clinical Nutrition, Dr. John Cannell and his team report that T-cells that the body generates to fight infection are more efficient and active when bound with Vitamin D. Vitamin D is an integral part of the body's defense system. When foreign agents enter the body that trigger an immune response a chain reaction starts.
Vitamins Immune System
First, invasive microorganisms are released from the blood into the walls of the intestine which causes the release of Immunoglobulin A (IgA). In adults there are about 30 receptors called Peyer's patches in the lower part of the small intestine which release B-lymphocytes into the blood and lymph system. Through a series of hormonal signaling dendritic cells, macrophages and finally T-lymphocytes are released.
The most efficient killers of invasive microorganisms are the T-lymphocytes. When these T-cells recognize a foreign invader, like a bacteria or a virus, they send out a hormonal signal to the Vitamin D receptor gene. This activating signal stimulates the VDR gene to produce a DVR protein which causes Vitamin D to attach to the T-cell. This whole process then produces a hormone called PLC-gamma one protein which turbo charges the T-cell to do an efficient job to fight the infection. Without Vitamin D, the T-cells are less active and stimulated by infective agents.
Dr. Cannell and his team also showed that Vitamin D help protect against colds and the flu by stimulating production of antibacterial peptides that keep the T-cells alert, providing an early warning system against invaders.
Vitamin D is not all created equal. Obviously, Vitamin D from the sun is the most effective and natural. The form of Vitamin D generated in your body from sun exposure, particularly UV-B rays in sunlight, performs like a pro-hormone in the skin, converting quickly into 25-hydroxyvitamin D, or Vitamin D3. People in northern climates are the most prone to Vitamin D deficiency as there is less sun exposure, especially between September and mid to the end of April. Dr. Cannell further postulates that colds and flu may only be a symptom of Vitamin D deficiency, especially in areas above and below 30 degrees latitude.
Since Vitamin D is a fat soluble vitamin, the recommended daily allowances for different age groups has been thought to be low enough not to cause dangerous levels of accumulation in the body. Recent research has shown these levels to be woefully inadequate. The latest research shows that 35 IU's of Vitamin D3 (cholecalciferol) is the optimum dosage per pound of body weight in all individuals, including children, pregnant women and the elderly.
The only way to determine an accurate dosage for you, is to have your blood tested. Your health professional can advise you on your proper individual dosage. According to studies, an ideal year-round Vitamin D3 level is 50-65 ng/ml.
If Dr. Cannell is correct, as his study shows, you can see the end to colds, flu and other health conditions, while the rest of the world is sneezing, coughing and blowing their nose. It's a good thing that Vitamin D is so inexpensive. Maybe it's time to buy shares in the tissue companies.
