The Results of a Study published in the Feb 23 issue of Internal Medicine offer Strong Support for
Vitamin D’s Role in reducing the risk of colds and the flu. After examining the relationship between vitamin D and Respiratory illness in nearly 19,000 adolescents and adults, researchers found that those with the lowest blood levels of the vitamin were about 40 percent more likely to have suffered a recent respiratory infection than those with the highest levels.
The association was even stronger among individuals with pre-existing Lung ailments. Among study, volunteers with COPD , including Emphysema, researchers found that those with low blood levels of vitamin D were twice as likely to have experienced recent respiratory infections. Asthma patients with the lowest vitamin D levels were Five Times more likely to have suffered an infection than those with the highest level.
In laboratory experiments, the vitamin has been shown to dramatically enhance the germ-killing potential of white blood cells.
This Action is most apparent in the Lining of the Respiratory Tract, which plays a critical role in protecting the Throat, Lungs and Sinuses from invasion by disease causing viruses and bacteria.
While Vitamin D helps the body fend off colds and the flu, it also appears to arm the immune system against more serious illnesses, including cancer. Harvard investigators reported Adequate intakes of vitamin D have long been associated with a lower risk of colorectal cancer. Findings from several small clinical trials suggest that vitamin D also may thwart the progression of prostate cancer. In men diagnosed with the disease, supplementation was shown to slow the rise in blood levels of prostate specific antigen (PSA) , a biological marker for the condition. In a four-year study of more than 1,000 women , researchers at Creighton University found that those who took daily doses of calcium plus 1,100 international units of vitamin D experienced a 60 percent reduction in Breast Cancer compared to those taking placebo pills.
Vitamin D deficiency was once believed to be relatively rare among Americans, but recent epidemiological studies suggest that the condition is becoming a Widespread Problem in the United States. With age, however, the skin manufactures vitamin D less efficiently, leaving many older people at risk for a deficiency. Although some physicians now suggest daily does of at least 1,000 international units to 2,000international units for most adults, the daily recommended allowance is substantially lower.
Getting adequate amounts of Vitamin D may help prevent colds and the flu during the darker days of winter. Even better it could reduce the risk of developing other more serious illnesses all year long.
But Please check first with your doctor to test your blood level for Vitamin D
