Study: Vitamin D could prevent common cold 研究:維生素D可預防感冒

Sun, Mar 19, 2017 - Page 9

A study announced on Feb. 16 indicates that taking Vitamin D supplements can prevent respiratory tract infections such as colds and influenza, reigniting the debate on the effectiveness of non-prescription dietary supplements.

The study, in the British medical publication BMJ, claims to have discovered, for the first time, “clear evidence” of a link between Vitamin D and influenza, after evaluating the different results from a total of 25 clinical trials in 14 countries.

This is especially apparent for people suffering from Vitamin D deficiency. Vitamin D can be absorbed through a number of foods. The human body is also able to synthesize Vitamin D endogenously when ultraviolet rays from sunlight make contact with the skin.

Many people have Vitamin D deficiency, especially residents of areas of climates of low levels of sunlight.

For many years, scientific studies have come up with mixed conclusions about Vitamin D, with some finding that low levels of Vitamin D can increase the risk of bone fracture, cardiovascular disease, colorectal cancer, diabetes, depression, Alzheimer’s disease and death. Other studies, however, showed that it was impossible to prove a link between Vitamin D and risk of disease.
