Staying Ahead of Cold and Flu Season


Staying Ahead of Cold and Flu Season


It’s that time of the year again: cold and flu season. Easily one of the more unpleasant experiences to have during the fall, getting sick is surprisingly common and it simply doesn’t need to be. There are plenty of things we can do to prevent coming down with the cold or flu this year.
Washing your hands often and avoiding touching your face, nose, eyes or mouth can help prevent the spread of germs. Even sanitizing doorknobs, handles, keyboards, remotes, keys, and other items you frequently touch can help to keep the cold and flu contained…but what happens when those pathogens are introduced into the body?
Even if you’re prepared for flu season this year, others may not be quite as thoughtful when it comes to flu prevention. The average sneeze travels at approximately 100 miles per hour and carries over 100,000 germs a sneeze. With autumn on its way, now is the time to prime your immune system:
Vitamin A stimulates the production and activity of white blood cells and the endothelial cells that line the body’s interior surfaces which offer primary protection from illness and infection. In its pure form, Vitamin A can be toxic, but stored as Beta Carotene, the body will only convert and use what it needs. The remaining Beta Carotene works as an antioxidant in the body fighting free radicals. Vitamin A must be replaced daily, so make sure this is a part of your everyday regimen.
Vitamin C is well-known for its immunity benefits. Taking Vitamin C regularly can boost immunity, and people who take extra doses of Vitamin C report recovering from colds and the flu much faster than others. Even levels of 200 mg/day increase levels of immunoglobulin, which are proteins that act as disease-fighting antibodies. Vitamin C is often stored as Ascorbic Acid, which also increases the absorption of other vitamins you may be taking.
Vitamin D is best known as a precursor to calcium absorption and bone health, but the Harvard School of Public Health states that vitamin D also obstructs some of the damaging inflammatory response of some white blood cells. This can make a world of difference for those suffering swollen lymph nodes or raw, scratchy throats this cold and flu season. 
Not only can Vitamin E can also help support your body’s healing abilities, but it can also increase immunity response to pathogens. Studies by the Nutritional Immunology Laboratory preformed two separate studies around vitamin E supplementation. His first study found elderly patients who took vitamin E regularly were less likely to come down with colds or upper respiratory infections. The study was repeated again with young men as test subjects who also showed increased immune response.
Selenium is a trace mineral which is reduced into selenoproteins by the body. In this form, it can not only  supports cellular immune response and cell membrane health, but it can also aid the body facilitate antioxidant enzymes. This means selenium can play a substantial role in helping the body fight off pathogens and free radicals.
Regular amounts of zinc can help ensure your T-cells and other immune cells are able to function properly and defend the body. Zinc deficiency or zinc overdose can inhibit your immune response. Meeting your Recommended Daily Allowance (RDA) can help you avoid developing a deficiency of the trace element, zinc.
