Fight cold + flu season by drinking tea.

With so many people concerned about the cold & flu season this year, we thought it would be a good time to share some info on how drinking tea can be a great help getting through the winter season. It is very common for people to ask about the health benefits of tea, and while we never suggest that tea can cure anything, we do want to keep you informed on some of the studies relating to health benefits of drinking tea.

Studies show that drinking tea may be beneficial for preventing colds and flu for several reasons. Different kinds of tea have different associated health benefits.  What follows below highlights some positive aspects of green tea, black tea and white tea.

For this post we will focus on three tea health benefits, specifically :

– Tea’s stimulating action on the immune system.

– Tea’s potent antiviral effect.

– Tea’s potent antibacterial effect.

Tea + a healthy immune system

Studies suggest that drinking green tea stimulates the immune system to work harder and better against fighiting foreign matter. This effect is due to a very special antioxidant polyphenol called epigallocatechin gallate (EGCG). There are very high levels of EGCG in green tea – these antioxidants encourage the production of white blood cells which the immune system produces to fight infection and foreign materials.

Additionally, EGCG encourages the increased reproduction of the immune systems B-cells, which is important because just a single B-cell produces thousands and thousands of antibodies, each programmed to attack specific invaders.

Overall, the data suggests that drinking tea can “rev-up” you immune system and perhaps help you fend off some of the nasty stuff that drops in to say hello over the winter.

Tea + Viruses

The same antioxidant polyphenols that boost your immune system are also potent antiviral agents. The catechins in green tea (and their black tea counterparts called theaflavins) inhibit virus reproduction by preventing the attachment of the virus to your cells. If a virus can not successfully “hijack” your cells then chances are you will not develop the nasty cold or flu that the virus can bring.

Overall, the data suggests that drinking both green tea or black tea may be a good way to prevent the spread of a virus such as influenza. Recent studies in South Korea suggest that these antioxidant polyphenols are effective against specific strains of the influenza virus, including H1N1.

Tea + Bacteria

As if the antiviral aspect wasn’t good enough, studies also suggest that green tea and white tea are powerful enemies of bad bacteria in your body. Studies suggest that the combination of EGCG and another polyphenol antioxidant called epigallocatechin (EGC – the same antioxidant found in pomegranate) are a potent tag team which can have devastating effects on the growth of bacteria. Additionally, drinking green tea increases the levels of good intestinal bacteria like acidophilus!

Disclaimer: While we never try to offer medical advice on the benefits of tea, we just so happen to think it’s a great benefit that our favorite beverage just happens to have an ever growing body of positive health findings. We are always asked how tea benefits health, how healthy is green tea, is green tea healthier than white tea….we want to fulfill your desire for information on tea health benefits and will do so in this blog as well as on our twitter and facebook pages.
