Health Benefits of Tea

Tea: It Does the Body Good

Studies that support the health benefits of tea drinking keep filling the headlines. There’s simply no denying that a daily spot of tea does the body good.

Even though researchers can’t quite agree on every aspect, I’m sold on the fact that a few cups a day will do its best to protect me from heart disease, a stroke, cancer, and more.

What Makes Tea Good for the Body?

Tea contains high levels of antioxidants, some of which are called polyphenols, flavonoids, and catechins, and all of which take on the “free radicals” in the body and prevent them from harming the healthy cells on board.

In other words, sending in antioxidants is disease prevention in its finest form. Antioxidants are ready and waiting not only in teas but also in several fruits, vegetables, nuts, meats, and even wines (see my health benefits of wine article).

If that were not enough, tea also contains flouride which benefits your teeth and has bacteria killing properties which helps control bad breath and the formation of plaque.

Are All Teas Equally Good for the Body?

This is a question researchers are still squabbling over. Does green tea have more antioxidants than black tea? Should I drink instant tea or loose leaf tea for better health benefits? Is hot tea better than iced tea? And here’s what it comes down to:

• Higher quality teas may have more catechin antioxidants than lower quality teas.
• White tea has more antioxidants than any other tea.
• Green tea has more catechin antioxidants than black tea since black tea goes through more processing.
• Unfermented rooibos tea has more polyphenol antioxidants than fermented rooibos.
• Freshly brewed teas have more polyphenol antioxidants than instant or bottled teas.
• More researchers seem to agree that brewed (cold or hot) or caffeinated tea has more antioxidants than instant teas.

Here’s a short preview of the hundreds of recent studies that boast the health benefits of tea and its antioxidants:
