The Potential Toxicity of Tea Bags:
By Kristie Leong MD If you enjoy sipping a hot cup of tea, you’re not alone. Tea has a long history of being enjoyed for its pleasing taste and aroma. Not only is tea a tasty drink to enjoy, the health benefits are being increasingly recognized. The catechin polyphenols found in green and white teas, are being studied for their potential to not only reduce the risk of certain chronic diseases, but also as a metabolism booster. While a cup of black, white, or green tea provides a healthy alternative to soft drinks, there may be good reason to brew your next cup of tea from loose leaf tea leaves rather than tea bags. Why? It appears that the paper used in the manufacture of commercial tea bags may be a source of a cancer causing chemical known as epichlorohydrin.
Although tea appears to have a variety of health benefits, the same can’t be said for some of the tea bags used to hold it. Here’s what you need to know about the health risks of tea bags made of paper.
The Potential Toxicity of Tea Bags:Many people choose to brew their own tea from loose leaf tea leaves simply because it produces a better tasting cup of tea. The tea leaves packed into commercial tea bags are usually tea fragments and dustings of inferior quality and produce a cup of tea that lacks the full-bodied taste of tea produced from loose leaves. Not only is the taste compromised when tea bags are used, but the health benefits may be reduced by the toxicity of the bag itself.
Many tea bags made of paper are manufactured with a chemical known as epichlorohydrin, a compound used in the manufacture of plastics and used as an insecticide. When this chemical comes into contact with water it forms a chemical called 3-MCPD, a known cancer causing agent. Not only is epichlorohydrin found in paper tea bags, it’s also used in the manufacture of paper coffee filters. While this chemical in and of itself is troubling, when it comes into contact with water as when steeping tea, it becomes of even greater concern because of the cancer causing 3-MCPD it produces.
