We’ve all heard about how potentially beneficial green tea can be. The antioxidants in green tea help the immune system to neutralize toxins, free radicals, that are known to cause cancer. It is said that the same antioxidants in green tea help you look younger. The Japanese people reportedly drink 5 to 10 cups of green tea per day in order to reap all of its benefits. And the list of potential benefits of green tea continues to grow. Green tea can be found in abundance in coffee shops, restaurants, specialty stores, and grocery stores. But despite its healthy reputation, green tea is not tolerated well by everyone, especially when taken in large quantities. Below are some of the more common side effects.
Nausea and upset stomach are some side effects a person may experience after drinking green tea which can be exacerbated by drinking it on an empty stomach. Green tea contains tea tannins which stimulate the stomach to secrete more acid. People with acid reflux are more likely to experience these side effects. One way to get around that is to drink green tea when you have a full stomach.
Iron Deficiency Anemia
The tea tannins also can reduce absorption of iron from the intestines which in some people can lead to iron deficiency anemia. One way to prevent that is to drink tea only between meals so that iron absorption from food is not reduced.
Although the amount of caffeine found in green tea is generally less than that found in coffee, some people still experience heart palpitations and nervousness from the caffeine. Fortunately, oftentimes green tea is available in decaffeinated form which is one way around this problem.
So green tea is not for everyone. Caution should be exercised when drinking green tea, especially if any of the above effects are experienced.
