You may have heard of the many health benefits of green tea. But do you know green tea side effects exist?
The health benefits of green tea have been highly touted in China for centuries. In the west, we are just beginning to realize how much our health can be improved by daily consumption of this miraculous beverage. But even good things can have adverse affects for some people. Although most of us can safely drink three to six cups per day, there are a few green tea side effects you should be aware of.
Caffeine
There is about half as much caffeine in green tea as there is in coffee. Most people find that this substance, labeled a drug because of its stimulating effect, gives them a bit of a lift, and a temporary increase in energy. That?s why we like to start the day with a cup of coffee or tea! Some people, however, are sensitive to caffeine, and should avoid it.
The Federal Drug Administration has determined that caffeine is a safe substance. The American Medical Association agrees that, in moderation, this drug is not dangerous. However some people may find that caffeine makes them jittery, nervous, or edgy. It can increase the symptoms of anxiety, although it has also been shown to be a mood enhancer. It can also cause sleeplessness, especially if ingested late in the day.
While caffeine leads to a temporary increase in blood pressure, there is no evidence that ingesting it can lead to heart disease or hypertension.
Unless you have a noticeable sensitivity to this substance, there is no reason to think that this will be a green tea side effect you have to worry about.
Pregnancy
Research indicates that pregnant women may want to limit their intake of green tea. The same compound that makes this beverage a great cancer fighter may interfere with the way our bodies absorb folate, a B vitamin that is important to proper fetal development. EGCG, an antioxidant found in vast quantities in green tea, attacks cancer cells by bonding with an enzyme called methotrexate. This same bond inhibits the metabolism of folic acid.
Pregnant women should consult with their doctors about how much green tea is appropriate for them. Likely its consumption should be limited during the first trimester of pregnancy.
Iron deficiency
There is evidence to suggest that tea inhibits absorption of iron. For most people, this is not a problematic. For anyone with an iron deficiency, however, this means that you might need to limit your intake.
