Discover the Connection Between Green Tea and Health

By:   |   Jul 08, 2018   |   Views: 10   |   Comments: 0

Are you frustrated with listening to all the claims about green tea and health? The positives far outweigh the negatives if you are careful. Let's start with the negatives.

Dr Chung Yang of Rutgers, the State University of New Jersey stated "People shouldn't be too alarmed by this, but those taking supplements may experience problems," says the lead author of the study. "Up to 10 small cups of green tea a day is fine. Problems are likely in people who take supplements, which can contain up to 50 times as much polyphenols as a single cup of tea."

A large amount in a supplement would be considered to be 750-1000 mg of extract per day or higher depending on body weight and the quality of the supplement. Over dose symptoms can include insomnia, headaches, digestive problems and higher blood pressure. Liver and kidney damage has also been associated with too much consumption.

Why do people drink it?

The tea polyphenols previously mentioned by Dr Yang are collectively called catechins of which the two most potent are epigallocatechin gallate [EGCG] and epicatechin gallate [ECG].

A laboratory study performed by the University of Mississippi found that high doses of extract containing ECG may increase cancerous tumor growth. Low doses have been found to suppress new tumor growth with no observed side effects.

Other studies have shown that EGCG in moderate amounts lowers LDL ["bad"] cholesterol levels and blood pressure, reduces the risk of stroke and improves your hearts health in general. This is important since the World Health Organization rates cardiovascular disease as the worlds number one cause of death.

Studies in England and China have revealed that women drinking only one cup per day had higher bone mineral density than non tea drinkers. This along with adequate amounts of calcium, vitamins D and K and exercise can lower the risk of osteoporosis.

There is some information that green tea can speed up your metabolism slightly which could cause some weight loss. The claims here are based more on hope than on evidence but you will not gain weight by drinking it! However, try not drink it with meals as it can cause digestive problems for people with sensitive stomachs.

Make no mistake about it. A preponderance of the evidence points to green tea having numerous benefits and very few side effects, if it is taken in small to moderate doses by the cup or by supplement. As with all nutrients it works best when balanced with a wide variety of vitamins, minerals and nutrients.
