Green tea has been a popular staple for those looking to have a healthier diet for many years. New evidence has demonstrated the use of green tea extracts, which are purified compounds taken directly from the leaves of the tea, are particularly effective for those seeking weight control and also help to regulate glucose production in diabetics. Part of the goal in researching this has been to test the potential of the simple treatment. Keimyung University School of Medicine recently conducted a study looking for just this. They found several interesting compounds that are naturally in green tea which show great promise in this area.
There are several active compounds found in green tea, several of which have been demonstrated to inhibit lipid uptake and glucose levels in the intestines. The major compound is a certain type of flavonoid known as gallated catechins. The amount of these gallated catechins that are required to reduce glucose concentrations in the blood her and she achieved with only a single daily serving of green tea. Yet the level of green tea necessary to decrease lipid uptake in the intestine is slightly higher, having been shown to be too high to feasibly get from green tea directly. These gallated catechins actually were shown to increase insulin resistance, which is a negative consequence for diabetic patients.
Researchers in the study found that green tea extract on factors such as bodyweight or glucose tolerance in mice or diabetic mice were noteworthy. Through the use of a non-toxic resin called polyethylene glycol, the mice who were fed a high-fat diet and significantly improved results from the normal extract. This was thought to have prevented the uptake of gallated catechins at a level which would be harmful, which prevented problems in controlling lipid absorption. They then compared the results to the results often seen from two other drugs which are typically prescribed to people trying to lose weight, or to diabetic patients.
What This Says About the Use of Green Tea for Dieting
Green tea is known for providing energy and also antioxidants into the body, which helps keep a person healthy in ways ranging from reduction in cancer risk to helping them to shed pounds. Yet, the results the study suggest that there are other benefits which we do not know about previously. If a person is taking green tea extract along with polyethylene glycol, they saw significant drop in overall body mass, insulin resistance and improved tolerance for glucose, regardless of whether they had a high fat diet or a more diabetic diet. The polyethylene glycol contained in the extract was found to have an impact on the amount of time the gallated catechins remained in the body, which as a result, limited the glucose absorption therein.
The effect of green tea extract was found to be of a measurable value just by drinking it daily, yet the results were significantly improved if taken as an extract instead. In addition to this information, it was also found that the effects of green tea extract the body are comparable to the same results found if a person was taking two different drugs that are typically prescribed for non-insulin dependent diabetics.
It’s our conclusion from this information that the use of “green tea extract for dietary purposes and polyethylene glycol help to alleviate weight gain and insulin resistance in overweight and diabetic mice.” What this means is that green tea extracts have some preventative and therapeutic properties which can help with obesity-related illnesses as well as the risk of diabetes. The side effects are still being studied but the use of polyethylene glycol significantly improves the extracts benefits and the behavior in patients.
