Even Oprah swears by the benefits of this fat-burning, metabolism-boosting antioxidant. When used in combination with a healthy-eating program and fitness plan, green tea can have a great impact on cholesterol levels, heart disease, cancer, arthritis, diabetes and other medical conditions.
A recent study showed that people who drank tea for more than 10 years also had a reduction in body fat.
Green tea is loaded with an antioxidant called epigallocatechin gallete, which not only stops the growth of cancer cells but kills them as well. This property also lowers cholesterol levels and prevents the formation of blood clots, which can lead to heart attacks and stroke.
Green tea is so effective in promoting good health because of how it is made. The steaming process stops the EGCG property from being oxidized the way it is through the preparation of other teas.
Many of the weight-loss supplements on the market include green tea or green tea extract in their formula. According to a finding at the University of Geneva in Switzerland, research indicated that men who consumed a combination of caffeine and green tea extract burned more calories than those individuals burned more calories than those who took just caffeine or a placebo.
Experts also believe that green tea works to prevent blood sugar spikes following a meal by slowing the action of a digestive enzyme called amylase. In addition it's thought to increase the metabolic rate.
One of the most recent studies published in the American Journal of Clinical Nutrition revealed that the consumption of tea rich in catechins, which are found in green tea extract, lower both body fat and cholesterol levels.
Another perk is that green tea has less caffeine than your daily cup of coffee. So how much is good? The opinions change from expert to expert. While one study showed that Japanese men who drank 10 cups of green tea a day remained cancer free, another showed that women who drank five cups or more of green tea had fewer recurrences of breast cancer.
One website suggests meeting in the middle with four or five cups a day to experience the benefits of green tea. However, you can drink as much as you'd like. So far, the only known side effect from this wonder drink is insomnia, which can be attributed to the caffeine.
