Green Tea Diet
Obesity continues to be one of the major health problems in society today. More than half of the American population is overweight or obese. As a result, diet and weight loss plans have become increasingly fashionable. But not all diet plans work. And not all of them are naturally risk-free. A safer alternative for people wanting to lose weight are green tea diets.
About Green Tea
For thousands of years, this tea has been highly valued by the Chinese as both a herbal and medicinal drink. It was believed green tea was first discovered by the Chinese Emperor Shen Nung who was boiling water when the leaves of a nearby tree fell into his pot. The result was the first ever pot of this tea.
Like all three of the major Asian teas, green tea comes from the plant called Carmellia sinensis. Much of the health benefit of a green tea diet is due to the steaming method of making it. As opposed to black and oolong tea which undergoe full oxidization, green tea is only gently steamed, preserving the natural antioxidants in its original form.
The Health Benefits of Green Tea Diet
There are extensive health benefits implicated with having a green tea diet. One of these benefits is cancer prevention. Certain substances present in green tea are said to help in destroying cancer cells without harming any neighboring tissues. This substance in a green tea diet is called epigallocatechin gallate or EGCG.
EGCG is also helpful in increasing the 24-hour energy expenditure of the body. A study on green tea diets conducted by American and Swiss scientists in the University of Geneva showed an additional increase of four percent in the body's natural energy expenditure. People who were on this diet were more likely to use up more fats than those not on this diet.
Also, this diet is said to greatly help lower cholesterol levels in people. The study on green tea diets was conducted in China using 240 people with high cholesterol levels as subjects. These people were placed on a diet of one capsule (equivalent to seven cups of the tea) or were given one placebo every day. After twelve weeks, those who were on this diet dropped sixteen percent in their cholesterol levels.
A diet including green tea can also be a potential cure to obesity. The catechin polyphenols present in the tea can delay the reaction of gastric and pancreatic lipases in the body. These enzymes are responsible for converting calories in the body into fats. By delaying these enzymes, the tea stops fat from being stored and prevent obesity in people.
Green tea contains a substantial amount of caffeine making it a mild appetite-suppressant. However, caffeine content in the tea is not as high as those found in other caffeine-based beverages, like coffee. Caffeine may be harmful for the body since an excess of it can cause heart palpitations, hypertension, and insomnia. Because this diet contains only very low levels of caffeine, there is no danger of experiencing these side-effects.
