Green Tea Diet
Obesity has become one of the major health issues in our society today.
More than half of the American population is overweight or obese. As a
result, diet and weight loss plans have become increasingly popular.
But not all diet plans work. And not all of them are necessarily
risk-free. A safer alternative for people wanting to lose weight are
green tea diets.
About Green Tea
For thousands of years, green tea diet has been highly valued by the
Chinese as an herbal and medicinal drink. It was believed that green
tea diet 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 green tea.
Like all three of the major Asian teas in the market, green tea comes
from the plant called Carmellia sinensis. Much of the health benefits
of green tea diets owe to the steaming method of making it. As opposed
to black and oolong tea which undergoes full oxidization, green tea
diet is only gently steamed, preserving the natural antioxidants in its
original form.
The Health Benefits of Green Tea Diet
There are many health benefits associated with having a green tea diet.
One of these green tea diet benefits is preventing cancer. Certain
substances present in green tea diets are said to help in destroying
cancer cells without harming any neighboring tissues. This substance in
green tea diets is called epigallocatechin gallate or EGCG.
EGCG in green tea diets 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 a green tea diet were more likely to
use up more fats than those not on a green tea diet.
Also, green tea diets are said to greatly help in lowering down
cholesterol levels in humans. 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 green tea diet of one capsule
(equivalent to seven cups of green tea) or were given one placebo every
day. After twelve weeks, those who were on a green tea diet dropped
sixteen percent in their cholesterol levels.
Green tea diets can also be a potential cure to obesity. The catechin
polyphenols present in green tea diets 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, green tea diets can therefore stop fat from being stored
and prevent obesity in people.
Green tea diets contain substantial amount of caffeine that make it a
mild appetite-suppressant. However, caffeine content in green tea diets
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 green tea
diets contain only very low levels of caffeine, there is no danger of
experiencing these side-effects.
