Green Tea and its Metabolic Influences

Sphere: Related Content

Green tea is a tea that has found its origination from the plant called Camellia sinensis. It is one type out of the four tea types namely white, green, black, and oolong.

• White tea is called white because it is the least processed type, whereas black tea leaves are thoroughly fermented and so they get the name. Green tea leaves are known for their polyphenol content which is preserved because they are steamed not fermented.

• Polyphenol gets the credit for all the beneficial effects that are caused because of green tea, especially the catechins is considered to be the most responsible one, catechins account for more then 30% weight of the tea.

• The difference in the process in which a tea is processed accounts for the difference in the catechin content of the tea. Catechins are present in higher quantity in green tea than in black or any other type.

• The following are several polyphenolic catechins that are present in the green tea:
(1) -epicatechin (EC)
(2) -epicatechin—3—gallate (ECG)
(3) - epigallocatechin (EGC)
(4) - epigallocatechin—3—gallate (EGCG)
(5) +catechin, and
(6) + gallocatechin (GC).

• EGCG is the catechin that is found in maximum amount in the tea, it accounts for almost about 65% of catechin content in the tea.

• A single cup of green tea usually contains technically 100—200 mg of EGCG in it.
Caffeine which is present in all the teas is not at all affected by the processing methods that are applied to the tea.

Obesity
Whenever a person is having a weight that is greater then the weight that a person should have according to the general health consideration then it is called obesity.

How obesity is determined?
A term called Body Mass index is used determining whether a person is obese or is having normal body weight. Body mass index uses weight and height of a person .This index is used to correlate with the amount of fat that is present in a person’s body.

Recent studies suggest that catechins play a fantabulous role in weight loss.

Green tea promoting weight loss

Green tea is called weight loss tea. Catechins are known for influencing metabolism in several ways:

• Catechin inhibits intestinal lipases.
• It decreases absorption of fat.
• It increases excretion of fat.
• It increases the amount of uncoupling proteins in the body.
• It also increases thermogenesis.
• Decreases lipogenic enzymes.
• Suppresses appetite.

Medicinal Values of Green Tea

Sphere: Related Content
Green tea is believed to be in use as a medicine for at least 4000 years in china. It is also believed that green tea lowers the cholesterol levels by increasing the good cholesterol and decreasing the bad cholesterol. Green tea is rich in antioxidant called epigallocatechin gallate (EGCG) .It destroys cancer cells and also inhibits the growth of cancer cells. Even though the French people consume diet rich in fat, they are less prone to heart attack than the Americans. Similarly, even though 75 percent of the Japanese are smokers, they are less affected. This is because EGCG is more in green tea used by them. It acts as a protective agent against premature death from heart attack and cancer.Green tea also destroys bacteria thus preventing tooth decay. Researchers have also found that green tea even helps dieters. The leaves of green tea can also be used for cooking. The leftover leaves can be used as manure for garden plants to grow better. The ingredient present in green tea is polyphenol. It is the most effective antioxidant. It is present in higher amount in green tea than in black tea.The basic difference between green tea and other teas like oolong and black tea is that while the latter come from the leaves of camellia simens plant, green tea is processed in a different way. Green tea leaves are steamed which prevents the EGCG, a power antioxidant, from being oxidized. In contrast, black and oolong leaves are made from fermented leaves and so EGCG is converted into other compounds, which are effective in preventing and fighting various diseases.Clinical trials indicate that green tea raises metabolic rates and speeds up fat oxidation. Green tea also raises thermo genesis (the rate at which calories are burnt) and hence increases energy expenditure. Green tea also increases endurance in exercise. Drinking green tea has a whole lot of benefits like fighting against cancer, stabilizing diabetes, helping in weight loss, slowing the ageing process and helping digestion. Green tea also enhances immunity in our body. About four cups of green tea each day provides 300 to 400 mg of polyphenols, which help in antioxidant activity. These antioxidants help in slowing diseases. A research Institute in Tokyo found that drinking green tea is the best method to prevent cancer at present. All types of cancer like stomach, lungs, breast, liver, colon and rectal can be prevented by green tea.Green tea prevents cholesterol from being absorbed by the digestive tract. This in effect means that even if the fat is taken, the body does not absorb it. Green tea also helps in preventing unhealthy clotting. Rinsing the mouth with green tea after meals helps in fighting bacteria and thus prevents cavities. One cup of tea with each meal acts as a metabolic stimulant. This helps in weight loss. The caffeine in the tea burns extra calories in the body and fat is digested by polyphenols. A recent study stated that EGCG found in green tea could help to boost ones immune system thereby helping to prevent HIV.And to top it all, green tea probably is the only substance in the world with so many medicinal values and without a single side effect!sVisit http://www.healthopts.com for useful weight management tips and choosing successful weight loss Plans.

Amazing Green Tea Health Benefits.

Sphere: Related Content
Green tea has been used as a medicine in China for at
least 4,000 years. It's benefits to human health have been
widely known and talked about ever since it was first
discovered. Legend says that green tea was discovered in
2737BC when the emperor Shen Nung was boiling some water
for drinking and some leaves from a tree nearby blew into
it. The wonderful smell induced the emporer to try this new
drink and he found the taste heavenly and very refreshing.
Green tea was later brought from China to Japan by Buddhist
monks.

Green tea, like black tea is made from the leaves of the
plant Camellia sinensis. The difference between the three
main types of tea is the way that they are produced. Green
tea is unfermented tea meaning that the leaves used for
green tea are steamed soon after been plucked in order to
prevent the oxidation of the leaves. In this way the leaves
remain green and the active substances within the leaves
retain their qualities. Black teas on the other hand are
made from fermented leaves and as a result have less
nutritional and enzyme content as the green tea. Thus green
and black teas have different chemical properties.

Modern science has in recent times been able to
demonstrate that green tea is beneficial to one's health
and this is mainly due to the fact that tea contains high
levels of antioxidants called polyphenols or flavonoids.
The antioxidant activity of tea has been compared to that
of fruit and vegetables in a number of studies. One study
concluded that consuming three cups of tea a day produced a
similar amount of antioxidants as eating six apples.
Antioxidants help your body fight against free radicals
which cause damage to cells and tisuues in your body.

While all tea is healthy to drink, it is green tea that
contains the highest level of flavonoids. Recent medical
studies suggest green tea to be beneficial in many areas
including the following:
-Digestive and respiratory health.
-Lowers cholesterol levels
-Boosts your immune system
-Reduces high blood pressure
-Arthritis - anti-inflammatory effect.
-Oral hygiene - due to antibacterial properties.
-Skin conditions such as acne
-Lowers blood sugar

Another potential benefit is in the area of weight loss.
Research recently published in the American Journal of
Clinical Nutrition suggests that an extract from green tea
may speed up fat oxidation. Ten healthy men in their 20's
were studied for 6 weeks and it was discovered that those
men who were given a green tea extract used more calories
in a day than those who did not. This appears to be due to
green tea having thermogenic properties thus causing the
body to burn fat faster than usual. One word of caution
though - if you need to lose weight - and all you do is
drink green tea without making any other lifestyle changes
then do not expect an instant miracle! However green tea
combined with a healthy balanced diet and regular exercise
provides will help you in your weight loss program. Lorraine Bevere is the webmaster of FOG Tea, Inc. which isa premier source of information about tea. For questions orcomments about this article, please visit:http://fogtea.com
