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 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.
