Tea

• Depending on the manufacturing process, teas are classified into– Green tea – Black tea– Oolong tea

Green tea

• Green tea contains polyphenols, which constitute 30 % by dry weight and include– flavanols, – flavandiols – flavonoids– phenolic acidsThe main flavonoids present in

green tea includecatechins (flavan-3-ols).

Green Tea Extracts

• Liquid form• Powder form

• Extracts contain– Polyphenols (45-90%)– Caffeine (0.4 -10 %)

Green Tea Extract

One cup of green tea generally contains 100—200 mg of polyphenols

Taking one Green tea extract capsule is like drinking 4-5 cups of green tea! They are the concentrated source of goodness of green tea!

Green tea extract capsules are easy and convenient form to take compared to green tea

Polyphenols or Catechins

The four major catechins and the approximate content of each of the total amount of catechins are:

• epigallocatechin-3-gallate (EGCG), (59%)

• epigallocatechin (EGC) (19%)• epicatechin-3-gallate (ECG) (13.6%)• epicatechin (EC) (6.4%)

Green Tea Polyphenols

Antioxidants• Destroying the free radicals that

damage cells.• Promoting the growth of healthy

cells.• Protecting cells against premature,

abnormal ageing.• Help fight age-related macular

degeneration.• Provide excellent support for the

body’s immune system

Conditions in which Antioxidants can reduce the risk

• Damage to cells by free radicals may cause cancer

• Aging of the cells itself is a potential factor for certain conditions

• Age-related macular degeneration is when vision is affected because of damage to retina.

• Immune system weakens due to several reasons and can cause recurrent infections which affect quality of life

Antioxidant Activity

Health Benefits of Green Tea

• Green tea extract (EGCG) has been linked to– Inhibition of cancer development– Helps in Weight management– Improves heart health

• Reduced LDL oxidation

– Aids in management of diabetes– Reduced number of cavities– Skin protection– Miscellaneous

Anticarcinogenic• Studies clearly demonstrated the

benefits of green tea and EGCG against many types of cancers

• Tea catechins act as powerful inhibitors of cancer growth in several ways– Remove harmful chemicals before cell

injuries occur– Reduce the incidence and size of tumors– Inhibit the growth of tumor cells– Increase in tumor cell apoptosis

(programmed cell death) – Decrease in cell proliferation

Anti-Hypertensive

• There are reports that habitual moderate strength green tea consumption over long period of time reduces the risk of developing hypertension

Heart Health

• Decreased Cardiovascular Disease Risk

• Epidemiological studies suggest that green tea consumption is associated with a reduced cardiovascular disease risk.

• The oxidation of LDL-cholesterol, associated with a risk for atherosclerosis and heart disease, is inhibited by green tea due to EC and EGCG antioxidant activity.

(MacKay and Blumberg 2002, Ishikawa et al 1997)

Dental Health

Tea polyphenols are anticarious in three ways:

• They inhibit the plaque forming enzyme,

• Preventing bacterial growth– they suppress the growth of S. mutans,

and

• Solidify the enamel – Increases the resistance of tooth enamel

to acid induced erosion– Displays anti-inflammatory properties by

reducing gum disease (gingivitis)

Skin protection

• Green Tea Polyphenols are photo-protective in nature – Can be used as pharmacological agents

for the prevention of solar UVB light-induced skin disorders

– Photo-aging• Decelerates skin aging and gives the skin a

shine

– Can heal acne and small cuts– Has the ability to calm the rash, skin

irritations and redness– Protective against skin cancers

Katiyar et al 2000

Weight Management• Green tea has thermogenic

properties• Promotes fat oxidation that can be

attributed to caffeine and catechins• Reduced fat absorption• Catechins influence intestinal and

cell metabolism in several ways:– Inhibiting intestinal lipases– Increasing fat excretion– Increasing uncoupling proteins– Decreasing lipogenic enzymes– Suppressing appetite

Diabetes Management

• Improves glucose tolerance– Epidemiological observations and

laboratory studies have shown that green tea has a positive effect on glucose tolerance and insulin sensitivity.

• Increases insulin sensitivity.– EGCG is the most active catechin in

increasing insulin sensitivity and glucose uptake.

Other Benefits

• Anti Bacterial - action against harmful food borne pathogenic bacteria– Increases antibiotic effectiveness – Effective in preventing HIV infection at

the initial step in the HIV-1 infection process

• Anti Viral – Works well for those having cold

• Bone density - Positive effect on proliferation and activity of bone cells

Why Green Tea Extract?

• One capsule of green tea extract is it is equivalent to consuming about 4-5 cups of green tea.

• Convenient and easy to take. – One can take it while

travelling etc unlike green tea which needs to be prepared.

Summary

• The beneficial effects of green tea are attributed to the polyphenols, particularly the catechins, which make up 30% of the dry weight of green tea leaves.

• These catechins are present in higher quantities in green tea than in black or oolong tea, because of the differences in the processing of tea leaves.

• Green tea polyphenols are effective in preventing many chronic diseases such as cancer, diabetes, and heart disease and they are help to maintain healthy weight.
