Different processing methods are used to produce the hundreds of varieties of tea: Black teas, which are most common in Europe3, are produced when tea leaves are fermented broken down by the enzymes in the tea leaves, in a temperature controlled room and then dried.
Tea: Health and hydration
These processes release the specific polyphenols , which produce the distinctive colour and flavour. Oolong tea is somewhere between green and black tea in terms of fermentation and taste — its leaves are only partially oxidised. Black and green and oolong teas contain different types of polyphenols, but the total polyphenol content is similar.
However, more research is needed to understand to what degree and through which mechanisms this affects the bioavailability of the different polyphenols. Is tea good for health? There is much more research published on green tea than black and other teas. Some studies even suggest that green tea may increase the risk of stomach cancer. More studies are underway to see whether green tea helps reduce the risk of stomach cancer. If green tea proves to help prevent colon cancer, it would also help those with IBD because they are at higher risk for colon cancer.
Diabetes Green tea has been used traditionally to control blood sugar levels.
Animal studies suggest that green tea may help prevent the development of type 1 diabetes and slow the progression once it has developed. In people with type 1 diabetes, their bodies make little or no insulin, which helps convert glucose or sugar into energy.
Green tea may help regulate glucose in the body. Research also suggests that regular consumption of green tea may help manage type 2 diabetes.
Liver disease Population-based studies have shown that men who drink more than 10 cups of green tea per day are less likely to develop liver problems. Green tea also seems to protect the liver from the damaging effects of toxic substances such as alcohol. Animal studies have shown that green tea helps protect against liver tumors in mice. Results from several animal and human studies suggest that plant chemicals in green tea called catechins, may help treat viral hepatitis, an inflammation of the liver.
In these studies, catechin was used by itself in very high amounts. It is not clear whether green tea, which has a lower concentration of catechins, would have the same benefits. It is important to note that 10 cups of green tea a day could cause problems due to high levels of caffeine.
Ask your doctor about the best way to include green tea in your treatment. Weight loss Clinical studies suggest that green tea extract may boost metabolism and help burn fat. One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.
However, other studies show no benefit. Other uses Preliminary studies suggest that drinking green tea can help prevent dental cavities. More research is needed. Green tea may also be useful in inflammatory diseases, such as arthritis. Research suggests that green tea may help arthritis by reducing inflammation and slowing the breakdown of cartilage. Chemicals in green tea may help treat genital warts, treat dermatologic conditions, and prevent symptoms of colds and flu.
Green tea may play a role in preventing Parkinson disease, cognitive decline, and osteoporosis. Studies also show that drinking green tea is associated with reduced risk of dying from any cause. Plant Description Green, black, and oolong tea are all derived from the leaves of the Camellia sinensis plant.
Originally cultivated in East Asia, this plant grows as large as a shrub or tree. People in Asian countries more commonly consume green and oolong tea while black tea is most popular in the United States.
Green tea is prepared from unfermented leaves, the leaves of oolong tea are partially fermented, and black tea is fully fermented. The more the leaves are fermented, the lower the polyphenol content and the higher the caffeine content. Green tea has the highest polyphenol content while black tea has roughly 2 to 3 times the caffeine content of green tea. What's It Made Of? Researchers think the health properties of green tea are mostly due to polyphenols, chemicals with potent antioxidant potential.
In fact, the antioxidant effects of polyphenols seem to be greater than vitamin C. The polyphenols in green tea also give it a somewhat bitter flavor. Polyphenols contained in teas are classified as catechins. Green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and apigallocatechin gallate also known as EGCG. EGCG is the most studied polyphenol component in green tea and the most active. Green tea also contains alkaloids including caffeine, theobromine, and theophylline.
They provide green tea's stimulant effects.

L-theanine, an amino acid compound found in green tea, has been studied for its calming effects on the nervous system. Differences among the five types of tea result from the various degrees of processing and the level of oxidization. Black tea is fully oxidized and oolong teas are partially oxidized. After withering and rolling, the tea leaves undergo natural chemical reactions resulting in taste and color changes which develop the teas distinguishing characteristics.
Oolong tea is midway between black and green teas in strength and color. Dark teas are fermented after manufacture. History: Tea is nearly 5, years old. According to Chinese tea scholars, the Emperor, as a botanical explorer, accidentally poisoned himself some 85 times, each time being cured by this wonderful brew.
Tea played a dramatic part in the establishment of the United States of America. In the British Government passed the Revenue Act one of the Townshend Acts putting a tax on tea, as well as British china, glass, lead, paint and paper, imported to America.
In , after much protest, the Townshend Acts were repealed and all taxes removed with the exception of the tax on tea. In , the passage of the Tea Act, granting a monopoly to the British East India Company on all tea sales to the American Colonies, effectively raised tea prices. On the night of December 16, , men dressed as Native Americans Mohawk Indians boarded British ships in Boston Harbor and threw more than chests of tea into the sea.
While not the only instance of tea being thrown overboard or otherwise destroyed in protest throughout the colonies, this most famous Boston Tea Party was said to be a principle act leading to the Revolutionary War. Anna, Duchess of Bedford, is credited with creating Afternoon Tea in , when she began taking tea with a light snack around p. Recently, the U.
Environmental Qualities: Tea is an all-natural and environmentally sound product from a renewable source. Tea supports sustainability in three ways: ecological, social and economic. Hundreds of thousands of workers are involved with the growing, production and manufacturing of the tea that you consume every day.
The tea plant is naturally resistant to most insects; oxidation of the tea leaf is a natural process; and, many tea packers use recycled paper for packaging. Health Qualities: Tea is a refreshing beverage that contains no sodium, fat, carbonation, or sugar. It is virtually calorie-free.
Tea helps maintain proper fluid balance and may contribute to overall good health. Tea contains flavonoids, naturally occurring compounds that are believed to have antioxidant properties.
Tea flavonoids often provide bioactive compounds that help to neutralize free radicals, which scientists believe, over time, damage elements in the body, such as genetic material and lipids, and contribute to chronic disease. Recent research has explored the potential health attributes of tea through studies in humans, animal models and through in vitro laboratory research. For the most part, studies conducted on green and black tea, which are both from the Camellia sinensis plant, have yielded similar results.
About the Publisher
Recent research suggests that tea and tea flavonoids may play important roles in various areas of health and may operate through several different mechanisms still being explored. Research continues, and the list of key areas of research are as follows: Heart Health: Human population studies have found that people who regularly consume three or more cups of black tea per day have a reduced risk of heart disease and stroke.
Using survey data from Multi-Ethnic Study of Atherosclerosis, a investigation found that those who drank more than one cup of tea per day had a lower incidence of cardiovascular events and a slower progression of coronary artery calcification. After 5-year follow-up there were significantly lower levels of total cholesterol, LDL, and mean platelet volume and increased HDL and uric acid levels among green tea consumers.
One study found that women who consumed the equivalent of 2.
Caffeine and Sleep
Men who drank more than 1. A recent review paper of in vitro, in vivo and human studies highlights the various mechanisms by which consumption of Green tea and topical application may have preventative effect against skin cancer. EGCG, along with other polyphenols, act by increasing DNA repair mechanisms, reducing UVB mediated inflammation and oxidative stress and down regulating pathways involved in carcinogenesis. Green tea polyphenols EGCG may also suppress the action of p53, which is involved in tumor suppression.
Studies have shown that the topical application, as well as dietary supplementation of Green or white tea extracts may protect the skin from UV damage by increasing DNA repair. Last, epigenetic modification is caused by UVB exposure, research shows that EGCG may reduce tumor incidence and decrease tumor multiplicity and size. Notably, the clinical trials reviewed indicated that green tea may specifically slow prostate cancer progression.
This review illustrated that EGCG may modify several critical processes in the cell cycle as well as induce cervical cancer cell apoptosis and inhibit telomerase activity.
This human-based data is supported by data from animal models. EGCG was also found to increase levels of intracellular antioxidants, which inhibited reactive oxygen species and had a protective effect on neuronal cells.
The benefit of tea catechins may stem from their antioxidant activity, interaction with cell signaling pathways and anti-inflammatory effects. A recent review indicates that tea consumption may be related to reduction in anxiety, benefits in memory and attention and brain function. This suggests Black tea may have a positive effect on long-term diabetes management. Rats given the treatment also had AMPK activation which resulted in greater insulin sensitivity, reduced de novo lipogenesis and decreased liver fat content.
The results of another meta-analysis suggest the increase in caloric expenditure is equal to about calories over a hour period. The weight loss benefits of tea vary based on many factors, but studies have found benefits with the equivalent of as little as 2.
Across the studies there was a significant increase in BMD for tea drinkers verses non-drinkers. A cup of Black Tea, for example, contains about 40 milligrams of caffeine.
Cost Per Serving: Prepared at home, tea costs about three cents per serving, cup or glass. Tea continues to remain one of the most economical beverages available, even the most expensive teas are less than 10 cents per serving.
Tea: Tea is a refreshing beverage that tastes great and contains no sugar, sodium, or fat. In addition to being naturally calorie-free, it contributes to total water intake promoting hydration.
Key Tea Terms: Antioxidant: A substance that helps prevent or delay oxidative damage caused by reactive oxygen and or reactive nitrogen species.
Oxidative damage to the body, cells and tissues may contribute to diseases like cancer and heart disease. Phytochemicals: Naturally occurring plant compounds.
Is tea good for health?
Many phytochemicals are thought to play a role in decreasing the risk of cancer and heart disease and may boost the immune system. Some phytochemicals such as tea flavonoids are also antioxidants. Flavonoids: A class of polyphenolic phytochemicals found in tea that are effective antioxidants. Tea flavonoids and related bio-active compounds in tea may play important roles in various areas of heath and may operate through a number of different mechanisms still being explored.
Flavonols: A group of flavonoids found in tea and many fruits and vegetables that are antioxidants and are thought to contribute to some of the potential health benefits in these plant foods.
They include rutin, quercetin and kaempferol. EGCG is a strong antioxidant and has been shown to reduce formation of lung, esophageal and skin tumors in animal models of human cancer.
Theanine: An amino acid commonly found in tea that can cross the blood-brain barrier, therefore has psychoactive properties.Your last name: In one study, women who drank 5 or more cups of green tea per day had a lower risk of colorectal cancer compared to non-tea-drinkers. Specifically, the prominent green tea catechin, EGCG, and black tea polyphenols, theaflavins and thearubigins, are thought to contribute to the protective effect of drinking tea by promoting antioxidant activity and endothelium-dependent vasodilation It was especially true in premenopausal women in the early stages of breast cancer.
