7 Types of Tea

Full Article: Health Benefits

Unlike coffee, where moderation is key, lots of tea means lots of health benefits. And nowadays, even your run-of-the-mill grocery store stocks a huge selection of teas in every flavor and color.

Tea is the most widely consumed beverage in the world, other than water, according to the Tea Association of the USA. Even in the United States, which is typically thought of as a coffee-drinking nation, tea is a mainstay in close to 80 percent of households.

Interestingly, ALL tea (except herbal tea) comes from the same plant, a warm-weather evergreen called Camellia sinensis. (Herbal teas are made from leaves, roots, bark, seeds or flowers of other plants, and technically are "infusions" or "tisanes," not "teas.") It's the way the plant is processed that makes the varieties take on their characteristic color and taste. Green tea, for instance, is not exposed to any oxygen, and its leaves are simply steamed, rolled and dried. Black tea, on the other had, is exposed to oxygen, or oxidized, for two to four hours.

1. Black Tea
Of all the tea Americans drank in 2007, 82 percent of it was black tea. Studies have shown that regularly drinking three or more cups of black tea a day can reduce your risk of heart disease and stroke. A study in the European Heart Journal also found that drinking black tea improves the ability of arteries to relax and expand to keep blood pressure healthy (but adding milk to the tea blocked this impact!).

2. Green tea
Accounted for 17 percent of Americans' tea consumption in 2007. It is one of the most talked about "healthy" teas, as it's a rich source of catechin polyphenols, namely epigallocatechin gallate (EGCG), which is a potent antioxidant. Here is just a short list of some of the conditions green tea is supposed to help:
- Cancer
- Rheumatoid arthritis
- High cholesterol levels
- Heart disease
- Infection
- Impaired immune function
- Obesity, overweight
- High blood sugar levels

3. Oolong Tea
Oolong tea comes from leaves that are withered, rolled, semi-fermented and fired, resulting in a rich flavor and aroma. Oolong tea is especially rich in polyphenols and studies have found that it can help to reduce obesity, prevent tooth decay and improve atopic dermatitis. Research has also suggested that drinking oolong tea after a high-cholesterol meal may reduce the uptake of fats into your bloodstream.

4. White Tea
White tea is the least processed form of tea; the leaves and buds are only steamed and then dried. It is similar in health benefits to green tea, but in some cases may be even healthier. For instance, a study by the Linus-Pauling Institute found that white tea was more effective than green tea in inhibiting mutagenicity, an early step in the process leading to cancer. White tea also contained certain polyphenols in levels higher than in green tea brewed under the same conditions.

5. Matcha Tea
Matcha is a high-quality green tea in which the leaves are ground into a powder. The tea particles are therefore added right to the water, rather than being steeped and strained like typical teas, resulting in a strong, somewhat bitter flavor. Matcha is the only type of tea in which the whole leaf is consumed, so very high-quality leaves are used. It is said to be one of the healthiest green teas out there, known for helping to prevent cancer and heart disease and slow the aging process.

6. Pu-erh Tea
Pu-erh tea is processed, fermented, formed into bricks or "cakes," and then aged (in fact, it's the only type of tea that is aged). Named for the town in Southwestern China where it is grown, pu-erh tea has been enjoyed by the Chinese for decades and is said to lower cholesterol, aid digestion and cure hangovers. This tea is known for its strong, earthy taste, and can be quite expensive the older it gets.

7. Red Tea
Red tea, also known as rooibos, is an herbal tisane grown only in South Africa. Like green tea, rooibos is rich in polyphenols and flavonoids that may help to boost your immune system and protect you from free radical damage. This naturally caffeine-free infusion is also rich in healthy minerals such as iron, potassium and copper.
