All about Teas

Tea is the most popular beverage in the world after water. It’s a simple preparation of pouring hot water over cured leaves of the Camellia sinensis plant. The first recording of tea described it as a medicinal beverage in China in the 3rd century AD. Merchants helped its popularity to spread quickly across continents. In the early 19th century, Great Britain popularized the concept of afternoon tea, a break from one’s routine in which tea is served alongside sandwiches and baked goods such as scones. The flavor of tea varies by where the tea leaves are harvested and how they are grown and processed. Black tea is the most popular worldwide, followed by Green, Oolong and White tea. Herbal teas are not made from the Camellia plant but from dried herbs, spices, flowers, fruit, seeds, roots, or leaves of other plants; they do not typically contain caffeine as do traditional teas.Source Of · Caffeine (traditional teas, not herbal)  · Polyphenols

Most traditional teas do not contain a significant amount of nutrients, but are rich in polyphenols. These are plant chemicals that give teas their distinct flavor and aroma and may have health-promoting properties. Spotlight on Tea and Antioxidants

Polyphenols, or flavonoids, are likely a key component to what makes tea a healthful drink. These chemical compounds act as antioxidants, which control the damaging effects of free radicals in the body. Free radicals can alter DNA by stealing its electrons, and this mutated DNA can increase LDL cholesterol or alter cell membrane traffic—both harmful to our health. Though Green tea is often believed to be richer in polyphenols than Black or Oolong (Red) teas, studies show that—with the exception of decaffeinated tea—all plain teas have about the same levels of these chemicals, albeit in different proportions. Green tea is richest in epigallocatechin-3 gallate whereas black tea is richest in theaflavins; research has shown that both can exert health benefits. Herbal teas contain polyphenols as well but will vary highly depending on its plant origin.

Indeed, one reason for conflicting results in observational studies may be the wide variations in tea types with varying flavonoid content. Where the tea leaves are grown, the specific blend of tea leaves, type of processing and addition of ingredients such as milk, honey, and lemon can alter specific flavonoid content. How accurately people report their tea intake (e.g., type, amount, brew strength) and their overall diet (e.g., do they eat other foods rich in flavonoids?) are other factors that need to be clarified as they can affect study results. For example:

· Some research suggests that the protein and possibly the fat in milk may reduce the antioxidant capacity of tea. Flavonoids are known to “deactivate” when binding to proteins so this theory makes scientific sense. [6] 

· One study that analyzed the effects of adding skimmed, semi-skimmed, and whole milk to tea concluded that skimmed milk significantly reduced the antioxidant capacity of tea. Higher-fat milks also reduced the antioxidant capacity of tea, but to a lesser degree. All said, in practice it’s important to keep in mind that tea—even tea with a splash of milk—can be a healthful drink.

Observational research has found that tea consumption of 2-3 cups daily is associated with a reduced risk of premature death, heart disease, stroke, and type 2 diabetes. However, there may be an increased risk of esophageal and stomach cancers from drinking tea that is too hot (more than 131-140° F [55-60° C]).

Store

There are five elements to avoid to keep tea as fresh as possible: light, heat, moisture, odor, and air. Loose-leaf teas should be stored in an airtight container. Tea bags should be stored in their original container or placed in a sealed plastic bin. Place all teas in a dark cupboard at a consistent room temperature. Tea tends to absorb odors from food and even other strongly scented teas, so keep them separate. Freezing and refrigerating is not recommended as the moisture introduced can degrade the tea.

If unopened, tea will last about one year beyond the “best by” date. After opening, packaged and loose-leaf teas last about one year. However, some Black and Oolong teas can last up to two years, and more delicate teas may last only 6-9 months. The flavor is your best guide to determining how long to keep a tea in your cupboard.

Make

Avoid purchasing expensive bottled teas or teas from shops that contain added sweeteners. To enjoy the maximum benefits of drinking tea, consider brewing your own at home. You can serve it hot, or make a pitcher of home-brewed iced tea during warmer months.

Black and Oolong teas are generally steeped in hot or boiling water (about 210º F) and brewed for about 4-5 minutes. Green tea is steeped at a slightly lower temperature 180º F from 4-15 minutes. The longer tea steeps, the stronger the flavor with bitter notes.

Additives of sugar, cream, or milk can reduce the polyphenol content of tea. For the greatest health benefits, try serving tea plain or without too many additives. A dash of vanilla or cinnamon can mimic sweetness. Some fruit-flavored herbal teas taste naturally sweet to the palate without added sweeteners.

· What western coffeehouses commonly refer to as “chai” is more accurately called “Masala chai” or “spiced tea” (“chai” is simply the Hindi word for “tea”). The recipe for this beverage has varied widely across time and place, but today is often made from Black tea mixed with spices like cinnamon, cardamom, cloves, ginger, and peppercorns, and served with milk and sweetener.

· Japan has a rich tea culture, best known for the ceremonial preparation and drinking of Green tea. A traditional Japanese tea ceremony, also called “the way of tea” (茶道 [sadō or chadō] or 茶の湯 [chanoyu]) can take up to multiple hours!

· Yerba mate, or mate, is a popular herbal tea in South America made from the dried leaves of the Llex Paraguariensis tree. It shares traits with coffee in that they both contain the antioxidant polyphenol chlorogenic acid and similar amounts of caffeine. There has been concern that certain processing methods of mate, such as drying the leaves with smoke, may introduce polycyclic aromatic hydrocarbons (the carcinogenic substances also found in grilled or smoked meats). Some research links drinking large amounts of mate over time with increased risk of certain cancers, including head and neck, stomach, bladder, and lung, but it is not clear if the risk is due to drinking it very hot or the presence of polycyclic aromatic hydrocarbons. Therefore, mate fans may choose to drink it at moderate temperatures or to purchase brands that process it by air-drying rather than smoking.Tea is the most popular beverage in the world after water.
