Health Benefits Of Tea

Health benefits of drinking tea 

The question,  Why you enjoy tea might have never popped up in your mind,  while sipping it in front of a fire place  in a cold winter morning.How drinking tea is good for you

Tea has long been an institution, with millions of cups supped each day, making it an unlikely staple of modern-day living. But now it seems that green tea and even the humble brew could also offer more than a simple caffeine fix with tremendous health benefits to be found in tea.
A number of scientific researchers have been investigating the possible health benefits contained within tea. And now it appears there’s a growing body of evidence to suggest that drinking tea could actually ward off some very serious conditions, including cancer, obesity and dehydration. Studies have suggested that drinking three or more cups of tea a day could actually be better for you than drinking the same amount of water, with the antioxidants contained within tea boosting the body’s health, at the same time as rehydrating it.

The main health benefits of tea drinking

Here are some of the key health benefits that scientists reckon tea drinking can have on the body:
  • Tea reduces the risk of heart disease — Tea can potentially improve the blood flow around the body, by widening key arteries and reducing the risk of clots. Tea also contains antioxidants calledflavonoids, which may slow down the onset and risk of heart disease.
  • Tea hydrates the body — Although water is the prime fluid for rehydrating the body after exercise or a long day in the office, some scientists believe that drinking tea could be equally useful. Although high in caffeine, tea is still great for hydration as it provides a rich and flavoursome source of water.
  • Tea prevents tooth decay — Believe it or not, a regular supply of tea can really strengthen your teeth and lower the risk of tooth decay. Tea is a great source of fluoride, which can bolster tooth enamel. The antioxidants contained within a cuppa have also been known to fight against bacteria and gum disease. So get slurping!
  • Slimming through tea drinking? — Some scientific studies have suggested that regular tea drinking can help to keep body fat down by speeding up the burning of calories. If nothing else, it’s less fattening than sipping on a soft drink.
  • Boosting memory power with tea — Many scientists believe that certain types of tea, such as green tea, can strengthen memory cells in the brain, and offer protection from the development of dementia and even Alzheimer’s disease. No wonder old people drink so much tea!
  • Beating cancer through the power of tea — Some high-profile studies have recently suggested that tea drinking could seriously help your chances of avoiding cancer. Although research is still developing in this area, reports indicate that prostate, mouth and breast cancer cases are much lower amongst those who regularly drink five or more cups of tea a day.   
  • Types of healthy tea
    With so many potential health benefits, there’s never been a better time to put the kettle on. But which form of tea is the most beneficial to you? Is that large cup of creamy, sugary black tea really going to help your body feel better? Let’s find out…
      
    Health Benefits of Green Tea

    Following new scientific developments, research into the health effects of green tea has advanced significantly. Studies have shown that green tea is made of several main components that contribute to its character: catechins (texture), caffeine (bitterness), and theanine (flavor), as well as various vitamins and minerals. Present in large quantities of green tea, catechins (including EGCG) are a type of polyphenol that is also a component of red wine. Catechins also give green tea its signature texture, and as a potent antioxidant, hinders dangerous free radicals in the body. Caffeine gives green tea its bitter taste, while increasing alertness, and relieving fatigue. Theanine, an amino acid, gives green tea its taste and acts as a mild relaxant. Theanine helps to relieve the jittery effect that caffeine can sometimes produce in sensitive individuals. This makes it a great alternative to coffee which not only has higher levels of caffeine, but does not contain theanine to regulate the unpleasant physical side effects. These are the main research properties included in green tea. Green tea contains a well-balanced mix of these ingredients.
      
    Health Benefits of White Tea

    White Tea is the least oxidized of all types of tea. Because of this and the higher proportion of young bud leaves, white tea is usually very low in caffeine, which makes it a good choice for people who are watching their caffeine intake. Many people believe white tea to be even better for you than green tea because it has been processed less. Research has shown that white tea contains the same free radical fighting catechins as green tea. White tea may help to prevent heart disease, cancers and stroke, as well as helping to treat diabetes. High levels of calcium and fluoride may help maintain healthy teeth, gums and bones. White tea is an excellent addition to your daily routine.

    Health Benefits of Oolong Tea

    Oolong Teas are unique because they span an oxidation range of 20-80%, where some are closer to green teas, and others are more similar to black teas. Caffeine levels vary accordingly, where greener oolongs will have less caffeine content and darker oolongs will have higher caffeine content. Oolong teas, because they have higher oxidation levels than green tea, will also have lower catechin levels, although catechins are still present. However, although catechins decrease with oxidation, theaflavin and thearubigin levels increase. These polyphenols may help in defending the body against stroke, dementia, heart disease and cancer. In addition to this, oolong teas have long been believed to aid in digestion, so have a cup with or after your next meal.

    Health Benefits of Black Tea

    Black teas contain the highest levels of caffeine among all types of tea. For someone who is looking for an efficient energy boost, this would be a great choice. However, for caffeine sensitive individuals, consumption of black tea should be moderate. Black tea does contain low levels of catechins, but is noted for having the highest levels of theaflavins and thearubinins. As more research is showing, these compounds may be just as effective as the catechins in green tea in preventing heart disease, stroke and cancer, and lowering cholesterol. So don’t think that that your morning black tea isn’t as healthy as your cup of green tea in the afternoon. You are just consuming a different variety of healthy compounds.

    Health Benefits of Pu-erh Tea

    The unique processing of Pu-erh teas, where the leaves are literally fermented and aged, chemically changes the makeup of the tea. Pu-erh tea has varying, but generally low levels of caffeine. It also contains very high amounts of flavonoids, which are aggressive in lowering LDL cholesterol and lowering blood pressure. Studies have shown that pu-erh has the ability to break up fats, which makes this tea especially effective at aiding digestion after particularly heavy or greasy meals. Traditionally, this type of tea was also believed to aid in weight loss, and is now included in many “slimming” tea formulas. Recent studies have shown that this type of tea may decrease body mass and increase metabolism. While it may or may not aid in maintaining a healthy weight, the other benefits to the heart and body are important enough to consider trying this unique tea.

    Health Benefits of Herbal Tea

    Herbal “teas” or tisanes are not true teas, because they do not derive from the Camellia sinensis plant, however these tisanes have some virtues of their own. Most notably, these infusions do not contain caffeine, which makes them acceptable for young children, the elderly or for evening tea drinking. A specific example, rooibos, a red bush from South Africa, has high levels of antioxidants and vitamin C, as well as being caffeine free. Lavender has been used for generations to promote relaxation and to calm the mind and body. Chamomile, while also having strong calming powers, has been used as a natural pain reliever when prepared in strong infusions. Peppermint is used by many traditions, especially in Moroccan culture, as a tea to help aid in digestion and to clear the sinuses. These herbs, while not having the super powers of the Camellia sinensis plant should not be overlooked, as they do have their own more subtle benefits and can be enjoyed by anyone at any time of the day.

    Bad Effects and Safe Zones

    Black tea is safe for most adults. People who drink black tea or other caffeinated beverages all the time, especially in large amounts, can develop psychological dependence. Caffeine is probably safe in children in amounts commonly found in foods
