The esophagus is the muscular tube that carries food from out throat to the stomach. Based on current statistics, cancers of this tube kill more than half a million people worldwide every year. There are many factors that have been thought to trigger esophageal cancer; nutritional deficiencies, infections and dietary toxins. Despite the wide speculative belief that it's alcohol and tobacco that cause throat and esophagus cancer, other populations have also had a high rate of this disease; populations that do not drink or smoke. It is with a new study that a new risk has finally come to light. There has been a rise in esophageal cancer among countries where it is traditional to drink black tea above 70ºC (or 158ºF).
Testing & Studies in Temperature of Teas
Iranian researchers have found that drinking this hot tea can be linked to the increased odds of developing cancer of the esophagus and they have provided what most believe is the most conclusive research; the hypothesis that thermal injury can cause cancer. Northern Iran has one of the highest rates of the most common types of esophageal cancer. It is here that a team from the University of Tehran set up a case controlled study of a single area in northern Iran, the Golestan Province, to better understand the spread of esophageal cancer.
The team found that smoking tobacco products and drinking alcohol is an uncommon trait in this population but tea drinking is common. Past studies did not provide suitable data. It was difficult to distinguish whether the negative factors of tea drinking were because of drink temperature or type of beverage consumed. There was also insufficient evidence where the temperature of the tea was rated by the drinker without independent confirmation.
A Difficult Test Procedure Finally Pays Off
To address the issues of the previous studies, the researchers studied tens of thousands of people in the Golestan Province. The subjects of the study drank, on average, a liter of black tea per day each, and temperatures, along with the speed at which it is drunk, were measured. The study has now been printed in the BMJ (formerly The British Medical Journal). Professor Reza Malekzadeh, the leader of the researchers, explains that "Our results showed a noticeable increase in risk of esophageal squamous cell carcinoma associated with drinking hot tea." The team discovered that the tea itself did not constitute a risk of cancer, but as the temperature increases so does the risk.
Common Sense Might Just Save You from Cancer
Having tea around 65ºC compared to consuming tea above 65ºC but below 70ºC increases odds of esophagus cancer twice, while consuming tea at over 70ºC increases the risk eight times over. The time in which the hot tea was drunk also plays a part. Drinking tea about four minutes after it's poured decreases the chances of developing esophagus cancer. This can be seen as using common sense and it should be taken to heart. It is best to allow five to ten minutes between making and pouring a hot beverage and this not only applies to tea, but any high temperature food or drink. Any hot beverage or food should be allowed to cool before drinking or eating to better protect your esophagus, and lessen the risk of cancer. Adding milk to hot drinks such as tea and coffee, as is common practice in the West, adequately cools the beverage enough to eliminate the risk.
When it comes to the amount of speculation, experimentation, research, clinical studies, and proven benefits of green tea, --it's almost intimidating getting to know all the facts. The main conclusion here is that green tea is good for you; it has anti-aging qualities, and prevents various illnesses. One example, and possibly the most serious of these kinds of health problems, is cancer. Cancer is one of the leading causes of early death currently. According to statistics, around three hundred people die of cancer every day, --and those numbers just cover the United States. But there's good news, because the antioxidants in green tea help prevent various kinds cancer, among other health problems.
Green Tea & Lung Cancer
Most forms of cancer are preventable, --not curable, but preventable, through clean living, not smoking, and basically, just keeping your body in good condition. And we all admit, that's easier said than done. Not everyone wants to wear sunscreen, even though it can prevent melanoma, and not everyone wants to quit smoking, --even though smoking is the leading cause of lung cancer. As it turns out, green tea might even be able to help smokers protect themselves from lung cancer.
Research on Green Teas Preventative Qualities
The scientists at the Toxicology Research Center in Korea have studied the effect of green tea on the lungs; they've found that it may protect the delicate tissues of the lungs, even under the heavy damage done by smoking. The four groups tested in the study were smokers consuming green tea, smokers who consume coffee, non-smokers, and smokers who consumed neither green tea nor coffee; all the smoking participants had been smoking for around 13 years. Rest assured, they weren't working with people who had just bought their first pack of smokes.
After six months of drinking 2 or 3 cups of green tea every day, the smokers returned, along with the other groups, for evaluation. This group, showed about as much SCE, (sister chromatid exchange) as non-smokers, making a significant reduction. This was the stand-out result; the other three groups weren't as impressive. SCE, by the way, is a cell process that is linked to the growth of tumors. Obviously, if green tea reduces the growth of tumors in the lungs, it's going to start becoming a lot more popular with smokers.
How You Can Stay Healthy with Green Tea
The scientists conducting the study concluded the same thing; smart guys, aren't they, --that green tea was preventative of lung cancer, even among smokers. And drinking coffee has no real effect on SCE levels, --so if you were worried that coffee causes cancer, feel free to keep drinking it. On the other hand, you may want to switch to some high quality green tea instead. It has just become extremely important that smokers drink green tea, --but not just people who smoke. Everyone is at risk for various kinds of cancers, so if green tea can actually help us prevent cancer and keep our bodies in good shape, we need to be drinking more.
The beneficial qualities that tea brings to both mind and body have long been recognized by the vast majority of people around the world. However it’s always the green leaf variety that takes the plaudits with other varieties playing second fiddle at best, and often times ignored. We are constantly bombarded through the media and treated to information overload to the extraordinary attributes of the green tea variety. It is certainly then no surprise that it is to green tea that one’s thoughts first turn while looking for a healthy drink to refresh. Whilst it is certainly true that green tea does come packed with an incredible health-giving pedigree, the black tea variety, or ‘crimson’ as it is known in Chinese and languages influenced by Chinese, should most certainly not be ignored.
What's the Difference?
Black tea has as much to offer as the green leaf variety to those that choose to give it a try. A fact of which many people are not aware is that both black and green tea comes from the same plant, Camellia sinensis. The larger leaves from the Assamese plant are used for the black variety, with the smaller leaves from the Chinese plants being used for green and also white tea too. Whilst much has been said of the health giving qualities of green tea, those benefits can be said to be present in black tea also as they are essentially derived from the same source. This is despite its more intense processing and consequently lower levels of antioxidant. There also tends to be more caffeine in black tea and hence black tea can be considered more stimulating.
It is often of a better flavor too as green tea tends to lose its flavor after a year or so, whilst black leaf tea can retain the flavor for many years more. It is due to this attribute of black tea that it has long been used a commodity for trading, and black tea bricks were even used as a form of currency in the 19th century in countries such as Mongolia, Tibet and Siberia. TF-2 is a compound present in black tea. It is an antioxidant and as such is very helpful to the human body in the fight against cancer, diseases of the heart and other inflammatory ailments.
Black Tea Research
Studies carried out in Europe spanning a decade have shown that drinking in excess of 2 cups of black leaf tea a day can cut in half the incidence of heart problems in males. The best method by far with which to imbibe tea is in its loose form, and in the authors opinion the bagged variety should be kept firmly on the shelf. It’s not just a great flavor from which you will benefit with black tea but also the extraordinary health-giving benefits that it will bring to your body. And there are of course many brands from which to choose with varied tastes and flavors. All without exception compete admirably with their green leaf counterparts in health properties and arguably make a more enjoyable and flavorsome drink.

Many people around the world, including chefs and even scientists believe that white tea has numerous benefits towards everyone’s health. But do you really know what exactly white tea is and how you could benefit from white tea leaves? The immature tea leaves are alternatively called white tea. These loose leaves are picked from the tea plant just before the plant has fully bloomed. The name ‘white tea’ came from the fine silvery fuzz covering the tea leaf and making it white in color. The four distinct varieties of white tea include the White Peony, Silver Needle, Long Life Eyebrow and Tribute Eyebrow. The difference between them is the proportion in which the tea leaves are blended with the tea buds.
Harvesting White Tea
Usually buds turn into tea in two days after they are picked. When two tea leaves are mixed with one tea bud, it forms the White Peony and if the mixture is made completely of buds, it is termed as the Silver Needle tea. The low quality tea variety called Long Life Eyebrow is made by mixing up the left over leaves after the White Peony and Silver Needle harvest. Tribute Eyebrow is processed using a special tea bush and is also a lesser quality tea. All four white teas can be purchased in loose leaf forms. On the other hand, teas available in bags have comparatively less quality and flavor than white tea. Tea bags are generally tea leaf dusts that remains at the bottom of tea bins after harvesting, reducing the desired quality and flavor.
White Tea Research
Scientific research has also shown that white tea provides additional protection against skin cancer, colon cancer, stomach cancer and even prostate cancer. Studies on the effect of white tea extract on skin exposed to direct sunlight has shown improved protection and reduced cell damage. A partially repaired immune system was also observed in some test subjects that consumed white tea leaves. Scientists found a wealth of antioxidants present in white tea and they suggested it may have anti-aging effect. Some compelling evidence has also been found in the direction of disease prevention using white tea leaves. It is shown that the white tea leaf extract may have the ability to stop pneumonia and the bacteria that causes Staph infection. It is also used to prevent tooth decay, gum disease, plaque and even bad breath.
What Else Can White Tea Do for You?
It is also believed that white tea leaf has anti-fungal effects. Recent studies have shown that some fungal types became inactive when the fungal drugs are consumed along with white tea leaves. Results of this study also show that white tea leaves might be used to prevent the fungus growth in certain similar conditions. Cholesterol is a health requirement and there are two kinds of cholesterol: good cholesterol and bad cholesterol. It is the bad cholesterol that causes the hardening of the arteries that could lead to heart attack. A type of antioxidants called catechins has been found to reduce bad cholesterol; white tea also helps raise the good cholesterol in the human body. It has been suggested that white tea leaves could lower the blood sugar levels, and thus reduce the occurrence of diabetic symptoms. More scientific research and results can be expected in the near future as the research on white tea continues.
