Hot Tea May Raise Esophageal Cancer Risk

by Elena Popec 31. May 2010 10:39

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.

Health Benefits of Tea

Health Benefits

Were you aware that our nation drinks approximately 165 million cups of tea daily? Millions of people love the taste of tea, but many of us are not aware of the healing powers tea can actually give us.

Tea is not only delicious, it can also help prevent High Blood Pressure by controlling angiotensin, which eventually leads to high blood pressure, according to health experts.

Studies have shown that drinking tea can also provide us with protection against cancer, heart disease and it can also aide in preventing memory impairment conditions such as Alzheimer’s.

 

Healthy Antioxidants within Tea

Flavanoids generally found in vegetables and fruits; contain powerful antioxidants such as Vitamin C and E.  So, one cup of tea actually contains twice as many of these Flavanoids as one apple.

You often hear about the importance of consuming fruits and vegetables, but rarely are you encouraged to drink tea - maybe more of us should.

Consuming tea and its healthy antioxidants provides us with antiviral, antibacterial, anti-inflammatory, and antiallergenic benefits. 

Drinking tea also has the benefit of helping improve concentration thus improving performance. Concentration is improved due to the caffeine that is within tea. The caffeine makes you more alert and focused.

Tea is also a natural source of fluoride; therefore it helps to keep teeth and gums healthy.  Because tea contains this natural source of fluoride, it can help prevent certain gum diseases and tooth decay. 

 

The Power of Green Tea

The Chinese have been using the healing effects of Green Tea for centuries, 4,000 years in fact. Only in the past 20 years other parts of the world began to take notice of this herbal treatment for headaches, depression, and beyond.

In 1994, a study was conducted that revealed Green Tea could possibly reduce esophageal cancer risks by 60%. Numerous other studies have been performed as well to establish the health benefits of consuming Green Tea and to learn why the herb is so healthy.

Clinical studies conducted over the years have found that Green Tea, or the herbs that create Green Tea, contain powerful antioxidants. Many believe that it may help prevent cancer cell growth, but to also selectively eliminate cancer cells. This is especially amazing because the powerful herb does not attack the healthy cells around the cancer cells.

Green Tea can also be efficient in lowering the bad cholesterol, LDL, levels while boosting the good cholesterol, HDL, levels.  By doing this, Green Tea is improving the ratio of good to bad cholesterol and possibly helping to prevent the onset of heart disease.

The Chinese have shown us many healing teas, but Green Tea is by far the best healing tea that has been introduced to us. Because Green Tea leaves are steamed, they are able to hold on to their potent antioxidants.

Green Tea as well as Fruit Blends, Rooibos, Herb Blends and Ayurvedic are fairly inexpensive and is well worth the cost for all of the potential healing effects and preventative abilities it has.

 

Drink Black Tea for a Healthier You

Black Tea, although made from the same plant as white and green tea, is almost completely different. Black Tea, unlike Green Tea and White Tea, is processed and fully oxidized.  Although from the same plant, what happens to the tea leaves after picking is what sets the three apart.

Black tea does not hold as many health benefits as Green Tea, but it still has retains enough to make it a smart choice for drinking. One reason why it’s considered the smart choice is simply because most studies have been only conducted on green tea. This is because it is the most consumed tea in the world.

The antioxidants in Black Tea can help protect against free radicals damage that generally leads to disease. Some properties of Black Tea have been shown to slow the growth of cancer cells but not effecting the growth of healthy cells.

The fact that the properties in the tea have the ability to selectively target the cancer cells and not the healthy cells is truly amazing.

 

Drinking Tea May Slow Down the Aging Process

Drinking Black Tea has also been said to slow down the aging process. Look at the anti-aging lotions and serums on the market today and you will find that many contain tea leaf extracts. Black Tea also is known to help rev up metabolism and fat burning. This is even more so when used in conjunction with caffeine and exercise.

To lower your LDL, bad cholesterol, studies have shown that drinking Black Tea is beneficial in doing so as well as helpful in increasing your HDL, healthy cholesterol. Drinking tea can help balance the ration of good and bad cholesterol and help to ward of heart disease.

If you are diabetic, drinking tea can aid in lowering glucose levels. Lowering your glucose levels will also lower your risk of conditions brought on by diabetes such as cataracts. Start drinking tea today for a healthier you tomorrow!

 

Rooibos

Rooibos in Afrikaans is translated as “red bush”.  This has a very sweet taste and it is frequently used as a base tea to blend tea.  It is rich in antioxidants and it is caffeine free. Here are a few health benefits of Rooibos:

 

·         Contains a host of vitamins and minerals such as copper, potassium zinc, calcium, potassium and manganese.

·         It is anti-viral, anti-mutagenic, anti-inflammatory and anti-carcinogenic activity.
