Health Benefits of Black Tea | Best Health And Food Tips
January 30, 2017 10:19 AM
We have known for a while that tea is better for us than some other beverage options. However, are some teas better than others? There is evidence to suggest that black tea has a better ability to improve immunity, reduce stress, and improve digestion. The polyphenols in tea are also quite effective at getting rid of bacteria in the mouth and maintaining good oral hygiene. Black tea also has more antioxidants than other forms, making it better at fighting illness and cardiovascular issues. Many of us drink it for the energy boost, but there are so many other benefits.
"Black tea is a type of tea that is more oxidized than oolong, green and white teas. Black tea is generally stronger in flavor than the less oxidized teas."
The Benefits of White Tea!!
November 23, 2012 01:25 PM
white tea is a special variety of lightly oxidized tea which has undergone very little processing. It is originally native to China and in recent times it has been cultivated in Nepal, Thailand and Taiwan. white tea has been popular in China for over a thousand years and was the preferred drink of the rich elite of the nation. It came into prominence during the reign of the Soong dynasty. It was considered precious and was presented as tribute to the Emperor.
According to legend Emperor Hui Zong lost most of his kingdom in his pursuit for the perfect white tea. white tea is an integral part of Chinese history and was a part of many of their traditional ceremonies. The rest of the world has only recently adopted this exotic beverage.
How Is It Produced?
white tea is derived from the Cammelia senensis plant and takes lot of time and effort to produce properly. The leaves and buds of the plant are carefully steamed and subsequently dried. It is not processed or rolled extensively like black or green tea. This makes white tea lightly oxidized and this unprocessed quality may be the reason for its numerous health benefits. We look at some of the health benefits associated with white tea.
An Antioxidant And More!
white tea contains antioxidants which help in protecting the body from harmful free radicals. These free radicals accelerate aging and damage DNA. white tea has substances which are effective against malignant cells and can help treat stomach, colon and prostate cancers. Flavonoids are a special variety of antioxidants which restrict the growth and development of cancerous cells. white tea has been shown to help in lowering blood pressure and promoting arterial functioning. It causes a reduction in the consistency of the blood and promotes smooth blood circulation. It protects against stroke by promoting a healthy circulatory system.
Active Ingredient Catechins:
Catechins are another group of antioxidants, which can help regulate cholesterol levels in the body. These antioxidants reduce bad cholesterol and prevent the arteries from hardening. white tea drinkers are reported to have greater strength and bone density. Also drinking white tea has shown positive effects for people suffering from bone related disorders like osteoporosis and arthritis.
This tea provides natural defensive against viruses and bacteria. It is conducive for the health of the immune system and provides protection against a variety of immune disorders. white tea contains small amounts of fluoride compounds which help keep your teeth healthy and clean. It eliminates the bacteria responsible for bad breath, tooth decay and plaque. It removes free radicals from the tissue and reverses the effects of weather, stress and poor dietary preferences to give you healthy glowing skin. white tea has many other health benefits to offer.
Its consumption is linked to increase in metabolism, weight loss and reduction in the symptoms associated with type-2 diabetes. white tea is a natural product free from excessive processing and harmful chemicals. It offers many health benefits and does not cause any harmful side effects. It is slowly gaining popularity as a health supplement among the global population.
Polyphenols is an Antioxidant
October 13, 2008 02:14 PM
A lot of new evidence suggests that consuming more plant polyphenols is a powerful way to protect aging arteries. These polyphenol compounds help improve endothelial function, a critical factor in preventing atherosclerosis; inhibit abnormal platelet aggregation which causes most sudden heart attacks and strokes; fight inflammation; and support healthy blood lipids. Polyphenols that are of particular interest are those derived from green tea, cocoa, apples, and black chokeberry, which all complement each other in helping to build the body’s defenses against various ailments.
All throughout history, the medicinal potential of plants has been celebrated. Modern science has found that edible plants are to be valued for their high vitamin and fiber along with their rich store of polyphenols. Polyphenols are found in fruits and vegetables, as well as cocoa, tea, and chokeberry and have been shown to be a type of chemical that may protect the body against some common health problems as well as certain effects of aging. Polyphenols protect cells and body chemicals against damage that is caused by free radicals and block the action of enzymes that cancers need for growth, deactivating substances that promote the growth of cancer. The increased consumption of polyphenols has been associated with a reduced risk of cardiovascular disease and potentially cancer and stroke.
In Aztec culture, cocoa was one of the most highly prized due to its medicinal and stimulant value, along with its taste. The polyphenols found in cocoa occur in a higher concentration than can be found in any other food. They also have antioxidant activity much greater than those found in broccoli or red wine. The catechins and procyanidins that are found in cocoa seem to lower the risk of cancer and heart disease. Cocoa has also been proven in studies to reduce blood pressure, improve insulin sensitivity, and slightly ameliorate the lipid profile. Although cocoa is a healthy and tasteful food, it is high in caloric content and therefore, its ingestion must be accompanied by the careful reduction of calories from other sources.
Many studies have shown that tea polyphenols can be extremely beneficial to human health, possessing anti-obesity, antihypertensive, anti-diabetic, antioxidant, anti-inflammatory, and anticancer effects. Tea is the world’s second most consumed beverage, although less popular in the Western diet. Green tea and white tea retain more polyphenols in their intact form, as oolong and black teas undergo more extensive processing before they are marketed. Tea polyphenols break down in high temperatures therefore; freshly brewed tea contains a higher amount of polyphenols per serving than do tea drinks that are canned or bottled.
Similar to the blueberry, the black chokeberry is high in anthocyanins and antioxidant activity. It is native to eastern North America and has become popular in Eastern Europe and Russia due to its health-promoting potential. This berry protects the liver from chemical poisoning and the stomach lining from ulcers. It also acts as an anti-inflammatory, lowers harmful cholesterol levels, and prevents dangerous swings in blood pressure. Some studies have shown that this berry seems to prevent the harmful mutations in cell cultures, regulates immune function of human white blood cell cultures, and suppressed the growth of human colon cancers.

Tea is soaked in culture and history, with its roots dating back to ancient China. Chinese legend says that tea was created more than 5,000 years ago when the leaves fell into the boiling water of an early emperor. From there, tea has become a popular drink, with a culture of its own. True teas are made from the dried leaves of the tea plant, which was first cultivated in China and found growing wild in India. The different processing techniques are used on the leaves of the tea plant in order to produce the many different styles. Green tea is produced by steaming the fresh-picked leaves, followed by heat-drying, while black tea is made by allowing the tea leaves to ferment completely before firing. Oolong teas are made by partially fermenting the leaves before firing while white tea is the least processed of all the teas, with it not being oxidized or rolled by instead, dried by steaming.
Anything that doesn’t come from the Camellia sinensis plant is known as an herbal tea. Herbal teas contain herbs and spices that are often used for health purposes. Rooibos, which is the popular herbal tea, is also referred to as red tea, is full of polyphenols and flavonoids which help reduce cellular damage that is caused by free radicals which weaken natural defenses. Red tea also contains many beneficial vitamins and minerals and helps to reduce cramping and gas.
Other herbal tea blends are made for various symptoms such as PMS, energy, weight control, and detoxing. An herbal tea blend that is comprised of astragalus, cranberry, rooibos, and three types of Echinacea can help to support the body’s natural defense system. Peppermint blend teas alleviate digestive disorders and insomnia, while Holy Basil tea helps to alleviate stress, lowers cortisol levels, and promotes a sense of well-being. All ingredients in an herbal tea have a purpose. The herbs and spices improve well-being and contribute to an active, balance, and healthy lifestyle.
A quality herbal tea looks at several aspects of the ingredients. Each herb is looked at for its medicinal value before being included in a tea. Higher quality herbs mean that a higher price is paid for the starting bulk materials, making the price of the finished tea product more expensive. Where the herbs are grown, how they are grown, and how they are harvested are all very important pieces of information to tea makers, who all want the best quality available for their tea formulas. The most important fact to tea makers is that the herbs are organic, and if they’re not organic, that they are wild-crafted, meaning that they go through quality control procedures to make sure that there are no chemical pollutants, heavy metals, or toxins in them.
Finally, the cut of the herbs is also especially important when creating teas, with tea bag cut producing the most effective single serving healthful tea. A tea bag cut means that they are small enough to be broken down and extract all the valuable components are able to be extracted out of the herbs in the shortest amount of time. Herbs should also be large enough that they don’t pass through the filter bag and leave residue in the cup. Herb quality and freshness is also very important, with the color of the herbs being vibrant and the smell obvious.
Fruit and Vegetable Lightning drink mixes from Natures Plus

Enjoy the Rainbow – the Color Wheel of Fruits and Vegetables
We’ve all heard the statistics, and have probably seen the signs in the produce section of our favorite grocery store: eating 5 servings of fruits and veggies a day is important,
Chances are also pretty good that we’ve also seen the newest food pyramid, encouraging Americans to “eat a rainbow of frits and vegetables.” That is, choose from the rich variety of colors for the best all-around health benefits.
In this Ask the Doctor, we’re going to look at the unique health components of different colored fruits and vegetables, and why they’re so important. Plus, we’ll learn about supplemental options, like fruit and vegetable drink mixes, for those days when our diets just aren’t that great.
Q. What’s the big deal about fruits and vegetables?
A. Well, for the main reason that they are whole foods – created by nature (or at least generations of farming) and are rich in a variety of nutrients. Processed foods can’t match the health benefits of strawberries or broccoli – items that have fiber, vitamins, and enzymes built right in.
Q. What does “eating a rainbow” of fruits and vegetables really mean?
A. This is simply an easy way of remembering to get as much color variety in your diet as possible to maximize your intake of a broad range of nutrients. The colors of fruits and vegetables are often a tangible clue to the unique vitamins and other healthy substances they contain. Getting a variety of colors, therefore, means getting a variety of the essential nutrients your body needs to stay healthy and strong.
Enjoying the Rainbow: Fruit and Vegetable Benefits:
Q. Can you tell me a little more about the healthy components of fruits and vegetables?
Let’s take a look at some of the most well-studied and important nutrients:
Quercetin is found in apples, onions and citrus fruits (also is hawthorn and other berries and apple-related fruits usually used in traditional herbal remedies and modern supplements). It prevents LSL cholesterol oxidation and helps the body cope with allergens and other lung and breathing problems.
Clinical studies show that quercetin’s main points of absorption in the body appear to be in the small intestine – about 50%. The rest – at least 47% is metabolized by the colonic micro flora – the beneficial bacteria such as Lactobacillus acidophilus and Bifidobacterium longum. You may consider adding these beneficial bacteria (found in yogurt) either through the diet or a supplemental form.
Ellagic Acid is a component of ellagitannins – dietary polyphenols with antioxidant (and possibly anticancer) properties. Polyphenols are the basic building blocks of many plant-based antioxidants. More complex phenolic compounds, such as flavonoids are created from these molecules.
Ellagic acid is found in many fruits and foods, namely raspberries, strawberries, pomegranates, and walnuts. Clinical studies suggest that ellagitannins and ellagic acid act as antioxidants and anticarcinogens in the gastrointestinal tract.
Ellagitannins are durable antioxidants, and happily, they do not appear to be diminished by processing, like freezing. This means the benefits are still strong, even in frozen packs of raspberries or strawberries, or some of the better multi-ingredient supplement drink mixes.
In scientific studies, ellagic acid also showed an anti-proliferative effect on cancer cells, decreasing their ATP (adenosine triphosphate) production. ATP is the molecule that provides the primary energy source for the cells in our bodies. In a sense, ellagic acid seems to deprive cancer cells of their fuel.
Beta-Carotene: Probably the best-known of the carotenoids, beta-carotene is converted by the body into vitamin A. Many vegetables, especially orange and yellow varieties, are rich in this nutrient. Think summer squash, yams and of course, carrots.
Beta-carotene has long been associated with better eyesight, but it has other benefits, too. In a scientific study, beta-carotene decreased cholesterol levels in the liver by 44% and reduces liver triglycerides by 40%.
Lycopene is a carotenoid mostly found in tomatoes, but also in smaller amounts in watermelon and other fruits. Clinical studies have shown that lycopene consumption may decrease the risk of prostate cancer. In fact, high intakes of lycopene are associated with a 30% to 40% reduced risk. And, as good as beta-carotene is, its cousin, lycopene, seems to be an even stronger nutrient, protecting not just against prostate cancer, but heart disease as well.
Lutein is found in many fruits and vegetables, including blueberries and members of the squash family. Lutein is important for healthy eyes, and in fact it is found in high concentrations naturally in the macular region of the retina – where we see fine detail. It is one of the only carotenoids, along with its close sibling zeaxanthin, that is found in the macula and lens of the eye.
Lutein also supports your heart, too. In a scientific study, lutein reduced atherosclerotic lesion size by 43%. In other words, high intakes of lutein may actually help prevent coronary artery disease!
Interestingly, as is the case with lycopene, cooking or processing foods with lutein may actually make it more easily absorbed.
In clinical studies, men with high intakes of lutein (and its close cousin, zeaxanthin, found in broccoli and spinach) had a 19% lower risk of cataract, and women had a 22% decreased risk, compared to those whose lutein intakes were much lower.
Vitamin C: One of the best-known nutrients out there, vitamin C keeps our immune system strong; speeds wound healing, and promote strong muscles and joints. A free-radical fighter, vitamin C prevents oxidative damage to tissues, builds strength in collagen and connective tissue, and even reduces joint pain.
Sources of vitamin C are scattered throughout the spectrum of fruits and vegetables.
Potassium: Most Americans are deficient in potassium. For the most part, it’s hard to get too much of this valuable mineral. Potassium does great things for our hearts. Higher intakes of dietary potassium from fruits and vegetables have been found in clinical research to lower blood pressure in only 4 weeks.
Many researchers believe that the typical American diet has led to a state of chronic, low-grade acidosis – too much acid in the body. Potassium helps change pH balance to a more alkaline environment in the body and increases bone density.
This was proven in the long-running Framingham Heart Study which showed that dietary potassium, (along with magnesium and fruit and vegetable intake) provided greater bone density in older individuals.
Fiber is another food component many just don’t get enough of – especially if they’re eating a “typical American diet.” Fruits, vegetables and whole grains are excellent sources of fiber. However, fiber from a good fruits and vegetable drink mix should be derived from inulin and chicory root. This soluble fiber source not only adds to the overall amount of fiber you need (25 to 38 grams a day), but also provides a nice “nesting ground” for the beneficial bacteria that populate the intestines. And, even though some fiber has a bad rap for inhibiting mineral absorption, inulin and chicory root are “bone building” fibers – they actually help the body absorb calcium.
Flavonoids are an overarching term that encompasses flavonols, anthocyanidins, and flavones, isoflavones, proanthocyanidins, Quercetin and more. They are almost everywhere: in fruits, vegetables, grains, herbs, nuts and seeds – even in the coffee, wine and tea we drink. Flavonoids are responsible for the colors in the skins of fruits and the leaves of trees and other plants.
Flavonoids have many health benefits. They can help stop the growth of tumor cells and are potent antioxidants. Additionally, flavonoids have also been studied for their ability to reduce inflammation.
Anthocyanins: High on the list of important “visible” nutrients are anthocyanins. They color fruits and vegetables blue and red.
Anthocyanins are members of this extended family of nutmeats, the flavonoids. Typically found in high amounts in berries, anthocyanins are readily absorbed in the stomach and small intestine.
As antioxidants, anthocyanins dive deep into cell membranes, protecting them from damage. IT may be one reason why the anthocyanins from blueberries are considered such an important component in battling neuronal decline, like Alzheimer’s. Blackberries, raspberries, and strawberries are also excellent sources of this flavonoids group.
SDG lignans, (short for secoisolariciresinol diglucoside) are polyphenolic components of flaxseed, pumpkin and other herbal sources. Much of the recent research surrounding lignans has focused on flaxseed. In scientific and clinical studies, lignans from flaxseed support hormonal balance and may have cancer-preventing abilities. In fact, in one study, flaxseed lignans reduced metastatic lung tumor by 82% compared to controls.
The lignans in pumpkin seed, also considered a major source, target 5-alpha reductase activity.
This enzyme catalyzes the conversion of testosterone into the more potent dihydrotestosterone (DHT). DHT, like testosterone, is a steroid hormone or androgen. Androgens are responsible for the development and maintenance of masculine sex characteristics in both men and women. Excess levels of DHT can cause serious problems with prostate or bladder health. That’s why modulation of the 5-alpha reductase enzyme is so important – it helps maintain healthy testosterone and DHT levels. By balancing the levels of these key hormones, pumpkin seed lignans provide protection for prostate and bladder cells.
In addition, pumpkin seed has been shown to modulate the enzyme aromatase. Aromatase is present in the estrogen-producing cells of the adrenal glands, ovaries, testicles, adipose tissue, and brain. Aromatase converts testosterone, an androgen, into estradiol, and estrogen.
Inhibition of the aromatase conversion can help maintain a balance of healthy testosterone levels in women, which has been shown to strengthen pelvic muscles and reduce incidence of incontinence.
In fact, a clinical study, involving a pumpkin extract in conjunction with soy, resulted in significant support for bladder health. After two weeks of supplementation, 23 of the 39 postmenopausal women enrolled in the study showed great improvement in urinary frequency and sleep. By the end of the six week study, 74.4 percent of participants found pumpkin extract safely and significantly improved “nocturnia,” that is, the need to urinate frequently at night. For individuals with 2 to 4 episodes of nocturnia prior to the stud, and 81.8% improvement was seen – also showing great improvement in sleep quality. After all, if you don’t have to wake up every couple of hours to go to the bathroom you’re bound to get better sleep.
Beta glucan: Mushrooms are intense immune-boosting powerhouses due to their beta-glucan content. Three well-studied power-house mushrooms that contribute beta glucan to the diet include maitake, reishi and shiitake.
The most significant constituents of mushrooms are long chain polysaccharides (molecules formed from many sugar units) known as beta-glucan. These huge molecules act as immunoregualtors in the human body, helping to stabilize and balance the immune system.
This includes specific support of white blood cells, or lymphocytes, the primary cells of the immune system. Lymphocytes fall broadly into three categories: T cells, B cells, and natural killer (NK) cells.
In one clinical study, 165 patients with various types of advanced cancer were given maitake mushroom compounds alone or with chemotherapy. Cancer regression or significant symptom improvement was observed in 58% of liver cancer patients, and 62% of lung cancer patients. Plus, when maitake was taken in addition to chemotherapy, the immune cell activities were enhanced 1.2 to 1.4 times, compared with chemotherapy alone.
In another clinical study, researchers determined that Reishi increased the number of cancer killing white blood cells and made them more deadly to cancer cells.
And, in a scientific study of human breast cancer and myeloma cancer and myeloma cancer cell lines, shiitake compounds provided a 51% antiproliferative effect on the cells – inducing “apoptosis’ – the programmed cell death that should occur naturally.
While beta-glucan are distributed throughout the mushroom body, the beta-glucan concentrations are significantly higher in the mycelium – the interwoven fibers or filaments that make up the “feeding structure” of the mushroom.
Bioflavonoids are commonly found in bright yellow citrus fruits, including lemons, limes and oranges. They are responsible for the bright pigment found in the skin of the fruit, and are considered a “companion” to vitamin C, seeming to extend the value of the nutrient within the body.
Hesperidin is just one of the valuable bioflavonoids found in citrus. Hesperidin appears to lower cholesterol levels, as well as support joint collagen in examples of rheumatoid arthritis.
Epigallocatechin gallate (EGCG):
Polyphenols, most notably EGCG, or epigallocatechin gallate, are well-studied and powerful components of tea. EGCG has been shown to reduce colon and breast cancer risk. Green tea also boosts the immune system and encourages T-cell formation – part of the front-line defense of our bodies against sickness and disease.
Q. I’ve been seeing articles about fruits, vegetables and supplements touting “high ORAC value.” What does this mean?
ORAC is an acronym for Oxygen Radical Absorption Capacity, and is simply a measurement of antioxidant activity of nutrients. Oxygen radicals, or free radicals, are unstable molecules. They grab electrons from other cells to use for themselves, and in the process can damage them. It is believed that free radical activity plays a role in the development of many diseases such as heart disease and cancer, and also plays a role in aging.
Antioxidants help prevent this damage by “loaning out” extra electrons to stabilize free radicals/ Consider any fruit or vegetable with a high ORAC rating as having a lot of “antioxidant power.”
I know I should eat more fruits and vegetables, but it just seems so hard to get five servings a day.
The number one excuse I hear for not buying frits and veggies is that “fruits and vegetables are too expensive.” But are they really? Certainly, fresh foods that aren’t in season and have to be shipped a distance can be a bit pricey. If anyone added up how much spend on fast food, or prepackaged or processed snacks, it would probably be shocking.
Luckily, there are many ways to get your “Daily 5”. For instance, frozen fruits and veggies retain much of their nutrient profile. They can be an excellent alternative when certain foods are out of season. So too, are fruit and vegetable drink mixes – excellent supplemental sources of some of the nutrients our bodies need most.
More recently, the American
Of course, for people not accustomed to the fiber in fruits and veggies, there is some reason to think it’ll increase gas. When cell walls break down, and fiber passes through the system, it can create flatulence. Folks who eat fruits and vegetables every day generally don’t have this problem. Their systems are already accustomed to it.
For those just starting out on a better diet, however, start slowly – it helps your body adapt. Cooking vegetables can help, too, because it begins breaking down the cell walls early on.
One thing is certain, however. The “Typical American Diet” and good health are mutually exclusive. The increase in type 2 diabetes, heart disease, high cholesterol, and hypertension all point to the abuse our bodies suffer by eating diets high in fatty meats, processed sugars, and refined grains.
Q. Can I just drink fruit and vegetables drinks in place of 5 servings of fruits and vegetables?
Green drinks and fruit and vegetable drink mixes aren’t meant to replace whole foods, but they can be an excellent substitute when you’re rushed or traveling or just trying to fill everyday nutritional gaps. Their whole food ingredients absorb very easily and gently in the gut, and many of these drink mixes contain healthy doses of fiber, too.
Green drink mixes and food-based drink mixes combine many colorful fruits and vegetables and sometimes grasses in a healthy, mixable supplement assortment. While there have been many advancements in the field of green drinks, there are only a few that take the primary reason we eat into consideration: taste!
Happily, there are some companies out there with great-tasting drink mixes that also formulate based on the color concept, ensuring you get the broadest assortment of nutrients from a full range of fruit and vegetable colors to promote optimal health.
High-quality fruit and vegetable drink mixes offer the best from nature’s color wheel in a convenient and great-tasting supplement. So, the next tie you feel like taking a coffee break – try a fruit and veggie break instead. Your body and spirit will thank you.
Vitali-Tea - Tea fits a healthy lifestyle to a T...
June 13, 2005 09:45 AM
Vitali-Tea by Leah Brinks Energy Times, October 9, 2003
If the research is even only half right, tea fits a healthy lifestyle to a T. Whenever scientists look at a teapot's contents, they find striking health benefits: Heart protection. Reduced cancer risk. Better skin.
All of these are apparently in the bag when you choose to drink tea. Tea green, tea black: Which to choose? Actually, both types come from the same plant, Camellia sinensis. Green tea is steamed and dried; black tea is fermented, which allows its darker color to develop. Some lesser-known types include white tea, which is actually green tea that undergoes the most minimal of handling. (Another rare white tea, white cantaloupe, is rich in antioxidants.) Oolong is a tea that falls between green and black in processing and flavor.
One increasingly popular tea color, red, is not tea at all, but an herbal brew called rooibos (technically, herbal teas are known as tisanes). This South African plant yields a citrus-flavored beverage high in vitamin C. Other herbs known for yielding flavorful infusions include chamomile, used to promote sound sleep; peppermint, a digestion easer; and rose hips, which, like rooibos, combines healthy vitamin C levels with a delightfully zesty taste.
The evidence for tea's health benefits has practically boiled over. For instance, researchers at the University of Rochester have found that green tea substances inhibit the action of a molecule irritated by tobacco smoke, a toxin central to tobacco's cancer-causing danger. This action, say the scientists, may be the reasons that smokers who drink tea suffer less cancer (Chem Res Tox 7/21/03).
The Rochester researchers found that tea helps protect a cellular molecule called the aryl hydrocarbon (AH) receptor. Ordinarily, AH is frequently disturbed by toxic substances that cause cancer and other illnesses. Tobacco smoke (as well as the pollutant dioxin) interacts with AH to initiate cancer and other problems.
But at least two chemicals in green tea-epigallocatechingallate (EGCG) and epigallocatechin (EGC)-interfere with AH's harmful activity. These substances, flavonoids similar to healthful chemicals found in grapes, wine and cruciferous vegetables like broccoli, have been shown to lower cancer risk.
"It's likely that the compounds in green tea act through many different pathways," says Thomas Gasiewicz, professor and chair of Environmental Medicine and director of Rochester's Environmental Health Science Center.
In the Rochester study, Dr. Gasiewicz and his colleagues found that EGCG and EGC close down the AH receptor in cancerous animal cells and most likely produce the same benefit in human cells.
Still to be made clear is how tea is metabolized when the body digests tea, but the Rochester scientists are still peering through their microscopes and teapots to find out.
Scientists at the Linus Pauling Institute at Oregon State University have found that drinking green or white tea can significantly lower your risk of colon cancer as well the prescription drug sulindac, which has been shown effective for people at high tumor risk (Carcinogenesis 3/03).
"Tea is one of the most widely consumed beverages in the world, and recent upswings in the sales of green tea in the United States can be attributed to reports of potential health benefits against cancer and other chronic diseases," says Gayle Orner, an OSU research associate. "Teas exert significant protective effects in experimental animal models of skin, lung, esophageal, gastric, hepatic, small intestinal, pancreatic, colon, bladder and mammary cancer."
While many people today take aspirin and similar drugs that have been shown to lower cancer risk, this study shows that drinking tea and taking low doses of these drugs, called NSAIDs, can reduce the risk even further. (High doses of NSAIDs, while protective against colon cancer, can cause internal bleeding.)
"These are pretty exciting results," Orner says. "What's especially significant is that as far as we can tell consumption of tea has none of the side effects of NSAIDs, which can be severe, including bleeding, ulcers and even death."
In this research on animals, use of tea dropped the risk of cancer by about two-thirds. According to the lab results, drinking about three large cups of tea a day should provide significant cancer protection. Based on research in Japan that looked at how green tea lowers the risk of stomach cancer, the Linus Pauling scientists urge plenty of tea drinking: "The more the better."
Studies show that nations of tea drinkers have less trouble with their hearts than residents of places where tea is hardly ever brewed. And now research is starting to zero in on the substances in tea that benefit heart health.
A study of 240 Chinese men and women who have high cholesterol has found that chemicals in tea can significantly drop harmful cholesterol (Arch Int Med 6/23/03).
"Personally, I was very surprised," says David J. Maron, MD, professor at the Vanderbilt University Medical Center, lead author of the study. "I expected, if anything, a very slight cholesterol-lowering effect. But what we saw was a 16% reduction in low density lipoprotein (LDL) cholesterol."
LDL cholesterol is known as "bad" cholesterol because it can increase your risk of heart disease.
The researchers in this study gave people extracts of green and black tea enhanced with theaflavin, an antioxidant also found in green tea.
In the future, if past results are any indication, tea's rich supply of beneficial chemicals will continue to pleasantly surprise researchers with even more benefits.
