Loose Leaf Tea Health Benefits
Though they may not be magic elixirs, the hard data on the benefit of loose teas—black, green and white--developed and published by medical organizations, research institutes and laboratories, certainly suggests that the consumption of these products may indeed have wide-ranging medical benefits.
In recent years a number of major clinical and laboratory studies in the United States and abroad have shown that tea consumption—especially of loose teas—has significant benefit to the health of prostate glands, bones, skin, teeth and gums, hearts, help block allergic responses, boost metabolisms and aid in weight loss, delay the onset of diabetes and protect against Parkinson’s Disease—the list goes on and on. For example . . .
Health Benfits Seen In Studies
In a recent California study reported in the Journal of Nutrition, researchers found the presence of tea polyphenols and theaflavins in the prostate glands of test subjects who ingested black and green teas, and noted that cancer cell proliferation was less when samples were grown in media with serum taken from these subjects. Papers presented at the American Institute for Cancer Research/WCRF International Research Conference on Food, Nutrition and Cancer (July, 2005), established new evidence of links between green tea compounds and cancer prevention that include: diffusing cancer-causing proteins found throughout the body; preventing prostate cell proliferation; slowing the growth of breast tumors; and causing cell death in lymphoma cells.
A study conducted in China and reported on in the International Journal of Cancer found that consumption of green tea was associated with a 41 percent reduction in risk for stomach cancer. University of Arizona researchers found that smokers who drank four cups of green tea daily for four months showed a marked decrease in cell damage caused by smoking. The National Cancer Institute found in animal tests that catechins in green tea deactivated oxidants before cell damage could occur, inhibited cancer cell growth and reduced the size and number of tumors. The American Journal of Clinical Nutrition also reported that seniors in Japan who drank one or more cups of green tea per day were significantly less likely than those who drank less tea to show cognitive and memory problems.
Black Tea Health Benefits
Black tea consumption was shown to provide benefit to teeth and gums in a recent Chicago College of Dentistry study. Subjects who rinsed with black tea multiple times daily were shown to have reduced plaque build-up compared to those who rinsed with water. At the Harvard Medical School a study of 340 people who had suffered from heart attacks found that those who drank at least one cup of black tea per day reduced their chance of repeated heart attacks by 44 percent, when compared to non-tea drinkers. A Boston University study indicated that black tea drinking helps prevent narrowed or clogged arteries that lead to heart disease or stroke.
White Tea Health Benefits
White teas too have been shown to provide significant health benefits. Made from immature tea leaves and undergoing less processing than black or green teas, white tea contain more polyphenols, the cancer-fighting antioxidant, than other teas. At Pace University research has shown that white tea extract may help retard the growth of bacteria that cause staphylococcus infections, pneumonia and dental cavities. Researchers say that white tea may actually destroy the disease-causing organisms, while green tea only stimulates the immune system to fight disease.
Scientists also say that compounds in white tea are effective in enhancing skin cells’ immune functions and protecting the skin from harmful effects of the sun. Elma Barton, the Director of the Skin Study Center at University Hospitals of Cleveland and Case Western Reserve University reported that “We found the application of white tea extract protects critical elements of the skin's immune system. Similar to the way oxidation causes a car to rust, oxidative stress of the skin causes a breakdown in cellular strength and function. The white tea extract protects against this stress. This study further demonstrates the importance of researching how plant products can actually protect the skin."
The evidence is compelling. From formal studies to anecdotal reports, the facts do more than just suggest that loose black, green and white teas offer significant medical benefits and can offer relief and protection from a host of ailments.
