Newcastle University in England looked at green and black tea in a series of laboratory experiments. The results showed that both types of tea inhibited the activity of Enzymes associated with the development of Alzheimer’s disease. In fact, tea appears to affect the brain in a similar way as prescription drugs for Alzheimer’s, however, tea doesn’t have the side effects that the drugs do. According to the scientists, black and green tea fight enzymes that destroy chemical messengers in the brain.
Scientists at Case Western University in Cleveland took two groups of mice and gave them injections of a substance that causes immune reactions similar to those due to rheumatoid arthritis. One group had regular water to drink and the other got water laced with polyphenols, chemicals found in green tea and, to a lessar extent black tea. Nearly all the mice that drank regular water got arthritis-like symptoms, compared to less than half of the treated mice. Green tea and its polyphenols are great for controlling arthritis, it has an antioxidant called EGCG that blocks enzymes from breaking down cartilage.
Tea flavonoids may be bone builders and fight Osteoporosis. A report in the archives of internal Medicine looked at about 500 chinese men and women who regularly drank black, green, or oolong tea for more than 10 years. Compared with non-habitual tea drinkers, tea regulars had higher bone mineral densities, even after exercise and calcium were taken into account. A British University study found that drinking one cup a day was linked to a 5% higher bone mineral density in senior citizens. A new study in the American Journal of Clinical Nutrition found that green tea drinkers had bones that were 3% thicker than non-tea drinkers
Coffee can give you bad breath, but polyphenols found in both black and green tea can stop the growth of bacteria that cause bad breath. Black tea also suppresses the growth of bacteria in dental plaque and rinsing with black tea reduces plaque formation and the production of acids that cause tooth decay. Japanese researchers also found that green tea helped patients with gingivitis and more advanced gum disease.
“Tea is one of the single best cancer fighters you can put in your body,” according to Dr. Mitchell Gaynor, director of medical oncology at the world-renowned Strong Cancer Prevention Center in New York CIty. Studies have shown that both green and black teas kept healthy cells from turning malignant after exposure to cancer-causing compounds. John Hopkins University studies showed that drinking 2 to 3 cups of tea daily reduced the risk of developing urinary tract cancer by 60%, and digestive tract cancer by 32%.
New research confirms that extracts of black tea can help reduce cholesterol. Researchers at Vanderbilt University tested 240 people with mild to moderately high cholesterol who were on a low-fat diet. Half took a daily black tea extract with polyphenols (equal to 7 cups of tea); the other half took a placebo. After 12 weeks, those on tea cut their LDL by 16%. “Over time that could translate into a 16 to 24% reduction in risk of heart attack and stroke” says Dr. David Maron, MD, cardiologist and lead researcher.
