Effects: Black tea is a source of caffeine, a methylxanthine that stimulates the central nervous system, relaxes smooth muscle in the airways to the lungs (bronchioles), stimulates the heart, and acts on the kidney as a diuretic (increasing urine). One cup of tea contains about 50 milligrams of caffeine, depending on the strength and size of cup (as compared to coffee, which contains 65 to 175 milligrams of caffeine per cup). Tea also contains polyphenols (catechins, anthocyanins, phenolic acids), tannin, trace elements, and vitamins.
A study by Drs. Rumpler, Seale, Clevidence, Yamamoto and Komatsu of the U.S.D.A. Beltsville Humer Nutrition Center proved that there is a link between drinking tea and weight loss. Persistent consumption of tea is required, they reported, to obtain any beneficial effect. A study in Japan published in the "Annals of Nutrition and Metabolism" in 2008 showed that black tea helped with weight loss, and also had the additional benefit of lowering cholesterol levels. Tea can accelerate weight loss by boosting the body's metabolism. At the same time, it also blocks the fattening effects of carbohydrates. This is especially true of Oolong tea. Both black tea and Oolong tea are derived from the same plant, Camellia sinensis. With black tea, the leaves are left to oxidize after they are picked. With Oolong tea, the leaves are wilted in the sun and then "bruised" to expose the juice to the air, where partial oxidation is allowed to take place before being fully dried. One particular ingredient has not yet been identified with black tea's ability to aid in weight loss. Patients have lost weight when black tea consumption was used in combination with other nutritional supplements. It is not yet understood exactly how black tea alone, or in what specific combination with other supplements, gives it the ability to help with weight loss, but there is ample evidence for its benefit. Tea contains caffeine, catechins, polyphenols, flavonoids and amino acids. These ingredients are known to have effects on neurotransmitters in the brain.
