With tea against cancer
In Japan and conducted over 11-year so-called Ohsaki study of 40 530 adults aged 40-79 years found that the drink has positive cardiovascular properties thereby prolong life works. Accordingly, the mortality rates of male Test participants who drank at least five cups a day, up 12 percent, in women by 23 percent. Especially because of deaths Cardiovascular diseases were rare, even more clearly here in women (31/22 percent). Reducing the mortality from cancer was not detected in this study. Some other studies provide evidence that the regular consumption of green tea is the risk of cancer disease, may diminish as in parts of the world where a lot of tea is drunk, the incidence of certain cancers is lower than in the rest of the world. For a preventative In particular, the effect naturally in many types of tea polyphenols (particularly the epigallocatechin gallate, EGCG) is responsible made. A study of patients with prostate cancer, which was conducted at the Center for Human Nutrition at the David Geffen School of Medicine, UCLA was able to show that the native of the tea EGCG was detected in the tumors and inhibited cell growth. The results suggest that green tea and black tea can help to prevent prostate cancer.
In particular, black tea and green tea polyphenols and fluorides reduce the risk to Zahnkaries.Durch the addition of milk is calcium oxalate as a sparingly soluble salt. The risk of renal stone formation is reduced. However, the milk binds the force to be valuable polyphenols.
Who more than ten cups of green tea a day could drink, to damage his liver and kidneys. This claim Chung Yang and his colleagues at Rutgers University in New Jersey in the journal Chemical Research in Toxicology "after a screening of studies. Excessively high doses of the polyphenols in green tea may be toxic, says Yang. So far, this hypothesis in studies on humans could not be confirmed.
In another Japanese study has shown that show both green tea and red bush tea (rooibos tea) a prophylactic effect against diabetic nephropathy. It is believed that the polyphenols in green tea, red bush, or the information contained in flavonoids, free radical trap. This may be the addition of glucose to the body's own proteins (the so-called Maillard reaction) is reduced, whereby the kidney is protected effectively. Diabetic nephropathy is caused by diabetes mellitus, a kidney disease. She is a frequent cause of kidney failure in diabetics.
Huntington's disease is an inherited, neuro-degenerative disease. In model organisms, it was found that green tea can delay the disease leading to plaque formation. Responsibility is extracted from green tea compound EGCG. She is able to delay a clumping of the protein called Huntington. Transgenic flies, where the Huntington's gene has been transferred, also showed improved mobility after ingestion of EGCG.
The Egyptian scientist Dr. Mervat Kassem found that antibiotics appear much better if the patients also drink green tea. His research team tested the effect of this combination to the pathogens of infectious diseases 28. The green tea enhanced the effect in all cases. Even some bacteria that no longer responded to antibiotics, were again attacked.
Neurodegenerative diseases like Alzheimer's and Parkinson's diseases are caused by the formation of amyloid. The substance contained in green tea EGCG prevents the formation through binding to the native, still unfolded polypeptide chains. Thus, instead of the toxic, fibrous amyloid fibrils harmless, spherical oligomers are formed.
