Dangerous Side Effects of Tea Exposed
Even though previous researches have authenticated about the beneficial aspects of tea, scientists have now pointed out the dangerous side effects it poses.

Scientists have earlier shown that antioxidant properties found in green tea could help prevent coronary artery disease. They had also said that drinking tea could help fight against autoimmune disease - when the immune system attacks itself by mistake.

Some earlier studies have also shown that substances in tea and other foods could help fight cancer.

But in the new study, Rutgers University researchers announced that drinking tea could cause chromosome damage and fetal leukemia, reported the online edition of The Washington Times.

Diet derived compounds are generally regarded as safe, based on their long history of use in the diet or as traditional medicines.

But the phytochemicals, which are compounds in plant-derived foods and found in tea extracts, could have biological activity in the body. It could cause dangerous side effects, said Joshua Lambert, the lead author of the study and a chemist at the university.

His findings reveal that a well-meaning self-remedying public is in danger of overdosing on the compounds, particularly through concentrates and supplements that tout their healing or weight-loss powers, or their lack of caffeine.

One commercial brand of green tea extract, for example, claims to contain more than 700 milligrams of polyphenols, or plant-based antioxidants. A typical cup of green tea provides about 80 milligrams.

Lambert, whose research was funded by the National Institutes of Health, has found an increasing number of human cases of hepatotoxicity, or chemical-induced liver damage, reported in people using tea-based dietary supplements. Research on rats and dogs also found a potential for kidney and intestinal damage.

Though Lambert says further research is needed, some of his findings also suggest that heavy amounts of the compounds could damage human chromosomes, pose harm to pregnant women and increase the risk of leukemia among unborn babies.

He is also concerned about negative interaction between the supplements and common prescriptions or over-the-counter drugs.

About leaf regular Tea I feel, the quantity and concentration is important if it has some effect on anxiety/ gastric. I fully endorse that green tea has to be well tested scientifically. I recently had green tea[plain as well as Tulasi], I suffered with severe gastric problems, it took a day to come down. This could be due to some hypertension related problems. I feel it is important that tea preparations like slim tea, Dr. tea, green tea should be tested by independent Nutritional agencies before they are allowed to market.

Anyone here ever hear of the Asian Paradox? I don't believe this hype for a sec. Green tea has been the most powerful and the healthiest thing you could add to your lifestyle since ancient times. Oh and if there is danger from a supplement, well it is a supplement which is different then a cup of green tea. The article should be more specific about the actual topic being discussed here. If green tea affected medications (which it may) I think there would be a sign of it.


can it really cause leukemia?
i drink about 5 to 10 cups of tea a day

i really dont understand what do scientist to prove, too much brain can cause damage i will not question about their studies about things but as far as i concern as long as i have gain the benefit of dringking tea i continue drinking.


I find these conclusions to be rather outrageous. There are so many more health benefits to drinking tea, which is why it has been practiced in eastern countries for thousands of years. It seems as though sceintists have concluded everything is harmful in our world! I drink on average 3-5 cups a day, and yet I am still living to post this. To hell with phony science! I shall continue to enjoy tea even if it means endangering my future generation.
