Summary – Tea and Adverse effects regarding Caffeine

During the past decade, extensive research on caffeine in relation to cardiovascular disease, fibrocystic breast disease, reproductive function, behavior in children, birth defects, and cancer has identified no significant health hazard from normal caffeine consumption.

The U.S. Food and Drug Administration has conducted research and reviewed the extensive scientific literature on caffeine. In a Federal Register notice published in May 1987, the FDA stated that the agency had reviewed ” studies on teratology, reproduction behavior, carcinogenicity, and cardiovascular disease…but found no evidence to show that the use of caffeine in carbonated beverages would render theses beverages injurious to health.” The American Medical Association has examined the research on caffeine and came to a similarly confident position on its safety. A 1984 report from AMA Council on Scientific Affairs stated, ” Moderate tea or coffee drinkers probably need to have no concern for their health relative to their caffeine consumption provided other lifestyle habits (diet, alcohol consumption) are moderate, as well.”
