Health effects of tea
In clinical research conducted during the early 21st century, the health effects of tea have been widely studied.
Black tea is considered likely effective for improving alertness and possibly effective for certain conditions such as low blood pressure, but evidence does not support its effectiveness for preventing several types of cancer or diabetes; there is currently limited high-quality scientific evidence supporting most specific therapeutic uses of black tea. The United States Food and Drug Administration has approved a topical ointment formulated with a specific green tea extract for the treatment of external genital and perianal warts; although green tea and its extracts have been widely studied, the evidence remains inconclusive overall, with only modest or inconsistent benefits observed.
Two reviews of randomized controlled trials concluded that long-term consumption of black tea slightly lowers systolic and diastolic blood pressures (about 1–2 mmHg), a finding based on limited evidence. A 2013 Cochrane review found some evidence of benefit from tea consumption on cardiovascular markers (total and LDL cholesterol).
In regions without access to safe drinking water, boiling water is effective for reducing waterborne diseases by destroying pathogenic microorganisms, and this water can be used to make tea.
Tea drinking accounts for a high proportion of aluminum in the human diet. The levels are safe, but there has been some concern that aluminum traces may be associated with Alzheimer's disease. A 2013 study additionally indicated that some teas contained lead (mostly Chinese) and aluminum (Indian/Sri Lanka blends, China). There is still insufficient evidence to draw firm conclusions on this subject.
Most studies have found no association between tea intake and iron absorption. However, drinking excessive amounts of black tea may inhibit the absorption of iron, and may harm people with anaemia.
Concerns have been raised about the traditional method of over-boiling tea to produce a decoction, which may increase the amount of environmental contaminants released and consumed.
All tea leaves contain fluoride; however, mature leaves contain as much as 10 to 20 times the fluoride levels of young leaves from the same plant.
