Because health tea is a field with ongoing research, IELTS loves Not Given. If the passage says “Chamomile may reduce anxiety,” but the question says “Chamomile eliminates anxiety,” the answer is False, not Not Given. Only choose Not Given if the concept (e.g., “side effects on children”) is entirely absent from the text.
Paragraph A Tea, derived from the Camellia sinensis plant, is second only to water as the most consumed beverage in the world. While water is essential for hydration, tea offers a complex profile of compounds that have intrigued medical researchers for decades. Historically, tea has been used in traditional medicine to treat ailments ranging from headaches to depression. Modern science has now begun to validate many of these ancient claims, categorizing tea not just as a beverage, but as a functional food capable of preventing chronic diseases.
Paragraph B The primary bioactive agents in tea are polyphenols, specifically flavonoids, which act as powerful antioxidants. These compounds neutralize free radicals—unstable molecules that can damage cells and contribute to aging and diseases like cancer. Green tea, which undergoes minimal processing, retains a high concentration of a specific flavonoid called epigallocatechin gallate (EGCG). In contrast, black tea is fully fermented, converting these flavonoids into theaflavins and thearubigins. While the chemical structures differ, both green and black teas have demonstrated significant antioxidant activity in clinical trials.
Paragraph C One of the most publicized benefits of tea consumption is its potential to improve cardiovascular health. A longitudinal study conducted over ten years found that individuals who drank at least three cups of green tea daily had a significantly lower risk of stroke and heart attack compared to non-tea drinkers. Researchers attribute this to the ability of tea polyphenols to improve endothelial function (the health of the inner lining of blood vessels) and reduce levels of LDL cholesterol, often referred to as "bad" cholesterol.
Paragraph D However, the health benefits of tea are not without contention. Some nutritionists argue that the "health tea" market has been diluted by ready-to-drink bottled teas, which often contain excessive amounts of added sugar. Furthermore, the bioavailability of tea compounds—the degree to which they are absorbed by the body—can be inhibited by the addition of milk. Proteins in milk, specifically caseins, can bind with flavonoids, potentially reducing their antioxidant efficacy. Consequently, while a freshly brewed cup of tea is widely regarded as beneficial, the same cannot be said for highly processed tea beverages or those heavily diluted with dairy. health tea ielts reading answers
Paragraph E Another area of interest is the relationship between tea and mental acuity. Tea contains L-theanine, an amino acid that can cross the blood-brain barrier. Unlike coffee, which provides a rapid caffeine "jolt" followed by a crash, the combination of caffeine and L-theanine in tea promotes a state of "alert relaxation." Studies suggest this synergistic effect improves attention span and memory recall without the jittery side effects associated with other caffeinated beverages.

Reading Passage
A. Tea is the second most consumed beverage in the world, surpassed only by water. While it has been a staple of social life and culture for centuries, modern science is now unraveling the specific chemical properties that make tea a potent tool for preventative health. From the fermented leaves of black tea to the unfermented shoots of green tea, the Camellia sinensis plant offers a spectrum of benefits that researchers are only beginning to fully understand.

B. The primary distinction between the main varieties of tea—green, black, white, and oolong—lies in the processing method. All tea comes from the same plant, but the level of oxidation determines the chemical profile. Green tea is unoxidized; the leaves are heated immediately after picking to preserve the polyphenols. Black tea, conversely, is fully oxidized, which changes the chemical composition, converting simple polyphenols into more complex compounds known as theaflavins. While both types offer health benefits, the preservation of catechins in green tea has drawn significant attention in medical research.
C. The most celebrated compound in green tea is Epigallocatechin gallate, commonly referred to as EGCG. This powerful antioxidant has been the subject of hundreds of studies. Research published in the Journal of Nutrition suggests that EGCG can inhibit the growth of cancer cells without damaging healthy tissue. Furthermore, it appears to improve the function of the endothelial cells lining the blood vessels, which can reduce the risk of cardiovascular disease. However, nutritionists warn that adding milk to tea may bind with these polyphenols, potentially reducing their absorption rate in the body.
D. Beyond heart health and cancer prevention, tea has shown promise in the battle against obesity. A study conducted by the University of Geneva found that men given a green tea extract burned more calories than those given a placebo or caffeine alone. This thermogenic effect is not solely due to the caffeine content but rather the interaction between caffeine and the polyphenols found in the tea. This suggests that tea could be a valuable adjunct to a weight loss regimen, though experts maintain it is not a magic bullet for shedding pounds.
E. However, the health narrative surrounding tea is not without its caveats. Excessive consumption can lead to negative side effects due to the presence of tannins and caffeine. Tannins can interfere with the absorption of iron from plant sources, posing a risk for individuals suffering from anemia. Additionally, herbal infusions, often grouped under the umbrella of "tea," are not derived from Camellia sinensis and have vastly different chemical properties. For instance, chamomile is prized for its sedative effects, acting as a sleep aid, whereas yerba mate is highly caffeinated and used for stimulation.
F. Despite the marketing hype surrounding detox teas and weight-loss blends, the most significant benefit of tea may be its simplest one: hydration. For years, it was believed that the caffeine in tea acted as a diuretic, negating its hydrating properties. However, recent studies indicate that the diuretic effect of moderate tea consumption is negligible. Therefore, tea contributes to daily fluid intake, promoting kidney function and overall homeostasis. As research continues, the consensus remains that moderate tea consumption is a healthy habit, offering a moment of calm and a boost to long-term well-being.
