Tea helps reduce the risk of death from various causes, including cardiovascular diseases and cancer.
Oxu.Az reports that this information was published by Gazeta.ru based on a statement by gastroenterologist Darya Bogomolova.
The recommended daily consumption of black or green tea for adults is 2-4 cups.
Natural compounds called polyphenols in tea have high antioxidant effects. These substances protect human cells from the negative effects of free radicals, minimizing the likelihood of chronic diseases. At the same time, polyphenols prevent the oxidation of "bad" cholesterol, which significantly reduces the risk of cardiovascular diseases and atherosclerosis. Experts note that these natural compounds can exhibit anti-oncological properties by hindering the development of cancer cells.
The doctor reminded that excessive tea consumption can lead to negative health consequences:
Fluoride accumulation: Regular intake of tea above the norm leads to the ingestion of large amounts of fluoride. This can cause fluorosis (damage to teeth and bone tissue), especially in regions with high fluoride levels in water sources.
Caffeine intake: Each cup of tea contains an average of 30-50 mg of caffeine. Consuming more than 400 mg (about 6-8 cups) can increase blood pressure, accelerate heart rate, and cause anxiety, insomnia, and excessive alertness.
To avoid the negative effects of caffeine, children are advised not to drink more than 1-2 cups of tea per day. Pregnant women should monitor their total caffeine intake, as excess can cause fetal growth retardation and an increased risk of low birth weight. The safe limit for pregnant women is up to 200 mg of caffeine per day.
"Herbal teas are infusions of various plants that differ in composition and effect. Unlike black and green tea, most of them do not contain caffeine. Therefore, they can be an alternative for those who need to limit caffeine. It should be emphasized that the effects and safety of herbal teas depend on the specific plant. To avoid negative outcomes, it is important to consider individual intolerances or allergies when choosing a herbal tea," the expert noted.
