Gastroenterologist outlines safe daily tea consumption limits

Dr. Darria Bugomolova, a gastroenterology specialist, said drinking two to four cups of black or green tea a day can lower the risk of cardiovascular disease and cancer. She attributed the benefits to polyphenol compounds that protect cells from free-radical damage and limit the oxidation of LDL cholesterol, adding that the same compounds have antitumor properties by affecting the life cycle of cancer cells. Dr. Bugomolova warned that exceeding the recommended daily intake can raise fluoride and caffeine levels in the body, leading to fluorosis, high blood pressure, anxiety and sleep disorders. The risks increase when consumption exceeds six to eight cups per day, she said. Children should drink no more than one to two cups a day, while pregnant women should limit caffeine intake to 200 milligrams, according to the specialist. High caffeine consumption during pregnancy has been linked to restricted fetal development and low birth weight. Dr. Bugomolova added that herbal teas can serve as a caffeine-free alternative, though their benefits vary by plant and users should be cautious of allergic reactions.
