Winter is gently knocking at our doors; with the drop in temperatures, many people drink tea for warmth and coziness. In addition to providing warmth, tea can have several benefits too. Black tea is an all-time favorite as it tastes good and keeps one alert and energized due to the fact that it contains caffeine and a substance called theophylline.Black tea is also full of polyphenols, antioxidants that can help protect your cells from DNA damage, and as a result preventing some types of cancer. Scientific studies have also shown that drinking black tea regularly may lower the risk of diabetes and high cholesterol; it can also help in the prevention of kidney stones and Parkinson’s disease. Early evidence also hints that long-term use of black tea may help protect against osteoporosis, ovarian cancer and mental alertness. However, more studies are underway to further confirm these results.
