Can iced tea be consumed?
Generally speaking, it is safe to drink tea cold.
When tea cools down but has only been left for a short period of time, it can still be consumed. The composition of the tea remains unchanged and will not negatively affect health, so drinking cold tea is acceptable. However, if tea has been left out for too long, large amounts of microorganisms may grow on its surface, making it unsafe to drink. Consuming such tea could irritate the digestive system and be detrimental to health.
Tea contains certain amounts of tea polyphenols, which help regulate the body's fat metabolism and may help prevent cardiovascular and cerebrovascular diseases. It also contains abundant caffeine, which stimulates the stomach to secrete more gastric acid, thereby promoting digestion and aiding the digestive system. Additionally, tea contains vitamin E, which helps eliminate free radicals in the body and maintain cellular activity, contributing to anti-aging effects. However, since tea also contains caffeine, excessive consumption may irritate the gastrointestinal tract. Therefore, it is important not to drink too much tea.
