Is tea OK for 11 year olds?

Hello there, I'm curious about something. I've heard that tea can be a healthy beverage, packed with antioxidants and other beneficial compounds. However, I'm wondering if it's SAFE for children, specifically 11-year-olds, to consume tea. Are there any potential risks or side effects that I should be aware of? Also, are there any specific types of tea that might be more suitable for children of this age? I'd appreciate any insights you could provide.
