Glad you're becoming like me. I limited drinking tea for coffee a long time ago and the reason was the taste of coffee not the health benefits. I also drink tea I don't suggest you leave that either. Keep drinking both because both have their specific good effects on gut health. Tea also comes with full of medicinal properties.
