Hi, no this is not a good practice as tea is a caffine and caffine hinders the absorbtion of foods that you eat.What you can do is have your banana as the first thing in the morning then after an hour you can have your tea as any fruit takes exactly 45 minutes to one hour to get digested.So enjoy having both food items but by giving a gap of one hour atleast.
Next Steps
