Same thing came in my mind when my doctor advised me to eat pineapples with core …trust me my reaction was almost as like you 😀😁but then she smiled and simply said to me oh my dear please do some research if you have any doubt about anything, pineapple’s core is the most important part of it that we all need too eat …. So same thing I would say to you that please do google about it 😊🙏🏼🙏🏼
