Most babies are fed using feeding bottles. A plastic called polycarbonate is used to make feeding bottles because it is strong, durable and heat resistant to an extent. It can be sterilized easily and would not soak up odours. When it was first introduced, it was commonly accepted as a suitable substitute for glass and ceramic. Polycarbonate is preferred for making the inner linings of food containers and reusable plastic bottles as well.
Though polycarbonate is a preferred material, it is not essentially safe. A harmful substance known as bisphenol-A leaches out of the polymer and gets mixed with food. This chemical can cause health issues. It changes the level of oestrogen in our bodies.
