Many plastic containers contain harmful chemicals that may include, but are not limited to, phthalate, bisphenol A (commonly known as BPA), styrene, PVC, and dioxin. These chemicals have been linked to cancer.
"The disturbing truth is that heat transfers the chemicals in plastic very effectively into your food. When the food is heated, the food touching the plastic receives the chemicals leaching out. Eating those chemicals can increase risks of cancer, infertility and havoc on the normal functioning of reproductive systems and your brain[.]" - Quote by Dr Nitasha Gupta, an IVF expert
