I kind of knew that storing food or drink in plastic container was not good. However, I didn't know exactly why. Heidi has a nice blog post about plastic material and their BSA content. The molecular mechanism is very interesting. According to her review, BSA increases MECP2 expression. MECP2 inhibits Kcc2 which code for a chloride pump that is very important to neural development. BSA can leak from plastic container into water or food. An interesting fact that Heidi has in her post is that women are more susceptible to BSA than men.
