Okay, i got this from the book
Internal cleansing By Linda Berry.
Stanford Uty and Uty of Granada found bisphenol-A in the plastic coatings that manufacvturers use to line metal cans.A high conct was found in canned foods as artichokes,peas,corn.(this stuff is cancer producing)They also found the same stuff in nonsticky pans.Some positive steps that is mentioned are
1.Avoid microwaving food in plastic containers or with microwave plastic wraps.Rehaet in ceramic or glass containers.
2.Avoid overheating plastic juice and water containers(keep them out of hot cars and sunlight).buy juice and water in glass and bottoles.
So i thought this must apply to sippy cups.The very reason i asked.
