BPA (bisphenol A)
So what does BPA free mean and is it harmful to our health?
BPA is a common chemical. It is mainly used in combination with other chemicals in the manufacture of plastics and resins.
BPA can leach into food from the coatings of canned foods and from consumer products such as tableware, food storage containers, water bottles, and baby bottles. The amount of BPA that leaches into our food depends on the heat in which the plastic reaches. BPA can be found in small quantities in the urine of most adults and can also be found in breast milk!
BPA may mimic hormones and interfere with the endocrine system of glands, which release hormones around the body. Some scientists think that if it interferes with sex hormones, this could affect puberty or the menopause or cause cancers that are related to hormones.
Those calling for a ban suggest that it may be a factor in a rising numbers of human illnesses, such as breast cancer, heart disease and genital birth defects.
In January 2010, the US Food and Drug Administration, which is responsible for protecting and promoting Americans’ health through regulation and supervision of food safety, expressed concern over the impact of BPA on the brains and development of young children. It said it was “taking reasonable steps to reduce human exposure” to BPA in the food supply. Canada and some American states have banned the use of BPA in baby feeding bottles.
Animal studies on the effects of BPA so far have suggested that infants and children are the most vulnerable.
What can we do to limit exposure?
• Do not microwave plastic food containers. Especially if you are not sure that they are BPA free.
• Some containers have recycle codes on them, Plastics that are marked with a 3 or 7 may be made with BPA.
• When possible choose glass containers, porcelain or stainless steel.
• Use baby bottles that are BPA free. Use BPA free Dummy/soothers.
• Reduce the use of canned foods. Especially those that you know have white protective lining.
