Even BPA-free products can leach different chemicals capable of disrupting hormones within the human body.
Exposure to Bisphenol A, otherwise known as BPA, is widespread. The 2004 National Health and Nutrition Examination Survey found that 93% of participants tested positive for this chemical, which is commonly used to make hard plastics and resins. Why should we be concerned about this?
BPA is found everywhere in our normal surroundings, making it quite difficult to avoid exposure. Common sources are water bottles, canned foods, and thermal-printed store receipts. Due to industrial activity it is also emitted into the atmosphere, consequentially contaminating ground water and food. This directly impacts consumers because synthetic xenoestrogens are capable of disrupting the normal function of various hormones within the body.
To address increasing concern, the food and beverage industry has started to promote BPA-free canned foods as well as bottles. However, based on a 2014 hazard assessment survey published in Environmental Health, many BPA-free products continue to leach different xenobiotic chemicals also capable of disrupting hormones within the human body.
