Bisphenol A (BPA) belongs to a group of chemicals called ‘xenoestrogens’, which are used to make pesticides, herbicides and plastics. Xenoestrogens act like oestrogen in the body, attaching themselves to oestrogen-receptors, in both males and females. These artificial oestrogens can interfere with normal hormonal signaling.
We should take measures to avoid these ‘hormone-mimicking’ chemicals as they may increase the risk of breast, prostate, and reproductive cancers; reduce fertility and immune function; cause early puberty in children; menstrual irregularities and other disorders
Of all the xenoestrogens, BPA has the greatest impact on our health. BPA is used to make hard, clear plastic containers (baby bottles, water bottles, microwave ovenware, eating utensils, milk and juice containers) and plastic coating inside metal cans
The best way to reduce your contact with xenoestrogens
buy and store foods and beverages in glass or stainless steel containers. Avoid plastic food containers and bottles with recycling label No. 7 or letters ‘PC’ on the bottom, as they contain BPA’s. Trace amounts of BPA can leach from these containers into foods and drink. Plastics with the recycling label 1, 2 and 4 are a better choice as they are BPA-free.
Do not to heat food in a plastic containers or plastic cling wrap, since heating some plastics can cause xenoestrogens to leach out of the container into the food. Some plastic cling wrap is made from PVC (polyvinyl chloride), and contain xenoestrogens
