Plastics, so convenient, so ubiquitous, so problematic. While it's probably impossible to eliminate plastics from your life entirely, you can and should try to keep them out of your food. Harmful plastic chemicals such as BPA and phthalates are in our bodies, and researchers believe they most commonly enter our bodies through ingestion via our mouths. But it's not enough to avoid BPA or other specific plastic chemicals. The absence of an effective toxic chemical policy framework means that toxic plastic chemicals (such as BPA) are often replaced with another untested chemical (BPS), which all too often is later found to be just as problematic (the so-called "toxic treadmill"). The issue is the undisclosed additives. As plastic-free living guru Beth Terry explained in an interview:
The issue is, it is impossible to know if any plastic is safe. In addition to the problems we know about, plastics can contain thousands of possible additives to affect the hardness, or softness, or slippery-ness, and manufacturers don’t disclose what their recipes are. The number on the container tells you what type of plastic it is, but it doesn’t tell you what else has been added to the plastic. If you don’t know what’s in it, you can’t tell what will leach out of it. The additives are not bound to the polymer, and when the plastic is subject to stress (light, heat) it can leach. (source)As a 2011 study famously demonstrated, almost all commercially available plastics leach endocrine disruptors when subjected to common-use stresses, such as microwaving or the humid heat of the dishwasher. Recent studies have connected plastic chemicals to autistic behaviors, reduced sperm count, irregular heartbeats, and higher blood pressure. In fact, researchers recently concluded that "there is a greater than 99 percent chance that endocrine-disrupting chemicals [including BPA and phthalates, found in plastics] are contributing" to neurological effects (such as attention problems), obesity and diabetes, as well as infertility and other male reproductive disorders.
When trying to keep plastic out of your diet, keep in mind the following:
- Children are more susceptible to health problems caused by plastic chemicals due to the fact that they consume a greater amount of food relative to their body weight and because of their rapid pace of development. The safety of children's dishware and foods should be top priorities. Because fetuses are also particularly vulnerable, pregnant women too should take particular care to avoid eating plastic.
- Fat, salt, acid, heat, UV light all promote the leaching of plastic chemicals into food. This is why if you leave your plastic water bottle in your car on a hot day, your water tastes "plasticky." It is also why canned foods that are acidic (pasta sauce), fatty (coconut milk) or salty (soup) contain higher levels of BPA. Naturally, plastic chemicals more readily migrate into liquid foods as well. This is why I pay special attention to how high fat, salty, acidic, and liquid food products are packaged.
- Styrofoam, PVC/ vinyl, PFCs (such as Teflon), and hard clear plastics (originally made with BPA and now the no-better BPS) are especially to be avoided. While all plastics are suspect due to undisclosed ingredients, these plastics are widely accepted to be harmful to human health.
instead. Several small parts that attach the nipple to the glass bottom (valve, ring) are plastic, but the bottle is mostly glass. The nipple, like most bottle nipples, is silicone. We like the 
, but stored and reheated the milk only in glass, and hand washed the plastic bottles. It's really tough to get around plastic when you bottle feed.
