From a Winston Kao newletter.
Industry produces billions of pounds of plastic per year, and it is used in virtually every category of goods sold or used. One big problem with plastic is that when used for storing or transporting food and drink, some plastic nanoparticles are shed, to be later consumed by people.
Furthermore, plastic which ends up in waste streams breaks down over time, into smaller and smaller particles which end up in plants and animals and, eventually, people.
Recent research by the University of New Mexico discovered that the arteries of people affected by strokes and heart attacks contain about 50 times more plastic than the arteries in healthy people. While this by itself does not prove that plastics cause artery disease, it does suggest that we should minimize our exposures to plastics where possible.
Avoid cooking or storing food in plastic containers. Use glass or stainless steel instead.
Purchase food and drink not packaged in plastic. Whole foods such as fresh produce should be a considerable part of your diet. Purchase beverages in glass containers, avoiding plastics where possible.
Never heat food in plastic trays, as is often done with microwave ovens, as this can release plastic into the food. (I strongly urge you not to use microwave ovens at all, as they damage the chemical structure and reduce the nutritional value of foods.)
Filter your water at home with a high-quality filter which is NOT reverse osmosis (RO). RO filters actually shed plastic nanoparticles into the water (about a quarter million particles per liter).
