We all know plastic is bad for the environment and hopefully you've stopped microwaving in it...anyone old enough to remember what we used to use before plastic was invented?
1) Refrigerator glass storage containers with heavy lids that either locked on with a rubber washer lid or fit squarely on top....came in squares or in order to stack nicely in the fridge.
2)***Waxed paper, in both sheets and bags.
3) Of course there's the ubiquitous tin or metal lunch box.
Did you know water sitting in a plastic bottle can leach plastic residues into the water? To be certain that you are choosing a bottle that does not leach, check the recycling symbol on your bottle. If it is a #2 HDPE (high density polyethylene), or a #4 LDPE (low density polyethylene), or a #5 PP (polypropylene), your bottle is fine. The type of plastic bottle in which water is usually sold is usually a #1, and is only recommended for one time use. Do not refill it. Better to use a reusable water bottle, and fill it with your own filtered water from home and keep these single-use bottles out of the landfill.
Unfortunately, those fabulous colourful hard plastic lexan bottles made with polycarbonate plastics and identified by the #7 recycling symbol, may leach BPA. Bisphenol A is a xenoestrogen, a known endocrine disruptor, meaning it disturbs the hormonal messaging in our bodies. Synthetic xenoestrogens are linked to breast cancer and uterine cancer in women, decreased testosterone levels in men, and are particularly devastating to babies and young children. BPA has even been linked to insulin resistance and Type 2 Diabetes. For more of the science on the effects of BPA on our endocrine system etc. see these studies: Environmental Health Perspectives Journal
. Nalgene, the company that manufactures the lexan water bottles also makes #2 HDPE bottles in the same sizes and shapes, so we have a viable alternative. Order one at Nalgene
Welcome to the board, please don't worry too much but you may also want to switch from drinking bottled water in plastic and especially if the water has sat in a plastic bottle for a long time in a hot environment. We had a lot of press about BPA, still do here in the US, not sure what the laws are in the UK. Be good to yourself and your environment, stop using plastic bottles.
