Bisphenol A, or BPA, is a component found in some types of plastic, including food & drink containers, baby bottles, children's toys & the lining of some canned food. Research has shown that BPA can leech from the plastic into whatever it comes into contact with, especially under heat.
The issue with BPA is that it's a known endocrine disruptor - meaning it has the ability to imitate our bodies hormones and interfere with the production of, or response to, or action of, our bodies natural hormones. Whilst many of the studies have been on animals, BPA is thought to mimic our hormone oestrogen, and has been shown to affect egg maturation, the function of the hypothalamus & pituitary glands, Type 2 Diabetes, obesity, precocious puberty, metabolic syndrome, early menopause, foetal brain development, heart disease ... the list goes on! So what about BPA free plastics? Scientists are suggesting that compounds in the BPA-free plastic, such as BPS, BPF & BPAF may be just as damaging to our health. The reality is, the BPA-free alternatives are not very different to BPA itself - they have the same basic chemical structure, with only slight differences from BPA, so it is likely that BPA-free plastics are not safe, either. The statistics are pretty frightening when you look into how widespread our consumption of BPA is. A 2009 CDC study found 10 types of cancer-causing plastic additives in 92% of urine samples taken from 2,517 children aged six years and older.
Aaaaaaahhhh, so what can we do? We need to avoid plastics, wherever we can. First up, don't heat or serve food in plastic. Buy dried beans over tinned, & tomato passata in glass. Use stainless steel or glass drink & lunch containers & reusable beeswax or silicone wraps instead of plastic cling film. Some of these changes are expensive & daunting; start small, & keep going where you can. Ultimately, it's better for our health, and our environment.
