For about a year, the doubt remains about the dangers of bisphenol A (BPA). This chemical is found in polycarbonate plastic of some rigid and reusable water bottles, baby bottles, plastic utensils, dental sealing epoxy resin and in the coating of food cans.
Research findings in this area seem to say that adults should not worry too much BPA because the amount to which they are exposed is below the toxic standard, although we got closer to becoming.Recently, the federal government ruled that BPA was dangerous substance for people and the environment.
In studies on animals, low doses of BPA detracted from neurological and behavioral development of animals in gestation or newly born. There is also concern that BPA may increase the risk of breast cancer and prostate cancer because of its disruptive effect on the endocrine system. In fact, BPA acts like estrogen in the body. However, according to Health Canada, this causal link is still controversial. Although the federal government admits that bisphenol A is a chemical of concern, it will take at least a year before you have specific recommendations for the use of containers or objects in which we find BPA.
BPA appears to be released into food when the container in which it is found is heated, as when heating food in plastic in the microwave or is added to boiling water in a container plastic. It appears that the migration of BPA in liquid is minimal at room temperature and that one should not be overly concerned.For my part, although unheated plastic with BPA are not a problem, I still prefer to dispose me, because I consider that my body does not need that kind of stuff. Besides, I had two bottles of water sporting to Class 7 and I got rid preventively.
Although products with BPA are not yet banned, several companies have already taken the lead by removing their products with BPA shelves and offering alternatives. We even found bottles emblazoned with the words “BPA free”.
How to know if our bottles or our plastic objects contain BPA? For plastic bottles, find the number 7 in the recycling symbol code. This corresponds to the plastic “Other” in which class polycarbonate, which contains BPA. By cons, some plastic items also contain BPA, but do not bear the logo. If in doubt, contact the manufacturer of the product.
Where to turn to avoid BPA? Personally, I got myself a clear bottle of water in stainless steel from that I bought in Waterbottlesshop. I also am trying to avoid canned foods. When I would fix a tooth, I will ask the dentist not to use material with BPA. I will avoid heat in the microwave, washing in the dishwasher or pour boiling hot liquids in my plastic containers containing bisphenol A.
If you use plastic baby bottles with BPA to feed your baby, you can keep them until further notice as long as you do not add them in contact with heat. However, you can focus on baby bottles made of glass or those made with plastic bearing the code retrieval 1 or 5. If using powdered formula that you dilute in boiled water, avoid boil water in containers with BPA. It is quite possible that Health Canada ban the sale of baby bottles with BPA shortly.
In short, about the effect of chemicals on human health, it is always a question of dosage. Very often, the experts conclude that we consume below the acceptable standard and that there is no need to worry unduly. However, few people wonder about the consequences of the addition and the interaction of many chemicals on human health. In my case, it worries me and I prefer to avoid them as much as possible.
And you, will you wait the official recommendations of Health Canada before changing water bottle for the summer?
