BPA And Water Bottles

BPA And Water Bottles, Concern about the controversial chemical BPA (bisphenol A) caused an increase in water bottles and metal products labeled “BPA free”. Studies have linked the chemical to the problems with the brain and nervous system, behavior and reproductive problems and some cancers. BPA is a chemical widely used in food packaging, hard plastics and metal can coatings.
Researchers at the University of Cincinnati wanted to know if the bottles marketed as alternatives to plastics that contain BPA really live up to its claim. The process proved to stainless steel bottles and aluminum water has become a popular alternative to plastic because of concern about BPA. The researchers found some aluminum bottles release up to five times the amount of BPA that some plastic bottles. Leaching of the chemical bottles lined epoxy-based resins. The researchers found two stainless steel and polyester coated bottles do not leach BPA. Experts say that epoxy coatings are usually copper-colored and may be sticky to the touch. UC professor Scott Belcher said: “Consumers should not think that just because a polycarbonate plastic bottle that is not safe from the dangers of BPA.”
The study showed that when the bottles are used according to manufacturer’s recommendations and are built with BPA-free alternative materials that could be used without fear of contamination BPA. The researchers also say that the bottles tested with “BPA-free” labels do not filter out chemicals. However, experts point out that “BPA-free” label is not regulated and has no real meaning other than a marketing label.
Other packages and products containing BPA and simple steps you can take to avoid exposure.
1. Knowing what type of plastic you are buying
If using plastic containers for food or buying food in a plastic, see bottom. The BPA used in polycarbonate containers often marked with the recycling label No. 7. Plastics with recycling numbers # 1, # 2 and # 4 are safer options.
2. Use powdered formula and bottles without BPA
BPA can leach into liquid formula sold in metal cans. Powdered formula has been shown that BPA-free so that is the best option. Most manufacturers now offer BPA-free baby bottles made, but as a rule, hard plastic, clear, while often containing BPA soft plastic, usually not clear. Avoid bottles marked on the bottom with “PC” for polycarbonate or the number 7.
3. Decrease in canned foods
BPA is also found in the lining of canned foods and juices. The chemical can actually leak from the coating in the food itself. BPA has even been found in products labeled “without BPA.” The evidence also shows that the drinks generally contain the lowest amount of BPA, while the pasta and soups contain the highest. Also, canned foods with high levels of acidity, like tomatoes generally have high levels of BPA. Experts recommend rinsing fruit and vegetables with water to remove any chemical residue.
4) A careful how to handle the receipts
Several studies have found BPA in thermal paper receipts including cash. If you do not need the receipt, ask the cashier to quit or not a print. If you need it, be sure to wash hands after handling. Certainly, never let your children handle store receipts.
5) Use glass containers for heating food in microwave
There is evidence that BPA can leach into food when heated in plastic containers in the microwave, even those who have been labeled as “microwave.” To reduce potential exposure to heat your meal in a glass or ceramic.
