If you are a fan of protein shakes and you drink them on a regular basis, do you know exactly what type of shaker you are using? Many plastic bottles contain the chemical BPA which can be very dangerous for your health.
What is BPA?
Bisphenol, known as BPA, is a synthetic chemical that is commonly used in plastics (clear and tinted) that are used to make food containers and water bottles. BPA is used as it is cheap and very lightweight which means that its use is very widespread. While popular, research has shown that BPA can cause harm and in 2012 it was banned from baby products such as milk bottles and sippy cups by the FDA. As BPA can leak into food and is also dust and air born, it is recommended that BPA free products are used.
How BPA Damages the Body
The chemicals in BPA are thought to be toxic and, while scientists still investigate, it is believed that BPA has a negative effect on our brain and development. BPA contains xenoestrogen which is thought to have an effect on everything from early onset puberty, infertility, heart disease and breast cancer. While you cannot directly ingest BPA, the chemical is slowly released into the contents of the container and is especially prevalent in old and damaged bottles made of BPA.
Understanding Your Plastics
All plastic containers, whether they be food packaging, microwaveable bowls or protein shaker bottles must have the recycled symbol at the bottom. The recycling codes alongside the symbol contain codes that indicate what plastic is used in the product. Code “3” is used for Polyvinyl Chloride (PVC) plastic which contains phthalates, which should always be avoided where possible. If the bottom of the container has the number 2 and the letters HDPE (high-density polyethylene), number 4 LDPE (low-density polyethylene), or a number 5 PP (polypropylene) they are very safe to use. A plastic container without a recycling symbol should not be trusted as should any containers that show signs of wear and tear. Any damage to plastic containers runs the risk of leaking toxins into your food which can make you very ill.
The Best Protein Shaker Bottles
There are many premium protein shaker bottles on the market that are completely BPA free. Premium brands such as SmartShake, Perfect Shaker and Cyclone Cup use high-quality plastic that gives the shake enthusiast the peace of mind that they need when it comes to their health. Similarly, premium protein shaker bottles that have a metal finish will be of the surgical grade and will cause you no harm. You may be tempted to use an old plastic bottle but if you are drinking shakes on a regular basis then you can slowly be doing more harm to your body than you think.
While premium BPA free protein shaker bottles will cost a little bit more than a plastic bottle containing BPA it is a wise investment as your health should be of paramount importance.
