Plastics: Which Ones To Avoid, And Why
You’re likely aware that plastics are harmful to your health. They have phenomenally long half-lives, and don’t break down in the body, causing ongoing damage.Look on the bottom of your bottle, and see the number in the little triangle. Look carefully at this graphic, because the numbers aren’t consecutive. The worst grades of plastic are 6, 3, and 7.
A 7 is the worst grade of plastic, and most labeled 7 contain the most infamous chemical in plastics: Bisphenol A (BPA).
Water and other liquids leach BPA. This endocrine-disruptor chemical can do crazy things to your hormones. The U.S. finally banned the chemical in baby bottles, after the European Union and Canada did. Wiki says a study found BPA in 96% of pregnant women. It’s been linked to obesity, breast and prostate cancer, and ADHD.
Please don’t use old baby bottles or any other plastic that isn’t BPA free that comes into contact with your food or water. More and more companies are making their plastics without BPA, including Blendtec’s blender jars. But our FDA continues to support the use of BPA in cans, including drinks, and infant formula!
Another chemical to avoid is PVC (polyvinyl chloride), known as vinyl, which contains phthalates, known to cause birth defects in baby boys, testicular cancer, infertility, and asthma. PVC plastics are labeled with the 3 triangle.
So, anything you use that’s plastic, make sure it’s labeled 1, 2, 4, or 5.
Our GreenSmoothieGirl bottles, of course, are BPA free, vinyl free, and phthalate free.
