On the bottom of my water bottle there is a number inside a triangle, what does it mean?

The number inside of the triangle is a plastic identification number representing what chemical was used to make the plastic. For example if you see a 1 that represents PETE (Polyethylene Terephthalate) or a 7 represents Polycarbonate (which contains Bisphenol A), which are the two most commonly used chemicals in water bottles. This articles intent is to give a basic overview for #1 and #7 chemicals and is not inclusive by any means. I urge the reader to research each of these chemicals further.

Can I reuse my plastic water bottle?

Water bottles with the #1 (PETE) are for single use only! PETE leaches out into the solution within the second use. The more you reuse bottles made out of PETE the more of the chemical you are ingesting (Aquafina and Dasani are made out of PETE). Number 7 is rather stable in the beginning but with washing and continued use the pores of the plastic begin leaching polycarbonate and the more you wash and refill the more you are ingesting. I recommend not using bottles made with #7 (Nalgene is made with polycarbonate).

What is the health problem associated with chronic exposure to these chemicals?

PETE is thought to possibly be a carcinogen; there have been reported studies to support this claim. I am not yet sold on the exact condition it causes but drinking small amounts of chemicals cannot be good for anyone. Polycarbonate on the other hand is showing health concerns in a variety of ways. Bisphenol A (contained in Polycarbonate) was 1st introduced to the market in the 1930s as an estrogen for pharmacological use. It is now used in our plastics and has been shown to disrupt the endocrine system, fetus development, cause reproductive abnormalities and has been shown to enhance the growth of human breast cancer cells. These are dis-ease states that everyone should be trying to prevent from occurring.

Are there any bottles that are safe?

Bottles made by SIGG are coated on the inside with resin that have been proven to be resistant to breakdown and do not leach harmful chemicals. These bottles are looked upon as the gold standard when it comes to reusable containers.

Where can I purchase a bottle made by SIGG?

I purchase my bottles from either reusablebags.com or swissknifeshop.com. I have been told some Whole Foods stores are starting to carry these products, which is a good sign of things to come.

What is the Chiropractic connection?

Proper hydration is a part of the detoxifying, cooling and transportation process for every cell in the body. If the water you are consuming is contaminated with chemicals these process will be hindered and dysfunction will follow. Dysfunction in the body comes in the form of headaches, back pain, constipation or if in large enough amounts, even cancer.
