According to a recent post on Grist, independent research has shown that high levels of Bisphenol A, commonly known as BPA, can be found in our canned food and drinks.
BPA is a main ingredient in most plastic, a material that currently dominates our lives. What’s unfortunate about the stuff is that it is a known endocrine disruptor. “Low-level exposure to BPA adversely affects male and female reproduction, thyroid function, metabolism, and could increase obesity,” according the a recent statement by the Endocrine Society. Prolonged exposure has been found to lead to increased likelihood of heart disease and diabetes.

However, what’s shocking is that manufacturers use the stuff to line our food and drink cans, and industry lobbyists are pulling the US Food and Drug Administration’s strings like puppeteers so that they can continue to expand this multi-billion dollar industry.
Besides canned goods, food substances that are actually packaged in plastic clearly contain more of the toxic substance.
In October 2008, the Canadian government issued a statement proclaiming it would draft regulations to prohibit the import, sale and advertising of baby bottles containing BPA (made of plastic). However, Health Canada still maintains that the amounts consumed by adults is within regulations. Nevertheless, retailers like Mountain Equipment Coop still pulled BPA-containing plastic water bottles off the shelves.

As a consumer, it’s hard to know what to avoid, considering all the different takes on the issue. Generally, the rule of thumb is if you must purchase products packaged in plastic, avoid ones with the recycling code 7 and containers that are unmarked, as they are more likely to contain BPA. Ones marked ’7 PC’ will always contain BPA.
Likewise, most plastic food containers are only meant for one-time use, as they are not strong enough to deal with cleaning, freezing and thawing. Eat Right Ontario states: “Do not use containers that are damaged, stained or have unpleasant smells and never use a container not meant for storing food.” While they tell you to recycle these containers rather than reuse them, I say avoid plastic products and packaging altogether.
I still find it hard to believe that any exposure is acceptable at all. Frankly, why would we take the risk when our health is concerned?
