Numerous scientific studies and media stories report that we are exposed to chemicals in our daily lives. While these reports may be true, are they important for our health? And how do we know?
 
Many chemicals are naturally present in our diets and serve a beneficial purpose. For example, vitamins and essential elements are necessary for our health, and many chemicals account for the appealing tastes and aromas of everything we eat and drink. Other chemicals, for example trace levels of metals and synthetic chemicals, are contaminants that are not naturally present.

Listening to the Science Like FDA Does

As its name implies, one of the responsibilities of the U.S. Food and Drug Administration (FDA) is “ensuring the safety of our nation's food supply.”  Within FDA’s purview for this important responsibility are ingredients that are intentionally added to foods (e.g., the ingredients shown on packaged food labels) as well as materials such as packaging that contact food.

The Proof Is In the Pudding – BPA Is Safe!

It’s been a long time coming but the results are in and available for the world to see. The CLARITY Core study on BPA has now been published in peer reviewed scientific literature. This marks the completion of a multi-year study that was conducted by senior scientists with the U.S. Food and Drug Administration (FDA).
 
That may not sound like a big deal. After all, scientific studies are published every day with no fanfare received (or deserved). But this one is different and worth every bit of your attention.

The Media Fell For It Again

According to the headline on a recent press release, exposure to common chemicals in plastics is linked to childhood obesity. The headline further states that a new study “finds replacement chemicals for BPA aren’t safe for consumers.” Not surprisingly, journalists uncritically took the bait and reported the story just as written in the press release.

Che-mo-pho-bia: abnormal or excessive fear of chemicals (Merriam-Webster)
 
The term chemophobia has been defined by some as an irrational fear of chemicals. On the other hand, chemophobia might also be considered as a perfectly rational response to media stories related to chemicals. It’s easy to find scary stories about the hazards of chemicals, but it’s uncommon to find stories that inform the public about how chemicals help to make our lives better and safer.

Slovenia Joins 30+ Countries Listening to the Science on BPA

It’s generally accepted in the scientific community that the best way to measure human exposure to bisphenol A, otherwise known as BPA, is through an analytical method called biomonitoring. In particular, measuring the amount of BPA in urine is a widely accepted scientific practice for measuring exposure because BPA is rapidly and completely eliminated from the body in urine. What enters the body (i.e., intake) is readily measured by what comes out in urine.

Still Monotonic After All These Years

For just about everything we ingest in our daily lives, from aspirin to alcoholic beverages, small doses may be just fine for us. But too much of a good thing may be harmful. That common sense principle was first described by a Swiss physician named Paracelsus in the 16th century and is commonly stated today as “the dose makes the poison.”

Bisphenol F – From Mother Nature To You

Conventional wisdom tells us that substances naturally present in our diet must be safe, if not actually beneficial to our health. From vitamins to minerals, and protein to carbohydrates, a healthy diet includes a wide range of nutrients that we cannot live without.

The safety of any substance is dependent on the amount to which we are exposed.  Just about any substance could be harmful at high exposure levels, including things we commonly accept as safe.  For example, your doctor may tell you to “take two aspirin and call me in the morning” if you’re feeling under the weather, but a whole bottle of aspirin could act as a poison and kill you.
