When I was in junior high school, I distinctly and embarrassingly recall being a little obsessed with a certain cheesy teen novella called “8 Days to a Brand-New You” — a romantic and moving make-over tale in which our geeky, bespectacled heroine becomes a total babe in eight short days (or something like that). You can see the appeal.
My friends are accusing me of always being the bearer of bad news, and it’s certainly a fair charge. But I also still cling firmly to the belief that it’s possible to make small and easy changes that will transform your life. Or at least improve things a little bit.
In the bad hair-day backstage video I did for the ANDERSON show, I mention that you can quickly and immediately see results in efforts to decrease levels of Bisphenol-A (BPA), a potent endocrine disrupting chemical that behaves like a hormone in the body and has been linked to reproductive health damage and other serious concerns.
How do I know this? Last year, researchers set out to pilot new research methods by doing a small, short study of 20 people in five families in the Bay Area, co-sponsored by the Breast Cancer Fund, an organization focused on prevention of breast cancer by identifying and eliminating links to toxins. The results were astonishing, as summarized here and below:
Participants ate their usual diet, followed by three days of fresh foods that were not canned or packaged in plastic, and then returned to their usual diet.
The researchers collected evening urine samples over eight days in January 2010 and categorized them as pre-intervention, intervention, or post-intervention samples.
Test results showed an average drop of 60 percent in BPA levels when study participants ate a diet that avoided contact with food packaging containing BPA, which is used to make polycarbonate plastics and in the lining of food cans.
Tests showed a 50 percent average drop in DEHP, a phthalate commonly added to some food containers and plastic wraps to increase flexibility.
People with the highest levels of BPA prior to the intervention dropped their levels of BPA by 76 percent, and for DEHP that gap dropped by a stunning 93 to 96 percent. Study participants were shocked by the dramatic results.
The key was to prepare fresh foods, and to reduce incidental use of plastic. Three days was all it took, because the body flushes BPA and DEHP quickly, and it stays out so long as we don’t reintroduce it.
Here are some simple tips to reduce these types of exposures:
1) Don’t eat from plastic where it can be avoided. For example, avoid plastic water bottles of all kinds, including baby bottles and sippy cups, plastic drip coffee makers (we use a stainless steel electric kettle and glass french press), and most canned foods, particularly for sweet, acidic, or fatty items (which, let’s face it, is basically everything).
2) Try to frequent restaurants where the food is fresh and to order items that are unlikely to have been frozen (because they’re often stored in plastic) or canned. Just ask what’s fresh — a decent waiter at a good restaurant will tell you, and it’s a good guide to what the chef is excited about anyway.
3) Don’t heat plastic in the microwave or dishwasher or use plastic utensils for cooking or eating.
4) Store food in glass and food-grade stainless steel (some options are identified here in the Kitchen Gear section, and in the comments here), and keep food well below the level of the lid to minimize contact, as they did in the study. Avoid plastic wrap, especially the cheap kind like they use at the deli counter, which is usually PVC, or, at home, use a bowl to keep it away from the food and check to make sure what you’re using is labeled “PVC-free.”
5) Avoid jarred baby food and ready-to-use formula for infants, as they likely have BPA or a potentially suspect BPA-substitute in the lid. Preparing fresh baby food and using dried formula powder from cans are safer choices whenever possible.
6) As this article from the Natural Resources Defense Council says “[d]on’t allow your children to have dental sealants made from BPA (or BADGE) applied to their teeth, and don’t have these sealants applied to your teeth while you are pregnant. Ask your dentist to provide BPA-free treatments.”
8) Sadly, recycled paper products, like toilet paper and napkins, are also high in BPA, likely due to receipts in the recycling chain. I’m still wrestling with my conscience over this one, but for pregnant women in particular, avoiding all kinds of recycled paper is likely a good idea.
A few other thoughts:
1) While many sites recommend Tetra-paks, for the reasons I explain here, these just store food in a polyethylene layer of plastic, which poses basically the same level of risk as a water bottle (or even more risk for acidic foods given their tendency to leach chemicals from plastic). Confirming my hunch, some links to German studies demonstrating that Tetra-paks leach more estrogens than water bottles, as well as some additional facts about how they make these types of packages sterile that may contribute to this leaching process, are here.
2) There are some BPA-free canned foods on the market, including Eden brand beans (not tomatoes), Muir Glen canned tomatoes (not glass jars; the lids have BPA), and Native Forest coconut milk (this was on several Websites; for example, here, but is not on their site and is not labeled on the can, so I will confirm with the company and update this post; as a side issue, I just noticed that they do use fillers like guar gum, which may be hard to digest for some; you can also evidently make your own coconut milk from dried coconut).
4) A depressingly large number of brands still use BPA, as this helpful local co-op page demonstrates. Another list is here, as well as comments pointing out that toothpaste tubes also have BPA! (I’ll look into this a bit and report what I find.)
5) Stonyfield Farm yogurts are probably in better packaging, as the company really put its plastic supplier through some paces. It’s just too bad that the sugar levels in their yogurt for babies, toddlers and kids are so darn high.
5) When you can’t use fresh, frozen organic foods are likely safer on this front, but do check the small print on the packaging, as many frozen brands are organic “made in China” or in other places in which organic certification is, IMHO, at least suspect (more on this in a future post). Also, salt is often added to frozen veggies, which may be undesirable if you’re cooking for a child.
6) The issue with all BPA-free canned foods is, of course, the question of what they are using instead. About this, companies are remarkably tight-lipped, as I explore here. One exception to this rule is Eden foods, which comes right out and says their substitute is oleoresin, a mixture of pine sap from trees.
For this reason, I’ll use the Eden canned beans in a pinch, though I still prefer the far more toothsome texture of soaked dried beans. (A tip: getting a decent pressure-cooker really helps to make cooking beans a bearable use of time. It’s a staple item in an Indian kitchen for dal and the like, so we have one and use it almost daily.)
