Is BPA Really Risky? continued...
A panel of 38 BPA researchers recently issued a report saying they are
- Low doses of BPA have biological effects.
- BPA is everywhere -- in the water, in the air, and in the ground.
Estrogen-like effects now seen in wild animals are similar to those seen in lab
animals exposed to low doses of BPA.
- BPA levels commonly seen in humans are higher than those that cause adverse
effects in lab animals.
- BPA has different effects at different stages of life.
- BPA "reprograms" genes -- meaning that toxic effects may show up
long after exposure.
Toxicology Program's expert panel says there's "some concern" that
fetal exposure to BPA affects a baby's brain and causes later behavioral
However, the panel also found:
- "Minimal concern" that BPA affects the prostate
- "Minimal concern" that BPA accelerates puberty
- "Negligible concern" that BPA causes birth defects
- "Negligible concern" that BPA causes reproductive problems in
The American Chemistry Council supports the panel's findings. The
Environmental Working Group, a watchdog group that presses for BPA regulation,
blasts the report.
What Products Contain BPA?
Canned food appears to be the main source of BPA for most people.
Last March, the Environmental Working Group reported the results of a study
in which a national analytical laboratory tested 97 cans of food for BPA. The
cans were purchased at supermarkets in Atlanta; Oakland, Calif.; and
The study found that:
- Cans of chicken soup, infant formula, and ravioli had the highest BPA
- 1 in 3 cans of infant formula had BPA levels "200 times the
government's traditional safe level of exposure for industrial
- Overall, 1 in 10 cans tested had high levels of BPA.
- Beverage cans have fewer BPA residues; canned pasta and canned soups have
the highest levels.
BPA is an ingredient in many plastic products. A conservation group, the
Institute for Agriculture and Trade Policy, notes that plastic bottles with the
recycling number 7 (except new bio-labeled plastics) usually contain BPA.
Plastic baby bottles and "sippy" cups often contain BPA. Concerned
parents should avoid using these products if they are old, scratched, or have a
cloudy, cracked appearance.
To limit BPA exposure, the Environmental Working Group recommends:
- Consider using powdered formula, rather than canned formula, if your infant
- Avoid number 7 plastics, although not all contain BPA. Choose number 1,
number 2, and number 4 plastics.
- Use glass baby bottles, or those made with polypropylene and
- Pliable, milk-colored plastic does not contain BPA.
- Medela-brand bottles used to store breast milk are BPA-free.
- Metal water bottles may be lined with BPA-containing plastic.
- Avoid using plastic containers in the microwave.
- Avoid using old, scratched plastic bottles.
- Some plastic wraps contain BPA, although Saran and other brands
"promise to be BPA free."
