Moms everywhere are ditching their baby bottles, binkies and sippy cups for newly marketed BPA-free ones. However, BPA and phthalates are just two of several hundred chemicals that exhibit estrogenic activity (EA) in plastics. Estrogenic activity occurs when chemicals are ingested that mimic or block the actions of naturally occurring estrogens, the female sex hormone. Studies have proven the fetus, newborn and young child is particularly vulnerable. Health-related problems as a result of estrogenic activity include: early puberty in females, reduced sperm counts in males, altered functions of reproductive organs, obesity, altered behaviors and increased rates of some breast, ovarian, testicular and prostate cancers. Chemicals having EA leach from almost all plastics sold today. That is, plastics advertised as BPA-free or phthalate-free are not EA-free. Almost all these plastics still leach chemicals that contain EA. In fact, our data at PlastiPure show that all the plastics commercially available today do release chemicals with easily detectable EA. The FDA has yet to examine this broader problem. The amount that leaches from any one item may be small, but the cumulative effect of leaching from many items is significant and can be detected in the blood and tissues of almost all of us. And our children are the most susceptible. Unfortunately, current legislation is attempting to solve this problem by removing chemicals having EA like BPA and phthalates just one at a time. This approach is ineffective since thousands of chemicals still used in plastics exhibit EA, not just BPA and phthalates. The appropriate health-driven solution is to manufacture safer plastics that are completely EA-free. This is not a pie-in-the-sky solution, as the technology already exists to produce EA-free plastics that also have the same advantageous physical properties, as do almost all existing plastics on the market today. In fact, some of these advanced-technology EA-free plastics are already in the marketplace. The cost of safer, EA-free plastics is just pennies more than EA-releasing plastics when both are used to manufacture the same product in similar quantities Recently, numerous publications have been writing about the dangers of BPA and phthalates and many companies are jumping on board promoting baby bottles and other plastics as BPA free.
