Bisphenol A, often known as BPA is a chemical commonly found in hard plastics and the coatings of food and drinks cans. BPA is used to make many products, including water bottles, baby bottles, dental fillings and sealants, dental devices, medical devices, eyeglass lenses, DVDs and CDs, household electronic and sports equipment. BPA can also be found in epoxy resins which are used as coatings inside food and drinks cans. This chemical can also behave in a similar way to estrogen and other hormones in the human body.
BPA is an endocrine disruptor, which means it mimics or interferes with your body's hormones and "disrupts" your endocrine system. The glands of your endocrine system and the hormones they release influence almost every cell, organ, and function of your body. It is instrumental in regulating mood, growth, and development, tissue function, metabolism, as well as sexual function and reproductive processes. BPA has been linked to a number of health concerns, particularly in pregnant women, fetuses, and young children, but also in adults. Some of the more adverse effects include:
- Structural damage to the brain
- Hyperactivity increased aggressiveness and impaired learning
- Increased fat formation and risk of obesity
- Altered immune function
- Changes in gender-specific behavior, and abnormal sexual behavior
- Early puberty, stimulation of mammary gland development, disrupted reproductive cycles, ovarian dysfunction, and infertility
- Stimulation of prostate cancer cells
- Increased prostate size and decreased sperm production
Much of the research on BPA has involved animals, leading skeptics (usually those in the chemical industry) to say the effects may not necessarily be the same in humans; but research involving humans has shown similar risks. For instance, BPA from cans or plastic bottles can raise your blood pressure within just a few hours of ingestion. In the NHANES study, published in 2010, adults with the highest levels of BPA in their urine were more than twice as likely to develop coronary heart disease as those with the lowest levels. The problem is, BPA is also a synthetic estrogen, and plastics with BPA can break down, especially when they're washed, heated or stressed, allowing the chemical to leach into food and water and then enter the human body. That happens to nearly all of us; the CDC has found BPA in the urine of 93% of surveyed Americans over the age of 6. If you don't have BPA in your body, you're not living in the modern world.
Studies have shown that most Americans have BPA in their blood, usually in the range of 1 part per billion (ppb). This might seem like too minuscule an amount to cause problems, and that’s just what regulators and chemical companies have long stated, but “endocrine disruptors like BPA, which act like hormones, don’t “play by the rules,” says Patricia Hunt, a geneticist at Washington State University.” According to Hunt, “exposure to low levels of BPA levels that we think are in the realm of current human exposure, can profoundly affect both developing eggs and sperm.” For instance, in one of Hunt’s studies, researchers found disruptions to egg development after rhesus monkeys, which have human-like reproductive systems, were exposed to either single, daily doses of BPA or low-level continuous doses. The BPA appeared to damage chromosomes, which could lead to spontaneous miscarriage or birth defects. In the group exposed continuously to BPA, there were not only problems with initial egg development, but also in the fetal eggs that were developing. The fetal eggs were not "packaged" properly in the follicles, which mean they would have difficulty developing and maturing normally.
In 2008, more than 22 billion cans of food and more than 100 billion cans of beer and soft drinks were produced with BPA. In 2011, an estimated 10 billion pounds of BPA chemical were produced for manufacturing polycarbonate plastic, making it one of the highest volume of chemicals produced worldwide. The Environmental Protection Agency (EPA) calculated that people consume 50 micrograms of BPA per kilogram of body weight every day over the course of a lifetime. Over 40 studies have found adverse health effects in rats given less than one-hundredth of that amount.
FDA has already amended its regulation to no longer provide for the use of BPA-based polycarbonate resins in baby bottles and sippy cups and in packaging for infant formula.
