BPA is an agent added to plastics to make them flexible. It is found in plastic cups, water bottles, the plastic lining in canned goods, office water coolers, and plastic microwave trays. A recent study showed that consuming fresh foods reduced levels of BPA in the urine by 66% in just 3 days.
A study at the University of Kansas exposed rats to BPA in a manner designed to mimic human exposure. The animals were exposed to BPA every three days. Rats exposed to BPA became less active and avoided loud noise and strong light. They also showed signs of tenderness to the head. There were also signs of an influx of estrogen into the rats' brains. BPA has estrogenic properties and estrogenic fluctuations have been associated with migraine attacks.
