Scientists have found a strong link between BPA and lower levels of thyroid hormone.
Commonly found in plastic materials, sales receipts on thermal paper, linings of canned food, and dental sealants, BPA is an estrogen-like compound that puts adverse affects on the brain and behavior of a person.
This chemical has also been found affecting prostrate gland in fetuses, infants as well as young children. Some studies have also discovered links between BPA and childhood obesity.
A new study by researchers at UC Berkeley's Center for Environmental Research & Children's Health revealed that BPA has been thyroid hormone levels toward the borderline.
According to the study, every doubling of BPA levels in pregnant mothers decreased total thyroxine (T4) by 0.13 micrograms per deciliter. It means their thyroids became less active. Doubling of BPA in mothers led to a 9.9 per cent decline in thyroid stimulating hormone in their male children.
Speaking about the findings, the study’s lead author Jonathan Chevrier,
"In addition, studies suggest that small changes in thyroid level, even if they're within normal limits, may still have a cognitive effect."
In July this year, the U. S. Food & Drug Administration (FDA) put a ban on use of BPA chemical in baby bottles and cups.
