Aluminum jar upsets the balance of hormonal messages in the body. Hundreds of scientific studies have shown that BPA is linked to developmental and reproductive abnormalities, cancer, and even neurological disorders in animal models.

In humans, the compound has been found to be linked to early onset of puberty, breast, uterine and prostate cancer, obesity and diabetes. By far the most common finding is that BPA in low doses is toxic during fetal and infant development. Pregnant women who were exposed to BPA had a higher than normal rate of birth defects and fetal and neonatal deaths.

Although BPA is only lethal at very high doses, increasing scientific evidence suggests that it can disrupt key body functions at very low doses, and builds up in our bodies over time with each exposure.

Despite the multiple Aluminum cap that clearly link BPA to developmental and other abnormalities in animals and humans, the US Food and Drug Administration (FDA) issued a statement on August 15, 2008 reaffirming the safety of products containing low levels of BPA. However, no mention is made of the effects of repeated exposure over many years, or of the effect of combinations of hormones and BPA.
