Have you touched the ink from a cash register receipt lately? Were you aware that the ink contains BPA?
In a recent study done by the Journal of the Endocrine Society, BPA was linked to altering insulin release in healthy subjects at just one exposure of what was considered “safe” to the ink. The human study was conducted at the University of Missouri – Columbia where subjects were exposed to an amount of BPA comparable to handling cash receipts versus a control group. Insulin response was measured using an oral glucose tolerance test and hyperglycemic clamp. A strong correlation was found between hemoglobin A1C and the percent change in the insulinogenic index. Results showed an altered insulin release in exposed subjects versus the control group with the placebo exposure.
Take away: be conscious of not touching the ink from cash register receipts. Other areas where BPA may be hidden include canned goods (used in the internal lining and gets absorbed into the food), plastic containers (focus on plastic 3 or 7), and some baby formulas (make sure says BPA free). Alternatives include using glass containers as much as possible, buy frozen instead of canned goods, and purchase items that clearly state BPA free.
