Bisphenol A (BPA), the chemical that is present in many types of plastic bottles also appears to be in canned drinks as well. A recent joint study by Health Canada and Environment Canada, using a sampling of 72 canned drink products (carbonated, non-carbonated, tea drinks, diet, fruit-flavoured, energy drinks, etc.) covering an estimated 82% of the market, found that BPA was present, in varying levels, in almost all the canned drinks sampled.
BPA concentrations varied from 0.045 µg/L to 0.57 µg/L. The studied concluded that the variation of BPA levels in canned drink products could be a result of, “…differences in can coatings (type, amount etc.), can sterilization conditions, and accidental exposure of the canned drink products to heat during storage and transportation”.
The study also concluded that based on the tolerable daily intake of BPA of 25 µg/kg body weight/day as established by Health Canada, means that a person would need to consume an estimated 940 canned drinks in one day to approach the provisional tolerable daily intake.
However, if you want to avoid ingesting BPA in any quantity, canned drinks may also need to be eliminated from a healthy diet.
