Tests Find Bisphenol A in Majority of Soft Drinks
A new study conducted by Health Canada has linked the highly controversial estrogen-mimicking chemical BPA to 96% of soft drinks, showing up in quantities below regulatory limits, but worrisome to some. A growing body of science suggests the chemical may have harmful effects at levels far below Health Canada's limit.
Soft drink cans are treated with BPA, a chemical used in the hardening of plastics to prevent drinks from coming into contact with metal. Last year, Health Canada banned plastic baby bottles that contain BPA, and are now frowning upon water bottles that contain it.
The study was released quietly in the Journal of Agricultural and Food Chemistry in January and the Health Canada authors downplayed the findings, saying the levels detected are well below current recommendations.
Tests by Health Canada scientists revealed the highest levels were in energy drinks, the often caffeine-loaded beverages that have become popular with teenagers seeking a buzz and athletes chasing a quick pick-me-up. But the study also found the controversial compound in a wide variety of ginger ales, diet colas, root beers and citrus-flavoured sodas.
While the levels are low, some environmentalists say the levels may very well be enough to cause harm to children, especially those who drink a lot of pop or energy drinks.
