Harvard Study: Canned foods spike BPA levels

According to the recent study conducted by Harvard University researchers, people who ate one serving of canned soup for 5 days in a row had a 1200% increase in their bisphenol A (BPA) levels, compared to those who ate the same amount of servings of fresh soup. And a significant increase in BPA levels could be measured after only one serving!

Why is this a big deal?

As the November 22, 2011 Harvard Press Release states: "Exposure to the endocrine-disrupting chemical BPA, used in the lining of metal food and beverage cans, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease, diabetes, and obesity in humans. In addition to the lining of food and beverage cans, BPA is also found in polycarbonate bottles (identified by the recycling number 7) and dentistry composites and sealants."

In another Press Release from October 24, 2011, a link has been made between BPA exposure in the womb and behavioral & emotional difficulties in young girls. It states: "...increasing gestational BPA concentrations were associated with more hyperactive, aggressive, anxious, and depressed behavior and poorer emotional control and inhibition in the girls. This relationship was not seen in the boys."

While some organizations don't agree (American Chemistry Council, bisphenol-a.org), new research seems to suggest that there is cause for concern. Reducing the amount of canned foods you eat is a good idea if you don't want to take the risk.
