 What about food sources of BPA, a plastics chemical used for lining metal cans and in polycarbonate as opposed to PVC plastics? In humans, BPA is associated with cardiovascular disease, diabetes and male sexual dysfunction, exposed workers. Food is a major exposure source, but there weren't any studies reporting BPA in U.S. fresh can and packaged foods in the scientific literature until now. Before we get to what they found, what do they mean by male sexual dysfunction? The relationship between urine BPA level and declining male sexual function. Increasing urine BPA level was associated with decreased sexual desire, more difficulty having an erection, lower ejaculation strength, and lower level of overall satisfaction with sex life. This finding may have important public health implications given the widespread human exposure to BPA, but from where in our diet, in particular. They measured BPA levels in over 100 fresh and canned foods, foods sold in plastic packaging and in cat and dog foods in both cans in plastic packaging. Nearly all the canned foods were contaminated, from green beans to sardines, tuna and VA to Chef Boyardee. There was only one fresh, non-canned food that had detectable levels, so if you don't buy canned foods or stick to BPA free canned foods, the only food left to worry about appears to be sliced turkey.
