Recent tests by Consumer Reports’ in canned foods, including soups, juice, tuna and green beans, found that almost all of the 19 foods tested contained trademarks measurable levels of BPA (bisphenol A).
What is BPA?
The BPA, which has been used for years in transparent plastic bottles and coatings of food cans has been restricted in Canada and some states and municipalities throughout the United States due to potential health effects. But there are no federal restrictions on the use BPA in food packaging.
At present, federal guidelines place the upper limit of safe exposure to 50 micrograms of BPA per kilogram of body weight. But that level is based on experiments in the eighties, instead of the hundreds of studies in laboratory and animal studies conducted more recently, indicating that much lower doses of BPA could lead to serious health risks.
According to studies done in laboratory, abnormal reproductive development, increased risk of breast and prostate cancer, diabetes and heart disease, all with a dose that a person could reach or eating a few servings a day.
How to avoid BPA?
Can be found in some canned foods, even in “organic” in cans and BPA-free (BPA free). The highest levels of BPA were found in some samples of canned green beans and canned soups as:
Blue Lake Green Beans Fresh Del Monte had the largest amount of BPA detected and followed the Progresso vegetable soup, Campbell’s condensed soup, chicken and pasta, Chef Boyardee Beef Ravioli in tomato sauce and meat. And he found BPA in some products packaged in cans that do not contain BPA declared (BPA-free) as Vital Choice tuna and canned baked beans Eden.
Conscious consumers can reduce, but not necessarily eliminate, exposure to BPA in their diets, taking the following precautions:
– Whenever possible, choose fresh foods.
– Consider alternatives to foods, beverages, juices and infant formula, canned.
– When heating food in microwave, use glass containers.
