BPA in Food Packing Not a Great Cause Of Concern
BPA or Bisphenol A is a chemical that is commonly found in various consumer products. This chemical is used to make plastic food containers and also to seal various canned food items to prevent the chances of bacterial contamination of the food. Many manufacturers and dealers were giving importance to packing materials that are BPA free.
It was believed that the BPA absorbed by the body from the food stored in such containers causes much adverse effect on the human body. A latest study conducted by Justin Teeguarden of Pacific Northwest National Laboratory found that consuming food items which contain BPA do not cause the level of the BPA to increase to a higher level which causes health risks in humans.
No Risk from Oral Exposure
According to the study published by the toxicology and applied pharmacology department, the exposure to BPA from packaging is very low, and it does not cause higher than the level of BPA expected in blood.
The main concern about the use of BPA was its potential to act like certain hormones in the human body when exposed to high levels of BPA.The Authority of Food Safety in Europe and the Food and Drug Administration in United States confirmed their earlier assessment that BPA is safe when used in food packaging items recently.
In 2013, a study was conducted in dogs by placing concentrated solutions under the tongues of sleeping dogs. The publication of the results of this study caused many doubts about the conclusions made by the regulatory agency regarding the use of BPA containing packaging materials.
Teeguarden along with his colleagues, including from the FDA, were determined to find out if, absorption of BPA through the mouth tissues increased the BPA levels in human blood. The earlier studies looked at the results of digesting BPA containing food. They studied the result of people with normal eating behavior to assure the most accurate result. Ten volunteers were given warm tomato soup with a traceable form of BPA and multiple blood and urine samples were collected from the volunteers over a period of 24 hours.
- The research team found that consuming tomato soup containing traces of BPA as in the case of packaged foods did not cause any increase in the level of the active form of BPA in the volunteers.
- The studies till date have shown that the human body is capable of inactivating 998 molecules of BPA out of 1000 molecules by the time they enter the blood stream.
- The study also revealed that there are no chances of accumulation of BPA in humans as the entire dose gets eliminated through urine within 24 hours.
