Defend Your Health - Steer clear of Plastics

By Kim Jones


Plastics are not easy to stay away from during these times. Polycarbonate products are present nearly in every container we buy or use. Most of its use are in our day to day activities such as for meal preparations and food storage. Glass containers are very hard to find since almost everything is now in plastic. A lot of health problems have happened among the old and the young. It was unheard of when I was a teenager that a girl of eight would already have her menses. Today, that is not surprising considering BPA mimics the female hormone, estrogen. An astonishing 90% of the populace, as revealed in scientific investigations, have small traces of BPA in their bloodstream.

Even though the manufacture of Bisphenol begun in 1891, it was only in 1950 that its production were sold in the market. The problem is that the chemical Bisphenol or BPA, leaks from some containers. In science, BPA or Bisphenol A is described as the main ingredient in the production of polycarbonate material. Studies also noticed the adverse effect of bisphenol (even in little amounts), as it imitates the function of estrogen, the female sex hormone, on growing animals. Bisphenol A, branded as "environmental hormone", with traces of it in subjects involving animals and test tube experiments, it was found to be the cause of imbalances in their hormones. Breast cancer, prostate cancer, premature menses and structural changes in the brain are among its effects. Babies being fed on plastic bottles nowadays, that's really something to worry about! Bisphenol A or BPA is indeed a very harmful substance. Canada itself was the first country to implement safety measures to restrict BPA exposure. Folks, the knowledge of the dangers of this chemical has been around for a long time. The first evidence of its estrogenicity came from experiments in the 1930's feeding BPA to ovariectomized rats (Dodds and Lawson, 1936, 1938). The result of the research in relation to the consequences of BPA on humans were even underrated.

The principle of BPA is it hardens the plastic and giving it a lightweight feeling, creating a clear, heat resistant, electrical resistant, and shatter resistant material. Glass lenses, storage discs, computers, tools, headlights, equipments for safety in sports and medicine, incubators, reusable containers and can linings - these are but a few of the many products that is polycarbonate made.

Worldwide use of BPA has reached about three million in metric tons during 2003 as published in the Handbook of Chemical Economics by SRI Consulting in August of 2004.

To reduce your exposure to Bisphenol A, there are various ways to do that. If at all possible, buy your foods in glass jars such as tomato/spaghetti sauce, pickles, but especially tomato because the acid in the tomatoes causes more leakage of the BPA's. Garden fresh fruits and vegetables sold in the market is what you should pick because they do not contain any BPA. If you buy juices and sodas, choose the ones in the glass bottle. Also, for your baby's safety, use a glass bottle when feeding her/him.

I try to keep my utensils BPA free so I use glass or ceramic. Remember your pets need feeding too and they have a container of their own. Try to make sure that your using a glass container or ceramic or stainless steel and not plastic. There are birdbaths also that are created magnificently in colored glass or ceramic. It's an attraction in the yard for domestic and wildlife creatures to reduce its contact with BPA's and at same time, glass can be recycled. Whichever way you look at it, glass is still the best! Go glass, go green!
