http://www.enn.com/sci-tech/article/38407Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate plastics have many applications including use in some food and drink packaging, e.g., water and infant bottles, compact discs, impact-resistant safety equipment, and medical devices. Epoxy resins are used as lacquers to coat metal products such as food cans, bottle tops, and water supply pipes. Some dental sealants and composites may also contribute to BPA exposure. Thus, human exposure to BPA majority through daily diet.
True to form, the U.S. FDA upheld their decision that BPA is safe and can remain in food packaging, including infant formula containers and baby bottles, despite the more than 100 independent studies linking the chemical to serious disorders in humans, including:
· Prostate cancer
· Breast cancer
· Diabetes
· Early puberty
· Obesity, and
· Learning and behavioral problems
A study published in the Environmental Health Perspectives in April 2008, discovered that BPA promotes the development of Th2 cells in adulthood, and both Th1 and Th2 cells in prenatal stages, by reducing the number of regulatory T cells.
This could have a profound effect on your health as Th1 and Th2 are the two “attack modes” of your immune system. Based on the type of invader, your immune system activates either Th1 or Th2 cells to get rid of the pathogen. Th1 (T Helper 1) attacks organisms that get inside your cells, whereas Th2 (T Helper 2) goes after extracellular pathogens; organisms that are found outside the cells in your blood and other body fluids.
When your Th2 are over-activated, your immune system will over-respond to toxins, allergens, normal bacteria and parasites, and under-respond to viruses, yeast, cancer, and intracellular bacteria, because as one system activates, the other is blocked.
After I have read through the article, I suggest that:
a) Don’t microwave polycarbonate plastic food containers. Polycarbonate is strong and durable, but over time it may break down from over use at high temperatures.
b) Reduce your use of canned foods.
c) When possible, opt for glass, porcelain or stainless steel containers, particularly for hot food or liquids.
d) Use baby bottles that are BPA free.

A study has once again reminded us that bisphenol A, a toxic chemical in plastics used in transparent baby bottles and food containers may cause damage to the brain and reproductive systems.Biphenol A is similar to the sex hormone estradiol. It has been proven in animal studies that biphenol A can cause brain damage, hyperactivity, abnormal sexual behavior, early puberty, and disrupted reproductive cycles, among other things.

BPA is nothing new to us actuallu. Only to know of its cientific name now but we know much of its consequenses such as cancer and many other disease relating from it.I too have received many awakening emails from well-wishers about this BPA. One of its clear effect is never drink water from a plastic bottle which has been left in the car under hot weather or for several days..I think ur articel is another alert for all of us.Thank you.
