Article 4: Are We Threaten By Biphenol A???

http://www.enn.com/sci-tech/article/38407

Bisphenol 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.
