Who Is Protecting Us From The Safe Products?
“Until recently, many reusable, hard and clear, plastic products were commonly synthesized using BPA, a chemical known to have estrogenic activity (EA) that leaches from polycarbonate (PC) plastic products.”
“BPA is by far the best studied as an estrogenic chemical released from reusable hard and clear PC-type products…”
“Chemicals are said to have EA…the most common form of endocrine disruptor activity…if they mimic or antagonize…actions of naturally occurring estrogens…”
“Chemicals with EA…can produce various adverse health effects…such as early puberty in females, reduced sperm counts, altered functions of reproductive organs, obesity, altered sex-
specific behaviors, and increased rates of some breast, ovarian, testicular, and prostate cancer.”
“…in vitro data overwhelmingly show that exposures to chemicals having EA (often in very low doses) change the structure and function of many human cell types…”
“many…studies document in detail cellular/molecular/systemic mechanisms by which chemicals having EA produce changes in various cells, organs, and behaviors….(And) recent epidemiological studies…strongly suggest that chemicals having EA produce measurable changes in the health of various human populations…”
“In response to market and regulatory pressures, BPA-FREE…resins and products have recently been introduced as replacements for PC resins.”
“However, all such replacement resins and products tested to date
(> 500 commercially available plastic products that we sampled—even those that are presumably BPA free)
release chemicals having EA, sometimes having more EA than BPA-containing PC resins or products, especially when stressed by UV light..”
“However, most importantly, some reusable, BPA-free, hard and clear PC-replacement products could be found that did not release chemicals with EA…”
“All of our data suggest that, when both are manufactured in comparable quantities, carefully formulated EA-free plastic products could have all the fit-for-use properties of current EA-releasing products at minimal additional cost.”
“Consequently, it is possible to manufacture EA-free PC-replacement products in commercial quantities and thereby avoid potential adverse consequences to the environment or human health…”
It seems likely that at some point in the future, plastic products will be required to be produced in such a way that significantly reduces or eradicates their potential estrogenic effects. As these and other studies have shown, it is possible for this transition to take place using existing manufacturing equipment, with very little in the way of added financial burden for industry.
Estrogen as well as estrogen mimicking or promoting substances interact powerfully with many other inflammatory stress related substances, including bacterial endotoxin, serotonin, as well as the thyroid suppressing, inflammation producing, polyunsaturated fats and their breakdown products, potentially leading to a vicious cycle of excessive production of estrogen relative to progesterone levels, and the development and promotion of many degenerative diseases.
Although it may not be practical or even possible to completely avoid exposure to harmful plastics which have become ubiquitous in the current environment, maintaining a healthy thyroid metabolism is protective against estrogen and estrogenic substances.
A diet restricting fats, with sufficient intake of sugars in the form of milk and sweet ripe fruits, fruit juice, honey and sugar, helps to promote metabolism, minimise the release of polyunsaturated fats from storage and protect from some of the damaging effects of estrogen and environmental estrogenic substances.
Where possible, avoiding lengthy exposure of plastic products to UV radiation, or microwave ovens is likely to be beneficial.
