The BPA Issue Is Worse Than We Thought
A research team connected with UCLA in the US has discovered a correlation between BPA exposure and reproductive dysfunction, which does not bode well for future generations. A mutating effect has been found.
According to David Baggs, Ecospecifier Global's Technical Director and Global GreenTag’s CEO and Program Director:
“BPA is a chemical found in plastics, such as some epoxy coatings and polycarbonate plastics and in unregulated food related items such as water bottles and epoxy linings to steel cans, and as a result can leak into the users’ diets.”
In a study published in May, researchers in the laboratory of Patrick Allard, an assistant professor in the UCLA Institute for Society and Genetics, demonstrated that BPA (Bisphenol A) a chemical used to strengthen many plastics, caused fertility defects in worms that could still be observed five generations after the parent worms were exposed to BPA.
The research suggests environmental chemicals may have similar effects on human health for many generations. Lisa Truong, a graduate student working in the Allard Laboratory and an author of the study said:
“(Seeing the effects of BPA over many generations) was surprising and very concerning,”
Patrick Allard said his lab studies show how germ cells, the cells that make sperm and eggs, pass on their memory of environmental conditions, such as diet and chemical exposure. Cells keep track of their memory across generations by tagging their DNA with molecular markers and passing on those DNA marks to the embryo at fertilization.
“We found that (the cellular process of marking DNA) is highly influenced by the environment.”
Truong added that throughout development, cells mark their DNA to activate or silence particular genes, allowing the cell to choose carefully which proteins are necessary for that specific stage in development.
This latest research found reproductive cells from worms that had parents exposed to BPA had fewer silencing marks. This misregulation of DNA marks led to the inappropriate activation of genes in the reproductive cells and caused fertility defects.
Health issues linked to product choices is a serious topic.
It is strongly advised to find trusted information about a product and what it contains and not just rely on claims made by manufacturers. To be sure that a product is safe for human health and the environment, look for product information only that has been assessed by third party verifiers like Ecospecifer Global or more deeply assessed by certification bodies like Global GreenTag International, which now also offers manufacturers the opportunity to make full Product Health Declarations with their GreenTag PhD assessments and HealthRATE™ product health ratings.
