At a recent meeting of the International Society of Endocrinology and the Endocrine Society (ICE/ENDO) it was revealed that bisphenol 5 (BPS), a chemical found in “BPA free” products can alter brain development and cause what is classified as hyperactivity behaviors.
Deborah Kurrasch, professor at the University of Calgary in Canada and lead author of the study said in a press statement: “BPS, termed the safe alternative to BPA, may be equally as harmful to developing brains. Society must place increased pressure on decision makers to remove all bisphenol compounds from manufacturing processes.”
Kurrasch pointed out that “BPA-free does not mean bisphenol-free. I’m not sure that’s recognized in society.”
This study looked at the effects of BPS on zebrafish because they are “developmentally similar to humans”.
Corporations who removed bisphenol A (BPA) from their products have replaced it with BPS because it is assumed by industry standards and the public that BPS is safer.
The label “BPA free” may indicate the use of BPS, and its established safety for consumption by humans “has yet to be examined and established.”
The study monitored “zebrafish embryos during the second trimester, a crucial time for brain development, specifically, neuronal generation in the hypothalamus. Developing embryos were exposed to a low dose of either BPA or BPS, and the researchers saw that neuronal birth increased during that time period for both bisphenol groups compared with typical zebrafish development.”
Because of the assumption that BPS is a “safe alternative” to BPA, researchers of this study warn that “BPA-free products [are] equally [as] harmful to developing brains” as BPA laced products.
Kurrasch’s team is calling for a “continued societal push to eliminate all bisphenol analogs from consumer goods production.”
In 2013, a study headed by Di-Kun Le, reproductive and perinatal epidemiologist at the Kaiser Permanente Division of Research, showed that BPA can be linked to causing obesity in pubescent girls.
Le concluded that because BPA affects the endocrine system, exposure to this chemical is directly contributing to the global obesity issue because BPA “is an endocrine disrupter and acts similarly to the hormone estrogen, which impacts metabolic function.”
Le explained: “Overeating a little won’t cause obesity, but (by) having this kind of endocrine damage without knowing it, and adding more food, the consequences are magnified.”
Another study published that same year show the link between BPA and migraines.
Researchers at the University of Kansas tested laboratory rats. Half were given BPA laced products and the control group has not given BPA.
Just being exposed to the chemical for 3 consecutive days, the rat became lethargic, sensitive to loud noises and light, was easily startled and showed signs of suffering from headaches.
The study states: “A previously performed study using a ‘fresh foods’ dietary intervention demonstrated a significant decrease in urinary BPA (66 per cent reduction) in patients after just three days. These findings combined with our results suggest that a clinical trial to decrease BPA exposure and levels in migraine sufferers…may reduce headache frequency and/or severity, revealing strategies that may increase the quality of life of migraines.”
Testing showed the rat’s brains were flooded with oestrogen, a synthetic mimic of the female hormone estrogen.
Oestrogen “is a female hormone that is used to treat women’s health problems including menopausal symptoms.”
This patented chemical “is a combination of two female hormones, an oestrogen and a progestogen.”
Oestrogen must not be consumed by the general public because adverse effects include:
• Vaginal bleeding
• Development of breast-tissue tumors
• Blood clots in legs and lungs
• Aggravate diabetic conditions
• Cause kidney or liver problems
• Chest pain simulating a heart attack
• Exacerbate allergic reactions
According to the study: “These results imply that BPA has the ability to amplify symptoms that are used to diagnose the disorder in human patients, suggesting that exposure to BPA would increase both the incidence and prevalence of this disorder.”
A report entitled, “Disrupted Development: the Dangers of Prenatal BPA Exposure”, released by the Breast Cancer Fund (BCF) confirmed that BPA must be removed from all bottles and packaging because of the evidenced risk to children and babies in utero.
According to the paper, babies are exposed in the womb by mothers who consume BPA. This is quite dangerous to the development of the unborn baby within the first 11 weeks of life because “everything is being developed”.
The study cites more than 60 animal and human studies wherein BPA is shown to cause:
• Breast cancer
• Prostate cancer
• Early puberty
• Neurological disorders
• Immune system compromises
The Food and Drug Administration (FDA) asserted in 2012 that there is not enough convincing evidence to support the banning of BPA from use in food products, plastic packaging and personal care products.
According to the FDA: “While evidence from some studies have raised questions as to whether BPA may be associated with a variety of health effects, there remain serious questions about these studies, particularly as they relate to humans.”
