My article of August 11, 2011 discussed the connection between obesity and type-2 diabetes. Doctor Mark Hyman made the case that environmental toxins (chemicals) contribute to both conditions. This occurs because some of these chemicals interfere with glucose and cholesterol metabolism and induce insulin resistance.
In the meantime, the case for a causal linkage has gotten stronger. The organization Physicians for Social Responsibility (PSR) issued an alert on this issue. I quote from their article.
Certain chemicals are suspected of altering when, why and how much the body creates fat cells or stores fat in existing cells. Approximately 15 chemicals and classes of chemicals have been shown to cause weight gain in animal studies. They include: Bisphenol-A, Polybrominated Diphenylethers (flame retardants), some organochlorine pesticides, some phthalates, and perfluorinated organics. Although not a chemical, they include high fructose corn syrup. (See my blog of March 23, 2012.) They also point out that obesity results from dysfunction of endocrine systems, linked to hormone-disrupting chemicals. (See my blog of October 30, 2014, that summarizes finding of the World Health Organization.)
The PSR report ends with this sobering statement. It is now clear that susceptibility to obesity may start in utero or in childhood. Surely an alert for pregnant women and mothers of infants! Keep your body and your infant’s body free of the endocrine/hormone-disrupting chemicals.
