Phthalates are plasticizer chemicals that gives plastic its physical properties.  Without them we would still be using glass, leather, natural fibers, metals, and rubber as we depended upon before the1960s when we were much healthier.

While phthalates are considered critical for construction, personal care products, food packaging, medical devices, vehicles, and appliances, their destructive effects on human health and reproduction should make us question their ultimate usefulness to the human race.

Globally, it is estimated that 200 times the toxic dose of phthalates for every man, woman, and child on the planet are produced every year for commercial uses. Current global production is estimated to be around 4-5 million metric tons annually (approximately 11 Billion pounds). 

Phthalates are absorbed across our skin, lungs and stomach/intestines and interfere with the production of testosterone and its useful metabolites. Worse yet, plastics degrade into microplastics which enter the air, water, and food chain, bringing their phthalates with them into your bloodstream. A recent study suggested that the human brain by old age contains a plastic spoon worth of plastic.

Even if we banned production of phthalates today, it would take many generations before the environmental levels are reduced to safe. If we as a species are to survive the duration of the suggested environmental clean-up, we require hormonal support and balancing, particularly testosterone.

Bisphenols’ common uses include: Polycarbonate plastics used in items like water bottles, eyewear lenses, and electronic components. They are used in epoxy coatings, adhesives, cosmetics, and in linings for food and beverage cans. They are in thermal paper used in receipts and labels.

While chemically different than phthalates, this notorious class of hormone disrupting chemicals has been shown to affect not only cardiovascular and endocrine systems leading to diabetes, heart attacks and strokes, but has also been shown to negatively change the brains of developing fetuses and infants (neuroendocrine disruptors).

This ever-present class of chemicals should be banned. 

While testosterone supplementation may well reduce bisphenols’ increased risk of cardiovascular complications and diabetes in adults; the developmental, reproductive, and neurological damage they do in young children and fetuses is not currently reversible.

PFAS has received much media focus recently. It is an unseen ingrediaent on food packaging, nonstick cookware, clothing, cosmetics, carpets, etc.

It is as destructive to human life as Phthlates and Bisphenols discussed above. While it has not been studied to the extent of the others, PFAS has been shown to decrease testosterone while increasing estrogen, a classic imbalance that creates chronic diseases.

PFAS has been associated with neurologic damage and diseases such as Parkinson’s and Alzheimer’s, diabetes, cardiovascular diseases, reproductive issues for both sexes, liver damage and more.
