There are disturbing findings from a new analysis of existing studies that reveal the pervasiveness of toxic ‘forever chemicals’: the data demonstrated that humans are now exposed to PFAS chemicals even before they are born. The analysis revealed that toxic PFAS chemicals were detected in every umbilical cord blood sample across 40 studies conducted over the last five years. The studies covered by the analysis collectively examined nearly 30,000 samples, and many linked fetal PFAS exposure to health complications in unborn babies, young children and later in life. The studies linked fetal exposure to higher total cholesterol and triglycerides in babies, and changes in their bodies’ bile acids, which can lead to a higher risk of cardiovascular problems later in life. Some studies also associated cord blood exposure with disruptions to thyroid glands and microbial cells in the colon.
What are PFAS chemicals?
PFAS (per- and polyfluoroalkyl substances), are a class of approximately 12,000 chemicals commonly used to make products resist water, stains and heat. They are called “forever chemicals” because they do not naturally break down, and instead, accumulate in human and animal bodies and the greater environment.
How are people exposed to toxic PFAS chemicals?
PFAS toxic chemicals are now ubiquitous in the U.S., present in our food, products, water and air. PFAS chemicals are contaminating drinking water for over 200 million people in the U.S. The toxic chemicals have also been found at alarming levels in meat, fish, dairy, crops and processed foods. They can also be found in numerous consumer products including nonstick cookware and cooking utensils, food packaging, waterproof clothing, stain-guards like Scotchgard found on upholstery, carpeting, clothing and other textiles, cosmetics, and even some dental floss.
Despite the overwhelming scientific evidence* that all PFAS chemicals that have been studied are persistent in the environment and toxic, the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) have resisted banning non-essential uses of the chemicals.
Why should we care?
PFAS chemicals (per- and polyfluoroalkyl substances) are toxic to humans, animals and the environment. They are comprised of approximately 12,000 compounds. PFAS chemicals present in products can be absorbed through the skin, swallowed or inhaled as they break off from products and move through the air. As a result, the U.S. federal government estimates from previous testing that PFAS chemicals are present in 98% of Americans’ blood.. They are ubiquitous in the U.S., appearing in thousands of consumer and industrial products and are typically used to make products resist water, stains and heat, including household products (like carpeting, curtains, furniture upholstery, waterproof and stain-resistant flooring, etc.), cooking supplies (including cooking utensils and bake ware), clothing, personal care products (like cosmetics, including waterproof mascara) and even food (PFAS appears in processed food packaging for humans and pets) and public drinking water (tap water) that affects an estimated 2 million Americans. PFAS chemicals are usually found in products labeled “stain-proof” and “waterproof”. PFAS chemicals also appear in fire-fighting foam and other industrial products used at airports and military bases across the country, where the chemicals have leached into the groundwater. PFAS chemicals are known as “forever chemicals” because they do not readily break down in the environment or human body. PFAS chemicals have been linked in scientific and medical studies to a variety of serious health conditions including cancer (including testicular cancers), kidney disease, heart disease, thyroid problems, reproductive problems, endocrine problems (PFAS has been found to disrupt hormonal functions with some research suggesting that the PFAS chemicals are linked to accelerated ovarian aging, period irregularities and ovarian disorders like polycystic ovarian syndrome) and liver problems. Some newer PFAS have been found to accumulate in organs, so in some cases, science simply cannot detect the toxic chemicals when testing for it in blood.
How can you avoid PFAS exposure?
PFAS chemicals are ubiquitous in our products, air, food and even water so it is impossible to completely avoid exposure. However, consumers–especially pregnant women–can minimize exposure to toxic PFAS chemicals by avoiding waterproof and stain proof household and personal care products (including cosmetics) and processed and pre-packaged foods and drinks, and using carbon filters in water purifiers if their public water system contains PFAS chemicals. And here are some PFAS-Free frying pans/skillets.
Additionally, we offer private consulting and coaching programs for learning how to detect chemicals of concern in food, products and environment and choosing cleaner alternatives for pregnant women and other consumers here. Or get our book here.
