Endocrine Disruptors in Depth

We've all probably heard the term endocrine or hormone disruptors multiple times and we are all probably aware that they are bad for us, but what are they exactly? How do they function?
According to the National Institute for Environmental Health Sciences:

"Endocrine disruptors are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife."

Endocrine disrupting chemicals (EDCs) can be natural or man-made. However, since WWII and our increasing dependence on synthetic chemistry, our concern has turned toward the over 80,000 new chemicals created. Many of these chemicals are EDCs.

Hormones in our body interact with specific target organs (made of cells). For example, estrogen targets the ovaries.  disrupt these pathways by interacting with the target organ, binding to hormone transport proteins, disrupting gene expression, inducing or inhibiting enzymes and interfering with cellular uptake and export.

EDCs can be found pretty much everywhere, from food to toys and pesticides. Unfortunately, we can't shop our way around this problem. We need strong legislation to rid ourselves of these chemicals once and for all. That is why I support Safer Chemicals for Healthy Families. Please Check out their website.

Are obesogens harming your weight loss plans?

Obesogens are endocrine disruptors; chemicals that disruptor our body's hormone systems. Obesogens disrupt the way our body regulates our weight. Resulting in decreased calories burned, increased fat cells and even changes in the way your body manages hunger. 

According to Dr. Oz, obesogens work by the following methods:

• "Encourage the body to store fat and re-program cells to become fat cells.
• Prompt the liver to become insulin resistant, which makes the pancreas pump out more insulin that turns energy into fat all over the body.
• Prevent leptin (a hormone that reduces appetite) from being released from your fat cells to tell your body you are full."

You'll find obesogens in the following places:

• flame retardants = found in furniture and electronics
• Bisphenol A(BPA) = plastics with recycling number 7 on the bottom, receipts, lining of cans
• phthalates= new car smell, fragrance in personal care products
• triclosan = antibacterial soaps and hand sanitizers
• polyvinylchloride (pvc) = shower curtains. Look for non pvc curtains.
• Perfluorooctanoic Acid (PFOA) = teflon cookware. Try cast iron pans.
• high fructose corn syrup
• atrazine  = pesticide (atrazinelovers.com). Get a water filter to avoid this.
• microwave popcorn
• vinyl flooring, industrial strength plastic wrap, grocery store plastic wrap over meat. Ask for meet wrapped in brown paper.
• air fresheners. Try dried herbs and flowers.
• Polybrominated biphenyls (PCBs) = industrial chemicals that enter the food chain and enter our diet through fish and meat. Try Meatless Mondays.

Toxic Chemicals to Avoid

I thought I would devote a post to listing some chemicals that we need avoid that are in the products we happen to use everyday. I should add the disclaimer that as a consultant for Ava Anderson Non Toxic, I go over some of this list at parties and I do offer products that do not contain these chemicals as  they pertain to personal care products. That said, this list is still valuable information for all consumers. The truth is, these chemicals shouldn't be in any products and consumers shouldn't need a degree in order to understand the information on the back on the products they purchase. There are over 80,000 chemicals on the market, the vast majority having never been tested for safety.  For more information on this issue, please see sources below.

Many of the chemicals on the list are endocrine disruptors, meaning they disrupt the body's endocrine (hormone) system by mimicking or blocking our normal hormonal signalling pathways. Our endocrine system regulates ALL of the body's biological processes, including brain and nervous system development, blood sugar levels, metabolism, growth and function of the reproductive system, the pituitary, adrenal, and thyroid glands. According to the UN and World Health Organization, endocrine disrupting chemicals (EDCs) and are a global threat and can be a threat to the developing fetus.

Chemicals to Avoid

• Fragrance/Parfum/Perfume: This is a term used by industry to hide thousands of other toxic  chemicals. More than 3/4 of the time, this term is used to hide the presence of phthalates (THAL ates), which are known endocrine disruptors.  Phthalates are linked to birth defects, infertility, breast cancer, liver cancer, obesity, and diabetes.

• Triclosan: This is the active ingredient in "anti-bacterial" products. It's registered with the EPA as a pesticide and is also a known endocrine disruptor, disrupting thyroid function.

• Parabens: Parabens are preservatives linked to breast cancer, endocrine disruption, developmental defects, and reproductive toxicity.

• Oxybenzone and Octinoxate: These are chemical UV filters found in many spf products and suncreens. They are also known endocrine disruptors. 

•  DEA (Diethanolamine), MEA (Monoethanolamine), TEA (Triethanolamine): These are endocrine disrupting chemicals that have strong links to liver and kidney cancer.

• Petrolatum: This is a derivative of petroleum. It is a carcinogen and an endocrine disruptor.

•  PEGs (polyethylene glycol): These are byproducts of petrolatum. During the manufacturing process, the carcinogenic contaminant 1-4 dioxane is created.

•  Sodium Lauryl Sulfate (SLS) & Sodium Lauryth Sulfate (SLES): These chemicals are considered carcinogens. SLES can be contaminated with 1-4 dioxane, although you will never see 1-4 dioxane on the label. Manufacturers aren't required to list carcinogenic contaminants. 

• Ingredients that end in -eth:  Examples are triceteareth and ceteareth. These can also be contaminated with 1-4 dioxane. 

• Retinyl Palmitate:  This can be found in many sunscreens and moisturizers, however in the presence of sunight, it enhances skin cancer lesions by 21% (FDA, 2011).

•  Synthetic Colors: These are made from coal tar and are labeled as FD&C or D&C followed by a color and a number, for example, FD&C Red No. 6. These are carcinogenic and have been linked to behavioral problems in children.
