Fibromyalgia, characterized by chronic, widespread pain is an often-debilitating condition that primarily affects women. While as many as 10 million Americans have fibromyalgia, its cause remains a mystery.
Brain scans of fibromyalgia patients have offered hard evidence that the pain they experience is indeed real — mainly because their threshold for tolerating pain impulses is substantially lower than that of most individuals. But the mechanism causing this lowered pain threshold is still unknown.
Some experts, such as Dr. Frederick Wolfe, the director of the National Databank for Rheumatic Diseases and the lead author of the 1990 paper that first defined fibromyalgia's diagnostic guidelines, believe fibromyalgia is mainly a physical response to mental and emotional stress.
But while stress and emotions may indeed play an important role, more recent research shows fibromyalgia patients tend to have severe inflammation in their body, including their nervous system and brain.
Diagnosis can be a challenge, but the updated case definitions of fibromyalgia, issued in 2010 and later simplified in 2012, claim to correctly diagnose about 83 percent of cases.1 Originally, the condition was thought to be a peripheral musculoskeletal disease. Today, fibromyalgia has become increasingly recognized as a neurobiological problem causing central pain sensitization.
Unfortunately, there are currently no laboratory tests available for diagnosing fibromyalgia, so physicians primarily depend on patient histories, reported symptoms and physical exam findings. Classic symptoms of this condition include:
• Pain — The key marker of fibromyalgia is pain, which is profound, widespread and chronic. Pain inside of your elbows and knees, collarbones and hips is indicative of fibromyalgia when it's present on both sides.
People also frequently report pain all over their bodies — including in their muscles, ligaments and tendons — and the pain tends to vary in intensity. It has been described as deep muscular aching, stabbing, shooting, throbbing and twitching.
Neurological complaints add to the discomfort, such as numbness, tingling and burning. The severity of the pain and stiffness is often worse in the morning. Aggravating factors include cold/humid weather, nonrestorative sleep, fatigue, excessive physical activity, physical inactivity, anxiety and stress.
• Cognitive impairment — So-called "fibro-fog" or foggy-headedness is a common complaint.
• Fatigue — The fatigue of fibromyalgia is different from the fatigue that many people complain of in today's busy world. It is more than being tired; it's an all-encompassing exhaustion that interferes with even the simplest daily activities, often leaving the patient with a limited ability to function both mentally and physically for an extended period of time.
• Sleep disruption — Another major part of the diagnostic criteria for this condition is some type of significant sleep disturbance. In fact, part of an effective treatment program is to make sure you're sleeping better.
Medical researchers have documented specific and distinctive abnormalities in the Stage 4 deep sleep of fibromyalgia patients. During sleep, they are constantly interrupted by bursts of awake-like brain activity, limiting the amount of time they spend in deep sleep.
• Other symptoms — Other common symptoms include irritable bowel and bladder, headaches and migraines, restless leg syndrome and periodic limb movements, impaired memory and concentration, skin sensitivities and rashes, dry eyes and mouth, anxiety, depression, ringing in the ears, dizziness, Raynaud's Syndrome and impaired coordination.
Conventional treatment typically involves some form of pain medication, and perhaps psychotropic drugs like antidepressants. I don't recommend either as they fail to address the cause of your problem. Many fibromyalgia sufferers also do not respond to conventional painkillers, which can set in motion a vicious circle of overmedicating on these dangerous drugs.
Using PET imaging, a recent investigation2 by researchers at Massachusetts General Hospital and Karolinska Institutet in Sweden revealed the presence of widespread brain inflammation in patients diagnosed with fibromyalgia.3,4
Earlier research5 conducted at Karolinska Institutet also discovered high concentrations of cytokines (inflammatory proteins) in the cerebrospinal fluid, suggesting fibromyalgia patients have inflammation in their nervous system as well.6
The team at Massachusetts General Hospital, meanwhile, has previously shown that neural inflammation, and glial cell (immune cells) activation specifically, plays a role in chronic back pain. Animal studies have also offered evidence for the hypothesis that glial cell activation can be a cause of chronic pain in general.7
Here, they found that when glial cells in the cerebral cortex were activated, the more aggressive the activation, the greater the fatigue experienced by the patient. As reported by Medical Life Sciences:8
"The current study first assessed fibromyalgia symptoms in patients using a questionnaire. A PET tracer was then used, that is, a radioactive marker which binds a specific protein called translocator protein (TSPO) that is expressed at levels much above the normal in activated glial cells, namely, astrocytes and microglia …
[G]lial activation was found to be present at significantly higher levels in multiple brain areas in patients who had fibromyalgia than in controls. Glial cell activation causes inflammatory chemicals to be released, which cause the pain pathways to be more sensitive to pain, and promote fatigue …
One area showing higher TSPO binding in direct proportion to the self-reported level of fatigue was the cingulate gyrus, an area of the brain linked to emotional processing. Previous research has reported that this area is inflamed in chronic fatigue syndrome."
In related news, German researchers investigating inflammation mechanisms in the brain have found that as mice get older and regulation of inflammatory responses become increasingly impaired, they start losing brain cells.9
Interestingly, the cannabinoid receptor type 1 (CB1), which produces the "high" in response to tetrahydrocannabinol (THC) in marijuana, also helps regulate inflammatory reactions in your brain. In short, chronic brain inflammation is in part driven by the CB1 receptors' failure to respond. To understand how this works, you need to know a little bit about how microglial cells work.
Microglial cells are specialized immune cells found in your central nervous system, including your spinal cord and brain. These immune cells respond to bacteria and are responsible for clearing out malfunctioning nerve cells. They also signal and recruit other immune cells when needed and trigger the inflammatory response when necessary.
Problems arise when the inflammatory response becomes dysregulated and overactive. In the brain, the inflammation can easily damage healthy brain tissue. The "brake signal" that instructs glial cells to stop their inflammatory activity is endocannabinoids, and the endocannabinoids work by binding to certain receptors, including CB1 and cannabinoid receptor type 2 (CB2).
Curiously, microglial cells have virtually no CB1 and very few CB2 receptors, yet they still react to endocannabinoids. The present study was designed to investigate this puzzling riddle. As it turns out, there's a type of neuron that does contain a large number of CB1 receptors, and it appears that it is the CB1 receptors on these specific neurons that control microglial cell activity.
In other words, it appears microglial cells do not communicate with nerve cells directly; rather, they release endocannabinoids, which then bind to CB1 receptors found in nearby neurons. These neurons in turn communicate directly with other nerve cells. So, the brain's immune response is regulated in an indirect manner rather than a direct one.
Now, what happens with age is that your natural production of endocannabinoids decreases, which then leads to impaired immune response regulation and chronic inflammation. As noted by coauthor Dr. Andras Bilkei-Gorzo:10
"Since the neuronal CB1 receptors are no longer sufficiently activated, the glial cells are almost constantly in inflammatory mode. More regulatory neurons die as a result, so the immune response is less regulated and may become free-running."
Earlier research11 by this same team found that THC can help restore cognitive function in older brains, and the current study also hints at THC-containing cannabis may have valuable neuroprotective benefits in older people by quelling brain inflammation and preventing loss of brain cells. As the study was done on mice, further research is needed to confirm that the same mechanisms apply to humans, but it's compelling nonetheless.
Your diet can either promote or decrease inflammation. For example, foods that increase the inflammatory response in your body include:
Meanwhile, marine-based omega-3 fats have powerful anti-inflammatory effects, and are crucial for healthy brain function in general. Antioxidant-rich fruits and vegetables are also important for controlling inflammation, as is optimizing your vitamin D to a level of 60 to 80 ng/mL, ideally through sensible sun exposure.
In addition to anti-inflammatory and immune-boosting properties, vitamin D receptors appear in a wide variety of brain tissue, and researchers believe optimal vitamin D levels may enhance important chemicals in your brain and protect brain cells by increasing the effectiveness of glial cells that help nurse damaged neurons back to health.
A number of ubiquitous chemicals have also been implicated in inflammation, so if you struggle with fibromyalgia you'd be wise to take a close look at your choice of foods, household and personal care products. As mentioned earlier, getting enough high-quality sleep is another key treatment component for fibromyalgia.
Research12 published last year suggests ketogenic diets — which are high in healthy fats and low in net carbs — are a particularly powerful ally for suppressing brain inflammation, as ketones are powerful HDAC (histone deacetylase inhibitors) that suppress the primary NF-κB inflammatory pathway.
As explained by Medical Xpress,13 the defining moment of the study14 came when the team "identified a pivotal protein that links the diet to inflammatory genes, which, if blocked, could mirror the anti-inflammatory effects of ketogenic diets."
A ketogenic diet changes the way your body uses energy, converting your body from burning carbohydrates for energy to burning fat as your primary source of fuel. When your body is able to burn fat, your liver creates ketones, which burn more efficiently than carbs, thus creating far less reactive oxygen species and secondary free radicals that can damage your cellular and mitochondrial cell membranes, proteins and DNA.
Animals (rats) used in this study were found to have reduced inflammation when the researchers used a molecule called 2-deoxyglucose (2DG) to block glucose metabolism and induce a ketogenic state, similar to what would occur if you followed a ketogenic diet. By doing this, inflammation was brought down to levels near those found in controls.
Senior study author Dr. Raymond Swanson, a professor of neurology at UCSF and chief of the neurology service at the San Francisco Veterans Affairs Medical Center, commented on the results, saying:
"I was most surprised by the magnitude of this effect, because I thought ketogenic diets might help just a little bit. But when we got these big effects with 2DG, I thought wow, there's really something here.
The team further found that reduced glucose metabolism lowered a key barometer of energy metabolism — the NADH/NAD+ ratio — which in turn activated a protein called CtBP that acts to suppress activity of inflammatory genes."
The study also pointed out that a ketogenic diet may relieve pain via several mechanisms, similar to the ways it's known to help epilepsy.
"Like seizures, chronic pain is thought to involve increased excitability of neurons; for pain, this can involve peripheral and/or central neurons. Thus, there is some similarity of the underlying biology," the authors stated, adding:
"A major research focus should be on how metabolic interventions such as a ketogenic diet can ameliorate common, comorbid and difficult-to-treat conditions such as pain and inflammation."15
Eating a ketogenic diet doesn't have to be complicated or painful. My book "Fat for Fuel" presents a complete Mitochondrial Metabolic Therapy (MMT) program, complemented by an online course created in collaboration with nutritionist Miriam Kalamian, who specializes in nutritional ketosis.
The course, which consists of seven comprehensive lessons, teaches you the keys to fighting chronic disease and optimizing your health and longevity. In summary, the MMT diet is a cyclical ketogenic diet, high in healthy fats and fiber, low in net carbs with a moderate amount of protein.
The cyclical component is important, as long-term continuous ketosis has drawbacks that may actually undermine your health and longevity. One of the primary reasons to cycle in and out of ketosis is because the "metabolic magic" in the mitochondria actually occurs during the refeeding phase, not during the starvation phase.
Ideally, once you have established ketosis you cycle healthy carbs back in to about 100 to 150 grams on days when you do strength training. MMT has a number of really important health benefits, and may just be the U-turn you've been searching for if you're struggling with a chronic health condition. You can learn more by following the hyperlinks provided in the text above.
Since fibromyalgia is a chronic condition, it becomes emotionally challenging in addition to the physical challenges it imposes on your life. Having a game plan to deal with your emotional well-being is especially important if you suffer from any chronic disease.
If you have fibromyalgia, you might be able to trace it back to a triggering event, or you might not. Any traumatic experience has the potential to linger in your mind for a lifetime. You can have the perfect diet, the perfect exercise routine, and an ideal life; but if you have lingering unresolved emotional issues, you can still become very sick.
A tool that can help release this emotional sludge is the Emotional Freedom Techniques (EFT). If you are a regular reader of my newsletter, this won't be an unfamiliar term to you. EFT is a form of bioenergetic normalization. If you have fibromyalgia, this is something that is going to be extremely helpful. You can do this yourself, at home, and it takes just a few minutes to learn. For a demonstration, see the video above.
Chronic pain is a pervasive issue and fibromyalgia is a very common form. It is a chronic condition whose symptoms include muscle and tissue pain, fatigue, depression, and sleep disturbances.
Recent data suggests that central sensitization, in which neurons in your spinal cord become sensitized by inflammation or cell damage, may be involved in the way fibromyalgia sufferers process pain.
Certain chemicals in the foods you eat may trigger the release of neurotransmitters that heighten this sensitivity.
Although there have been only a handful of studies on diet and fibromyalgia, the following eating rules can’t hurt, and may help, when dealing with chronic pain.
Limit Sugar as Much as Possible. Increased insulin levels will typically dramatically worsen pain. So you will want to limit all sugars and this would typically include fresh fruit juices. Whole fresh fruit is the preferred method for consuming fruit products.
If you are overweight, have high blood pressure, high cholesterol or diabetes, you will also want to limit grains as much as possible as they are metabolized very similarly to sugars. This would also include organic unprocessed grains. Wheat and gluten grains are the top ones to avoid.
Eat fresh foods. Eating a diet of fresh foods, devoid of preservatives and additives, may ease symptoms triggered by coexisting conditions such as irritable bowel syndrome (IBS).
It’s also a good idea to buy organic food when possible, as it’s best to avoid pesticides and chemicals. However, fresh is best. So if you have to choose between local, fresh, non-organic and organic but wilting – go with fresh, and clean properly.
Avoid caffeine. Fibromyalgia is believed to be linked to an imbalance of brain chemicals that control mood, and it is often linked with inadequate sleep and fatigue. The temptation is to artificially and temporarily eliminate feelings of fatigue with stimulants like caffeine, but this approach does more harm than good in the long run. Though caffeine provides an initial boost of energy, it is no substitute for sleep, and is likely to keep you awake.
Try avoiding nightshade vegetables. Nightshade vegetables like tomatoes, potatoes, and eggplant may trigger arthritis and pain conditions in some people.
Be Careful with Your Fats. Animal based omega-3 fats like DHA and EPA have been touted as a heart-healthy food, and they may help with pain, as well. They can help reduce inflammation and improve brain function. At the same time, you want to eliminate all trans fat and fried foods, as these will promote inflammation.
Use yeast sparingly. Consuming yeast may also contribute to the growth of yeast fungus, which can contribute to pain.
Avoid pasteurized dairy. Many fibromyalgia sufferers have trouble digesting milk and dairy products. However, many find that raw dairy products, especially from grass fed organic sources, are well tolerated.
Cut down on carbs. About 90 percent of fibromyalgia patients have low adrenal functioning, which affects metabolism of carbohydrates and may lead to hypoglycemia.
Avoid aspartame. The artificial sweetener found in some diet sodas and many sugar-free sweets is part of a chemical group called excitotoxins, which activate neurons that can increase your sensitivity to pain.
Avoid additives. Food additives such as monosodium glutamate (MSG) often cause trouble for pain patients. MSG is an excitatory neurotransmitter that may stimulate pain receptors; glutamate levels in spinal fluid have been shown to correlate with pain levels in fibromyalgia patients.
Stay away from junk food. Limit or eliminate fast food, candy, and vending-machine products. In addition to contributing to weight gain and the development of unhealthy eating habits, these diet-wreckers may also irritate your muscles, disrupt your sleep, and compromise your immune system.
Researchers have detected abnormalities in the brains of people with fibromyalgia, a chronic condition whose symptoms include muscle pain and fatigue.
Electromagnetic Hypersensitivity Syndrome (EHS) is a condition in which people are highly sensitive to electromagnetic fields. In an area such as a wireless hotspot, they experience pain or other symptoms.
People with EHS experience a variety of symptoms including headache, fatigue, nausea, burning and itchy skin, and muscle aches. These symptoms are subjective and vary between individuals, which makes the condition difficult to study, and has left experts divided about the validity of such claims.
More than 30 studies have been conducted to determine what link the condition has to exposure to electromagnetic fields from sources such as radar dishes, mobile phone signals and, Wi-Fi hotspots.

Reaching puberty is a rite of passage that we've all been through, but children are now reaching it earlier than ever before, and while precocious puberty in girls has received most of the attention, we now know the trend applies to boys as well.
In the 19th century, the onset of menstruation in girls occurred around the age of 15. Now the average age of the first period is around 12. Some girls develop breasts as early as age seven1 .
According to a recent study in the journal Pediatrics2, boys are now beginning sexual development anywhere from six months to two years earlier than the medically accepted standard based on previous studies.
African-American boys were found to hit the onset of puberty the soonest, starting around the age of nine. Caucasian and Hispanic boys begin developing around the age of 10.
"The causes and public health implications of this apparent shift in US boys to a lower age of onset for the development of secondary sexual characteristics in US boys needs further exploration," the authors write.
Indeed, while some may shrug off the trend of earlier maturation, it's actually pretty significant, as it can affect both physical and psychological health in a number of ways, including raising the future risk for hormone-related cancers. Girls who enter puberty earlier are at an increased risk of breast cancer, for example, due to the early rise in estrogen.
The trend also raises serious questions about environmental factors spurring this development. Lead researcher Marcia Herman-Giddens told CNN Health3:
"The changes are too fast. Genetics take maybe hundreds, thousands of years. You have to look at something in the environment. That would include everything from (a lack of) exercise to junk food to TV to chemicals."
Scientists have brought forth a number of potential explanations for the rising rates of early puberty, but one that deserves special attention is environmental chemicals, and particularly xeno-estrogens, i.e. estrogen-mimicking chemicals. These compounds behave like steroid hormones and can alter the timing of puberty, and affect disease risk throughout life.
In adults, xeno-estrogens have been linked to decreased sperm quality, stimulation of mammary gland development in men, disrupted reproductive cycles and ovarian dysfunction, obesity, cancer and heart disease, among numerous other health problems.
We're surrounded by hormone-disrupting chemicals these days, many of which are plasticizers. Bisphenol A (BPA) for example, is an industrial petrochemical that acts as a synthetic estrogen, and can be found plastics and tin can linings, in dental sealants, and on cash-register receipts. Three years ago, laboratory tests commissioned by the Environmental Working Group (EWG) detected BPA in the umbilical cord blood of 90 percent of newborn infants tested -- along with more than 230 other chemicals!
In September 2010, Canada declared BPA a toxic substance, but to date no other country has followed suit, although BPA has been banned in baby bottles in Canada, Europe and the United States. Frustratingly, the US FDA has denied the request to ban BPA, however many American companies have voluntarily removed the chemical from their products, in response to consumer demand. So, if you check around, you can find a lot of BPA-free products.
However, buyer beware, as it recently came to light that some companies are simply replacing the offending BPA with another less known but equally toxic chemical called bisphenol-S (BPS)! Not only does BPS appear to have similar hormone-mimicking characteristics to BPA, but research suggests it is actually significantly less biodegradable, and more heat-stable and photo-resistant, than BPA.
Beside BPA and BPS, other top offenders you should be aware of, and watch out for, include:
Phthalates, a group of industrial chemicals used to make plastics like polyvinyl chloride (PVC) more flexible and resilient. They're also one of the most pervasive of the endocrine disrupters, found in everything from processed food packaging and shower curtains to detergents, toys and beauty products like nail polish, hair spray, shampoo, deodorants, and fragrances. Exposure to phthalates can lead to incomplete testicular descent in fetuses, reduced sperm counts, testicular atrophy or structural abnormality and inflammation in newborns. Fluoride, which is added to the majority of public water supplies in the United States. Research has shown that animals treated with fluoride had lower levels of circulating melatonin, as reflected by reduced levels of melatonin metabolites in the animals' urine. This reduced level of circulating melatonin was accompanied -- as might be expected -- by an earlier onset of puberty in the fluoride-treated female animals. Perfluorooctanoic acid (PFOA), a likely carcinogen found in grease- and water-resistant coatings and non-stick cookware. Methoxychlor and Vinclozin, an insecticide and a fungicide respectively, have been found to cause changes to male mice born for as many as four subsequent generations after the initial exposure. Nonylphenol ethoxylates (NPEs). Known to be potent endocrine disrupters, these chemicals affect gene expression by turning on or off certain genes, and interfere with the way your glandular system works. Bovine growth hormones (rBGH) commonly added to commercial dairy have been implicated as a contributor to premature adolescence. MSG, a food additive that's been linked to reduced fertility. Non-fermented soy products, which are loaded with hormone-like substances. DDE (a breakdown product of the pesticide DDT) PCBs
Recent research has also confirmed the existence of a previously unknown class of cancer-causing estrogen-mimicking compounds: "metalloestrogens." The following metals, which are added to thousands of consumer products, including vaccines, have been identified as being capable of binding to cellular estrogen receptors and then mimicking the actions of physiological estrogens:4
Aluminum Antimony Arsenite Barium Cadmium Chromium Cobalt Copper Lead Mercury Nickel Selenite Tin Vanadate
While young girls and boys may show obvious signs of exposure to hormone-disrupting substances via early puberty, other signals are more insidious and may not show up until a disease is already present. You can cut back on your family's exposure to these dangerous chemicals by following these 12 guidelines. Pregnant women and women who may become pregnant should pay particular attention to reducing their exposure as much as possible to protect the health of their unborn baby:
- Eat whole, preferably organic, produce and free-range, organic meats to reduce your exposure to added hormones, pesticides and fertilizers. Also avoid milk and other dairy products that contain the genetically engineered recombinant bovine growth hormone (rBGH or rBST)
- Eat mostly raw, fresh foods. Processed, prepackaged foods (of all kinds) are a major source of soy and chemicals such as BPA and phthalates.
- Store your food and beverages in glass rather than plastic, and avoid using plastic wrap and canned foods (which are often lined with BPA-containing liners).
- Use glass baby bottles and BPA-free sippy cups for your little ones.
- Make sure your baby's toys are BPA-free, such as pacifiers, teething rings and anything your child may be prone to suck on.
- Only use natural cleaning products in your home to avoid phthalates.
- Switch over to natural brands of toiletries such as shampoo, toothpaste, antiperspirants and cosmetics. The Environmental Working Group's Skin Deep Database5 is a great resource for finding personal care products that are free of phthalates, parabens and other potentially dangerous chemicals.
- Avoid using artificial air fresheners, dryer sheets, fabric softeners or other synthetic fragrances.
- Replace your non-stick pots and pans with ceramic or glass cookware.
- When redoing your home, look for "green," toxin-free alternatives in lieu of regular paint and vinyl floor coverings.
- Replace your vinyl shower curtain with one made of fabric.
- Avoid non-fermented soy, especially if you're pregnant. Also, never use soy-based infant formula.

Reaching puberty is a rite of passage that we've all been through, but children nowadays are reaching it earlier than ever before -- a trend that has both health experts and parents alarmed.
Precocious puberty, which is the appearance of secondary sex characteristics like pubic hair or breast growth before age 8, or the onset of menarche before age 9, impacts at least 1 in 5,000 U.S. children, and the rate is on the rise.1
Even in the last three decades, children (particularly girls) are maturing at younger and younger ages (precocious puberty is 10 times more common in girls than in boys).
In the 19th century the onset of menstruation occurred around the age of 15. Now the average age of the first period, or menarche, is around 12. The time during and before puberty is one of rapid development and change, which is why even months matter when it comes to first menstruation. Before menstruation, girls will show beginning signs of development, such as breast "budding" and growth of pubic hair.
These signs are now becoming unsettlingly common among 7-, 8- and 9-year-old girls, to the extent that many health care providers, rather than labeling these children with a diagnosis that something is wrong, have simply changed the definition of what's normal... but is it really "normal" for girls to mature at such a young age?
There are more questions than answers in the case of precocious puberty, but what is certain is that girls are developing earlier than they have even 10, 20 or 30 years ago.
One study in the journal Pediatrics revealed that by age 7, 10 percent of white girls, 23 percent of black girls, 15 percent of Hispanic girls and 2 percent of Asian girls had started developing breasts, with researchers noting:2
"The proportion of girls who had breast development at ages 7 and 8 years, particularly among white girls, is greater than that reported from studies of girls who were born 10 to 30 years earlier."
Early puberty can set the stage for emotional and behavioral problems, and is linked to lower self-esteem, depression, eating disorders, alcohol use, earlier loss of virginity, more sexual partners and increased risk of sexually transmitted diseases. There is also evidence that suggests these girls are at increased risk of diabetes, heart disease and other cardiovascular diseases, as well as cancer, later in life.
Scientists have brought forth a number of potential explanations for the rising rates of early puberty, but one that deserves special attention is environmental chemicals, and particularly estrogen-mimicking, "gender-bending" chemicals that easily leach out of the products that contain them, contaminating everything they touch, including food and beverages.
As the featured New York Times article reported:
" ...animal studies show that the exposure to some environmental chemicals can cause bodies to mature early. Of particular concern are endocrine-disrupters, like "xeno-estrogens" or estrogen mimics. These compounds behave like steroid hormones and can alter puberty timing.
For obvious ethical reasons, scientists cannot perform controlled studies proving the direct impact of these chemicals on children, so researchers instead look for so-called "natural experiments," one of which occurred in 1973 in Michigan, when cattle were accidentally fed grain contaminated with an estrogen-mimicking chemical, the flame retardant PBB.
The daughters born to the pregnant women who ate the PBB-laced meat and drank the PBB-laced milk started menstruating significantly earlier than their peers."
This is an extreme case, but the truth is we are all part of a "secret experiment" of sorts, because hormone-disrupting chemicals are all around us. Bisphenol A (BPA), an industrial petrochemical that acts as a synthetic estrogen, is found in our plastics and our tin can linings, in dental sealants and on cash-register receipts. Laboratory tests commissioned by the Environmental Working Group (EWG) detected BPA in the umbilical cord blood of 90 percent of newborn infants tested -- along with more than 230 other chemicals. As written in the New York Times:
"One concern, among parents and researchers, is the effect of simultaneous exposures to many estrogen-mimics, including the compound BPA, which is ubiquitous."
No one knows what happens when a developing fetus or young child is exposed to hundreds of chemicals, many of which mimic your body's natural hormones and can trigger major changes in your body even as an adult, let along during the most rapid and vulnerable periods of development (in utero and as a young child).
BPA is, unfortunately, but one example. Others include phthalates, a group of industrial chemicals used to make plastics like polyvinyl chloride (PVC) more flexible and resilient. They're also one of the most pervasive of the endocrine disrupters, found in everything from processed food packaging and shower curtains to detergents, toys and beauty products like nail polish, hair spray, shampoo, deodorants, and fragrances.
Other environmental chemicals like PCBs and DDE (a breakdown product of the pesticide DDT) may also be associated with early sexual development in girls. Both DDE and PCBs are known to mimic, or interfere with, sex hormones.
Perfluorooctanoic acid (PFOA), found in non-stick cookware, also falls into this dangerous category, as does fluoride, which is added to the majority of public water supplies in the United States. Research showed that animals treated with fluoride had lower levels of circulating melatonin, as reflected by reduced levels of melatonin metabolites in the animals' urine. This reduced level of circulating melatonin was accompanied -- as might be expected -- by an earlier onset of puberty in the fluoride-treated female animals.
If a chemical is capable of influencing the rate of your reproductive development, it stands to reason that it would be capable of influencing other hormone-sensitive growth processes as well, and this is indeed the case.
For instance, new research has detected the presence of paraben esters in 99 percent of breast cancer tissues sampled.3 Parabens are chemicals with estrogen-like properties, and estrogen is one of the hormones involved in not only puberty but also the development of breast cancer. They are widely used in household products such as:
|
✓ Deodorants and antiperspirants |
✓ Shampoos and conditioners |
✓ Shaving gel |
✓ Toothpaste |
|
✓ Lotions and sunscreens |
✓ Make-up / cosmetics |
✓ Pharmaceutical drugs |
✓ Food additives |
Recent research has also confirmed the existence of a previously unknown class of cancer-causing estrogen-mimicking compounds: metals. Yes, a broad range of metals have been shown to act as "metalloestrogens" with the potential to add to the estrogenic burden of the human body, thereby increasing the risk of breast cancer and also possibly early puberty. The following metals, which are added to thousands of consumer products, including vaccines, have been identified as being capable of binding to cellular estrogen receptors and then mimicking the actions of physiological estrogens:4
|
✓ Aluminum |
✓ Antimony |
✓ Arsenite |
✓ Barium |
✓ Cadmium |
✓ Chromium |
✓ Cobalt |
|
✓ Copper |
✓ Lead |
✓ Mercury |
✓ Nickel |
✓ Selenite |
✓ Tin |
✓ Vanadate |
Data from a long-running British health survey, meanwhile, has shown that if you have high levels of the chemical BPA in your urine, you may be at an increased risk of heart disease. Some of the greatest concern surrounds early-life, in utero exposure to BPA, which can lead to chromosomal errors in your developing fetus, causing spontaneous miscarriages and genetic damage. But evidence is also very strong showing these chemicals are influencing adults and children, too, and leading to decreased sperm quality, early puberty, stimulation of mammary gland development, disrupted reproductive cycles and ovarian dysfunction, obesity, cancer and heart disease, among numerous other health problems.
While young girls may show obvious signs of exposure to hormone-disrupting substances via early puberty, other signals are more insidious and may not show up until a disease is already present. Here are 11 measures you can implement right away to help protect yourself and your children from common toxic substances that could cause precocious puberty and other long-term health problems:
Theo Colburn's book Our Stolen Future is a great source for further investigation as it identifies the numerous ways in which environmental pollutants are disrupting human reproductive patterns. I believe it is one of the best resources on this topic and highly recommend it.
It has been suggested that girls who live closer to the equator start puberty at a later age than girls who live in Northern regions. Since this indicates a potential connection with sun exposure, researchers decided to investigate whether vitamin D was, in fact, related. Upon measuring vitamin D levels in 242 girls aged 5-12, researchers from the University of Michigan School of Public Health found that those who were deficient were twice as likely to start menstruation during the study period as those with higher levels.5
Specifically, among the vitamin-D-deficient girls, 57 percent started their period during the study, compared to 23 percent with adequate vitamin D. However, researchers defined adequate vitamin D as ≥ 30 ng/mL, which is actually still a deficiency state! For optimal health, vitamin D levels should be a minimum of 50 ng/mL, which means the number of vitamin-D-deficient girls with early puberty was probably much higher than the study reported.
The earlier you enter puberty, the longer you're exposed to elevated levels of the female hormone estrogen, which is a risk factor for certain cancers such as breast cancer. This has been the primary "link" between early puberty and cancer that has been explored, but it's important to understand that vitamin D deficiency is also a major risk factor for cancer, heart disease and many other diseases. So it could be that some of the increased risks that come from early puberty are linked to low vitamin D levels.
Obesity (which exposes girls to more estrogen because estrogen is both stored and produced in fat tissue) is another likely factor in early puberty. The New York Times reported:
"As Robert Lustig, a professor of clinical pediatrics at the University of California, San Francisco's Benioff Children's Hospital, explains, fatter girls have higher levels of the hormone leptin, which can lead to early puberty, which leads to higher estrogen levels, which leads to greater insulin resistance, causing girls to have yet more fat tissue, more leptin and more estrogen, the cycle feeding on itself, until their bodies physically mature."
As for stress, this, too, has been linked to early puberty, with girls whose parents divorced when they were between 3- and 8-years-old significantly more likely to experience precocious puberty. "Evolutionary psychology offers a theory," the New York Times reports. "A stressful childhood inclines a body toward early reproduction; if life is hard, best to mature young. But such theories are tough to prove." Interestingly, in addition to avoiding environmental chemicals, obesity and stress, and optimizing your vitamin D, regular exercise appears to be one of the best known ways to help prevent early puberty.
As plastic ages or is exposed to heat or stress, it can release trace amounts of some of its ingredients. Of particular concern are bisphenol-a (BPA), used to strengthen some plastics, and phthalates, used to soften others.
More than 80 percent of schools in America use toxic pesticides as a preventative measure, whether it‘s needed or not.
Mark Lame, an entomologist and professor at Indiana University‘s School of Public and Environmental Affairs, believes this is an entirely unnecessary practice that carries more risks than benefits to students and faculty.
The most widely used pesticides are, in fact, nerve poisons. They cause uncontrolled nerve firing, and disrupt the delicate hormone systems.
The link between pesticide exposure and health problems in children is already well established. Research has connected these endocrine-disrupting pesticides to health problems such as ADHD, autism, and infertility -- all of which are on the rise.
Professor Lame says pest problems are better managed through an integrated approach -- by preventing the conditions that attract pests into school facilities in the first place.
Lame serves as a consultant for schools around the country, helping them reduce the toxic load by implementing his Integrated Pest Management (IPM) process.

More than three decades of scientific research suggests that repeatedly telling children that they are especially smart or talented leaves them vulnerable to failure, and fearful of challenges.
Children raised this way develop an implicit belief that intelligence is innate and fixed, making striving to learn seem less important than seeming smart; challenges, mistakes, and effort become threats to their ego rather than opportunities to improve.
However, teaching children to have a “growth mind-set,” which encourages effort rather than on intelligence or talent, helps make them into high achievers in school and in life. This results in “mastery-oriented” children who tend to think that intelligence is malleable and can be developed through education and hard work.
This can be done by telling stories about achievements that result from hard work. Talking about math geniuses who were born that way puts students in a fixed mind-set, but descriptions of great mathematicians who developed amazing skills over time creates a growth mind-set.
