Perils of Plastic: Chemicals in plastics and other products seem harmless, but mounting evidence links them to health problems -- and Washington lacks the power to protect us
TIME magazine (issue: April 12, 2010) featured a special report entitled 'The Perils of Plastic' HERE (or HERE or HERE ). Below are are choice quotes I like by reporter Bryan Walsh [including my emphasis].
Prior Nephropal from Dr. Tourgeman MD: Bisphenol A (BPA) lowers adiponectin, associated with insulin resistance, weight gain, fat gain, twisted testosterone metabolism, lower sperm count
Happy Earth Day... *contemptuous sigh*
Does This Affect Adrenals? Thyroids?
Possibly? Any hormone disruption and dysregulation at the cellular or macro-biology level affects adrenals. Heavy metals are implicated in the formation of free T4 to rT3, which is a useless form of thyroid hormone and not selenium or iodine-dependent (unlike activation of T4 to T3).
MOOBIES: high DHT, high Estrone, high Prolactin, low vitamin D
Boys becoming physically and metabolically like girls... that's called MOOBIES, higher prolactin, higher estrogen expression, erectile dysfunction, hypogonadism, testicular failure, andropause. Pollutants are highly associated with delayed maturation in adolescents and significantly interrupted hormone pathways. (Diagram, courtesy of health-spy.com )
"In 2002, the Centre for Environment and Health in Flanders, Belgium started a human biomonitoring program. For 1679 adolescents, residing in nine study areas with differing pollution pressure, hormone levels and the degree of sexual maturation were measured. Possible confounding effects of lifestyle and personal characteristics were taken into account. Participants from the nine different study areas had significantly different levels of sex hormones (total and free testosterone, oestradiol, aromatase, luteinizing hormone) and the thyroid hormone free triiodothyronine, after correction for confounders. Significantly higher hormone concentrations were measured in samples from participants residing in the area around the waste incinerators, while significantly lower values were found in participants residing in the Albert Canal zone with chemical industry."2
PaleoHacks Forum Thread: Middle-Aged Male Gynecomastia, aka 'Moobs'
Check out this thread HERE . Thank you Dexter -- forgot about my comments! Jae and Kevin Teague covered all the bases. Good job, boys! Eat paleo, do HIIT (to raise T), lose body fat (reduces DHT conversion), take vitamin D (lowers prolactin, raises T), eat fat, eat low carb, etc. This works. Current conventional medicine treatment includes... surgical options (moob-ectomy), aromatase inhibitors, or Tamoxifen (estrogen blocker): HERE .
Males: Avoid Xeno-Estrogens
Xenobiotics are found in food, herbs and pharmaceuticals. These are chemical structures which our bodies need to metabolize and eliminate via our P450 enzyme systems in the liver and other tissues. Many are fat-soluble and require a healthy liver (phase 2), gallbladder and biliary system to conjugate and eliminate from the entero-hepatic cycling that occurs in our gut. Our body has evolved to conserve and 'recycle' the 'good stuff' from our skin and oral exposures like cholesterol, vitamins, steroid derivatives, endorphins, sex steroids, fatty acids and other constituents. Unfortunately, toxins get recycled too.
The best is to avoid toxins.
Phytoestrogens are plant-derived xeno-estrogens; they are everywhere but some phytoestrogens have higher biological potency. Both plants and animals utilize estrogen phylogenically. Xenoestrogens vary in their effects. Some may protect against estrogen and xenoestrogen-induced breast cancer and other cancers but the downside for men are the ubiquitious estrogenic effects including breast tissue growth and penile reducing effects.
Some bind estrogen and progesterone receptors and potently or partially enact the below or some combination--inhibition of estrogen receptors (block)
--activation of estrogen receptors
--inhibition of progesterone (block)
--activation of progesterone
--inhibition of androgens (block)
Estrogen is producted by men and women (in the adrenals in both genders and ovaries in women). It feminizes however our understanding of estrogen has greatly expanded to include countless brain, neural and immunity related activities. Men need some, but not a lot. Women, we need a lot comparatively and it protects against Alzheimer's, infections and looking wrinkled. Important.
Progesterone is made by both men and women (again in the adrenals of both genders and ovaries of women). Progesterone has some androgenic action for fat burning, muscle building, mood, immunity, neuroprotective (give me 'P' if I ever have a cerebral edema) and well being. Progesterone is the MAIN hormone in pregnancy. It sustains the pregnancy and allows for exponential tissue growth. At high levels, tissues and collagen relax and cortisol and insulin go up (providing even sustained glucose supplies for the fetus). Women make ~20 mg/d of 'P' but during pregnancy, fetal adrenal and maternal production increase to ~200 mg/d. Fetal adrenal glands are 10-20x that of an adult. It shrinks after birth and post-natally.
Many xeno-estrogens block progesterone and lead to anti-adrogenic actions. In women, pomegranate, like RU486, was once used in ancient Greek as an abortifacient and to induce uterine contractions.
Below are known to raise estrogen effects and lead to gynecomastia should be limited in exposure by mouth, skin, or breath if you are trying to limit your moobie growth--soy SOY SOY (!OY)
--BEER (hops contains high phytoestrogens)
-- whisky in oak (per Paleo hacks)
--omega-6 (peanuts, sunflower, cottonseed, safflower oils) which increase inflammatory steroidogenesis including cortisol which raises DHT and endogenous estrogens
--pomegranate, red clover, yucca
--topical use of tea tree oil, lavender oil
--excessive caffeine (raises cortisol and depletes adrenals too; fibrocystic breasts)
Synthetic xeno-estrogens, unlike some of the natural, plant-derived compounds that exist in food and plants, are chemicals and therefore not recognized by our mammalian receptors for appropriate metabolism and elimination. Worse, they are stored in the fat tissues with extremely long biological half-lives. Synthetic xeno-estrogens and xeno-progestins may take weeks, months or decades to be excreted. Birth control, Provera (medroxyprogesterone), Depo-Provera, plastics, BPA, environmental pollutants are in this class.
Bisphenol A Elevated in Women with PCOS Compared With Non-PCOS Women
Girls. We are affected too. PCOS is the female version of moobies... females veering toward male dimorphic expression (hirsutism/facial hair, higher androgens (T, DHT), male pattern baldness/alopecia, masculinization, low estriol/estradiol, PMS, ovarian failure, sterility, early menopause). Takeuchi et al discuss the dose-related bisphenol A effect and how related to degree of hormonal dysregulation in women with PCOS. Obese women without PCOS also showed higher BPA levels compared to non-obese without PCOS. Not surprising. BPA, mercury and other pollutants have been shown to increase insulin resistance and body fat.
This study was performed to investigate the serum levels of bisphenol A (BPA), an endocrine disruptor, in women with ovarian dysfunction and obesity. Fasting serum samples were obtained from 19 non-obese and 7 obese women with normal menstrual cycles: 7 patients with hyperprolactinemia, 21 patients with hypothalamic amenorrhea, and 13 non-obese and 6 obese patients with polycystic ovary syndrome (PCOS). BPA was measured by an enzyme-linked immunosorbent assay. BPA was detected in all human sera. Serum BPA concentrations were significantly higher in both non-obese and obese women with polycystic ovary syndrome (1.05 +/- 0.10 ng/ml, 1.17 +/- 0.16 ng/ml; p < 0.05, respectively) and obese normal women (1.04 +/- 0.09 ng/ml, p < 0.05) compared with those in non-obese normal women (0.71 +/- 0.09 ng/ml). There was no difference among women with hyperprolactinemia, women with hypothalamic amenorrhea, and non-obese normal women. There were significant positive correlations between serum BPA and total testosterone (r = 0.391, p < 0.001), free testosterone (r = 0.504, p < 0.001), androstenedione (r = 0.684, p < 0.001), and DHEAS (r = 0.514, p < 0.001) concentrations in all subjects. These findings show that there is a strong relationship between serum BPA and androgen concentrations, speculatively due to the effect of androgen on the metabolism of BPA.
Boys and Girls: Avoid BPA and other Xenoestrogens
I've had to deal with synthetic progestin toxicity for the last 2 years. There was not that much I could do but what helped the most in excreting the xenobiotic I found was the below. Whenever I gained body fat (holiday eating, stress, stopping vitamin D, etc), I found the symptoms I was having were exacerbated and acutely worsened. When I dropped body fat with exercise and yoga, then the symptoms curbed down again. Body fat for me has been the biggest factor I can vary which affected symptoms and the control symptoms.
--exercising frequently to lower body fat and control insulin/cortisol/leptin (cardio 50-70% max HR four to seven hours per week) (leptin RAISES aromatase)
--HIIT 1-2x/wk (NONE unless rested/relaxed; don't over do it;BSS rocks)
--yoga, massage (relieves stress, prevents injury, resets adrenals which produce cortisol and hormones, moves lymph and circulation)
--hypocaloric high protein diet with carb cycling (900-1200 kcal/d -- I'm ~120 lbs)
--fiber -- this removes bile acid conjugates (metamucil, non-starchy vegetables dominated diet, cruciferous, seaweed, leeks, green apples, etc)
--fat (coconut milk, grassfed meat eggs, etc), omega-3, flaxseed oil
--cilantro, garlic (helps glutathione which uncouples toxins from binding), silymarin (helps glutathione and keeps the liver strong), NAC (glutathione precursor), Vitamin C, tocopherols/ tocotrienols, chlorella (antioxidant and removes toxins), coenzyme Q10 (tags proteins and DNA for proper disposal or recycline), pycnogenol (antioxidant and removes toxins), trace minerals (metal detox)
--normal bile conjugation, synthesis and elimination (fermented foods, digestive enzymes, indole-3-carbinol/DIM, taurine/glycine (and/or raw grassfed or uncontaminated-seafood), egg yolks, low carb/high sat fat diet) (when my adrenals were shot x6-12 months, I couldn't tolerate much taurine which made me dizzy and ataxic; need a modicum of decent adrenals)
--GUT, thyroid, adrenal and vitamin D optimization (affect temperature and metabolism of enzymes, P450 detox enzymes, liver, steroidogenesis and neutrotransmitters)
