BPA substitute Tritan found to cause estrogenic activity: Migration of plasticisers from Tritan ™ and polycarbonate bottles and toxicological evaluation Estrogenic chemicals often leach from BPA-free plastic products that are replacements for BPA-containing polycarbonate products Chemicals having estrogenic activity can be released from some bisphenol A-free, hard and clear, thermoplastic resins UPDATE: This search at […]

The math behind the ocean/human plastic contamination concentration
Geek note: mass and weight are not the same thing. Mass is a measurement of how much matter is in something. Weight is a measure of the pull of gravity on mass. That’s why an object on the moon weighs 1/6 that of that same object on the earth.(And why astronauts on the space station […]
Radiation, Ebola, lice, bedbugs, ticks & BPA: No matter how hard you try, you can’t avoid plastic chemicals
Risk = concentration + frequency. Radiation, Ebola, lice, bedbugs ticks and Bisphenol A (and other plastic chemicals) have a fair amount in common. Fortunately, you can choose to avoid five of those six, but the third gets forced upon you every minute of every day. First, they are all alike because the damage they can […]
Your cells: Complicated, vulnerable to disruption by BPA and other chemicals
Complicated and Fragile Another reason that such small concentrations can affect you is that they operate inside of tiny cells that are complicated and fragile. And that makes it a matter both of scale and potency. The cells in your body are like a well-run city maintained with carefully balanced mechanisms that produce energy, get […]
Serious flaws found in Lancet study “debunking myth” of healthy moderate alcohol consumption
By Lewis Perdue Co-Principal Investigator Stealth Syndromes Human Study Co-founder, Stealth Syndromes Project Chairman, Center for Research on Environmental Chemicals in Humans NOTE: You may right-click all images to view a larger version The recent Lancet study that found no cardio-protective benefits of moderate alcohol consumption is marred by substantial problems which raise serious concerns […]
The Mendelian Randomization by Millwood et al.: Observations and Expressions of Concern
By Lewis Perdue Co-Principal Investigator Stealth Syndromes Human Study Co-founder, Stealth Syndromes Project Chairman, Center for Research on Environmental Chemicals in Humans The recent population study of adults in China that found no cardio-protective benefits of moderate alcohol consumption should be re-examined in the context of methodological and confounding factors not addressed in the published […]
Two criteria for the evolutionary selection of ALDH2*2 other than as a protection against alcohol disorder
Adaptive Genetic Variation and Population Differences Author links open overlay panelChao-QiangLai https://doi.org/10.1016/B978-0-12-398397-8.00018-6 “It is unlikely that the high frequency of these risk alleles was under recent selection by alcoholism. “Goldman and Enoch93 proposed two possible types of selection. First, mycotoxins (aflatoxins, in particular), which can cause hepatic disease and cancer, are commonly present in moldy […]
Paleogenetics looks at the origins of the ability to metabolize alcohol
Humans have been consuming ethyl alcohol — ethanol — for millions of years. Indeed, the ability to consume alcohol may have shaped primate evolution. Humans have this ability because, in addition to obvious beverage sources, alcohol is present in many common foods such as bread and other bakery products, fruit and fruit juices (Gorgus, et, […]
Sources for Under-Reporting of Alcohol Consumption
Sources, Under-Reporting Underreporting in alcohol surveys: whose drinking is underestimated? Drinking pattern is more strongly associated with under-reporting of alcohol consumption than socio-demographic factors: evidence from a mixed-methods study Estimating under- and over-reporting of drinking in national surveys of alcohol consumption: Identification of consistent biases across four English-speaking countries How is alcohol consumption affected if […]
All moderate alcohol consumption studies are “all over the charts”
All moderate alcohol consumption studies are “all over the charts” because they are epidemiological and plagued by confounding factors no matter how hard investigators work to control for those. Epidemiology is a correlative method that cannot conclude causation. This is true even with newer statistical techniques such as Mendelian Randomization.For an extended examination of the […]
