Patrick Tims via NaturalHealth365 – The pervasive presence of this toxic substance in everyday items creates a significant health threat. BPA (Bisphenol A), a colorless and soluble chemical, is likely within reach right now, as it’s commonly used in plastics and embedded in so many consumer products. The pervasive presence of this toxic substance in everyday items creates a significant health threat. A recent study in The Journal of Hazardous Materials links early BPA exposure to a higher risk of serious health issues, including type 2 diabetes, obesity, stroke, and heart disease. This early exposure can disrupt hormonal balance, leading to long-term consequences that extend well into adulthood. BPA is found in the most common consumer products BPA is found in food packaging, processed foods, consumer products, and even industrial items, making it nearly impossible to avoid. As an endocrine disruptor, this chemical alters hormones, increasing the risk of chronic diseases over time. Unfortunately, because it’s so widespread, exposure often begins early in life, during those crucial formative years. Research shows that BPA exposure in childhood sets the stage for cardiometabolic health issues that persist into adolescence and adulthood. By damaging blood vessels and the heart, BPA compromises the body’s ability to regulate weight, maintain healthy blood sugar levels, and process nutrients effectively, leading to long-term health challenges. A closer look at the BPA research that’s shaking up the health industry To better understand BPA exposure, the research team used direct and indirect methods to predict its impact. They cross-referenced food consumption diaries with demographic data, urine samples, and blood biomarkers, adjusting for key variables like overall energy intake. Participants were asked to provide detailed information about their food and drink choices, including when and where they consumed them and specifics like preparation methods, portion sizes, brand, and packaging. Because BPA exits the body quickly, 24-hour urine samples were analyzed to more accurately measure daily exposure. The team followed up at 4-, 7-, and 10-year intervals, with a 13-year follow-up for adolescents, to track the long-term effects of early exposure. BPA causes a multitude of health problems most aren’t aware of According to the study, BPA exposure is linked to increased fat mass, particularly around the waist, leading to a higher risk of abdominal obesity. This type of fat accumulation is especially concerning, as it’s associated with a greater risk of metabolic conditions like type 2 diabetes and cardiovascular disease. Additionally, BPA exposure can significantly impact insulin function, raising insulin resistance and levels in the body. This disrupts the body’s ability to regulate blood sugar effectively, which, over time, can lead to chronic conditions such as insulin resistance and type 2 diabetes. The compound’s effects on metabolism can be subtle but serious, impacting long-term health in often overlooked ways. Tips to reduce BPA exposure If you have a child, or teen at home, reducing their exposure to BPA is essential. While BPA is widespread in consumer products, there are simple actions you can take to limit its presence in your home. When shopping, avoid processed foods and choose organic options instead. Once home, transfer food from plastic packaging into BPA-free containers, such as glass or stainless steel. To further reduce BPA exposure, minimize the use of plastics whenever possible. Opt for bulk items instead of those packaged in plastic and choose products with plastic-free packaging. By making these small changes, you can significantly lower your family’s BPA exposure and support healthier long-term outcomes.

Can We Safely Use Melamine Dishes and Polyamide Plastic Utensils?

The AHA! Team — Fri, 08 Nov 2024 06:19:29 +0000

Michael Greger M.D. FACLM via Nutrition Facts – Melamine is used to make a variety of hard plastic “food contact items such as cups, plates, bowls, and utensils because they are dishwasher safe, inexpensive, and durable.” I recommend glass, ceramic, porcelain, or stainless steel tableware and wooden or stainless steel cooking utensils. Melamine is used to make a variety of hard plastic “food contact items such as cups, plates, bowls, and utensils because they are dishwasher safe, inexpensive, and durable.” If that word sounds familiar, it may be because melamine has also been added illegally to protein products to game the system to make it appear that “food commodities” like pet food contain more protein than they actually do. By 2007, more than a thousand potentially contaminated pet food products were recalled By 2007, more than a thousand potentially contaminated pet food products were recalled after “the chemical was found to be a contaminant in wheat gluten used in those products,” but not before it caused disease and death in pets throughout North America. “It is presumed that melamine was intentionally added by suppliers in China to falsely elevate the measured protein content and, hence, the monetary value of these products.” The pet food scandal was just the writing on the wall. The following year, “melamine was discovered to be the cause of an outbreak of urinary tract stones and renal failure” (kidney stones and kidney failure), affecting hundreds of thousands of infants and young children throughout China. “Investigations revealed that the compound was added illegally to powdered milk and baby formulas to falsify protein content.” As I discuss in my video Are Melamine Dishes and Polyamide Plastic Utensils Safe?, in the United States, you can find it in food packaging and sneaking its way into animal feed. However, those using melamine dishware can be exposed directly, as it migrates straight into the food upon exposure to heat. In fact, “cooking spoons and crockery made of melamine resin are not suited for microwaves and cooking,” according to food safety authorities. Okay, but what if you never cook with it, fry with it, or microwave it? What if you just use melamine to eat out of? In “A Crossover Study of Noodle Soup Consumption in Melamine Bowls and Total Melamine Excretion in Urine,” researchers measured the amount of melamine flowing through the study subjects’ bodies compared to eating the same soup out of ceramic bowls. “Melamine tableware may release large amounts of melamine when used to serve high-temperature foods” Their findings? “Melamine tableware may release large amounts of melamine when used to serve high-temperature foods”—and not even hot foods. “Melamine migration can be detectable from daily-use melamine-made tableware, even in the low temperatures,” like just warm water. Why do we care? Because the level of melamine you’re exposed to “is signiﬁcantly associated with kidney function deterioration in patients with early-stage CKD,” chronic kidney disease, in which even relatively “low melamine levels may cause a rapid decline in kidney function.” So, I would suggest glass, ceramic, porcelain, or stainless steel tableware instead. What about polyamide utensils, common black plastic spoons, spatulas, and the like? All sorts of different plastic materials are used in kitchen utensils. Polyamide is “typically used for turners [spatulas] or ladles due to their high heat and oil resistance.” “However, components of this plastic can migrate from the utensils into the food and consequently be ingested by consumers.” Out of 33 utensils tested, nearly 1 in 3 exceeded the upper safety limit. The German Federal Institute for Risk Assessment “recommends that consumers keep contact with food as brief as possible when using PA [polyamide] kitchen gadgets, especially at high temperatures,” such as above the temperature at which we may drink hot tea or coffee. A different survey of black plastic kitchen utensils found about a third contaminated with flame retardant chemicals. “Utensils for frying may lead to considerable dietary exposure.” Why? Because it may be made from plastic recycled from electronic equipment that was impregnated with the stuff. Then, should you dip the polyamide utensil into oil, the chemicals can trickle out, suggesting that using such “utensils for frying may lead to considerable dietary exposure.” The black dye itself in some polyamide utensils can leach out, too. Eventually, with enough use, the levels drop, but it may take the equivalent of boiling the utensils for about a hundred hours before the dye leaking approaches safety levels. It’s probably just easier to use utensils that are wooden or stainless steel. This is the last in a three-part series of cookware videos. If you missed the others, check out Are Aluminum Pots, Bottles, and Foil Safe? and Stainless Steel or Cast Iron: Which Cookware Is Best? Is Teflon Safe?. It may not be safe to microwave melamine, but what about microwaving in general? See Are Microwaves Safe? and The Effects of Radiation Leaking from Microwave Ovens. Key Takeaways Melamine, known for its use in hard plastic food contact items like cups and utensils, has been illegally added to protein products, leading to pet food recalls and disease and death of pets themselves, and later, to contaminated baby formulas and powdered milk in China. Melamine exposure, particularly from dishware, can lead to kidney problems, with significant implications for individuals with chronic kidney disease. Opt for safer alternatives like glass, ceramic, porcelain, or stainless steel tableware to minimize exposure to melamine. Polyamide utensils, like black plastic spoons and spatulas, pose migration risks, with some exceeding safety limits and potentially containing flame retardant chemicals. Choose wooden or stainless steel utensils over polyamide to reduce the risk of chemical exposure and dye leaching. To read the original article click here.

Nanoplastics Promote Conditions for Parkinson’s Across Various Lab Models

The AHA! Team — Mon, 26 Aug 2024 03:47:42 +0000

Duke Health – DURHAM, N.C. – A novel study sounds the alarm on the need for a new area of research. Nanoplastics interact with a particular protein that is naturally found in the brain, creating changes linked to Parkinson’s disease and some types of dementia. In a Duke-led study appearing Nov. 17 in Science Advances, the researchers report that the findings create a foundation for a new area of investigation, fueled by the timely impact of environmental factors on human biology. Improperly disposed plastics have been shown to break into very small pieces “Parkinson’s disease has been called the fastest growing neurological disorder in the world,” said principal investigator, Andrew West, Ph.D., professor in the Department of Pharmacology and Cancer Biology at Duke University School of Medicine. “Numerous lines of data suggest environmental factors might play a prominent role in Parkinson’s disease, but such factors have for the most part not been identified.” Improperly disposed plastics have been shown to break into very small pieces and accumulate in water and food supplies, and were found in the blood of most adults in a recent study. “Our study suggests that the emergence of micro and nanoplastics in the environment might represent a new toxin challenge with respect to Parkinson’s disease risk and progression,” West said. “This is especially concerning given the predicted increase in concentrations of these contaminants in our water and food supplies.” West and colleagues in Duke’s Nicholas School of the Environment and the Department of Chemistry at Trinity College of Arts and Sciences found that nanoparticles of the plastic polystyrene — typically found in single use items such as disposable drinking cups and cutlery — attract the accumulation of the protein known as alpha-synuclein. West said the study’s most surprising findings are the tight bonds formed between the plastic and the protein within the area of the neuron where these accumulations are congregating, the lysosome. Researchers said the plastic-protein accumulations happened across three different models performed in the study – in test tubes, cultured neurons, and mouse models of Parkinson’s disease. West said questions remain about how such interactions might be happening within humans and whether the type of plastic might play a role. And were found in the blood of most adults in a recent study “While microplastic and nanoplastic contaminants are being closely evaluated for their potential impact in cancer and autoimmune diseases, the striking nature of the interactions we could observe in our models suggest a need for evaluating increasing nanoplastic contaminants on Parkinson’s disease and dementia risk and progression,” West said. “The technology needed to monitor nanoplastics is still at the earliest possible stages and not ready yet to answer all the questions we have,” he said. “But hopefully efforts in this area will increase rapidly, as we see what these particles can do in our models. If we know what to look out for, we can take the necessary steps to protect ourselves, without compromising all the benefits we reap every day from plastics.” The study was funded by in part by The Michael J. Fox Foundation for Parkinson’s Research and the Aligning Science Across Parkinson’s initiative (ASAP-020527). In addition to West, study authors include Zhiyong Liu, Arpine Sokratian, Addison M. Duda, Enquan Xu, Christina Stanhope, Amber Fu, Samuel Strader, Huizhong Li, Yuan Yuan, Benjamin G. Bobay, Joana Sipe, Ketty Bai, Iben Lundgaard, Na Liu, Belinda Hernandez, Catherine Bowes Rickman, and Sara E. Miller. To read the original article click here.

Chemical Commonly Found in Consumer Products May Disrupt a Hormone Needed for Healthy Pregnancy

AHA Publisher — Fri, 14 Jan 2022 08:00:55 +0000

Rutgers University-New Brunswick via Newswise – Exposure to phthalates—a group of chemicals found in everything from plastics to personal care products to electronics—may disrupt an important hormone needed to sustain a healthy pregnancy, according to a Rutgers study. The study, which appears in Environment International, was among the first to examine the impact that phthalates, added to plastics to increase flexibility, have on the placental corticotropin releasing hormone (pCRH) that is produced by the placenta and increases throughout the course of pregnancy. The hormone plays an important role in promoting the onset of labor, but when levels are high or rise rapidly earlier in pregnancy, it may contribute to preterm birth and fetal growth problems as well as high blood pressure, diabetes, and postpartum depression. “We are all exposed to phthalates in our environment through the products we use and the foods we eat,” says Emily S. Barrett, an associate professor at the Rutgers School of Public Health and member of the Environmental and Occupational Health Sciences Institute. “Our findings show that these chemicals may alter the production of essential placental hormones, which has important implications for the course of pregnancy as well as subsequent child health and development.” The researchers analyzed data from 1,018 low-risk pregnant women carrying single fetuses at two time points, mid- and late pregnancy. They found that the presence of various phthalates was associated with higher pCRH hormone levels in mid-pregnancy, but lower pCRH later in pregnancy. These levels were strongest in women who developed pregnancy complications like gestational diabetes and high blood pressure, suggesting that women who develop complications may be particularly vulnerable to this hormonal disruption. This is among the first and largest study so far to examine how these chemicals and the connection with pCRH disrupt the function of the endocrine system, which is especially delicate during pregnancy. “Associations between phthalates and pCRH among women with pregnancy complications grew stronger across the course of pregnancy. We know very little about how women with pregnancy complications are affected by environmental exposures. This study sets the stage for future research in that area,” Barrett said. pCRH produced by the placenta is identical in structure to corticotropin-releasing hormone (CRH) produced by the brain when responding to stress. While this study did not find that women who had experienced childhood traumas were any more vulnerable to the hormone-disrupting effects of phthalates, earlier research found that pCRH levels were higher in women who have experienced childhood trauma suggesting that traumatic events may impact pregnancy decades later.
