Xenoestrogens: Unveiling the Hidden Threat to Hormonal Balance


The world is increasingly attacked by a complex web of environmental pollutants. One particular class of compounds, xenoestrogens, stands out for its potential to disrupt our endocrine system. 

Xenoestrogens are simply synthetic or naturally occurring chemicals mimicking estrogen in the body. Whether you’re a guy, girl, or other, this has the potential to interfere with proper hormonal balance. 

Understanding Xenoestrogens: What Are They?

Xenoestrogens are a subset of a broader group of chemicals known as endocrine-disrupting chemicals or EDCs. As stated above, these can mimic the effects of estrogen on the body. This is bad even for women, because your body is a finely tuned machine, requiring a certain balance of estrogen to other hormones. 

What’s more, these compounds are not produced naturally in the body. Instead, they originate from external sources, usually industrial byproducts such as pesticides, plastics, and even some personal care products. When introduced into the body, xenoestrogens interact with estrogen receptors and affect various physiological processes.

Sources of Xenoestrogens

  • Plastics: Bisphenol A (BPA) and phthalates, are found in many plastic products, such as water bottles, but also common receipts you get at stores, and plastic food containers are common sources of xenoestrogens. These chemicals then leach into food and beverages from containers, leading to unintended exposure.
  • Pesticides: Common pesticides, such as atrazine, have estrogenic properties. These can contaminate soil and water supplies, potentially entering the food chain even if you only buy organic produce.
  • Pharmaceuticals: Certain medications, including birth control pills and hormone replacement therapy, contain synthetic hormones that can act as xenoestrogens if they find their way into the environment. One very true example that sounds crazy is that most common tap water is xenoestrogenic.
  • Personal Care Products: Many common cosmetics, skincare products, and toiletries contain parabens and phthalates, which can be absorbed through the skin.
  • Processed Foods: Food additives such as propyl gallate and butylated hydroxyanisole (BHA), can contain xenoestrogens.
  • Industrial Chemicals: Polychlorinated biphenyls (PCBs) and dioxins are xenoestrogenic industrial byproducts contaminating air, water, and soil. 

Health Implications of Xenoestrogens

Ok, so there are xenoestrogens in just about everything. So what?

  • Hormonal Disruption: Xenoestrogens disrupt a very delicate balance of your endocrine system. They bind to estrogen receptors, which can lead to hormonal imbalances. This, in turn, can impact fertility, reproductive health, and sexual development.
  • Cancer Risk: Xenoestrogens may contribute to the development of several hormone-related cancers, including breast, ovarian, and prostate cancer. 
  • Reproductive Effects: Xenoestrogens impact fertility and reproductive health in both men and women. In women, they can interfere with the menstrual cycle and reduce fertility, while in men, they may lead to reduced sperm quality and quantity.
  • Thyroid Dysfunction: Xenoestrogens interfere with normal thyroid gland functioning, which can lead to thyroid disorders and related health issues.
  • Early Puberty: Early exposure to xenoestrogens can accelerate the onset of puberty, which can cause a host of physical and psychological issues in children.
  • Neurological Effects: Recent research suggests xenoestrogens have neurological effects, possibly contributing to neurological conditions like autism and attention-deficit/hyperactivity disorder (ADHD).

Ways to Reduce Xenoestrogen Exposure

Xenoestrogens are everywhere. But the situation is not hopeless. There are a number of ways you can reduce your exposure to Xenoestrogens. While you might not be able to cut them out completely, here are some ways to reduce your exposure – which is better than just full-throttle consumption. 

  • Choose Natural and Organic Products: Opt for personal care products and cosmetics 100 percent free from parabens, phthalates, and other endocrine disruptors. Look for certifications like “organic” and “natural.”
  • BPA-Free Plastics: Use BPA-free containers and avoid microwaving plastic containers, as heat can promote the release of BPA. Better yet, opt for metal or glass. 
  • Eat Organic: Organic fruits and vegetables can reduce pesticide exposure. Wash all non-organic produce thoroughly to minimize any pesticide residues that might be present. 
  • Filtered Water: Invest in a high-quality water filter to remove some potential contaminants, including xenoestrogens, from your tap water.
  • Reduce Processed Foods: Minimize consumption of processed and packaged foods, which often have xenoestrogenic properties.

Xenoestrogens are a pervasive but often overlooked threat to hormonal balance and overall health. They can disrupt your endocrine system and lead to serious health issues, including hormonal imbalances or even cancer. 

By being mindful of potential sources of xenoestrogens and taking reasonable steps to reduce exposure, individuals can mitigate the impact of xenoestrogens on health and well-being.

Weight Loss Drugs Reduce Risk of Kidney Disease

Recent research reveals that weekly injections of semaglutide medications, such as Ozempic, significantly lower the risk of severe kidney outcomes, major cardiovascular events, and death among individuals with type 2 diabetes and chronic kidney disease.

Diabetes is a major risk factor for kidney disease, a leading cause of death globally. Approximately one in three people with diabetes also suffers from chronic kidney disease. The new study demonstrates that weekly injections of semaglutide can reduce the risk of severe outcomes from diabetic kidney disease by about 24%. These outcomes include significant loss of kidney function, kidney failure, and death from kidney or cardiovascular causes.

The study, conducted on about 3,500 participants across 28 countries, compared those receiving weekly 1-milligram injections of semaglutide with those receiving a placebo. The participants were followed for an average of about three and a half years. Findings showed that severe outcomes occurred 331 times among those treated with semaglutide, compared to 410 events among those given the placebo. This translates to 5.8 events per 100 years of follow-up for semaglutide users, versus 7.5 events per 100 years for the placebo group.

The study also found broader benefits of semaglutide treatment. Kidney function declined more slowly, the risk of major cardiovascular events such as heart attack was 18% lower, and the risk of death from any cause was 20% lower among those treated with semaglutide compared to the placebo group. These benefits suggest that semaglutide not only helps manage blood sugar levels but also offers significant protection against other complications associated with diabetes and kidney disease.

Implications for Treatment

This study highlights the transformative potential of semaglutide for people with diabetes and kidney disease. The effectiveness of semaglutide was found to be particularly significant in those at the highest risk of severe outcomes, including kidney failure and cardiovascular events. Researchers noted that a combination of therapies might be crucial for comprehensive management, as many participants were also receiving other diabetes treatments.

While other drug treatments exist for diabetic kidney disease, semaglutide showed additional benefits beyond current standards of care. The study was published in the New England Journal of Medicine and presented at the European Renal Association Congress. The trial’s promising results led to its early conclusion based on the recommendation of an independent monitoring committee.

There are significant disparities in the prevalence of diabetes and kidney disease in the United States, particularly among Black, Hispanic, and American Indian adults. Despite these disparities, most participants in the semaglutide trial were White, limiting the assessment of its effectiveness across diverse populations. Ensuring that effective treatments like semaglutide reach all high-risk groups is essential for reducing health disparities and improving outcomes for all patients.

Semaglutide presents a highly effective therapy for reducing severe kidney and cardiovascular outcomes in people with type 2 diabetes and chronic kidney disease. It addresses a broad spectrum of risks associated with diabetes, including weight loss, blood pressure reduction, and direct effects on kidney health. Moving forward, the challenge lies in ensuring that these benefits reach all patients, particularly those at the highest risk who may have less access to advanced treatments. The transition from research to practical implementation is crucial to maximizing the positive impact of this therapy on public health.

Is Weekly Insulin the Way Forward for Diabetes Treatment?


Insulin therapy, crucial for many people with diabetes, typically involves daily injections to manage blood sugar levels. However, a new development could change this routine. Novo Nordisk, the maker of a once-weekly insulin injection called insulin icodec, is seeking approval from the US Food and Drug Administration (FDA). Despite potential benefits, the FDA’s Endocrinologic and Metabolic Drugs Advisory Committee is divided on whether the advantages outweigh the risks.

The advisory committee recently evaluated the safety and efficacy of insulin icodec, focusing on its use in people with type 1 diabetes. Members considered whether the benefits of this weekly insulin outweigh its risks for improving glycemic control. Out of the 11 members, four voted in favor, while seven opposed. The committee’s recommendations will be considered by the FDA, though the agency is not obligated to follow them when making its final decision.

Clinical Trial Findings on Weekly Insulin Treatment

Phase 3 clinical trials indicate that insulin icodec is more effective at reducing high blood glucose levels compared to the daily therapy insulin degludec. However, insulin icodec also has a higher incidence of hypoglycemia, a condition characterized by low blood glucose levels, which can lead to severe health issues such as loss of consciousness or seizures. The data showed that insulin icodec was associated with 50 to 80% more clinically significant or severe hypoglycemia compared to insulin degludec after 52 weeks.

Some panel members, like Dr. Barbara Onumah, believe that insulin icodec could be a valuable addition to diabetes management, even though it may not be suitable for everyone. She emphasized the need for clear guidelines on mitigating and treating the risk of hypoglycemia if the product is approved.

Conversely, other members, such as Dr. Matthew Drake, expressed concerns over the safety profile of insulin icodec compared to insulin degludec, which he considers the current gold standard. Erica Brittain, a biostatistician, acknowledged the theoretical benefits of fewer injections but noted that the trial data did not show a significant improvement in glycemic control, which complicates the decision.

Potential Benefits of Weekly Insulin

A weekly insulin injection could simplify treatment regimens, making it easier for patients to adhere to their prescribed schedules. Currently, about 53% of adults with type 1 diabetes stick to their insulin therapy schedules, with approximately 22% missing at least one basal insulin dose over any 14-day period. Nonadherence to insulin therapy can lead to serious complications such as diabetic ketoacidosis.

Novo Nordisk is not alone in developing a weekly insulin therapy. Eli Lilly recently announced that its once-weekly insulin, efsitora alfa, was found to be equally safe and effective in Phase 3 trials involving adults with type 2 diabetes. However, Eli Lilly has not yet sought FDA approval for this product.

The potential approval of insulin icodec as the first weekly insulin injection in the United States represents a significant advancement in diabetes care. While the convenience of fewer injections is appealing, the higher risk of hypoglycemia is a critical concern. As the FDA deliberates, the insights from the advisory committee and further evaluations will be crucial in determining whether this new treatment will become available to patients.

A New Weapon in the Fight Against Dementia: Olive Oil


Good news for Italian food fans: A new study suggests that olive oil can reduce your risk of dementia-related mortality. The study, published in JAMA Network Open, utilized data from two large U.S. prospective cohorts: the Nurses’ Health Study and the Health Professionals Follow-Up Study. Researchers found that individuals consuming more than 7 grams of olive oil daily had significantly lower dementia-related mortality rates compared to those with lower intake.

The study included 92,383 participants, with a participant pool comprising 65% women and an average age of 56 years. The follow-up period spanned 28 years, during which there were 37,649 total deaths, including 4,751 dementia-related deaths. At the beginning of the study, the average olive oil consumption was 1.3 grams per day.

Participants consuming more than 7 grams of olive oil daily, approximately half a tablespoon, demonstrated a range of positive lifestyle attributes. These included higher caloric intake without a higher BMI, better diet quality, higher alcohol consumption, increased physical activity, and a lower likelihood of smoking. Overall, the study found that consuming at least 7 grams of olive oil daily was associated with a 28% lower risk of dementia-related death.

Olive Oil’s Role in Reducing Dementia Risk


The researchers explored the substitution of olive oil for other fats in the diet. Replacing 5 grams per day of margarine or mayonnaise with olive oil was linked to an 8% to 14% lower risk of dementia-related deaths. However, substituting other vegetable oils or butter did not significantly reduce the risk. The study concluded that higher olive oil intake was associated with a lower risk of dementia-related mortality, irrespective of diet quality.

Broader Implications for Health

Beyond its implications for dementia, the study’s findings support current dietary recommendations to choose olive oil and other vegetable oils for cognitive health. Olive oil’s rich content of vitamin E and polyphenols, which are antioxidants that protect cells and blood vessels in the brain, as well as its anti-inflammatory properties, contribute to its health benefits. Inflammation, often an underlying cause of dementia and cognitive decline, can be mitigated by these properties.

For those looking to increase their olive oil intake, it can be easily incorporated into daily meals. Substituting other cooking oils with olive oil, making salad dressings, or using it as a marinade for proteins are practical ways to boost consumption. Both butter and olive oil can have unique health benefits, but it’s generally recommended to opt for unsaturated fats like olive oil most of the time and use butter occasionally.

Other Health Benefits of Olive Oil

Olive oil offers a range of health benefits beyond reducing dementia risk. Previous studies using similar cohort data have shown that higher olive oil intake is associated with a lower risk of cardiovascular disease, cancer, neurodegenerative diseases, and respiratory disease mortality. Additionally, a 2022 meta-analysis linked higher olive oil consumption to a lower risk of diabetes, cardiovascular disease, and all-cause mortality.

While olive oil supplements are available, experts suggest that consuming olive oil in food form is more beneficial. Supplements may not provide the same health benefits if added to an unhealthy diet. Incorporating olive oil into a balanced diet is preferable for achieving the maximum benefits.

The study reinforces the health benefits of olive oil, particularly in reducing the risk of dementia-related mortality. By making olive oil a regular part of a healthy diet, individuals can potentially enhance their cognitive health and overall well-being. As research continues to uncover the wide-ranging benefits of olive oil, it remains a valuable addition to daily nutrition for people of all ages.
