By now no one should be surprised that the male urethra has a microbiome - the community of microbes (bacteria, viruses, fungi) that live there. After all, we have millions of microbes living all over and in us.

There is the core microbiome generally found in all adult male urethras and then also microbes that vary from person to person. The urethra is the tube through which both urine and semen leave the male body.

A recent study found that having sex with a woman (vaginal sex) influences what lives in the male urethral microbiome. The researchers found that some of the men had microbes in the male urethra that are normally found in the female reproductive tract, specifically women with vaginal dysbiosis (yeast infections). This means the women transmitted the microbes to the men during sex. These microbes are not part of the male core urethral microbiome.

Interestingly, even if the men have microbes associated with bacterial vaginosis in the microbiome of the urethra, the men (unlike the women) didn't have any symptoms of an infection.

The CDC reports that autism (autism spectrum disorder) rates are still increasing in the US, from 1 in 150 twenty years ago to 1 in 36 children in 2020. That's huge!

It's not just better screening and diagnosis. Rates are increasing so rapidly that researchers agree that there are environmental factors going on. But what are they?

The researchers of the report point out known factors (e.g., age of parents, multiple gestation birth, prematurity, genetics), but what is not discussed are all the chemical toxins in our environment that people are exposed to both prenatally and after birth (postnatally). Studies find that pregnant women are exposed to more harmful industrial chemicals nowadays than ever before.

For example, lead, heavy metals, and pesticides. People use pesticides in the home, on home exteriors, in their gardens and lawns, on pets, on crops, they're in foods we eat, in water we drink, even in rainfall (!). Millions of pounds are used each year in the US. Many of them have neurological effects.

This means that babies and young children are also exposed to more pesticides than ever before. The American Academy of Pediatrics has been warning about the dangers of pesticide exposure in children for years.

Excerpts from Futurity (site for research news from universities): United States autism rates hit new high

More children have been diagnosed with autism than at any time since monitoring began more than two decades ago, according to new federal studies. About 4% of 8-year-old boys and 1% of 8-year-old girls, in the United States have autism, according to the US Centers for Disease Control and Prevention (CDC). ...continue reading "Autism Spectrum Disorder Rates Hit New High"

A number of studies in the past decade found that exposure to furry pets (e.g., cats, dogs) in  the first year of a child's life is important for preventing later allergies (animal, food, pollen). A recent large study from Japan found that exposure to pet cats and dogs during pregnancy (developing fetus) and the first year of life confirms that furry pet exposure is important in reducing the risk of food allergies until at least 3 years of age.

While pet dogs kept inside had a protective effect, pet dogs kept outside did not. Also, the type of pet was important. Indoor pet dog exposure reduced the number of children with egg, milk, and nut allergies, while cat exposure was associated with fewer egg, wheat, and soybean allergies. However, these beneficial results did not apply to pet hamsters, birds, and turtles.

Why is this happening? It's thought that early in life exposure to furry pets (dander, microbes) helps train the developing immune system. Their gut microbes also have differences. By the way, other studies found that exposing a child in the first year of life to potential problem foods (e.g., peanut butter, eggs) reduces the incidence of that specific food allergy.

From Science Daily: Living with pet cats or dogs is associated with fewer food allergies in young children, study finds

In an analysis of over 65,000 infants from Japan, children exposed to pet cats or indoor dogs during fetal development or early infancy tended to have fewer food allergies compared to other children, according to a study published March 29, 2023 in the open-access journal PLOS ONE by Hisao Okabe from the Fukushima Regional Center for the Japan Environment and Children's Study, Japan, and colleagues. ...continue reading "Reduce the Risk of Food Allergies By Having Pet Dogs or Cats"

Once again Europe is better at protecting people than the US (Surprise, surprise! Not...) This time a study compared pesticide use on golf courses in different regions of the US and 3 European countries (UK, Denmark, Norway).  It found that the number of pesticide products and pesticide use is significantly higher in the US than in Europe - the risk to people from pesticides is 15 times higher in the US than the European countries.

This is because Europe is actively trying to reduce the amount of pesticides used, while the US is not. The European Union has banned a number of the most dangerous pesticides, while the US has not. Fewer pesticides (20 or fewer) are allowed to be used on golf courses in the 3 European countries, while many more (200 to 250) are allowed in the US.

Important: Pesticides drift onto neighboring properties when applied, they contaminate water and soil, people breathe them in, get them on their skin (and so absorb them). They have harmful effects to our health and environment, even at low doses.

Excerpts from Beyond Pesticides: Pesticide Dangers at Golf Courses Much Higher in the U.S. than Europe, Study Finds  

Pesticide use on golf courses in the United States poses significantly more risk to human health than those in Europe, according to a study published this month in Science of the Total Environment. The findings highlight yet another area of land management where the U.S. is dangerously behind the European Union, as these countries are set to ban pesticides in parks, playgrounds, and playing fields, and have established a 50% reduction goal for agriculture by 2030.

Meanwhile U.S. agencies continue to perpetuate widespread toxic pesticide use, with U.S. Department of Agriculture Secretary Tom Vilsack even working to counter the EU’s reduction goals through a separate, “market-oriented” initiative alongside pesticide industry-friendly countries like UAE and Brazil. ...continue reading "European Governments Protect Residents By Allowing Fewer Pesticides On Golf Courses Than in the US"

For years there has been much concern over chemicals that act as endocrine disruptors (hormone disruptors) in the personal products that we use on a daily basis.  One big concern is whether these chemicals, such as parabens and phthalates, are causing breast cancer (as well as other harmful health effects). Because whatever you use on your skin, will get into you.

A recent study looking at these harmful chemicals found that women switching to paraben and phthalate free cosmetic products had a quick effect (within 28 days) on lowering their levels in the body (blood, urine, breast tissue cells). Which then resulted in lowering breast cancer markers to a "normal" expression. Wowza!

What you can do: Check the ingredients in the lotions you use. Are there parabens and phthalates in it? Spend your money on safe lotions and other personal products. Go to EWG (ewg.org) or mamavation.com for lists of safe products. Also: Ways to lower your exposure to harmful chemicals

For example, the commonly used lotion Lubriderm to this day has several types of parabens (e.g., methylparaben) in it. No, no, no... Why are they still in the lotion? Note that our government is not protecting us from these harmful chemicals. (Instead Big Business and big money is more important.)

Another important nutrient for brain health is magnesium. A recent study found that ingesting higher levels of magnesium from foods (dietary magnesium) is associated with better brain health and brain volume. Brains normally shrink a little with age, but ingesting higher levels of dietary magnesium resulted in less age-related shrinkage.

The researchers found that the effects were especially beneficial for postmenopausal women. It is important to note that all study participants had recommended or higher levels of magnesium intake from foods. No one had a magnesium deficiency. Recommended dietary allowances are 400–420 mg for men and 310–320 mg for women - but the results from this study suggest that ingesting even more from foods is better.

In other words, consider magnesium important for a healthy brain. Try to increase intake of magnesium rich foods. The researchers point out that recent studies suggest that dietary magnesium is associated with better cognitive function and may reduce the risk of dementia.

Foods rich on magnesium: pumpkin seeds, almonds, spinach, cashews, pumpkin seeds, chia seeds, peanuts, shredded wheat cereal, quinoa, soymilk, black beans, edamame, dark chocolate, bread, whole wheat, avocado, potato, nuts, bananas.

Want to improve your odds of not getting a chronic disease, such as heart disease or diabetes? A recent study found that following any healthy dietary pattern, whether Mediterranean or DASH or Diabetes Risk Reduction Diet or other similar healthy dietary styles, are all linked to a lower risk of chronic diseases.

These healthy dietary patterns all stress fruits, vegetables, whole grains, seeds, nuts legumes, but they vary in minor ways, e.g., whether salt, coffee, tea, or wine is allowed. People weren't following specific diets over the 3 decades of the study, but it's how they generally ate - their dietary pattern.

The Harvard T.H. Chan School of Public Health researchers found that persons who were in the top 10% of a healthy dietary pattern, no matter which one, were compared to persons in the bottom 10% of that dietary pattern. Overall they found that being near the top of any of the healthy dietary patterns was associated with a lower disease risk.

Interestingly, larger amounts of coffee, whole grains, wine and desserts had lower risk of associated major chronic diseases.

Eating some foods frequently were associated with developing major chronic diseases, such as processed meats, energy drinks, french fries, red meat, and eggs.

Another large study found that eating a Mediterranean diet is beneficial to health - specifically, that it is associated with a decreased risk for dementia. As much as 23% lower (compared to those who didn't eat a Mediterranean style diet)! It didn't matter if a person had a genetic risk for dementia or not - diet was more important.

By the way, other studies also find that eating a Mediterranean style diet has benefits for the brain and body.

A Mediterranean style diet is one rich in fruits, vegetables, whole grains, legumes (beans, lentils), nuts, seeds, herbs, spices, and olive oil. Some lean meat, especially chicken, and fish. This way of eating is high in fiber (good for health!). Try to avoid processed meats, highly processed foods, fast food, and hydrogenated oils. Eat less meat in general.

Experts at Newcastle University found that individuals who ate a Mediterranean-like diet had up to 23% lower risk for dementia than those who did not. ...continue reading "A Mediterranean Style Diet Is Associated With A Lower Dementia Risk"

Dry cleaning Credit: Wikipedia

A widely used cleaning chemical (even in dry cleaning!) has been linked to Parkinson's disease by an international team of researchers. In a piece published in the Journal of Parkinson's Disease, they built a strong case that the chemical trichloroethylene (TCE) is one of the causes of Parkinson's disease. This is based on the existing evidence (both human and animal).

Trichloroethylene was widely used in the past (600 million lbs. per year at its peak in the 1970s), and is still widely used. It is environmentally persistent, and contaminates soil, air, and water. Vapors from underground water and soil contamination seep out into homes, schools, and workplaces. It is known to be carcinogenic (cancer causing) and associated with numerous cancers and other health harms, including birth defects.

TCE has had numerous industrial, consumer, military, and medical applications. For example, it is used in dry cleaning clothes, removing paint, as a degreaser, carpet cleaner, and engine cleaner. It even was used to produce  decaffeinated coffee in the past! Many US sites are now contaminated with TCE, including military bases.

The scientists point out that Parkinson's disease has increased so much (by 500%) that there must be exposure to something else (or more than 1 thing), and they find a strong link to TCE. They refer to Parkinson's as "the world's fastest growing brain disease".

By the way, a number of other toxic chemicals are associated with Parkinson's disease, (e.g., some pesticides, some drugs), long-term welding exposure, and even head trauma.

The researchers urge banning both the production of TCE and its use, urge the clean up sites that are contaminated with TCE, and more research.

Excerpts from Medical Xpress: Common dry cleaning chemical linked to Parkinson's

A common and widely used chemical may be fueling the rise of the world's fastest growing brain condition—Parkinson's disease. For the past 100 years, trichloroethylene (TCE) has been used to decaffeinate coffee, degrease metal, and dry clean clothes. It contaminates the Marine Corps base Camp Lejeune, 15 toxic Superfund sites in Silicon Valley, and up to one-third of groundwater in the U.S. TCE causes cancer, is linked to miscarriages and congenital heart disease, and is associated with a 500% increased risk of Parkinson's disease. ...continue reading "Common Cleaning Chemical Linked to Parkinson’s Disease"

Eating your fruits and vegetables, especially a rainbow assortment of them, is associated with a lower risk of prostate cancer as well speeding up recovery in men who received radiation treatment for prostate cancer.

Two recent studies by the same group of Australian researchers found that certain micronutrients found in foods are lower in men with prostate cancer (compared to healthy men). These are lycopene, selenium, lutein, lycopene, α-carotene, β-carotene. Lycopene and selenium appear to be especially important.

Tomatoes and tomato products (e.g., tomato sauce) are an especially good source of lycopene. Other lycopene rich foods are: watermelons, grapefruits, guava, melons, papayas.  Selenium rich foods include Brazil nuts, seafood, organ meats, beef, pork, chicken, turkey, and eggs.
