Well, the forbidden words list in the USA is growing this year. That is, forbidden words in the US government. Censored words. Some of the many words: climate change (yes, it exists), clean energy (e.g., wind), global warming (temperatures are increasing, with new records being set continuously), water pollution, air pollution, solar energy, gender (we are all a gender), transgender, abortion. And on and on. Denying something's existence doesn't make it not exist.

The words are not allowed on government sites, in grant proposals, grant applications, or in research. Different government departments have different banned words lists (e.g., 110 words or phrases in the US Dept. of Agriculture research service - such as clean water, microplastics) Who knew that in 2025 that censorship would be so large scale? Yes, this is an attack on knowledge, on research, on medicine, and science. On all of us.

3 articles about the large-scale censorship. From NPR: Energy Dept. tells employees not to use words including 'climate change' and 'green'

The Department of Energy has told employees to avoid using certain words, including "climate change," "green" and "sustainable," according to an internal email sent to staff and obtained by NPR. ...continue reading "List of Banned Words In the United States Is Growing"

Published on Leave a comment on Weed-Killer Glyphosate and Cancer

Remember when back in 2015 the IARC (International Agency for Research on Cancer) said that the pesticide glyphosate (the active ingredient in Roundup) is a probable human carcinogen (cancer causing)? And the American chemical industry and FDA pooh-poohed that? Well, there have been a number of studies since then finding that yes, glyphosate results in tumors and other health harms, and is cancer causing (carcinogenic).

Glyphosate is a commonly used herbicide (weed killer), the most used herbicide in the world. Its use has been increasing annually, especially due to the increase in genetically modified crops being grown.

In the latest study, an international team of researchers found that long-term daily exposure (starting prenatally and continuing after birth) to low glyphosate levels considered "safe" by government agencies resulted in multiple benign and malignant tumors, and increased rates of early death in the rats after birth. Yes, the study was done with rats, but... they are mammals, just like us humans. Rats are frequently used in studies to assess chemical safety.

The doses used in the study are currently considered safe by regulatory agencies and correspond to the EU Acceptable Daily Intake (ADI) and the EU’s No Observed Adverse Effect Level (NOAEL) for glyphosate. By the way, European standards are STRICTER than USA standards. A person eating a typical diet with non-organic foods easily ingests the levels considered acceptable by European governing bodies, and in the US ingests even more. [NOTE: Eat organic foods to avoid glyphosate.]

From Environmental Health News: Common pesticide causes multiple malignant tumors in rats

In short: Exposure to glyphosate herbicides caused multiple benign and malignant tumors in rats, including leukemia and cancers of the skin, liver, thyroid, nervous system, ovary, uterus, and kidneys, among others. ...continue reading "Weed-Killer Glyphosate and Cancer"

Published on Leave a comment on Loss of Smell from A COVID Infection Can Linger For At Least Two Years

Millions of us have had a least one COVID infection. Many suffered a loss of smell during the infection. A recent study by NYU Langone researchers found that the loss of smell can linger for at least 2 years after the infection. And even if you thought that your smell was never impacted or that it has recovered, it actually may not have fully recovered, but only partially recovered.

Among the 3525 participants in the study that reported a loss of smell during a COVID infection - 80% still  had not fully recovered their sense of smell 2 years later, and for 23% it was severely diminished or lost. Interestingly, 66% of persons who originally had a COVID infection, but did not notice any smelling issues, also scored abnormally low on the evaluation done 2 years after the infection.

It can be said that their sense of smell has dulled (olfactory dysfunction). This reduced ability to smell is called hyposmia. Researchers administer a 40-odor test to persons to determine their smelling ability. To help recover the sense of smell, vitamin A supplementation and olfactory training are being tried.

From Science Daily: Millions could be living with hidden smell loss after COVID without knowing

People who suspect that their sense of smell has been dulled after a bout of COVID-19 are likely correct, a new study using an objective, 40-odor test shows. Even those who do not notice any olfactory issues may be impaired. ...continue reading "Loss of Smell from A COVID Infection Can Linger For At Least Two Years"

Published on Leave a comment on Commonly Used Chemical and Parkinson’s Disease

Over and over studies have found links with certain toxic chemicals (some pesticides and the chemical trichloroethylene) and Parkinson's disease. Another recent study found that long-term exposure to high levels of the chemical trichloroethylene (TCE) in the outside air increases the risk of developing Parkinson's disease.

TCE is an industrial solvent used in numerous industrial (as a degreaser), consumer, military, and medical applications. For example, it is used in dry cleaning clothes, removing paint, as a degreaser, carpet cleaner, and engine cleaner. Unfortunately, since it is environmentally persistent, it lingers in the air, water (e.g., in the military base Camp Lejeune), and soil across the US.

Bottom line: Outdoor air pollution also matters, not just the chemicals you are directly exposed to (e.g., in your job). TCE is a hazardous air pollutant, so avoid living (if you can) near a TCE emitting facility (especially in Lebanon, Oregon and Corydon, IN) because the risk of developing Parkinson's disease is the highest for people living near there.

From Science Daily: The invisible chemical in the air that could be raising Parkinson’s risk

Long-term exposure to the industrial solvent trichloroethylene (TCE) outdoors may be linked to an increased risk of Parkinson's disease, according to a large nationwide study published in the October 1, 2025, issue of Neurology, the medical journal of the American Academy of Neurology. ...continue reading "Commonly Used Chemical and Parkinson’s Disease"

Published on Leave a comment on Preventing Diabetes With A Mediterranean Diet and Increased Physical Activity

There has been lots of research in the past decade over the benefits of eating a diet rich in fruits, vegetables, whole grains, nuts, and legumes, especially a Mediterranean style diet. Health benefits include lowering chronic inflammation and a lower incidence of a number of chronic diseases, including type 2 diabetes.

A recent study conducted in Spain added a twist to this. The researchers found that eating a lower calorie Mediterranean diet and increased levels of physical activity, resulted in a 31% reduction in the development of type 2 diabetes, as well as a greater weight loss and reduction of their waist size. The comparison group were persons who ate a Mediterranean diet, but without lowering their calorie intake or increasing physical activity over the 6 years of the study.

The subjects in this study were 4756 overweight or obese adults with metabolic syndrome, but without prior cardiovascular disease or diabetes - thus a group that was at high risk for developing type 2 diabetes. The calorie reduction goal was to eat about 600 fewer calories per day.

Excerpts from Science Daily: Scientists found a smarter Mediterranean diet that cuts diabetes risk by 31%

Eating a Mediterranean-style diet with fewer calories, adding moderate physical activity, and receiving professional guidance for weight management can lower the risk of developing type 2 diabetes by 31%. That is the key finding of PREDIMED-Plus, a large clinical trial led in Spain by the University of Navarra together with more than 200 researchers from 22 universities, hospitals, and research institutes. The project was carried out in over 100 primary care centers within Spain's National Health System. ...continue reading "Preventing Diabetes With A Mediterranean Diet and Increased Physical Activity"

Published on Leave a comment on Record High Levels of Carbon Dioxide In Our Atmosphere

The US government would like to shut the Mauna Loa observatory in Hawaii down because it measures levels of atmospheric CO2, a measure of climate change. Well, unlike the US government, the rest of the world is very, very concerned about increasing CO2 levels in our atmosphere, and what increasing levels of greenhouse gases are doing to our climate and environment.

The United Nation's World Meteorological Organization (WMO) does not hesitate to loudly announce that CO2 levels are steadily rising, with record high levels in 2024, and what this means for our world going forward. Their words: it's "turbocharging our climate and leading to more extreme weather".

The important thing to know is that CO2 levels keep increasing, and each year new record high levels are set. Highest ever levels were in 2024. A big reason CO2 levels are increasing is due to the burning of fossil fuels (oil, gas, coal). The increase in wildfires is also contributing.

Excerpts from New Scientist: CO2 levels in Earth's atmosphere jumped by a record amount in 2024

Atmospheric carbon dioxide levels jumped by a record amount in 2024 to push concentrations to their highest point since measurements began, the UN’s World Meteorological Organization (WMO) has reported.

Between 2023 and 2024, the global average concentration of CO2 surged by 3.5 parts per million (ppm) to reach 423.9 ppm, the WMO has said. This is the largest increase since modern measurements started in 1957 and is well in excess of the 2022 to 2023 increase of 2.3 ppm. ...continue reading "Record High Levels of Carbon Dioxide In Our Atmosphere"

Published on Leave a comment on Carbon Dioxide Levels Still Going Up Even When Not Monitored

If there is no data about something, then there is no problem because there is no data that says whether there is a problem or not. Duh... It's the new official US government policy (ignorance is bliss!), whether there is a government shut-down or not.

Unfortunately, in 2025 the US has stopped data collection and actually eliminated many  departments and sites that have been collecting information - whether diseases, losses due to major disasters (which are increasing due to climate change), toxics and pollutants in our air and water, and even how much carbon dioxide is in the air.

The US government announced in 2025 that it would close the Mauna Loa observatory (the Global Monitoring Laboratory) that measures carbon dioxide in the air. Carbon dioxide levels have been steadily increasing since measurements started, due to the burning of fossil fuels (climate change!). Well, with the government shutdown, this is what one sees when going to the site: Nothing much. Many of the old measurements are no longer there, as well as nothing new being graphed.

Luckily, at this point not all data has been removed. As you click through the site, can still see that in August 2025 the carbon dioxide levels were 425.48 ppm and that 10 years ago the weekly level was 398.62 ppm. It's going up year by year.

Many studies are finding the existence of microplastics everywhere in the environment and in our bodies. Microplastics occur when plastic items degrade over time. A recent study confirmed that drinking from plastic water bottles is a major source of the microplastics and nanoparticles that we ingest.

Microplastics are 1 µm to 5 mm in size and nanoplastics are even smaller (less than 1 µm).  They are usually invisible to the naked eye.

Study researchers did a review of over 141 studies and concluded that the average person ingests 39,000 to 52,000 microplastics each year, and those who drink bottled water ingest about 90,000 more particles than persons only drinking tap water.

Research on long-term health impacts (if any) of ingesting and breathing in microplastics and nanoparticles is just starting, but what has been done is concerning - at a minimum they are causing inflammation in our bodies. Other research suggests numerous health effects (e.g., respiratory issues, reproductive problems, disruption of the immune system).

Bottom line: buy, drink, and store as beverages in glass bottles, and drink tap water. Avoid single-use plastic water bottles.

From Phy.org: Chronic risks from single-use plastic water bottles are dangerously understudied, says study

The sun-drenched paradise of Thailand's Phi Phi islands isn't the usual starting point for a Ph.D. But for Sarah Sajedi, those soft, sandy beaches—or rather, what she found under them—inspired her pivot from a business career to an academic one. ...continue reading "Bottled Water A Major Source of Microplastics and Nanoparticles"

Stress can have harmful health effects on the body, including the gut microbiome. A recent article in the medical site Medscape reviewed studies of chronic stress and the gut microbiome and found that chronic stress alters the gut microbiome, resulting in gut dysbiosis (the gut microbial community is imbalanced or out-of-whack).

For example, researchers have found alterations in gut microbes, less diversity of microbes, and fewer numbers of certain beneficial microbes  in those with PTSD (post-traumatic stress disorder).

Interestingly, the researchers stress that a good diet (e.g., Mediterranean diet, including fermented foods) will help the gut microbiome, but that there isn't any evidence for probiotic supplements. In other words, don't take store-bought daily supplements, but instead focus on eating well, exercise, and getting enough sleep.

From Medscape: How Chronic Stress Disrupts the Gut Microbiome

Chronic psychological stress is common. A 2023 survey revealed that about one quarter of US adults reported high stress levels, and three quarters reported that chronic stress affects their daily lives.

Emerging evidence suggests that chronic stress not only exacts a high toll on mental health but also can wreak havoc on all levels of gastrointestinal (GI) functioning, all the way down to the microbiome. ...continue reading "Chronic Stress and the Gut Microbiome"

Many people suffer from intestinal ailments, such as intestinal bowel diseases and intestinal bowel syndrome. Over and over researchers find that altered gut microbiomes and intestinal lining alterations (e.g., "leaky gut") may be involved. A recent study from MIT found that the amino acid cysteine  promotes healing of the small intestinal lining.

Once again, a person's diet may be the answer. Cysteine is found in many high-protein foods. Foods that are rich in cysteine include: poultry, eggs, beef, fish (e.g., salmon, halibut, tuna), whole grains, soybeans, and some nuts (almonds).

While the study was conducted in mice, the researchers felt the results also applied to humans.

From Medical Xpress: A cysteine-rich diet may promote regeneration of the intestinal lining

 A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune signaling pathway that helps stem cells to regrow new intestinal tissue.

This enhanced regeneration may help to heal injuries from radiation, which often occur in patients undergoing radiation therapy for cancer. The research was conducted in mice, but if future research shows similar results in humans, then delivering elevated quantities of cysteine, through diet or supplements, could offer a new strategy to help damaged tissue heal faster, the researchers say. ...continue reading "Healing the Small Intestine and the Amino Acid Cysteine"
