Published on Leave a comment on Study Finds Young Children Are Exposed To A Wide Variety of Pesticides

Most children in the US are exposed to a wide variety of pesticides, both prenatally and after birth. Pesticides and their residues are in foods, water, rain, fog, interiors of many homes,  gardens, lawns, workplaces, farms - basically everywhere. A recent study of children found that an average of 31 pesticides were found in the urine of each child (infants and toddlers).

In the study 438 urine samples collected from 187 children were analyzed for the presence of pesticide residues. A total of 215 pesticides were identified in the urine samples, with 51 pesticides detected in at least 20% of the samples. Sixteen pesticides were identified as highly detected ones - they were found in over 60% of the samples. On average, there were 31 pesticides per child  - with children ranging from 21 to 50 compounds per sample.

At this time, it is unknown what constant low level exposure to mixtures of pesticides does to a person long-term, but studies done so far are finding harmful health effects. Children are especially vulnerable to pesticides. Unfortunately, when the EPA looks at pesticide exposure, it only looks at one pesticide at a time - not at mixtures.

Health effects: Some pesticides are more hazardous than others, including effects such as endocrine disrupting effects, neurological damage, reproductive effects, and increased risk of cancer. Many scientists suspect that chronic low-level pesticide exposure may even be contributing to the year by year drop in sperm numbers and fertility problems.

Bottom line: Try to lower pesticide exposure by eating organic foods, not using pesticides routinely in yards and in homes (instead use organic products or least toxic IPM), and avoiding antimicrobial, antibacterial, and anti-odor products. [More tips.]

A recent study published in Environment and Health found that young children are exposed to a wide range of pesticides during key periods of growth and development. ...continue reading "Study Finds Young Children Are Exposed To A Wide Variety of Pesticides"

Published on Leave a comment on All Daily Physical Activity Reduces Cancer Risk

Study after study finds all sorts of health benefits from exercise and physical activity. Even if it's only in short bursts. A recent large study found that all physical activity is better than just sitting in reducing cancer risks by about 7% for at least 13 cancers that have been associated with inactivity.

Standing up reduces cancer risks from just sitting for hours. And moving in any way (light activity) reduced the cancer risks even more than just standing. But vigorous activity reduced cancer risks even more. As little as three minutes of daily vigorous activity (e.g., hurrying up flights of stairs) was equivalent to 90 minutes of light-intensity movement in reducing cancer risks.

Bottom line: Move, move, move - whenever you can. Even if it's only for a few minutes. And even if it's a gentle stroll. The average American sits about 9 1/2 hours a day - and research shows that is not good for health.

From the Washington Post: 3 minutes of this activity may cut the risk of 13 cancers, study finds

To reduce your risks for at least 13 types of cancer, jog up and down the nearest steps for three minutes or stand up from your desk or couch for 30.

Either strategy might help drop your risks of certain cancers by as much as 7 percent, according to a new study of how the ways we move — and don’t move — during the day affect our chances of malignancies.

Published on Leave a comment on Another Disappointing Vitamin D3 and Cancer Result

Another disappointing result for vitamin D3, this time looking at metastatic colorectal cancer progression and survival. For years, there was hope that taking high doses of vitamin D3 would help in preventing all sorts of cancers or would help in the treatment of cancer.  But the studies keep finding no effects from vitamin D3 supplements.

Researchers found that adding high dose vitamin D3 to standard chemotherapy plus bevacizumab did not improve progression-free survival (PFS) in patients with previously untreated metastatic colorectal cancer, when compared to those who received the same treatment except that they received a daily standard dose vitamin D3 supplement.

High dose vitamin D3 was 8000 IU daily for 14 days, followed by 4000 IU daily. Standard dose vitamin D3 (the  control group) was 400 IU daily.

Excerpts from Medscape: Does High-Dose Vitamin D3 Supplementation Improve CRC Survival?

High-dose vitamin D3 supplementation added to standard chemotherapy plus bevacizumab does not improve progression-free survival (PFS) compared with standard-dose vitamin D3 in patients with previously untreated metastatic colorectal cancer (mCRC). Among 455 randomized patients, median PFS was 11.8 months in the high-dose group vs 10.3 months in the standard-dose group, with no significant differences in objective response rates or overall survival. ...continue reading "Another Disappointing Vitamin D3 and Cancer Result"

Published on Leave a comment on After Embassy Air Pollution Monitors Were Dismantled, Air Pollution Increased

It shouldn't be a surprise, but after the US stopped air pollution monitoring at its embassy sites around the world in early 2025 - air pollution in those areas jumped.

Researchers reported a 24 to 33% jump in air pollution within months, according to satellite measurements.

The program measuring air quality was started in 2008, when  the US government installed air pollution monitors at more than 80 embassies and consulates worldwide. Air quality results were made public. Research found that this led to a significant improvement in air quality at those sites. This was especially important for poor and middle-income countries that had limited resources for air quality monitoring.

Many studies find many health benefits (especially for the heart, lungs, and brain) when people breathe cleaner air, and increased early death rates when air quality is poor.

If there is no information about the air pollution in an area, then there is no problem. After all, it costs industries money to have pollution controls. Pollute away! As we all know, ignorance is bliss.

From NPR - Air pollution spiked after the Trump administration stopped embassy monitoring

Growing up in Shanghai in the early 1990s, Eric Zou remembers the air. "I lived a couple of miles next to a chemical plant and it was just really bad, really foggy," he says. "It's the middle of the day, but you can't see the sun."

Intensive industrial activity blanketed many cities in China during the 1990s and 2000s with extremely hazardous air. But Zou, now an environmental economist at the University of Michigan, says that many people didn't really understand this smog as air pollution, or something that could harm them.

"When you have a big smog event, people often talk about that as fog, they think it was just like bad weather," says Zou. One big key to changing that sentiment, he says, was information initially provided by the United States. ...continue reading "After Embassy Air Pollution Monitors Were Dismantled, Air Pollution Increased"

Imagine that instead of drilling and filling cavities at the dentist, a gel could be applied to the damaged tooth and it would rebuild new tooth enamel. A new product is in development to do just that!

Scientists at the School of Pharmacy, Univ. of Nottingham are developing a gel that is applied to a tooth with weakened or damaged tooth enamel, and which draws calcium from saliva to grow a new mineral layer. It's not exactly tooth enamel, but it does closely match healthy tooth enamel and so far appears to withstand the stressors that healthy teeth are exposed to (e.g., chewing, acidic foods, tooth brushing).

Stay tuned for developments!

A newly developed dental gel may be able to rebuild damaged tooth enamel, potentially creating a new approach to preventing decay and restoring worn teeth. ...continue reading "A Gel Is Being Developed to Regrow Tooth Enamel"

Published on Leave a comment on Combining Diet and Exercise Can Result in Type 2 Diabetes Remission

Over the years a number of studies have shown that intense dieting with weight loss can reverse type 2 diabetes. Another recent study came up with similar results. This time a study found that slightly more than half of persons following a low-calorie diet and an exercise program (aerobic and resistance exercise) reversed their type 2 diabetes within 12 weeks.

All the participants were between 8 to 45 years, and had an early onset type 2 diabetes diagnosis within the past 6 years. Such early onset type 2 diabetes typically means a high lifetime risk of complications. The participants were randomly assigned to either a control group that received general standard care, or the exercise and diet group.

The diet-exercise group followed a low-calorie diet (800 to 900 calories per day) for 12 weeks. During that time they also had a supervised hour of exercise (both aerobic, resistance) 2 times per week and once per week independent exercise. Between 13 to 24 weeks they followed a weight-maintenance diet and exercised independently.

Total weight loss was about 18.5 pounds in the diet-exercise group, but only 2.6 pounds in the control group. At the end of 24 weeks 54% of the diet-exercise were in type 2 diabetes remission, but only 4% of the control group.

The researchers demonstrated that having the participants follow the exercise program meant that they maintained muscle mass during the weight loss period. This showed that mass and muscle preservation is achievable with rapid weight loss -  a problem that typically occurs during rapid weight loss.

Bottom line: Following a low calorie diet and exercising, with resultant weight loss, can reverse type 2 diabetes. Not always, but for most it can.

From Medical Xpress: Low-calorie diet and exercise put early-onset type 2 diabetes in remission for 54% of participants

New research presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) and appearing in The Lancet Regional Health Americas journal shows that in people who have developed early-onset type 2 diabetes (EOT2D) (aged under 45 years), around half these T2D cases can be reversed with a low-energy diet combined with a structured exercise program. ...continue reading "Combining Diet and Exercise Can Result in Type 2 Diabetes Remission"

The US is now in the middle of a measles outbreak, with Pennsylvania currently experiencing the most cases. The Pennsylvania Department of Health said that as of October 16, there have  been 1260 documented cases of measles and 5 deaths from measles in Pennsylvania this year, with a 6th death being investigated.

They also report that fewer than 1% of the cases had been vaccinated, and 33% were under 18 years old. Almost all of the cases occurred since April 2026. They additionally report that 9589 doses of the measles vaccine (MMR) have been given this year. Two doses aof the vaccine are needed for protection.

Bottom line: Get vaccinated! Especially scary complications of measles, which can be long-term, are death (about 1 to 3 out of every 1000 measles cases in children), and encephalitis (swelling of the brain) in about 1 out of every 1000 measles cases in children.

Published on Leave a comment on Almost 500 Chemicals In Pesticide Products Linked to Breast Cancer

Women are concerned about breast cancer, especially with the cancer rates increasing each year. Many wonder if chemicals in the environment are contributing to breast cancer incidence, and whether there are ways to prevent breast cancer.

A recent study looked at 920 chemicals that can increase breast cancer risk, and  found that exposure to breast cancer promoting chemicals is everywhere. The researchers found that 485 chemicals used in pesticide products, including common consumer goods (e.g., insect repellents, sanitizing products), are linked to breast cancer. Additionally, about 462 of the chemicals have been detected in food, 162 in drinking water, 142 in pharmaceuticals, and 106 in building (construction) materials.

The breast cancer chemical list includes both active ingredients found in pesticides and inert ingredients (which typically are not listed on labels, but can be just as harmful). It includes pesticides used in conventional (non-organic) farming, in outdoor lawn and garden pesticides, pesticides meant for indoor use, lice treatments for children and adults, and flea and tick treatments on pets.

Keep in mind that pesticides applied to crops leave residues, which means they eventually wind up in the foods we eat. And yes, this is why most Americans have detectable pesticides in their bodies (typically blood and urine is tested as part of biomonitoring).

In case you're wondering, the US EPA is not doing a good a job of regulating pesticides and protecting residents of the US - due to persons from the chemical industry or with ties to the pesticide industry (e.g., industry lobbyists) in EPA leadership. And also because laws protecting us have been significantly weakened in the last few years.

Some pesticides banned throughout much of the world (due to their health and environmental risks) are heavily used in the U.S. Noted examples: Atrazine (over 76 million pounds used annually in the US) and paraquat (over 10 million pounds used annually in US).

Bottom line: Try to buy and eat untreated or organic foods. Use unscented or fragrance-free products whenever possible (whether personal care products or cleaning products). Try to avoid using products that say they are "antimicrobial" or "antibacterial". Use least-toxic Integrated Pest Management (IPM) or organic pest control (whether for insects or weeds) both indoors and outdoors.

From The Guardian: New research finds 485 chemicals in US pesticide products linked to breast cancer

New research has identified at least 485 chemicals used in US pesticide products that are linked to breast cancer, raising questions about the safety of food and other products at a time when early onset breast cancer rates are surging worldwide. ...continue reading "Almost 500 Chemicals In Pesticide Products Linked to Breast Cancer"

Published on Leave a comment on September Was Hottest On Record For the United States

Does it seem like summer is going on longer and longer? And that crisp fall days are a thing of the past?  Well, you are correct. Summer temperatures are lasting longer.

September was the second hottest September globally since record-keeping started in 1850. Global ocean surface temperatures were the warmest on record for September. And for the 48 contiguous United States: it was the hottest in 132 years of record-keeping (when averaged throughout the 48 states).

Do you see the pattern here? Month after month new records are being set. With temperatures trending higher and higher.

Excerpts from Yale Climate Connections: September 2026: 2nd-hottest September for Earth, hottest for the U.S.

September 2026 was the planet’s second-hottest September since modern record-keeping began in 1850, NOAA’s National Centers for Environmental Information, or NCEI, reported October 9. NASA and the European Copernicus Climate Change Service also rated it as the second-hottest September, behind 2023. The global average temperature for January-September 2026 was the second-highest on record, trailing only 2024. ...continue reading "September Was Hottest On Record For the United States"

Published on Leave a comment on Drinking Orange Juice Daily Has Health Benefits

Many of us drink a daily glass of orange juice thinking it is healthy for us and because it contains vitamin C. But is that true?

While some in the medical field view orange juice as basically orange-flavored sugar in a glass, others find orange juice to be a healthy beverage - one that is linked to a lower incidence of cardiovascular diseases.

A recent study found that there are numerous health benefits from drinking  orange juice daily. Regular consumption can influence the activity of thousands of genes in our immune cells - genes that help control blood pressure, improve inflammation, metabolism, and blood sugar control. Studies have also found improvements in cholesterol and blood vessel health - thus influencing long-term heart health.

How much orange juice to drink for health benefits? One cup of pure pasteurized orange juice daily should be sufficient. Note that in the study, adults drank 500 ml (2 cups) of pure pasteurized orange juice for 2 months. After 60 days, many genes associated with inflammation and higher blood pressure became less active.

From Science Daily: Drinking orange juice every day may change thousands of genes

Most of us think of orange juice as a simple breakfast habit, something you pour without much thought. Yet scientists are discovering that this everyday drink may be doing far more in the body than quenching thirst. ...continue reading "Drinking Orange Juice Daily Has Health Benefits"
