There is concern in the United States about the increasing rates of colon cancer in young persons. Currently it is the leading cause of cancer in persons under 50 years. Some possible causes being examined are ultra-processed foods (over 50% of calories eaten daily by Americans), low fiber intake, and microplastics.

This is why the results of a recent study are especially concerning: about 71% of baby and toddler foods sold in the United States are ultra-processed. Snack sized packages and pouches were especially likely to having ultra-processed ingredients, as well as high levels of sugar and sodium (salt).

How to recognize ultra-processed foods? Read ingredient labels and if there is something that normally is not found in a person's kitchen, then it is ultra-processed. [Good book about this topic: Ultra-Processed People]

Examples of ingredients found in ultra-processed foods: emulsifiers, carrageenan, mono- and diglycerides, soy lecithin, polysorbate, cellulose, colors, titanium dioxide, high fructose corn syrup, hydrogenated oils, dextrose, whey protein, nitrates, artificial flavors, natural flavors, colors, etc. Natural flavors are laboratory concoctions, even if they are "organic".

Global Warming Is Now Accelerating

SimaMarch 26, 2026March 27, 2026Leave a comment

The past few years have been the hottest globally since records have been kept, and have broken temperature records. And the pace of global warming is accelerating! The rate has surged so much that it is nearly double what it was in the 1970s. Yikes!

This means climate change is speeding up. Temperatures, storms, droughts, wildfires, and so on. Carbon dioxide levels are at the highest level in about 2 million years. All of this has been predicted by climate change models. So no - it is not just normal swings in climate. In fact, scientists feel we're close to Earth's tipping points (e.g, Atlantic Ocean currents weakening and slowing down.)

It is past time for governments to address this issue. But will they?

From YaleEnvironment360: Global Warming Is Accelerating, Study Shows

The Earth is warming at the fastest rate on record as emissions hit new highs and critical carbon sinks break down.

From Science Daily: Scientists detect a sudden acceleration in global warming

Global warming has been increasing at a faster pace since about 2015, according to a new study from the Potsdam Institute for Climate Impact Research (PIK). By adjusting global temperature records to remove known natural influences, researchers were able to identify a statistically significant rise in the rate of warming for the first time. ...continue reading "Global Warming Is Now Accelerating"

Eating Wild Blueberries Has Health Benefits

SimaMarch 20, 2026March 20, 2026Leave a comment

Some foods appear to have especially powerful health benefits. Berries are very beneficial, especially blueberries. (Or at least they have been studied more than other berries.) A recent study found that frequent or daily consumption of wild blueberries is especially beneficial for cardiometabolic health, including vascular health.

Blueberries contain lots of fiber, polyphenols (which have powerful effects on vascular health), antioxidants, flavonoids (anthocyanins), and micronutrients. Wild blueberries have more of all these compared to farmed blueberries. Blueberries are especially beneficial for vascular health because they reduce inflammation and vascular dysfunction.

Bottom line: Researchers suggest eating daily half a cup to one cup blueberries, especially wild blueberries, for health benefits, such as lowering inflammation. (Less is good also - better to eat some than none)

Medical Xpress: Studies suggest Maine wild blueberries support gut and heart health

Wild blueberries—the iconic Maine crop dotting hillsides, decorating sweatshirts and adding personality to local menus—is more than a cultural symbol. More than 20 years of preclinical and clinical studies suggest that regularly consuming wild blueberries supports gut and heart health and may reduce risk factors associated with chronic disease. ...continue reading "Eating Wild Blueberries Has Health Benefits"

Sometimes Getting A Tattoo Can Result in Eye Problems

SimaMarch 20, 2026March 20, 2026Leave a comment

Tattoos are incredibly popular throughout the world. One rare, but very concerning result from getting a tattoo is tattoo-associated uveitis. This is an inflammation of the eye, which can even cause permanent vision loss.

The most common health complications of tattoos are local inflammations, infections, allergic reactions at the site of the tattoo, and other inflammatory immune responses. Uveitis is a rare inflammatory response, which is consistently associated with long-term inflammation at the tattoo site (meaning that the inflammation has spread to the eye).

A recent review of studies found that tattoo-associated uveitis was associated with black ink and larger tattoos. Uveitis treatments included: 70.5% of individuals were treated with corticosteroids (with 50% needing long-term treatment), immunosuppressants (38.6%), and 16% had removal of the tattoo by excision. 16% also needed intraocular pressure management.

Different countries have different regulations regarding tattoo inks, with the European Union having stricter regulations than other countries. While the following article discusses tattoo-associated uveitis cases in Australia, it also occurs in the United States.

Bottom line: Monitor tattoos to see if there is long-term inflammation (swelling, redness).

Excerpts from The Conversation: What’s the link between tattoos and vision loss? 2 optometrists explain

Getting a tattoo can be a thrilling, albeit painful, experience.

About one-third of Australians have a tattoo, with many getting inked as a rite of passage. However, a small but increasing number of Australians are being diagnosed with a rare tattoo-related eye condition. It’s known as tattoo-associated uveitis and can cause permanent vision loss. ...continue reading "Sometimes Getting A Tattoo Can Result in Eye Problems"

Fixing Indoor Mold Problems Results In Fewer Asthma ER Visits

SimaMarch 18, 2026March 20, 2026Leave a comment

Mold exposure can be a trigger for respiratory ailments, including sinusitis and asthma. A recent study conducted in New York City's public housing found that fixing mold problems in apartments led to a big decrease in emergency visits for severe asthma attacks. Duh!...of course...

They found an average of nine fewer asthma-related emergency department visits per 1000 residents per year, or nearly 2800 fewer emergency department visits per year overall. Residents in nearby housing (apartments) not part of NY City's Housing Authority was the comparison group.

It makes sense that when the trigger for an asthma attack is removed, that there are fewer asthma attacks resulting in emergency room visits. But at least now the results have been quantified in a study. (NOTE: the study did not look at incidence of sinusitis, but one would expect the same type of results - if prolonged mold exposure triggers sinusitis, then cleaning it up prevents sinusitis).

From Medscape: Fix Mold, Reduce Asthma ED Visits?

An effort to remediate mold in public housing in New York City (NYC) was associated with thousands fewer emergency department visits for asthma per year, according to research presented at the American Academy of Allergy, Asthma & Immunology (AAAAI)2026 Annual Meeting. ...continue reading "Fixing Indoor Mold Problems Results In Fewer Asthma ER Visits"

Microplastics Found In Higher Levels In Prostate Cancer Tumors

SimaMarch 5, 2026March 6, 2026Leave a comment

Microplastics are turning up everywhere in our environment, including us. A recent small study found microplastics in 90% of human prostate cancer tumors, and at much higher levels than in nearby healthy tissue.

The tumor samples contained about 2.5 times more plastic than nearby healthy prostate tissue. This led the researchers to suggest that microplastic exposure may be a risk factor for prostate cancer. This is because chronic inflammation is considered a risk factor for the development of cancer.

Microplastics are tiny plastic particles (smaller than 5 millimeters) that occur as plastics get worn down, degrade, or get heated. They get into the air, water, soil, and throughout the environment. The particles are so small that after they are inhaled or ingested (in our food and water), they travel to the lungs, blood, and organs. The health effects of plastic particles in our bodies are still mainly unknown, but so far studies are finding oxidative stress and chronic inflammation.

From Science Daily: Microplastics found in 90% of prostate cancer tumors, study reveals

A new study has found tiny plastic particles in nine out of 10 men diagnosed with prostate cancer. Researchers also discovered that these microplastics were present at higher concentrations in cancerous tumors than in nearby noncancerous prostate tissue. ...continue reading "Microplastics Found In Higher Levels In Prostate Cancer Tumors"

Tires Are A Source Of Microplastics In Urban Air

There is much concern over the amounts of microplastics and nanoplastics in the environment, especially since they are turning up wherever we look. Including inside human bodies (e.g., the brain, blood, lungs, our bones), with mainly unknown health effects. A recent study found that an important source of microplastics and nanoplastics in urban air (in heavy traffic areas) comes from vehicle tires.

This occurs from tire abrasion - tires get worn down when vehicles are driven and also when braking occurs, and the tire abrasion particles get released into the air. In this study, they accounted for about 65% of the total plastic particles in the air in a heavy traffic area in Leipzig, Germany. Microplastics are smaller than 5 mm, and nanoparticles are even smaller (smaller than 1 micrometer).

According to the researchers, residents spending 24 hours a day in the high traffic area would inhale approximately 2.1 micrograms of plastic particulates per day, which is about 0.7 milligrams per year. So far it other studies find that this can result in oxidative stress and chronic inflammatory reactions in the lungs.

From Phys.org: Microplastics and nanoplastics in urban air originate mainly from tire abrasion, research reveals

Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: Around 4% of the particulate matter consists of plastic. Around two-thirds of this comes from tire abrasion. ...continue reading "Tires Are A Source Of Microplastics In Urban Air"

Once again, a recent study found that daily consumption of coffee has health benefits.

Recent research found that drinking a moderate amount of coffee (2 to 3 cups of daily) or 1 to 2 cups of tea daily was associated with a lower risk of dementia and better cognitive function. Decaf coffee appeared to have no effect on risk of dementia or cognitive functioning.

Persons with the highest intake (2 to 3 cups or more daily) of caffeinated coffee had an 18% lower risk of dementia compared with those who drank little or no caffeinated coffee. The large study followed people for as long as 43 years.

From Medical Xpress: Consuming 2–3 cups of coffee daily associated with lower dementia risk, better cognitive function

A new prospective cohort study by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard analyzed 131,821 participants from the Nurses' Health Study (NHS) and Health Professionals Follow-Up Study (HPFS), finding that moderate consumption of caffeinated coffee (two to three cups a day) or tea (one to two cups a day) reduced dementia risk, slowed cognitive decline, and preserved cognitive function. ...continue reading "Consuming Coffee Or Tea Daily Associated With Lower Risk of Dementia"

Elderberries Have Health Benefits

SimaFebruary 23, 2026February 23, 2026Leave a comment

People are always looking for foods that seem especially beneficial for health. Colorful vegetables and fruits fall into this category, especially berries, because of the polyphenols they contain. Recent research found that elderberries may help with insulin control, reduce fat production, and improve metabolic health - at least in this study using mice.

Interestingly, the researchers found that the microbes in the gut break down the polyphenols in foods. The researchers pointed out that other fruits and berries have similar effects to elderberries. But be careful - don't eat large amounts of raw elderberries by the fistful, because unripe elderberries also contain cyanide, which can cause nausea and vomiting.

Excerpts from Food and Wine: This Antioxidant-Rich Berry Could Be a Big Deal for Blood Sugar Control, Researchers Say

- Researchers at the Cleveland Clinic found that a compound in elderberries, cinnamic acid, may help improve insulin control and reduce fat production in mice with a healthy gut microbiome.
- The study shows that gut bacteria can transform elderberry compounds into metabolites that support improved metabolic health, potentially informing treatments for insulin resistance and fatty liver disease.
- While promising, scientists caution that more research is needed before recommending elderberry supplements — and remind readers that raw elderberries can be toxic if eaten unripe.

Physical Activity Slows Down Kidney Function Decline That Occurs With Aging

SimaFebruary 21, 2026February 23, 2026Leave a comment

Chronic kidney disease (CKD) is a growing problem globally, especially in aging populations. As people age, their kidney function declines - and this is a normal part of aging. A recent study found that physical activity slows this kidney function decline.

The study followed healthy individuals (aged 50 to 64 years at the start), who had varying physical activity levels, over an 11 year period. The researchers found that there is a dose response effect from physical activity - more active persons had a slower annual kidney function decline, as well as a much lower risk of accelerated kidney function decline.

The slowest level of kidney decline was in persons who were physically active almost every day (at least 5 days a week) and who engaged in more intense exercise. Note that physical activity is not just doing exercises - it's physical activity of all sorts. Yes, walking counts.

The researchers viewed physical activity as having reno-protective effects - in both the general population and in persons with CKD. This is because it lowers the risk of developing CKD, but it also slows kidney function decline. By the way, other studies have also found physical activity or exercise beneficial in slowing down the kidney function decline that occurs with aging.

From Medscape: Physical Activity May Slow Kidney Function Decline

Increased physical activity was associated with a substantially lower risk for kidney function decline, with the strongest effects seen with higher frequencies and intensities of activity, according to a new longitudinal study. ...continue reading "Physical Activity Slows Down Kidney Function Decline That Occurs With Aging"
