Published on Leave a comment on A Mediterranean Style Diet Feeds Beneficial Gut Bacteria

The incidence of both intestinal bowel diseases (IBD) and colorectal cancer is rapidly increasing in developed countries (e.g., US, Canada, Europe). There are many theories over why this is occurring, with most researchers thinking a person's diet plays a role. A big suspect in promoting IBD and colorectal cancer is the Western diet, which has lots of ultra-processed foods and is also low in fiber.

A recent large study looked at 6 major diets and how they impact the gut microbiome. The six dietary patterns were: Western diet, Mediterranean diet, high-fiber diet, plant-based diet, high protein diet, and ketogenic diet.

And surprise, surprise - eating a Western diet resulted in having an increase in gut bacterial species linked to chronic inflammation, heart disease, colorectal cancer, IBD, and diabetes. The Mediterranean style diet had an increase in bacterial species linked to a lower risk of cardiovascular disease, IBD, and type 2 diabetes. In fact, all 6 diets had distinct bacterial profiles in the gut.

Bottom line: The foods a person eats can either feed and nourish beneficial bacteria or harmful bacteria (linked to cancer and IBD). Best for health is a Mediterranean style diet (lots of fruits, vegetables, whole grains, legumes, seeds, nuts), and avoiding ultra-processed foods. You are what you eat!

Hummingbirds like the red Cardinal flower (also called lobelia). Really like them. Butterflies also swarm to these flowers. Usually.

But not always. Since an immediate neighbor started using a mosquito service that uses high-volume pesticide applications of a synthetic pyrethroid (think of a leaf blower on steroids), there has been an absence of butterflies, bees, and hummingbirds in my garden. Other people also report this happening.

Even though the synthetic pyrethroids (e.g., Fendona) are not neonicotinoids, which we know kills bees - pyrethroids are also toxic to bees. Pyrethroids are broad-spectrum insecticides - that is, they kill a wide variety of insects indiscriminately. This totally destroys the biodiversity of species in the environment. We need bees, butterflies, hummingbirds, and other species!

But what are the pesticides doing to humans? Developing children? The developing fetus? Sick people? Everyone? Yes, there is accumulating evidence of health harms to humans, especially children and babies.

Uh-oh. The Earth is really warming up, and very rapidly. Sunday was the hottest day recorded globally. But then... Monday was even hotter! This means that in the space of several days, two global records were set in two days.

And it will continue to get warmer (hotter) in the coming months and years. We do know what is causing this climate change of increased global warmth - it's the burning of fossil fuels (e.g., gas, oil, coal). The big question - can humans change their ways?

From The New York Times, the Climate Newsletter: Earth’s Hottest Days Ever

Twice this week, global temperatures broke records, but scientists are more concerned about a longer-term pattern of hotter weather.

This past Sunday was the warmest single day ever recorded, according to the Copernicus Climate Change Service, the European Union-funded research organization. That is, until Monday, when global temperatures inched up a bit more. Then Monday became the hottest day in modern history, with an average global temperature of 17.16 Celsius or 62.88 Fahrenheit. Tuesday was almost as hot. ...continue reading "The Two Hottest Days On Earth Were This Week"

Published on Leave a comment on Aspirin and Lower Risk of Colorectal Cancer

Studies on aspirin keep coming. For decades, studies found that persons taking aspirin frequently have a lowered risk of developing colorectal (colon) cancer, and that they are less likely to die if they do develop colorectal cancer. A recent study confirmed these aspirin findings and looked at what is occurring.

Aspirin appears to boost or activate the immune system, which helps explain its protective effect in colorectal cancer. Clinical trials are going on now to test whether and how aspirin can be part of colorectal cancer treatment.

From Medscape: How Aspirin May Lower Risk for Colorectal Cancer

A 2020 meta-analysis, for instance, found that 325 mg of daily aspirin — the typical dose in a single tablet — conferred a 35% reduced risk of developing CRC, and a highly cited The Lancet study from 2010 found that a low dose of daily aspirin reduced the incidence of colon cancer by 24% and colon cancer deaths by 35% over 20 years.

The evidence surrounding aspirin and CRC is so intriguing that more than 70,000 people are currently participating in more than 2 dozen clinical studies worldwide, putting aspirin through its paces as an intervention in CRC.

But what, exactly, is aspirin doing?

Published on Leave a comment on Bees and Butterflies Now Missing From Yards

This year a number of persons reported to me that when their neighbors started with mosquito and tick control pesticide applications, they no longer have bees or butterflies in their yards. Even if they have lots of bee and butterfly friendly flowers, or lots of clover - they now rarely or never see bees and butterflies. This has also been my experience.

As I reported last year, this is because mosquito/tick services use pesticides that are highly toxic to bees and butterflies. The applicators hold pesticide sprayers at waist height that spray insecticides out at high volume, and usually walk along a property 's perimeter spraying. Looks like leaf blowers blowing out pesticides!

Typically pyrethroid and cypermethrin insecticides (e.g. made by Fendona) are used. These are broad-spectrum (kill many species, including bees), microencapsulated, long-lasting (up to 90 days) pesticides, and applications are usually every 3 weeks. So it's actually an over-application of the pesticides.

I observed an applicator walking along a neighbor's yard perimeter applying the insecticides at waist height directly into my hedges (yes, it is obvious to the applicator that they are on my property). As he walked along, I could see the hedges violently shaking from the high volume application.

By the way, that is a deliberate non-target application of pesticides, which is against the law in my state. But it's what these companies do with impunity - go look at their web-site photos. By the way, pesticide contamination of adjacent properties will always be a problem in suburban yards with this kind of application.

Bees are pollinators, and unfortunately they are in serious decline in the United States. Pesticides are a big cause. Pesticides, including pyrethroids, also have numerous health effects on humans - none of them good. Especially worrisome is exposure during pregnancy or in young children.

Interestingly, others and I have also noticed that bird species that were common in our yards no longer visit once a neighbor starts with the mosquito and tick pesticide applications. Hummingbirds, gold finches, black-capped chickadees, juncos, robins, song sparrows and other birds - all are now missing from yards.

Published on Leave a comment on Better Lung Function In Children Living Near Green Spaces

A recent large study found that exposure in childhood to more "green spaces" or a "greener neighborhood" results in better lung function in those children. Well, duh.. of course. The study needed to be done to show the health benefits of parks and other outdoor green spaces for children, and thus the need for green spaces in urban areas.

The study involved more than 35,000 children from eight European countries. They found that the more "green space" or "greener neighborhoods" exposure (meaning the more green spaces by the child's residence) that the children had in early childhood, the better it was for their lung function. On the other hand, the further away a child lived from green spaces, the lower the lung volume.

Why? The researchers point out that green spaces (parks, yards) reduce air pollution, which in turn affects respiratory health of children. It also exposes the children to beneficial microbes, which are good for their microbiome and immune system. Finally, playing outside (physical activity) is good for lung development and function.

From Science Daily: Children living in greener neighborhoods show better lung function

A large study of 35,000 children from eight countries has found a "robust" link between exposure to green spaces in early childhood and better lung function. The study, led by the Barcelona Institute for Global Health (ISGlobal), has been published in Environment International. ...continue reading "Better Lung Function In Children Living Near Green Spaces"

Published on Leave a comment on The Appendix Has Health Benefits

Over  time researchers have learned that the appendix is more complex than originally thought, and that it is beneficial to health. It's where good bacteria go to hideout during sickness (e.g., food poisoning) or when a person is taking antibiotics, and it acts as a "training camp" for the immune system.

This is the direct opposite of what was thought for years - that it is a vestigial organ with no purpose. Instead, research found that removing the appendix increases the risk for irritable bowel syndrome and colon cancer. It also plays a role in several medical conditions, such as ulcerative colitis, colorectal cancer, Parkinson's disease, and lupus.

One possibility is that it protects against diarrhea. The appendix acts as a safe house for beneficial bacteria. We now know that it contains a thick layer of beneficial bacteria. People who've had their appendix removed have a less diverse gut microbiome, and with lesser amounts of beneficial species.

By the way, recent research found that antibiotics can successfully treat up to 70% of uncomplicated appendicitis cases. For this reason, it is recommended that antibiotics should be tried first in uncomplicated appendicitis cases. And if needed (e.g., if there are recurrences of appendicitis) surgery can be done.

Excerpts from Medscape: The 'Useless' Appendix Is More Fascinating Than We Thought

When doctors and patients consider the appendix, it's often with urgency. In cases of appendicitis, the clock could be ticking down to a life-threatening burst. Thus, despite recent research suggesting antibiotics could be an alternative therapy, appendectomy remains standard for uncomplicated appendicitis.

But what if removing the appendix could raise the risk for gastrointestinal (GI) diseases like irritable bowel syndrome and colorectal cancer? ...continue reading "The Appendix Has Health Benefits"

Published on Leave a comment on Walking Helps Prevent Low Back Pain Episodes

Great news for individuals with lower back pain. Which is a lot of us. A recent study found that the simple act of walking helps  with prevention of low back pain episodes!

In the study, persons who had recently recovered from an episode of lower back pain were randomly assigned either to 1) an individualized and progressive walking intervention, along with 6 sessions with a physical therapist over a 6 month period (to discuss the walking) or to 2) a no treatment control group. Afterwards, the walking group took an a median of 208 days until their next activity-limiting episode of lower back pain, while the control (no walking) group took a median of 112 days.

In other words, walking regularly resulted in going twice as long until the next occurrence of low back pain compared to non-walkers. They also had fewer occurrences of activity limiting low back pain episodes. Note that these were individuals (43 to 66 years) who had a history of low back pain episodes

How much did they walk? The walkers kept a walking diary, with the median 80 minutes of walking in week 1, which increased to 130 minutes by week 12. They walked a median of 3 times in week one, which increased to 4 times in week 12.

From Science Daily: Walking brings huge benefits for low back pain

Adults with a history of low back pain went nearly twice as long without a recurrence of their back pain if they walked regularly, a world-first study has found. ...continue reading "Walking Helps Prevent Low Back Pain Episodes"

Published on Leave a comment on Raw Milk In Europe May Contain A Serious Virus

The CDC currently recommends only consuming pasteurized or ultra-pasteurized milk and dairy products. This is because heating milk kills off the bird flu virus (H5N1) now circulating among dairy cows in the USA. Another serious virus that pasteurization and ultra-pasteurization of milk kills off is the tick-borne encephalitis that occurs throughout central and eastern Europe.

Tick bites are the major way tick-borne encephalitis is spread. But a minority of cases are spread by consuming raw milk or dairy products from recently infected livestock (goats, sheep, and cows).

Tick-borne encephalitis is a serious viral infection of the central nervous system. It starts out with symptoms such as fever, headaches, chills, but up to 39% of cases result in more serious neurological symptoms (meningitis, encephalitis). Infected persons may experience long-term neurological effects lasting years.

Two ways to avoid the tick-borne encephalitis virus: only consuming pasteurized milk and dairy products (and avoiding raw milk and dairy products) or getting vaccinated with the tick-borne encephalitis vaccine (TicoVac, TBE vaccine).

Bottom line: Only consume pasteurized or ultra-pasteurized milk and dairy products.

From article (page 3) in Medscape: Fast Five Quiz: Diagnose and Treat Tick-Borne Illnesses

Tick-borne encephalitis virus can be transmitted by ticks and the alimentary tract. A recent meta-analysis of 410 foodborne tick-borne encephalitis cases, mostly from a region in central and eastern Europe, aimed to describe cases of tick-borne encephalitis acquired through alimentary transmission in Europe from 1980 to 2021. ...continue reading "Raw Milk In Europe May Contain A Serious Virus"

Published on Leave a comment on Carbon Dioxide Levels In Atmosphere Keep Rapidly Rising

It shouldn't be a surprise to read that carbon dioxide levels in the atmosphere are surging and accumulating faster than ever. In May, it surged to 427 parts per million (426.90 ppm) - while in 1960 it was about 320 ppm.  It's depressing, and it doesn't bode well for our future.

These high levels of carbon dioxide are a major driver of the record-setting heat we've been experiencing in recent years. Carbon dioxide is the gas that accounts for the majority of global warming (yes, climate change) and is caused by human activities. The human activities are burning of fossil fuels, such as gas and oil - in vehicles, coal-fired plants, large industrial operations, ships, airplanes, rockets.
