Published on Leave a comment on Eating A Diet Rich in Flavanols May Help With Memory

One fear people have is of developing problems with their memory in their later years, called age-related memory loss. A recent study finding a possible way to maintain memory in older adults is intriguing and offers hope. And best of all, it's fairly easy to do - just increase the intake of flavanol rich foods.

A large Columbia University study of adults over age 60 found that daily flavanol supplementation (cocoa extract with 500 mg flavanols) over a 3 year period improved the memory of persons whose diet was low in flavanol intake from foods, but not in persons with high intake of flavanols. The researchers suggest that a low flavanol diet is one of the drivers of age-related memory loss.

The researchers stated that flavanols only improved memory processes governed by the hippocampus, and did not improve memory mediated by other areas of the brain.

Flavanols are natural substances found in certain fruits and vegetables, especially berries, onions, kale, lettuce, tomatoes, apples, grapes, and cocoa. Flavanols are a type or class of flavonoids, all of which have health benefits. Eat a variety of plant foods (includes tea and wine) to ensure you're eating a variety of flavonoids.

Some other benefits of flavonoids: they are anti-inflammatory, anti-oxidative, have anti-mutagenic and anti-carcinogenic properties, lower heart disease death rates, and prevention of heart disease.

For years I've been concerned about spray foam insulation that is blown into attics and walls. Yes, it is promoted on popular home renovation shows. But what is not discussed is that the chemicals in the foam would be outgassing for years and the occupants of the home would be breathing it in.

Finally, I'm starting to see concerns raised by others - not just harmful health effects from the chemicals, including flame retardants, but also harms to the house itself. It turns out the industry is hiding the harms.... (why doesn't that surprise me?)

Excerpts from an article by Alden Wicker from VTDigger (an independent Vermont news website that publishes watchdog reports): 'I wanted to cry': Devastating risks of spray foam insulation hidden from Vermont homeowners

Londonderry contractor Abe Crossman was keeping busy with small projects at his family’s home in June 2020 during the newly arrived coronavirus pandemic. He was working outside when he noticed that the paint was peeling off the trim at the peak of the gable end of his roof. 

With 25 years of building experience, he knew that peeling paint indicated the presence of moisture. But the location was odd — that trim underneath the overhang should stay dry. So he grabbed a ladder and a pry bar to take a closer look. 

His stomach dropped as he sank the pry bar into the soft wood sheathing underneath the trim and peeled away the vinyl siding down to four feet below the roof line. What had been wood disintegrated into dust in front of his eyes, he later recalled, leaving behind nothing but spray polyurethane foam insulation. ...continue reading "Serious Problems With Spray Foam Insulation Used In Homes"

Published on Leave a comment on Record High Temperatures Predicted For Next Five Years

Are you ready for the world getting hotter over the next 5 years? And along the way setting record highs?

The World Meteorological Organization (WMO) predicts that the next 5 years are likely to have temperatures soaring to record highs. The causes are climate change (from heat-trapping greenhouse gasses) plus a naturally occurring El Nino (which is expected to start this summer).

Thus WMO Secretary-General Professor Petteri Taalas warns us:

“A warming El Niño is expected to develop in the coming months and this will combine with human-induced climate change to push global temperatures into uncharted territory,” he said. “This will have far-reaching repercussions for health, food security, water management and the environment. We need to be prepared.”

Why isn't everyone in the US government (including Senate and House of Representatives) taking serious steps about climate change? Our climate is changing!

From the World Meteorological Organization: Global temperatures set to reach new records in next five years

Global temperatures are likely to surge to record levels in the next five years, fuelled by heat-trapping greenhouse gases and a naturally occurring El Niño event, according to a new update issued by the World Meteorological Organization (WMO). ...continue reading "Record High Temperatures Predicted For Next Five Years"

Published on Leave a comment on We Leave DNA Everywhere We Go

Our DNA is everywhere. A recent study reports that everywhere we've been, we leave traces of DNA - even in the air, soil, and water. And this DNA (called environmental DNA or eDNA) is easy to sample.

This could be a privacy issue someday. Since it's so easy to collect a person's DNA in the air, soil, or water, does this mean we give consent to having someone or a company analyze and trace it to us? Will ethical guidelines be implemented about how this information can be used? Who will enforce them?

This issue is not an exaggeration. Researcher D.J. Duffy said: "We've been consistently surprised throughout this project at how much human DNA we find and the quality of that DNA," Duffy said. "In most cases the quality is almost equivalent to if you took a sample from a person."

From Science Daily: Human DNA is everywhere. That's a boon for science -- and an ethical quagmire

On the beach. In the ocean. Traveling along riverways. In muggy Florida and chilly Ireland. Even floating through the air.

We cough, spit, shed and flush our DNA into all of these places and countless more. Signs of human life can be found nearly everywhere, short of isolated islands and remote mountaintops, according to a new University of Florida study.  ...continue reading "We Leave DNA Everywhere We Go"

Published on 6 Comments on Ten Plus Years of Successfully Treating Sinus Infections With Probiotics

It is now my eleventh year of successfully treating sinus infections with only the probiotic Lactobacillus sakei. This includes regular sinus infections, chronic sinusitis, and even when there are just a few sinus symptoms (you know, the gradual slide toward sinusitis). No antibiotics and no antibacterials in all this time! Yes, it still feels miraculous!

Studies show that the beneficial bacteria Lactobacillus sakei occurs naturally (in tiny amounts) in healthy sinuses, but is depleted or missing in those with sinusitis. It is normal for a community of bacteria, viruses, fungi to live in the sinuses - this is the sinus microbiome.

My journey started in the winter of 2013 after reading research in late 2012 about L. sakei. I started with kimchi back then, but in the last few years I've used the product Lanto Sinus, which contains a kimchi-derived strain of Lactobacillus sakei.

Since starting this blog in 2013, I have heard from hundreds of people and the majority agree that L. sakei works great as a sinus treatment! Other probiotic species just don't work, even though they may help with some symptoms. [See Best Probiotics For Sinusitis for details on results and products used.]

Lessons Learned Over the Past Decade:

1) Lactobacillus sakei alone is enough to treat sinus infections or sinusitis. It helps with all the associated symptoms: mucus dripping down the throat (post-nasal drip), sinus pressure, sinus headaches, earaches and coughs from sinusitis, etc.

2) Using L. sakei (whether in kimchi or Lanto Sinus) should take about a minute! No fancy methods or protocols needed.

3) Only use L. sakei when needed. This means when there are sinus symptoms (e.g., lots of mucus, post nasal drip) or you're sliding towards sinusitis. No need to wait till the sinus infection is full-blown.

4) Stop using it when feeling better. Don't use it daily or as a preventive, but only when needed. There are many species of microbes living in the sinuses, so you don't want to flood the sinuses with just one species for weeks on end.

5) After using it for a few days, evaluate whether you can stop or whether you need to keep using it longer. The sinuses frequently keep improving and rebalancing after stopping L. sakei.  One can always use more if needed. ...continue reading "Ten Plus Years of Successfully Treating Sinus Infections With Probiotics"

Published on Leave a comment on Pesticides Involved in the Development of Parkinson’s Disease

For a while now it's known that exposure to pesticides is associated with developing Parkinson's Disease. But which pesticides? This is an important question because millions of pounds of pesticides are applied in the US each year. A recent study provides some answers.

The Harvard and UCLA Health researchers looked at 288 pesticides. They found that 53 pesticides were associated with Parkinson's disease, but 10 were directly toxic to dopaminergic neurons. Dopaminergic neurons are cells in the brain, and their degeneration and death play a key role in Parkinson's disease.

The 10 most toxic pesticides included four insecticides (dicofol, endosulfan, naled, propargite), three herbicides (diquat, endothall, trifluralin), and three fungicides (copper sulfate [basic and pentahydrate] and folpet). Some are commonly used even by homeowners, such as Preen (contains trifluralin) and Ortho Groundclear (contains diquat).

They also found that co-exposure to several pesticides (which typically happens) have a greater negative effect than just 1 pesticide.

Bottom line: There is much we don't know about pesticides, but studies are finding more health harms each year. Avoid using pesticides in your home, lawn, and garden if you can - especially unnecessary "cosmetic" lawn pesticides. Best and safest is to use nontoxic Integrated Pest Management (IPM) or organic.

Think of it this way: pesticides can give you cancer and damage your health, but clover and crabgrass can't.

Published on Leave a comment on Certain Foods Are Great For Gut Health

Another recent study confirmed that what you eat determines the microbes living in your gut (small intestines). This is the gut microbiome or microbiota (the community of bacteria, fungi, viruses). The microbes living in a person's gut can be determined by analyzing a sample of a person's poop.

The researchers found that persons eating more fruits, vegetables, and foods high in fiber (e.g., whole grains, fruits, vegetables, nuts, seeds) have gut microbes associated with health. They also have more diversity of species in the gut (this is a sign of health). But eat a diet rich in highly processed foods and low in fiber, and you'll have microbes associated with health problems (e.g., heart disease, cancer, diabetes).

The researchers point out that following the recommendations of the Dietary Guidelines for Americans (DGA) supports a healthy gut microbiome. Especially important for a healthy gut microbiome were vegetables, whole grains, legumes, and dairy. Yes, dairy foods have oodles of microbes (your cheese is alive!), whole fat dairy is beneficial, but skim milk or 0% is not. Eating a variety of high fiber foods is important because then you'll be eating a variety of fibers.

Bottom line: you are what you eat.

Excerpts from Medical Xpress: How diet quality affects the gut microbiota to promote health

We know that eating a healthy diet affects body weight, cholesterol levels, and heart health. A new study from the University of Illinois focuses on another component: the role of diet in supporting a healthy gastrointestinal microbiota.

Ready to eat some insects for your gut health? Hah! A recent research paper made the case that eating insects will improve the gut microbiome and health.

The researchers point out that eating insects already happens throughout the world. Edible insects are good sources of protein, micronutrients, and contain dietary fiber and omega-3 fatty acids. Also, insects can be farmed using fewer resources than conventional livestock (e.g., beef, pigs)

The most commonly consumed insects: beetles, caterpillars, wasps, bees, ants, grasshoppers, true bugs; and termites.

From Science Daily: Chitin from consuming insects can help both gut microbiota and global health

Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a paper co-authored by a Colorado State University researcher and published in Nature Food. ...continue reading "Are You Ready to Eat Insects?"

Well, the results of new research about skin with psoriasis compared to healthy skin isn't surprising. The research found that skin with psoriasis has a distinct microbiome (community of bacteria, viruses, fungi) - one that is different from that of healthy persons.

A main finding was that the types of bacteria were lower (less diversity) on the psoriatic skin. Greater diversity of bacteria is considered good - a sign of health. Levels of Staphylococcus were higher in the psoriatic skin, but healthy skin had higher levels of Cutibacterium and Kocuria.

Oher research also supports the view that microbes are somehow involved with the development of psoriasis. The hope is that someday treatment could be just taking a probiotic pill or applying certain microbes to the skin, perhaps in a lotion. Wouldn't that be great?

Excerpts from Medscape: Psoriasis and Psoriatic Arthritis Show Distinctive Skin Microbiomes

Published on Leave a comment on Pyrethroids and Autism Spectrum Disorder

A recent study may contribute to explaining why autism spectrum disorder (ASD) rates are rising so rapidly in the US. The CDC reports that 1 in 36 children have autism spectrum disorder as of 2020!! Researchers and physicians agree that things in the environment (e.g., pesticides) are playing a role in this increase.

Even though the study was conducted in mice, it examined the impact of pesticides called pyrethroids on neurological development. They found that even at low levels that humans are typically exposed to, there were neurological effects on mice who were exposed during pregnancy. Their behaviors were altered in a negative way, for example an increase in repetitive behaviors.

Pyrethroids are being used in increasing amounts in the US for all sorts of insect treatments, both inside and outside of homes. It's very frequently used against mosquitos. Studies find that 70 to 80% of the US population have pyrethroid breakdown products (metabolites) in the blood. This is because we are exposed to chronic low levels - whether in the air, in water, around our homes or workplace.

The researchers wrote in the published research that scientists are especially concerned with pyrethroid exposure because it has a harmful effect on fetal development in both humans and animals. Studies are finding links from pyrethroid exposure during pregnancy or infancy and developmental delays.

"Critically, evidence from recent epidemiology and longitudinal studies suggests that ambient prenatal exposure to pyrethroid pesticides poses a risk for autism, developmental delay, and neurodevelopmental disorders in general. Analysis of data from the CHARGE study showed a significant increase in risk for either ASD or developmental delay from exposure during pregnancy to pyrethroid pesticides being applied up to 1.5 km from the home. A regional study in New York showed an association between areas where aerial application of pyrethroid pesticides was used, and ASD and developmental delay prevalence in the area. Additionally, the presence of pyrethroid metabolites in blood or urine correlates with risk for ADHD in children."

Bottom line: Avoid using pyrethroids around the home and yard. Look into IPM (Integrated Pest Management) or organic and natural ways to deal with pests. Pyrethroids are also toxic to bees, and we need bees. Synthetic pyrethroids (which is what is commonly used) are not like natural extracts from the chrysanthemum flower, and don't let someone tell you they are.

A new study from The University of Toledo suggests early exposure to a common class of insecticides called pyrethroids may increase the risk of autism and other developmental disorders, even at levels currently recognized as safe by federal regulators. ...continue reading "Pyrethroids and Autism Spectrum Disorder"
