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. The researchers conclude that following the Dietary Guidelines for Americans (DGA) promotes a gut microbiota composition that may support overall health. ...continue reading "Certain Foods Are Great For Gut Health"

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.

Excerpts from Medical Xpress: Research links common insecticide to neurodevelopmental disorders

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"

It turns out that the baby gut microbiome is loaded with all sorts of viruses, and most of the species were unknown till now. All the viruses living in the gut is the virome. Analyzing baby poop is a way to find out what viruses live in the gut (intestines) of babies.

A team of scientists did an in-depth analysis of the poop (from diapers) of healthy one year old Danish children and found more than 10,000 new virus species! The overwhelming majority of the viruses are phages, which are viruses that attack and inhabit bacteria. There were many more viruses than bacteria in the baby poop.

Most of the phages are harmless, but some others are not so harmless, and this results in immune responses from the human host. In other words, all of this is normal and part of "training" the immune system in early childhood. The researchers named the newly discovered viruses after children participating in the study (e.g., Amandaviridae, Andyviridae).

By the way, it is normal for multitudes of viruses, bacteria, and fungi to live in the gut of humans throughout life - it's the gut microbiome.

Research involving Danish babies’ dirty diapers has provided a plethora of information on previously unknown viruses — and the best view yet of the makeup of the infant gut microbiome. ...continue reading "Healthy Babies Have Thousands of Viruses In The Gut"

Published on Leave a comment on Plant-Based Copies of Meat and Dairy Are Not the Same Nutritionally As Real Milk and Meat

Not all foods are equal. Especially dairy milk vs alternative "milks", such as almond or oat milks. Or plant-based "meat" vs animal meat. A recent study analyzed popular plant-based "milk" and "meat" products and found that they are not nutritionally equivalent to real milk and meat.

They contain different nutrients, amount of protein, calories, etc. The researchers concluded that eating only or mainly the plant-based substitutes can result in dietary deficiencies  - that is, of nutrients found in meat and dairy.

Meat and dairy products are good sources of vitamin B12, zinc, iodine, long-chain omega fatty acid, and choline. All of these are necessary for good health. Eating cheese (a dairy product) such as Jarlsberg cheese is great for bone health because of the microbes (Proprionebacterium freudenreichii) living in the cheese  and which produce vitamin K and DHNA (both necessary for bone health).

Instead of eating fake substitutes (many of which are highly processed, with lots of additives), why not focus on eating more real plant-based foods? This means eating more whole grains, seeds, nuts, legumes (beans), fruits, vegetables, and then just reduce the amount of meat and dairy eaten.

From Medical Xpress: Switching meat and milk for plant-based copies misses vital nutrients

Mitigating climate change is a key challenge of our time. One way many people try to reduce their greenhouse gas emissions is to eat less animal-source food—like meat and dairy—and instead eat more plant-based food. ...continue reading "Plant-Based Copies of Meat and Dairy Are Not the Same Nutritionally As Real Milk and Meat"

Women have long been drinking cranberry juice for prevention of urinary tract infections (UTIs), but medical studies have had variable results (some say cranberry juice and products help, while some others say they don't). A recent review of studies found that YES, cranberry juice and cranberry products help with prevention of UTIs.

The review was published in Cochrane Reviews, which is viewed as a gold standard in medical evidence. Fifty studies were reviewed, with the data supporting the use of cranberries (in juice, tablets, or capsules) in reducing the risk of developing UTIs.

Why do cranberries work? Cranberries contain proanthocyanidins (PACs), which inhibit E. coli from adhering (attaching) to the urothelial cells lining the bladder.

Another good treatment and preventative for the majority of UTI, is D-mannose (capsules or powder). D-mannose is effective for urinary tract infections caused by E. coli bacteria (up to 90% of UTIs), even infections that keep recurring (30 to 50% of infections). A study first found D-mannose effective in 2015, and since then there have been several studies finding D-mannose results to be "favorable".

From Medical Xpress: A myth no more: Cranberry products can prevent urinary tract infections for women

Drinking cranberry juice has long been a mythical prevention strategy for women who develop a urinary tract infection—and new medical evidence shows consuming cranberry products is an effective way to prevent a UTI before it gets started. ...continue reading "Cranberries Reduce the Risk of Developing Urinary Tract Infections"

Published on Leave a comment on Some Harmful Food Additives Could Finally Be Banned

Finally... two states (California and New York) are seeking to ban 5 chemicals frequently added to food that are known to cause health problems (cancer, neurological problems, hormone disruptors). They have no reason to be in food (and yes, safer alternatives exist). The five chemicals of concern are: red dye 3, titanium dioxide, potassium bromate, bromated vegetable oil, and propylparaben.

These additives are most commonly found in candy, baked goods, and soda. They are already banned in Europe. Once again the FDA is not protecting consumers, while Europe is way ahead of the US in protecting consumers. Of course the chemical industry is pushing back ($$ before consumer health!).

The bills are AB-418 Food product safety (California) and Bill S6055A - Prohibits certain food additives and food color additives (New York). If approved, both would go into effect in 2025.

Bottom line: Read ingredient lists on labels and avoid these 5 ingredients, plus as many other additives, preservatives, colors, artificial or natural flavors (all laboratory concoctions) as you can. Avoid ultra-processed foods and high-fructose corn syrup as much as possible. Best are ingredients that we all have in our kitchens.
