Published on Leave a comment on Kimchi Made With Seafood and Vegan Kimchi Contain the Same Microbes

Over the years I've received many questions about vegan versus kimchi that contains seafood. Are the microbes in the kimchi the same?

One reason this is an important question is because at certain stages of kimchi fermentation the beneficial bacteria Lactobacillus sakei (which treat sinusitis in many people) appears for a time. And during that time when L.sakei is present, dabbing a little kimchi juice in the nostrils helps and treats many individuals with sinusitis. Amazing, yes?

Many people prefer to treat sinusitis with vegan kimchi - which is also my personal preference. I don't want to worry about what is in the seafood used in kimchi. Therefore, it's vegan kimchi for me.

Earlier studies have suggested that even though kimchi is made with cabbage, the L. sakei grows from the surface of raw garlic used in making  the kimchi. From the M.A. Zabat et al (2018) study:

"Because kimchi is made without the use of a starter culture, the raw ingredients play a key role in establishing the bacterial community that is responsible for fermenting kimchi (Jung et al., 2011; Lee et al., 2015)".

"Large amounts of garlic are associated with more kimchi-associated LAB [lactic acid bacteria] in the final product (Lee et al., 2015)." [Note: L. sakei is one of the lactic acid bacteria in kimchi]

This is why the 2018 study, which I just read, is so interesting. The researchers found that both vegan (no seafood)and kimchi made with seafood (e.g., fish sauce) contain the same microbes after fermentation. They may have started out with different populations of microbes, but during fermentation the microbes become similar.

"We found that, despite initial differences in microbial composition between vegan and non-vegan kimchi, there was no notable difference in the final products. Ultimately, the microbial community of both vegan and non-vegan kimchi is dominated by Lactobacillaceae and Leuconostocaceae, and lacks the Enterobacteriaceae found in the fish sauce or miso paste."

Well... that's a relief. What kimchi you choose to eat and use as a sinusitis treatment is personal preference. It's all good. And yes, fermented foods such as kimchi are great for the gut microbiome. They increase gut microbial diversity (good!) and reduce inflammation.

From Physics News: Vegan and traditional kimchi have same microbes, study finds

Good news, vegans: A new study finds that kimchi made without fish products has the same type of bacteria as more traditionally made kimchi. That finding suggests that any "probiotic" benefits associated with traditional kimchi could be present in vegan versions as well. ...continue reading "Kimchi Made With Seafood and Vegan Kimchi Contain the Same Microbes"

Chronic wounds (wounds that won't heal) are a big health problem for many, many people. This past decade has seen all sorts of advances in chronic wound healing treatments, and now there is a future possibility of also applying probiotics on the wounds.

A recent study showed "proof of concept" that some Lactobacillus species are effective in eliminating biofilms and Pseudomonas aeruginosa on skin, which are big problems in chronic wounds. Proof of concept means that a preliminary study using laboratory tests (using "living skin" in a human skin model) showed that it can work, and should be tested further.

The researchers tested a treatment using several species of Lactobacilli (L. acidophilus, L. casei, L. rhamnosus). They found that probiotics added to a modern wound dressing that contained silver did better at eradicating biofilms than using silver containing dressings alone or probiotics alone. (Note: Lactobacillus species are generally viewed as beneficial bacteria, and many Lactobacillus species live at different sites in the human microbiome, which are communities of fungi, bacteria, and viruses.)

The interesting part is that the species picked for the research were because they were in supplements readily available. The researchers cited research showing other Lactobacillus species also having potential in wound treatment, especially due to effects of their lactic acid.

It's an exciting time! Stay tuned to see if probiotic infused dressings actually work on chronic wounds in live human beings...

From Physics News: A living bandage: Wound dressing uses probiotic bacteria to combat biofilms

Millimeter by millimeter, new tissue makes its way through a wound until it has closed a skin lesion. Soon, in the best case, there is nothing left to see of a knee scrape, a finger cut or a burn blister. Not so with chronic wounds, though: If the injury has not healed after four weeks, there is a wound healing disorder. Sometimes, seemingly harmless tissue damage can develop into a permanent health problem or even blood poisoning.

Something important for parents to know about: Milks marketed to parents as "toddler milks" are unnecessary, are unregulated, don't offer any benefits over regular milk, and are nutritionally lacking . This statement is from the American Academy of Pediatrics (AAP) report, which was issued Oct. 20, 2023.

The "toddler milks" are found everywhere, frequently next to infant formulas on grocery shelves. They generally come in powdered form and are marketed as being for toddlers and children up to the age of 3. They are nutritionally incomplete and also contain too much salt and sugar.

The AAP says that children 1 years and older should be given a balanced diet of solid foods, breast milk (optional), and  pasteurized cow's milk. That's it. No need for so-called toddler milks.

By the way, infant formulas have to meet federal guidelines, but NOT these so-called "toddler milks". One researcher pointed out that they are just "gateway sugary drinks", and nutritionally inferior to ordinary milk and a balanced diet.

Bottom line: The manufacturers make unproven claims that are not true. They just want your money. $$$ Ignore them!

From Medical Xpress: So-called toddler milks are unregulated and unnecessary, a major pediatrician group says

Powdered drink mixes that are widely promoted as "toddler milks" for older babies and children up to age 3 are unregulated, unnecessary and "nutritionally incomplete," the American Academy of Pediatrics warned Friday. ...continue reading "Pediatricians Say to Avoid Giving Toddler Milks to Young Children"

Published on Leave a comment on Try Exercise First For Erectile Dysfunction

Erectile dysfunction is a serious problem for many men, especially as they get older. A review and analysis of 11 well-done studies  looking at whether exercise helps with erectile dysfunction found that YES, it does.

They found that exercising for at least 30 minutes three times a week can be just as effective as Viagra and Cialis at improving erectile dysfunction (ED). Also, the worse the ED at the start of a study, the more exercise helped.

What were the exercises? Any aerobic activities that got the heart pumping, such as cycling, tennis, or brisk walking. In the studies looked at, the exercise sessions were typically 30 to 60 minutes, and occurred 3 to 5 times a week. Some studies had the men exercise on their own, while other studies had the men attend supervised exercise sessions.

Bottom line: Exercise improved ED in all men! It didn't matter what the men weighed, their medication use - it helped them all. (Examples of earlier studies looking at exercise and physical activity helping improve ED.)

This could be because ED is considered a measure of a man's overall heart health. When there is heart disease, inflammation, and narrowing or hardening of the arteries - then ED increases. Physical activity, on the other hand, improves health, including heart disease.

Exercising for at least 30 minutes three times a week can be just as effective as Viagra and similar medications at improving erectile function, according to a new analysis of the best research to date on aerobic exercise and erectile function. ...continue reading "Try Exercise First For Erectile Dysfunction"

Published on Leave a comment on The Vaginal Microbiome

We have microbiomes all over our bodies. Millions of microbes in communities - for example, the ear, the sinuses, the skin, the gut, and on and on. Women also have a vaginal microbiome. When the microbiome of the vagina gets disrupted, health effects such as bacterial vaginosis (BV) can occur.

The Scientist recently published a good article on the vaginal microbiome, as well as the microbes in the vagina associated with health and those associated with health problems. [Note: All these microbes live together in a healthy vaginal microbiome - it's just that sometimes the balance gets disrupted.] Much has been learned since they first wrote about the microbiome of the healthy vagina in 2014 - but much is still unknown.

Some good news is that the beneficial bacteria Lactobacillus crispatus, which is very important for a healthy vagina, is now easily available as a probiotic supplement (to be taken when needed) in the US. Back in 2016 it was only available in Europe for BV and urinary tract infections (UTIs). This bacteria has been referred to as the "golden child of all the lactobacilli" in the vaginal microbiome.

Excerpts from The Scientist: The Vaginal Microbiome is Finally Getting Recognized

Vaginal dysbiosis has long been a taboo subject, but studying and optimizing the vaginal microbiome could be a game changer for women's health. ...continue reading "The Vaginal Microbiome"

Published on Leave a comment on Organic Foods From Other Countries May Not Be Organic

Many consumers don't realize it, but some (many?) of the countries that flood the US market with "organic" foods are actually committing fraud. The so-called organic foods are not organic, but are conventionally grown and the documents saying they are organic have been purchased for a price.

The investigative group Organic Eye that monitors the organic industry, including looking for fraud, has filed a lawsuit about this issue.

Many organic imported foods from places like China, Brazil, and Turkey are actually not organic, and this is why their "organic" foods are so inexpensive compared to foods grown by legitimate organic farmers here in the US. The Washington Post and others have written about the fraud. Buyer beware!

Yes, buy organic foods as much as possible, but try to buy organic foods grown and produced in the US, Canada, the European Union - and also from local farmers.

Excerpts from Organic Eye: Lawsuit Alleges Violation of Federal Law and a Green Light for Fraud - US Family Farmers Competitively Damaged, Consumers Deceived

Eugene, Ore. — When Oregon organic hazelnut grower Bruce Kaser started looking into why organic hazelnut imports from Turkey were priced so low, close to conventional hazelnuts, he found he was pulling on a thread that had the USDA certification of foreign commodities unraveling. His research exposed a systemic, conflict-ridden scandal, and led to the filing of a federal lawsuit on October 17 against the USDA, alleging a breach in the intent of Congress’ Organic Foods Production Act (OFPA). ...continue reading "Organic Foods From Other Countries May Not Be Organic"

Published on Leave a comment on Toxic Chemicals Are On Many Of the Clothes We Wear

It turns out that the fabric used to make clothing is doused with all sorts of chemicals. Synthetic fabrics, fabrics dyed with azo dyes, and all fabrics treated to be stain repellant, anti-mold, anti-odor, wrinkle free, easy care, water resistant, flame retardant are the worst. Alden Wicker's book To Dye For: How Toxic Fashion Is Making Us Sick - And How We Can Fight Back discusses this topic in depth.

To give fabric performance qualities, lots of toxic chemicals have to be used, including endocrine disruptors and PFAS. There is no regulation of all the chemicals used on fabrics, which means we are exposed to them when we wear clothing. And yes, people are getting sick from the fabrics, especially if they have to wear them as part of their job. For example, flight attendants and firefighters.

The book is both fascinating and horrifying. I started it one morning and found myself neglecting everything else that day - just reading and reading till I was done that evening. Interesting stories (especially what flight attendants went through with new toxic uniforms), very thorough, things you can do to protect yourself, and lots of references at the end if you want to pursue the topic further.

What you can do: Try to wear natural fabrics (cotton, linen, hemp, wool). Avoid clothes that are stain repellent, anti-mold, anti-odor, wrinkle resistant, and flame retardant. Look for Oeko-Tex and GOTS organic certification, if possible - even though only a limited number of the many toxic chemicals are tested for.

Published on Leave a comment on Daily Walking Up Stairs Lowers the Risk of Heart Disease

We've known for a while that exercise and physical activity lower the risk of developing heart disease. It turns out that a good exercise that many of us do in the course of ordinary life is walking up and down stairs. Yes, that counts!

A large study (458,860 adults) used data from the UK (Biobank). They found that walking up 5 flights of stairs (about 50 steps) daily was associated with a 20% lower risk of developing heart disease (including ischemic strokes) after 5 years.

Interestingly, persons who were stair climbers at the beginning of the study, but then stopped at some point during the 5 year length of the study had a higher risk of heart disease than those who never climbed stairs.

Bottom line: Walk up stairs whenever you can. It's good for your heart!

From Science Daily: Walking more than five flights of stairs a day can cut risk of heart disease by 20 percent, study says

Forget walking 10,000 steps a day. Taking at least 50 steps climbing stairs each day could significantly slash your risk of heart disease, according to a new study from Tulane University. ...continue reading "Daily Walking Up Stairs Lowers the Risk of Heart Disease"

Americans take a lot of prescription drugs, so many that it has reached historic highs. 6.3 billion prescriptions were filled in 2020! According to a recent study, it appears that the number of prescription drugs a person takes over the life span will only increase.

Research conducted by Jessica Y. Ho at Penn State University found that persons born in 2019 could be expected to take prescription drugs for about half their lives: 47.54 years for women and 36.84 years for men. Also, the number of years individuals can expect to take 5 or more drugs has increased substantially.

Some of the big increases in prescription drug use are from statins, antihypertensives, and antidepressants. There are ethnic and racial differences in prescription drug use, with non-Hispanic Whites taking the most.

From Science Daily: Americans will spend half their lives taking prescription drugs, study finds

An American born in 2019 will spend a larger share of their lifetime taking prescription drugs than being married or receiving an education, according to new research by Jessica Ho, associate professor of sociology and demography at Penn State. She found that American males will spend approximately 48% of their lives taking prescription drugs. The number jumped to 60% for females. ...continue reading "Americans Take Record High Numbers of Prescription Meds, and This Is Projected to Increase"

Published on Leave a comment on Some Habits For Living A Longer and Healthier Life

There is tremendous interest in how to live a long and healthy life. This means trying to avoid getting diseases that so many suffer from as they age, such as diabetes, heart disease, and dementia. What diets are best? What kind of lifestyle?

NPR published a recent article about 7 daily habits linked to living a longer, healthier life, using information from Dan Buettner's work on blue zones. Scientific research supports the importance of these habits, especially good nutrition (for example, the Mediterranean diet) and physical activity.

The blue zones are communities throughout the world in which there are a lot of centenarians (people living to 100 years or more). What is important is that the people in these communities are aging with good health, and leading active and fulfilling lives - without dementia, and not in nursing homes.

The diets vary from place to place, but all avoid fast foods and highly processed foods. Instead, a lot of vegetables, fruits, whole grains, legumes (beans), and nuts are eaten. Little meat. Food is cooked at home. By the way, this type of diet is associated with a good gut microbiome, and generally a good gut microbiome goes with good health.

Unfortunately, these blue zone areas are now fading, due to changes in lifestyles  - fast food, etc. But a few other places are stepping up, trying to make living spaces healthier and incorporating what has been learned about health and longevity - for example, Singapore.

Bottom line: Research shows a diet rich in plant-based foods (whole grains, fruits, vegetables, nuts, seeds, legumes), plenty of sleep, lots of movement (physical activity), and a sense of purpose in life are all important in aging well.

Excerpts from correspondent Allison Aubrey article at NPR: 7 habits to live a healthier life, inspired by the world's longest-lived communities

At a time when life expectancy in the U.S. has dipped and diet-related disease is a leading cause of death, it's no wonder that Dan Buettner's decades-long exploration of centenarians who thrive in the longest-lived communities on Earth is attracting lots of attention. ...continue reading "Some Habits For Living A Longer and Healthier Life"
