Many studies are finding that eating ultra-processed foods (UPFs) can lead to all sorts of health problems. A recent large study conducted in France found that people eating higher amounts of food preservatives had a higher risk of type 2 diabetes. Overall, people consuming foods with higher amounts of preservatives had a 47% higher risk of developing type 2 diabetes (when compared to people eating low amounts of preservatives).

Over 100,000 French adults were followed for more than a decade. The researchers found that 58 preservatives were in the foods they ate. The researchers examined 17 preservatives in depth (the most common ones eaten) and found that 12 preservatives are linked to type 2 diabetes: potassium sorbate, potassium metabisulphite, sodium nitrite, acetic acid, sodium acetates, calcium propionate, sodium ascorbate, alpha-tocopherol, sodium erythorbate, citric acid, phosphoric acid, and rosemary extracts.

Bottom line: Read ingredient lists on food labels. Avoid foods that contain ingredients with chemical sounding names that are not normally found in a home kitchen. Those ingredients are in ultra-processed foods. Additionally, "natural flavors" are laboratory concoctions (found in ultra-processed foods).

People who consume higher amounts of food preservatives may face a greater risk of developing type 2 diabetes, according to a large new study. Preservatives are commonly added to processed foods and beverages to extend shelf life. ...continue reading "Food Preservatives Linked to Higher Risk of Type 2 Diabetes"

Published on Leave a comment on Garlic Extract Mouthwash Appears Promising

There has been discussion over the years regarding mouthwash - what are the harms and benefits? Does using mouthwash regularly disrupt the oral (mouth) microbiome? Chlorhexidine mouthwash is generally considered the best for treating gingivitis and killing bacteria.

Researchers at the College of Dental Medicine, Univ. of Sharjah in the UAE, recently published a review of studies comparing garlic extract mouthwash vs chlorhexidine mouthwash. They found that garlic mouthwash can be as effective as chlorhexidine mouthwash.

Garlic (Allium sativum) has natural antimicrobial properties. The researchers found that among the studies there were some differences in effectiveness for both types of mouthwash depending on the concentration used and duration of application.

However, one negative they found is that garlic mouthwash can be more uncomfortable to use - it can cause a burning sensation and unpleasant taste.

Excerpts from Science Daily: Garlic mouthwash shows shockingly strong germ-fighting power

Garlic extract has been found to offer antimicrobial effects that are on par with commonly used antiseptics and disinfectants such as chlorhexidine, according to medical researchers at the University of Sharjah.

The study, published in the Journal of Herbal Medicine, reports that garlic-based mouthwash may produce more discomfort than chlorhexidine but appears to provide longer-lasting residual activity.

Published on Leave a comment on Coffee and Liver Health

The health benefits of regularly drinking coffee keep increasing. A recent study confirmed that consuming coffee on a regular basis reduces the incidence of liver disease and slows the progression of several liver diseases.

The study authors write that coffee contains a number of bioactive compounds (e.g., caffeine, polyphenols, diterpenes) which have "anti-inflammatory, antioxidant, antifibrotic, and anticancer properties".

In other words, enjoy your daily coffee. It's good for you!

Excerpts from Medscape: Regular Coffee Drinking Can Protect and Restore Liver Health

TOPLINE: Several bioactive compounds in coffee exert antioxidant, anti-inflammatory, antifibrotic, and metabolic effects that reduce the incidence and progression of liver diseases. ...continue reading "Coffee and Liver Health"

For a few years there have been reports and research of hair straightening chemicals causing health harms, specifically kidney damage. Even kidney failure. Yet the use of these dangerous products continues in a number of countries, including the US, France, and Israel.

The problem appears to be the glyoxylic acid in some hair-straightening products. Bottom line: Read the ingredient lists on hair straightening products and avoid those with glyoxylic acid.

Excerpts from The Times of Israel: 17-year-old girl hospitalized for kidney failure after hair-straightening treatment

A 17-year-old girl who underwent a hair-straightening treatment was hospitalized with severe kidney failure at Shaare Zedek Medical Center, the hospital reports.

Another woman, 25, also suffered from kidney failure caused by hair straightening a little over a month ago. ...continue reading "Hair Straighteners Continue to Cause Kidney Harm"

Published on Leave a comment on High Fat Cheese and Lower Risk of Dementia

Great news for cheese lovers! A recent study found regularly eating full-fat (high-fat) cheese and cream was associated with a lower risk of developing dementia. Some examples of full-fat cheese include cheddar, Swiss, Parmesan, Brie, Gouda, Provolone, Colby, Havarti, Mozzarella (full-fat), and cream cheese.

This was a long-running study (27,670 persons for 25 years) conducted in Sweden. High-fat cream and cheese consumption was inversely associated with dementia, Alzheimer's disease, and vascular dementia. Eating more than 50 grams (about 1/3 cup or 2 slices) of full-fat cheese per day was associated with a 13% to 17% lower risk of Alzheimer's, and more than 20 grams (about 1 1/2 tablespoons) of full-fat cream was linked to a 16% lower risk of dementia overall.

However, consumption of low-fat cheese, low-fat cream, milk (low or high fat), and butter showed no association with dementia.

Published on Leave a comment on Pesticide Exposure Greater In Conventional Farmers Than Organic Farmers

It turns out that wearing silicone wristbands is a great way to measure a person's exposure to pesticides that are inhaled or absorbed in the skin - whether you are  farmer, living near pesticide treated farm fields, a pet owner, or a member of the general population (consumer). Another source of pesticides is food and water, but the silicone wristbands don't measure that.

A recent European study, using the silicone wristbands, found that conventional (non-organic) farmers are exposed to the greatest number and concentration of pesticides, followed by organic farmers and farm neighbors, and the fewest in ordinary consumers (the general population). The wristbands revealed that pesticide use, whether as a farmer or in the home, and having pets predicted greater pesticide exposure.

The researchers looked for the presence of 193 pesticides and found 172 of them. People are typically exposed to mixtures of pesticides. Keep in mind that many pesticides banned in the European Union are not banned in the US, and are routinely used in the US.

Pesticide use, whether as a conventional farmer or in the home, and having pets predicted a greater pesticide exposure. Organic farmers had  lower levels of pesticides, and were exposed to fewer pesticides than conventional (non-organic) farmers. This is because organic farmers are not allowed to use the many pesticides that are routinely used by conventional (non-organic) farmers.

A nice summary of the research from Beyond Pesticides: Lower Pesticide Exposure Documented For Organic Farmers, Elevated For Others

Published in Environment International, a study utilizing silicone wristbands provides a snapshot of chemical exposure in over 600 participants across 10 European countries. Using the wristbands as passive and noninvasive samplers, the researchers find that organic farmers’ wristbands contain lower pesticide levels than other groups, offering insight into the benefits of organic and disproportionate risks to farmers using chemical-intensive methods. The results further reveal prevalent environmental pesticide mixtures, in addition to highlighting exposure to current-use pesticides (CUPs) and legacy (banned) pesticides that occurs through multiple exposure routes to workers, residents, and consumers. ...continue reading "Pesticide Exposure Greater In Conventional Farmers Than Organic Farmers"

Worried about being exposed for years to sofas filled with flame retardants? The dust from the foam in these sofas release flame retardants into the air, which then get into people's bodies. Flame retardants are linked to all sorts of health problems (cancer risk, hormone disruption, and neurodevelopmental effects). But finally, there is some good news.

A recent study found that just one year after getting rid of old flame retardant filled sofas and chairs (and replacing them with flame retardant-free furniture) resulted in a huge decline in flame retardant polybrominated diphenyl ethers (PBDEs) in the body. The levels of PBDEs declined in half in 1.4 years.

The use of use of organophosphate flame retardants (OPFRs) in foam products (e.g., the foam in upholstered furniture) is also declining in upholstered furniture, but the levels in the study participants didn't decline as much. This is perhaps because OPFRs are still used today in many other products (e.g., as a plasticizer, a coating for electronic devices, in car furnishings).

Bottom line: When buying new sofas and upholstered chairs, look for flame-retardant free furniture. A label commonly on the bottom of the furniture will tell you if they contain flame retardant chemicals or not. [NOTE: Upholstered furniture made between 1970 and 2014 probably contains flame retardants.] Also, wash hands before eating. Vacuum with a HEPA filter.

From Medical Xpress: Swapping old sofas and chairs reduces body levels of harmful flame retardants

New research led by the California Department of Public Health and partners has found that replacing foam-containing furniture made before 2014 would cut in half levels of certain harmful flame retardants in people's bodies in just over a year.

Published in Environmental Pollution, the study is the first to show measurable health benefits from California's 2014 furniture flammability standard update, which made it possible for manufacturers to comply without adding chemical flame retardants. ...continue reading "Flame Retardant Levels In the Body Go Down When Old Sofas Are Replaced"

When looking at the research, it is striking that so many chemicals that we are exposed to daily are harming us. Health harms include an increase in certain cancers (e.g., brain cancer and leukemia from certain pesticides) and reproductive effects. This can be seen clearly when research shows that sperm counts are declining globally 2.64% per year since 2000.

A recent report from HEAL (Health and Environmental Alliance in the European Union) found that along with this, infertility rates, testicular cancer, and prostate cancer are increasing. This is alarming!

HEAL’s report (author Dr. Cannarella) details alarming indications of catastrophe in male reproductive health: prostate cancer, testicular cancer, crashing sperm counts, infertility, and numerous developmental problems including cryptorchidism, urogenital malformations, and hypospadias. The report highlights pesticides, microplastics, phthalates, bisphenols, PFAS and heavy metals as the likely environmental sources of the crisis. There is evidence that all of these endocrine disrupting chemicals (EDCs) adversely affect male reproductive function.

Excerpts from the latest research on the drop in sperm counts globally and declines in male reproductive health, the science report from HEAL: Chemical pollution and men’s health: A hidden crisis in Europe

A 2023 meta-analysis by Levine et al. showed that global sperm counts declined by 52% between 1973 and 2018. European countries showed similar or even steeper declines, especially in Western and Southern Europe. ...continue reading "Male Sperm Counts Continue to Decline"

Published on Leave a comment on Some Foods May Protect Us From the Harms of Too Much Sitting

We all know sitting too much is not good for our health. But for many of us, it's our reality - sit all day at work, and then come home and relax by sitting all evening. But there is some good news. A recent study found that eating foods rich in flavanols, such as cocoa,  may protect our blood vessels from the harms of too much sitting.

While the research occurred in young healthy men (with either high or low levels of fitness), all had detrimental effects in their vascular health (blood flow) after several hours of sitting. Drinking a flavanol rich cocoa drink at the beginning of a 2 hour sitting time prevented the decrease in blood flow ("sitting-induced vascular dysfunction") in both upper and lower limbs.

The researchers did point out though, that some exercise every hour, even 5 minutes of walking or climbing stairs, would have the same effect.

Flavanols are naturally occurring polyphenols found in various fruits (e.g., blueberries, apples, grapes), green and black tea, matcha, nuts, red wine, and cocoa beans. They have previously been linked to cardiovascular benefits, including support for the vascular system during psychological stress. Eating diverse flavanoid rich foods is best because there are so many types of flavanols.

From Science Daily: Cocoa and tea may protect your heart from the hidden damage of sitting

New findings from the University of Birmingham suggest that regularly eating foods rich in flavanols, including tea, berries, apples, and cocoa, may help protect men's blood vessels from the negative effects that occur during long periods of sitting. ...continue reading "Some Foods May Protect Us From the Harms of Too Much Sitting"

Published on Leave a comment on The Foods You Eat and Their Link to Constipation

For years it has been known that increasing the amount of fiber (and drinking enough fluids) in a person's  diet helps to prevent constipation. A recent large multi-year study of 96,000 adults confirmed this: Mediterranean and plant-based diets prevented constipation, and Western and inflammatory diets (low fiber, high ultra-processed foods) raised constipation risk.

Vegetables, cruciferous vegetables (e.g., broccoli), legumes (beans, lentils, chickpeas), and fruits were all associated with reduced risks for constipation. High vegetable and nut consumption was especially good for preventing constipation. Additionally, a low carbohydrate diet showed a slight increased risk for constipation. Eating a diet rich in cereal fibers (e.g., white bread, low fiber breakfast cereals) and ultra-processed foods was linked to constipation.

Besides reducing constipation, many studies show that eating a diet rich in fruits, vegetables, whole grains, seeds, nuts, legumes, such as the Mediterranean diet, is protective for cardiometabolic diseases (e.g., heart disease, heart attack, strokes, kidney disease, and type 2 diabetes), cancer, and even early death. This type of diet is high in fiber, has positive effects on the gut microbiome, and reduces chronic inflammation.

From Science Daily: What 96,000 adults taught scientists about preventing constipation

Chronic constipation becomes more common with age. Researchers from Mass General Brigham conducted a new study examining whether five widely followed diets could help prevent chronic constipation in middle- and older-age adults. The team monitored more than 96,000 participants for several years to see how long-term eating habits influenced the likelihood of developing this persistent gastrointestinal issue. Their analysis showed that people who routinely ate a Mediterranean or plant-based diet experienced a lower incidence of constipation. The findings appear in Gastroenterology. ...continue reading "The Foods You Eat and Their Link to Constipation"
