Many studies are finding the existence of microplastics everywhere in the environment and in our bodies. Microplastics occur when plastic items degrade over time. A recent study confirmed that drinking from plastic water bottles is a major source of the microplastics and nanoparticles that we ingest.

Microplastics are 1 µm to 5 mm in size and nanoplastics are even smaller (less than 1 µm).  They are usually invisible to the naked eye.

Study researchers did a review of over 141 studies and concluded that the average person ingests 39,000 to 52,000 microplastics each year, and those who drink bottled water ingest about 90,000 more particles than persons only drinking tap water.

Research on long-term health impacts (if any) of ingesting and breathing in microplastics and nanoparticles is just starting, but what has been done is concerning - at a minimum they are causing inflammation in our bodies. Other research suggests numerous health effects (e.g., respiratory issues, reproductive problems, disruption of the immune system).

Bottom line: buy, drink, and store as beverages in glass bottles, and drink tap water. Avoid single-use plastic water bottles.

The sun-drenched paradise of Thailand's Phi Phi islands isn't the usual starting point for a Ph.D. But for Sarah Sajedi, those soft, sandy beaches—or rather, what she found under them—inspired her pivot from a business career to an academic one. ...continue reading "Bottled Water A Major Source of Microplastics and Nanoparticles"

Stress can have harmful health effects on the body, including the gut microbiome. A recent article in the medical site Medscape reviewed studies of chronic stress and the gut microbiome and found that chronic stress alters the gut microbiome, resulting in gut dysbiosis (the gut microbial community is imbalanced or out-of-whack).

For example, researchers have found alterations in gut microbes, less diversity of microbes, and fewer numbers of certain beneficial microbes  in those with PTSD (post-traumatic stress disorder).

Interestingly, the researchers stress that a good diet (e.g., Mediterranean diet, including fermented foods) will help the gut microbiome, but that there isn't any evidence for probiotic supplements. In other words, don't take store-bought daily supplements, but instead focus on eating well, exercise, and getting enough sleep.

From Medscape: How Chronic Stress Disrupts the Gut Microbiome

Chronic psychological stress is common. A 2023 survey revealed that about one quarter of US adults reported high stress levels, and three quarters reported that chronic stress affects their daily lives.

Emerging evidence suggests that chronic stress not only exacts a high toll on mental health but also can wreak havoc on all levels of gastrointestinal (GI) functioning, all the way down to the microbiome. ...continue reading "Chronic Stress and the Gut Microbiome"

Many people suffer from intestinal ailments, such as intestinal bowel diseases and intestinal bowel syndrome. Over and over researchers find that altered gut microbiomes and intestinal lining alterations (e.g., "leaky gut") may be involved. A recent study from MIT found that the amino acid cysteine  promotes healing of the small intestinal lining.

Once again, a person's diet may be the answer. Cysteine is found in many high-protein foods. Foods that are rich in cysteine include: poultry, eggs, beef, fish (e.g., salmon, halibut, tuna), whole grains, soybeans, and some nuts (almonds).

While the study was conducted in mice, the researchers felt the results also applied to humans.

From Medical Xpress: A cysteine-rich diet may promote regeneration of the intestinal lining

 A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune signaling pathway that helps stem cells to regrow new intestinal tissue.

This enhanced regeneration may help to heal injuries from radiation, which often occur in patients undergoing radiation therapy for cancer. The research was conducted in mice, but if future research shows similar results in humans, then delivering elevated quantities of cysteine, through diet or supplements, could offer a new strategy to help damaged tissue heal faster, the researchers say. ...continue reading "Healing the Small Intestine and the Amino Acid Cysteine"

Published on Leave a comment on Study Finds Reason To Take Vitamin D3 and Not Vitamin D2

For years the medical advice has been that when taking vitamin D supplements, make sure it is the vitamin D3 form and not vitamin D2. The reasons given are that vitamin D3 is absorbed better and has more health benefits. A recent study found that there is an even better reason for taking vitamin D3 and not vitamin D2. It's because vitamin D2 actually lowers vitamin D levels in the blood.

From Medical Xpress: Vitamin D3 concentrations are lowered by a common vitamin D supplement

Taking vitamin D2 might lower the body's levels of the more efficient form of vitamin D, vitamin D3, according to new research from the University of Surrey, John Innes Center and Quadram Institute Bioscience. Many people take vitamin D supplements to support their bone and immune health and meet the UK government recommendation of 10 micrograms (µg) each day, especially during the winter months.

There are two forms of vitamin D supplements available: vitamin D2 and vitamin D3. Researchers have found that taking vitamin D2 supplements can lead to a drop in the body's concentration of vitamin D3, which is the form our bodies naturally produce from sunlight and use most effectively to raise overall vitamin D levels. ...continue reading "Study Finds Reason To Take Vitamin D3 and Not Vitamin D2"

Microplastics (teeny tiny plastic particles) have been detected all around us in the environment, our food, even our organs (e.g., lungs, blood, brain, placentas). Wherever we look, they are found in our bodies, with a recent study finding them in our bones.

The big question is: are these microplastics having a harmful effect on us? The researchers, who reviewed 62 studies, found that yes, microplastics could be harming bone health a number of different ways. They may be weakening our bones, impairing the function of bone marrow stem cells, accelerate cell aging, and could be worsening metabolic bone diseases like osteoporosis.

Microplastics occur as plastic items degrade over time. We breathe microplastics in, eat them (in our food), and drink them in (in water and other liquids). We can't avoid them totally, but we can cut down the amount we are exposed to and ingest - for example, not drinking bottled water (a big source of microplastics), and reducing the amount of plastic furniture, synthetic fabric (e.g., polyester), and synthetic rugs and flooring (e.g., vinyl) in our homes. Also, avoid playing on synthetic turf in playing fields and parks.

From Science Daily: Scientists discover microplastics deep inside human bones

The production and use of over 400 million tons of plastic each year has polluted beaches, rivers, and even the deepest parts of the ocean, reaching depths of up to 11,000 meters. In addition to visible environmental impacts, plastic contributes to climate change. It is estimated that plastic production generates 1.8 billion tons of greenhouse gases per year. Scientific evidence also suggests that using plastic materials in everyday life has impacted human health.

A large number of plastic particles detach from curtains, furniture, clothing, and other plastic objects. These particles remain suspended in the air, dissolve in drinking water, adhere to food, and can be inhaled, ingested, or come into contact with people's skin. Consequently, scientists have found microplastics in blood, the brain, the placenta, breast milk, and human bones.

Individuals with psoriasis are always looking for ways to improve the inflammatory skin disorder, especially natural ways. A recent small study found that following a Mediterranean diet is a simple and effective way to reduce the symptoms of psoriasis (red, scaly patches and persistent itching).

Subjects with mild to moderate psoriasis were randomly assigned to one of 2 dietary groups. The group following a Mediterranean diet for 16 weeks had significantly reduced psoriasis severity and symptoms, when compared to the control group that were just told to follow a low-fat diet. Almost half of the Mediterranean group had a 75% reduction of psoriasis severity and symptoms! None of the low-fat diet group had a reduction in psoriasis severity and symptoms.

Additionally, all persons in the study were using their usual topical therapy for their psoriasis. The improvements in the Mediterranean diet group occurred without significant weight loss.

The Mediterranean diet is rich in fruits, vegetables, whole grains, seeds, nuts, legumes, fish, and olive oil. In the study's Mediterranean diet group, the participants were not only given nutritional advice, but also a weekly provision of extra virgin olive oil. This diet is anti-inflammatory, which is why it may be so beneficial to those with psoriasis.

Medical Xpress: Mediterranean diet leads to 75% symptom reduction in patients with mild to moderate psoriasis

Over 60 million people worldwide are affected by psoriasis, a chronic inflammatory skin disorder that causes red, scaly patches and persistent itching. A new study has found that following a Mediterranean diet—rich in plant-based foods, extra-virgin olive oil, and a moderate amount of fish, and poultry—could provide relief to psoriasis symptoms.

A recent study found that there is an increased risk of blood cancers occurring in  children who receive X-rays and CT scans. And as the number of X-rays and CT scans go up (thus an increase in total cumulative dose of radiation), the risk of a blood cancer also increases.

The researchers refer to these increased number of cancers as "radiation-induced hematologic cancers". These include such cancers as  lymphoid cancers, leukemia, and histiocytic- or dendritic-cell cancers. They estimated that the number of these radiation-induced cancers is 1 in 10 blood cancers in children.

They advise only getting X-rays and CT scans if necessary, and consider getting an MRI or ultrasound instead (if possible).

From Medical Xpress: Study finds 10% of pediatric blood cancers may stem from medical imaging radiation

A study led by UC San Francisco and UC Davis has concluded that radiation from medical imaging is associated with a higher risk of blood cancers in children.

The researchers examined data from nearly 4 million children and estimated that one in 10 blood cancers—some 3,000 cancers in all—may be attributable to radiation exposure from medical imaging. The risk increased proportionally based on the cumulative amount of radiation the children received. ...continue reading "Medical Imaging Radiation and Increased Risk Of Blood Cancers In Children"

Published on Leave a comment on Study Finds That Patient Care Suffers When Private Equity Takes Over A Hospital

It's what many suspected. Once private equity firms take over a hospital, patient care suffers.

A recent study found that in hospitals acquired by private equity firms, the patient death rate in emergency departments increases, and there is an increase in patient transfers to other hospitals.

It is thought that this is due to cuts in staffing and salary cuts. Other cuts (equipment? supplies?) may also be occurring.

It appears that rather than patient care, profits are #1 to private equity firms.

After hospitals were acquired by private equity firms, patient death rates in the emergency departments rose by 13% compared with similar hospitals, according to research published this week in Annals of Internal Medicine.

The research, which compared outcomes at hospitals over a 10-year period, adds fresh evidence to previous studies showing harmful patient outcomes and higher costs among health care entities owned by profit-oriented financiers.

Skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma) rates are rising. Skin cancer is the most common cancer in the U.S., with current estimates that 1 in 5 Americans will develop skin cancer in their lifetime. Unfortunately, a person can get repeat skin basal cell and squamous cell cancers. Yikes!

Interestingly, since 2015 studies are finding that a form of vitamin B3 called nicotinamide are a skin cancer preventive (chemopreventive) medication. That is, taking nicotinamide supplements reduces the risk of basal cell and squamous cell cancer development.

A recent study found that persons who already had one skin cancer removed, can significantly reduce the risk of a second skin cancer occurring if they ingest 500 mg of nicotinamide two times daily for more than one month. An overall 54% reduction in another skin cancer occurring in this group!

The biggest reduction of another skin cancer occurring was in those who had a squamous cell carcinoma removed. However the preventive effect was reduced in those who already had multiple (2 or more) skin cancers.

Excerpts from NPR: Vitamin B3 can help protect against skin cancer. Here's who may benefit

Doctors who perform skin cancer surgeries often recommend nicotinamide — which is a form of Vitamin B3 — to their patients. It's been shown to protect cells from UV radiation damage. ...continue reading "Taking Vitamin B3 Reduces the Risk of Another Skin Cancer"

Published on Leave a comment on Common Foods Linked to Improved Heart Function

The evidence keeps piling up that certain foods are associated with health, while other foods (e.g., soda, ultra processed foods) are associated with chronic diseases. A recent article reported the results of several studies finding certain foods linked to cardiovascular health, including lowering blood pressure.

But guess what? They are popular foods available to everyone - cocoa, green tea, black tea, apples, grapes, and berries.

There is strong evidence certain plant compounds (flavan-3-ols, also known as flavanols or catechins) in these foods have beneficial effects on cardiovascular health. These compounds can lower blood pressure and improve endothelial function (functioning of the blood vessels). Two to three cups of tea daily! One to two servings of dark chocolate daily! Instead of chips for a snack, have an apple.

By the way, rather than focusing on eating just certain foods, it's better to improve your entire diet by eating more fruits, vegetables, whole grains, legumes, seeds, and nuts. All these foods are linked to good health and are considered part of a heart-healthy diet.

From Medscape: From Apples to Cocoa: Everyday Foods Linked to CV Benefits

The term “healthy diet” is often used but frequently remains vague. This is why scientific research into specific food components with preventive potential is gaining importance. Current studies suggest that certain plant compounds found in everyday foods such as apples, cocoa, and tea may have beneficial effects on cardiovascular (CV) health. ...continue reading "Common Foods Linked to Improved Heart Function"
