For Alzheimer’s patients, eating pomegranates could help alleviate symptoms, study says: ‘Promising results’
Are pomegranates the next brain food?
The link between diet and dementia has been well-documented, and now researchers at the University of Copenhagen and the U.S. National Institute on Aging have found that eating more pomegranates, strawberries and walnuts could help improve memory among Alzheimer’s patients.
Those foods contain a substance called urolithin A, a compound created by gut bacteria.
COMMON COOKING INGREDIENT COULD REDUCE DEMENTIA MORTALITY RISK, STUDY SUGGESTS
“Our study on mouse models with Alzheimer’s disease shows that urolithin A, which is a naturally occurring substance in pomegranates, can alleviate memory problems and other consequences of dementia,” said Vilhelm Bohr, affiliate professor at the Department of Cellular and Molecular Medicine at the University of Copenhagen, in a press release.

In patients with neurodegenerative diseases such as Alzheimer’s, the brain has trouble removing weak mitochondria, which builds up and impairs brain function.
Utolithin A has been shown to remove weak mitochondria from the brain, thus restoring cognitive function, the researchers found.
The study findings were published in the journal Alzheimer’s and Dementia.

Researchers aren’t sure how much of the substance is needed to achieve positive results.
“We still cannot say anything conclusive about the dosage, but I imagine that it is more than a pomegranate a day,” Bohr said.
“However, the substance is already available in pill form, and we are currently trying to find the right dosage.”

Utolithin A could ideally be used as a safe way to prevent neurological diseases, he noted.
“The advantage of working with a natural substance is the reduced risk of side effects,” he said.
“Clinical trials with Urolithin A have been effective in muscular disease, and now we need to look at Alzheimer’s disease.”

Based on the “promising results” seen in the mouse models, the researchers are planning to conduct clinical trials on humans.
Tanya Freirich, a registered dietitian nutritionist in Charlotte, North Carolina, was not involved in the study but shared comments on the findings.
“Long-term urolithin A treatment significantly improved learning, memory and olfactory function (smelling) in mice,” she told Fox News Digital.
“The advantage of working with a natural substance is the reduced risk of side effects.”
“As a dietitian, I always recommend that people discuss any supplement with their personal medical care provider before starting it.”
As the research is still very new and has only been done in mice so far, Freirich noted that the results “cannot be extrapolated to humans with certainty.”
She added, “I would certainly recommend to anyone that adding pomegranates, strawberries and walnuts to the diet is a great idea.”

“These are whole, unprocessed and very nutritious foods, high in antioxidants and, in the case of walnuts, omega 3s.”
These foods are unlikely to cause any harm if consumed in typical portion sizes, Freirich noted, unless there is an allergy or another specific reason to avoid them.
Other recommended foods for brain health include adequate dietary intake of omega 3s (salmon, walnuts, chia seeds, ground flaxseed, olive oil), green leafy vegetables, berries, and legumes (beans, lentils, chickpeas), according to Freirich.
FASTING COULD REDUCE SIGNS OF ALZHEIMER’S DISEASE, STUDIES SUGGEST: ‘PROFOUND EFFECTS’
Maintaining at least 150 minutes of physical activity per week and keeping the brain sharp with activities and community engagement can also help mitigate Alzheimer’s symptoms, the nutritionist added.

Erin Palinski-Wade, a New Jersey-based dietitian and author of the book “Belly Fat Diet For Dummies,” who was also not involved in the study, said the “promising” results support other research that has found an association between pomegranates and improved cognition and memory.
“More research needs to be done to identify how much pomegranate would be needed to achieve cognitive benefits, but adding even small amounts of pomegranate to the diet can be beneficial to overall health,” a nutritionist told Fox News Digital. (iStock)

‘Fire-breathing’ trend linked to severe burns in teens, officials warn
NEWYou can now listen to Fox News articles!
Parents are being warned of a new trend among kids, involving alcohol and an open flame.
The “fire-breathing” challenge has led to reports of severe burns, according to local news outlets.
Kids and teens are reportedly holding alcohol in their mouths and blowing it onto a match or another open flame to mimic “breathing fire.”

Pitcairn Fire Chief Tommy Dick told CBS News Pittsburgh (KDKA) the 14-year-old girl was playing with isopropyl alcohol at an apartment complex.
“It’s not a very smart thing for anybody to do, let alone children,” Dick said. “It’s supposed to be for cleaning off wounds and cuts and stuff, not ingesting and trying to blow fire.
A local fire chief told CBS News Pittsburgh that the incident could have been fatal for the teen. (iStock)
“This could have easily gone inside their digestive tract, and she could have died.”
Anyone who has ingested isopropyl alcohol requires immediate medical attention, according to Healthline, because it can cause stomach pain, dizziness, confusion and slowed breathing. In severe cases, it can lead to a coma.

Ancient herb known as ‘nature’s Valium’ touted for improving sleep and anxiety
NEWYou can now listen to Fox News articles!
Valerian, an herbal supplement long used for sleep and relaxation, has been referred to as “nature’s Valium” — but experts are divided on whether it truly compares to the prescription sedative.
The herb, which is sold as a dietary supplement in the U.S., is a common ingredient in products marketed as “mild sedatives” and sleep aids, according to the National Institutes of Health.
Valium, the brand name for diazepam, is used to treat anxiety, seizures and muscle spasms by calming the nervous system, Cleveland Clinic notes.
Valerian supplements are derived from the roots of Valeriana officinalis, a flowering plant native to Europe and Asia that has also naturalized in northeastern America, according to the American Botanical Council (ABC).
The plant has a “long history of medicinal use,” per the ABC, with the primary goal of reducing anxiety and stress as well as improving sleep quality. It has historically also been used for migraines, fatigue and stomach cramps.

Dried valerian roots can be prepared as teas or tinctures, while other plant materials and extracts have been distributed as capsules or tablets, per the NIH.
The agency noted, however, that there is a “relatively small amount of research” investigating the herb’s impact on various conditions.
POPULAR SLEEP POSITIONS COULD BE DAMAGING YOUR NERVES, ACCORDING TO EXPERTS
However, Stefan Gafner, Ph.D., chief science officer of the American Botanical Council in Texas, confirmed that some clinical trials have explored valerian root’s effects.
A 2020 medical review published in the Journal of Evidence-Based Integrative Medicine found that both powdered root and root extracts show a “clear” benefit in treating anxiety, Gafner told Fox News Digital.

While valerian may have some benefits, Gafner said he doesn’t think it “makes sense” to compare it to diazepam (Valium).
“I can understand that both are used to relieve anxiety, but valerian is a much milder ingredient, and is really used for mild cases of anxiety and sleep issues,” he told Fox News Digital.
Some valerian users have reported improved sleep and reduced anxiety, according to recent research. (iStock)
Unlike valerian, diazepam carries a risk of dependence and is generally prescribed short-term, the expert said, and the spectrum of potential adverse effects is “very different.”
MISSING SLEEP MAY TAKE A HIDDEN TOLL ON YOUR BRAIN AND LONGEVITY, RESEARCH REVEALS
Gafner said he “absolutely” recommends the use of valerian root to relieve anxiety and stress and to improve sleep.
“I have used it myself and I believe it’s an ingredient with well-documented benefits, especially for people with problems falling asleep,” he said. “It is well-tolerated and very safe… although some sources caution [against] driving a car or using heavy machinery when using valerian.”

Dr. Joseph Mercola, a board-certified family medicine osteopathic physician and author of the new book “Weight Loss Cure,” said valerian’s comparisons to Valium may “exaggerate what the science actually shows.”

“Valerian root contains compounds that appear to enhance calming brain chemicals, particularly the neurotransmitter GABA, which helps quiet nerve activity and supports relaxation,” the Florida-based expert told Fox News Digital.
“Some studies do report modest improvements in sleep quality or shorter time to fall asleep, while others find no meaningful difference compared with placebo.”
Valerian supplementation may not be right for everyone seeking better sleep, one doctor said. (iStock)
Side effects may include headaches, dizziness, digestive upset or next-day grogginess, Mercola noted, adding that he would not recommend it as a primary strategy for anxiety, stress or sleep.
“Because long-term safety studies remain limited, and supplement quality varies widely, you should approach valerian with caution rather than view it as a universal sleep solution,” he advised.
“You should approach valerian with caution rather than view it as a universal sleep solution.”
“I encourage people to focus first on strategies that correct the underlying drivers of poor sleep,” Mercola advised. “When you fix those foundations, you often find that you no longer need an herbal sedative at all.”

“Bright sunlight during the day helps regulate your circadian rhythm and signals your brain to produce melatonin later at night,” he said. “At the same time, complete darkness [at night] supports the hormonal signals that allow deep, restorative sleep.”
Certain nutrients can also promote relaxation and sleep quality, including magnesium, which helps to regulate the nervous system, according to the doctor.

GABA may help to calm nerve activity, reduce stress markers and improve perceived sleep quality, Mercola said, while glycine — taken at about 3 grams an hour before bed — may support relaxation, promote the body’s nighttime temperature drop, and improve sleep onset and overall quality.

“When you combine sunlight exposure, magnesium, GABA and glycine, you support the biological systems that control sleep instead of relying on a sedating herb with mixed evidence,” the doctor concluded.

GLP-1 drugs linked to higher fracture risk, osteoporosis and gout, new studies suggest
NEWYou can now listen to Fox News articles!
GLP-1 medications such as Ozempic and Wegovy have transformed treatment for Type 2 diabetes and obesity, but new research suggests doctors may need to pay closer attention to bone health, especially in older patients taking the drugs.
Older adults with Type 2 diabetes who started GLP-1s had an 11% higher risk of fragility fractures compared to those taking other diabetes medications, a study published in February in the Journal of Clinical Endocrinology & Metabolism found.
Dr. Michal Kasher Meron, an endocrinologist at Meir Medical Center in Israel and lead author of the study, said the relative increase may sound small, but it carries weight for an at-risk population.
“Both older age and Type 2 diabetes are independent risk factors for fragility fractures,” Kasher Meron told Fox News Digital. “This is a population that deserves special attention.”
A new study suggests older adults with Type 2 diabetes taking GLP-1 medications may face increased fracture risk. (iStock)
Fragility fractures are breaks from minor falls or routine activity, often linked to osteoporosis, and can lead to hospitalization, loss of independence and even increased mortality in older adults, Kasher Meron noted.
The study followed more than 46,000 adults 65 and older for nearly three years. After adjustments, GLP-1 users had a modest but statistically significant increase in fracture risk.
NEW WEGOVY PILL OFFERS NEEDLE-FREE WEIGHT LOSS — BUT MAY NOT WORK FOR EVERYONE
Previous research in younger patients using older GLP-1s did not show increased fracture risk, but newer, more potent versions are now widely prescribed to older adults, Kasher Meron noted.
“In older adults treated with contemporary medications, the fracture risk picture looks different and warrants close attention,” she said.
Separate research found slightly higher rates of osteoporosis and gout among adults using GLP-1s. (iStock)
The study, however, was observational, meaning it shows an association but not causation. Researchers were unable to determine whether the risk was driven by weight loss, changes in diet, muscle loss or a direct effect on bone.

Nonetheless, Kasher Meron says, “Bone health should be assessed before starting these medications in older patients — not as an afterthought.”
The findings come as separate research presented at the American Academy of Orthopaedic Surgeons’ annual meeting this month raised additional bone health concerns.
In an analysis of more than 146,000 adults with obesity and Type 2 diabetes, GLP-1 users were found to have a 29% higher relative risk of osteoporosis over five years compared to nonusers, according to reports.

Rates of gout were also slightly higher, affecting 7.4% of GLP-1 users compared to 6.6% of nonusers — about a 12% relative increase.

Osteomalacia, a softening of the bones, was rare but occurred about twice as often in GLP-1 users, according to the study, which has not yet been peer reviewed. It was also observational, showing only an association. Fox News Digital has reached out to the researcher for comment.
Several mechanisms could be at play, experts say. GLP-1 medications suppress appetite and can lead to rapid weight loss. Significant weight loss is known to reduce bone density, partly because less mechanical load is placed on the skeleton.
“It’s the same idea as when we always hear about astronauts going up into space, and they’re in a gravity-zero environment for too long,” lead author Dr. John Horneff, an associate professor of orthopedic surgery at the University of Pennsylvania, told NBC News.
“There’s nothing forcing their bones to kind of hold their weight anymore. And a lot of those astronauts come back with low bone density.”
Additionally, eating fewer calories may also mean lower intake of calcium, vitamin D and protein, nutrients critical for bone strength.

Rapid weight loss can also temporarily increase uric acid levels, a byproduct of tissue breakdown, which may explain the uptick in gout cases.

Despite the findings, experts say the results should not discourage appropriate use of GLP-1 medications, which have proven benefits for blood sugar control, weight loss and cardiovascular risk reduction.
In addition to bone density screening, experts say patients should ensure adequate nutrition and resistance training to help preserve muscle and bone during weight loss.

The known risks and benefits of the drugs are reflected in the current FDA-approved labeling, Liz Skrbkova, head of U.S. media relations for Novo Nordisk, told Fox News Digital. She emphasized that semaglutide has demonstrated cardiovascular, kidney and liver benefits when used under medical supervision.
