Major study reveals why COVID vaccine can trigger heart issues, especially in one group

NEWYou can now listen to Fox News articles!

One of the most widely known risks linked to the COVID-19 vaccine is myocarditis, especially in young males — and now a new Stanford study has shed some light on why this rare effect can occur.

Myocarditis, which is inflammation of the heart, occurs in about one in 140,000 people who receive the first dose of the vaccine and one in 32,000 after the second dose, according to a Stanford press release. Among males 30 and younger, that rises to one in 16,750.

Symptoms of the condition include chest pain, shortness of breath, fever and palpitations, which can occur just one to three days after vaccination. Another marker is heightened levels of cardiac troponin, which indicates that the heart muscle has been damaged.

LOWER DEMENTIA RISK LINKED TO ROUTINE VACCINATION IN MAJOR NEW ANALYSIS

In most cases, people who experience myocarditis recover quickly and restore full heart function, according to study author Joseph Wu, MD, PhD, the director of the Stanford Cardiovascular Institute and a professor of medicine and radiology.

“It’s not a heart attack in the traditional sense,” Wu told Fox News Digital. “There’s no blockage of blood vessels as found in most common heart attacks. When symptoms are mild and the inflammation hasn’t caused structural damage to the heart, we just observe these patients to make sure they recover.”

In rare cases, however, severe heart inflammation can lead to hospitalizations, critical illness or death, Wu noted.

Finding the cause

The new Stanford study — conducted in collaboration with The Ohio State University — aimed to determine the reasons for the myocarditis. The research team analyzed blood samples from vaccinated people, some with myocarditis and some without.

They found that those with myocarditis had two proteins in their blood, CXCL10 and IFN-gamma, which are released by immune cells. Those proteins then activate more inflammation.

COVID VACCINE UNDER NEW SCRUTINY AFTER STUDIES REVEAL POSSIBLE HEALTH RISKS

“We think these two are the major drivers of myocarditis,” said Wu. “Your body needs these cytokines to ward off viruses. It’s essential to immune response, but can become toxic in large amounts.”

In mouse and heart tissue models, high levels of these proteins led to signs of heart irritation, similar to mild myocarditis.

Prevention mechanism

“One of the most striking findings was how much we could reduce heart damage in our models by specifically blocking these two cytokines, without shutting down the entire (desired) immune response to the vaccine,” Wu told Fox News Digital, noting that a targeted, “fine‑tuning” immune approach might be enough to protect the heart.

“This points to a possible future way to prevent or treat myocarditis in people who are at the highest risk, while keeping the benefits of vaccination,” he added.

The team also found that genistein, an estrogen-like natural compound found in soybeans, reduced inflammation in lab tests, but this has not yet been tested in humans.

The findings were published in the journal Science Translational Medicine.

“This is a very complex study,” Fox News senior medical analyst Dr. Marc Siegel told Fox News Digital. “Myocarditis is very rare, and the immune mechanism makes sense.”

“Myocarditis is worse with COVID — much more common, and generally much more severe.” 

Wu agreed, adding that COVID infection is about 10 times more likely to cause myocarditis compared to mRNA-based vaccines.

‘Crucial tool’

The researchers emphasized that COVID-19 vaccines have been “heavily scrutinized” for safety and have been shown to have an “excellent safety record.”

“mRNA vaccines remain a crucial tool against COVID‑19, and this research helps explain a rare side effect and suggests ways to make future vaccines even safer, rather than a reason to avoid vaccination,” Wu said.

“The overall benefits of COVID‑19 vaccination still clearly outweigh the small risk of myocarditis for nearly all groups.”

The study did have some limitations, primarily the fact that most of the data came from experimental systems (mice and human cells in the lab), which cannot fully capture how myocarditis develops and resolves in real patients, according to Wu.

“This points to a possible future way to prevent or treat myocarditis in people who are at the highest risk.”

“These findings do not change what people should do right now, because our work is still at the preclinical (mouse and human cells) stage,” he said. “Clinical studies will be needed to confirm whether targeted treatments are safe and effective.”

The researcher also added that myocarditis risk could rise with other types of vaccines.

“Other vaccines can cause myocarditis and inflammatory problems, but the symptoms tend to be more diffuse,” he said in the release. “Plus, mRNA-based COVID-19 vaccines’ risks have received intense public scrutiny and media coverage. If you get chest pains from a COVID vaccine, you go to the hospital to get checked out, and if the serum troponin is positive, then you get diagnosed with myocarditis. If you get achy muscles or joints from a flu vaccine, you just blow it off.”

Diabetes surge among Americans could be driven by ‘healthy’ breakfasts, doctor warns

Diabetes surge among Americans could be driven by ‘healthy’ breakfasts, doctor warns

NEWYou can now listen to Fox News articles!

Americans consume foods every day that are marketed as “healthy,” when they could be quietly destroying their health, one doctor warns.

Dr. Mark Hyman, physician and co-founder of Function Health in California, says that much of America’s daily diet is filled with unhealthy ingredients.

“The amount of refined starches and sugars that are everywhere is just staggering to me, given what we know about how harmful they are,” he shared in an interview with Fox News Digital. “I don’t think people really understand.”

Hyman, author of the new book “Food Fix Uncensored,” said he’s “astounded” by what people are eating, especially for breakfast.

“People just eat sugar for breakfast,” he said. “They have muffins, they have bagels, they have croissants, they have sugar-sweetened coffees and teas.”

In addition to the traditionally sweet options for breakfast, some cereal brands and breakfast staples have adopted new “protein-packed” menu items and products, following health trends that encourage eating more protein.

“Highly processed food is not food.”

“Now, we’re seeing this halo of protein in certain things,” Hyman said, mentioning that many protein smoothies are “full of sugar.”

The doctor also noted that some popular cereals are now marketed as having protein in them. “My joke is, if it has a health claim on the label, it’s definitely bad for you,” he said.

Instead of starting the day with a “quick fix” or processed food, Hyman suggests choosing whole sources of protein and fat for breakfast, adding that “if there’s a little carbohydrate in there, it’s fine.”

For his own breakfast, Hyman said he has a protein shake with whey protein, avocado and frozen berries. Eggs and avocados are also a great protein-and-fat combo option, he added.

“It’s not that complicated — people need to just think about their breakfast not being dessert,” he said. “No wonder we’re in this cycle of obesity and diabetes. One in three teenage kids now has type 2 diabetes or pre-diabetes. That’s just criminal.”

Instead of counting calories and being in a caloric deficit as a way to lose weight and stay healthy, Hyman instead suggests focusing on how certain foods make you feel and how they impact your health.

“When you look at the way in which different types of calories affect your biology, you can just choose what you’re eating, and then you don’t have to worry about how much,” he told Fox News Digital.

“For example, if you eat a diet that doesn’t cause your insulin to spike — which is low in starch and sugar, higher in protein and fat — you won’t develop those swings in blood sugar, you won’t develop the spikes in insulin, you won’t deposit hungry fat … You will break that cycle.”

People are more likely to “self-regulate when they eat real food” instead of processed foods, which “bypasses the normal mechanisms of satiety, fullness and brain chemistry,” according to Hyman.

“Ultraprocessed food and junk food or highly processed food is not food,” he said. “It doesn’t support the health and well-being of an organism. It doesn’t do that. It does the opposite.”

Scientists make startling discovery when examining prostate cancer tissue

Scientists make startling discovery when examining prostate cancer tissue

NEWYou can now listen to Fox News articles!

Small fragments of plastic were found in the tumors of most prostate cancer patients, according to a new study from NYU Langone Health. 

In past studies, microplastics have been found in almost every human organ and in bodily fluids, but their impact on human health still isn’t fully understood.

The researchers analyzed tissue samples from 10 patients with prostate cancer who underwent surgery to remove the entire organ. 

Using visuals of both benign samples and tumor samples, as well as specialized equipment, the scientists identified plastic particles in 90% of the tumor samples and 70% of benign tissue samples, according to the study press release.

The cancerous tissue contained on average more than double the amount of plastic as healthy prostate tissue samples, the study found. This equates to about 40 micrograms of plastic per gram of tissue compared to 16 micrograms.

Researchers avoided contaminating the samples with other plastics by substituting standard tools with those made of aluminum, cotton and other non-plastic material, the release noted.

The scientists say this is the first direct evidence linking microplastics to prostate cancer.

“By uncovering yet another potential health concern posed by plastic, our findings highlight the need for stricter regulatory measures to limit the public’s exposure to these substances, which are everywhere in the environment,” said senior study author Vittorio Albergamo, assistant professor in the department of pediatrics at NYU Grossman School of Medicine, in the release.

“What is most striking is not that microplastics were detected, but that they were found embedded within tumor tissue itself,” Dr. David Sidransky, oncologist and medical advisor at SpotitEarly, a startup that offers an at-home breath-based test to detect early-stage cancer, told Fox News Digital.

“While complete avoidance is unrealistic, people can take practical steps to reduce exposure.”

“We already know microplastics are present in water, air, blood and even placental tissue. Their detection in prostate tumors suggests systemic distribution and long-term bioaccumulation,” added Maryland-based Sidransky, who was not involved in the study.

Study limitations

Albergamo cautioned that a larger sample is needed to confirm the findings. Additionally, Sidransky noted that the presence of microplastics alone does not prove they cause cancer.

“Tumors can act as ‘biologic sinks,’ meaning they may accumulate circulating particles simply because of altered vasculature and permeability,” he said.

A key unanswered question, according to the doctor, is whether microplastics are biologically active in ways that “promote DNA damage, immune modulation or chronic inflammation within the prostate.”

About one in eight men in the U.S. will be diagnosed with prostate cancer at some point in their lifetime, according to the Centers for Disease Control and Prevention.

The most actionable step men can take is appropriate screening and early detection, according to doctors. (iStock)

For those concerned about microplastics, Sidransky offered some insights.

“I believe the appropriate response is curiosity, not panic, and a commitment to understand more,” he said.

“While complete avoidance is unrealistic, people can take practical steps to reduce exposure, such as minimizing heating food in plastic containers, reducing bottled water consumption when possible, and favoring glass or stainless steel alternatives.”

The most actionable step men can take, however, is getting appropriate screenings to help ensure early detection, according to the doctor. Screening discussions should be individualized based on age, family history and other risk factors.
