A New Jersey man’s death is the first known to be linked to a tick-borne meat allergy, according to researchers at UVAHealth in Virginia.
The unidentified man, 47, reportedly died last summer, four hours after eating a hamburger and just two weeks after a similar episode triggered by steak.
With the summer episode, the man experienced severe abdominal pain, diarrhea and vomiting after eating the steak, a UVAHealth press release said.

The incident was initially reported as “sudden unexplained death” until Dr. Thomas Platts-Mills of UVA Health determined the man suffered a fatal allergic reaction.
The findings were published in The Journal of Allergy and Clinical Immunology: In Practice.

The allergy, alpha-gal syndrome (AGS) — also known as “red-meat allergy” or the “tick bite meat allergy” — is caused by the bite of the Lone Star tick, which is found primarily in Southeastern and Eastern states, according to the Centers for Disease Control and Prevention.
The tick’s saliva contains a sugar molecule called alpha-gal, which is injected into the body with the bite. This triggers allergies to certain types of red meat (primarily pork, beef, rabbit, lamb or venison) or products made from mammals (including cheese, milk, other dairy products and gelatin).

When people eat any foods containing the allergens, they can experience serious allergy symptoms within a few hours, although some may only have mild reactions.
Symptoms may include rash, nausea and vomiting after eating beef, pork or lamb, according to researchers. Some may also experience itchy or scaly skin; swelling of the lips, face, tongue and throat; and wheezing or shortness of breath, according to Mayo Clinic.

Although fatal anaphylaxis has been noted as a rare risk in severe cases, the New Jersey man’s death was the first to be attributed to the allergy.
Other factors that may have contributed to his severe reaction, according to Platts-Mills, include a beer he drank with his burger, his exposure to ragweed pollen and recent exercise.

“The important information for the public is: First, that severe abdominal pain occurring three to five hours after eating beef, pork or lamb should be investigated as a possible episode of anaphylaxis; and, second, that tick bites that itch for more than a week or larvae of ticks often called ‘chiggers’ can induce or increase sensitization to mammalian-derived meat,” Platts-Mills, former chief of UVA Health’s Division of Asthma, Allergy and Clinical Immunology, said in the release.
“On the other hand, most individuals who have mild to moderate episodes of hives can control symptoms with an appropriate diet.”

A diagnosis of AGS requires antibody testing and a clinical exam. Many patients face a long road to diagnosis — an average of seven years, according to Dr. Johanna Salzer, CDC epidemiologist and author of a 2023 report on AGS.

“And to get diagnosed, they have to have access to an allergist,” Salzer previously told Fox News Digital. “For many people, there are barriers to get that level of treatment.”

“However, for some people, if they remove the foods from their diet that can reactivate alpha-gal syndrome, over time, their antibody levels may drop,” the expert said.
There is no treatment or cure for AGS, though physicians can help patients manage their symptoms.

“There are a number of things [that] healthcare providers can provide to alleviate symptoms depending on the patients’ individual reactions,” Salzer said.
“Those with more severe reactions are administered EpiPens in case they go into anaphylactic shock.”
Prevention tips
To protect against tick bites, Salzer recommends applying EPA-approved insect repellent, those containing DEET, picaridin, IR3535, Oil of Lemon Eucalyptus (OLE), para-menthane-diol (PMD) or 2-undecanone, whenever going into an area where tick bites are a possibility.

Wearing long-sleeved shirts, long pants and socks and avoiding grassy, brushy and wooded areas can also help to prevent bites.
“When returning from an area that is known to have ticks, be sure to shower and do a very thorough check,” Salzer advised.

Platts-Mills urged doctors and patients who live in areas where Lone Star ticks are common to be aware of the risk.
“More specifically, if they have unexpected episodes of severe abdominal pain occurring several hours after eating mammalian meat, they should be investigated for possible sensitization to the oligosaccharide alpha-gal,” he added.

Common food preservatives may contribute to higher risks of high blood pressure and cardiovascular disease, according to a large French study.
Researchers analyzed data from 112,395 adults averaging 42 years of age, assessing their detailed dietary intake with an average follow-up of nearly eight years.
Among the participants, 5,544 developed hypertension during the follow-up period, and 2,450 experienced cardiovascular disease events.
‘ADDICTIVE’ ULTRA-PROCESSED FOODS LINKED TO SPIKE IN CHRONIC DISEASE, RESEARCHERS WARN
Higher consumption of total non-antioxidant preservatives was associated with a 29% greater risk of hypertension and a 16% higher risk of cardiovascular disease.
Higher consumption of total antioxidant preservatives was linked to a 22% spike in hypertension risk.

Out of the 17 preservative additives consumed by at least 10% of participants, eight in particular were associated with higher rates of hypertension, including the following.
- Potassium sorbate
- Sorbic acid
- Sodium nitrite
- Potassium nitrite
- Sodium metabisulphite
- Potassium metabisulphite
- Citric acid
- Tripotassium citrate

Only one of the preservatives – ascorbic acid, which is the food additive form of vitamin C – was significantly associated with higher cardiovascular disease risk.
The finding does not mean that dietary vitamin C itself causes cardiovascular disease, the researchers noted. The study examined ascorbic acid in the form used as a food additive in processed foods, not vitamin C from fruits, vegetables or supplements.

The findings were published in the European Heart Journal.
“This is a very important study that puts together what we already know – that preservatives of all kinds raise blood pressure and contribute directly to heart disease and stroke over eight years,” Dr. Marc Siegel, Fox News senior medical analyst, told Fox News Digital.

“Whereas potassium itself can lower blood pressure, the additive potassium sorbate has previously been found to be associated with hypertension in a large study in the European Heart Journal,” the doctor, who was not involved in the study, told Fox News Digital. “Potassium metabisulphite was also found to raise pressure in the same study.”
The same was found for sodium nitrite in the new study, Siegel noted, with 73% of participants consuming it regularly – “mostly in processed foods like hot dogs, ham, bacon and deli meats.”
“Preservatives of all kinds raise blood pressure and contribute directly to heart disease and stroke over eight years,” a doctor told Fox News Digital. (iStock)
“This has been found in previous research for many years,” he added.
Siegel also discussed the 22% increased risk linked to ascorbic acid. “I am dubious about this association, as it has not generally been found before, but perhaps the risk is when it is used as a chemical preservative.”

“For all the sodium additives, this is expected, but surprising with extracts of rosemary and citric acid – the key to both of these ingredients is when they are used as preservatives (chemicals),” he added.
Potential limitations
As this was an observational study, it could not prove that the additives caused the health conditions.
Also, the participants who volunteered for the study were generally healthier, more educated and more often female than the general French population, the researchers noted.

There was also the chance that hypertension was underdiagnosed in some participants.

While the researchers estimated people’s dietary intake as accurately as possible, there was a chance that some consumption was inaccurately reported.
The authors emphasized that these findings need to be confirmed in further research of other populations.

If the results are replicated in future research, some food preservatives may face additional safety reviews focused on their effects on the cardiovascular system, the researchers suggested.
“The take-home is to use natural ingredients as much as possible, and especially beware of sodium chemical preservatives when it comes to risk of heart disease and stroke from associated hypertension,” Siegel concluded.
JD Vance reveals his favorite dad joke
Dana Perino, Greg Gutfeld, Jesse Watters, and Jessica Tarlov engage in a lighthearted exchange of classic dad jokes on Fox News’ ‘The Five’. The discussion is sparked by recent research highlighted in The Washington Post, which indicates that humor, even ‘cringeworthy’ dad jokes, plays a surprisingly important role in parenting and can help strengthen the bond between fathers and children. The panel illustrates this point with their own memorable one-liners.

“My neighbor tiled my roof for free. He said it was on the house.”
While that dad joke might elicit a heavy sigh from family members, experts say a silly pun can alter internal body chemistry and lower stress, potentially providing real health benefits.
Dad jokes are uniquely distinguished by their structure, content and comedic devices, according to a study published on PsyArXiv, an open-access preprint repository for psychology research.
TRENDY ‘CORTISOL COCKTAIL’ COULD MELT STRESS AND POUNDS AWAY, INFLUENCERS CLAIM
In analyzing thousands of examples, psychologists Paul J. Silvia (University of North Carolina at Greensboro) and Meriel I. Burnett (University of Massachusetts Amherst) found that dad humor is firmly rooted in puns and wordplay.
While more advanced comedy requires context, a joke about a neighbor’s roof may only require someone to understand the dual meaning of a single phrase.

This predictable structure makes dad jokes broadly accessible, creating opportunities for shared humor across generations, the researchers said.
Laughter alters internal chemistry by decreasing stress hormones like cortisol and epinephrine, while simultaneously increasing happiness chemicals like dopamine, serotonin and endorphins.

“When we see children laugh, we witness the brilliance of the brain in action: learning, connecting and growing,” Jacqueline Harding, PhD, an early childhood expert at Middlesex University in London, told Fox News Digital.
In her book, “The Brain That Loves to Laugh,” Harding states that joy is a complex biological phenomenon that helps children navigate stress and build more resilient, receptive minds.

“Hope and humor, it seems, are not just the seasoning of life, but foundational to a recipe for healthy development.”
The physical benefit extends directly to the family unit. Sharing a good laugh can boost oxytocin, a hormone known to deepen emotional bonds between parents and children. It also promotes what psychologists call co-regulation, experts say.

“Spontaneous, joyful play is an antidote to stress, as it increases levels of endorphins released by the brain,” Harding said.
