Experts Doubt Kennedy’s Timetable for Finding the Cause of Autism
Robert F. Kennedy Jr., the nation’s health secretary, pledged on Thursday to seek out experts globally to discover the reasons for the increasing rates of autism in the United States.
“We’ve launched a massive testing and research effort that’s going to involve hundreds of scientists from around the world,” Mr. Kennedy announced at a cabinet meeting held by President Trump. “By September, we will know what has caused the autism epidemic and we’ll be able to eliminate those exposures.”
“There will be no bigger news conference than that,” Mr. Trump replied.
But scientists who have worked for decades to find a cause greeted Mr. Kennedy’s predicted timeline with skepticism.
They said that a single answer would be hard to identify in a field of possible contributors including pesticides, air pollution and maternal diabetes.
Dr. Philip Landrigan, a pediatrician and expert on environmental toxins, pointed to the current mass layoffs and cutbacks for research at Mr. Kennedy’s Department of Health and Human Services as one reason for doubting such quick progress.
“Given that a great deal of research on autism and other pediatric diseases in hospitals and medical schools is currently coming to a halt because of federal funding cuts from H.H.S.,” he said, “it is very difficult for me to imagine what profound scientific breakthrough could be achieved between now and September.”
Mr. Kennedy’s office did not offer many details on the plan. Later on Thursday, Mr. Kennedy revealed a few more clues, saying that the National Institutes of Health would lead the effort.
He said the Centers for Disease Control and Prevention would soon release data showing that the autism diagnoses had now increased to one of every 31 children. Many scientists and doctors attributed the rise in autism rates over the last several decades in part to growing awareness of the disorder and to expanded diagnoses along a spectrum.
“We are launching requests to scientists from all over the country and all over the world,” Mr. Kennedy said in an interview on Fox News. “Everything is on the table: our food system, our water, our air, different ways of parenting, all the kind of changes that may have triggered this epidemic.”
In the interview, Mr. Kennedy also said an important part of the effort would be to compare autism rates in vaccinated and unvaccinated children. It’s an angle that many scientists dismiss, saying that parents who vaccinate their children are also more likely to get a diagnosis, given higher rates of interaction with health providers.
Many scientists who have observed Mr. Kennedy’s dogged opposition to many vaccines over two decades — and his frequent attempts to tie autism to vaccines — have dismissed his claims, citing the scientific consensus that debunked any such link. Scrutiny of his pledges to begin “gold standard” research only heightened in recent weeks when David Geier, a largely discredited researcher, was hired at H.H.S. to study any potential link between vaccines and autism.
Irva Hertz-Picciotto, director of environmental epidemiology of neurodevelopment at the University of California at Davis MIND Institute, said she had been seeking a cause for autism for 20 years.
It’s an exciting time for the field, she said, with multiple studies beginning to point to factors that could play a role. Among the possible links are pesticide exposure through food or nearby agricultural fields; workplace exposures to solvents; fevers or infections during pregnancy; maternal diabetes; and exposure to chemicals in plastics called phthalates or to PFAS, known as “forever chemicals” for their tendency to persist in the environment.
Some studies have found that the effect of environmental exposures can vary based on a person’s genes, “emphasizing the complexity of this syndrome.” Dr. Hertz-Picciotto said it was challenging to get funding for clinical studies that could shed light on a cause of autism, but new research could help advance the field. Those studies, though, could take years.
That all of the research could be sorted out by September, she said, was “ludicrous.”
Dr. Alice Kuo, the chief of pediatric medicine who cares for children and adults with autism at the University of California, Los Angeles, said she was involved in a yearslong project by the National Institutes of Health called the National Children’s Study. It followed thousands of children and parents and elicited information, including the possible causes of autism. The study was costly and ended far earlier than planned, Dr. Kuo said.
She said an effort to do something as rigorous would take months to plan and design — and years to arrive at an answer.
In a social media post on Thursday, Mr. Kennedy recognized the assistance of the president and the Make America Healthy Again Commission — a subgroup of the cabinet that includes Linda McMahon, the education secretary, and Russell Vought, director of the Office of Management and Budget. Like Mr. Kennedy, they are not doctors or scientists.
“Thanks to your MAHA Commission, we’ll soon identify the root causes of the autism epidemic,” Mr. Kennedy wrote in a social media post.
Created by an executive order in February, the commission is charged with assessing in 100 days the threat to children of food ingredients, chemicals, medications and other exposures. Within 180 days, the commission is expected to submit a strategy to the president to address its findings.

ChatGPT could miss your serious medical emergency, new study suggests
NEWYou can now listen to Fox News articles!
This story discusses suicide. If you or someone you know is having thoughts of suicide, please contact the Suicide & Crisis Lifeline at 988 or 1-800-273-TALK (8255).
Artificial intelligence has been touted as a boon to healthcare, but a new study has revealed its potential shortcomings when it comes to giving medical advice.
In January, OpenAI launched ChatGPT Health, the medical-focused version of the popular chatbot tool.
The company introduced the tool as “a dedicated experience that securely brings your health information and ChatGPT’s intelligence together, to help you feel more informed, prepared and confident navigating your health.”
But researchers at the Icahn School of Medicine at Mount Sinai have found that the tool failed to recommend emergency care for a “significant number” of serious medical cases.
The study, published in the journal Nature Medicine on Feb. 23, aimed to explore how ChatGPT Health — which is reported to have about 40 million users daily — handles situations where people are asking whether to seek emergency care.

“Right now, no independent body evaluates these products before they reach the public,” lead author Ashwin Ramaswamy, M.D., instructor of urology at the Icahn School of Medicine at Mount Sinai in New York City, told Fox News Digital.
“We wouldn’t accept that for a medication or a medical device, and we shouldn’t accept it for a product that tens of millions of people are using to make health decisions.”
Emergency scenarios
The team created 60 clinical scenarios across 21 medical specialties, ranging from minor conditions to true medical emergencies.
Three independent physicians then assigned an appropriate level of urgency for each case, based on published clinical practice guidelines in 56 medical societies.

The researchers conducted 960 interactions with ChatGPT Health to see how the tool responded, taking into account gender, race, barriers to care and “social dynamics.”
While “clear-cut emergencies” — such as stroke or severe allergy — were generally handled well, the researchers found that the tool “under-triaged” many urgent medical issues.

For example, in one asthma scenario, the system acknowledged that the patient was showing early signs of respiratory failure — but still recommended waiting instead of seeking emergency care.
“ChatGPT Health performs well in medium-severity cases, but fails at both ends of the spectrum — the cases where getting it right matters most,” Ramaswamy told Fox News Digital. “It under-triaged over half of genuine emergencies and over-triaged roughly two-thirds of mild cases that clinical guidelines say should be managed at home.”
PARENTS FILE LAWSUIT ALLEGING CHATGPT HELPED THEIR TEENAGE SON PLAN SUICIDE
Under-triage can be life-threatening, the doctor noted, while over-triage can overwhelm emergency departments and delay care for those in real need.
Researchers also identified inconsistencies in suicide risk alerts. In some cases, it directed users to the 988 Suicide and Crisis Lifeline in lower-risk scenarios, and in others, it failed to offer that recommendation even when a person discussed suicidal ideations.
“ChatGPT Health performs well in medium-severity cases, but fails at both ends of the spectrum.”
“The suicide guardrail failure was the most alarming,” study co-author Girish N. Nadkarni, M.D., chief AI officer of the Mount Sinai Health System, told Fox News Digital.
ChatGPT Health is designed to show a crisis intervention banner when someone describes thoughts of self-harm, the researcher noted.

“We tested it with a 27-year-old patient who said he’d been thinking about taking a lot of pills,” Nadkarni said. “When he described his symptoms alone, the banner appeared 100% of the time. Then we added normal lab results — same patient, same words, same severity — and the banner vanished.”
“A safety feature that works perfectly in one context and completely fails in a nearly identical context … is a fundamental safety problem.”
CHATGPT HEALTH PROMISES PRIVACY FOR HEALTH CONVERSATIONS
The researchers were also surprised by the social influence aspect.
“When a family member in the scenario said ‘it’s nothing serious’ — which happens all the time in real life — the system became nearly 12 times more likely to downplay the patient’s symptoms,” Nadkarni said. “Everyone has a spouse or parent who tells them they’re overreacting. The AI shouldn’t be agreeing with them during a potential emergency.”
Fox News Digital reached out to Open AI, creator of ChatGPT, requesting comment.
Physicians react
Dr. Marc Siegel, Fox News senior medical analyst, called the new study “important.”
“It underlines the principle that while large language models can triage clear-cut emergencies, they have much more trouble with nuanced situations,” Siegel, who was not involved in the study, told Fox News Digital.
ChatGPT and other LLMs can be helpful tools, a doctor said, but they “should not be used to give medical direction.” (iStock)
“This is where doctors and clinical judgment come in — knowing the nuances of a patient’s history and how they report symptoms and their approach to health.”
ChatGPT and other LLMs can be helpful tools, Siegel said, but they “should not be used to give medical direction.”
“Machine learning and continued input of data can help, but will never compensate for the essential problem – human judgment is needed to decide whether something is a true emergency or not.”
BREAKTHROUGH BLOOD TEST COULD SPOT DOZENS OF CANCERS BEFORE SYMPTOMS APPEAR
Dr. Harvey Castro, an emergency physician and AI expert in Texas, echoed the importance of the study, calling it “exactly the kind of independent safety evaluation we need.”
“Innovation moves fast. Oversight has to move just as fast,” Castro, who also did not work on the study, told Fox News Digital. “In healthcare, the most dangerous mistakes happen at the extremes, when something looks mild but is actually catastrophic. That’s where clinical judgment matters most, and where AI must be stress-tested.”
Study limitations
The researchers acknowledged some potential limitations in the study design.
“We used physician-written clinical scenarios rather than real patient conversations, and we tested at a single point in time — these systems update frequently, so performance may change,” Ramaswamy told Fox News Digital.

Additionally, most of the missed emergencies happened in situations where the danger depended on how the condition was changing over time. It’s not clear whether the same problem would happen with acute medical emergencies.
Because the system had to choose just one fixed urgency category, the test may not reflect the more nuanced advice it might give in a back-and-forth conversation, the researchers noted.

Also, the study wasn’t large enough to confidently detect small differences in how recommendations might vary by race or gender.
“We need continuous auditing, not one-time studies,” Castro noted. “These systems update frequently, so evaluation must be ongoing.”
‘Don’t wait’
The researchers emphasized the importance of seeking immediate care for serious issues.

“If something feels seriously wrong — chest pain, difficulty breathing, a severe allergic reaction, thoughts of self-harm — go to the emergency department or call 988,” Ramaswamy advised. “Don’t wait for an AI to tell you it’s OK.”
The researchers noted that they support the use of AI to improve healthcare access, and that they didn’t conduct the study to “tear down the technology.”

“These tools can be genuinely useful for the right things — understanding a diagnosis you’ve already received, looking up what your medications do and their side effects, or getting answers to questions that didn’t get fully addressed in a short doctor’s visit,” Ramaswamy said.
“That’s a very different use case from deciding whether you need emergency care. Treat them as a complement to your doctor, not a replacement.”
“This study doesn’t mean we abandon AI in healthcare.”
Castro agreed that the benefits of AI health tools should be weighed against the risks.
“AI health tools can increase access, reduce unnecessary visits and empower patients with information,” he said. “They are not inherently unsafe, but they are not yet substitutes for clinical judgment.”

“This study doesn’t mean we abandon AI in healthcare,” he went on. “It means we mature it. Independent testing and stronger guardrails will determine whether AI becomes a safety net or a liability.”

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.
In addition to the traditionally sweet options for breakfast, some cereal brands and breakfast staples have adopted new “protein-packed” menu items and products. (iStock)
“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
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.
NIGHTLY BATHROOM HABIT WAS MISSED SIGN OF COMMON MEN’S CANCER: ‘I DIDN’T KNOW’
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.

The study findings were presented during the American Society of Clinical Oncology’s Genitourinary Cancers Symposium in San Francisco on Feb. 26.

“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.
