Fact-Checking RFK Jr.’s Health Claims on Obesity, Medicaid and Fluoride
During the hearing to consider his nomination to lead the Department of Health and Human Services, Robert F. Kennedy Jr. spoke at length about issues in health and medicine, including the cause of chronic illnesses, Covid-19 and ultraprocessed foods.
Here is a running list of key health claims, fact-checked by our reporters.
Chronic Disease
Mr. Kennedy’s opening statement focused on rising chronic health conditions, saying there was a crisis in children’s health in the United States. Many experts agree — though they disagree about the causes.
Forty percent of children have a chronic health condition, and the figure is higher for adolescents when obesity is included.
Roughly one in 36 children is diagnosed with an autism spectrum disorder, according to data from the Centers for Disease Control and Prevention. One in four has an allergy or eczema, and rates of Type 2 diabetes have been rising in those 19 and under every year.
And while Type 2 diabetes rates are rising, they are still low: According to the American Diabetes Association, it occurs in 0.35 percent of Americans under the age of 20.
Who Covid-19 Affects
Senator Michael Bennet of Colorado pressed Mr. Kennedy on a statement Mr. Kennedy made in 2023 in which he suggested that the coronavirus targeted and spared certain ethnic groups.
“Covid-19 is targeted to attack Caucasians and Black people,” he said in a video from The New York Post. “The people who are most immune are Ashkenazi Jews and Chinese.”
In response to Mr. Bennet, Mr. Kennedy referred to a federally funded study from the Cleveland Clinic published early in the pandemic that tried to decipher who was most susceptible to the virus.
Scientists have said that Mr. Kennedy’s interpretation of the study widely distorted the findings in the paper. While it found genetic differences that might make one individual more susceptible to Covid than another, the differences were too rare to make any generalizations about large groups of people.
Children’s Risk From Covid
During the hearing, Mr. Kennedy also asserted that 6-year-old children “basically” have “zero” risk from Covid.
The C.D.C. has noted that children with underlying medical conditions are at higher risk from severe outcomes from Covid, as well as infants younger than six months of age.
Ultraprocessed Foods and Obesity
Early in the hearing, Mr. Kennedy singled out processed food as a driver of the obesity epidemic.
“We shouldn’t be giving 60 percent of the kids in school processed food that is making them sick,” he said.
Many public health and nutrition experts say that ultraprocessed foods — which make up an estimated 73 percent of the U.S. food supply — are probably a factor in the obesity crisis in the United States, and it would be beneficial to cut back on them.
But other researchers say that the obesity epidemic is likely a result of many entangled factors, both environmental and genetic, and that the phenomenon may have started long before there were ultraprocessed foods.
The category is also wide-ranging, and it’s not clear if all ultraprocessed foods are harmful, experts say. There may be downsides to avoiding some ultraprocessed foods, like flavored yogurts and whole wheat breads and cereals, they add, because they can provide valuable nutrients.
Lindsey Smith Taillie, an associate professor of nutrition at the U.N.C. Gillings School of Global Public Health, said that it would be “transformative” to remove ultraprocessed foods from school lunches. But, she added, schools would need more resources to prepare meals from scratch.
Medicare and Medicaid
Throughout the hearing, Mr. Kennedy struggled with the nuances of Medicaid and Medicare.
He suggested “more people would rather be on Medicare Advantage” but can’t afford it because it’s more expensive. In fact, Medicare Advantage is generally less expensive on a monthly basis for beneficiaries.
He also described Medicaid as being fully federally funded. Spending is actually split between the states and the federal government. He went on to describe the premiums and deductibles as being too high when, except in very rare cases, Medicaid enrollees do not pay either of those types of fees.
Fluoride in Water
Mr. Kennedy referenced a recent study that found an association between fluoride and I.Q. — research that he felt vindicated his earlier concerns about the dangers of fluoridated drinking water.
While the description of the study’s findings was accurate, there are notable caveats.
The study, by scientists from the federally funded National Institute of Environmental Health Sciences, was an analysis of dozens of fluoride studies, which found higher fluoride exposures were linked to lower I.Q. scores.
However, researchers cautioned that none of the studies included in the analysis were conducted in the United States, where recommended fluoridation levels in drinking water are very low. At those amounts of fluoride, evidence was too limited to draw definitive conclusions.
The C.D.C. has noted that its experts “have not found convincing scientific evidence” linking community water fluoridation with adverse health effects.

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.”

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.
