Childhood medical myths debunked as experts weigh in on 5 common warnings
Mothers might know best, but it’s not always easy to separate fact from fiction when it comes to health advice.
A new report from University of California San Francisco (UCSF) Health has broken down several common wellness myths that children often hear while growing up.
Fox News Digital spoke with experts who revealed the truth behind common medical misconceptions.
PSYCHOLOGISTS REVEAL 7 WAYS PARENTS CAN DRIVE HAPPINESS BY HELPING KIDS FIND THEIR PURPOSE
Here are five.
Myth 1. Ginger ale relieves stomach aches
While actual ginger can help ease a stomach ache, most commercial ginger ales don’t actually contain the real thing, Michelle Jaelin, a registered dietitian practicing in Ontario, Canada, told Fox News Digital.

This childhood myth persists as parents give ginger ale to children because it’s sweet and bubbly, she said.
“It makes parents feel better that they are doing something for their child when they aren’t feeling well, and the myth persisted as a drink that helps a stomach ache,” Jaelin said.
The carbonated beverages could actually make the stomach pain even worse by increasing gas in the digestive tract, according to Healthline’s website.

Drinks with real ginger also tend to contain excess added sugar, experts said – essentially the equivalent of soda that may worsen stomach pain.
Myth 2. Gum stays in your stomach for seven years
“Swallowed gum does not stay in your stomach for [seven] years, as the myths suggest,” Su-Nui Escobar, a registered dietitian based in Miami, Florida, told Fox News Digital.
“While swallowing gum is not recommended, if you do so accidentally, you will likely pass it like any other indigestible food.”
ASK A DOCTOR: ‘IS IT DANGEROUS TO SWALLOW GUM?’
The gum will pass through the stomach within two hours and be excreted in the stool after approximately two to five days, just like other foods, according to the recent UCSF report.
Although chewing gum can stick to many surfaces — including walls or desks — it travels mostly intact through the gastrointestinal tract without sticking to the intestinal walls, the report notes.
“Swallowed gum does not stay in your stomach for [seven] years, as the myths suggest,” an expert told Fox News Digital. (iStock)
But experts still caution against children swallowing gum, because substantial amounts might cause an intestinal blockage, Escobar warned.
This is a particular concern among children who have underlying constipation, according to Mayo Clinic’s website.
“If you suspect a blockage, seek immediate medical attention,” Escobar advised.
Myth 3. You shouldn’t swim for 30 minutes after eating
As summer kicks into high gear, there is good news for any swimmer itching to get in the water after lunch. Yes, it is usually OK to swim right after you eat.
The myth that you shouldn’t swim immediately after eating stems from a theoretical concern that blood flow will be diverted away from the arms and legs to help digest food, potentially leading to an increased risk of drowning.
“Based on current research, eating before swimming is not affiliated with a risk of drowning, and can be dismissed as a myth.”
But a comprehensive American Red Cross scientific review on the effects of eating before swimming showed no effect on performance in the water after a meal.
“A recent literature review did not provide any information related to an increased risk of drowning due to consuming food before swimming,” Jodi Jensen, PhD, member of the American Red Cross Scientific Advisory Council in Virginia, told Fox News Digital.
AS DROWNING DEATHS INCREASE, EXPERTS OFFER WATER SAFETY TIPS
“There is no supporting evidence from a major medical or safety organization that recommends refraining from eating before engaging in aquatic activities such as swimming,” added Jensen, who is also an assistant professor and aquatics director at Hampton University in Hampton, Virginia.

“Based on current research, eating before swimming is not affiliated with a risk of drowning, and can be dismissed as a myth.”
Although study participants experienced “minimal” side effects at different time intervals after eating, some outside experts do recommend waiting a bit after a meal if you plan to swim laps or compete to avoid any stomach cramping or digestive issues.
Myth 4. Chicken soup cures a cold
Chicken soup has been viewed as a popular cold remedy since at least the 12th century, according to the National Institutes of Health (NIH).
ASK A DOCTOR: ‘DOES CHICKEN SOUP REALLY HELP CURE A COLD?’
“Chicken soup is warm and comforting when you’re sick, but it’s not a cure,” Jaelin told Fox News Digital.
“Chicken soup is warm and comforting when you’re sick, but it’s not a cure.”
“Drinking any hot broth when your sinuses are stuffed can help to clear them out.”
The steam from the chicken broth may relieve a sore throat and congested sinuses, the NIH noted.

When battling a cold, get plenty of clear fluids to help regulate body temperature and promote improved immune system function, said Jaelin.
“Chicken soup counts toward overall fluid intake,” she added.
It also helps prevent dehydration and clear out mucus, the NIH noted.
Myth 5. You will ruin your eyes if you sit too close to the TV
Sitting too close to the TV will not damage your eyes, though it may cause eye strain, according to the American Academy of Ophthalmology.

To prevent eye strain while watching television, experts recommend keeping the room well-lit and taking occasional breaks from the screen.

“Children can focus at very close distances better than adults, and may not develop the same eye strain symptoms,” Nishika Reddy, M.D., assistant professor of ophthalmology at Moran Eye Center’s Midvalley Health Center at University of Utah in Murray, Utah, told Fox News Digital.

It may be a red flag, though, if children are watching television too closely, experts warned.
The behavior may indicate an underlying vision issue that should be addressed, the UCSF report noted.
The American Academy of Pediatrics says high-quality digital media can be introduced to children between 18 and 24 months of age (only when supervised by parents or caregivers). The academy also recommends limiting screen time to one hour a day for children ages 2 to 5. (iStock)
“See an eye care provider to perform an eye exam for your child,” Reddy recommended.
A more concerning issue is the indirect effect of too much screen time, according to the report.
Although experts say there is no one-size-fits-all guideline when it comes to children and screen time, the American Academy of Pediatrics says high-quality digital media can be introduced to children between 18 and 24 months of age (only when supervised by parents or caregivers).
The academy also recommends limiting screen time to one hour a day for children ages 2 to 5.

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.

“If we take the fraud out, we could double the life expectancy, which means you, your kids, your kids’ kids … they could all benefit from this beautiful safety net program.”
