This odd dental habit could spark heart health risks, experts warn

Searches for “tongue scraper” have almost doubled in the last two decades, according to Google Trends. Some experts, however, have warned about potential risks.

The practice of tongue-scraping (or tongue-brushing) has existed as a means of dental health for hundreds of years. 

While earlier studies concluded that scraping the tongue can improve one’s sense of taste in as little as two weeks, some have raised concerns about potential heart health risks associated with the practice.

HERE’S HOW YOU SHOULD BE CLEANING YOUR TEETH, ACCORDING TO A DENTIST

“There’s always been a strong association between good oral hygiene and heart health,” Dr. Bradley Serwer, an interventional cardiologist and chief medical officer at VitalSolution, an Ingenovis Health company, told Fox News Digital.

“Gingivitis or a bad gum infection has been known to cause problems with the heart on many different levels,” said the Maryland-based doctor.

Despite the potential benefits, Serwer and others have warned of a little-known cardiac risk associated with the practice.

What is tongue-scraping?

Tongue-scraping (or brushing) is the process of cleaning the tongue to keep bad bacteria, food debris and dead cells from accumulating on its surface, according to Cleveland Clinic.

Beyond brushing with a toothbrush, specific tongue-scraping tools — available at pharmacies for as little as $8 — offer an easy way to get rid of plaque and other unwanted build-up.

“Brushing is OK to do, but think about it this way — if your carpet is dirty and you scrub it, the dirt’s going to get embedded down in there,” said one dental hygienist. (iStock)

Gentle tongue-scraping performed up to once a day is recommended for adults to help remove bacteria and freshen breath, according to Dr. Whitney White of Aspen Dental.

“When patients ask, I typically recommend a metal tongue scraper, as they are the best for hygienic reasons to keep clean,” White, who is based in Nevada, told Fox News Digital.

Another expert, Ohio-based dental hygienist Tenika Patterson, told Cleveland Clinic, “Tongue-scraping can do a better job at removing that plaque and bacteria from the tongue’s surface.”

“Brushing is OK to do, but think about it this way — if your carpet is dirty and you scrub it, the dirt’s going to get embedded down in there,” she said.

“But if you scrape it, it’s going to come right off the surface.”

Link to heart health

The concern with tongue-scraping is that it can cause “macroscopic cuts” on the tongue, which potentially can introduce bacteria into the bloodstream, Serwer cautioned.

Any time bacteria enters the bloodstream, there is an increased risk of endocarditis, which is an infection of the heart valves.

If left untreated, endocarditis can lead to severe heart damage, according to Cleveland Clinic.

Too much tongue-scraping can lower the body’s nitric oxide levels and increase the risk of issues like high blood pressure, an expert warned. (iStock)

While tongue-scraping can be good for oral health, it’s important not to overdo it, Dr. White advised.

“While gentle, regular scraping helps remove harmful bacteria, doing it too often or too aggressively can disrupt the balance of good microbes on your tongue — some of which help produce nitric oxide, a compound that’s important for heart health,” White said.

‘Not a substitute’

“The most important thing a person can do is to stay on top of oral hygiene,” Serwer recommended. 

“Regular visits to the dentist, brushing and flossing can help ensure healthy gums and teeth.”

While brushing teeth and flossing can also introduce bacteria, those are outweighed by the benefits of maintaining healthy gums, experts agree. (iStock)

While brushing teeth and flossing can also introduce bacteria, those are outweighed by the benefits of maintaining healthy gums, experts agree.

In contrast, “the benefits of tongue scraping are quite minimal,” Serwer said.

For those who wish to continue tongue-scraping, White emphasized that less can be more.

“Since your oral health is connected to your overall health, it’s best to scrape your tongue in moderation to keep both your mouth and body in balance,” she advised.

“However, it is not a necessary step in your oral health routine, and should not be a substitute for twice-daily brushing with fluoride toothpaste and daily flossing.”

Health experts react as Andrew Huberman backs Trump admin’s new food pyramid

NEWYou can now listen to Fox News articles!

The Trump administration has taken a new approach to the food pyramid.

The Department of Health and Human Services (HHS) announced new guidelines on Wednesday with an updated, inverted pyramid. The top of the pyramid, which is now the wider part of the structure, is built on meat, fats, fruits and vegetables, while whole grains are at the narrow bottom.

This follows HHS Secretary Robert F. Kennedy Jr.’s mission to “Make America Healthy Again” (MAHA), aimed at addressing chronic disease, childhood illnesses and ultraprocessed foods.

“The new guidelines recognize that whole, nutrient-dense food is the most effective path to better health and lower health care costs,” Kennedy said during a press briefing in Washington, D.C. 

“Protein and healthy fats are essential, and were wrongly discouraged in prior dietary guidelines. We are ending the war on saturated fats.”

The HHS secretary rallied against refined carbohydrates, food additives and added sugar, highlighting the health risks associated with sugar-sweetened beverages. 

Kennedy’s main message to Americans was to “eat real food.”

The announcement triggered reactions from top health and wellness voices, including Stanford neuroscientist Dr. Andrew Huberman, host of the “Huberman Lab” podcast.

In a post on X, Huberman shared the White House’s graphic of the new pyramid, praising the decisions that were made.

“Oatmeal (and I think that’s rice and sourdough) made the cut!” he commented. “In all seriousness, assuming overall calories are kept in check and people exercise & get sun(day)light, this looks spot on.”

He added, “Maybe up the veggies a bit, add low-sugar fermented foods like sauerkraut & this is great.”

Huberman said in a thread on the same post that Americans “don’t have to eat all the foods” shown in the diagram.

“You won’t see me drinking milk or eating shrimp,” he said. “Nothing against shrimp, I just don’t like the taste. Aversion to crustaceans.”

The new guidelines received praise from other major health figures, including former FDA commissioner Dr. David Kessler.

“There should be broad agreement that eating more whole foods and reducing highly processed carbohydrates is a major advance in how we approach diet and health,” Kessler told The Associated Press.

“Protein and healthy fats are essential, and were wrongly discouraged in prior dietary guidelines.”

Dr. Bobby Mukkamala, president of the American Medical Association, shared in a statement that these guidelines “affirm that food is medicine and offer clear direction patients and physicians can use to improve health.”

“The American Medical Association applauds the Administration’s new Dietary Guidelines for spotlighting the highly processed foods, sugar-sweetened beverages and excess sodium that fuel heart disease, diabetes, obesity and other chronic illnesses,” Mukkamala wrote.

But not all feedback was positive.

Some people expressed concern about prioritizing red meat and dairy, while calling for the limitation of saturated fat.

Neal Barnard, president of the Physicians Committee for Responsible Medicine, shared in a reaction to STAT that while the guidelines “do have one or two good points, emphasizing fruits and vegetables and limiting alcohol,” the guidelines are “for the most part a strong reflection of industry influence.”

Christopher Gardner, a nutrition expert at Stanford University, also spoke out against the new guidelines, as reported by NPR.

“I’m very disappointed in the new pyramid that features red meat and saturated fat sources at the very top, as if that’s something to prioritize. It does go against decades and decades of evidence and research,” said Gardner, who was a member of the Dietary Guidelines Advisory Committee.

Deadly cancer risk could drop with single 10-minute workout, study suggests

NEWYou can now listen to Fox News articles!

A single 10-minute workout may trigger blood changes that help fight colon cancer.

That’s according to new research from scientists at Newcastle University, who found that exercise quickly changes the blood in ways that affect colon cancer cells in the lab.

In the study, the U.K. researchers exposed colon cancer cells to human blood serum collected immediately after exercise, finding that the cells repaired DNA damage faster and showed gene activity patterns linked to slower growth.

The blood samples came from 30 adults who had just completed a short, high-intensity cycling workout that lasted about 10 to 12 minutes, according to a press release.

Even a 10-minute burst of intense exercise may send protective signals through the blood that affect colon cancer cells, researchers say. (iStock)

Samuel T. Orange, an associate professor at Newcastle University and one of the study’s authors, spoke with Fox News Digital about the findings.

“Our findings show that exercise rapidly triggers molecular changes in the bloodstream that can act directly on colon cancer cells, reshaping gene activity and supporting DNA damage repair,” he said.

The results suggest that even brief activity can make a difference. “Every movement matters. Exercise doesn’t need to last hours or happen in a gym,” Orange added.

One of the most surprising findings, according to the researcher, was how strong the biological response was after even a single workout.

“Exercise altered the activity of more than 1,000 genes in colon cancer cells,” he shared.

Even brief bouts of activity can make a difference, the researcher said.  (iStock)

The study findings suggest that the effect is driven by exercise-triggered molecules released into the bloodstream, sometimes referred to as “exerkines,” which act like chemical messengers and send signals throughout the body.

“Each time you exercise, you trigger biological signals that support health and resilience to diseases such as cancer, diabetes and heart disease,” Orange said.

The researchers cautioned that the study was conducted using cancer cells grown in the laboratory, not in patients.

“These findings now need to be replicated in people with cancer,” Orange said. “We also need to better understand the longer-term effects of repeated exercise signals over time.”

Despite the limitations, the researcher said the findings strengthen the case for exercise as an important part of colon cancer prevention.
