A Wisconsin doctor is gearing up for the feat of a lifetime in order to spread awareness about the most pervasive cancer impacting young men.

Dr. T. Clark Gamblin, a surgeon in Milwaukee, spoke with Fox News Digital about his upcoming participation in the World Marathon Challenge. The competition involves running seven marathons on seven continents – seven days in a row. 

The first marathon will take place in Antarctica on Jan. 31, 2025. From there, Gamblin and other participants will travel to Cape Town, South Africa; Perth, Australia; and Dubai, UAE.

From there, Gamblin will jet to Madrid, Spain, and Fortaleza, Brazil, before running a final race in Miami. He and his fellow marathon runners will have logged 183 miles over the course of a week.

The fast-paced nature of the competition means that it won’t exactly be a relaxing vacation for the participants.

“Over the course of the seven days, we’ll spend about 60 hours on the plane,” Gamblin said. “So it’s running, and it’s plane, and it’s running, and then it’s plane.”

“If you’re prepared and you train correctly, it’s not some Herculean feat.”

While it may seem physically impossible for a human to run seven marathons in seven consecutive days, the World Marathon Challenge has taken runners across the world for nearly a decade. Gamblin began training for the race a year ago.

“It’s a physical challenge, there’s no doubt about it, but there are much more physically demanding things that people have done,” he said. “If you’re prepared and you train correctly, it’s not some Herculean feat.”

Gamblin has a whole team behind him. The World Marathon Challenge organization handles the logistics of all participants’ flights and hotels. A cancer surgeon, Gamblin also enlisted the help of a dietitian at his hospital to help him meet his protein and fluid goals.

He also has a physical trainer to help with injury prevention — but the person who has helped Gamblin the most, he said, is his wife.

“She’s like my No. 1 cheerleader,” Gamblin said. “She’s not a big runner, but she’s a huge part of helping me get ready for this and preparing me for it.”

“But then right behind her would be my running coach, a dietitian and a physical therapist. So it does take a team to get ready for something like this.”

Gamblin, who specializes in liver and bile duct cancer, became interested in running marathons as a medical school student. During the World Marathon Challenge, he will be running for the Testicular Cancer Awareness Foundation. 

The cause is near to his heart, as Gamblin is a cancer survivor himself – he was diagnosed with testicular cancer in 2018 after noticing a lump.

“I thought it was probably nothing, but I was really diligent about it and checked it out very quickly and discovered it was testicular cancer,” he explained. “And testicular cancer is the No. 1 cancer that affects males aged 15 to 45.”

One out of every 250 men will develop testicular cancer in their lifetime, according to the Testicular Cancer Awareness Foundation.

“I went from being a cancer surgeon and giving all this advice, to having to take the advice I had been giving and apply it in my own life,” Gamblin noted. 

“The most intriguing one is the Antarctica race … it’s going to be such a unique environment and climate to run in.”

After going through chemotherapy and two operations, he has now been cancer-free for four years.

Gamblin’s desire to spread awareness has fueled the long and arduous training he has gone through to prepare for the 168-hour-long feat. 

Despite the challenges, he said he looks forward to the simple pleasures of the race, such as getting to know his fellow runners.

Gamblin will run a marathon on every continent, including Antarctica, starting in January. (Jan Gamblin, Ph.D.)

“It’ll be such a unique group of people, too,” he said. “I’m prepared to make some lifetime friendships and hear other people’s stories.”

Gamblin is documenting his marathon journey through his Instagram account, @tclarkgamblin. He’s most excited about running through Antarctica.

“So few people have run marathons there,” he said. “It’s going to be such a unique environment and climate to run in.”

In Miami, Gamblin will get to see his family at the finish line.

Gamblin said that he hopes his story encourages others to achieve their potential. (Jan Gamblin, Ph.D)

“I think that far too often, we don’t set our goals high enough in life,” the doctor said. “We don’t risk enough …This is a risk, it is a reach for me.”

The doctor said he aims to inspire other people to also set their sights higher than they normally would.

“Your body will in many cases do what the mind tells it to do,” Gamblin added. 

“And so I think we can challenge ourselves and push ourselves far beyond … the limits that we set.”

Excess fat has been linked to many health conditions, even some that impact the brain.

In the latest Alzheimer’s research, hidden fat in various parts of the body was shown to be an early warning sign of the most common dementia — as long as 20 years prior to symptoms emerging.

The study findings were presented this week at the annual Radiological Society of North America (RSNA) meeting in Chicago.

“This crucial result was discovered because we investigated Alzheimer’s disease pathology as early as midlife — in the 40s and 50s — when the disease pathology is at its earliest stages, and potential modifications like weight loss and reducing visceral fat are more effective as a means of preventing or delaying the onset of the disease,” said lead study author Mahsa Dolatshahi, M.D., post-doctoral research associate at Mallinckrodt Institute of Radiology (MIR) at the Washington University School of Medicine, in a press release.

In the study, researchers assessed 80 middle-aged adults (averaging 49 years old) who did not have any cognitive impairment, according to the release.

Just over half of the people were categorized as obese. The average body mass index (BMI) was 32.31, with anything over 30 falling into the obesity category.

POOR SLEEP IN MIDDLE AGE COULD AFFECT THE BRAIN IN A SURPRISING WAY, STUDY FINDS

The researchers assessed the potential connection between signs of Alzheimer’s disease and controllable lifestyle factors, including obesity, metabolic health and BMI.

Tests included brain scans, body MRIs, cholesterol panels, and measurements of blood glucose and insulin levels.

Beyond just measuring BMI, the study used MRI technology to look closer at body fat and better determine its relationship to Alzheimer’s, the release noted.

“We investigated the association of BMI, visceral fat, subcutaneous fat, liver fat fraction, thigh fat and muscle, as well as insulin resistance and HDL (good cholesterol), with amyloid and tau deposition in Alzheimer’s disease,” said Dolatshahi.

An additional finding was that higher insulin resistance and lower HDL were associated with high amyloid in the brain, which is a hallmark of Alzheimer’s.

“A key implication of our work is that managing Alzheimer’s risk in obesity will need to involve targeting the related metabolic and lipid issues that often arise with higher body fat,” said senior study author Cyrus A. Raji, M.D., Ph.D., associate professor of radiology at MIR, in the release.

In a separate study that is also being presented this week, the same research team investigated how obesity and belly fat can impair blood flow to the brain.

Three out of four Americans are overweight or obese, the researchers noted.

Meanwhile, approximately 6.9 million Americans, aged 65 and older, have been diagnosed with Alzheimer’s disease, a number that has been predicted to reach 13 million by 2050.

“The good news is these risk factors can be lowered with a healthy lifestyle and routine exercise.”

Dr. Earnest Lee Murray, a board-certified neurologist at Jackson-Madison County General Hospital in Jackson, Tennessee, was not involved in the study but commented on the results.

“We have known for some time the dangers of visceral fat on various organs of the body, likely from its facilitation of inflammatory changes — and it’s no different in the brain,” he told Fox News Digital.

What stuck out most to Murray was how early in life the changes are noted in the brain.

“The good news is these risk factors can be lowered with a healthy lifestyle and routine exercise,” he said.

The popularity of GLP-1 medications for diabetes and obesity “will most certainly be studied” in this context as well, Murray added.

“This study also shows the importance of physicians and insurance companies focusing on prevention and the long-term benefits of modifying risk factors at an early age, as opposed to waiting for patients to develop symptoms.”

Your dentist may remind you to brush, floss and mouthwash – but what is the “right” order to do it?

While all steps of oral hygiene can benefit dental health, Dr. Mike Wei, DDS, of New York City, shared with Fox News Digital that he’d recommend the below order.

1. Floss

2. Brush

3. Mouthwash

‘I’M A DENTIST – HERE’S WHY YOU SHOULD NEVER KEEP YOUR TOOTHBRUSH NEAR THE TOILET’

Starting with floss helps to remove food debris and plaque between the teeth and along the gumline, which a toothbrush “may not reach effectively,” according to Wei.

“By flossing first, you can dislodge particles and bacteria from these tight spaces, making it easier for the toothbrush and mouthwash to clean the remaining surfaces of your teeth,” he said.

Next, brushing with a fluoride toothpaste can help remove plaque, bacteria and food particles from the surface of the teeth, the dentist advised.

“By brushing after flossing, you are able to remove any particles that were loosened during flossing and ensure that all visible surfaces of your teeth are thoroughly cleaned,” Wei said.

Following up with an antimicrobial mouthwash can help further kill bacteria and reduce plaque buildup.

Mouthwashing at the end can also help freshen the breath and reach areas that brushing or flossing may have missed, Wei noted.

“Overall, following this order of flossing, brushing and using mouthwash can help to ensure a comprehensive cleaning of your teeth and gums, leading to better oral hygiene and a reduced risk of dental issues, such as cavities and gum disease,” he said.

WOMEN EXPERIENCE MORE DENTAL HEALTH ISSUES THAN MEN, EXPERTS SAY

This recommended sequence is common practice among dental professionals to achieve optimal oral health, including reduced risk of cavities and gum disease, Wei added.

Dr. Ellie Phillips, DDS, an oral health educator based in Austin, Texas, took it a step further, noting that a mouth rinse can act as a “cleanser” for the teeth before brushing.

Excessive use of mouthwash containing alcohol may lead to dry mouth and irritation, according to one expert. (iStock)

Rinsing with salt water or alternative mouthwashes like chlorine dioxide helps to remove any acidity from food and drink particles and prevent them from being brushed into the teeth, she told Fox News Digital.

After brushing with toothpaste and “massaging” the gums with a toothbrush to stimulate circulation, then it’s time to floss, Phillips said.

Flossing after brushing “will get toothpaste between your teeth,” she cautioned.

But the expert also warned that “a lot of floss contains PFAS chemicals,” which people should avoid pushing into their gums.

After flossing, Phillips recommends rinsing with a traditional mouthwash, which studies have shown can be “five times more effective than flossing” just by swishing it through the teeth for a few seconds.

Rinsing with water, especially with natural fluoride, at the end of an oral care routine can help absorb minerals into the teeth, according to Phillips, author of the upcoming second edition of her book “Kiss Your Dentist Goodbye.”

While there are “minimal risks” to basic oral care, Wei warned that excessive use of mouthwash containing alcohol could lead to dry mouth and irritation.

“It’s important to choose products recommended by dental professionals and follow instructions for proper use,” he said.

“Remember to consult with your dentist for personalized recommendations based on your oral health needs.”

Rhubarb is a vegetable that visually appears to resemble celery in texture — but its color and taste are differentiating factors between the two. 

Rhubarb has an extremely tart flavor, and it is very rarely eaten on its own due to its sour notes. It’s often combined with sugar in sweet treats like pie or jam. 

Even though rhubarb is often used in desserts, it’s actually full of health benefits.

While combining rhubarb with sugar may not be the healthiest approach to take, there are plenty of other healthy ways to counteract rhubarb’s sour flavor. 

Find out more about the health benefits of rhubarb and how you can easily incorporate it into your diet below. 

1. Improves bone health
2. Is rich in antioxidants
3. Aids digestion
4. Can help regulate blood pressure
5. Has the potential to lower bad cholesterol levels

1. Improves bone health

There are many different vitamins present in rhubarb. 

One of these is vitamin K, an important contributor to overall bone health as well as blood clotting. 

POTENTIAL HEALTH BENEFITS OF TARRAGON, INCLUDING IMPROVED DIGESTION, ACCORDING TO EXPERT

“Just one cup of rhubarb has almost half of your vitamin K needs,” Lauri Wright, associate professor of nutrition and dietetics at the University of South Florida and registered dietitian nutritionist, told Fox News Digital. 

Wright added that though most people don’t take Coumadin anymore for blood thinning, those who are on medication should be extra cautious of rhubarb consumption since vitamin K and Coumadin don’t interact well.

Calcium is also apparent in rhubarb, another contributor to bone health, as well as vitamin C, great for a nice immune boost.

“It’s also rich in calcium, which helps with bone health, and vitamin C, which boosts your immunity and is involved in collagen production for healthy skin and tissues,” Wright said. 

2. Is rich in antioxidants

Rhubarb is full of antioxidants.

The antioxidants in rhubarb do far more than just give the vegetable its color. 

“Rhubarb is really high in antioxidants, and those are kind of these compounds that give the rhubarb its reddish color, but those compounds in the body help take down inflammation and protect the cells from damage… some of the damage that could eventually lead to cancer cells,” Wright explained.

3. Aids digestion

Rhubarb is a vegetable high in fiber. 

“[Rhubarb is] rich in fiber, so it really helps with digestion. [It] has a pretty good source of fiber per serving,” Wright told Fox News Digital.

That said, the amount of fiber in rhubarb shouldn’t lead to any GI issues, Wright added. 

The part of the vegetable to be mindful of is the leaves. While rhubarb stalks boast impressive health benefits, the leaves should be left alone. 

“The leaves actually contain oxalic acid, which, if you eat a lot of it, can be toxic, and it also, for some people, can build stones in the kidneys. So you always want to trim the leaves before you cook the rhubarb,” Wright noted.

4. Can help regulate blood pressure

Rhubarb has the potential to regulate blood pressure.

The high potassium content in the vegetable is what strongly contributes to this potential health benefit, Wright told Fox News Digital.

“It’s high in potassium,” Wright said. “Potassium helps regulate blood pressure [and] helps with better blood pressure control.”

5. Has the potential to lower bad cholesterol levels

Rhubarb stalks may have the capability to lower bad cholesterol levels.

“Studies have actually shown that rhubarb stalks can help lower the LDL cholesterol, or the bad cholesterol … just a few, but there’s some promise there,” Wright said. 

If you want to begin to incorporate rhubarb into your diet in a healthy way to see all of its potential benefits, one easy way to do so is by using it as an ingredient in salsa.

“One really fun idea is [to] add rhubarb to your salsa,” Wright said. “Dice up rhubarb along with mango, red onion, lime juice, cilantro. That makes a really tangy salsa, and it’s perfect to put on top of grilled fish or chicken.”

Another easy way to incorporate pretty much any fruit or vegetable into a diet is by blending it into a smoothie.

“Add rhubarb to your smoothie with strawberries, Greek yogurt, a little drizzle of honey and maybe some spinach, and that’s going to be like a really fun mix of flavors that is packed with nutrition,” Wright explained. 

A nutrient-rich smoothie is a super simple way for those who have a hard time meeting daily recommended intakes of fruits and vegetables to get the vitamins and minerals they need.
