So many young people with colon cancer have clean diets. What gives?

  • Increasingly, young people with clean diets and healthy lifestyles are getting colon cancer.
  • Doctors say diet plays a role in the rising risk, but doesn't tell the whole story.
  • We are learning more about ways microplastics, sleep cycles, and our environment may play a role.

At 30, Chris Lopez was hitting his stride. He was attending culinary arts school in Dallas. He was meal prepping and hitting the gym regularly, focused on getting a degree and setting up his life right.

His symptoms were easy to dismiss, at least at first. "I had a real bad stomach ache that was going on for about a month," he told Business Insider. "I thought, 'Oh, maybe I ate some sushi, some fish or something that was undercooked.'"

Except food poisoning doesn't typically last for weeks on end, and doesn't leave blood in your stool. He rapidly lost weight, from 175 pounds to 145 in a single summer β€” without eating less. "I was pretty much like a skeleton," he said.

Lopez went to his doctor, who eventually decided to do a colonoscopy to learn more. That's when they discovered a "grapefruit-sized" tumor in his colon, he said. Lopez saw the scan and couldn't believe his eyes. Colon cancer? He was so young, healthy, and fit.

Stories like Lopez's are increasingly common. Colon cancer rates are rocketing among athletic young people in their 20s, 30s, and 40s, and survival rates are dropping.

Take Chris Rodriguez, a 37-year-old improv actor and CrossFit enthusiast who adheres to a high-fiber, high-protein diet, with plenty of veggies. He was 35 when he was diagnosed with stage 3 rectal cancer.

"The question pops in your mind, 'What else was I supposed to do?'," Rodriguez told BI. "That's really the unfortunate thing with a diagnosis like this, is there isn't really much else that you're supposed to do, outside of looking for symptoms."

The most convenient explanations for the rise in young colon cancer are diet and weight. We know diet can influence colorectal cancer risk, and it's something people can fix, to a degree. Plus, our diets have changed. These days we all consume more sugar, more ultra-processed foods, more oil and butter, while moving less.

Still, doctors say the trend we're seeing now defies neat categories of genetics or lifestyle, and it's baffling. Other factors are clearly messing with our digestive systems, but they're tough to pinpoint. Pollution, microplastics, and artificial light β€” all are pervasive in society, yet very tricky to study.

Thanks to recent research, we are starting to get a better picture of why young colon cancer cases are rising, and we're on the cusp of some pretty big results that may uncover better ways to prevent and treat it.

Young colon cancer is getting deadlier and more common

Something shifted in the 1960s. Everyone born after 1960 has a higher colon cancer risk than previous generations. This phenomenon is known as the "birth cohort effect."

"The rise that we're seeing cannot just be accounted for by inherited differences," Dana Farber colon cancer researcher Dr. Marios Giannakis told BI.

In the US, young colon cancer rates have been rising about 3% every year since the early 1990s, according to National Cancer Institute data.

"We do think since genetics haven't changed, the cancers that are increasing are environmentally based," Dr. William Dahut, the chief science officer at the American Cancer Society, said during a recent briefing to reporters. "Exactly what's doing it is really β€” more research is needed."

The biggest cancer centers in the US are opening units to investigate this trend. In 2018, Memorial Sloan Kettering in New York opened a first-of-its-kind center for "young-onset" colorectal cancer patients. Dana Farber in Boston, Mass General, MD Anderson Cancer Center, and Columbia University Irving Medical Center followed close behind, all opening special programs for young colon cancer cases.

In 2021, the CDC took action, lowering the age of recommended colon cancer screening from 50 to 45. It's an effort to catch more young colon cancer cases sooner, upping the odds of people surviving.

It isn't a uniquely American issue. Wealthy countries, in particular, are seeing similar spikes. New Zealand, Chile, Norway, and Turkey are among 27 countries recording record-high rates of young colon cancer.

Diets matter β€” to an extent

It's hard to dismiss the role our changing food landscape has played. We are undoubtedly eating worse than our grandparents did 100 years ago.

Take fiber, for example. Found in abundance in whole plant foods like beans, it is a nutrient clearly associated with lower risk of cancer.

Some of the most popular foods in US supermarkets β€” prepackaged for our convenience β€” tend to have fiber stripped out during processing, and extra salt, sugar, and oils added in to make them more palatable and shelf-stable.

It started in the aftermath of World War II, when industrial processing and factory farming took hold nationwide.

"Essentially we redeployed what had allowed the United States and allies to prevail in that war to non-military applications, and it completely transformed agriculture," Dr. David Katz, a leading expert in chronic disease prevention and nutrition, told BI.

"You only have a certain total number of calories you can eat per day, and if a higher percentage of those is made up of hamburgers and Pop-Tarts, then a lower percentage ipso facto is made up of lentils and all the other good stuff."

Ultra-processed foods now account for a significant proportion of what we eat. Excess sugar, salt, and chemicals lurk in pasta sauce, breakfast cereals, and salad dressing. Brown bread labeled "heart healthy" can have a higher sugar content than white Wonderbread.

Upsetting the balance of nutrients in our guts has consequences. Compounds that aren't necessarily harmful in moderation, like omega-6 fatty acids from seed oils, take up a disproportionate part of our diets. That can lead to inflammation, infection, and diseases like diabetes, heart disease, and, yes, colon cancer.

Your microbiome is not just about what you eat. It's influenced by myriad factors, from how you were born to your work schedule.

What else is going on?

Doctors and lab scientists who spoke to BI for this story all said the rise in millennials getting colon cancer likely won't be attributed to one single thing.

Shuji Ogino, an epidemiology professor at Harvard Medical School, has been studying young colon cancer cases across the world. He published a study in Nature that showed the early life "exposome" β€” diet, lifestyle, environment, exposures β€” has changed dramatically, becoming conducive to cancer.

We've introduced lots of new things to our environment without knowing the ramifications. Now, we're starting to see the long-term effects.

Something as simple as artificial light could play a role. "That's something no human being experienced 200 years ago," Ogino said. Lights allow us to work and socialize at all hours, impacting how our body clocks regulate hormones and metabolism.

Dr. Heinz-Josef Lenz, co-lead of the gastrointestinal cancer program at the University of Southern California cancer center, is also studying how the environment may be damaging our DNA in ways we don't yet understand.

His data so far suggests the trend of more younger folks developing colon cancer isn't genetic, but our genes may affect how we respond to our exposures β€” the processed food we eat, the antibiotics we take, and the polluted air we breathe.

"When you are 16 years old or 20 years old, you cannot blame it on diet or exercise or obesity β€” it's just too short," he said. "We're just scratching the surface on better understanding the impact of the parents, particularly in the young onset: was their exposure part of it, or not?"

Here are five things we're learning:

1. Sleep cycle

We can't separate gut health from our internal clock.

Gut bacteria help regulate sleep, which cuts cancer risk.

Emerging evidence suggests that disrupting the circadian rhythm creates problems in the gut that can contribute to colon cancer, according to studies in mice and data in humans. Our sleep can be derailed by late schedules and artificial light from our homes and phones, which may be one factor in rising colon cancer cases.

2. Microplastics in air and water

Increasingly, researchers are finding evidence that microplastics play a negative role in fertility.

They can also be pro-inflammatory, driving diseases like cancer and obesity, hurting lungs, and possibly helping cancer to thrive in the body.

A new evidence roundup from researchers at UCSF analyzed 22 studies that compared microplastic exposure to health problems in mice and people, and found that all of them showed some harm.

"We basically saw this continuous effect that the more you get exposed to it, so in our environment, the more it gets produced, the greater the health harm," Nicholas Chartres, one of the study's authors and a former head of the science and policy team at UCSF's program on reproductive health and the environment, told BI.

Chartres says the time is now to act to reduce our microplastic exposure, and it must be done at a policy level. At home, Chartres runs around the house throwing out his kids' plastic toys, but he knows he's playing a losing game of environmental whack-a-mole.

"We don't need to have specific quantification of the level of harm, there's enough here to show that they're certainly contributing," he said.

3. What your parents were exposed to

Lenz is conducting research that aims to unravel why so many Hispanic patients in Southern California seem to be especially at risk of developing early colon cancer.

His team is studying cancer patients' blood, DNA damage, lifestyles, and ZIP codes to pinpoint where their exposure risks might be coming from, whether it be overuse of antibiotics, pollution that families are exposed to, or something else.

"It could be an epigenetic event, not only from the patient itself but from the family, from the parents and their exposure," he said. "Epigenetics can be influenced by lifestyle and by exposure to chemicals, or whatever it is that will actually react."

4. Antibiotics

It is well established that antibiotics disrupt the gut microbiome, killing off some beneficial bacteria. And humans aren't the only antibiotic consumers.

Most of the antibiotics (73%) in use worldwide are for meat production, recent research suggests. Some meat advertised as antibiotic-free has failed independent testing.

Red meat consumption ups a person's colon cancer risk, and so does antibiotic use, but these two factors aren't necessarily separate.

5. C-section

Newborns are exposed to trillions of their mother's microbes as they travel through the birth canal, giving an infant's microbiome an initial boost. Kids who are delivered through the abdomen via cesarean section don't get those same health benefits.

Recent research from Sweden suggests girls who are born via c-section have a higher risk of developing young colon cancer than those born vaginally.

Major colon cancer discoveries coming in 2025-2026

In 2024, a group of international researchers mapped 1.6 million cells in the gut to create the most comprehensive picture to date β€” the "gut atlas."

"It's rare that any one study squeezes out all the relevant biological insights," Ivan Vujkovic-Cvijin, a professor of medicine at Cedars-Sinai Medical Center, who was not involved in the study, told Business Insider.

"By identifying which components of tissue function are dysregulated in disease, the scientific community can design drugs to restore those functions," he said.

There's more to come. Multiple big, well-funded multinational studies are underway, including a US-UK collaboration that's giving out interdisciplinary cancer grants to teams around the world. The studies are expected to release results this year and next.

2 ways to reduce your risk today

Until we know better what's going on, researchers and clinicians say there are two steps you can take to reduce colon cancer risk.

First, control what you can control.

"Let's focus on the stuff we can change," Dr. Cassandra Fritz, a gastroenterologist and colon cancer researcher at the Washington University School of Medicine in St. Louis, tells her patients.

That means no smoking, regular exercise, less alcohol, reducing your intake of ultra-processed snacks and processed meats, and no sugary beverages β€” factors directly linked with colon cancer risk. You could also consider microwaving food in glass or ceramic instead of plastic.

Second, know the signs of colon cancer and do not be complacent about them. Many young cases are diagnosed too late, making treatment complicated.

These four symptoms can occur up to 18 months before a colon cancer diagnosis:

  • Abnormal diarrhea that lasts for weeks
  • Persistent abdominal pain
  • Bloody stool (red, magenta, or black)
  • Iron deficiency anemia (determined by a blood test)

Don't fear the process of getting checked, experts told BI. Anyone dealing with these persistent symptoms can ask their doctor for a fecal immunochemical test (FIT) that is noninvasive and costs just a few dollars.

"If there are symptoms which could be associated with colon cancer, make sure you get the screening and don't just accept that they're saying 'It's unlikely' or 'I've never seen it,'" Lenz said.

When it's spotted early, colon cancer is a very survivable disease.

Why banning Red No. 3 in America took decades

Synthetic food dyes add a burst of color to many beloved American foods, such as candy, cereal, and even bacon. But some dyes β€” like Red No. 3 β€” have links to cancer, behavioral disorders, and other health issues.

Now, after more than 30 years, the FDA is banning Red No. 3 in cereals and other food products. The move comes as California is poised to ban synthetic dyes in schools, and as Robert F. Kennedy Jr. pushes for a nationwide ban on artificial dyes.

But how did synthetic dyes take over America's food system in the first place? And how will the FDA's new policy change how food giants formulate their products? Health editor Mia de Graaf breaks it down.

The FDA has banned Red No. 3, a synthetic dye used in candy, cereals, and Tylenol

  • Red No. 3 has been linked to cancer in some rat studies.
  • The FDA said food companies have until 2027 to strip the dye from products.
  • Regulators previously reviewed evidence linking food dye to ADHD.

The Food and Drug Administration has banned the use of a specific red dye that has been linked to cancer in some rat studies.

Red No. 3 is a synthetic dye which gives a cherry hue to candies, sodas, and some medications.

"The FDA cannot authorize a food additive or color additive if it has been found to cause cancer in human or animals," Jim Jones, the FDA's deputy director for human foods, said in a statement.

"Evidence shows cancer in laboratory male rats exposed to high levels of FD&C Red No. 3."

Food companies have until 2027 to phase out Red No. 3 from their products and replace them with natural dyes. Drug companies, like the maker of Tylenol PM, Johnson & Johnson, have until 2028.

Red No. 3 is present in a quarter of baking decorations and tenth of cookies sold in the US. Products include:

  • Nerds
  • Peeps
  • Morningstar Farms Veggie Bacon Strips
  • Vigo Saffron Yellow Rice
  • Tylenol PM

A spokesperson for the National Confectioners Association told Business Insider candy makers welcome more transparency and will reformulate products accordingly.

Is red food dye linked to cancer?

The move comes more than 30 years after the FDA banned the use of Red No. 3 in cosmetics, when animal studies showed links to cancer.

At the time, in 1990, the FDA promised to extend that ban to food products, too, because the Delaney Clause of 1958 says the FDA cannot condone any ingredients found to cause cancer in humans or animals.

That didn't happen, in part due to pressure from the food industry. "Americans like their cherries red," a food lobbyist who worked with the maraschino cherry industry told the Washington Post in 1989, fighting to keep Red No. 3.

Decades later, in 2022, 24 advocacy organizations came together to petition the FDA to ban Red No. 3, citing rat studies conducted in the 1980s that showed a link to thyroid cancer.

When the FDA revoked its authorization of Red No. 3 on January 15, the agency emphasized that it has no evidence of links to cancer in humans.

Food dye and ADHD

The ban is serendipitous timing for Robert F. Kennedy Jr., Trump's pick to lead the Health and Human Services Department, who has repeatedly stated that he believes artificial food dyes cause ADHD in children.

Kennedy has promised to ban all synthetic food dyes in his pursuit to "make America healthy again."

US and European regulators reviewed evidence linking synthetic food dyes to ADHD in 2011. While the EU determined the evidence was strong enough to warn against synthetic dyes for kids, the FDA said more research was needed.

Europe and California took the lead

In the EU, Red No. 3 is banned in all cosmetic and food products except cocktail cherries. Instead, manufacturers use natural dyes like carmine, turmeric, and beets to add vibrance to their products.

While US federal regulators have held off, California took action at the state level.

In 2023, Gov. Gavin Newsom signed a law banning Red No 3., giving food giants until 2027 to change their products. In late 2024, the state issued a ban on six other synthetic food dyes in public schools: Blue 1, Blue 2, Green 3, Red 40, Yellow 5, and Yellow 6. That, too, will take effect in 2027.

Consumer advocate organizations are calling on the FDA to follow California's lead and expand the ban to encompass all synthetic dyes.

"Many synthetic food dyes are allowed in food but haven't been reviewed for safety by the FDA in decades despite recent studies that have linked the chemicals to serious health problems," Brian Ronholm, director of food policy at Consumer Reports, said in a statement.

"It's time for the FDA to catch up with the latest science and get these harmful chemicals out of our food."

Wildfire smoke can cause chronic inflammation. Here are 6 ways to protect yourself.

  • Wildfires are burning across Los Angeles, coating the county in smoke.
  • Health agencies issued warnings and schools closed as air quality reached unsafe levels.
  • Experts break down why the fine-particle pollution can cause serious, long-term damage.

Wildfires erupted across Los Angeles, coating the county in smoke, haze, and an acrid smell.

The LA Public Health department issued an air quality alert, and many schools closed due to dangerous air quality. 

The mist that hovers over wildfire sites is a collection of fine-particle pollution (PM 2.5), Dr. David Hill, a pulmonologist with the American Lung Association, told the AP

"We have defenses in our upper airway to trap larger particles and prevent them from getting down into the lungs. These are sort of the right size to get past those defenses," Hill said. "When those particles get down into the respiratory space, they cause the body to have an inflammatory reaction to them."

What is the risk of wildfire smoke?

Fine-particle air pollution can cause inflammation in the lungs and reduce heart function β€” lasting effects similar to smoking cigarettes or exposure to diesel exhaust, the New York Times reported

Dr. Kari Nadeau, a physician and scientist at Stanford University, told the Times she believes the risk to our health is higher than that of smoking cigarettes. "Cigarettes at least have filters," Nadeau said.

This kind of air pollution is particularly risky for children, whose lungs are still developing. 

"They breathe in more air per unit of body weight," Laura Kate Bender, the lung association's National Assistant Vice President of healthy air, told the AP.

The risk of lung and heart irritation is also higher for older adults and people with lung or cardiovascular conditions, including asthma.

6 ways to stay safe when it's smoky outside

  • Keep an eye on the air quality in your area to determine how long you should exercise caution. Until the risk passes, there are easy things you can do to protect yourself from experiencing long-term lung inflammation.
  • If possible, stay inside and close your windows, Hill said. (You can put your zip code into AirNow.gov to find out the air quality in your area.)
  • Do not burn candles, light a fire, or smoke indoors. That increases indoor pollution, according to a blog post from epidemiologist Katelyn Jetelina, of the University of Texas Health Science Center.
  • Do not vacuum. That also affects your indoor air by kicking up any fine particles that may have come in through your window or door, Jetelina said.
  • If you do go outside, wear an N95 mask, which β€” if fitted correctly β€” blocks out 95% of particles larger than 0.3 microns. As such, they effectively keep out 2.5-micron particles, which we're seeing from the wildfire smoke. "N95 masks are the type of face covering protection that I would recommend for somebody who is outside during the air pollution caused by wildfires," Marina Vance, an assistant professor of mechanical engineering at the University of Colorado, Boulder, told Healthline.
  • While inside, you can run your air-conditioning unit if it has a good HVAC filter, and an air purifier can help too, the American Lung Association recommends.

The new science on alcohol and cancer: 4 studies that found a link

Researchers are finding that even moderate drinking carries health risks.

  • The US Surgeon General issued a report warning alcohol is associated with cancer.
  • He cited 4 recent studies to make his case that alcohol should have warning labels like cigarettes.
  • Some scientists disagree: Another major report, published in December, found alcohol has benefits.

Dr. Vivek Murthy, the U.S. Surgeon General, said Americans need to know there's a link between alcohol and cancer, citing four recent studies.

Murthy said all alcoholic beverages should have cancer warning labels on them, a measure Congress would have to design and approve.

In a new report, published January 3, Murthy outlined the research that persuaded him β€” and other medical professionals β€” that alcohol is a serious and under-appreciated health concern.

We want to hear from you about your drinking habits. If you're comfortable sharing with a reporter, please fill out this quick form. Note: We won't publish any part of your submission unless we contact you first.

Here's the data that backs up Murthy's advisory, with some caveats:

How alcohol causes cancer

There are four ways alcohol causes cancer, Murthy said, citing a 2021 Nutrients study.

The first two are widely accepted, he wrote. Most physicians agree that when alcohol breaks down in the body it can bind to DNA, damaging cells and fueling tumors. There is also robust evidence that alcohol can drive inflammation, which is linked to cancer.

The study points to newer research that suggests alcohol may influence hormones like estrogen, paving the way to breast cancer, though it's not exactly clear how.

Another emerging idea is that alcohol seems to provide a literal melting pot for other toxins. Tobacco, for example, dissolves in alcohol, which could make it easier for the body to ingest, the study says.

3 studies linking alcohol to cancer

To back up his argument for warning labels, Murthy pointed to a 2015 meta-analysis published in the British Journal of Cancer, which found "a significant relationship" between alcohol consumption and seven cancers.

The team of researchers from Italy, the US, France, Sweden, and Iran examined data from 572 studies, featuring 486,538 cancer cases. They compared the cancer risk of heavy drinkers with occasional drinkers and nondrinkers.

They found heavy drinking was linked to cancers of the mouth, throat, esophagus, colorectum, liver, larynx, and breast.

Murthy also referenced a 2020 study, published in Nature, that specifically looked at alcohol as a risk factor for head and neck cancer.

The research on around 40,000 people in 26 studies found higher-intensity drinking β€” consuming more drinks per day, and drinking more years in a lifetime β€” was correlated with higher risk of head and neck cancers.

The third significant study that Murthy highlighted was a 2018 global systematic analysis looking at alcohol-related deaths in 195 countries over the course of 26 years. That report, published in The Lancet, concluded that there is no safe level of alcohol consumption when it comes to cancer.

Each report has caveats. For example, the 2015 meta-analysis used varying measurements of alcohol and the 2018 study did not differentiate between drinking patterns, such as binge-drinking or moderate drinking.

Still, the studies are comprehensive, significant, and have informed many of the physicians who say that alcohol is a serious health concern.

Some scientists disagree

Murthy said he was motivated to publish this report because surveys suggest more than half of Americans do not recognize a link between alcohol and cancer.

The science on alcohol is not cut-and-dry, though.

Some of the healthiest people in the world β€” in the Mediterranean and so-called Blue Zones β€” drink wine daily. Researchers believe the social aspect of alcohol may have strong benefits for longevity.

Plus, Murthy's report clashes with a major report by the National Academies of Sciences, Engineering, and Medicine, which was published in December.

The paper, which will be used to inform the new 2025 Dietary Guidelines, found that moderate drinkers have a lower risk of premature death from heart attack and stroke than people who don't drink at all. It also found an increased risk in breast cancer.

The Department of Health and Human Services is due to publish its own analysis of the latest science on alcohol in the coming weeks.

Bernie Sanders wants to put warning labels on ultra-processed foods — with RFK Jr.'s MAHA movement as an unlikely ally

  • Bernie Sanders is taking on ultra-processed food in his final weeks leading the Senate health panel.
  • Sanders wants the US to catch up with other countries, which have cigarette-style warning labels for food.
  • He sees a potential opportunity to work with Robert F. Kennedy Jr. on this.

In his final weeks leading the Senate health committee, Sen. Bernie Sanders is taking on "big food."

Sanders led a hearing Thursday to interrogate how ultra-processed foods affect our bodies, and how they are regulated. He is campaigning for legislation that would slap warning labels on the front of ultra-processed foods β€” a step other countries took years ago.

Speaking to Business Insider on Tuesday, Sanders said he sees warning labels as a necessary first step to influence food manufacturers in America to make healthier products, especially for kids.

"When a parent goes out shopping, they need to know that there are products that are just not healthy for their kids," Sanders said. "In the United States, we have not reached that stage. Other countries are doing a lot better than we are."

Obesity has more than tripled among children since the 1970s, per CDC data, and research suggests ultraprocessed foods play a significant role, though it's not clear why. What we do know is that foods high in added sugars, fats, and sodium make up a majority of the calories we consume, and drive us to eat more.

"Our kids are not healthy enough," Sanders said.

Major food companies say new labels would be expensive to produce, and that the cost would be passed onto consumers. Some argue mandatory warning labels would violate their right to free speech. They say we should stick with the current system: a voluntary policy, where companies can put health warnings on the front of products if they see fit.

A shift may be coming, in part driven by Robert F. Kennedy Jr., Trump's pick for HHS secretary who has promised to "make America healthy again" and clean up the US food system. Kennedy's message has resonated with voters as consumer demand grows for healthier food β€” more natural, more transparent, less processed.

Food giants are nervous about Kennedy's reign, Jerold Mande, CEO of the advocacy group Nourish Science and a senior member of the USDA during the Obama administration, told Business Insider.

"Having worked on this for decades, the level of response from companies has exceeded anything I've seen" since Michelle Obama's campaign, Mande said. "They're deeply concerned that this is going to be a change."

Sanders said he is ready to ride the MAHA wave, if that's what it will take to clean up American diets.

The pitch: Bring the US up to speed with other countries

Sixteen other countries have mandatory, front-of-package warning labels, including most of Latin America, plus Canada, Iran, Sri Lanka, and Singapore.

Sanders looks at the US's southern neighbor, Mexico, as inspiration. During our interview, he pulled up a photo of two bottles of Coca-Cola, one sold in the US and the other in Mexico. The Mexican bottle has big black octagonal boxes that say "excess sugars," "excess calories," and "caffeine warning, not recommended for children."

"That's kind of common sense," Sanders said. "I think if most parents knew that there were 10 or 15 teaspoons of sugar in this drink, I suspect many parents would say, 'Sorry, Joe, you can't have that.' It would put pressure on the industry to start producing healthier products."

The Coca Cola Company did not immediately respond to a request for comment. A spokesperson for the American Beverage Association said the industry has taken voluntary steps to curb sugar for kids, such as not advertising to children and removing full-calorie products from schools.

According to research conducted in these countries, it can work β€” if the front-of-package labeling is clear.

In Chile, which has similar black boxes to Mexico, people dramatically reduced the amount of sugar-, fat-, and sodium-heavy products they were buying after labels changed. Companies have also reformulated their products in the country to avoid a warning label, cutting sugar, fat, and sodium levels.

How the US can get this done remains a mystery, Katherine Miller, founder of nutrition advocacy group Table 81, told Business Insider.

"I mean, there are 20 different pieces of the federal government that regulate our eggs," Miller said. "How do we really think we're going to get front of the label, the front-of-the-package labeling in a short period of time that will align the scientific community, the food systems community, the health community, and corporations? That doesn't feel realistic."

The US is already testing out new food labels that flag bad ingredients

The Food and Drug Administration has designed two options for what these new labels could look like on the front of food and drinks.

One version would flag a product as "high in" sugar, sodium, or fat, if it exceeds 20% of the daily recommended limit. Another version would use a color-coded system to grade the levels of sugar, sodium, and fat in the product ("low" for under 5%, "high" for over 20%, "medium" for anything in between).

The agency has spent months testing both options in focus groups.

Sanders says it doesn't go far enough.

He proposed legislation that would force food companies to put a stop sign on anything ultra-processed or high-sugar, similar to cigarettes.

Sanders β€” who says he is "guilty as anybody else" when it comes to eating and snacking β€” begrudges how difficult it is to make healthy choices and how easy it is to accidentally ingest copious amounts of fat, sodium, or sugar.

"Some years ago, I was thirsty and I picked up a bottle of something, it was a juice, and I gulped it down as usual," Sanders recalled in the interview. "A little while later, my stomach, I really felt very queasy. I looked at the label and I saw the amount of sugar that was in it."

It was a lot higher than he expected from a quick glance at the bottle.

"The industry has done a very good job in selling us products that are cheap to produce, that make us unhealthy. And that's something Congress has got to deal with."

The problem: A game of whack-a-mole with food companies

The argument against front-of-package labeling, from a health perspective, is that it could delay more concrete action.

It could also lead to unexpected consequences, Mande said.

In the '90s, when he helped design the original Nutrition Facts panel, the goal was low fat. A flurry of new research had recently come out showing fat was linked to heart disease.

Food manufacturers complied, cutting fat from their products β€” but often swapped it for something else. Take Snackwell's, a now defunct diet cookie brand that offered the pleasure of a sweet treat without the consequences. Problem was, the brand replaced fat with refined carbohydrates.

"We didn't anticipate the harm it would cause," Mande said. Three decades later, health advocates are trying to cut refined carbs in food due to the increased risk of diabetes.

Sanders said front-of-package labeling is the best card we have to play right now.

"I think it's one thing that you've got to do," he said. "It would put pressure on the industry to start producing healthier products."

Next step: Teeing up RFK Jr.

The Senate hearing saw more bipartisan agreement than advocates expected.

"Not one Senator defended the food industry. Big food is in big tobacco territory," Mande said.

Still, it comes at an inflection point. FDA Commissioner Rob Califf is on his way out, and there's no knowing whether his nominated successor, Marty Makary, will want to follow through on his plans for front-of-package labels.

Plus, it's unclear if Makary will have the funds to do so, since Robert F. Kennedy Jr. says he will gut the FDA if he is confirmed as HHS Secretary. (Kennedy did not respond to a request for a comment.)

Sanders hopes this discussion will harness the buzz around Kennedy's MAHA movement to make warning labels a policy priority.

"When Kennedy talks about an unhealthy society, he's right. The amount of chronic illness that we have is just extraordinary," Sanders said.

"Anybody with a brain in his or her head wants to deal with this issue, to get to the cause of the problem. I think processed food and the kind of sugar and salt that we have in products that our kids and adults are ingesting is an important part of addressing that crisis."

Bernie Sanders says Elon Musk is 'a very smart guy' and RFK Jr. 'is right' about our unhealthy society

  • Sen. Bernie Sanders told Business Insider he's reaching across the aisle to find common ground.
  • He has no qualms about working with Elon Musk on any good ideas he has about spending.
  • Sanders also cited areas of mutual interest with RFK Jr. on health and Trump on credit-card debt.

Sen. Bernie Sanders is extending an olive branch to President-elect Donald Trump and his incoming administration.

In an interview with Business Insider on Tuesday, the Vermont senator listed areas of common ground with Elon Musk, a cochair of a new extragovernmental body aiming to cut costs, as well as with Robert F. Kennedy Jr. on health and Trump on credit debt.

"If somebody on the other side has a good idea, sure, I'll work with them," Sanders, who at 83 is the longest-serving independent in Congress, told BI.

In Musk, Sanders may find an ally to cut defense spending

Sanders made headlines on Sunday when he posted on X his support for Musk's pitch to curb defense spending.

Musk, whom Sanders has previously criticized as a threat to democracy, responded with a laughing emoji and said, "Maybe we can find some common ground."

Sanders told BI he had no qualms about working with Musk on the Department of Defense's spending, or on any other good ideas he has as cochair of DOGE, the new Department of Government Efficiency announced by Trump.

"Many of the things he did during the campaign were really ugly. On the other hand, he's a very smart guy," Sanders said, adding that "he is absolutely right" to call for the first independent audit of the Pentagon in over seven years.

"We need a strong military, but we don't need all the waste and the profiteering and the fraud that exists in the Pentagon right now," he said.

While Musk has yet to outline specific plans to curb defense spending, he has criticized the Department of Defense's F-35 program and cited its $841 billion budget in a Wall Street Journal op-ed about his mission to cut costs. In April, Sanders pushed to cut $88.6 billion, or 10%, from the military budget.

The amendment was outvoted, and Sanders slammed lawmakers, saying they're pouring money into an unaudited department.

In 2021, the Pentagon said that it was trying to learn from each failed audit but that it would take until 2028 to make all the logistical changes necessary to meet standards.

The Department of Defense did not immediately respond to a request for comment.

Finding connection through Kennedy's MAHA movement

Sanders, a cochair of the Senate health committee, told BI he also saw common ground with Kennedy, particularly when it comes to ultraprocessed food.

Kennedy, Trump's pick to lead the Department of Health and Human Services, faces a tough confirmation hearing, given his opposition to vaccines and plans to take on food giants and industry lobbyists.

If confirmed, he has pledged to "make America healthy again" by tackling chronic disease. He promises to ban processed foods from school meals and remove food dyes from the US food system, among other measures.

Sanders is game for a shake-up of our nutrition system. This week, he's leading a Senate hearing on ultraprocessed foods, interrogating how processed products are regulated and how they affect health.

"When Kennedy talks about an unhealthy society, he's right. The amount of chronic illness that we have is just extraordinary," Sanders told BI.

He cited the millions of people living with obesity and diabetes and the ripple effects across all sectors. Diabetes care now costs the US an estimated $400 billion a year, a GlobalData analysis found. And a recent report said the military was struggling to recruit young people who meet the physical requirements to be enlisted.

"Our kids are not healthy enough. In the long run, you want a healthy society as an end in itself," Sanders said. "We want our people to have long lives, productive lives, happy lives. That's what we want. And if the industry is giving our kids food that's making them overweight, leading to diabetes and other illnesses, clearly that's an issue that we've got to deal with."

Sanders, who has previously criticized Kennedy's views on vaccines, added: "I think a lot of what RFK is saying is kind of crazy and driven by conspiracy theory. Some of what he's saying is not crazy.

"Anybody with a brain in his or her head wants to deal with this issue, to get to the cause of the problem. I think processed food and the kind of sugar and salt that we have in products that our kids and adults are ingesting is an important part of addressing that crisis."

Kennedy did not immediately respond to a request for comment.

Sanders wants Trump to stick to his proposed cap on credit-card interest rates

While Trump and Sanders are on opposite sides of the political spectrum, they may have common ground on credit-card interest rates.

Credit-card debt held by American consumers hit $1.17 trillion in 2023, according to the Federal Reserve Bank of New York.

"Donald Trump came out with an idea during this campaign. He said, you know what, credit-card interest rates, which in some cases right now are 20, 25%, should not be higher than 10%. Well, you know what? I agree with that," Sanders said.

While Trump said a cap would be "temporary" to help Americans "catch up" with payments, the suggestion made a splash. Mark Cuban, a longtime critic of Trump, mocked him for going even further than "self-described socialist Bernie Sanders."

It would be tough to drive through Congress, as Sanders knows. He and Rep. Alexandria Ocasio-Cortez tabled an interest-rate cap of 15% in 2019, which went nowhere.

Now Sanders is challenging Trump to wield his strong mandate to make this a key issue.

"We'll see if Mr. Trump is prepared to keep his word. We're looking forward, and we will work with some Republicans on that issue," Sanders said.

Trump did not immediately respond to a request for comment.

"Where Trump and Republicans make sense, happy to work with them," Sanders said. "And we will be in vigorous opposition to many of their policies, which to me are extremely distasteful."
