The ongoing federal shutdown has resulted in a pause on regular government data releases, meaning economic data has been in short supply of late. That has left market-watchers and monetary policymakers somewhat in the dark over key indicators in the U.S. economy.

Fortunately, the University of Michigan’s Surveys of Consumers is unaffected by the impasse in Washington and released its preliminary monthly report on Oct. 10, 2025; the final read of the month will be released in two weeks.

The Conversation U.S. spoke with Joanne Hsu, the director of the Surveys of Consumers, on what the latest data shows about consumer sentiment – and whether the shutdown has left Americans feeling blue.

What is consumer sentiment?

Consumer sentiment is something that we at the University of Michigan have measured since 1946. It looks at American attitudes toward the current state of the economy and the future direction of the economy through questions on personal finances, business conditions and buying conditions for big-ticket items.

Over the decades, it has been closely followed by policymakers, business leaders, academic researchers and investors as a leading indicator of the overall state of the economy.

When sentiment is on the decline, consumers tend to pull back on spending – and that can lead to a slowdown in the economy. The opposite is also true: High or rising sentiment tends to lead to increased spending and a growing economy.

How is the survey compiled?

Every month, we interview a random sample of the U.S. population across the 48 contiguous states and the District of Columbia. Around 1,000 or so people take part in it every month, and we include a representative sample across ages, income, education level, demography and geography. People from across all walks of life are asked around 50 questions pertaining to the economy, personal finances, job prospects, inflation expectations and the like.

When you aggregate that all together, it gives a useful measure of the health of the U.S. economy.

What does the latest survey show?

The latest survey shows virtually no change in overall sentiment between September and October. Consumers are not feeling that optimistic at the moment, but generally no worse than they were last month.

Pocketbook issues – high prices of goods, inflation and possible weakening in the labor market – are suppressing sentiment. Views of consumers across the country converged earlier in the year when the Trump administration’s tariffs were announced. But since then, higher-wealth and higher-income consumers have reported improved consumer sentiment. It is for lower-income Americans – those not owning stock – that sentiment hasn’t lifted since April.

In October, we also saw a slight decline in inflation expectations, but it remains relatively high – midway between where they were around a year ago and the highs of around the time of the tariff announcements in April and May.

Has the government shutdown affected consumer sentiment?

The government shutdown was in place for around half the time of the latest survey period, which ran from Sept. 23-Oct. 6, 2025. And so far, we are not seeing evidence that it is impacting consumer sentiment one way or another.

And that is not super-surprising. It is not that people don’t care about the shutdown, just that it hasn’t affected how they see the economy and their personal finances yet.

History shows that federal shutdowns do move the needle a little. In 2019, around 10% of people spontaneously mentioned the then-shutdown in the January survey. We saw a decline in sentiment in that month, but it did improve again the following month.

Looking back, we tend to see stronger reaction to shutdowns when there is a debt ceiling crisis attached. In 2013, for example, there was a decline in consumer sentiment coinciding with concerns over the debt ceiling being breached. But it did quickly rebound when the government opened again.

Whether or not we see a decline in sentiment because of the current shutdown depends on how long it lasts – and how consumers believe it will impact pocketbook issues, namely prices and job prospects.

With the indictment on Oct. 9, 2025, of New York Attorney General – and longtime Donald Trump adversary – Letitia James on two criminal counts related to loans for a home purchase, mortgage fraud is back in the news.

Lisa Cook, a Federal Reserve governor, is also being investigated by the Department of Justice for allegedly making false statements when applying for a mortgage. Members of Donald Trump’s Cabinet are accused of similar wrongdoings. Could any of these people go to prison?

Mortgage fraud is not a new problem. Subprime mortgage fraud fueled the 2008 financial meltdown, when large numbers of very risky mortgages defaulted. Mortgage fraud was also a key feature of the savings and loan crisis in the 1980s.

Mortgage applications are very long, so there’s plenty of opportunity to make mistakes. Plus, they require borrowers to declare that everything is “true, accurate, and complete.” Misrepresentation can trigger potentially large civil and criminal penalties.

As a business school professor, I was curious how many people are convicted of mortgage fraud today. After all, relatively few people went to jail for fraudulent loans back in 2008. Since most mortgage fraud violates federal law, I looked at more than a decade of federal conviction data. What I found was clear: Almost no one has gone to federal prison recently for lying on a mortgage application.

What is mortgage fraud?

Mortgage fraud is when someone intentionally misrepresents facts in order to obtain a property loan. People can lie about many things on a mortgage application, such as their income, assets or employment status, or whether they will occupy the home being purchased or rent it out.

Being caught lying to get a mortgage can be costly. The maximum federal sentence is 30 years, with fines of up to US$1 million. Because more than a quarter of all mortgages are guaranteed by federal agencies, and many are acquired by quasi-government organizations like Freddie Mac and Fannie Mae, most mortgage fraud is a federal crime.

However, just because there are laws on the books doesn’t mean they’re enforced. For example, I work in Boston, where for years jaywalking has been illegal – but as any visitor quickly notices, no one pays any attention to this rule.

How many people are convicted?

The U.S. Sentencing Commission provides detailed data on every person convicted of federal crimes since 2013. The database is large, since federal courts convict almost 70,000 people each year.

However, very few people are convicted of federal mortgage fraud. Just 38 people in the country were sentenced for such crimes in 2024, and among that small group, four of the convicted got no prison time. A year earlier, just 34 people were convicted and seven avoided prison.

Over the past dozen years, fewer than 3,000 people were convicted of federal mortgage fraud, and the number of people sentenced fell steadily each year.

Three thousand people are a tiny fraction of mortgages issued. The Consumer Financial Protection Bureau estimates that almost 100 million new mortgage loans were written to purchase or refinance a home over the past 12 years. For those who like precision, 3,000 is only 0.003%.

The Sentencing Commission’s files also offer insight into who gets convicted of mortgage fraud. Three-quarters were men. More than 90% were U.S. citizens. The typical person convicted of mortgage fraud is a man in his late 40s with an associate degree, the data suggests.

The real penalty

While the maximum penalty is 30 years, almost no one serves that long a sentence. In 2024, the maximum sentence handed out was just 10 years. Since 2013, 15% of those convicted got no jail time. The average sentence for people who did get jail time was 21 months, which is less than two years behind bars.

Fines are also much lighter in practice than the maximum $1 million penalty. In 2024, the maximum fine passed down was a quarter-million dollars. Since 2013, the average person convicted of mortgage fraud paid a fine of less than $6,000, with over half of all those convicted paying no fine at all.

Now not paying a fine or only paying a small one doesn’t mean there’s no financial penalty. The courts required most of those convicted to make restitution. In 2024, half of all people convicted had to pay at least a half-million dollars to reimburse their victims, such as lending companies. Over the dozen years I looked at, the average person convicted paid $2 million in restitution for their misdeeds.

More lightning strikes than convictions

It’s impossible to know how common mortgage fraud really is. Some mortgage applications are rechecked in a “post-closing audit.” However, these audits happen within 90 days after the mortgage money is disbursed. Beyond that window, if a loan is paid back on time and without problems, there’s little incentive for a bank or mortgage service provider to recheck an applicant’s information.

What is clear is that while millions of mortgages are written each year, only a tiny fraction of mortgage recipients go to jail for fraud. One way to put this tiny fraction into perspective is to compare it with the National Weather Service estimates of the approximately 270 people hit by lightning yearly. Last year, lightning hit over seven times more people than the federal government convicted of mortgage fraud.

Years ago, I filled in a mortgage application to buy a home. I was consumed with dread wondering if any application mistake would result in my being sent to jail. After looking at the mortgage fraud conviction data, I should have been more worried about being hit by lightning.

Like many star-crossed lovers, Elaine Goodale and Charles Alexander Eastman came from different worlds.

Goodale, born in 1863 to a family claiming Puritan roots, grew up on a farm in a remote part of western Massachusetts. In 1858, a baby first named Hakadah, later called Ohíye S’a, who then became widely known as Charles Alexander Eastman for most of his adult life, was born near Redwood Falls, Minnesota. A Wahpeton Santee Dakota, he fled to Manitoba, Canada, with tribal members during the 1862 Dakota War between the U.S. military and several bands of Dakota collectively known as the Santee Sioux.

In December 1890, the two unexpectedly met each other while working at the Pine Ridge Agency in the newly declared state of South Dakota. Even more improbably, they fell in love.

Just weeks later, booming Hotchkiss rifles 15 miles away signaled the start of the Wounded Knee Massacre. Federal troops ended up killing at least 250 Lakota Sioux men, women and children; the traumatic event, historian David Martínez writes, sparked “the abrupt transformation of Indian nations from geopolitical powers … to symbols of conquest.”

It also transformed Goodale and Eastman’s nascent relationship: They resolved to marry and to work together for Native American causes.

Wounded Knee, however, would also prove an unfortunate metaphor for their marriage.

In the research for my new dual biography, “Love and Loss After Wounded Knee: A Biography of an Extraordinary Interracial Marriage,” I dove into letters, photographs and hundreds of newspaper articles documenting this high-profile, late-19th-century relationship.

I came to understand that their marriage failed not only because of interpersonal tensions and a clash of values, but also because of some of the ways in which ideas about gender, race and Indigenous identity were rapidly changing in the U.S.

From writer to teacher

At 13, Goodale started publishing poetry in St. Nicholas Magazine, a popular children’s periodical. Her poems generated attention from the press, in addition to fan mail from notable men of letters, including Henry Wadsworth Longfellow. By the time she was 20, she had published five books.

But because poets without family fortunes needed other means to support themselves – and because women in the late 1800s had few career options – Goodale turned to teaching. She accepted a job at Virginia’s Hampton Institute, a boarding school that was founded to teach newly emancipated Black students. It later became part of the government’s program to assimilate Native Americans.

Goodale became convinced that Indigenous children would benefit more from schools in their own communities, rather than at government- or church-run boarding schools. She traveled to the Dakota Territory and opened a day school. She also turned from poetry to prose, documenting her observations of “Indian life and education” in dozens of articles.

By the time she came to Pine Ridge Agency, the administrative offices at the Oglala Lakota Indian Reservation, she had been appointed the first supervisor of education for the Dakotas.

The ideal ‘assimilated Indian’

Ohíye S’a’s early years were marked by family trauma and U.S. government policies aimed at seizing land and displacing and assimilating Native people. His mother died shortly after he was born, and during the Dakota War it was widely believed that his father and brothers had perished. His grandmother and uncle raised him until his mid-teenage years.

In 1873, the 15-year-old was surprised to discover that his father was, in fact, alive. Jacob Eastman had taken a European-American name and converted to Christianity. He was convinced that only a formal English-language education could provide a path forward for Native people.

At his father’s urging, Ohíye S’a became “Charles Eastman,” and he also converted to Christianity. He attended a series of boarding schools before landing at Dartmouth College and then Boston University Medical School.

His white mentors saw Eastman – the only Native person in his class at either institution – as the ideal “assimilated Indian.” His achievements often appeared in newspapers with headlines like “He’s a Winner: Sioux Indian Who Got a Boston University Degree,” an allusion to the fact that “Ohíye S’a” translated to “winner.”

It isn’t clear whether Eastman ever thought of himself in that way. But throughout his life, he straddled the world in which he was raised and the one in which he was educated. His first job, as agency physician at Pine Ridge, placed him at the nexus of these two cultures.

An unlikely pair, a media sensation

After the shots rang out near Wounded Knee Creek, Eastman’s medical education was put to the test. Called into service as a nurse, Goodale also tended the wounded and dying in the makeshift hospital at a nearby church.

Six months later, Elaine and Charles were married in New York City in June 1891, much to the consternation of her family.

The couple’s nuptials appeared in hundreds of newspapers, partially due to the rarity of an interracial marriage in the 19th century. Much of the coverage was rife with racist stereotypes.

The Watertown Times in New York proclaimed, “Poetess Marries a Big Injun’”; the San Francisco Examiner ran a front-page story declaring “Fair Bride of An Indian: Elaine Goodale Weds the Red Man of Her Choice.”

Sometimes, articles focused on Charles’ educational background, often misrepresenting it by suggesting he had attended Cornell, Harvard or Yale. He was referred to as a “specimen,” with racialized language discussing his physical attributes: “He is of medium height … with all the peculiarities of his people in his features. His eyes are small and glittering, his face and nose are broad and his cheek bones very pronounced,” according to the San Francisco Examiner.

This type of media coverage – highlighting the differences between Elaine and Charles’ backgrounds, while pointedly describing Charles in stereotyped ways – would dog them throughout their marriage.

Professional travails, personal problems

Charles attempted to set up his own medical practice in St. Paul, Minnesota. But white patients proved reluctant to see “an Indian doctor,” while Native patients were hesitant to patronize a physician dispensing unfamiliar medicines. The practice failed.

Financial pressures increased over the next decade as Elaine and Charles became parents of six children. They moved frequently: Charles took on a series of jobs, including recruiting for the YMCA, lobbying on behalf of the Santee Sioux, and working as an “outing agent” at the Carlisle Indian Industrial School, which involved finding summer placements for Native students with white families in a further attempt to Americanize them.

Because Charles left behind few personal papers, it’s difficult to know if he believed in this program. But it’s easy to see how it could have created an identity crisis of sorts.

At other points in his life, Charles seemed to put his Dakota identity front and center. For example, he was one of the co-founders of the Society of American Indians, an organization that worked on behalf of self-determination for Native Americans. He even served as its president in 1918. Meanwhile, his wife remained a staunch believer in assimilation.

At Elaine’s urging – and likely, under her editorial stewardship – Charles began publishing stories and then books about his “Indian Boyhood.” While Elaine continued writing and was able to publish a few books, his literary career took off and hers stalled out.

Even their children weren’t spared from the headlines. An article in the St. Paul Globe wrote, of one of the Eastman children, “… the child had not inherited any of the attractiveness of the mother. It was a veritable old squaw miniature.”

In her personal writing, Elaine never acknowledged her children as biracial. The public stereotyping and private dismissal of the Eastman children’s identities were undoubtedly another stressor in an already-stressed marriage.

Pictures worth a thousand words

After many moves, the Eastmans landed in Amherst, Massachusetts. But Charles did not stay put, embarking upon a vigorous new career on the lecture circuit.

He became one of the best-known Native Americans of his era, as well as one of the most photographed.

Sometimes Charles chose to appear in a Victorian suit and cravat. Other times he posed in traditional Sioux regalia. Often the coverage of his talks focused more on what he was wearing than the content of his lecture. Historian Kiara Vigil suggests that Charles knew that his dress functioned as an advertisement for his work, arguing that his choice of attire was strategic: “Eastman’s ability to dress up as an Indian, or not, enabled him to address diverse audiences and their expectations.”

He was away from home more than he was present, further fueling Elaine’s resentment. In personal letters, she described her bitterness at Charles leaving the children and household to her sole care, and her belief that he was reinforcing the gender roles she’d railed against. While she certainly understood that his posing in buckskin and feathered headdress was good marketing, she probably never realized what reclaiming his Indigenous identity meant to Charles; she, too, thought of him as the product of successful assimilation.

It all falls apart

The personal and professional pressures on the Eastmans continued through the early years of the 20th century.

They reached a breaking point after their second daughter, Irene Taluta, died in the 1918 influenza pandemic. The tragic loss of a beloved child continued to unravel an already frayed marriage.

Elaine and Charles separated in 1921, though they never formally divorced.

I’ve been interested in the Eastmans and their unlikely marriage since I first learned of it years ago. As I pieced together parts of this complex relationship, I became convinced that while their compelling story reveals much about late 19th and early 20th century America, it’s also a story for today.

At a time of profoundly unsettling controversies around race, immigration and identity, the marriage of Elaine Goodale and Charles Eastman underscores why it can be so challenging for people from different backgrounds to truly understand each other.

But their story – how their mutual commitment to improve life for Native American people brought them together, how their quest to educate the nation about a marginalized people gave them purpose, and the ways in which they melded the personal and the political – also suggests the importance of trying.

The Trump administration is trying to eliminate diversity, equity and inclusion programs as part of a broader campaign to end what it calls “wokeness” in American education.

As part of this rollback, the Justice Department announced in July 2025 that it would no longer “defend” the federal definition of Hispanic-Serving Institutions, or HSIs. These are colleges where at least 25% of undergraduates identify as Hispanic or Latino.

This is more than a legal technicality. It reflects the Justice Department’s position that HSI grants violate constitutional protections, putting millions of federal dollars for these schools at risk.

Citing this legal rationale, the Department of Education confirmed in September that it had frozen US$350 million in education grants intended for Minority-Serving Institutions. This includes more than $250 million for HSIs, specifically.

The Education Department argues that these programs amount to racial discrimination because they tie federal grants to students’ racial or ethnic backgrounds.

This echoes the Supreme Court’s decision in 2023, which narrowed how colleges can consider race and ethnicity in admissions.

I serve as the university diversity officer at California State University, Chico, an HSI. I am also an ethnic studies scholar who focuses on equity in higher education.

Advocates for HSIs say ending federal funding would hurt already underfunded colleges, particularly those that serve large numbers of first-generation and low-income students.

What are Hispanic-Serving Institutions?

Congress created the HSI designation in 1992, through an amendment to the 1965 Higher Education Act. This amendment authorizes federal grants to help strengthen colleges that enroll large numbers of Hispanic and low-income students, providing more opportunity for those students to succeed and graduate.

There are more than 600 federally designated HSIs across the U.S. and Puerto Rico. California is home to the most HSIs, with 167, followed by Texas, Puerto Rico, New York and Illinois.

In addition to showing that at least 25% of its student population is Hispanic or Latino, any college or university that wants to qualify as an HSI must also show that at least half of its students come from low-income backgrounds.

Becoming an HSI allows colleges and universities to apply for federal funding intended to support underrepresented and low-income students.

HSIs vary in size and mission

HSIs enroll over 1.5 million Hispanic students, which amounts to over 60% of all Hispanic undergraduates in the U.S.

This marks a big increase from the 340,000 Hispanic undergraduates who attended an HSI in 1995.

Some of these schools are large public research universities, such as University of California, Riverside; University of California, Santa Barbara; and University of California, Santa Cruz. Others are regional institutions, private colleges and local community colleges.

Over the past decade, another kind of Hispanic-Serving Institution has emerged – research-intensive HSIs. These are colleges and universities where at least 25% of the student body is Hispanic and where there is significant research funding and a range of doctoral programs offered. These schools include University of California, Irvine; Florida International University; and the University of Texas at El Paso, among others.

Some researchers have debated whether the HSI category has become too broad, grouping schools with vastly different resources, missions and student populations.

Despite their differences, many HSIs enroll large numbers of first-generation, low-income and working students, as well as immigrants and transfer students.

HSIs also generally operate with fewer financial and academic resources than comparable non-HSI institutions.

How HSI funding works

Title V grants from the Department of Education are one clear way that HSIs can receive federal funding .

These competitive grants are intended to help HSIs expand educational opportunities and institutional capacity to support Hispanic and low-income students.

Rather than providing aid directly to students, Title V grants are used to offer faculty training, update classrooms and laboratories, create new degree programs and develop mentorship opportunities for first-generation students.

At campuses such as California State University, Chico and University of California, Irvine, Title V grants have given schools the money to create bilingual advising services and maintain data systems.

Title V grants form only one part of the broader funding picture for HSIs. Like many colleges, HSIs rely on state funding and tuition revenue. They also compete for other federal grants, including those from the National Science Foundation and the Department of Agriculture.

How HSIs help Hispanic students

A growing body of research shows that HSIs are crucial in helping more Hispanic and first-generation students attend and graduate college.

Some HSIs have received national recognition for using evidence-based practices to help Hispanic students perform better in the classroom. Hispanic students at these schools, which include Arizona State University and California State University, Fullerton, graduate at rates roughly 8 percentage points higher than Hispanic students nationally.

Hispanic students at HSIs graduate at rates more than 5 percentage points higher than those at comparable non-HSI colleges, according to similar 2017 findings from the nonprofit Education Trust.

There are a few reasons why there is a relatively high graduation rate for Hispanic students at HSIs.

Students at HSIs often report feeling a strong sense of belonging and see their own cultures reflected in the curriculum. Many HSI campuses also offer dedicated programs for first-generation students and train faculty to teach and advise with equity and inclusion in mind.

At University of California, Irvine, where I helped lead HSI initiatives, Hispanic undergraduate enrollment grew by nearly 150% between 2009 and 2019, from 3,000 students to more than 7,500.

During that time, more than 350 faculty and staff completed equity-focused training to strengthen advising and teaching practices that support Hispanic and other underrepresented students.

What’s at stake for HSIs

Hispanic Americans now make up nearly 20% of the U.S. population, and their college enrollment numbers are projected to grow from about 3.7 million in 2020 to 4.5 million by 2030, as overall college enrollment numbers are projected to decline during this time.

A national evaluation of Title V projects found that most colleges and universities used these grants to improve student services, develop new academic programs and build community partnerships that help first-generation and low-income students stay enrolled and complete their degrees.

As HSI researchers note, graduation rates tell only part of the story. True student success at HSIs depends not just on graduation numbers, but on culturally responsive teaching, inclusive campus climates and equity-minded institutional practices.

How policymakers define and fund HSIs will shape not only the future of these institutions but also whether this growing generation of Hispanic students can access, afford and complete college in the years ahead.

Joseph Morales, Ph.D., works at California State University, Chico, a federally designated Hispanic-Serving Institution (HSI). While not a principal investigator on any federal HSI grants, he has participated in professional development programs and national conferences hosted by organizations mentioned in the article, including the Hispanic Association of Colleges and Universities (HACU). These experiences inform his understanding of the field but did not influence the content of this piece.

People often joke that their favorite snack is “like crack” or call themselves “chocoholics” in jest.

But can someone really be addicted to food in the same way they could be hooked on substances such as alcohol or nicotine?

As an addiction psychiatrist and researcher with experience in treating eating disorders and obesity, I have been following the research in this field for the past few decades. I have written a textbook on food addiction, obesity and overeating disorders, and, more recently, a self-help book for people who have intense cravings and obsessions for some foods.

While there is still some debate among psychologists and scientists, a consensus is emerging that food addiction is a real phenomenon. Hundreds of studies have confirmed that certain foods – often those that are high in sugar and ultraprocessed – affect the brains and behavior of certain people similarly to other addictive substances such as nicotine.

Still, many questions remain about which foods are addictive, which people are most susceptible to this addiction and why. There are also questions as to how this condition compares to other substance addictions and whether the same treatments could work for patients struggling with any kind of addiction.

How does addiction work?

The neurobiological mechanisms of addiction have been mapped out through decades of laboratory-based research using neuroimaging and cognitive neuroscience approaches.

Studies show that preexisting genetic and environmental factors set the stage for developing an addiction. Regularly consuming an addictive substance then causes a rewiring of several important brain systems, leading the person to crave more and more of it.

This rewiring takes place in three key brain networks that correspond to key functional domains, often referred to as the reward system, the stress response system and the system in charge of executive control.

First, using an addictive substance causes the release of a chemical messenger called dopamine in the reward network, which makes the user feel good. Dopamine release also facilitates a neurobiological process called conditioning, which is basically a neural learning process that gives rise to habit formation.

As a result of the conditioning process, sensory cues associated with the substance start to have increasing influence over decision-making and behavior, often leading to a craving. For instance, because of conditioning, the sight of a needle can drive a person to set aside their commitment to quit using an injectable drug and return to it.

Second, continued use of an addictive substance over time affects the brain’s emotional or stress response network. The user’s body and mind build up a tolerance, meaning they need increasing amounts of the substance to feel its effect. The neurochemicals involved in this process are different than those mediating habit formation and include a chemical messenger called noradrenaline and internally produced opioids such as endorphins. If they quit using the substance, they experience symptoms of withdrawal, which can range from irritability and nausea to paranoia and seizures.

At that point, negative reinforcement kicks in. This is the process by which a person keeps going back to a substance because they’ve learned that using the substance doesn’t just feel good, but it also relieves negative emotions. During withdrawal from a substance, people feel profound emotional discomfort, including sadness and irritability. Negative reinforcement is why someone who is trying to quit smoking, for instance, will be at highest risk of relapse in the week just after stopping and during times of stress, because in the past they’d normally turn to cigarettes for relief.

Third, overuse of most addictive substances progressively damages the brain’s executive control network, the prefrontal cortex, and other key parts of the brain involved in impulse control and self-regulation. Over time, the damage to these areas makes it more and more difficult for the user to control their behavior around these substances. This is why it is so hard for long-term users of many addictive substances to quit.

What evidence is there that food is addictive?

Many studies over the past 25 years have shown that high-sugar and other highly pleasurable foods – often foods that are ultraprocessed – act on these brain networks in ways that are similar to other addictive substances. The resulting changes in the brain fuel further craving for and overuse of the substance – in this case, highly rewarding food.

Clinical studies have demonstrated that people with an addictive relationship to food demonstrate the hallmark signs of a substance use disorder.

Studies also indicate that for some people, cravings for highly palatable foods go well beyond just a normal hankering for a snack and are, in fact, signs of addictive behavior. One study found that cues associated with highly pleasurable foods activate the reward centers in the brain, and the degree of activation predicts weight gain. In other words, the more power the food cue has to capture a person’s attention, the more likely they are to succumb to cravings for it.

Multiple studies have also found that suddenly ending a diet that’s high in sugar can cause withdrawal, similar to when people quit opioids or nicotine.

Excessive exposure to high-sugar foods has also been found to reduce cognitive function and cause damage to the prefrontal cortex and hippocampus, the parts of the brain that mediate executive control and memory.

In another study, when obese people were exposed to food and told to resist their craving for it by ignoring it or thinking about something else, their prefrontal cortexes were more active compared with nonobese individuals. This indicates that it was more difficult for the obese group to fight their cravings.

Finding safe treatments for patients struggling with food

Addiction recovery is often centered on the idea that the fastest way to get well is to abstain from the problem substance. But unlike nicotine or narcotics, food is something that all people need to survive, so quitting cold turkey isn’t an option.

In addition, eating disorders such as bulimia nervosa and binge-eating disorder often occur alongside addictive eating. Most psychologists and psychiatrists believe these illnesses have their root cause in excessive dietary restriction.

For this reason, many eating disorder treatment professionals balk at the idea of labeling some foods as addictive. They are concerned that encouraging abstinence from particular foods could trigger binge eating and extreme dieting to compensate.

A way forward

But others argue that, with care, integrating food addiction approaches into eating disorders treatment is feasible and could be lifesaving for some.

The emerging consensus around this link is moving researchers and those who treat eating disorders to consider food addiction in their treatment models.

One such approach might look like the one described to me by addiction psychiatrist and eating disorders specialist Dr. Kim Dennis. In line with traditional eating disorder treatment, nutritionists at her residential clinic strongly discourage their patients from restricting calories. At the same time, in line with traditional addiction treatment, they help their patients to consider significantly reducing or completely abstaining from particular foods to which they have developed an addictive relationship.

Additional clinical studies are already being carried out. But going forward, more studies are needed to help clinicians find the most effective treatments for people with an addictive relationship with food.

Efforts are underway by groups of psychologists, psychiatrists, neuroscientists and mental health providers to get “ultraprocessed food use disorder,” also known as food addiction, into future editions of diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders and the World Health Organization’s International Classification of Diseases.

Beyond acknowledging what those treating food addiction are already seeing in the field, this would help researchers get funding for additional studies of treating food addiction. With more information about what treatments will work best for whom, those who have these problems will no longer have to suffer in silence, and providers will be better equipped to help them.

I have two books for sale which address food addiction, and I could benefit financially from increased interest in the food addiction topic:

Wilcox C.E. Food Addiction Obesity and Disorders of Overeating: An Evidenced Based Assessment and Clinical Guide. (2021) Springer

Wilcox C. Rewire Your Food-Addicted Brain: Fight Cravings and Break Free from a High-Sugar Ultra-Processed Diet. (2025) New Harbinger Publications
