The Ultra-Processed Foods Adding Most Calories to US Diet

Americans consume more than half their calories from ultra-processed food with burgers, sandwiches, sweet bakery products and savory snacks among the biggest contributors, according to a new federal report.
The study from the U.S. Centers for Disease Control and Prevention (CDC) found that Americans aged one year and older got an average of 55 percent of their daily intake from such food.
While nutrition research has shown for years that ultra-processed foods make up a big chunk of the US diet, the CDC has for the first time confirmed those high levels of consumption, using dietary data collected from August 2021 to August 2023.
Why it Matters
The new CDC report used the most common definition of ultra-processed foods. based on the four-tier Nova system that classifies foods according to the amount of processing they undergo. Such foods tend to be "hyperpalatable, energy-dense, low in dietary fiber and contain little or no whole foods, while having high amounts of salt, sweeteners and unhealthy fats," the CDC report said.

Centers for Disease Control and Prevention
Previous studies have linked ultra-processed food to obesity, diabetes and heart disease, but they haven't been able to prove that the foods directly cause those chronic health problems. One small but influential study found that even when diets were matched for calories, sugar, fat, fiber and micronutrients, people consumed more calories and gained more weight when they ate ultra-processed foods than when they ate minimally processed foods.
While the CDC report noted a modest decline in consumption among adults (from 55.8 percent to 53 percent) and youth (from 65.6 percent to 61.9 percent) over the past decade, health officials caution that these foods remain a dominant source of calories in the American diet.
The report has been published amid growing scrutiny of such foods with Health Secretary Robert F. Kennedy Jr telling Fox earlier this year, "We are poisoning ourselves, and it's coming principally from these ultra-processed foods."
What To Know
The CDC report highlighted consumption of ultra-processed food was notably higher among youth (aged 1—18), who received nearly 62 percent of their daily calories from such foods, compared to 53 percent for adults.
Among youth, the top sources of calories from ultra-processed foods were:
Sandwiches (including burgers)—7.6 percent of total calories
Sweet bakery products—6.3 percent
Savory snacks—4.9 percent
Pizza—4.7 percent
Sweetened beverages—3.9 percent
For adults, the leading contributors were:
Sandwiches (including burgers)—8.6 percent of total calories
Sweet bakery products—5.2 percent
Sweetened beverages—4.4 percent
Savory snacks—3.4 percent
Breads, rolls, and tortillas—3.1 percent
Analysis also showed consumption of ultra-processed foods was higher among lower income adults and among younger people, with adults 60 and older and young children consuming fewer calories from these sources.

What People Are Saying
Anne Williams, co-author of the report and CDC nutrition expert, said: "The results were not surprising," but added, "consumption of ultra-processed foods appeared to dip slightly over the past decade." Williams said she could not speculate on the reasons for the decline or whether consumption of less processed foods had increased.
Andrea Deierlein, a nutrition expert at New York University who was not involved in the research, stated: "People are trying, at least in some populations, to decrease their intakes of these foods," highlighting possible growing awareness among Americans about the potential harms of ultra-processed food.
What Happens Next
U.S. health officials recently said there are concerns over whether current definitions of ultra-processed foods "accurately capture" the range of foods that may affect health.
The U.S. Food and Drug Administration and the Agriculture Department recently issued a request for information to develop a new, uniform definition of ultra-processed foods for products in the U.S. food supply.

Cake Recall Update as FDA Sets Highest Concern Level for Multiple Products
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A recall of numerous cake products due to potential salmonella contamination has been issued the highest risk warning by the U.S. Food and Drug Administration (FDA). King Cheesecake Company, Inc., based in Texas, issued a voluntary recall for six products on July 18 as pecans contained with the cakes may have been contaminated. The FDA later issued a Class I risk classification for the recall on August 7. Newsweek contacted King Cheesecake Company, Inc. for comment by email outside of regular working hours. Stock image.

King Cheesecake Company, Inc. issued a voluntary recall for six products on July 18 due to potential salmonella contamination. Silas Stein/picture-alliance/dpa/AP Why It Matters A Class I risk classification represents "a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death," according to the FDA. Salmonella bacteria can cause gastrointestinal illness and fever called salmonellosis. Symptoms typically develop 12 to 72 hours after infection, and usually last between four and seven days. Typical symptoms include diarrhea, fever and abdominal cramps. People experiencing more severe infections may also suffer high fever, aches, headaches, lethargy, rashes and blood in their urine. Infections can become fatal on rare occasions, with about 450 people dying each year from salmonellosis, according to the FDA. The infection is particularly dangerous for young children, frail or elderly people, and those with weakened immune systems. What To Know The products affected by the recall include the following: Assorted Layer Cake Italian Layer Cake Carrot Layer Cake Tres Leches Cheesecake Hummingbird Layer Cake Chocolate Tres Leches Cheesecake The products were manufactured between June 20 and July 14. They were distributed to Alabama, Texas, Florida, Louisiana, Oklahoma and Illinois. What People Are Saying The Centers for Disease Control and Prevention's guidance on salmonella: "In some people, the illness may be so severe that the patient is hospitalized. Salmonella infection may spread from the intestines to the bloodstream and then to other parts of the body." The FDA, on its website: "Children younger than five, the elderly, and people with weakened immune systems are more likely to have severe salmonellosis infections. "Wash the inside walls and shelves of the refrigerator, cutting boards and countertops, and utensils that may have contacted contaminated foods; then sanitize them with a solution of one tablespoon of chlorine bleach to one gallon of hot water; dry with a clean cloth or paper towel that has not been previously used. "People with pets should take special care to avoid cross-contamination when preparing their pet's food. Be sure to pick up and thoroughly wash food dishes as soon as pets are done eating, and prevent children, the elderly, and any other people with weak immune systems from handling or being exposed to the food or pets that have eaten potentially contaminated food." What Happens Next The recall is listed as ongoing, according to the FDA. Consumers who purchased the affected products should not consume them.

How cutting out certain foods can trigger new allergies
Bagels, which often include gluten, are one of many foods often excluded in elimination diets. But for allergy-prone individuals, cutting out foods for too long may disrupt immune tolerance and trigger dangerous reactions. Photograph by Rebecca Hale, National Geographic Elimination diets are everywhere—from parents managing eczema to influencers cutting out gluten and dairy in pursuit of 'clean eating.' But research shows that removing foods from your diet can subtly change how your immune system reacts when you eat them again. In some people, especially those with conditions like eczema or past food allergies, that loss of tolerance can spark dangerous reactions—even life-threatening anaphylaxis—when the food returns. This risk is often overlooked in the growing popularity of elimination diets. According to the CDC's National Center for Health Statistics, Americans are cutting more from their plates than ever. Some do it to manage celiac disease or irritable bowel syndrome, others to reduce bloating, fatigue, or joint pain. Social media trends like #cleaneating have only amplified the appeal. By 2024, more than half of Americans reported following a specific diet or eating pattern, compared to just 38 percent in 2019. Yet for the immune system, regular exposure to food proteins helps maintain a state of tolerance—one that can be disrupted when those foods disappear from the menu for too long. Understanding how and why that shift happens is key to knowing when elimination diets help, and when they might put you at risk. The science of oral tolerance and food allergies 'The intestine has an unenviable task,' says Brian Vickery, chief of allergy and immunology and director of the food allergy program at Emory's Children's Healthcare of Atlanta. 'It has to identify and respond to a constant barrage of environmental stimuli that can be both dangerous and beneficial.' (Is gluten really that bad for you? Here's what happens when you stop eating it.) The gastrointestinal tract, which has more immune lymphocytes than any other body part, encounters trillions of microbes and more than 30 kilograms of food proteins each year. Yet, it manages to defend against harmful invaders while ignoring harmless foods and friendly bacteria. This balancing act relies on oral tolerance, a process in which immune responses to ingested food proteins are actively suppressed, which in turn prevents harmful reactions like food allergies. While the underlying immune mechanisms are not entirely understood, the latest studies indicate it begins with specialized antigen-presenting cells that capture food antigens in the gut and instruct nearby T cells to stand down. This signal gives rise to antigen-specific regulatory T cells, which calm the immune response to food proteins. (As food allergies rise, new treatments are on the horizon.) 'The gut is important in the initial establishment of tolerance,' says Michael Pistiner, director of Food Allergy Advocacy, Education and Prevention, Food Allergy Center at the MassGeneral Hospital for Children. 'If you're not already allergic, early introduction to foods can help promote tolerance and protect infants from developing a food allergy.' That protection doesn't end in childhood. Regular, ongoing exposure to foods helps maintain oral tolerance throughout life. Recent research in food allergy patients treated with oral immunotherapy, where gradually increasing doses of the culprit food are given orally, highlights how continued ingestion is often needed to maintain a desensitized state. Conversely, there's evidence that elimination diets for some can disrupt oral tolerance and encourage the immune system to develop allergies. When elimination diets increase allergy risk For parents of children with eczema, it's common to suspect certain foods are worsening flare-ups. Many turn to elimination diets in hopes of finding the culprit. But research has uncovered a hidden risk. Anne Marie Singh, professor and chief of Division of Allergy, Immunology, and Rheumatology at the University of Wisconsin-Madison, and her colleagues evaluated almost 300 children with eczema on elimination diets. (How a tick bite can cause food allergies in humans.) 'We found that if you removed the food from their diet, upon reintroduction there was a significant increase in the risk of allergic reactions, including potentially severe immediate allergic reactions,' says Singh. The results were striking: almost one in five children (19 percent) developed new immediate allergic reactions when the eliminated foods were reintroduced, even though they had no previous history of such responses. Most were mild, but alarmingly, 30 percent of reactions were severe, classified as anaphylaxis. The danger isn't limited to children. In a separate study of 30 adults who developed allergies to foods they had previously tolerated, 70 percent had been on elimination diets beforehand. Half experienced anaphylaxis, and the vast majority (80 percent) had pre-existing allergic conditions such as environmental allergies, asthma, or eczema. For people without a history of allergies, the risk appears much lower. If you're thinking about trying an elimination diet, experts say the safest approach depends on your risk level. If you're at higher risk (children or anyone with pre-existing allergy conditions), consult with a healthcare professional before starting an elimination diet. 'The more allergic you are, an elimination diet could potentially be a problem,' says Singh. Pistiner adds that 'in infants with eczema, elimination diets can be detrimental, especially at this very important time of early introduction.' Experts also recommend that children following elimination diets have close medical supervision to ensure nutritional adequacy and healthy growth. (What scientists are learning about how to prevent allergies in kids.) Duration matters, too. A shorter elimination phase gives less time for oral tolerance to break down. Singh notes that 'two to four weeks of elimination should be enough time to know if it makes a difference and also short enough to not risk an allergic reaction when you try it again.' In some cases, completely cutting out a food isn't necessary. If symptoms are mild, keeping small, tolerable amounts in the diet may help maintain oral tolerance while still easing discomfort, adds Singh.

Arbitration agreements shield assisted living homes from accountability, some experts say
Advertisement E.J. Lococo, a retired federal agent, said he thought it meant arbitration would apply if 'someone stole my mother's Depends or CD player. . . . I didn't know [that] if you were going to kill my mother, we were going to go to arbitration.' Yet, Lococo alleges, that is exactly what happened. His mother, 80, died in August 2021 from pressure ulcers that her family alleges went untreated for months while she was at the Atrium. Her son filed a wrongful death suit against Benchmark Senior Living LLC, which operates Atrium, on behalf of her estate last year. But in March, a judge granted the facility's motion to dismiss all claims against it, ruling the estate was legally required to resolve them through binding arbitration. Advertisement Facing steep filing fees and the costs of paying an arbitrator, Lococo's lawyer, Michael Grace, said he decided not to pursue arbitration against Benchmark. He is, however, going forward with claims against two outside companies that provided medical care to Judith Lococo while she lived at the Atrium, and were not included in the arbitration agreement. The case underscores the impact of arbitration agreements, which are legal and common in the assisted living industry, but severely restrict residents from holding facilities accountable when something goes wrong, according to elder care lawyers and advocates. 'Americans are more likely to be struck by lightning than win in forced arbitration,' according to a 2019 report by the American Association for Justice, a Washington, D.C.-based nonprofit organization for trial lawyers. Moreover, critics say, residents of assisted living facilities and their family members don't realize the implications of what they're signing. They also don't have to put themselves in that situation: they are not required to sign arbitration agreements as a condition of admission, these critics said, and should not do so. Unlike court proceedings, an arbitrator is privately paid, usually with both sides sharing the expense, which can cost plaintiffs thousands of dollars. Court rules don't apply, meaning plaintiffs may not call as many witnesses or obtain as much evidence as they believe they need to support their case. The arbitrator, usually just one person, is supposed to be neutral. But critics say the facilities too often have a preexisting relationship with an arbitrator who is likely to favor their side. And when arbitrators do rule in favor of plaintiffs, judgments tend to be much lower than those awarded by juries. Advertisement In Lococo's case, the arbitration agreement even included a clause that would require the family to pay Benchmark's legal fees if it filed a lawsuit. Benchmark declined to comment on Lococo's allegations, but said in a statement released by its lawyer that it 'places its highest priority on the care, safety and well-being of our residents.' The lawyer, Joseph M. Desmond, said in an email, 'We stand firmly behind the quality of care we provide and our attentive staff, whose skills consistently receive high marks for resident satisfaction.' He added that Benchmark's policy is 'to offer a voluntary arbitration agreement to individuals moving into our communities' and that arbitration 'is entirely optional and not a requirement for residency.' The Massachusetts Assisted Living Association, which advocates for the assisted living industry in the state, said arbitration has the advantage of resolving disputes more quickly and at a lower cost than through litigation. Arbitration agreements can be negotiated and amended before a resident moves into a home, a spokesperson said. 'Residents and families sometimes select an option for arbitration when they move in so that if they have concerns they can resolve them in a way that is both timely and less costly than litigation,' said Brian Doherty, the group's president. The devastating blaze that killed 10 residents of an assisted living facility in Fall River in July drew attention to the lack of transparency in the industry, which in Massachusetts is more loosely regulated than nursing homes. And, critics say, arbitration agreements contribute to that lack of transparency because the proceedings are not public and settlements are confidential. Those conditions can obscure from public view problems and dysfunction at a facility, details that would come to light in court proceedings. Advertisement Arbitration agreements, so far, at least, appear not to be a factor in the Fall River case. 'It has not come up in our case at this point,' said Robin Gouveia, who filed the first lawsuit on behalf of a Gabriel House resident. Arbitration agreements also include a clause requiring that residents agree not to sue the home or seek other court remedies. 'There's a constitutional right to have a jury and an arbitration clause takes it away with the swipe of a pen,' said David J. Hoey, an attorney who has represented families alleging abuse and neglect at nursing homes and assisted living centers for more than 30 years. 'I've arbitrated enough cases to know that they're unfair to the injured party.' In 2019, he filed a wrongful death suit on behalf of the estate of a client who was allegedly shoved to the ground by another resident at an assisted living home in Danvers, broke his hip, and later died of complications from the injury. A judge dismissed the suit against the operators, citing an arbitration agreement. The arbitrator ruled in favor of Hoey's client. But he said the judgment of $360,000, was much less than Hoey believed a jury would have awarded. The state attorney general's office is drafting new consumer protections for the assisted living industry, but a spokesperson would not say whether changes to arbitration clauses are under consideration. As attorney general in 2017, now-Governor Maura Healey signed on to a letter with counterparts from 16 states that criticized arbitration agreements and opposed a federal proposal to lift a ban on their use in nursing homes. Advertisement The federal government lifted its ban on arbitration clauses in nursing homes following a legal challenge. Instead, in 2019 it adopted new requirements, prohibiting nursing homes from denying admission to anyone who refused to agree to arbitration and allowing residents or their representatives 30 days to change their mind if they do sign one. Assisted living facilities, which are not regulated by the federal government, are not bound by the same arbitration requirements as nursing homes, but generally have adopted the same standards, according to Hoey. A Massachusetts commission formed this year to consider new regulations for the industry recommended a ban on them as a condition of admission in a draft proposal. Other states differ on how they regulate such clauses. Hoey said the agreements aren't foolproof and can be challenged in court on various grounds, including if they were signed by a person who didn't have legal authority to represent a resident or was under duress. Lococo's son said he tapped into his retirement savings to pay for his mother's care, including more than $13,000 a month to the Atrium at Cardinal Drive. Several months after she moved, COVID-19 swept the country, and the facility was placed in lockdown. Lococo said there were staffing shortages and he feared his mother wasn't getting the care they were paying for, which included assistance with bathing, toiletry, and medical treatment. She fell several times in late 2020, and developed bed sores, according to the lawsuit. Advertisement But, Lococo said, nobody at the facility ever told him his mother had developed a pressure ulcer around May 2021 that had allegedly gone untreated. He said he learned of it when the family moved her to another facility three months later and a nurse sent him graphic photos of her wound, showing exposed bone. 'I was enraged,' Lococo said. His mother died days later. 'These places that call themselves assisted living fly under the radar. . . How is this not regulated?' Lococo's attorney, Michael Grace, said family members generally don't think about something bad happening to their relatives after spending so much time and emotional energy finding an assisted living home for them. They waive their right to sue, he said, because they're thinking 'it looks like a good place and nothing is going to go wrong.' Shelley Murphy can be reached at
