Introduction to Ultraprocessed Foods<\/h1>\n

The Trump administration\u2019s quest to \u201cMake America Healthy Again\u201d has put ultraprocessed foods in the spotlight. Robert F. Kennedy Jr., the nation\u2019s new health secretary, has cited \u201chighly chemically processed foods\u201d as a chief culprit behind an epidemic of chronic disease in the U.S., including ailments such as obesity, diabetes, and autoimmune disorders. Such foods are \u201cpoisoning\u201d people, particularly children, Kennedy said during Senate confirmation hearings. He has vowed to work to remove such foods from federal programs such as the Supplemental Nutrition Assistance Program, or SNAP.<\/p>\n

What are Ultraprocessed Foods?<\/h2>\n

Most foods are processed, whether it\u2019s by freezing, grinding, fermentation, pasteurization, or other means. In 2009, Brazilian epidemiologist Carlos Monteiro and colleagues first proposed a system that classifies foods according to the amount of processing they undergo, not by nutrient content. At the top of the four-tier scale are foods created through industrial processes and with ingredients such as additives, colors, and preservatives that you couldn\u2019t duplicate in a home kitchen, said Kevin Hall, a researcher who focuses on metabolism and diet at the National Institutes of Health.<\/p>\n

Classification of Ultraprocessed Foods<\/h3>\n

These foods are often made to be both cheap and irresistibly delicious, said Dr. Neena Prasad, director of the Bloomberg Philanthropies\u2019 Food Policy Program. \u201cThey have just the right combination of sugar, salt, and fat and you just can\u2019t stop eating them,\u201d Prasad said. However, the level of processing alone doesn\u2019t determine whether a food is unhealthy or not, Hall noted. Whole-grain bread, yogurt, tofu, and infant formula are all highly processed, for instance, but they\u2019re also nutritious.<\/p>\n

Are Ultraprocessed Foods Harmful?<\/h2>\n

Many studies suggest that diets high in such foods are linked to negative health outcomes. But these kinds of studies can\u2019t say whether the foods themselves are the cause of the negative effects \u2014 or whether there\u2019s something else about the people who eat these foods that might be responsible. Ultraprocessed foods, as a group, tend to have higher amounts of sodium, saturated fat, and sugar, and tend to be lower in fiber and protein. It\u2019s not clear whether it\u2019s just these nutrients that are driving the effects.<\/p>\n

Research on Ultraprocessed Foods<\/h3>\n

Hall and his colleagues were the first to conduct a small but influential experiment that directly compared the results of eating similar diets made of ultraprocessed versus unprocessed foods. Published in 2019, the research included 20 adults who went to live at an NIH center for a month. They received diets of ultraprocessed and unprocessed foods matched for calories, sugar, fat, fiber, and macronutrients for two weeks each and were told to eat as much as they liked. When participants ate the diet of ultraprocessed foods, they consumed about 500 calories per day more than when they ate unprocessed foods, researchers found \u2014 and they gained an average of about 2 pounds (1 kilogram) during the study period. When they ate only unprocessed foods for the same amount of time, they lost about 2 pounds (1 kilogram).<\/p>\n

Should Ultraprocessed Foods be Regulated?<\/h2>\n

Some advocates, like Prasad, argue that the large body of research linking ultraprocessed foods to poor health should be more than enough to spur government and industry to change policies. She calls for actions such as increased taxes on sugary drinks, stricter sodium restrictions for manufacturers, and cracking down on marketing of such foods to children. \u201cDo we want to risk our kids getting sicker while we wait for this perfect evidence to emerge?\u201d Prasad said.<\/p>\n

Regulation and Policy<\/h3>\n

Last year, former FDA Commissioner Robert Califf broached the subject, telling a conference of food policy experts that ultraprocessed foods are \u201cone of the most complex things I\u2019ve ever dealt with.\u201d But, he concluded, \u201cWe\u2019ve got to have the scientific basis and then we\u2019ve got to follow through.\u201d<\/p>\n

How Should Consumers Manage Ultraprocessed Foods at Home?<\/h2>\n

In countries like the U.S., it\u2019s hard to avoid highly processed foods \u2014 and it\u2019s not clear which ones should be targeted, said Aviva Musicus, science director for the Center for Science in the Public Interest, which advocates for food policies. \u201cThe range of ultraprocessed foods is just so wide,\u201d she said. Instead, it\u2019s better to be mindful of the ingredients in foods. Check the labels and make choices that align with the current dietary guidelines, she suggested.<\/p>\n

Consumer Advice<\/h3>\n

\u201cWe have really good evidence that added sugar is not great for us. We have evidence that high-sodium foods are not great for us,\u201d she said. \u201cWe have great evidence that fruits and vegetables which are minimally processed are really good for us.\u201d It\u2019s essential not to vilify certain foods, she added. Many consumers don\u2019t have the time or money to cook most meals from scratch. \u201cFoods should be joyous and delicious and shouldn\u2019t involve moral judgment,\u201d Musicus said.<\/p>\n

Conclusion<\/h2>\n

Ultraprocessed foods make up a significant portion of the U.S. diet, and their impact on health is a topic of ongoing debate. While some research suggests a link between these foods and negative health outcomes, more definitive studies are needed to fully understand their effects. Consumers can take steps to manage their intake of ultraprocessed foods by being mindful of ingredients and choosing whole, minimally processed foods whenever possible.<\/p>\n
