More than half of the calories Americans consume come from ultra-processed foods, according to a new federal report. These foods, often loaded with sugar, salt, and unhealthy fats, are convenient and appealing but raise serious concerns about long-term health.CDC Confirms Long-Suspected TrendsWhile nutrition experts have long suspected that ultra-processed foods dominate the American diet, this is the first time the U.S. Centers for Disease Control and Prevention (CDC) has confirmed it using recent nationwide data. The analysis covers dietary patterns from August 2021 to August 2023.The findings come amid increasing concern from public health officials. U.S. Health Secretary Robert F. Kennedy Jr. has pointed to ultra-processed foods as a major driver of chronic illness in the country. In a recent interview, he said, “We are poisoning ourselves and it's coming principally from these ultra-processed foods.”Who Is Eating What?The report shows that Americans aged 1 and older got 55 percent of their daily calories from ultra-processed foods. For children and teenagers, that figure jumps to nearly 62%. Adults consumed a slightly lower share at around 53%.Some of the most common sources include sweet baked goods, burgers and sandwiches, savory snacks, pizza, and sugary drinks. The data also revealed differences across age and income groups. Young children consumed fewer ultra-processed calories than older children, and adults aged 60 and older ate less of them than younger adults. People with lower incomes were more likely to consume ultra-processed foods compared to those with higher incomes.A Small but Notable ShiftAnne Williams, a CDC nutrition researcher and one of the report’s authors, noted that although the overall numbers are high, there has been a slight dip in consumption over the past decade. Among adults, intake dropped from 56 percent in 2013-2014, and among kids, it declined from nearly 66 percent in 2017-2018.The reason for the decline is unclear. Williams said the report does not explain whether people are choosing less-processed alternatives. However, Andrea Deierlein, a nutrition expert at New York University, suggested the drop could reflect growing awareness of the risks tied to ultra-processed foods, as reported by the Associated Press (AP).“People are trying, at least in some populations, to decrease their intakes of these foods,” Deierlein said.Why It MattersResearch has repeatedly linked ultra-processed foods to obesity, diabetes, and heart disease. However, establishing a direct cause-and-effect relationship has proven challenging. Still, a number of studies show that people tend to eat more calories and gain weight when consuming ultra-processed foods compared to minimally processed ones, even when the nutritional content appears similar.A recent study published in Nature supported this pattern. Participants who followed a minimally processed diet lost twice as much weight as those eating ultra-processed meals, including seemingly healthy options like protein bars and ready-to-heat frozen dishes.What Counts as Ultra-Processed?Defining what qualifies as ultra-processed can be tricky. The CDC used the Nova classification system, which sorts foods based on the degree of processing. Ultra-processed items are often energy-dense, low in fiber, and high in additives like sweeteners, salt, and unhealthy fats.The FDA and U.S. Department of Agriculture are now working on a clearer definition for regulatory use, having recently requested public input on the matter.What Can Consumers Do?Until clearer guidelines are in place, experts like Deierlein recommend reducing ultra-processed food intake. That could mean choosing plain oats over flavored instant versions or reading ingredient lists to spot added sugars, sodium, and preservatives.“I do think there are less-processed options available for many foods,” she said.
