For years, health experts have warned that ultra-processed foods are quietly driving America’s exploding rates of obesity, diabetes, heart disease, and metabolic dysfunction. But one major problem kept slowing meaningful action: nobody could even fully agree on what “ultra-processed food” actually meant.
Now, a major new report released by Healthy Eating Research may have changed that.
The report, assembled by a panel of nutrition scientists, food policy attorneys, and public health experts over nearly a year of meetings and analysis, offers perhaps the clearest and most politically actionable framework yet for identifying ultra-processed foods — and for regulating them.
And the scope of the issue is staggering.
According to the research cited in the report, more than half of all calories consumed by American adults now come from ultra-processed foods. For children, the percentage is even higher. One recent study examining baby and toddler foods sold in major grocery chains found that roughly 71 percent qualified as ultra-processed.
That matters because these products increasingly dominate the modern American diet.
Ultra-processed foods are not simply ordinary processed foods like canned vegetables, frozen fruit, or fermented products humans have safely consumed for generations. Instead, they occupy the far end of the industrial food spectrum — products heavily manufactured from extracted ingredients, additives, artificial flavorings, stabilizers, emulsifiers, colorings, and chemically engineered compounds rarely found in any home kitchen.
The list includes many of the most common items filling grocery aisles today: flavored chips, sugary cereals, packaged breads, processed meats, frozen dinners, candy, sweetened beverages, flavored yogurts, chicken nuggets, and countless snack foods engineered for maximum shelf life and maximum consumption.
The report’s authors argue that focusing narrowly on calories, fat, or sugar content misses the larger issue entirely.
Research increasingly suggests the industrial processing itself may independently harm human health.
Studies cited in the report found that people eating diets high in ultra-processed foods face elevated risks of obesity, type 2 diabetes, cardiovascular disease, depression, anxiety, and even early death — even after controlling for standard nutritional measurements. In controlled trials, participants consuming ultra-processed meals consistently ate more calories and reported feeling less full than participants eating minimally processed foods with nearly identical nutrient profiles.
Scientists believe several factors may be driving the effect.
Ultra-processed foods are often engineered to digest rapidly, triggering sharp blood sugar spikes and disrupting satiety signals. Some additives and artificial sweeteners may alter gut bacteria and increase inflammation. Packaging materials themselves may expose consumers to chemical contaminants. And perhaps most concerning, researchers increasingly suspect certain ultra-processed foods may trigger addictive-like responses in the brain similar to those seen with nicotine or other addictive substances.
Foods combining refined carbohydrates and fats appear especially capable of driving compulsive overeating and cravings.
The political momentum surrounding the issue has accelerated rapidly.
Researchers found that while only eight state or federal proposals targeting ultra-processed foods emerged between 2021 and 2024, another 32 proposals appeared during just the first half of 2025 alone. The FDA, USDA, and Department of Health and Human Services are now all reportedly working toward developing an official federal definition.
That is where this new report becomes especially significant.
The expert panel ultimately recommended defining ultra-processed foods primarily through ingredient analysis. Under their proposed framework, foods containing specific industrial additives or marker ingredients not commonly used in home cooking would qualify as ultra-processed.
The report also outlines concrete policy recommendations lawmakers could implement immediately.
Top-tier proposals include targeted taxes on selected ultra-processed products, warning labels on packaging, restrictions on school and childcare procurement, and public awareness campaigns similar to anti-smoking efforts.
Notably, the panel repeatedly emphasized concerns about economic fairness. Lower-income Americans currently consume disproportionately high amounts of ultra-processed foods, largely because these products are cheap, heavily marketed, widely available, and often more convenient than healthier alternatives. Researchers stressed that any future regulations must avoid further burdening working families already struggling with food costs.
Still, the broader message of the report is unmistakable.
America’s modern food environment did not emerge accidentally. Many of the most common products lining supermarket shelves were specifically engineered over decades to maximize convenience, profitability, shelf stability, and repeat consumption. The result is a food system increasingly dominated by products that researchers now believe may be fundamentally damaging public health on a massive scale.
This new report gives policymakers something they have lacked for years: a workable definition and a roadmap for action.
Whether Washington actually acts on it is another question entirely.
