What Are Ultra-Processed Foods (UPF)?
UPF contribute approximately 67% of total energy intake for U.S. youth aged 2 to 19 and about 57% for adults in the U.S.¹⁻³
Ultra-processed foods are linked to weight gain and chronic diseases such as obesity, type 2 diabetes, depression, cancer, and cognitive decline.
UPF are industrial formulations that contain ingredients (i.e.,high-fructose corn syrup, modified starches) and/or additives (i.e., flavors, colors, artificial sweeteners) not commonly found in your kitchen. For a more detailed description, see Nova Group 4 below.

Why We Must Decrease Ultra-Processed Foods
The American Medical Association published a viewpoint, April 1, 2025 titled: The 2025-2030 Dietary Guidelines—Time for Real Progress by Dariush Mozaffarian, MD, Dr.PH.
“If we were a hale and hearty populace, enjoying and thriving on the fruits of the earth, it would be reasonable to wait for more research. But when 3 of 4 adults have overweight or obesity, 1 of 2 adults and 1 of 4 teenagers have diabetes or prediabetes, and only 7% of adults are metabolically healthy, we face a national nutrition crisis requiring urgent action. Diet-related diseases further drive enormous burdens of health care spending, lost productivity, military unpreparedness, reduced economic competitiveness, and health disparities—with the latter well highlighted in the DGAC report.
Based on the current evidence and high levels of consumption, it is time to recommend that people in the US eat fewer UPFs”
The Nova classification system helps identify Ultra-processed foods.
It is widely used by researchers as a standardized framework to ensure consistency in studying and understanding the impact of ultra-processed food consumption.
It categorizes foods based on the extent and degree to which they have been industrially processed.
UPF research is evolving, and new food substances deemed edible are entering the market, expanding Nova Group 4 foods.
The Non-UPF program defines UPF as Nova Group 4 foods. Therefore, any food that falls into Nova groups 1 through 3 is considered a non-ultra-processed food.
