Government funding for ultra-processed food research nearly quadrupled between 2016 and 2025, growing from $3.3 million to $12 million annually, according to Gram Research analysis of 81 NIH-supported projects. This surge reflects growing scientific consensus that ultra-processed foods contribute to obesity, heart disease, diabetes, and cancer—conditions costing America over $1.1 trillion yearly. However, researchers identified critical gaps: most studies focus on obesity rather than food access, and we still lack complete understanding of how these foods damage our bodies at a biological level.
According to Gram Research analysis, the U.S. government is investing significantly more money into understanding how ultra-processed foods affect our health. Researchers found that funding for this type of research nearly quadrupled between 2016 and 2025, growing from $3.3 million to $12 million per year. Scientists are studying how these foods might contribute to serious health problems like heart disease, obesity, and diabetes—conditions that cost America over $1.1 trillion annually. While most studies focus on obesity, researchers say there’s a big gap in understanding how food environments and food access affect people’s health, and how exactly these processed foods damage our bodies at a biological level.
Key Statistics
A 2025 NIH analysis of 81 government-funded research projects found that funding for ultra-processed food research increased from $3.3 million in 2016 to $12 million in 2025, with active projects growing from 8 to 22.
According to research reviewed by Gram, diet-related chronic diseases linked to ultra-processed foods account for over 1 million deaths annually in the U.S. and cost the economy more than $1.1 trillion in healthcare and lost productivity.
A 2025 NIH portfolio review found that 58 of 81 ultra-processed food research projects studied health conditions, while only 29 were intervention studies testing whether changing food access or policies improved outcomes.
The 2025 NIH analysis identified that 49 of 81 ultra-processed food projects were basic research examining biological mechanisms, with 32 specifically studying how human bodies respond to ultra-processed food exposure.

The Research Details
Researchers at the National Institutes of Health reviewed all government-funded research projects focused on ultra-processed foods from 2016 to 2025. They started with 520 projects and carefully examined each one to identify which ones specifically studied ultra-processed foods. They found 81 projects that met their criteria and organized them by type: some studied how these foods affect health conditions, some tested interventions like policy changes or lifestyle programs, and others examined the biological mechanisms—basically how these foods damage our bodies at the cellular level.
The team categorized the research into different types: 58 projects studied health conditions related to ultra-processed food consumption, 29 were intervention studies testing whether changing food access or policies improved health, and 49 were basic research projects examining how these foods affect human biology. They tracked funding amounts and the number of active projects year by year to show how government investment has grown.
This type of review is important because it shows us what scientists actually know about ultra-processed foods and what major gaps remain. By mapping out all the government-funded research, we can see which health problems have been studied thoroughly and which ones need more attention. This helps guide future research priorities and tells us which health claims about ultra-processed foods have solid scientific backing.
This is a comprehensive review of government-funded research, which means it captures legitimate, peer-reviewed studies. The data comes from official NIH records, making it reliable. However, this review doesn’t evaluate the quality of individual studies—it just counts and categorizes them. The findings show trends in research investment rather than proving anything about ultra-processed foods themselves.
What the Results Show
Government funding for ultra-processed food research has grown dramatically. In 2016, only 8 projects received funding totaling $3.3 million. By 2025, that number jumped to 22 active projects with $12 million in funding—nearly a fourfold increase in money and nearly triple the number of projects. This shows that the U.S. government is taking ultra-processed foods seriously as a public health issue.
Most of the research (58 out of 81 projects) focused on how ultra-processed foods relate to specific health conditions, with obesity being the most studied. About 29 projects were intervention studies—meaning researchers actually tested whether changing people’s food access, food environment, or lifestyle improved their health. The remaining projects were basic research examining how ultra-processed foods affect our bodies at a biological level, including studies on human mechanisms and some that combined human and animal research.
The research portfolio shows that scientists are approaching this problem from multiple angles. Some are studying what happens when people eat these foods, others are testing whether policy changes help, and still others are trying to understand the biological pathways that connect ultra-processed foods to disease.
The review identified important research gaps. While obesity received substantial attention, fewer studies examined food access and food insecurity—meaning we don’t fully understand how poverty and limited food choices drive ultra-processed food consumption. Additionally, researchers noted a critical gap in mechanistic research: we still don’t have clear answers about exactly how ultra-processed foods cause disease at the biological level, and we lack validated biomarkers (biological markers) that could help identify when someone’s health is being damaged by these foods.
This review shows that ultra-processed food research is becoming a priority. The increase from $3.3 million to $12 million in funding reflects growing recognition that these foods are linked to major health problems. Previous research has suggested connections between ultra-processed foods and heart disease, diabetes, and cancer, but this review shows that scientists are now getting more resources to understand these connections deeply and test solutions.
This review only counts and categorizes research projects—it doesn’t evaluate whether individual studies are well-designed or whether their findings are reliable. The review focuses on government-funded research, so it misses studies funded by universities, private companies, or other sources. Additionally, the review was completed in December 2025, so very recent research might not be included. The review also doesn’t tell us what these studies actually found about ultra-processed foods, only what types of research are being done.
The Bottom Line
The research suggests that reducing ultra-processed food consumption is important for health (moderate to strong evidence based on growing research investment). However, the research gaps mean we don’t yet have complete answers about exactly which ultra-processed foods are most harmful or the best ways to change eating habits. Focus on eating more whole foods and fewer packaged, processed items, but expect more specific guidance as research continues.
Everyone should care about this research, especially people with obesity, heart disease, diabetes, or cancer risk. People living in areas with limited access to fresh food should particularly pay attention, as this is an identified research gap. Policymakers and food companies should also follow this research to understand how to improve food environments.
Changes in eating habits typically show health benefits within weeks to months for some markers (like blood sugar), but major health improvements like weight loss or disease prevention may take months to years. As research continues through 2025 and beyond, we should expect clearer guidance on which specific foods to avoid and which interventions work best.
