Most diet programs focus on weight loss or meeting nutritional guidelines, but they often overlook the impact of ultra-processed foods (UPFs). Despite being linked to serious health risks, UPFs remain a major part of modern diets. A new study from Drexel University set out to change that by testing an intervention aimed at reducing UPF consumption—and the results were striking.
Understanding Ultra-Processed Foods
UPFs are industrially manufactured foods that undergo extensive processing. These include packaged snacks, sugary cereals, instant noodles, and even some protein bars. They often contain additives like preservatives, artificial flavors, and emulsifiers, making them hyper-palatable and convenient but nutritionally poor.
Research has linked UPFs to obesity, diabetes, heart disease, and mental health issues. Yet, they remain widely consumed due to their accessibility, affordability, and marketing as quick and even “healthy” options.
The Drexel University Intervention
To help people reduce UPF intake, researchers developed a two-month program that combined mindfulness strategies, one-on-one meal planning, and household involvement. Financial support was also provided to participants, helping them afford healthier food choices.
The study involved 14 adults who were overweight or obese and consumed at least two UPF items daily. On average, participants reduced their UPF intake by nearly half.
Promising Results
By the end of the study, participants saw significant improvements:
- UPF intake was cut nearly in half.
- Daily calorie consumption dropped by over 600 calories.
- Sugar intake declined by 50%.
- Saturated fat intake decreased by 37%.
- Sodium consumption fell by 28%.
- Participants lost an average of 7.7 pounds.
Interestingly, fruit and vegetable intake did not increase significantly, suggesting that future interventions may need to emphasize the importance of whole, nutrient-dense foods.
Psychological Benefits
Beyond physical improvements, participants reported feeling better mentally and emotionally. Many noticed enhanced mood, more energy, and a greater sense of control over their eating habits. Because UPFs can trigger addiction-like behaviors, cutting back may help regulate emotions and improve mental clarity.
Next Steps
“The findings suggest that people can reduce their UPF intake if given the right tools and support,” said lead researcher Dr. Charlotte Hagerman.
The research team plans to expand the study to a larger population, exploring which strategies work best across different demographics. The long-term goal is to shape policies that promote healthier eating habits and make whole foods more accessible.
The Bigger Picture
This study underscores the need for public awareness and policy changes to reduce UPF consumption. Since UPFs dominate the food supply, solutions must address both education and affordability. Community-based programs, financial incentives, and better food labeling could all play a role in shifting dietary habits.
As research continues, findings like these could influence the way we approach nutrition and public health, ultimately leading to healthier communities.
