Northeastern University researchers have developed a machine learning tool called FoodProX that predicts the level of processing in a food product. The tool uses the U.S. Department of Agriculture’s Food and Nutrient Database for Dietary Studies to score the level of processing in a respective food product. The algorithm produces an output that represents the likelihood that respective food falls into one of the four categories of the NOVA food classification system, and assigns each product a single score between zero (which signifies minimally or unprocessed food) and 100 (highly ultra-processed food). FoodProX bridges gaps in the current nutrient databases and provides a higher resolution analysis of processed foods. This development is significant for researchers examining the health impacts of processed foods.
## Key Facts:
– FoodProX is a machine learning tool that predicts the level of processing in a food product.
– The tool uses nutritional information from the U.S. Department of Agriculture’s Food and Nutrient Database.
– The AI tool confirmed that more than 73% of the U.S. food system is ultra-processed.
## Tool Architecture and Features:
FoodProX is a machine learning algorithm that accurately predicts the degree of processing for any food. The tool utilizes nutritional labeling information provided by the U.S. Department of Agriculture’s Food and Nutrient Database for Dietary Studies as inputs to score the level of processing in a given food product. FoodProX produces an output that represents the likelihood that respective food falls into one of the four categories of the NOVA food classification system. It assigns each product a single score between zero (which signifies minimally or unprocessed food) and 100 (highly ultra-processed food). FoodProX also bridges gaps in the current nutrient databases and classifies complex recipes and mixed foods and meals, allowing higher resolution analysis of processed foods.
## Findings:
Northeastern University researchers found that work in the nutrition and public health domains concerning food processing lacked a systematic way to look at a food and assess its properties, limiting research possibilities. Therefore, FoodProX helps to assess an individual’s diet quality, offering predictive power over 200+ health variables, telling us the impact of replacing processed foods with less processed alternatives of the same item, resulting in personalized dietary shifts with minimal effort. Moreover, over 73% of the U.S. food system is ultra-processed, indicating severe health implications on metabolic syndrome, diabetes, angina, elevated blood pressure, and biological age. The increased reliance of an individual’s diet on ultra-processed food reduces the bioavailability of vitamins. Finally, replacing foods with less processed alternatives can significantly reduce the health implications of ultra-processed food, suggesting that access to information on the degree of processing, currently unavailable to consumers, could improve population health.
## Conclusion:
FoodProX is a significant development for the food industry as nutrient databases currently provide limited coverage in differentiating between degrees of processing, hindering consumer choices and slowing research on the health implications of processed food. The tool was useful in bridging gaps in the nutrient databases and provided a higher resolution analysis of processed foods. It also allowed researchers to examine the health impacts of processed foods more thoroughly and accurately. Moreover, with the increased reliance of an individual’s diet on ultra-processed food correlating with severe health implications, FoodProX’s predictive power will allow for personalized dietary shifts to reduce these health implications.
