Meta-analysis reveals high ultra-processed food intake reduces overall dietary quality in nationally representative populations, indicating a primary driver of nutrient deficiencies.

Key Points

To quantify the relationship between the consumption of ultra-processed foods categorized by the NOVA classification system and the overall dietary and nutrient profile across nationally representative populations.
Conducted a systematic search of electronic databases for nationally representative surveys published prior to July 2021 reporting nutrient intake by NOVA food categories.
Modeled associations between ultra-processed food consumption and dietary nutrient variables using ordinary least squares linear regression on aggregated survey data.
Ultra-processed foods contributed up to 80% of total caloric intake in the US and Canada, led by confectionery and sugar-sweetened beverages.
An inverse linear relationship was identified between consumption of ultra-processed foods and intake of minimally processed foods.
Elevated intake of ultra-processed foods correlated with increases in free sugars, total fats, and saturated fats, alongside concurrent decreases in dietary fiber, protein, potassium, zinc, magnesium, and vitamins A, C, D, E, B12, and niacin.
