UPFs: Processing or Nutrition: The Real Health Culprit?
13 Jun
Summary
- Processing alone may not cause UPF harm, new review suggests.
- Nutritional content, not processing, likely drives UPF health risks.
- Nutritional guidelines should focus on poor nutrition, not UPF labels.
A new review published in the journal Science suggests that the adverse health effects linked to ultra-processed foods (UPFs) are likely due to their nutritional properties rather than the processing itself. Researchers examined five randomized controlled trials and found weak evidence supporting an independent, processing-specific effect of UPFs on body weight or cardiometabolic health.
This finding aligns with previous statements that observational studies on UPFs cannot definitively prove cause and effect. The review highlights that many UPFs share problematic nutritional qualities, such as being calorie-dense and rapidly consumed. Experts now recommend that nutritional guidelines should prioritize foods based on their nutritional poverty and calorie density over the broad UPF classification.
