In 57 healthy-weight adults, nutritionally matched ultraprocessed food meals produce greater insulinaemic and energetic responses and lower peak carbohydrate oxidation than non-UPF meals.
- Why it matters: UPF intake is linked to higher disease burden, but it is unclear how processing changes post-ingestive metabolism and brain responses beyond calories and macronutrients.
- What they did: In a randomized crossover design, participants consumed nutritionally matched UPF or non-UPF meals; researchers measured post-meal insulin/energy and carbohydrate oxidation, alongside brain activity during food cues.
- The result: Differences in peak carbohydrate oxidation track with striatal activation to food cues, and valuation-related brain correlations are positive for non-UPF but negative for UPF in visual cortex and striatum.
