You are what you eat.
In a randomized, 2×2 crossover nutrition trial of healthy men, ultra-processed food (UPF)—even when calories were matched—worsened body composition, lipids/blood pressure, key hormones, and s***m motility trends within 3 weeks. Prevention isn’t a slogan; it’s strategy.
Five Key Takeaways (from this trial)
• Not just calories: UPF led to ~1.3–1.4 kg weight gain and ~1.0 kg fat-mass increase vs unprocessed, independent of caloric load. (Adequate & excess arms)
• Atherogenic shift: LDL:HDL ratio increased on UPF (adequate-calorie arm); diastolic BP rose on UPF (excess-calorie arm).
• Endocrine disruption signal: UPF lowered FSH (excess arm) and showed a downward testosterone trend (adequate arm), with GDF-15 decreased and leptin trending up—a hormonal milieu favoring adiposity.
• Male fertility risk markers: Total s***m motility trended down on UPF (excess arm). Concentration unchanged; directionality matters.
• Industrial exposures: UPF showed a trend to higher serum phthalate (cxMINP)—consistent with packaging/processing exposure pathways relevant to metabolism and reproduction.
