SOURCE-LINKED STUDY SUMMARY
Corn protein alone, or in blends, stimulates muscle protein synthesis comparable to milk protein, with or without resistance exercise, in older adults.
Abstract summarizedQuality not appraised
- What was studied
- A randomized acute-feeding trial compared corn, pea/corn and milk proteins for muscle protein synthesis.
- Who / model studied
- 48 healthy older adults, average age 68; equal numbers of men and women.
- Studied dose & schedule
- One oral 20 g protein serving versus low-energy nonprotein placebo. Participants exercised one leg; the other provided a resting comparison.
- What the study found
- Protein-synthesis increases from baseline were 216 percent with corn, 217 percent with pea/corn, 138 percent with milk and 77 percent with placebo. Protein groups exceeded placebo; no active-protein difference was detected. Exercise further increased synthesis.
- Limitations & context
- Abstract-based assessment. These percentages measure acute synthesis, not muscle gained. Large variability and a nonsignificant comparison do not establish equivalence or corn superiority. Long-term hypertrophy, safety and exact sampling duration were not established by the accessed abstract.
