Researchers with Bichat Hospital in Paris split 18 diabetic rats into three dietary groups, monitoring their abdomens with a sponge that collected wound healing fluid. The dietary groups were:
- standard diet
- high protein
- high protein supplemented with arginine and proline
The rats that ate the high protein diet supplemented with arginine and proline healed their wounds more effectively and quickly than those that didn’t eat this diet. They showed new blood vessel growth on day five, and the macrophages revealed less cytokine stimulation and inflammation, according to Medical News Today.
