What specific disease state progression did purple corn extract (PCE) protect against in rat models?
Answer
Diabetic nephropathy
The primary focus of research linking purple corn to kidney health originates from controlled animal studies, specifically involving rats that were either bred or chemically induced to have diabetes. In these established models of metabolic disorder, dietary supplementation using purple corn extract (PCE) demonstrated significant protective effects. This protection was observed against both the initial development and the subsequent progression of nephropathy, which is the term used for kidney disease, especially when that disease is secondary to chronic diabetes.
