Effects of Moringa oleifera leaves on the blood glucose, blood pressure, and lipid profile of type 2 diabetic subjects: A parallel group randomized clinical trial

This Nigerian study examined whether eating fresh Moringa oleifera leaves could help people with type 2 diabetes manage their blood sugar, blood pressure, and cholesterol levels. Researchers divided 40 diabetic participants into four groups: one control group and three groups eating different amounts of fresh moringa leaves daily (20g, 40g, or 60g) for two weeks. The study found that participants eating 40g of fresh leaves daily experienced a significant drop in their systolic blood pressure, falling from 136 mmHg to 124 mmHg. However, blood sugar levels didn't show significant improvements across any of the groups during the short study period. The research is notable for using fresh leaves rather than processed extracts, which is more practical for communities where moringa trees grow naturally. While the blood pressure results are encouraging, the study's very short duration of just 14 days and small sample size of only 10 people per group limit the strength of conclusions that can be drawn.
