US EditionHarvard Study Finds Eating More Plants Reduces Diabetes Risk
- An American research team led by Dr. Fenglei Wang presented on June 3, 2025, that higher phytosterol intake lowers type 2 diabetes and heart disease risk in US adults.
- The researchers pooled data from three large cohort studies involving over 200,000 mostly female health professionals with up to 36 years of follow-up.
- Participants with the highest phytosterol consumption, mainly from nuts, fruits, vegetables, and whole grains, showed better insulin regulation, less inflammation, and gut microbiome differences.
- Those in the top 20% of phytosterol intake had a 9% lower heart disease risk and an 8% lower diabetes risk , with Wang stating phytosterols could be “instrumental” in risk reduction.
- The observational study supports dietary guidelines favoring plant-based foods rich in phytosterols but cannot prove causation, though biomarker and microbiome evidence strengthens the findings.
