Tree nuts stabilize blood sugar

Eating tree nuts appears to help lower and stabilize blood sugar levels in people with type 2 diabetes, say researchers.

Their meta-analysis of evidence from 12 clinical trials involving 450 participants shows eating about two servings a day improves HbA1c and fasting glucose test results.

The best results were seen when tree nuts replaced refined carbohydrates rather than saturated fats, says Canadian researcher Dr John Sievenpiper of St Michael's Hospital.
