  • In patients with diabetes with a better glycaemic control, incorporating almonds (ALM) to a healthy dietary plan might help improve long-term glycaemic status.

Why this matters

  • Lifestyle modifications, including diet and physical activity, are the basis to help improve the diabetic condition and protect against more severe complications.

Key results

  • Both diets did not affect HbA1c, fasting serum glucose, insulin and Homeostasis model assessment-Insulin Resistance values and other cardiovascular risk factors.
  • Although ALM had a better nutritional quality, it only managed to lower circulating nitric oxide compared with National Cholesterol Education Program Step II diet as control (CON).
  • Compared with CON, ALM lowered post-interventional fasting serum glucose and HbA1c by 5.9% (P=.01) and 3.0% (P.04), respectively, among patients with the baseline HbA1c ≤8.
  • Both diets did not change mean total and low-density lipoprotein cholesterol concentrations.

Study design

  • 40 patients with type 2 diabetes mellitus were randomly assigned to receive either CON or ~60 g/d ALM for 12 wk after a 2-wk run-in period.
  • CON provided daily calories from carbohydrate, protein, and fat at 55%, 17% and 28%, respectively.
  • Funding: Almond Board of California; U.S. Department of Agriculture.


  • Small sample size.
  • Study was a controlled feeding trial.
