The study sought to compare the effects of either peanut or almond consumption on health in diabetic patients. Twenty-five patients were fed a low-carbohydrate diet for 12 weeks and were placed in one of two groups: The Almond group or the Peanut group. All participants were instructed to consume approximately 2 servings of peanuts or almonds each day. Cardiometabolic measures were taken each week throughout the study.

Key Findings

Key Findings: By the end of the 12 weeks, participants showed significant improvement in various measures for diabetes. However, authors found that almonds were no better than peanuts for improving glucose levels. In fact, peanut consumption improved both fasting blood glucose levels and postprandial glucose levels (glucose levels tested 2 hours after a meal). By the end of the study, there was also no difference in hemoglobin A1c levels (a marker of long-term glucose control) between the Peanut and Almond groups. The authors noted that while nuts are routinely recommended for diabetics for glucose control, it is not always possible for some diabetics to consume tree nuts due to their higher costs. Peanuts are a low-cost option that can help to keep diabetics healthy if consumed daily as part of a balanced diet.
