The effects of almond consumption in subjects with Type 2 diabetes: differences between men and women

Type 2 diabetes affects approximately 7.3% of Americans, leading to debilitating and life-threatening comorbidities. Estrogen and testosterone levels have been linked to inflammatory and oxidative stress markers, as well as glucose and insulin concentrations. The present study was designed to determine the link between sex differences, glucose control, and inflammation and oxidative stress related to daily almond ingestion among subjects with type 2 diabetes. Subjects were randomized to an intervention group, which received 1.5 oz. almonds daily for 12 weeks, or to the matched control group, which maintained their current diet. No significant differences were found in changes in glucose control in response to ingestion of almonds. However, CRP was significantly reduced by an average of 36.2% in those that received almonds daily (p = 0.017). Although not significant, women randomized to the intervention group appeared to have improvements in insulin resistance compared to women with no dietary change. Results suggest that the addition of almonds to the diet may be an effective intervention for managing inflammation associated with type 2 diabetes. The addition of almonds to the diet is a low cost intervention that is easily implemented into daily lifestyle. Due to the small sample size, additional studies are needed to determine the impact and mechanisms of almond ingestion in subjects with type 2 diabetes.
