This study examined the effects of almond consumption on acute glycemic control in adults at risk for diabetes and assessed whether the effects are sustained during 4 weeks of daily almond consumption. There were 5 study arms which entailed consuming 43g of almonds with breakfast or lunch, and as a morning or afternoon snack, or no almonds. At baseline, participants attended a 490‐min acute‐feeding session, were provided with standard meals and almonds, and blood glucose and insulin were measured at designated intervals. They were then instructed to eat almonds daily for the following 4 weeks before repeating the acute‐feeding session. During the initial acute‐feeding session, blood glucose changed significantly (time & interaction effects, P<0.001), but insulin changes did not differ between groups. Incremental AUC (iAUC) showed lower 60‐min postprandial glycemia with almonds eaten as snacks (P<0.05). Similar trends were observed when they were consumed with meals. Repeated consumption of almonds over 4‐weeks did not alter the 490‐min glycemia trends and 60‐min postprandial iAUC, but the statistical significance diminished. Body weight increased after 4 weeks but not differentially between groups. Body fat remained unchanged. Our study suggests that ingesting almonds as a snack may assist in acute glycemic control, and this effect and body weight are minimally affected by prolonged consumption. This study was funded by the Almond Board of California.
