In November 2018 researchers from the USA published the results of their study to assess the effect of dried apple on regulation of blood glucose, insulin, satiety, and antioxidant levels. Twenty-one healthy, normal-weight individuals were involved in the study. After a 10-hour fast, the individuals were given either a serving of dried apple or a muffin. Blood glucose, insulin, and antioxidant concentrations were measured at 0, 15, 30, 45, 60, 90, and 120 minutes following food intake, and satiety was assessed every 15 minutes for 2 hours. Cognitive tests were administered before and 2 hours after consumption. Results showed that the serving of dried apple produced significantly lower glucose concentrations at the 30-, 45-, 60-, and 120-minute time points, and a significantly lower insulin concentration at 15-minutes when compared to levels following consumption of the muffin. However, there was very little difference in antioxidant status, satiety, and cognitive function.
