We investigated the health benefits of consuming 1-2 cups of red raspberries in a group of people who were overweight/obesity and had prediabetes and insulin resistance.

The results showed that when a breakfast meal was consumed with raspberries, less insulin was needed to manage blood sugar compared with a meal with no raspberries. Moreover, when two cups of red raspberries were included in the breakfast meal, blood sugar concentrations were significantly lower compared to consuming breakfast without raspberries.
