Fructose is a type of sugar found in fruits that can raise blood sugar levels, making it important for diabetics to be mindful of the glycemic index of the fruits they consume. To maintain healthy blood sugar levels, it’s recommended that diabetics choose fruits with low or moderate glycemic indexes. Low glycemic fruits like strawberries and blueberries are ideal, as they have minimal impact on blood sugar. Moderate glycemic fruits, such as cantaloupe, can also be consumed in small portions to avoid sudden blood sugar spikes. High glycemic fruits, like watermelon, should be avoided entirely.
