Patients with high fasting blood glucose can eat oranges, but should do so in moderation.

Oranges are a fruit with a relatively low glycemic index, meaning they have less impact on blood glucose levels compared to other high-sugar fruits. Therefore, patients with high fasting blood glucose can consume oranges without significantly affecting their blood sugar. However, it is important to control the amount consumed and avoid eating too much at once. It is also recommended that patients eat oranges between meals when their blood glucose levels are relatively stable, which can help better manage blood sugar levels.

In addition to oranges, patients can also choose other fruits with lower sugar content, such as kiwifruit and dragon fruit. These fruits have a minimal impact on blood glucose and are rich in beneficial nutrients such as vitamins and fiber.

For patients with high fasting blood glucose, regular monitoring of blood glucose changes is important. In terms of diet, they should control total calorie and sugar intake, choose low-sugar, high-fiber foods, and plan meal times and eating schedules appropriately.
