Yes, a diabetic can eat oranges, but they should do so in moderation as part of a balanced diet. Oranges are a good source of vitamin C, fiber, and other nutrients, but they also contain natural sugars, which can cause a spike in blood sugar levels.
Diabetics need to manage their blood sugar levels carefully to avoid complications, so it's important to keep track of how many carbohydrates they consume from all sources, including fruits like oranges.
It's generally recommended that diabetics limit their fruit intake to 2-3 servings per day and choose fruits that are low in sugar, such as berries, cherries, and melons. Oranges can be a part of a healthy diet for diabetics, but they should be eaten in moderation and as part of a well-balanced meal plan.
