Pineapple Glycemic Index

Pineapple has a medium glycemic index, with reported values ranging from about 51 to 66 depending on ripeness and variety. Fresh, less ripe pineapple sits near the lower end; very ripe or juiced pineapple pushes higher. Because sources genuinely vary, we report a range rather than a single value. In practical terms, treat pineapple as a medium-GI fruit that is fine in sensible portions.

Pineapple can fit into a diabetes-friendly diet with portion control. A one-cup serving has a glycemic load of about 10, which is low. It provides vitamin C and manganese. However, it is a sweeter fruit with more sugar than berries or melon, so portion size matters. Avoid dried pineapple and juice. People with diabetes should discuss serving sizes with their care team — this is general nutrition information.

Pineapple has a higher GI than many fruits like apples (GI ~36), oranges (~43), or strawberries (~41), but is similar to or lower than watermelon (~72) or ripe mango (~60). Its glycemic load per serving is moderate. The key difference is that pineapple's sugar is more rapidly absorbed than lower-GI fruits, but the fiber content still provides a meaningful buffer compared to fruit juice.

Pineapple at about 19.5 g net carbs per cup is moderate for low-carb diets. On a moderate low-carb plan (50–100 g net carbs/day), a half-cup portion fits easily. On strict keto (under 20–30 g/day), even a half-cup uses a significant portion of the daily budget. Most keto followers limit pineapple to occasional small servings or use it as a garnish.

Canned pineapple packed in juice has a GI similar to fresh pineapple, though the syrup-packed version adds significant sugar, raising the glycemic load considerably. Canned pineapple packed in its own juice without added sugar is a reasonable alternative to fresh, but the texture change from processing may slightly affect GI. Always choose juice-packed or water-packed over syrup-packed.
