How many carbs are in pineapple?
A standard serving of raw pineapple (140g, about one cup of chunks) has about 20g of carbohydrate and 18g of net carbs. It is one of the higher-carb fruits by serving size.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 serving, chunks (140g) | 19.7g | 1.3g | 18.4g |
| 100 grams | 14.1g | 0.9g | 13.2g |
Net carbs
One serving of raw pineapple has about 18g of net carbs, which is total carbs (20g) minus fiber (1g). Pineapple is relatively low in fiber compared with many other fruits, so total and net carbs are close together. See the net carbs guide.
Glycemic index of pineapple
The glycemic index of pineapple is about 59. Pineapple sits in the medium glycemic index range. Its natural sugar is mostly sucrose, which digests faster than the fructose-dominant profile in many other fruits. Riper pineapple has more free sugar and a somewhat higher GI.
For diabetes
Pineapple has a medium GI of 59 and 20g of total carbs per serving, making it a fruit that requires planning rather than one to eat freely. The low fiber content means the glucose rise is not substantially buffered. A smaller portion of about half a cup (70g, around 10g of carbs) fits more easily into a meal. Pair with protein or a fat source to slow absorption. See the diabetes carb-counting guide.
Keto and low carb
One serving of raw pineapple has about 18g of net carbs, which is close to a full day's keto budget of 20 to 30g. Pineapple does not fit standard keto. A couple of small chunks used as a garnish or in a recipe (around 30g, about 4g net carbs) can occasionally be worked in if you have room.
Good to know
Canned pineapple in syrup carries significantly more carbs than fresh. A half cup of pineapple canned in heavy syrup can reach 25g of carbs or more compared with about 10g for the same size portion of fresh. Pineapple juice is even more concentrated, at roughly 25g of carbs per half cup with nearly no fiber. If you are carb-counting, fresh pineapple is the most predictable form.
