How many carbs are in pineapple?
Pineapple has 21.6 g of total carbs per 1 cup chunks (165 g) — about 19.3 g net carbs after 2.3 g of fiber. That's 13.1 g of carbs per 100 g, roughly 8% of the 275 g Daily Value.

A cup of pineapple chunks sits in the mid-range of sweet tropical fruit for carbs: about 21.6 g of total carbs in a 1-cup serving (165 g), which is about 19.3 g net carbs once you subtract the 2.3 g of fiber. That’s 13.1 g of carbs per 100 g, for roughly 83 calories a cup — lower than grapes or mango, but still firmly a carbohydrate food. For anyone counting carbs, the fiber takes only a small bite, so net lands a couple of grams under the total.
Why net carbs barely move the number
Net carbs — total carbs minus fiber — is the figure that matters for keto, low-carb and blood-sugar tracking, because fiber is the carbohydrate your body doesn’t turn into glucose. Pineapple offers a little fiber (2.3 g per cup), bringing net carbs to about 19.3 g against the 21.6 g total. The carbs are mostly sugar — about 16.3 g per cup, roughly 76% of the total, a slightly smaller sugar share than mango or grapes but still the bulk of it. That natural sugar is what makes fresh pineapple taste so bright and sweet, and it digests fairly quickly.
How a cup fits a daily budget
In practical terms, pineapple is not a keto or low-carb food. At about 19 g net carbs, one cup can use most of a strict keto allowance (20–50 g net a day) before anything else. It’s a touch friendlier than the sweeter fruits, so a smaller serving — a single ring is around 11 g of carbs — can fit a moderate-carb day more comfortably. Watch canned pineapple packed in syrup, which adds carbs well beyond the fruit itself. Pineapple isn’t “bad”; it’s just dense enough in carbohydrate to count, with only modest fiber to cushion it.
If you want the other side of the macro picture, see protein in pineapple — and for any canned or juiced pineapple, always read the label’s own carb and sugar lines.
Frequently Asked Questions
How many carbs are in a cup of pineapple?
About 21.6 g of total carbohydrate in a 1-cup serving of chunks (165 g), which is 13.1 g per 100 g (USDA FDC 169124). That cup is roughly 83 calories, and the carbs are mostly natural sugar.
What are the net carbs in pineapple?
About 19.3 g net carbs per cup — total carbs (21.6 g) minus fiber (2.3 g). Pineapple has a bit of fiber, but net carbs still land close to the total.
How much of the carbs in pineapple is sugar?
Most of it. A cup has about 16.3 g of sugar out of 21.6 g of total carbs — roughly 76%. The rest is mostly other carbohydrate and a little fiber. It's natural fruit sugar, but it still counts toward your total.
Is pineapple keto or low-carb?
No. At about 19 g net carbs, a single cup of pineapple chunks can use most of a strict keto budget (20–50 g net carbs a day). Pineapple sits mid-range among sweet fruits — lower than grapes, higher than watermelon — but it's still not keto-friendly.
How many carbs are in a pineapple ring?
Roughly 11 g of carbs for a fresh ring. A single slice of fresh pineapple is about 80–85 g, so it carries around 11 g of total carbs (about 10 g net, ~8 g sugar). Canned rings in syrup can have considerably more — check the label.
