Calories in Pineapple

How Many Calories Are in Pineapple?

A one-cup serving of fresh pineapple chunks contains about 82 calories. By weight, pineapple comes in at roughly 50 calories per 100 grams, placing it in the lighter-to-moderate range for tropical fruit — below mango and banana, above watermelon and strawberries. A single round slice is about 42 calories.

Pineapple is almost entirely carbohydrate, with no fat and only about 1 gram of protein per cup. Its bright, tangy sweetness comes from natural sugar balanced by fruit acids, and it is one of the few common sources of the digestive enzyme bromelain.

Pineapple Calories by Serving

Serving	Amount	Calories	Carbs (g)	Sugar (g)
One chunk	~15 g	~7	2	1.5
One slice (ring)	~84 g	~42	11	8
Half cup chunks	~83 g	~41	11	8
One cup chunks	~165 g	~82	22	16
100 grams	100 g	~50	13	10

These figures are for fresh pineapple. Canned-in-syrup pineapple and dried pineapple are notably higher because of added or concentrated sugar.

Fresh vs Canned vs Dried Pineapple

Fresh pineapple at about 82 calories per cup is the lightest option. Pineapple canned in its own juice stays close to fresh, but pineapple in heavy syrup can carry 90 to 100 calories per half cup once the sugary liquid is counted. Dried pineapple is the most concentrated by far — often 250 to 350 calories per 100 grams, with many brands adding sugar on top. Canning also destroys most of the bromelain enzyme through heat. For the best calorie-to-nutrition ratio, choose fresh or, if using canned, opt for the juice-packed version and drain it.

Macros and Nutrition in Pineapple

A cup of pineapple provides about 22 grams of carbohydrate, 16 grams of natural sugar, 2.3 grams of fiber and 1 gram of protein, with no fat. Its standout nutrient is vitamin C — a single cup delivers nearly a full day’s worth — alongside manganese, which it supplies in abundance, plus small amounts of vitamin B6 and copper. Pineapple uniquely contains bromelain, a group of enzymes that break down protein and are studied for anti-inflammatory and digestive effects. Its high water content keeps it light and refreshing.

Does Pineapple Fit a Healthy Diet?

Pineapple fits a healthy diet nicely in moderate portions. It is fat-free, hydrating and an outstanding source of vitamin C and manganese, with the bonus of bromelain. Because it sits on the moderate-to-higher end for fruit sugar, a measured cup is wiser than open-ended snacking, and pairing it with a protein like cottage cheese or Greek yogurt slows the sugar’s effect while adding staying power. Fresh or juice-packed canned pineapple is always preferable to syrup-packed or sweetened dried versions.
