Pineapple Juice - How Many Calories?

The pineapple juice reference provides 53 calories per 100 g. A weighed 150 g amount supplies about 80 calories and 14.97 g sugars. It represents packaged juice with added vitamin C; freshly pressed pineapple juice should not be assigned the same vitamin C value.

Dietitian's Tips for Consuming Pineapple Juice

How many calories are in a glass?

A glass needs a defined amount before it can have a calorie value. The USDA cup measure is 250 g juice, supplying about 133 calories and 24.95 g sugars. A weight of 250 g is not automatically a volume of 250 ml. If the carton lists nutrition per 100 ml, calculate from the volume you drink using that label; converting a gram-based table to millilitres requires density.

Adding water to 150 g juice leaves its roughly 80 calories and 14.97 g sugars in the mixture. The drink becomes larger and more dilute. Drinking half of the evenly mixed drink provides half of the juice’s original energy and sugars.

How much vitamin C does it contain?

The reference with added ascorbic acid contains 43.8 mg vitamin C per 100 g, or 65.7 mg per 150 g. A separate USDA record for pineapple juice without added vitamin C reports 10 mg per 100 g. Check the vitamin C line and ingredient list rather than inferring the amount from the words “pineapple juice.”

When comparing with adult daily vitamin C reference amounts, include the 65.7 mg from 150 g juice alongside other foods eaten that day. The figure applies to the fortified reference, not automatically to another drink with the same name.

A reduced-calorie vegetable-and-fruit drink with added vitamin C supplies about 37.7 mg vitamin C and 0.95 g sugars in 150 g. Fortification in both drinks does not establish the same juice content or sugar amount.

What does unsweetened mean?

Unsweetened juice still contains sugars from the fruit. The 150 g reference amount has about 19.31 g carbohydrate and 0.3 g fibre. Fresh pineapple at the same weight contains 2.1 g fibre. Juice therefore does not retain the whole fruit’s fibre content to the same extent.

The 1 L Dimes Active pineapple drink contains beet sugar and is not 100% juice. Its volume label gives 102 kcal and 25.2 g sugar per 200 ml; this unsweetened juice reference cannot stand in for it.

Source note

USDA SR28 entry 09409 is unsweetened canned or bottled pineapple juice with added ascorbic acid. The unfortified comparison uses entry 09273. Nectar, syrup-based drinks and freshly pressed juice are not treated as the same formula.
