A 240 ml glass of unsweetened pineapple juice contains about 130 kcal and 24 g of natural sugar, plus manganese and potassium. Vitamin C varies widely: unfortified juice has about 11 mg per 100 ml, while many brands add it back to reach 40 mg or more. Bromelain, the enzyme pineapple is known for, is largely inactivated by pasteurisation in packaged juice.
Key facts at a glance
- Energy: about 53 kcal per 100 ml; similar to apple or orange juice.
- Sugar: about 10 g per 100 ml, all natural in 100% juice.
- Manganese is its standout mineral.
- Bromelain survives in fresh juice but little remains after heat treatment.
- Pineapple juice does not induce labour at normal intakes.

Benefits: what holds up
- Hydration and energy — yes, from water and sugar, like any juice.
- Vitamin C — meaningful mainly in fortified juice.
- Bromelain and inflammation — evidence comes from concentrated bromelain supplements, not pasteurised juice.
- Digestion — fresh juice contains active bromelain; packaged juice little.
- Fibre — negligible unless the juice keeps its pulp.
Pineapple juice in pregnancy
The belief that pineapple triggers labour comes from bromelain. The amounts in a glass of juice are far too small to affect the uterus, and packaged juice contains little active enzyme. Pasteurised pineapple juice is a normal part of a pregnancy diet in moderation; its main consideration is sugar.
Choosing pineapple juice
- 100% juice, no added sugar — pineapple is sweet enough on its own.
- With pulp if you want a little fibre and fuller body.
- NFC for the freshest flavour.
- Check vitamin C on the panel if that is why you are buying it.
Simple uses
- Tropical cooler: equal parts pineapple juice and coconut water over ice.
- Marinade: fresh juice tenderises meat thanks to active bromelain; packaged juice less so.
- Smoothie base: with banana and spinach.
