Pineapple juice is a sweet-tart tropical juice with about 50 kcal and 10 g of natural sugar per 100 ml, plus potassium and manganese. Many bottled juices are fortified with vitamin C. Its famous enzyme, bromelain, is largely destroyed by the pasteurisation used for shelf-stable juice, so claims about digestion and inflammation mainly apply to fresh pineapple, not cartons or cans.

What are the real benefits of pineapple juice?
| Claim | Verdict |
|---|---|
| Supports the immune system | Partly true – vitamin C helps normal immune function, especially in fortified juices |
| Aids digestion | Mostly for fresh pineapple; bromelain is inactivated by heat treatment |
| Reduces inflammation / arthritis | Studies use concentrated bromelain supplements, not juice |
| Supports heart health | Provides potassium, but so do many juices; not a treatment |
| Helps eyesight | No – pineapple is not a meaningful source of vitamin A |
| Helps weight loss | No – juice has sugar and almost no fibre |
| Detoxifies the body | No evidence; the liver and kidneys do this |
How much pineapple juice should you drink?
About 150 ml a day is a sensible portion for adults, in line with UK advice on fruit juice. Choose 100% juice with no added sugar, or dilute it with water or sparkling water.
How to use pineapple juice
- Chilled with ice, or mixed half-and-half with coconut water.
- As a smoothie base with banana and yoghurt.
- In marinades (fresh juice tenderises meat thanks to bromelain).
- In mocktails and cocktails such as piña colada.
Who should be careful?
- People with acid reflux or sensitive teeth – the juice is acidic.
- People with pineapple allergy.
- People managing blood sugar – count it as a sugary drink.
- Pregnant women need not avoid it: normal amounts of pineapple or its juice do not trigger labour.
