Pineapple is the tropical fruit with a party trick: alongside a generous hit of vitamin C, it contains bromelain, a group of enzymes that actually digest protein, which is why fresh pineapple can make your tongue tingle. That mix of antioxidants and active enzymes is why pineapple appears in research on immune support, the body’s anti-inflammatory response and digestion.

Why pineapple is good for you
Pineapple is a strong source of vitamin C, the antioxidant your body relies on to support immune cells and build collagen for skin and connective tissue. It is also one of the better fruit sources of manganese, a trace mineral involved in bone formation and antioxidant enzymes. Its signature compound is bromelain, the protein-digesting enzyme studied for its anti-inflammatory effects and traditionally used to tenderise meat.
Bromelain is concentrated in the core and stem and is broken down by heat, so fresh or lightly prepared pineapple keeps the enzyme active while cooked or tinned pineapple does not.
Pineapple nutrition at a glance
The full breakdown is in the nutrition label above. In short, pineapple is a juicy, naturally sweet fruit whose sugars arrive packaged with water, fibre and vitamin C, so it is refreshing without being heavy. Tinned pineapple in syrup carries added sugar and loses the bromelain, so fresh or tinned-in-juice is the better pick. As with any sweet fruit, a sensible portion suits anyone watching their blood sugar.
How to pick, store and eat pineapple
A ripe pineapple smells sweet and fragrant at the base and gives slightly when pressed, with fresh green leaves; pineapples do not get sweeter once picked, so choose by smell rather than hoping it will ripen. Keep a whole one at room temperature for a day or two, then refrigerate once cut. Slice off the top and base, cut away the skin and eyes, and core it before chunking. Pineapple is delicious with Greek yoghurt or alongside cottage cheese for a classic combination.
Common questions
Why does pineapple hurt my tongue? The bromelain enzyme in fresh pineapple breaks down proteins, including those on the surface of your tongue, which causes that prickly, tingling feeling. It is harmless and settles quickly, and is reduced in cooked or tinned pineapple.
Is pineapple high in sugar? Pineapple is naturally sweet, but its sugars come with water, fibre and vitamin C, so a normal portion fits comfortably in a balanced diet. Tinned-in-syrup versions are higher in added sugar than fresh.
