Discover pineapple benefits and how bromelain from the fruit, stem, core and peel is used in supplements, foods and health products.

Pineapple Benefits: Fruit, Core, Peel and Stem

Pineapple is more than a sweet tropical fruit. The entire pineapple plant contains compounds being studied for nutritional, digestive, inflammatory and other health applications.

One of the most interesting is bromelain, a group of protein-digesting enzymes found in both the fruit and stem of pineapple.

That helps explain why pineapple has become an ingredient in supplements, functional foods, topical products and other health products.

Pineapple and Bromelain

Bromelain is the star compound associated with pineapple benefits.

Researchers have studied bromelain for inflammation, sinus symptoms, muscle soreness, digestion, pain and wound care. A systematic review and meta-analysis found evidence suggesting potential benefits for some types of pain and for certain sinus symptoms, although results vary by condition and product.

Bromelain also has an unusual medical application. A purified pineapple-stem enzyme preparation is used professionally to remove dead tissue from certain serious burns. The FDA approved a topical bromelain drug for this purpose in 2022.

Don’t Throw Away the Core

The pineapple core is tougher than the juicy fruit, so many people discard it.

Researchers, however, have investigated the core as a source of bromelain and other bioactive compounds.

Studies examining pineapple-processing waste have found measurable bromelain activity in the core, peel and stem. One study found particularly strong enzyme activity in basal stems, while peel and core extracts also showed activity.

That creates an interesting opportunity for health-product manufacturers.

Instead of using only the edible fruit, researchers can recover valuable compounds from parts that would otherwise become waste. MORE HERE

What About the Peel and Crown?

The peel has also attracted attention.

Researchers have extracted bromelain from pineapple peel, core, crown, fruit and stem. Laboratory studies have investigated antioxidant and antimicrobial properties of these extracts. MORE HERE

The crown is less impressive as a bromelain source in some studies, but pineapple by-products remain an active area of research.

This is important because the pineapple industry generates large amounts of peel, core and other plant material. Scientists are exploring ways to turn these discarded parts into useful ingredients rather than waste.

Why Are Pineapple Products So Interesting?

Pineapple naturally provides vitamin C, potassium and other nutrients. It also contains polyphenols, flavonoids, carotenoids and other plant compounds.

Bromelain adds another dimension.

Because it breaks down proteins, researchers are studying its potential effects on inflammation and other biological pathways. A recent 2026 review describes promising laboratory and animal findings involving inflammation, oxidative stress and other conditions, but emphasizes that more human research is needed.

That distinction matters.

Food, Supplement or Extract?

Eating fresh pineapple gives you the nutritional benefits of the fruit. Supplements can provide concentrated bromelain, often extracted from the stem.

Those products are not necessarily equivalent.

The amount and activity of bromelain can vary dramatically depending on the pineapple part used, extraction method and processing.

For consumers, the most interesting lesson may be simple: don’t overlook the whole pineapple.

The fruit provides nutrition. The stem provides concentrated enzymes used in commercial products. The core and peel contain compounds researchers are learning to recover.

Pineapple is a good example of how a familiar food can contain far more chemistry than meets the eye.
