The power of bromelain

Bromelain is what makes pineapple truly special – it’s a complex of protein-digesting enzymes found mainly in the stem and core.

What is bromelain?

Bromelain breaks down proteins into smaller peptides and amino acids. This unique enzyme complex isn’t common in other fruits.

How bromelain works:

• Helps digest proteins in food
• Reduces inflammation by breaking down inflammatory compounds
• May help thin mucus in respiratory conditions

Recent research published in Nutrients (2024) confirms that bromelain is absorbed from the digestive tract in its active form, allowing it to exert effects throughout the body.

Top health benefits of eating pineapple

Reduces inflammation

Pineapple’s anti-inflammatory benefits include:

Bromelain’s inflammation-fighting mechanism: Bromelain blocks the production of compounds that cause swelling and pain. Studies show it can reduce markers of inflammation like interleukin-1β and tumor necrosis factor-α.

Relief for arthritis: Research in Clinical Rheumatology found bromelain supplements reduced pain and stiffness in people with osteoarthritis. It may also help with rheumatoid arthritis by moderating immune response.

Reducing swelling and bruising: Studies show bromelain can speed recovery after surgery or injury by reducing swelling, bruising, and pain.

Aids digestion and promotes gut health

Pineapple can improve your digestive health through:

Bromelain’s protein breakdown: Bromelain helps break down large protein molecules into smaller, more easily absorbed peptides. This can ease digestive issues, particularly after heavy protein meals.

Fiber content: With 2.3g of fiber per cup, pineapple supports regular bowel movements and feeds beneficial gut bacteria.

Potential prebiotic effects: The fiber in pineapple may act as a prebiotic, nourishing beneficial gut bacteria that support digestive and overall health.

Boosts immune system function

Pineapple strengthens your immune defenses through:

High vitamin C content: The high concentration of vitamin C (79mg per cup) enhances the production and function of white blood cells, your body’s main defense against infections.

Bromelain’s immunomodulatory effects: Research published in Cellular Immunology suggests bromelain can regulate immune response, potentially helping your body fight illness more effectively.

Pineapple can give you healthier skin through:

Vitamin C for collagen production: The high vitamin C content boosts collagen production, improving skin elasticity and promoting wound healing.

Antioxidant protection: Pineapple’s antioxidants help shield skin from UV damage and environmental stressors that can lead to premature aging.

Bromelain for wound healing: Some studies suggest bromelain may help reduce inflammation and promote healing of skin wounds and burns.

Pineapple: fresh, canned, or juice – what’s the difference?

Fresh pineapple

• Contains the highest levels of bromelain
• Provides the most nutrients and fiber
• Has no added sugars or preservatives
• Retains all enzymes intact

Canned pineapple

• Heat processing destroys most bromelain
• Still contains good amounts of vitamin C and manganese
• Look for “in own juice” rather than heavy syrup to avoid added sugars
• Convenient and has a longer shelf life

Pineapple juice

• Contains concentrated natural sugars (about 25g per cup)
• Has little to no fiber
• Commercial processing typically destroys bromelain
• Fresh-pressed juice retains more nutrients
• Should be consumed in moderation (4-6 oz serving) due to sugar content

How to choose, store, and cut a pineapple

Selecting a ripe pineapple

• Look: Choose a pineapple with fresh, green leaves and a golden-yellow color (some green is okay). Avoid those with dark spots or moldy areas.
• Smell: The base should have a sweet, fruity aroma. No smell means it’s not ripe enough.
• Feel: It should yield slightly to pressure but not be soft or mushy.
• Weight: Pick a pineapple that feels heavy for its size, indicating juiciness.

Proper storage

• Whole pineapple: Store at room temperature if eating within 2-3 days. Refrigerate (in a perforated plastic bag) for up to 5 days.
• Cut pineapple: Store in an airtight container in the refrigerator for up to 5-7 days.
• Freezing: Cut into chunks and freeze in a single layer, then transfer to freezer bags (good for up to 6 months).

Cutting a pineapple: step-by-step

1. Cut off the top and bottom to create flat surfaces.
2. Stand the pineapple on one flat end and slice downward to remove the skin, cutting deep enough to remove the “eyes.”
3. Cut the pineapple in half lengthwise, then into quarters.
4. Slice off the tough core from each quarter.
5. Cut into chunks or slices as needed.
