The pineapple core, the often-discarded, tough, and fibrous center of the fruit, is a surprisingly nutrient-dense part of the pineapple. While its texture is less palatable than the sweet, juicy flesh, its nutritional profile offers significant health benefits that are worth reconsidering before you toss it in the compost bin. This guide will explore the key nutrients found in the pineapple core, compare them to the flesh, and provide simple ways to incorporate this superfood into your diet.
The Key Nutritional Components of Pineapple Core
Bromelain: The Anti-inflammatory Powerhouse
One of the most notable components of the pineapple core is its high concentration of bromelain, a group of proteolytic (protein-digesting) enzymes. Bromelain has been traditionally used for its therapeutic properties and is found in higher levels in the pineapple core and stem compared to the surrounding flesh. Its health benefits are wide-ranging and supported by research:
- Reduces Inflammation: Research suggests that bromelain can be effective in reducing pain and swelling, especially after injuries or surgery. It works by modulating inflammatory mediators in the body.
- Aids Digestion: As a proteolytic enzyme, bromelain helps break down proteins in the digestive tract, aiding in digestion and absorption.
- Supports Immunity: By influencing immune cell activity, bromelain may play a role in supporting the immune system.
High in Dietary Fiber
The core's toughness comes from its high fiber content. This is a significant health advantage, as fiber is crucial for several bodily functions.
- Maintains Bowel Health: A high-fiber diet, which includes the pineapple core, supports regular bowel movements and helps prevent constipation.
- Regulates Blood Sugar: Fiber helps control blood sugar levels by slowing the absorption of sugar into the bloodstream.
- Lowers Cholesterol: Soluble fiber can help lower cholesterol levels, contributing to improved cardiovascular health.
A Source of Vitamins and Minerals
Beyond bromelain and fiber, the pineapple core provides a respectable amount of other vital nutrients.
- Vitamin C: The core is an excellent source of vitamin C, an antioxidant that helps boost the immune system, promotes collagen production, and aids in iron absorption. Some sources even suggest the core may contain slightly more vitamin C than the flesh.
- Manganese and Copper: These essential minerals support bone health and energy production.
Pineapple Core vs. Pineapple Flesh: A Nutritional Comparison
| Nutrient (per 140g) | Pineapple Core (Approximate) | Pineapple Flesh (Approximate) |
|---|---|---|
| Calories | ~45 kcal | ~70 kcal |
| Carbohydrates | ~18 g | ~22 g |
| Sugar | ~13 g | ~16 g |
| Dietary Fiber | ~2 g | ~2 g |
| Vitamin C | ~90% of DV | ~88% of DV |
| Bromelain | High concentration | Lower concentration |
Note: Nutritional data can vary slightly based on the pineapple's variety and ripeness. The core's major advantage is its higher bromelain concentration.
Practical Ways to Eat the Pineapple Core
Because of its tough, fibrous nature, eating the pineapple core raw might be unappealing for some. However, several methods can make it more palatable and enjoyable.
Make a Nutrient-Packed Smoothie
This is one of the easiest ways to use the core. Simply chop it up and blend it with the pineapple flesh and other fruits. The blender will break down the tough fibers, and the sweetness of the flesh will balance the core's milder flavor.
Create a Refreshing Juice or Tea
Boiling the pineapple core can soften it significantly. You can create a simple tea by simmering chopped core pieces in water. For a more intense flavor, blend the core with water and strain it to create a concentrated juice. This can be used as a base for cocktails, mocktails, or a fruity summer drink.
Grate it Over Salads or Yogurt
If you have a powerful grater, you can grate the raw core to produce a fine crumble. Sprinkle this over fruit salads, oatmeal, or yogurt for added fiber and nutrients without the chewy texture.
Grill or Roast for a Smoky-Sweet Flavor
Grilling or roasting the core can soften it and enhance its natural sweetness. The caramelization process brings out a delicious flavor, making it a great addition to skewers or as a side dish.
Conclusion: The Core of the Matter
The pineapple core is a nutritional goldmine that deserves a place in your diet, not the trash. Its high concentration of bromelain, a powerful anti-inflammatory enzyme, combined with an excellent dose of dietary fiber and vitamin C, makes it a valuable health asset. While its texture requires a different approach to preparation, simple methods like blending, boiling, or grilling can unlock its nutritional potential and help you reduce food waste. So, the next time you slice a pineapple, remember the core—it's a little bit of goodness you won't want to miss.

Potential Side Effects and Considerations
While generally safe, consuming large amounts of bromelain, especially from raw pineapple core, can cause a mild, temporary burning or tingling sensation in the mouth. This is due to the enzyme breaking down proteins in your mouth's protective lining. For individuals taking blood-thinning medications, a health professional should be consulted before significantly increasing bromelain intake, as it can slow blood clotting. Allergies to pineapple or bromelain are rare but possible. As with any dietary change, moderation is key.
What to Look for When Buying Pineapples
To get the most out of your pineapple, consider its ripeness. A ripe pineapple is best for consumption, but an unripe one can have different enzyme properties. For the highest concentration of beneficial enzymes, ensuring the fruit is fresh is important, as canned pineapple has less bromelain due to the heating process. Look for a pineapple with a vibrant color, a sweet aroma at the base, and leaves that pull out easily. The heavier it feels for its size, the juicier it likely is.
