Bromelain is a group of enzymes found naturally in pineapples and has gained attention for its potential health benefits. While bromelain supplements are available, many people are interested in obtaining this enzyme through their diet. This article explores what foods contain bromelain, its potential benefits, and other sources.
Benefits of Bromelain
Bromelain is often used as a natural remedy for various health issues, although it’s important to note that scientific research supporting all these uses is still emerging.
Relieving Sinusitis
Bromelain may help reduce symptoms of sinusitis and related conditions affecting breathing and nasal passages. A 2016 review suggests bromelain may shorten the duration of sinusitis symptoms in children, improve breathing, and reduce nasal inflammation. A 2006 systematic review also indicates that bromelain, when used with standard medications, can alleviate sinus inflammation.
Treating Osteoarthritis
Bromelain supplements are commonly used to alleviate osteoarthritis symptoms. A 2004 review suggested bromelain is a useful treatment for osteoarthritis, possibly due to its anti-inflammatory properties. However, the National Institutes of Health (NIH) notes that research on bromelain’s effectiveness in treating osteoarthritis is mixed.
Anti-Inflammatory Effects
Research suggests bromelain might benefit individuals with rheumatoid arthritis. Besides reducing nasal inflammation, bromelain may also decrease inflammation throughout the body.

A 2016 review indicated that bromelain could reduce compounds associated with cancer inflammation and tumor growth in cell and animal models. It may also stimulate the immune system to release inflammation-fighting compounds. Bromelain may also reduce transforming growth factor beta, a compound linked to inflammation in rheumatoid arthritis and osteomyelofibrosis. However, further research is needed to understand bromelain’s effects in humans fully.
Anticancer Effects
According to a 2010 review in Cancer Letters, bromelain might have anticancer effects by directly impacting cancer cells, improving inflammation, and boosting the immune system. However, the NIH states that there is currently not enough evidence to support bromelain’s anticancer effects.
Foods High in Bromelain
While bromelain supplements are available, the most natural source is pineapple.
- Pineapple: Pineapple, especially the stem, contains bromelain. Eating pineapple can provide some bromelain, though the concentration might not be as high as in supplements.
It’s important to note that the bromelain content can vary depending on the ripeness and variety of the pineapple.
Other Potential Benefits
Enhancing Digestion
Some individuals use bromelain to relieve stomach upset and digestive disorder symptoms. Its anti-inflammatory properties make it an adjunct therapy for inflammatory bowel disorders. Animal studies suggest bromelain may reduce the effects of bacteria like Escherichia coli and Vibrio cholera, which cause diarrhea. However, the NIH states there isn’t enough evidence to support using bromelain to aid digestion.
Weight Loss
Some supplement manufacturers market bromelain as a weight loss aid, claiming it speeds up fat digestion. However, there is limited research to support this claim.
Conclusion
While bromelain offers potential health benefits like reducing inflammation and relieving sinusitis and osteoarthritis symptoms, more research is needed to confirm these effects. Pineapples are the primary food source of bromelain, providing a natural way to incorporate this enzyme into your diet. Consider adding pineapple to your diet to potentially benefit from its bromelain content. Always consult with a healthcare professional before using bromelain supplements, especially if you have existing health conditions or are taking medications.
