1. Anti-inflammatory properties
Pineapple is the only major dietary source of bromelain. While it’s found in the greatest concentration within the core of the fruit, it is also found throughout the sweet parts and in the juice. According to one study, pineapple can be useful in the treatment of sports injuries, thanks to the anti-inflammatory properties of bromelain.
2. Anticancer agent
Studies show that bromelain has the potential to act as an effective cancer-fighting agent. Specifically, it may work in unison with chemotherapy to suppress the growth of cancer cells. It also contains beta carotene, which can protect against prostate cancer and possibly colon cancer. As far as treatment goes, the National Center for Complimentary and Integrative Medicine says that further research is needed.
3. Heart benefits
The vitamin C in pineapple juice may also help to protect against heart disease. A number of studies — including one from Finland and another from China — show that higher vitamin C intake causes a decrease in the risk of coronary heart disease. Also, like cancer, heart disease risk reduces with a high-fiber diet.
4. Cataract prevention
Vitamin C also plays a crucial role in protecting vision. A recent study showed that higher intake of vitamin C reduces the risk of cataracts, which is cloudiness of the lens that can interfere with vision. The authors even suggest that it should be used as the primary preventive method.
5. Fertility perks
Pineapple juice contains several beneficial vitamins and minerals, including vitamin C, beta carotene, copper, zinc, and folate. Many of these can help boost fertility in both men and women.
