1. Immune system support

Pineapple contains half of the daily-recommended value of vitamin C, according to the FDA. Vitamin C is a primary water-soluble antioxidant that fights cell damage. This makes vitamin C a helpful fighter against problems such as heart disease and joint pain.

2. Bone strength

Pineapple may help you keep standing tall and strong. The fruit contains nearly 75 percent of the daily-recommended value of the mineral manganese, which is essential in developing strong bones and connective tissue. One 1994 study suggested that manganese, along with other trace minerals, may be helpful in preventing osteoporosis in post-menopausal women. 

3.Eye health

Pineapples can help reduce the risk of macular degeneration, a disease that affects the eyes as people age, due in part to its high amount of vitamin C and the antioxidants it contains. 

4. Digestion

Like many other fruits and vegetables, pineapple contains dietary fiber, which is essential in keeping you regular and in keeping your intestines healthy. But unlike many other fruits and veggies, pineapple contains significant amounts of bromelain, an enzyme that breaks down protein, possibly helping digestion.

5. Anti-Inflammatory benefits

Due to a complex mixture of substances that can be extracted from the core of the pineapple, well known as bromelain, pineapples can help reduce severe inflammation ... and can reduce tumor growth. A variety of studies have indicated that bromelain may be helpful in treating osteoarthritis. 

6.Blood clot reduction

Flores noted that because of their bromelain levels, pineapples can help reduce excessive coagulation of the blood. This makes pineapple a good snack for frequent fliers and others at risk for blood clots.

7.Common cold and sinus inflammation

In addition to having lots of vitamin C, pineapple’s bromelain may help reduce mucus in the throat and nose. Those with allergies may want to consider incorporating pineapple into their diets more regularly to reduce sinus mucus long term.
