Medical Properties of Pineapple Juice

By Nicki Wolf

Pineapple juice imparts a sweet taste and serves as an option for drinking plain or mixed with other juices. Its medical properties make it a good choice for a variety of health conditions and injuries, although compounds in this juice can interact with some antibiotics. Always consult your health care provider before taking pineapple juice for a medical problem.

Benefits Colitis Patients

Drinking pineapple juice may impart some medical benefits for people who suffer from colitis. This is a condition marked by inflammation of your large intestine. It can trigger abdominal pain and bloating, diarrhea, gas and dehydration. A study published in the December 2010 issue of “Inflammatory Bowel Diseases” indicates that consumption of fresh or frozen pineapple juice may decrease colon swelling due to an enzyme known as bromelain in the fruit. Researchers note that bromelain extract worked more effectively than this juice, but pineapple juice still provided benefits. This study was on mice, so there is a need for human studies to confirm these findings.

Reduces Cholesterol

Include pineapple juice in your diet, and you may naturally reduce the amount of cholesterol in your bloodstream. Research available in the December 2005 edition of “Medical Science Monitor” studied the effect of pineapple and other fruit juices on plasma lipids. Researchers discovered that rats that consumed pineapple juice over a three-hour period experienced a decrease in lipoprotein particles, compounds that carry fat through the blood, and increased metabolism, activities that lower cholesterol levels. As this was an animal study, human studies are required.

Speeds Healing of Tissue Injuries

The next time you have an injury to your tendons, ligaments or other soft tissues, consider drinking pineapple juice. Evidence presented in the April 2011 “Journal of Medicinal Food” reveals that the bromelain in this juice slightly increased the quantity of tendon cells after a crush injury to the Achilles heel in rat models; it also decreased the levels of malondialdehyde, a compound that may cause mutations in tissues. In doing so, pineapple juice contributed to healing in the early stages of an injury, but human studies need to be undertaken.

Contributes to Male Fertility

Pineapple juice’s high manganese content means it is a good choice for boosting fertility through sperm quality. A 1-cup serving of this juice provides 1.3 mg of manganese; the daily-recommended intake for men is 2.3 mg each day. The July-August 2009 issue of “Oxidative Medicine and Cellular Longevity” features a study from Indian researchers, which correlates manganese consumption in pineapple juice and other foods with increased sperm movement. It also protected sperm during freezing for storage, which can raise your chances of conception.
