Pineapple Juice and Constipation

More than 4 million Americans face routine constipation, according to the National Digestive Diseases Information Clearinghouse, which involves infrequent or difficult-to-pass stools. Common causes include a low-fiber diet, dehydration, certain medications, inactivity and ignoring bowel movement urges. Drinking pineapple juice is a potential natural remedy for constipation. If your symptoms are severe, long-lasting or unchanged by your own efforts, seek medical attention.


One cup of unsweetened pineapple juice provides 0.5 grams of fiber and 8 ounces of fluid 1. The University of Maryland Medical Center recommends drinking at least 8 cups, or 64 ounces, of fluid and 20 to 35 grams of fiber per day for constipation relief 2. The natural plant enzymes in pineapple juice are also believed to play a role in improved bowel function.
