Pineapple can flatten your tummy, prevent stomach distention and help your body burn a few extra calories. Pineapple is a nutrient-rich fruit containing vitamin C, manganese, thiamine, copper, fiber and vitamin B-6. Additionally, pineapple contains one very important enzyme: bromelain, which is found in the stem and within the juice of a pineapple. This enzyme metabolizes protein, contributing to a number of health benefits, including a flatter abdomen.

Stomach Bloating

Bromelain digests proteins, which aids in relieving heartburn or an upset stomach. According to the University of Maryland, one animal study revealed that bromelain’s antibacterial properties help combat the bacteria causing diarrhea. Preliminary research shows bromelain to be effective in healing bowel disorders. Relief from stomach conditions can produce a less-bloated abdomen and a slender waist.


Pineapple contains a combination of digestive enzymes that decreases inflammation and edema, as reported by the University of California at San Diego. Pain and inflammation caused by trauma, including surgery, arthritis or sports injury, is reduced when bromelain is consumed. This important enzyme aids in healing and regenerating the digestive lining of the stomach. Belly fat can be mistaken for water retention and stomach distention from inflammation of the bowels. Pineapple helps ease this inflammation resulting in a flatter, slimmer look.

Fat Burning

According to Clayton College of Natural Health, freshly juiced pineapple may help burn fat. Bromelain can work in conjunction with other enzymes, such as lipase, an enzyme that helps digest fats. According to Purdue University, bromelain is thought to aid in appetite inhibition and enhance fat excretion. Additionally, pineapple is a catabolic food, meaning that your body expends more calories digesting the fruit than the number of calories the fruit contains. This results in an overall calorie deficit.


Overall, pineapple is a very safe food. However, juice from unripe pineapples may cause vomiting. Allergic reactions may occur among those who have allergies to honeybee venom or olive tree pollen. Bromelain may overstimulate anticoagulant drugs. Talk to your physician about bromelain consumption if you are taking a blood thinner. Consuming more than two to three servings of pineapple per day among pregnant women has not been researched thoroughly to conclude whether bromelain is safe for expectant or breast-feeding mothers.
