You may have heard that pineapple can lead to weight loss. There isn’t a whole lot of evidence to back up that claim, though an animal study published in April 2018 in Food Science and Biotechnology did find that pineapple juice may help decrease fat formation and increase fat breakdown. More studies in humans are needed to confirm that result, though.
You’ll find pineapple offered fresh, frozen, and canned, making it a year-round option for those living in the United States. Canned pineapple is convenient, but be sure to look for an option that’s packed in its own juices, not syrup, says Allison Knott, RDN, a dietitian in New York City. “Fruit naturally contains sugar in the form of fructose, so even the canned fruit in its own juice will have grams of sugar listed on the label,” she says. “However, the syrup is considered added sugar and will increase the total grams of sugar while contributing to added sugar intake for the day.”
There are also plenty of ways to enjoy this juicy yellow fruit. You can grill slices and serve them with meat or as a tasty side, or you can toss frozen chunks into a smoothie. You can also, of course, snack on bite-sized pieces. No matter how you prefer to eat it, you’ll want to begin incorporating pineapple into your diet if you haven’t already. Here are eight reasons why.
Along with calcium, the trace mineral manganese is essential for maintaining strong bones, according to the University of Rochester Medical Center. Pineapple is one of the top food sources of the mineral, according to Oregon State University — a single cup of pineapple contains about 76 percent of the recommended daily value of manganese. Manganese may help stave off osteoporosis and helps improve overall bone and mineral density, according to Oregon State University. Be careful not to overdo it, though — manganese intake can be dangerous and may increase the risk of cognitive disorders if you consume more than 11 mg per day, according to a study published in The Open Orthopaedics Journal. But don’t fret: It’d be difficult to reach those levels because ½ cup pineapple has less than 1 mg manganese, Andrews says.
Pineapple is more than just a delicious tropical fruit — it offers significant health benefits as well. In fact, it’s been used in folk medicine since ancient times, according to a study published in September 2016 in Biomedical Reports. It’s native to the Americas and is also grown in tropical climates around the world, according to the National Center for Complementary and Integrative Health (NCCIH).
Even if it doesn’t have a significant effect on your metabolism, it’s a good snack choice because it (and other fruits) is low in calories, high in important vitamins and minerals, and does not include saturated fats or trans fats, Andrews says. “There is no specific fruit or vegetable that directly causes weight loss, but they’ll help fill you up without packing in calories,” Andrews says. “So people tend to eat fewer calories overall if they consume several cups of fruits and vegetables each day as part of a well-balanced diet.”
According to a study published in June 2014 in Molecules , pineapple is a great source of antioxidants, specifically phenolics, flavonoids, and vitamin C. “Antioxidants are compounds in food that may help fight inflammation and free radicals in the body,” Knott says. According to the NCCIH, free radicals are molecules that can cause cellular damage and lead to health issues, including heart disease, type 2 diabetes, Alzheimer’s disease, and eye problems. Filling up on antioxidant-rich foods like pineapple can play a role in countering those risks.
Pineapple contains bromelain, which is a mix of enzymes that studies show can reduce inflammation and nasal swelling, and also aid in the healing of wounds and burns, according to the NCCIH. It’s also been linked to helping improve digestion and has historically been used in Central and South American countries to treat digestive disorders. A study published in Biotechnology Research International found that the bromelain in pineapple may help reduce the effects of diarrhea.
“The standout nutrient in pineapple is vitamin C, which supports the immune system and provides antioxidant benefits,” says Jackie Newgent, RDN, a New York City–based culinary nutritionist and the author of The All-Natural Diabetes Cookbook. One cup of pineapple contains 78.9 milligrams (mg) of vitamin C, according to the U.S. Department of Agriculture (USDA). That’s more than the recommended dietary allowance for adult women (which is 75 mg per day) and close to the recommendation for men (90 mg per day), according to MedlinePlus. Vitamin C is important because it encourages growth and healing around the body and plays a role in everything from wound repair to iron absorption.
Pineapple is more than just a delicious tropical fruit. It has significant health benefits, too, like boosting immunity, potentially fighting cancer, helping with weight loss, and strengthening your bones. We dive into the scientific research here!
