Pineapples have amazing health benefits that make them very necessary in our diets
Pineapples are a funny-looking fruit with a serious impact on health, and their health and medicinal benefits include their ability to improve respiratory health, cure coughs and colds, improve digestion, help you lose weight, strengthen bones, improve oral health, boost eye health, reduce inflammation, prevent cancer, increase heart health, fight off infections and parasites, improve the immune system, and increase circulation.
Pineapples are a delicious tropical fruit that have been celebrated for centuries not only for their distinct and unique taste, but also for their seemingly miraculous health benefits. Pineapples are eaten fresh, juiced, cooked, and preserved and their leaves are even used for wallpaper and ceiling insulation. They belong to the Bromeliaceae family and are actual a composite fruit made of coalesced berries that grow at the crown of a fruiting tree.
Historically, the most significant grower of pineapples was Hawaii, but they are now cultivated in large quantities in Brazil, the Philippines, and Costa Rica. That being said, the fruit is actually native to Paraguay and Brazil, and possibly parts of the Caribbean. The exact movement of pineapples and the evolution of pineapples as a popular global fruit are still somewhat unknown. It was first brought to Europe and Spain following Christopher Columbus’s return there in 1493.
Its fruiting season run from March until June, and each tree can produce a number of fruits. The name pineapple actually evolved in the 17th century due to its similar structure and appearance to pine cones. Traditionally, they were known as “ananas”. The fruit itself is up to a foot long and is surrounded by thorny spikes, topped with hard, waxy leaves, sometimes up to thirty per fruit. Pineapples and their sweet juice are used and enjoyed around the world, even as a popular flavor in alcoholic drinks, the most famous of which is the tropical drink, the pina colada!
Nutritional Value of Pineapples
Aside from the interesting story and appearance of this fruit, it is also a storehouse of huge health benefits due to its wealth of nutrients, vitamins, and minerals, including potassium, copper, manganese, calcium, magnesium, vitamin C, beta carotene, thiamin, B6, and folate, as well as soluble and insoluble fiber, and bromelain.
Health Benefits of Pineapples
Arthritis Management: One of the most celebrated uses of pineapple in terms of health is its ability to reduce the inflammation of joints and muscles, particularly those associated with arthritis, a truly debilitating disease that affects millions of people around the world. Pineapples contain a relatively rare proteolytic enzyme called bromelain, which is primarily associated with breaking down complex proteins, but it also has serious anti-inflammatory effects, and has been positively correlated with reducing the signs and symptoms of arthritis in many test subjects.
Immune System: A single serving of pineapple has more than 130% of the daily requirement of vitamin-C for human beings, making it one of the richest and most delicious sources of ascorbic acid. Vitamin C is mainly associated with reducing illness and boosting the immune system by stimulating the activity of white blood cells and acting as an antioxidant to defend against the harmful effects of free radicals. Free radicals are dangerous byproducts of cellular metabolism that can damage various organ systems and disrupt function, as well as cause healthy cells to mutate into cancerous ones. The vitamin C content of pineapples defends against this.
Tissue and Cellular Health: One of the commonly overlooked benefits of vitamin C is its essential role in creating collagen. This is partly the reason why it is seen as a healing vitamin, because collagen is the essential protein base of blood vessel walls, skin, organs, and bones. High vitamin C content helps you heal wounds and injuries to the body quickly, along with defending against infections and illness.
Cancer Prevention: In addition to the antioxidant potential of vitamin C in the battle against cancer, pineapples are also rich in various other antioxidants, including vitamin A, beta carotene, bromelain, various flavonoid compounds, and high levels of manganese, which is an important co-factor of superoxide dismutase, an extremely potent free radical scavenger that has been associated with a number of different cancers. Pineapple has directly been related to preventing cancers of the mouth, throat, and breast.
Digestion: Like most fruits, pineapples are a rich source of fiber, but they are special in that they contain both soluble and insoluble fiber. This means that eating a healthy amount of pineapples can protect you from a vast amount of health conditions, including constipation, diarrhea, irritable bowel syndrome, atherosclerosis and blood clotting, as well as blood pressure. Fiber can bulk up stool, which promotes the passage of food through the digestive tract at a normal rate, and also stimulates the release of gastric and digestive juices to help food dissolve. Furthermore, it bulks up loose stool, which helps with diarrhea and IBS. Fiber also strips the blood vessels clean of excess cholesterol and eliminates it from the body, thereby boosting cardiovascular health.Coughs and Colds: The normal immune system boosting power of vitamin C is well known, but that special enzyme, bromelain, is also connected with the reduction of phlegm and mucus build up in the respiratory tracts and sinus cavities. It therefore prevents the illnesses that cause phlegm and mucus build-up, while also treating them by loosening those materials and helping you eliminate them from your body if you’ve already contracted an illness or infection.
Bone Health: Although pineapples are not famous for having a strong calcium content, which most people immediately associate with bone health, it does have an impressive amount of manganese, which is another trace mineral that is essential in the strengthening of bones, as well as their growth and repair. Manganese is the most prominent mineral in pineapple, and a single serving can deliver more than 70% of your daily requirement of this essential mineral.
Oral Health: Along with the antioxidant compounds that protect against oral cancer, pineapples also have astringent properties, which strengthen gums and make sure that your teeth do not become loose. Astringent agents help to tighten up tissues and tone the body so things like tooth loss, hair loss, and muscle weakness or skin loosening does not occur. Pineapples are very powerful astringents and are often prescribed as a natural remedy to fix loosening of teeth or the the retraction of the gums.
Eye Health: Vision is one of the most important senses for human beings, and pineapples have been directly connected to boosting eye health and preventing the age-related deficiencies that so often occur. Macular degeneration affects many elderly people, and beta carotene can help to delay this vision problem. Keeping proper amounts of beta-carotene in your diet from fruits and vegetables is essential if you want to properly see the world well into your old age.
Blood Pressure: Pineapples are a valuable source of many minerals, and potassium is among them. This is one of the most important minerals in our body, and potassium deficiency can result in a wide array of health hazards. One of the most important functions of potassium is as a vasodilator, meaning that it eases the tension and stress of the blood vessels and promotes blood circulation to various parts of the body. When your blood vessels relax, your blood pressure is reduced and the flow of blood is less restricted. This can prevent clots from blocking the flow of blood and reduces the accumulation of plaque in the arteries and vessels. This helps people prevent conditions like atherosclerosis, heart attacks, and strokes. So eat your pineapples for a healthy heart!
Blood Circulation: In a related benefit to the vasodilating potential of potassium, pineapples also provide the body with copper, another essential mineral that functions in a number of enzymatic reactions and compounds in the body. Most notably, copper is a necessary element for the formation of healthy red blood cells. High red blood cell count increases oxygenation to the various organ systems and makes them function at optimal levels. It also increases cognitive abilities and can maintain neural pathways to prevent neural disorders like dementia and Alzheimer’s disease!
A Few Words of Warning: The benefits of eating pineapple are clear from the impressive list of qualities that you just read, but there is always something about foods that should be cautioned against, and pineapples are no exception. The bromelain in pineapples is primarily a meat-tenderizing enzyme, which is why it is so helpful in the digestion of tough foods. This can result in the softening or tenderness of your “meat” as well, meaning that your lips, gums, and tongue might experience some tenderness or sensitivity if you eat too much pineapple. Bromelain is a powerful chemical, as is vitamin C, if taken in excess. Both of these are in high proportions in pineapple, and an “overdose” can lead to vomiting, nausea, diarrhea, headaches, and nausea. Also, bromelain has been known to stimulate menstruation, so pregnant women should avoid excessive pineapple, as the high levels of bromelain can actually lead to a miscarriage in rare cases.
Other than those health concerns, grab one of these spiky tropical fruits and dig in. Your body will thank you for it!
Pineapple: Health Benefits, Risks & Nutrition Facts

Spiny on the outside, sweet on the inside, pineapples are one fantastic fruit. Pineapples are members of the bromeliad family, and one of the few bromeliads to produce edible fruit, according to the biology department at Union County College. The fruit is actually made of many individual berries that fuse together around a central core. Each pineapple scale is an individual berry.
Pineapples’ nutritional benefits are as fascinating as their anatomy. “Pineapples contain high amounts of vitamin C and manganese,” said San Diego-based nutritionist Laura Flores. These tropical treats are also a good way to get important dietary fiber and bromelain (an enzyme).
“As well as having high amounts of manganese, which is important for antioxidant defenses, pineapples also contain high amounts of thiamin, a B vitamin that is involved in energy production,” Flores said.
For all its sweetness, one cup of pineapple chunks contains only 82 calories. Pineapples are also fat-free, cholesterol-free and low in sodium. Not surprisingly, they do contain sugar, with 16 grams per cup.
Here are the nutrition facts for raw pineapple, according to the U.S. Food and Drug Administration, which regulates food labeling through the National Labeling and Education Act:
*Percent Daily Values (%DV) are based on a 2,000 calorie diet.
|Amt per Serving||%DV*||Amt per Serving||%DV*|
|Total Fat 0g||0%||Total Carbohydrate 13g||4%|
|Cholesterol 0mg||0%||Dietary Fiber 1g||4%|
|Sodium 10mg||0%||Sugars 10g|
|Potassium 120mg||3%||Protein 1g|
The nutritional profile for canned pineapple is different from raw pineapple. According to the U.S. Department of Agriculture, canned pineapple in light syrup has 131 calories per cup and 31.88 grams of sugar. It also contains fewer vitamins and minerals. If you do opt for canned pineapple, try to get it with no added sugar or look for a variety that is canned in fruit juice instead of syrup.
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, according to the Linus Pauling Institute at Oregon State University. This makes vitamin C a helpful fighter against problems such as heart disease and joint pain.
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, according to the Linus Pauling Institute. One 1994 study suggested that manganese, along with other trace minerals, may be helpful in preventing osteoporosis in post-menopausal women.
“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,” Flores said.
Like many other fruits and vegetables, pineapple contains dietary fiber, which is essential in keeping you regular and in keeping your intestines healthy, according to the Mayo Clinic. But unlike many other fruits and veggies, pineapple contains significant amounts of bromelain, an enzyme that breaks down protein, possibly helping digestion, according to the American Cancer Society.
“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,” Flores said. A variety of studies have indicated that bromelain may be helpful in treating osteoarthritis, though more research is needed.
Excessive inflammation is often associated with cancer, and according to the Memorial Sloan Kettering Cancer Center, bromelain and other proteolytic enzymes have been shown to increase the survival rates of animals with various tumors. There is not yet, however, clinical evidence to show that such results will happen in humans.
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.
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, according to the University of Maryland Medical Center. So if your cold has you coughing, try some pineapple chunks. Those with allergies may want to consider incorporating pineapple into their diets more regularly to reduce sinus mucus long term.
“Because pineapple is a great meat tenderizer, eating too much can result in tenderness of the mouth, including the lips, tongue and cheeks,” Flores said. “But, [it] should resolve itself within a few hours.” If it does not, or if you experience a rash, hives or breathing difficulties, you should seek a medical help immediately. You could have a pineapple allergy.
Flores pointed out a possible negative to pineapple’s high levels of vitamin C. “Because of the high amount of vitamin C that pineapples contain, consuming large quantities may induce diarrhea, nausea, vomiting, abdominal pain or heart burn,” she said.
Additionally, extremely high amounts of bromelain can cause skin rashes, vomiting, diarrhea, and excessive menstrual bleeding, according to the University of Maryland Medical Center. Bromelain can also interact with some medications. Those taking antibiotics, anticoagulants, blood thinners, anticonvulsants, barbiturates, benzodiazepines, insomnia drugs and tricyclic antidepressants should be careful not to eat too much pineapple.
Eating unripe pineapple or drinking unripe pineapple juice is dangerous, reports the horticulture department at Purdue University. In this state, it is toxic to humans and can lead to severe diarrhea and vomiting. Eating a great deal of pineapple cores can also cause fiber balls to form in the digestive tract.
- The word “pineapple,” derived from the Spanish word piña, was first used in 1398 to refer to a pinecone. This changed about 300 years later, with the word “pinecone” being introduced so pineapple could be used exclusively for the fruit.
- Pineapples were discovered by Europeans in 1493 on the Caribbean island of Guadalupe.
- Early attempts by Europeans to cultivate the fruit failed until they realized that the fruit needs a tropical climate to flourish. By the end of the 16th century, Portuguese and Spanish explorers introduced pineapples into their Asian, African and South Pacific colonies.
- Because pineapples are very perishable, fresh pineapples were a rarity for early American colonists. Glazed, sugar-coated pineapples were a luxurious treat, and fresh pineapple itself became a symbol of prestige and social class.
- Pineapples were first cultivated in Hawaii in the 18th century. Hawaii is the only U.S. state in which they are still grown.
- Other countries that commercially grow pineapples include Thailand, the Philippines, China, Brazil and Mexico.
- It takes almost three years for a pineapple to mature.
- Pineapple canneries use every bit of the pineapple. The skins, core and end portions are used to make a variety of products, including vinegar, alcohol and animal food.
