Pineapple Allergy Symptoms | Is Pineapple Toxic

I recently started making tropical fruit smoothies at home. I love tropical fruit, and the benefits of these fruits are great. I have only one problem with these tropical chillers, I have a sensitivity to pineapple. This sensitivity to pineapple can be hazardous for me if I have too much pineapple. It’s effects are minimal when consumed in moderation.

The side effects that I experience are:

  • Swollen Lips (eh, not to bad when the guy you are dating likes full, lush lips)
  • Tingly tongue (not bad when you want to make a group of friends laugh at not being able to say a tongue twister)

These are the “in moderation” side effects that I experience.

In excess the side effects are more severe…photo by - Olga Guryanova

  • Swollen/cracking or blistered lips
  • Tingly/swollen tongue

  • Difficulty breathing/shortness of breath

  • Heart palpitations/racing heartbeat

  • Chest pain

  • Loss of consciousness

  • Giant Hives/blisters covering my whole body (like a sunburn without exposure to the sun)

  • Itchy/scratchy throat/ body from giant hives

When pushed beyond Hives without a Histamine Blocker…Death.

There are several schools of thought on pineapple, and we will cover only two. The first is on the benefits of pineapple. For me, do the benefits out weigh the side effects of eating pineapple?

The second school of though is based on the toxic hazards of pineapple. For me, do these toxic hazards out weigh the benefits of eating pineapple?

I Started My Research With A Simple Search:

I started out on my search for some medical answers to find out more about my symptoms when I eat pineapple. I started my research with a simple search: “Is the heart of a pineapple toxic?”

Why? Recently I watched a video stating that “the heart of a pineapple is cut out because it holds toxins”. — Nate, The Kind Of Random This site does scientific experiments you would not do at home. They do not encourage people to do these experiments, because some experiments are dangerous and should not be done by people at home.

Well, I am finding that it does not matter what part of the pineapple I consume. Why? Long story short:

I worked in a pineapple/banana orchard as a pollinator in Hawaii when I was on summer break as a teenager. When I fell from a crane basket unconscious, I found out that pollinating pineapple/banana trees was not the job for me without industrial strength histamine blockers.

Needless to say, my “pollinator” job was switched, after recovering, to a coconut tree, with industrial strength histamine blockers. I pollinated coconut trees for the rest of that summer.

What are the benefits of pineapple?

The best answer according to Yahoo! ANSWERS is as follows:

“Best Answer: Medicinal Properties of the Pineapple”

“Pineapple contains micro-nutrients that experts believe protects us against cancer and this micro-nutrients also break up blood clots and is beneficial to the heart. The ripe pineapple has diuretic properties. Pineapple juices also kills intestinal worms. It also relieves intestinal disorders and soothes the bile. Pineapple juice contains chemicals that stimulates the kidneys and aids in removing toxic elements in the body.

Pineapple contains a mixture of enzymes called bromelain. Bromelain blocks the production of Kinins that form when there is inflammation. Test[s] have shown that this blocking property of bromelain in pineapple helps reduce swelling brought about by arthritis, gout, sore throat and acute sinusitis. This also helps accelerate the healing of wounds due to injury or surgery. To help reduce inflammation, eat pineapple in between meals. If eaten during or after meals, the enzymes will be utilized for digesting food.” — “Coyote”

“This fruit is an anti-inflammatory food. It helps suppress inflammation. Both the fruit and its main constituents, an antibacterial enzyme called bromelain, are anti-inflammatory. The use of this fruit has thus been found valuable in preventing arthritis and other rheumatic afflictions. Fresh pineapple juice reduces swelling and inflammation both in osteoarthritis and rheumatoid arthritis. An exclusive diet of fresh pineapple juice for [a] few day[s] and repeated regular intervals will help greatly in relieving symptoms of these diseases,” states “BookLov5”.

“Glorified Rice:

  • 1 cup of cold cooked rice

  • 1/2 cup sugar

  • 1 can crushed pineapple, drained

  • 1/2 teaspoon vanilla

  • 1/2 cup miniature marshmallows

  • 2 tablespoons drained cherries

  • 1 (8 ounce) container whipped topping


  1. mix rice, sugar, pineapple, and vanilla

  2. add marchmallows [marshmallows] and cherries

  3. fold whipped cream into rice” — anonymous author on Yahoo! ANSWERS

“Pineapple contains Trytophan [tryptophan] – which is the precursor to the neurotransmitter Serotonin which is highly influential to our mood and has been implicated in many of the mental health issues.

Notable low Serotonin is linked with depression, hence eating pineapple may increase Trytophan [tryptophan] thus increasing Serotonin.

So in short it may make you feel happier on some level.

There are other health benefits too – like all fruits 🙂


Psych hons grad” — by “Pola_pink_ocd”

Another anonymous author continued the thread on Yahoo! ANSWERS stating, “While pineapple may contain some compounds with medicinal activity (such as bromelain, already mentioned), pineapple (per se) is NOT USED medicinally as such. There are no known conditions that are responsive to pineapple.”

“Heartburn. The enzymes in pineapple aid in digestion,” — by “d.a.f.f.y.”

“Pineapple is high in the enzyme ‘bromelain’ which is recommended for healing…especially bruises, but some recommend it when healing after surgery as well,” – by “Kathy_is_a_nurse”.

“Arthritis and high blood pressure,” – by “Dellajoy”.

“If men drink an 8 oz. can a day it can change the way their sperm tastes,” – by “Nursefeelgood”.

Well, I don’t think I have that issue, LOL, or any heartburn. I do, however, have inflammation and get even more inflammation when I have any amount of pineapple. Interesting, my body responds in the opposite way that others’ bodies respond to pineapple. You know, I might even go as far as saying that I would have to definitely use an industrial strength histamine blocker if I exceeded one serving a day for one week.

So, as for inclusion of pineapple every day between meals, I think I’ll pass unless I take 2 Benadryl every four hours on days I exceed one serving. As far as me ever purchasing a fresh pineapple to eat at home, I would have to make arrangements with my local store to purchase the over ripe not sell able pineapple.

While I was on my summer in Hawaii (30 some odd years ago), I found myself in tears — there’s nothing worse than being allergic to something that you love, but it does not love you back. Everybody was indulging on the fresh picked pineapple, and getting them free daily was a perk to the job.

The fresh aromatics of the tropics constantly being consumed in front of me on lunch break while I sat scratching and breaking out with new blisters, was the main reason I found myself in tears. My lips were cracked and bleeding, and no relief other than taking the industrial strength histamine blocker until they moved me to the coconut fields.

Husking coconuts is like tearing housing insulation with your bare hands when your histamine is still in the process of being lowered. I was no longer allowed to be in the crane baskets pollinating. They put me in a juvenile coconut field and the tallest blooms could be reached by a folding ladder. I wasn’t allowed to harvest the coconuts from the trees in fear I’d pass out on the blade from my severe allergic reaction.

I did however experience all other aspects of coconut farming. Everything from pollen collection, intergenous pollination, husking, and milking, and curing coconut.

By the way if you are wondering what “intergenous pollinazation” is, it’s basically pollinating the trees like a human sized bee…dropping pollen from other species of trees from the various farms in the area.

Any how, after inhaling coconut pollen from the coconut tree farm, I noticed that my allergies started easing. My lungs didn’t feel constrained. Despite the remaining sniffles from the pineapple pollen, I began to enjoy my tree pollinating summer.

Since my pineapple sensitivity still exists to the present, I would have to deny a job in the Johnson’s tree farms of Hawaii. I guess I get to stick to the Olive groves my family has in Greece and California.

Now you may be wondering about the scientific thoughts on pineapple versus a peer to peer (p2p) analysis of pineapple. No problem.

According to Jessie Szalay’s contribution to LiveScience.com the U.S. Food and Drug Administration (USFDA) regulate’s food labeling, and has some facts about pineapple.

“Here are the nutrition[al] facts for raw pineapple, according to the U.S. Food and Drug Administration, which regulates food labeling through the National Labeling and Education Act:

Serving size: 1 cup chunks (165 g)

Amount per Serving (%DV*)

*Percent Daily Values (%DV) are based on a 2,000 calorie diet.

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.”

Health benefits – according to Jessie Szalay’s contribution to LiveScience.com

“Immune system support

Pineapple contains all of the recommended daily 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.

Bone strength

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.

Eye health

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.

Anti-Inflammatory benefits

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.”

Health risks

“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. (Well then, I think I may have a pineapple allergy, huh! I think that the hospital in Hawaii noted this long before Flores learned about it.)

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.”

Well, there ya go! I have an allergy not just a sensitivity to pineapple…but I’m still going to eat pineapple in moderation. I have a fail safe…I never eat pineapple without a bottle of Benadryl. I also make sure that I stop eating it when my tongue feels tingly. So, if you have an allergy, don’t do what I do. Consult your doctor and always be aware of what fruit juices contain even small amounts of pineapple, or canned fruit canned in fruit juice.

I believe the second school of thought was covered by Jessie Szalay’s contribution to LiveScience.com.  Thanks for taking the time to read this article.  If you have any questions or comments, please feel free to leave them below.
