7 Side Effects of Pineapple
After analyzing the nutrient content of pineapple, we can safely say that this tropical delight is an extremely nutritious and beneficial fruit. However, like every coin has a flip side, pineapple has its cons and we will discuss them in detail below:
- Allergic Reactions: Pineapples are rich in digestive enzymes, one special proteolytic enzyme is called bromelain, which means it breaks down proteins. This is why pineapples are known to have ‘meat-tenderizing’ properties as these enzymes can soften muscle fibers. However, this enzyme may trigger allergic reactions that may vary from mild to severe, mainly affecting the skin or digestive system. The most commonly observed symptoms include hives, rashes, itching, and swelling, and some severe reactions may lead to shortness of breath, chronic rhinosinusitis, chest pain, and low blood pressure (3). Pineapple contains another enzyme called profilin that may trigger latex allergies in some individuals (4). These symptoms may resolve by themselves over a few days, but if they aggravate consult a medical practitioner immediately.
- Abdominal Discomfort: Pineapple contains a rich concentration of vitamin C. Researchers have stated that consumption of higher amounts of Vitamin C may induce digestive issues like nausea, abdominal cramps, or heartburn (5). Additionally, increased bromelain can trigger stomach discomfort and allergies causing diarrhea, dizziness, loss of appetite, excessive menstrual bleeding, vomiting, or diarrhea (3).
- Toxicity: You should only consume pineapple that has been well ripened as along with bad taste, unripe pineapple can be highly toxic to humans. There have been several animal studies that reported itchy throat, abdominal pain, severe diarrhea, and vomiting in people after consuming raw pineapples (6).
- Heavy Bleeding: The bromelin enzyme in pineapples has a certain effect on blood clotting which may be due to its proteolytic effects. There have been human studies stating that bromelin offers bleeding risk. Therefore, doctors suggest avoiding pineapples during pregnancy, liver or kidney diseases, and a week before a dental procedure or surgery. Patients who suffer from a blood or bleeding disease must consult a doctor before consuming pineapples and consider it only after starting with medications (3).
- Dental Health Damage: Pineapple contains different enzymes and sugars that may trigger a desensitizing effect on your teeth or lead to their decay. An undoubtedly tasty fruit, pineapple owing to its enzymes bromelain catalase, and polyphenol peroxidase has a high acidity that may leach the outer layers of the teeth through a chemical process slowly over a long period. So, overconsumption of pineapple without practicing proper oral hygiene may indirectly affect the appearance and quality of your teeth (7).
- Increased Blood Sugar Levels: Pineapple contains high amounts of glucose and sucrose, which are simple carbohydrates and do not take too long for the body to digest. Therefore excessive consumption can lead to serious health concerns, especially in pre-diabetic and diabetic patients. This is because it can spike the blood sugar levels and cause complications. Therefore, most diabetic patients are asked to limit pineapple or any kind of fruit as they contain high levels of simple carbohydrates that have the potential to modulate blood sugar levels (8).
- Kidney Issues: Pineapples are a rich source of potassium, a mineral that may pose some health risks to people suffering from chronic kidney disease. The potassium content is filtered out by the kidneys in a healthy individual. However, in patients with kidney issues, their organs are too weak to efficiently drain out excessive potassium which results in Hyperkalemia, the accumulation of high levels of this mineral in blood serum. This condition may range from mild asymptomatic to fatal symptoms such as muscle weakness, paralysis, etc. Therefore, before incorporating pineapple into your diet, be sure to seek advice from your doctor (9).
- Drug Interaction: Pineapple is usually recommended to avoid especially in patients with heart diseases who are on blood thinner medications like warfarin. This is due to the presence of its proteolytic enzyme, Bromelain. Although low in toxicity, its anticoagulant properties may additionally impact the blood’s consistency and ability to form clots which may be risky for patients suffering from blood-related diseases. Therefore, before taking bromelin supplements while you are on blood thinners you must consult a doctor (3).
