Eating too many pineapples may cause these side-effects

Pineapples are really very strange things. It would probably be reasonably easy to write a whole book, albeit a small one, containing things that most people don’t know about the spiky topped fruit.

With its rough and textured skin and a crown of spiky green leaves, the pineapple doesn't appear to be a very appealing fruit from the outside. But once you cut the citrus fruit open, it presents a vibrant yellow, juicy flesh with a sweet flavour and delicious aroma. Although the fruit is bursting with healthy nutrition, too much pineapple can produce unpleasant side effects. Following are the serious side-effects of pineapple.
Side-effects of Pineapple


Consumption of pineapples can lead to allergic reactions in a few people. Pineapple has ‘meat-tenderizing’ properties. And these are what cause the fruit to trigger allergic reactions. Mostly these reactions would resolve within a few hours by themselves. But if not, then a medical practitioner should be consulted immediately. Excessive tenderness or swelling on the lips, a tingling sensation in the throat are the symptoms of allergy caused by pineapple.

Blood sugar levels

Pineapples have been found to heighten blood sugar levels. This obviously does pose complications. Pineapples are one of those fruits whose natural sugars are very high. And because of this, they elevate blood sugar levels in our body. Most fruits contain carbohydrates and these can also raise the blood sugar levels. ½ cup of pineapple has 15 grams of carbohydrates. You could experience symptoms like headaches, increased thirst and frequent urination.

Eating Pineapple

Bromelain reactions

Bromelain is an enzyme found in the pineapple juice and stem. This enzyme has been found to cause reactions in our bodies when we consume pineapple. Bromelain has the ability to increase the number of certain antibiotics absorbed by the body. And when bromelain is consumed with blood-thinners, it can increase the risk of bleeding. Nausea, diarrhea, and indigestion are the symptoms of bromelain reactions.

Drug interactions

Pineapple might even interfere or interact with certain types of medications or drugs. This might lead to heightened side effects and other problems. When a fresh pineapple is combined with certain antibiotics like amoxicillin and tetracycline, it might lead to an increase in the side effects caused by these antibiotics. The symptoms of amoxicillin include chest pain, bloody nose, chills, fever, dizziness etc.Tooth Damage

Tooth damage

Though pineapple is a healthy and delicious fruit, it can cause desensitization of teeth or tooth decay. Fruits like pineapple which are highly acidic in nature initiate a chemical process in the mouth when consumed. This softens the enamel and leads to tooth decay. Tooth pain and extreme sensitivity when taking hot or cold foods are experienced when tooth damage occurs because of eating pineapple.

Oral allergy syndrome

Oral allergy syndrome is nothing but an allergy to airborne particles like dust and pollen. This phenomenon occurs when the immune system in our body confuses the protein in pineapple with pollen or any other allergen. As a result of this, reactions occur within the body. You could suffer irritation or itching on the tongue for some time after consuming a pineapple.

They say no human being is perfect. Probably the same applies to fruits too. Depending upon the health conditions one has, some fruits might be desirable and healthy and some might be not.

Though we don’t mean to say pineapples are ‘bad’ or ‘poisonous’, they do have their own set of side effects and should be consumed in moderation.
