It is always refreshing to bite into a cool slice of pineapple on a hot summer day. Even though it does not look so appealing on the outside, its flesh and core contain plenty of vitamins, minerals, fiber, phytonutrients, and antioxidants.1 And since it is a common fruit, you tend to bite into its juicy goodness without much hesitation and second thought, but there is a limit to how much you can eat safely. Eating too many pineapples lead to undesirable side effects. You need to exercise constraint and limit your intake of the fruit regardless of how much you like it or crave it.

Side Effects Of Pineapples

Pineapple can have the following side effects if you give in to your craving or gluttony and indulge in it excessively.


1. It Causes Allergic Reactions In Some Individuals

Pineapple contains an enzyme known as bromelain, which has the ability to digest proteins. When some people consume pineapple, they get mild allergic reactions such as itching and inflammation of the face and tongue.2 Usually, these reactions subside on their own in a few hours, but if they don’t, you should consult a doctor.

Some people can develop asthma and rhinitis as well when they consume the fruit over an extended period of time.3 You have a higher chance of being allergic to pineapple if you are allergic to other substances, such as pollen, latex, wheat, celery, papain, carrot, and fennel. Exercise caution if you are having pineapple for the first time.4


2. It Reacts With Drugs In Your Body

Bromelain interacts with certain drugs in your body due to which you need to be careful when eating pineapple when under medication. It increases the absorption of certain antibiotics like amoxicillin and tetracycline. It also increases your risk of bleeding if you are on blood thinners like warfarin, clopidogrel, and aspirin.

Think twice before eating pineapple if you take sedatives like anti-seizure medicines, barbiturates, benzodiazepines, alcohol, tricyclic antidepressants, and drugs that treat insomnia as bromelain may magnify the effect of these drugs.5 Always consult your doctor if you are planning to include pineapple in your diet.


3. It Sensitizes Your Teeth

The pH of pineapple ranges from 3.3 to 5.2, which means that it is acidic in nature.6 If you consume the fruit over an extended period of time on a regular basis, your enamel gets eroded, resulting in sensitive teeth.7 You should avoid consuming undiluted pineapple juice or biting into the fruit if your teeth are already sensitive. Precaution will prevent the condition of your teeth from becoming worse.

4. It Increases Blood Sugar Levels

If you are diabetic, it is crucial that you consult your doctor before eating pineapple. Just like any other sweet fruit, it contains fructose, a sugar that raises your blood glucose levels, and causes problems.8 Your doctor will know the condition of your health well and will be able to advise you on whether or not you can eat the fruit or how much you can eat. Always stick to the recommended intake to avoid complications.


5. It Causes Diarrhea

Too much of even a good thing is bad. Pineapple contains fiber, which aids digestion, but an excess of the fruit leads to issues like vomiting and diarrhea.9 Drink plenty of water if you suffer from such issues. Visit the doctor if your condition does not improve in a few hours, or if it gets worse. You will be able to prevent these digestive issues if you stick to the recommended daily intake of 1 to 2 cups of the fruit per day.

6. Unripe Pineapple Is Dangerous

One thing you should keep in mind when eating pineapple is that it should be ripe. Smell the bottom of the fruit to get a sense of its sweetness and look for a yellow or golden color on the outside. When you cut open the fruit, its flesh should be yellow, juicy, and sweet. Eating an unripe pineapple or drinking the juice of one is extremely dangerous. it can lead to severe diarrhea and vomiting, which can be very difficult to treat.10 Seek immediate medical attention if you happen to ingest raw pineapple.
