Pineapple is a popular tropical fruit loved for its sweet-and-sour taste and rich vitamin content. It is packed with vitamin C, antioxidants, and digestive enzymes that offer many health benefits. However, doctors warn that pineapple is not suitable for everyone. For certain groups of people, eating pineapple can actually be harmful and may worsen existing health conditions.

Here are the groups who should absolutely avoid eating pineapple or consume it only under medical advice.

1. People with Stomach Problems

Pineapple contains bromelain and natural acids that can irritate the stomach lining.
Those with:

• gastritis

may experience burning pain, nausea, or worsening symptoms after eating pineapple.

2. People with Allergies

Some individuals are allergic to pineapple and may develop:

Anyone with a history of food allergies should be especially cautious.

4. People Taking Certain Medications

Bromelain can interact with medications such as:

This may increase the risk of bleeding or alter how drugs are absorbed in the body.

5. Pregnant Women (Especially Early Pregnancy)

Eating large amounts of pineapple during early pregnancy may stimulate uterine contractions due to bromelain, potentially increasing the risk of miscarriage. Moderate intake later in pregnancy is generally considered safer but should still be discussed with a doctor.
