Pineapple

Studies in people

• Benefit

  Sleep hormone levels²

  Eating pineapple raised melatonin levels in the blood of healthy men, along with their antioxidant levels.

• Benefit

  Labor and delivery⁴

  In pregnant women, eating pineapple in the third trimester was linked to shorter labor and more vaginal births.

Animal and lab studies only

• Benefit

  Allergy relief⁶

  Pineapple glucosylceramide eaten by mice reduced swelling from an allergic reaction.

Allergies and intolerances

These are about people with an allergy, an intolerance or coeliac disease. The signal is about the ingredient itself, and these are about the person eating it, so the signal does not count them.

• Fruit allergy cross-reactivity³

  In lab tests, about 40% of people with suspected pineapple allergy had antibodies that react to pineapple profilin.

• Allergic reactions to fruit⁵

  In 32 people, eating pineapple sometimes caused itching, rash, stomach pain, vomiting, diarrhea and shock.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
