Pineapple And Pregnancy: Health Benefits, Precautions And Risks


Pineapple is a tasty tropical fruit enjoyed by many around the world. However, there are some concerns about whether it is safe to eat pineapple during pregnancy. Pineapple contains an enzyme called bromelain that may soften the cervix and induce contractions. But the risks depend on many factors. This article will examine the safety of pineapple consumption during pregnancy, including recommended serving sizes, benefits, risks, and tips to enjoy this fruit safely.

An Overview Of Pineapple Nutrition

Pineapple is a nutritious fruit full of vitamins, minerals, and antioxidants. It contains vitamin C for immunity, manganese for bone health, thiamin for energy, and bromelain for reducing inflammation.

Pineapple Nutrition

Pineapples also provide fiber for improved digestion. So there are many potential benefits to consuming this fruit in moderation during pregnancy.

Is It Safe To Eat Pineapple During Pregnancy?

Most healthcare providers agree that pineapple is safe in pregnancy when consumed in normal food amounts. Having a few small servings of fresh pineapple or pasteurized juice a couple of times per week is unlikely to cause problems. Issues mainly arise when eating large quantities of raw pineapple or core every day, especially in late pregnancy.

Potential Benefits Of Pineapple In Pregnancy

Here are some of the possible benefits of eating a small serving of pineapple daily during pregnancy:

➜ Vitamin C for maternal and fetal health

➜ Fiber to reduce constipation 

➜ Manganese for bone development 

Anti-inflammatory effects from bromelain

➜ Hydration from high water content

So when consumed carefully, pineapple can be a healthy addition to a well-rounded pregnancy diet.

Potential Risks And Precautions

Consuming very large amounts of pineapple (e.g. several whole pineapples in a day) may raise some safety concerns:

To stay on the safe side, avoid eating the core which contains the highest bromelain content. Also, limit intake to no more than one fresh slice daily in late pregnancy. Canned versions with less active bromelain are considered safe alternatives as well.

Serving Size Recommendations

Here are some general serving size guidelines for pineapple during pregnancy:

First trimester

1-2 medium slices or 3/4 to 1 cup fresh cubes daily is considered safe. Can also have 4-6 ounces of juice.

Second trimester

Up to 1 medium slice or 3/4 cup fresh cubes daily should not pose risks. Limit juice to 4-6 ounces.

Third trimester

Have no more than one small wedge or 1/2 cup cubes per day. Best to choose canned versions. Avoid eating the core.

Talk to your doctor about appropriate pineapple intake for your individual pregnancy. Moderate servings are unlikely to cause problems but eat larger amounts with caution.


While large amounts of pineapple are linked to increased risks, moderate consumption is considered safe for most healthy pregnancies. Small daily servings of fresh, frozen, or canned pineapple provide pregnancy benefits with minimal risks. Avoid eating the core, limit juice, and follow serving sizes based on your trimester. Talk to your doctor about appropriate pineapple intake for your specific pregnancy.


1. Is canned or frozen pineapple safer than fresh during pregnancy

Yes, canned and frozen versions contain less of the active bromelain enzyme so are considered safer options. Make sure canned varieties are pasteurized with no added sugar.

2. What happens if you eat pineapple cores during pregnancy?

The core contains the highest concentration of bromelain. Eating cores daily, especially in late pregnancy, could theoretically help soften or ripen the cervix. Avoid the core to be safe

3. Can drinking pineapple juice induce labor?

Large amounts of raw juice may have mild uterine-stimulating effects. But typical 4-6 ounce servings are considered safe for most pregnant women. Best to limit juice intake as a precaution.

4. Why is pineapple considered more risky in late pregnancy?

Pineapple may have greater effects on the ripening cervix as you get closer to full term. The bromelain is thought to potentially contribute to early labor when consumed regularly in high amounts in the third trimester.

5. Are pineapple smoothies safe during pregnancy?

Yes, as long as you avoid adding large chunks of the core. The blending process helps decrease the potency of bromelain. Limit smoothies to about 3/4 cup of pineapple pieces per serving.
