When I visited Indonesia earlier this year to support a partner prenatal clinic, I noticed something interesting — papaya was everywhere. It showed up in smoothies, salads, desserts, and breakfast plates. It’s an essential part of many tropical diets.

But during those conversations with mums-to-be, I kept hearing the same question:

“Is papaya safe to eat during pregnancy?”

It’s a myth that has persisted across generations, and today, we’re breaking it down — where the belief comes from, what science says, and how to safely enjoy papaya as part of a healthy pregnancy diet.

Where Did the Papaya Myth Come From?

In several parts of Asia, women have long been advised to avoid papaya during pregnancy, especially in the early stages. This concern stems mainly from unripe or semi-ripe papaya, which contains a thick white latex sap. This sap is rich in papain, a natural enzyme used to break down proteins.

Papain has a somewhat similar structure to prostaglandins and oxytocin, hormones that can stimulate uterine contractions. Because of this similarity, the theory emerged that large amounts of unripe papaya could trigger contractions or even miscarriage.

But theories aren’t the same as evidence — so what does research actually show?

What the Science Says

Most concerns about papaya come from animal studies, where researchers used extremely high doses of unripe papaya extract — far more than any normal human diet would include.

Importantly:

There is no credible scientific evidence that ripe papaya poses any risk during pregnancy.

Ripe papaya — the soft, orange, sweet variety — contains very low levels of latex compared to its unripe counterpart.

In fact, it’s loaded with nutrients beneficial for mums-to-be:

• Vitamin C

• Folate

• Potassium

• Fibre

• Antioxidants

These nutrients support immune health, digestion, foetal development, and overall pregnancy wellness.

Ripe vs. Unripe Papaya: The Key Difference

Understanding the type of papaya makes all the difference:

Ripe Papaya (Orange, Soft, Sweet)

Safe and highly nutritious during pregnancy.

Unripe Papaya (Green, Firm, Often Used in Savoury Dishes)

Contains more latex and should be avoided during pregnancy as a precaution.

If you’re travelling or ordering pre-cut fruit, the distinction isn’t always obvious. Choose fruit that is fully orange or yellow, without green skin or sticky white sap when cut. If you’re unsure — skip it.

A Cultural Myth With Deep Roots

At the clinic in Indonesia, one mum shared that her grandmother had always warned her never to eat papaya while pregnant. She was shocked to learn that ripe papaya is actually rich in folate, one of the most important nutrients during early pregnancy.

It’s a great reminder that cultural beliefs — even well-meaning ones — can linger long after the science has been updated.

Nutritional Benefits of Ripe Papaya During Pregnancy

Here’s why ripe papaya is worth adding to your pregnancy diet:

1. Rich in Vitamin C

Supports immunity and helps your body absorb iron more effectively.

2. High in Fibre

Can help manage constipation, a common pregnancy complaint.

3. Packed with Antioxidants

Supports placental health and reduces inflammation.

4. Contains Folate

Essential for neural tube development.

What About Papaya Enzyme Supplements?

You might come across papaya enzyme or papain tablets marketed for digestion.
These are not recommended during pregnancy, because isolated papain is much more concentrated than what’s naturally found in ripe fruit and may not be safe.

Safe Ways to Enjoy Papaya During Pregnancy

Here are a few nourishing ways to include ripe papaya in your meals:

• Blend ripe papaya into a smoothie with yoghurt and oats

• Toss it into a fresh fruit salad with pineapple and mango

• Serve it chilled with a squeeze of lime

• Add it to breakfast bowls or oats for extra fibre and colour

Just be sure to wash the fruit before cutting to reduce the risk of bacterial contamination.

The Bottom Line

Papaya isn’t the problem — unripe papaya is.

The latex in green papaya can stimulate contractions in theory, so it’s best avoided. But once the fruit ripens, latex levels drop dramatically, making ripe papaya a safe, delicious, and nutrient-packed choice for mums-to-be.
