In this comprehensive guide, you will discover fascinating details about papaya history, nutrition, health benefits, selection and storage, and culinary uses. Let’s explore some intriguing facts about this tropical superfruit!


A Brief History of Papayas

  • The papaya plant originated in the tropical regions of southern Mexico, Central America, and northern South America.
  • Indigenous people cultivated papayas for centuries before Spanish and Portuguese explorers spread the seeds to other warm climates around the world in the 16th century.
  • Christopher Columbus is said to have called papayas the “fruit of the angels” after encountering them on his voyages.
  • In the 1800s, papayas made their way to India and later spread throughout Southeast Asia, Africa, and other equatorial regions.
  • Hawaii and Florida lead papaya production in the United States. Commercial cultivation began in Hawaii in the 1920s.

Papaya Plant Facts

  • Papaya plants are large herbaceous plants that can grow over 30 feet tall, but they have soft hollow stems and are not woody trees.
  • Separate male and female papaya plants are required for pollination and fruit production. Only the female trees bear edible fruit.
  • The papaya fruit develops on the female plant as a large berry that matures and ripens year-round in tropical climates.
  • Papaya fruits can weigh anywhere from 1 pound to an astounding 20 pounds or more! The current world record is over 31 pounds.

Health Benefits of Papayas

Eating papayas regularly has been linked to many potential wellness advantages. Here are some top health benefits papayas have to offer:

  • Boost immunity: The high vitamin C content supports immune function and fights infection.
  • Aid digestion: Papain, the proteolytic enzyme in papayas, improves digestion and relieves bloating.
  • Reduce inflammation: Antioxidants like lycopene and vitamin C reduce inflammation throughout the body.
  • Protect vision: Vitamins A and C, beta-carotene, and zeaxanthin promote eye health and prevent macular degeneration.
  • Support heart health: Potassium and lycopene reduce oxidative damage to blood vessels and cholesterol levels.
  • Fight cancer: Research indicates papaya extracts may have anti-tumor effects against certain cancers like breast, lung, and pancreatic.
  • Heal wounds: In addition to eating papaya, the leaves have been used topically to clean wounds and ulcers.

As you can see, papayas are packed with nutrients that offer a wide range of wellness perks. Consuming them regularly can enhance your overall health.

Papaya Enzymes: Papain and Chymopapain


Two important enzymes found in papayas that provide health benefits are papain and chymopapain.


  • A proteolytic enzyme that helps break down proteins.
  • Improves digestion by aiding in the breakdown of meat proteins.
  • Used as a meat tenderizer and in some digestive enzyme supplements.
  • Also used in brewing beer to clarify the final product.
  • Applied topically to wounds due to anti-inflammatory effects.


  • An enzyme derived from papain that helps relax and decompress spinal discs.
  • Sometimes injected into discs in minimally invasive spinal procedures.
  • Has a potential pain reduction effect for herniated or slipped discs.

These papaya enzymes offer therapeutic effects both when consumed and used topically or medicinally. More research is needed to determine the full extent of their benefits.

Selecting Ripe Papayas

Choosing perfectly ripe papayas results in the best flavor and sweetness. Here are some tips for picking ripe papayas:

  • Skin color: Ripe papayas turn from green to mostly yellow or orange. Reddish spots indicate ideal ripeness. Avoid fully green fruits.
  • Firmness: Gently press the fruit. Ripe papayas should yield slightly but not feel overly soft or mushy.
  • Aroma: Bring the papaya close to your nose. Look for a sweet, fragrant tropical aroma. Avoid any off-smells.
  • Stem: The stem and surrounding area should be greenish-yellow and feel firm. Dark brown, dried stems signal overripe fruits.
  • Shape: Pick papayas that feel heavy for their size with no major bruises or blemishes.

Storing Papayas

Follow these papaya storage tips:

  • At room temperature, ripe papayas last 2-3 days. Refrigerating extends shelf life up to 5 days.
  • Let refrigerated papayas come to room temp before eating for the best texture and flavor.
  • Allow unripe green papayas to ripen at room temperature until mostly yellow.
  • Place ripening papayas in a paper bag sealed loosely. The ethylene gas released helps them ripen faster. Check daily.
  • Once cut, wrap the leftover papaya tightly in plastic wrap and refrigerate. Use within 2-3 days.
  • Papaya can be frozen for later use in smoothies, salsas, or chutneys. Peel, seed, and cut before freezing.

Potential Side Effects of Papayas

Potential Side Effects of Papayas

For most people, eating papayas is completely safe. However, there are a few potential side effects to be aware of:

  • Allergies: Papayas contain enzymes called chitinases that can cause cross-reactions in people allergic to latex, bananas, avocados, or kiwi. Discontinue use if any itching or swelling occurs.
  • Medications: Papain may increase the absorption of some medications like blood thinners, beta blockers, and certain antibiotics. Consult your doctor first if taking any prescription medicines.
  • Pregnancy: Unripe or semi-ripe papaya is sometimes recommended to be avoided in pregnancy as it may potentially stimulate contractions. Fully ripe papaya is likely safe in moderation.
  • Oral Contraceptives: An enzyme in papaya called myrosinase may interfere with contraceptive pills. More research is needed, but taking precautions if concerned is reasonable.

Outside of these specific concerns, ripe papayas can be enjoyed by most people regularly as part of a healthy diet. Moderation and common sense are key.
