Papaya is a tropical fruit widely valued not only for its sweet flavor but also for its impressive nutritional profile and therapeutic properties. Rich in antioxidants, essential vitamins, and important minerals, papaya contributes significantly to overall health and disease prevention. Regular consumption of papaya can help strengthen the immune system, support digestive function, improve vision, reduce cholesterol levels, and promote healthy, radiant skin. In addition, papaya provides generous amounts of vitamins C, E, and A, making it a powerful natural supplement for daily nutrition.

Papaya seeds are equally beneficial and often overlooked. They possess strong medicinal properties, including the ability to eliminate intestinal parasites, combat bacterial infections, and protect kidney health. Beyond fresh fruit consumption, extracts made from papaya fruit, leaves, and seeds have also demonstrated health-enhancing effects. These extracts are rich in bioactive compounds and have been linked to improved blood sugar control in diabetes and potential anticancer activity.

This article reviews scientific findings related to the health benefits of papaya fruit, seeds, and plant extracts.

What Is Papaya (Pawpaw)?

Papaya (Carica papaya) is a large, pear-shaped fruit that thrives in tropical and subtropical climates. In several countries, it is known as pawpaw or papaw. The fruit has a soft, fleshy pulp that ranges in color from yellow to deep orange or reddish hues. Ripe papaya typically has a bright orange color and a flavor resembling sweet melon. Its aroma becomes slightly sweet when ripe; fruit without scent is usually unripe, while overly strong fragrance suggests over-ripeness.

Papaya seeds are located in the gelatinous center of the fruit. These small black seeds have a peppery, slightly bitter taste and are edible. Papaya can be consumed in many forms: fresh, juiced, blended into smoothies, or added to salads using its seeds. A ripe papaya should feel slightly soft to the touch and show a reddish-orange skin tone.

Papaya Nutrition Facts

Papaya is especially rich in vitamin C, making it an excellent addition to a balanced diet. One cup (approximately 140 g) of mashed papaya provides more than 230% of the recommended daily intake of vitamin C. This high vitamin C content supports immune function and helps reduce oxidative stress.

Papaya is also a valuable source of vitamin A, helping to prevent deficiency and maintain eye health and skin integrity. Together, vitamins A and C act as powerful antioxidants. Historically referred to as the “fruit of the angels,” papaya helps neutralize free radicals—molecules linked to aging, cancer, and cardiovascular disease.

In terms of calories, 100 g of papaya contains about 43 calories. A small papaya (157 g) provides roughly 68 calories, while a large papaya (781 g) contains about 336 calories.

According to nutritional data, 100 g of papaya supplies:

• 60 mg vitamin C

• 950 IU vitamin A (22% RDI)

• 37 mcg folate (10% RDI)

• 24 mg calcium

• 257 mg potassium

• 10 mg magnesium

• 25 mg omega-3 fatty acids

• 7 g dietary fiber (7% RDI)

Papaya also contains important bioactive compounds such as papain, a digestive enzyme known for its anti-inflammatory and anticancer potential. Papaya seeds exhibit antiparasitic effects and may inhibit tumor growth.

Benefits of Papaya

Improves Digestion

Papaya supports digestive health due to its fiber content and papain enzyme, which assists in breaking down proteins. Studies involving papaya extract supplementation showed reduced symptoms of bloating, heartburn, gas, and constipation. Fiber also promotes bowel regularity and gut health.

Rich in Antioxidants

Papaya contains carotenoids such as beta-carotene and lycopene, which protect against oxidative stress. Research indicates that carotenoids from papaya are more easily absorbed than those from carrots or tomatoes. These compounds contribute to reduced risk of chronic disease and improved eye health.

Strengthens Immune Function

Papaya consumption has been shown to increase white blood cell activity and levels of glutathione, an important antioxidant that strengthens immune defenses. Regular intake can help the body fight infections and reduce inflammation.

Anti-Inflammatory Properties

Papaya stimulates cells with anti-inflammatory effects and reduces markers of inflammation. Diets rich in papaya and other carotenoid-containing fruits may lower the risk of arthritis, heart disease, and metabolic disorders.

Supports Heart Health

Lycopene and other antioxidants in papaya protect blood vessels and reduce blood pressure. Studies suggest papaya juice and extracts improve circulation and reduce oxidative stress, lowering the risk of cardiovascular disease.

Enhances Skin Health

Vitamins A, C, and E in papaya promote collagen production and skin elasticity. Research shows fermented papaya extract improves hydration, reduces wrinkles, and protects against premature aging caused by UV exposure.

Accelerates Wound Healing

Papaya contains papain and chymopapain, enzymes used in medical burn treatments. Its antibacterial properties also help prevent wound infections and promote faster healing of ulcers and burns.

Strengthens Bones

Papaya contributes to bone density by supplying antioxidants and minerals that reduce inflammation in joints and support calcium absorption. Diets high in fruit intake have been linked to lower osteoporosis risk.

Protects Eyesight

Papaya provides lutein, zeaxanthin, beta-carotene, and vitamin A, which help prevent macular degeneration and age-related vision loss.

Helps Regulate Diabetes

Papaya leaf extract has been shown to lower blood glucose and cholesterol levels while improving liver and pancreas function.

Boosts Red Blood Cell Production

Papaya leaf extract may increase platelet and red blood cell counts, making it potentially useful in treating anemia-related conditions.

Anticancer Potential

Laboratory studies indicate papaya leaf and fruit extracts may inhibit cancer cell growth, particularly breast cancer. Pectin from papaya also shows tumor-suppressing activity. While research is still preliminary, antioxidant-rich diets are widely accepted for cancer prevention.

Benefits of Papaya Seeds

Papaya seeds are rich in protein, healthy fats, calcium, magnesium, and phosphorus. Their peppery taste makes them suitable for salads or smoothies.

Key benefits include:

• Eliminating intestinal parasites

• Treating gastric ulcers by protecting stomach lining

• Fighting bacterial infections such as E. coli and Salmonella

• Protecting kidney function

• Destroying fungal organisms such as Candida albicans

Digestive Enzyme Smoothie Recipe

Ingredients:

• 2 slices pineapple

• ½ papaya, cubed

• 2 tablespoons plain bio yogurt

• ½ lemon (optional)

• 1 sprig mint

Blend all ingredients until smooth. Add water for thinner consistency. This smoothie supports digestion due to bromelain (pineapple enzyme) and papain (papaya enzyme), which break down protein and reduce inflammation.

Side Effects of Eating Papaya

Papaya is generally safe and well tolerated. Allergic reactions are rare but possible, especially to papaya latex. Fermented papaya supplements may lower blood sugar levels, so individuals with diabetes should consult a doctor before use.
