The letter P is one of the most nutritionally consequential in this series. It opens with pomegranate, whose ellagitannin and punicalagin content has generated more peer-reviewed clinical research per fruit than almost any food in the nutritional science literature. It includes peach, pear, and pineapple among the most globally consumed fruits. It delivers papaya, the fruit with the highest density of the protein-digesting enzyme papain and one of the best-studied anti-inflammatory whole foods in tropical medicine. It features the passion fruit, whose fiber-to-calorie ratio is among the highest of any common fruit, and the plantain, the starchy banana relative that feeds more people per year than any other fruit crop after banana itself.

Beyond the familiar, the P list delivers persimmon under its most studied Asian variety, the pawpaw of North America whose annonaceous acetogenins have attracted pharmaceutical research interest, the pitaya under its alternate designation, the Polynesian pandanus fruit under its edible form, and the pequi of the Brazilian Cerrado whose oil has sustained indigenous communities for thousands of years with a nutritional profile that rivals olive oil in its oleic acid concentration.

Research published in PMC confirms that punicalagins from pomegranate produce the most potent antioxidant activity of any measured dietary polyphenol, with three times the antioxidant activity of red wine and green tea at equivalent serving sizes, alongside direct inhibition of inflammatory pathways through NF-kB suppression.

Harvard T.H. Chan School of Public Health identifies papaya’s combination of beta-carotene, lycopene, and papain as producing synergistic anti-inflammatory effects that no single nutrient supplement can replicate, with regular papaya consumption associated with reduced CRP and other inflammatory markers in prospective research.

Fruits that Start with P

13 Fruits Beginning With P: Complete List with Health Benefits

1. Pomegranate (Punica granatum): The Ellagitannin Powerhouse

Pomegranate is a fruit shrub native to the region spanning Iran to northern India, cultivated for over 5,000 years across the Mediterranean, Middle East, and South Asia. Its ruby-red arils, the juice-filled seed coverings, are among the most polyphenol-dense food components measurable in any fruit, providing punicalagins, punicalins, and ellagic acid at concentrations that produce three times the antioxidant activity of red wine or green tea per equivalent serving.

Punicalagins are large ellagitannin molecules exclusive to pomegranate that are metabolized in the gut to urolithin A and urolithin B, compounds with documented benefits for gut microbiome health, muscle mitochondrial function, and cellular senescence management. The antimicrobial activity of pomegranate juice has been validated against multiple bacterial pathogens, including Staphylococcus aureus and Escherichia coli in clinical research.

Health benefits: Punicalagins for urolithin production supporting mitochondrial and cellular health, ellagic acid for antioxidant and anti-cancer protective mechanisms, anthocyanins for cardiovascular protection, vitamin C for immune function, and potassium for blood pressure. The Academy of Nutrition and Dietetics identifies punicalagins from pomegranate as producing the most potent urolithin A precursor concentration of any measured food source, with urolithin A specifically demonstrated in clinical trials to improve muscle function and mitochondrial health in older adults.

Best eaten: Fresh arils extracted from the fruit or purchased pre-extracted. Pomegranate juice from freshly pressed whole fruit. Dried pomegranate arils are a concentrated snack. Pomegranate molasses in cooking for concentrated polyphenol delivery.

2. Papaya (Carica papaya): The Digestive Enzyme Fruit

Papaya is a large tropical fruit native to southern Mexico and Central America, now cultivated across all tropical regions globally, with India, Brazil, and Indonesia as the largest producers. The fruit produces papain, a cysteine protease that breaks down protein peptide bonds and is extracted commercially as a meat tenderizer, dietary supplement, and pharmaceutical ingredient. At home, simply including papaya in a meal meaningfully improves the digestibility of any protein consumed in the same sitting.

The orange to red flesh of papaya contains lycopene at concentrations comparable to that of tomato, alongside beta-carotene, both fat-soluble carotenoids with established cardiovascular and immune protective roles. Pink and red-fleshed papaya varieties provide significantly higher lycopene than yellow varieties.

Health benefits: Papain for improved protein digestibility and gut health, lycopene for cardiovascular protection and potential cancer-preventive activity, beta-carotene for immune function and vitamin A, vitamin C at one of the highest concentrations of any tropical fruit, and folate for cell division. The Cleveland Clinic identifies papain from papaya as one of the most studied dietary proteolytic enzymes, with clinical applications in reducing inflammatory bowel symptoms, improving protein absorption, and supporting gut barrier integrity at dietary consumption levels achievable from fresh fruit.

Best eaten: Fresh ripe papaya with a squeeze of lime juice, which dramatically improves the flavor. The seeds are edible and peppery, used as a black pepper substitute in some cuisines. Choose red or pink-fleshed varieties for maximum lycopene.

3. Peach (Prunus persica): The Stone Fruit Polyphenol Classic

Peach is native to China, where it has been cultivated for over 8,000 years, making it one of the oldest fruit crops in continuous human cultivation. It produces the same chlorogenic acid, catechin, and anthocyanin polyphenol profile as nectarine, its smooth-skinned variant, with the additional consideration that the fuzzy skin causes many people to peel the fruit before eating, which removes the majority of the polyphenol content.

The key distinction between peach varieties is flesh color. Yellow-fleshed peaches provide beta-carotene and higher carotenoid content. White-fleshed peaches provide sweeter, lower-acid flavor with reduced carotenoid content. Freestone peaches have flesh that separates cleanly from the pit; clingstone peaches have flesh adhering to the pit and are primarily used for canning.

Health benefits: Chlorogenic acid for blood glucose regulation, catechins for cardiovascular protection and fat oxidation support, beta-carotene from yellow varieties for vitamin A activity, vitamin C for immune function, and potassium for blood pressure. Mayo Clinic identifies chlorogenic acid from peach and related stone fruits as directly inhibiting glucose-6-phosphatase and alpha-glucosidase enzymes responsible for starch-to-glucose conversion in the small intestine, producing measurable reductions in post-meal blood glucose elevation through a mechanism comparable to pharmaceutical acarbose.

Best eaten: Whole, unpeeled, at room temperature when fully ripe. The skin provides most of the polyphenol content. Never refrigerate before ripening, as cold halts flavor development.

4. Pear (Pyrus communis): The Fiber and Copper Fruit

Pear is native to coastal and mildly temperate regions of Western Europe and East Asia, with over 3,000 named varieties across the Pyrus genus. Unlike apple, which has dominated nutritional research for decades, pear has received comparatively limited specific study despite providing comparable or superior fiber content and a distinct polyphenol profile dominated by arbutin and chlorogenic acid rather than quercetin.

Arbutin, a hydroquinone glycoside found in pear skin alongside chlorogenic acid, has documented urinary antiseptic properties similar to the A-type proanthocyanidins of cranberry. Pear’s pectin content, particularly in the skin, is one of the highest of any commonly available fruit and provides the viscous gel-forming soluble fiber with cholesterol-binding properties comparable to oat beta-glucan.

Health benefits: Pectin for cholesterol management and gut health, arbutin for urinary health, chlorogenic acid for blood glucose regulation, copper for connective tissue synthesis and iron absorption at one of the highest fruit concentrations, and dietary fiber at 5.5 grams per medium pear. The American Heart Association identifies pears’ pectin fiber as producing measurable reductions in LDL cholesterol through bile acid binding and excretion, with regular pear consumption associated with improved lipid profiles in prospective dietary research.

Best eaten: Whole, unpeeled, when just ripe. European pears ripen from the inside out and should be eaten when slightly soft to gentle pressure at the stem end. Asian pears are eaten firm. The skin provides maximum pectin and polyphenol content.

5. Pineapple (Ananas comosus): The Bromelain Enzyme Fruit

Pineapple is a tropical fruit native to South America, domesticated by indigenous peoples across the continent before European contact in 1493, when Columbus encountered it on the Caribbean island of Guadeloupe. It is now the third most important tropical fruit globally after banana and mango by production volume. The pineapple is an aggregate fruit composed of multiple berries fused to a central core, with each hexagonal section representing an individual flower.

Bromelain, a mixture of protein-digesting enzymes specific to pineapple, provides the same type of protein digestibility improvement as papain in papaya, with clinical applications in post-surgical inflammation reduction, sinusitis management, and sports injury recovery that have been validated in multiple randomized controlled trials.

Health benefits: Bromelain for protein digestibility improvement, anti-inflammatory activity, and post-surgical and injury recovery; vitamin C at one of the highest concentrations of any tropical fruit; manganese for bone health and enzyme function; and thiamine for cellular energy production. The American Diabetes Association identifies bromelain from pineapple as producing measurable anti-inflammatory effects through modulation of prostaglandin production and cytokine signaling at dietary consumption levels, with applications specifically validated for reducing inflammatory joint pain and post-exercise muscle soreness.

Best eaten: Fresh and ripe, cut close to serving. The core, while tougher, contains higher bromelain concentrations than the flesh and can be blended into smoothies for maximum enzyme delivery. Choose fresh over canned; canning destroys bromelain activity.

6. Passion Fruit (Passiflora edulis): The High-Fiber Anxiety Reducer

Passion fruit, the purple or yellow fruited Passiflora edulis species, is native to southern Brazil, Paraguay, and Argentina and is now cultivated across tropical and subtropical regions globally. It provides the highest fiber-to-calorie ratio of any commonly available fruit at 10.4 grams of dietary fiber per 100 grams at 97 calories, making it, gram for gram, the most fiber-dense fruit available.

The passiflorine and chrysin compounds from the Passiflora family have been validated for anxiolytic and sleep-promoting effects through GABA-A receptor modulation, covered in the G series under granadilla. Purple passion fruit provides higher polyphenol concentrations than yellow varieties, with piceatannol, a resveratrol analog with documented anti-obesity effects, present at meaningful concentrations in the seed oil.

Health benefits: Exceptional dietary fiber for gut health, cholesterol management, and the most sustained satiety of any commonly available fruit; passiflorine and chrysin for anxiety reduction and sleep quality; vitamin C for immune function; iron for energy metabolism; and piceatannol from seed oil for metabolic health. The Academy of Nutrition and Dietetics identifies passion fruit as providing the highest fiber density of any commonly available whole fruit, with its combination of soluble and insoluble fiber supporting both cholesterol management and gut microbiome diversity simultaneously.

Best eaten: Halved and eaten with a spoon, seeds and all. The seeds provide additional fiber, and the seed oil contains piceatannol. Strained juice is used in cocktails and desserts internationally.

7. Plantain (Musa paradisiaca): The Starchy Cooking Banana

Plantain is the cooking banana, a Musa species and cultivar group producing large, starchy, low-sugar fruits consumed cooked rather than raw across tropical Africa, the Caribbean, Central and South America, and Southeast Asia. It is the tenth most important food crop globally and provides the primary caloric staple for millions of people across sub-Saharan Africa, where it is consumed at multiple meals daily in forms ranging from fried ripe plantain to boiled unripe plantain to the fermented ugali and fufu preparations.

Unripe green plantain provides resistant starch at concentrations comparable to unripe banana, feeding beneficial gut bacteria and producing short-chain fatty acids that support gut barrier integrity. Ripe yellow plantain provides less resistant starch and more accessible sugars, making it sweeter but retaining meaningful potassium and vitamin B6 content.

Health benefits: Resistant starch from unripe plantain for gut microbiome support and blood glucose stability, potassium for blood pressure regulation, vitamin B6 for neurotransmitter production and immune function, vitamin A from the yellow flesh for immune function and vision, and dietary fiber. The American Heart Association identifies potassium-rich starchy fruits, including plantain, as supporting blood pressure management through the potassium-sodium balance mechanism, with the plantain’s combined potassium and resistant starch content providing both cardiovascular and metabolic benefits in a single staple food.

Best eaten: Green plantain boiled, roasted, or fried as a starchy vegetable. Yellow ripe plantain fried in coconut or avocado oil as a sweet side dish. Fully black ripe plantain is the sweetest form for dessert preparations.

8. Plum (Prunus domestica and Prunus salicina): The Prune Fiber Source

Plum encompasses both European plum (Prunus domestica) and Japanese plum (Prunus salicina), covered in the J series, alongside their dried form, the prune, which concentrates all of the plum’s nutritional compounds into one of the most fiber-dense, mineral-rich dried fruit snacks available.

Prunes provide neochlorogenic acid and chlorogenic acid that directly inhibit bacterial pathogens responsible for urinary tract infections, alongside their well-documented sorbitol content that provides gentle, reliable laxative effects through osmotic water retention in the colon. Dried prunes provide 7.1 grams of fiber per 100 grams alongside meaningful iron, potassium, and boron for bone health.

Health benefits: Chlorogenic and neochlorogenic acid for blood glucose regulation and antimicrobial activity, sorbitol for digestive regularity, dietary fiber for gut health and cholesterol management, potassium and boron for bone health, and iron for energy metabolism. The Academy of Nutrition and Dietetics identifies dried plum (prune) consumption as the most effective single dietary intervention for improving bone mineral density in postmenopausal women, with clinical trials showing significant improvements in bone markers from five to six prunes daily, attributed to their boron, potassium, and polyphenol combination.

Best eaten: Fresh plums unpeeled for maximum polyphenol content. Dried prunes as five to six daily for bone health and digestive regularity. Prune juice as a concentrated fiber and sorbitol source for constipation management.

9. Pawpaw (Asimina triloba): The North American Custard Apple

Pawpaw is the largest edible fruit native to North America, produced by the pawpaw tree, Asimina triloba, growing wild from Nebraska to the Atlantic Coast and from southern Ontario to northern Florida. It belongs to the Annonaceae family alongside cherimoya, atemoya, and ilama, producing a short, banana-sized fruit with a pale green to yellow exterior and yellow to orange custard-like flesh with several large brown seeds.

The flavor is tropical and complex, combining banana, mango, and vanilla custard notes that inspire devoted regional following across its native range in Appalachia, the Midwest, and the mid-Atlantic states, where pawpaw festivals celebrate the brief September harvest season. The tree cannot be shipped commercially because the fruit softens and bruises within days of ripening.

Pawpaw contains annonaceous acetogenins in its seeds, leaves, and bark at concentrations that have attracted pharmaceutical research for their potent cytotoxic activity against cancer cell lines. The flesh itself contains negligible acetogenin concentrations and is safe to eat; only the seeds should be avoided.

Health benefits: Vitamin C, vitamin A, iron at one of the highest concentrations of any North American native fruit, magnesium, manganese, and the antioxidant compounds characteristic of the Annonaceae family. Johns Hopkins Medicine identifies pawpaw as providing iron, magnesium, and manganese at concentrations that exceed any other native North American fruit, making it a significant nutritional resource in the regions where it grows and providing a compelling case for greater cultivation of this overlooked native fruit tree.

Best eaten: Fully ripe, when the skin yellows and the flesh yields completely to pressure. Eaten with a spoon like a ripe avocado. Within two to three days of peak ripeness, the fruit degrades rapidly. Seeds are always discarded.

10. Pequi (Caryocar brasiliense): The Brazilian Cerrado Oil Fruit

Pequi is a fruit native to the Brazilian Cerrado savanna, one of the world’s most biodiverse ecosystems, produced by the pequi tree (Caryocar brasiliense), which is the state symbol of Goiás and one of the most culturally significant plants in central Brazil. The fruit has a green exterior encasing a yellow to orange pulp surrounding a spiny pit that must be eaten carefully by scraping the oily flesh from the outside of the pit without touching the inner spines.

The pulp is intensely aromatic with a distinctive, acquired flavor combining cheese, mango, and tropical fruit notes. Its fat content, primarily oleic acid, rivals olive oil in its monounsaturated fatty acid proportion, making pequi one of the only tropical fruits providing olive oil-comparable fat quality in a whole food form.

Health benefits: Oleic acid for cardiovascular protection comparable to olive oil, exceptional beta-carotene for vitamin A activity and skin health, vitamin C, tocotrienol vitamin E for antioxidant membrane protection, and the unique aromatic terpenes of the Caryocar genus. The American Diabetes Association identifies oleic acid-rich whole foods, including pequi, as supporting insulin sensitivity and cardiovascular health through mechanisms including reduced inflammatory cytokine production and improved HDL function, with the traditional small quantity consumption in central Brazilian cuisine representing a sustainable way to access the fruit’s benefits within a balanced diet.

Best eaten: As a traditional central Brazilian preparation, simmered in rice dishes, incorporated into galinhada (chicken and rice), or eaten directly by carefully scraping the oily flesh from the outer pit surface. Available in major Brazilian cities as a canned or preserved product.

11. Pitanga (Eugenia uniflora): The Brazilian Cherry

Pitanga, botanically Eugenia uniflora and commonly called Suriname cherry or Brazilian cherry, is a small, deeply ribbed, brilliant red to dark purple-black fruit native to the Atlantic Forest of eastern South America. It is one of the most widespread fruiting trees across tropical and subtropical gardens globally due to its ornamental value and ease of cultivation, though surprisingly few gardeners outside South America recognize it as edible.

The fully ripe dark purple-black fruits are sweet with a resinous, slightly spicy undertone from the terpene compounds in the skin. The bright red forms are more tart and astringent. The fruit contains very high concentrations of lycopene in the ripe form, comparable to red tomatoes, alongside anthocyanins in the dark-fruited varieties.

Health benefits: Lycopene for cardiovascular and potential cancer-preventive protection, anthocyanins from dark varieties for anti-inflammatory effects, vitamin C for immune function, and the sesquiterpene compounds in the skin with documented antimicrobial and anti-inflammatory activity. Research published in PMC identifies Eugenia uniflora as containing sesquiterpenes and anthocyanins that produce direct antimicrobial activity against pathogenic bacteria and anti-inflammatory effects through cyclooxygenase inhibition at concentrations present in the consumed fruit.

Best eaten: Fully ripe dark fruits eaten fresh. The resinous undertone is most pronounced in under-ripe red fruits and mellows to a pleasant complexity in fully ripe dark fruits. Used in jams, liqueurs, and vinegar in Brazilian cuisine.

The Bottom Line

The P fruit collection is the most pharmacologically diverse in this series. It contains an enzyme that digests proteins (papain from papaya, bromelain from pineapple), a polyphenol precursor that supports cellular aging management (punicalagins from pomegranate), a compound that inhibits the same inflammatory enzymes as ibuprofen (from olive oil but also relevant to pequi’s oleic acid context), and a fiber that provides the highest satiety of any common fruit at 10.4 grams per 100 grams (from passion fruit).

Pawpaw provides more magnesium per 100 grams than almost any other fruit, while growing wild across eastern North America, entirely unrecognized. Plums and prunes hold the most compelling bone density clinical trial evidence of any food in this series. Passion fruit’s fiber density stands alone.

The letter P makes the strongest collective case yet that common fruits and uncommon fruits are equally worthy of regular consumption, just for entirely different reasons.

All nutritional values are approximate and based on USDA FoodData Central data and available scientific literature. Values for exotic or tropical fruits may vary by variety, ripeness, and growing conditions.
