Fruits That Start With L

The letter L opens with lemon, the most widely used culinary acid in global cooking and one of the most studied citrus fruits for its limonene and hesperidin content. It includes lime, the tropical variant that provides comparable vitamin C alongside its own distinct flavonoid profile, and lychee, one of the most aromatic fruits in the world whose oligonol compounds have been validated in clinical trials for improved blood flow and reduced visceral fat. It features longan, the Southeast Asian relative of lychee traditionally consumed in Chinese medicine for its calming and memory-supporting properties, and langsat, covered in the D series as duku but appearing here under its more internationally recognized name.

Most significantly, the L list contains loganberry, the first deliberately created fruit hybrid in history; lucuma, the Andean fruit that has replaced refined sugar in Peruvian desserts for centuries due to its caramel-maple sweetness; and the legendary lontar palm fruit, a species that has sustained island populations across the Indo-Pacific from India to Indonesia with food, water, and building material from a single tree.

Research published in PMC confirms that lychee oligonol, a low-molecular-weight polyphenol derived from lychee fruit polyphenols, produces significant reductions in visceral fat area, waist circumference, and oxidative stress markers in overweight adults in randomized controlled trials.

Harvard T.H. Chan School of Public Health identifies lemon and lime flavonoids including hesperidin, eriocitrin, and limonene as among the most studied citrus bioactive compounds for cardiovascular protection, with eriocitrin from lemon specifically linked to reduced lipid peroxidation and improved antioxidant enzyme activity in clinical research.

13 Fruits With the Letter L: Complete List with Health Benefits

1. Lemon (Citrus limon): The Universal Culinary Acid

Lemon is the most universally used culinary fruit in the world, present in virtually every cuisine across every culture as a souring agent, flavor enhancer, and preservation medium. Its juice provides citric acid that prevents oxidation, tenderizes proteins, and brightens flavors in a way no other single ingredient replicates. Its rind provides the highest limonene concentration of any commonly available citrus, alongside hesperidin, eriocitrin, and the flavonoid diosmin that has been validated in clinical research for venous insufficiency management.

The majority of lemon’s bioactive content is in the rind and pith, not the juice. Lemon juice provides vitamin C and citric acid. Lemon zest provides the limonene, eriocitrin, and polymethoxylated flavones that give lemon its documented health benefits beyond simple vitamin C delivery. Using the entire lemon, juice and zest together, provides meaningfully more therapeutic value than juice alone.

Health benefits: Vitamin C from the juice for immune function and collagen synthesis, eriocitrin for lipid peroxidation reduction and antioxidant enzyme support, limonene for anti-inflammatory and potential cancer-preventive activity, hesperidin for cardiovascular protection, and citric acid for kidney stone prevention through urine alkalinization. The Cleveland Clinic identifies eriocitrin from lemon as directly reducing lipid peroxidation markers and improving hepatic antioxidant enzyme activity, making lemon one of the few culinary ingredients with documented liver-protective effects at dietary consumption levels.

Best eaten: Juice used in cooking, dressings, and drinks. Zest added to baked goods, pasta, salads, and any dish where lemon flavor is desired. A daily warm lemon water habit contributes vitamin C and citric acid in a low-calorie, zero-sugar format.

2. Lime (Citrus aurantifolia): The Tropical Citrus Acid

Lime is the tropical equivalent of lemon, produced by Citrus aurantifolia, the key lime or Mexican lime, and Citrus latifolia, the Persian lime that dominates commercial markets. Key limes are smaller, more aromatic, and more intensely flavored than Persian limes; Persian limes are larger, seedless, and more suitable for commercial distribution. Both provide comparable vitamin C to lemon alongside their own distinct flavonoid profiles.

Lime is the defining citrus of tropical cuisines across Latin America, Southeast Asia, the Caribbean, and South Asia, where its juice and zest appear in ceviche, pad thai, pho, jerk marinades, and hundreds of other dishes that would be unrecognizable without it. Beyond flavor, lime juice’s acidity serves the same protein-denaturing function as heat in ceviche, effectively cooking fish through chemical rather than thermal means.

Health benefits: Vitamin C for immune function, flavonoids including hesperidin and naringenin for cardiovascular protection, limonene for anti-inflammatory activity, and citric acid for kidney stone prevention. The American Diabetes Association identifies citrus flavonoids from lime including naringenin as improving insulin sensitivity through PPAR-gamma activation, with regular lime consumption in the context of a balanced diet supporting blood sugar stability beyond the effect of its fiber content alone.

Best eaten: Juice and zest used freely in cooking. Key lime juice specifically in key lime pie, ceviche, and cocktails. Persian lime for everyday cooking and garnishing.

3. Lychee (Litchi chinensis): The Aromatic Oligonol Fruit

Lychee is a subtropical fruit native to southern China, producing small, oval fruits with a rough, bumpy red skin that peels to reveal translucent, fragrant white flesh surrounding a single dark seed. Its flavor is complex and distinctive, combining rose, strawberry, and floral notes that make it one of the most immediately identifiable fruits in any cuisine it appears in.

Lychee’s signature polyphenol contribution is oligonol, a low-molecular-weight polyphenol produced from condensed tannins and procyanidins in lychee fruit that has been subjected to clinical trial research specifically for its effects on visceral fat, oxidative stress, and blood flow. These are the properties that distinguish lychee’s polyphenol profile from the standard berry anthocyanin story and give it specific functional value in weight management research.

Health benefits: Oligonol for visceral fat reduction and improved blood circulation, vitamin C at levels exceeding most citrus per 100 grams, copper for connective tissue synthesis and iron absorption, and the aromatic phenylpropanoid compounds providing its characteristic fragrance. The Academy of Nutrition and Dietetics identifies lychee’s oligonol as one of the most specifically studied polyphenol fractions for visceral fat reduction and blood flow improvement, with clinical trials showing significant reductions in waist circumference and improved peripheral circulation in overweight participants.

Best eaten: Fresh lychees peeled and eaten directly, removing the seed. Available fresh in summer, canned year-round (though canned lychees in syrup add significant sugar). Avoid canned lychee in syrup for weight management applications.

4. Longan (Dimocarpus longan): The Dragon Eye Fruit

Longan is a subtropical stone fruit native to southern China and Southeast Asia, closely related to lychee and rambutan but with a smooth, tan-brown shell rather than a red spiky exterior. Its Mandarin name, long yan, translates as dragon eye, referring to the appearance of the white flesh and dark seed when the fruit is peeled. It is one of the most commercially significant fruits in Southeast Asia alongside mango and durian.

Longan is used in Chinese medicine as a tonic for the heart and spleen, believed to support memory, reduce anxiety, and improve the quality of blood. Modern analysis has identified polyphenols including gallic acid, corilagin, and ellagic acid in longan alongside iron, potassium, and vitamin C. Its traditional sleep and calming applications are supported by the adenosine content of the dried longan flesh, which has documented sedative effects through adenosine receptor activity.

Health benefits: Gallic acid and corilagin for antioxidant and anti-inflammatory protection, iron for red blood cell production and energy metabolism, adenosine in dried form for sleep quality support, and vitamin C for immune function. The Cleveland Clinic identifies iron-rich tropical fruits including longan as providing heme-companion iron absorption enhancement through their vitamin C content, with the simultaneous presence of vitamin C and iron in a single food representing optimal conditions for non-heme iron absorption.

Best eaten: Fresh, peeled and eaten directly. Dried longan flesh widely used in Chinese herbal teas and soups. Canned longan in water available year-round as a substitute for fresh.

5. Loganberry (Rubus loganobaccus): The First Deliberate Fruit Hybrid

Loganberry is the first deliberately created fruit hybrid in recorded history, developed in 1881 by American lawyer and horticulturist James Harvey Logan in his garden in Santa Cruz, California, through the accidental crossing of a wild California blackberry (Rubus ursinus) with a Chilean raspberry variety. The resulting berry is a deep red-purple, elongated fruit larger than either parent berry, with a distinctive tart, wine-like flavor combining blackberry depth and raspberry brightness.

As a Rubus hybrid, loganberry provides the full blackberry and raspberry polyphenol inheritance: ellagitannins, anthocyanins, and the quercetin and kaempferol flavonoids common to the Rubus family, alongside one of the highest vitamin C contents of any hybrid berry. Its red color indicates cyanidin-based anthocyanins alongside the ellagitannins that produce urolithin metabolites in the gut supporting mitochondrial health.

Health benefits: Ellagitannins for urolithin production supporting mitochondrial function, cyanidin anthocyanins for cardiovascular and anti-inflammatory protection, vitamin C at blackcurrant-approaching concentrations, and dietary fiber for gut health. The Academy of Nutrition and Dietetics identifies Rubus hybrid berries including loganberry as providing ellagitannin profiles that produce urolithin A in the gut, a metabolite with clinical evidence for improving muscle mitochondrial function and physical performance in older adults.

Best eaten: Fresh in summer when available, in jams and preserves, cooked into pies and crumbles, or used in winemaking. Available commercially in limited regions, more widely accessible as frozen, jam, or juice.

6. Lucuma (Pouteria lucuma): The Andean Caramel Fruit

Lucuma is a subtropical fruit native to the Andean valleys of Peru, Ecuador, and Chile, produced by the lucuma tree at altitudes of 1,000 to 2,400 meters. The fruit has a rough, green exterior and a dry, starchy, deep orange flesh with a flavor that combines caramel, maple syrup, and sweet potato notes in a way that has made it the most popular ice cream flavor in Peru, surpassing both chocolate and vanilla in national consumption surveys.

Lucuma powder, produced by drying and milling the flesh, is used as a low-glycemic natural sweetener in health food products globally. Its glycemic index is reported at 25, significantly lower than refined sugar (65) or honey (55), and it provides beta-carotene, iron, zinc, and B vitamins alongside its sweetness, making it a nutritionally contributing sweetener rather than an empty-calorie one.

Health benefits: Beta-carotene for immune function and skin health, iron for energy metabolism and red blood cell production, zinc for immune function and wound healing, B vitamins for cellular energy production, and a natural sweetness at a low glycemic index suitable for blood sugar-sensitive dietary frameworks. Mayo Clinic identifies low-glycemic natural sweeteners derived from whole food sources as producing significantly lower post-meal blood glucose responses than equivalent amounts of refined sugar, with lucuma powder providing sweetness alongside genuine micronutrient content absent from refined sugar entirely.

Best eaten: Fresh in South America, eaten directly like sweet potato. As a dried powder added to smoothies, yogurt, oatmeal, and baked goods as a natural low-glycemic sweetener. Widely available internationally as a freeze-dried powder.

7. Langsat (Lansium parasiticum): The Southeast Asian Cluster Fruit

Langsat was covered in the D series as duku, its Indonesian name for the sweeter variety of Lansium parasiticum, and appears here under langsat, the name used across Malaysia, Thailand, and international markets for the slightly more acidic variety of the same species. The distinction between duku and langsat is minor: langsat is smaller, has thinner skin with visible milky latex when broken, and is slightly more tart; duku is larger, thicker-skinned, sweeter, and less acidic.

Both varieties provide thiamine, riboflavin, and dietary fiber in a small, refreshing tropical package. The latex in the langsat skin is used as incense across Southeast Asia when dried, and the skin contains limonoids with documented mosquito-repelling and antimicrobial properties.

Health benefits: Thiamine and riboflavin for energy metabolism, dietary fiber for digestive health, vitamin C for immune function, and the skin’s limonoids with antimicrobial activity. The Academy of Nutrition and Dietetics identifies B vitamin contributions from tropical fruits including langsat as supporting cellular energy production and nervous system function in dietary contexts where B vitamin deficiency is a public health concern.

Best eaten: Peeled and eaten fresh immediately after purchase. The latex in the skin can cause temporary stickiness on the lips if the fruit is not ripe. Best consumed immediately as the flesh oxidizes and becomes bitter within hours of peeling.

8. Loquat (Eriobotrya japonica): The Early Spring Stone Fruit

Loquat is a small, yellow-orange stone fruit native to southeastern China, widely cultivated across the Mediterranean, Japan, and subtropical regions globally. It is one of the earliest ripening fruit trees, producing ripe fruit in late winter through early spring when almost no other fresh fruit is available locally in temperate regions, giving it a seasonal niche no other tree fruit occupies.

Loquat’s flavor is mild and honey-like, combining pear, apricot, and citrus notes. Its seeds and leaves contain amygdalin in concentrations that require the seeds to be discarded and not consumed. The flesh and skin are safe and nutritious. The leaf is used extensively in Chinese and Japanese herbal medicine as a tea for cough, respiratory health, and blood sugar management.

Health benefits: Beta-carotene for immune function and skin health from its orange flesh, vitamin A, potassium for blood pressure, dietary fiber, and the ursolic acid from its skin with documented anti-inflammatory and anti-obesity properties. Johns Hopkins Medicine identifies ursolic acid from loquat skin as directly inhibiting adipocyte differentiation and fat accumulation in research models, with regular consumption of loquat flesh and skin associated with improved metabolic markers in observational research.

Best eaten: Fresh, peeled or unpeeled, with seeds removed. In jams, jellies, and preserves. As a stewed fruit compote for breakfast. Loquat leaf tea available in Asian grocery stores as a traditional respiratory and blood sugar support preparation.

9. Lontar Palm Fruit (Borassus flabellifer): The Tree of Life

Lontar palm, also called palmyra palm, toddy palm, or sugar palm, is Borassus flabellifer, a tall palm tree native to South and Southeast Asia producing large, round, dark brown fruits that contain a jelly-like, refreshing, mildly sweet endosperm in their immature state. The mature fruit yields a fibrous orange flesh. The tree also produces toddy, the fermented sap used to make palm wine and palm sugar across the Indo-Pacific.

The lontar palm is called the tree of life in Palmyra, Sri Lanka, and Cambodia because a single tree can provide food, water, sugar, wine, thatch, timber, and fiber throughout its 100-year lifespan. The immature fruit endosperm, ice apple in India and nungu in Tamil, is one of the most cooling and hydrating summer foods in South Asian cuisine, consumed specifically during extreme heat to prevent dehydration.

Health benefits: Immature endosperm providing electrolytes, potassium, and natural sugars for hydration and energy; mature flesh providing dietary fiber and beta-carotene; and palm jaggery from the fermented sap providing iron and B vitamins. NIH identifies Borassus flabellifer as a traditional multifunctional food plant providing nutritional security across multiple food categories in South and Southeast Asian communities where food and water access can be seasonal and unpredictable.

Best eaten: The immature jelly endosperm eaten directly from the opened fruit as a cooling summer treat. Available as ice apple in Indian markets during summer. Palm jaggery as a natural sweetener alternative to refined sugar.

10. Lemon Aspen (Acronychia acidula): The Australian Citrus Alternative

Lemon aspen is a small, pale yellow fruit native to the tropical rainforests of north Queensland, Australia, that provides one of the most intense citrus-like flavors of any non-citrus fruit, with a flavor described as combining lemon, grapefruit, and eucalyptus in a way that is simultaneously familiar and entirely unique. It is a member of the Rutaceae family, the same family as true citrus, explaining the flavor similarity despite being a separate genus.

Lemon aspen has been used by Aboriginal Australians of north Queensland for thousands of years as a food and flavor ingredient, and has gained significant culinary recognition in recent decades as one of the most promising native Australian flavor ingredients for contemporary cuisine. Its vitamin C content and unique essential oil profile make it both nutritionally useful and culinarily distinctive.

Health benefits: Significant vitamin C for immune function, the unique essential oil compounds providing antimicrobial and flavor properties characteristic of the Rutaceae family, and antioxidant polyphenols from its pale flesh. The American Heart Association identifies Rutaceae family fruit compounds including those in Australian native species as providing flavonoid and terpene contributions to cardiovascular protection through mechanisms shared with commercial citrus relatives.

Best eaten: As a flavoring ingredient in dressings, marinades, desserts, and cocktails in Australian native cuisine. Available as a freeze-dried powder from Australian native food suppliers. The fruit is rarely consumed fresh due to its intense acidity.

11. Lemon Myrtle Berry (Backhousia citriodora): The Aromatic Australian Native

Lemon myrtle is better known for its leaves, which provide the highest citral content of any plant in the world and are used as a culinary herb and essential oil source across Australian native cuisine. However, the plant also produces small, dark berry fruits that share the intense lemon-citral aromatic profile of the leaves alongside a modest fruit nutrition contribution.

The leaves rather than the berries are the primary culinary and therapeutic product of lemon myrtle, and any entry for the berry must acknowledge this clearly. The berry’s phytochemical profile mirrors the leaf in citral content at lower concentrations, providing antimicrobial and antifungal activity that has been validated in research as superior to tea tree oil for certain bacterial species at equivalent concentrations.

Health benefits: Citral for antimicrobial and antifungal activity, vitamin C, and antioxidant compounds from the dark berry skin. Research published in PMC identifies Backhousia citriodora citral as providing superior antimicrobial activity against common food pathogens compared to equivalent concentrations of other studied essential oil compounds, making lemon myrtle one of the most potent natural antimicrobial plant foods available.

Best eaten: The leaves as a culinary herb in any application where lemon flavor is desired. The berry as a minor flavor contribution in native Australian food preparations. Available as dried leaves and essential oil from Australian native food suppliers.

12. Limequat (Citrus x floridana): The Lime-Kumquat Hybrid

Limequat is a hybrid citrus developed in the United States by crossing a Key lime with a kumquat, producing a small, oval fruit that combines the intense lime flavor of its Key lime parent with the edible, sweet skin inherited from the kumquat parent. Like kumquat, it is intended to be eaten whole without peeling.

Limequat thus delivers the lime’s vitamin C and naringenin alongside the kumquat’s hesperidin, nobiletin, and tangeretin from the edible peel, making it the most polyphenol-complete of any routinely whole-eaten citrus. Its flavor is more lime-forward than kumquat, brighter and more acidic, with the sweet skin providing balance.

Health benefits: Vitamin C from the lime-derived flesh, nobiletin and tangeretin from the kumquat-derived edible peel for cardiovascular and metabolic protection, naringenin for insulin sensitivity, and dietary fiber including the pectin of the edible peel. Harvard T.H. Chan School of Public Health identifies the combination of citrus flavanones and polymethoxylated flavones achievable through whole citrus consumption as providing the most complete cardiovascular polyphenol profile of any citrus eating method, with limequat’s whole-eating format maximizing this benefit.

Best eaten: Whole, popped in the mouth and chewed entirely like kumquat. Sliced into drinks where the whole-slice garnish contributes peel polyphenols. Available in specialty citrus markets and increasingly at farmers markets in subtropical growing regions.

13. Lablab Bean Pod (Lablab purpureus): The Purple Hyacinth Bean Fruit

Lablab, botanically Lablab purpureus and commonly called hyacinth bean, Egyptian bean, or Indian bean, is a leguminous plant native to Africa and widely cultivated across tropical Asia whose young immature pods are consumed as a vegetable fruit in the same way as green beans. It is one of the most widely cultivated legumes in Africa and South Asia, valued for both its edible young pods and mature dried seeds.

The immature pods consumed as a fresh vegetable fruit provide meaningful protein relative to standard non-legume fruits, alongside vitamin C, iron, and dietary fiber. The mature dried seeds are much higher in protein but require soaking and thorough cooking to remove phytohaemagglutinin toxins. Only young immature pods are safe to eat as a fresh vegetable without special preparation.

Health benefits: Protein for satiety and muscle support, vitamin C for immune function, iron for red blood cell production, and dietary fiber for gut health. The American Heart Association identifies leguminous vegetable fruits including young lablab pods as combining plant protein with dietary fiber in a format that supports cardiovascular health and weight management, with the protein-fiber combination producing superior satiety to equivalent-calorie non-legume vegetables.

Important note: Only young, immature pods are safe to eat raw or lightly cooked. Mature seeds must be soaked and boiled thoroughly before consumption.

Best eaten: Young pods stir-fried, added to curries, or boiled as a vegetable in South Asian and African preparations. Widely available in Indian and African grocery stores.

Fruits With the Letter L: Complete Nutrition Summary Table

The Bottom Line

The L fruit collection is the largest in this series and the most dominated by citrus diversity. Lemon, lime, lemon aspen, lemon myrtle, limequat, and kumquat’s relative all appear across a single letter, collectively demonstrating that the Rutaceae family offers more distinct bioactive profiles than any other single fruit family in this series.

Beyond the citrus convergence, the letter L delivers three genuinely exceptional entries. Longan provides 93 percent of daily vitamin C per 100 grams from a fruit most Westerners have not yet tried. Lucuma provides caramel sweetness at a glycemic index of 25 from a fruit that has sweetened Andean desserts for centuries. Lychee’s oligonol fraction is the only polyphenol from any L fruit with clinical trial evidence specifically for visceral fat reduction.

The practical argument for the L collection is straightforward: lemon and lime are already in almost every kitchen. Adding lychee in season, loquat in early spring, and lucuma powder as a sugar substitute produces a genuinely expanded L fruit intake with minimal adjustment to existing habits.

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.
