Both cantaloupe and watermelon offer hydrating, low-calorie nutrition with distinct vitamin and mineral profiles that support overall health.
Nutritional Profiles of Cantaloupe and Watermelon
Cantaloupe and watermelon are two of the most popular summer fruits, loved for their juicy sweetness and refreshing qualities. While both fruits share similarities in hydration and calorie content, their nutritional breakdowns reveal unique strengths that can influence your dietary choices.
Cantaloupe, a type of muskmelon, is packed with vitamins A and C, making it an excellent choice for immune support and skin health. Watermelon, on the other hand, shines with its high water content—about 92%—and contains notable amounts of lycopene, a powerful antioxidant linked to heart health.
Both fruits are naturally low in calories, making them ideal for snacking or adding volume to meals without overloading on energy. However, their carbohydrate and sugar contents differ slightly, which might be relevant depending on your nutritional goals.
Caloric and Macronutrient Comparison
Per 100 grams serving, cantaloupe provides around 34 calories while watermelon offers slightly fewer at 30 calories. This small difference makes both fruits equally suitable for calorie-conscious diets.
Carbohydrates dominate the macronutrient profile in both fruits since they are primarily composed of natural sugars such as fructose. Cantaloupe contains approximately 8 grams of carbohydrates per 100 grams serving, whereas watermelon has about 7.6 grams.
Protein content is minimal in both but present nonetheless—cantaloupe offers roughly 0.8 grams per 100 grams compared to watermelon’s 0.6 grams. Fat is negligible in both fruits.
Vitamin Content: Spotlight on Vitamins A and C
Vitamins A and C are vital antioxidants found abundantly in cantaloupe but present in lower quantities in watermelon.
Cantaloupe boasts a high vitamin A content due to its rich beta-carotene levels—the pigment responsible for its orange flesh. One hundred grams of cantaloupe supplies approximately 3382 IU (international units) of vitamin A, covering about 68% of the recommended daily intake (RDI). Vitamin A plays a critical role in vision health, immune function, and cell growth.
Watermelon contains much less vitamin A—around 569 IU per 100 grams—but compensates with a generous dose of vitamin C. Both fruits provide vitamin C to help combat oxidative stress and boost immunity; cantaloupe offers about 36.7 mg per serving (61% RDI), while watermelon provides roughly 8.1 mg (14% RDI).
Lycopene: The Red Powerhouse in Watermelon
Watermelon’s vibrant red flesh owes its color to lycopene—a carotenoid antioxidant linked to reduced risk of certain cancers and cardiovascular diseases. Lycopene concentration in watermelon far exceeds that found in cantaloupe or many other fruits.
Studies suggest lycopene helps neutralize free radicals that damage cells, improving heart health by lowering LDL cholesterol oxidation and blood pressure levels. For those seeking antioxidant-rich foods beyond vitamins A and C, watermelon shines as a top contender.
Minerals: Potassium, Magnesium, and Beyond
Minerals play crucial roles in maintaining fluid balance, nerve function, muscle contraction, and bone health.
Cantaloupe contains approximately 267 mg of potassium per 100-gram serving—important for regulating blood pressure—and provides modest amounts of magnesium (21 mg), calcium (9 mg), and iron (0.21 mg).
Watermelon also offers potassium but at slightly lower levels around 112 mg per serving. Magnesium is present at about 10 mg per serving with trace amounts of calcium (7 mg) and iron (0.24 mg).
Potassium’s role is especially critical given the high water content of these fruits; it helps replenish electrolytes lost through sweating during hot weather or exercise.
Hydration Benefits
Both cantaloupe and watermelon are over 90% water by weight—cantaloupe clocks in at roughly 90%, while watermelon exceeds this at about 92%. This makes them exceptional choices for hydration during warm months or after physical activity.
Consuming these fruits helps maintain electrolyte balance due to their potassium content while delivering fluids that support kidney function and skin hydration.
Sugar Content: Natural Sweetness Explained
The natural sugars present in cantaloupe versus watermelon contribute to their sweet taste but vary slightly in quantity.
Cantaloupe contains about 7.9 grams of sugar per 100 grams compared to watermelon’s approximately 6 grams per serving. The main sugars include fructose, glucose, and sucrose—all naturally occurring carbohydrates metabolized by the body for energy.
For individuals managing blood sugar levels or diabetes concerns, both fruits have relatively low glycemic indices but should still be consumed mindfully as part of balanced meals.
Fiber Content Differences
Dietary fiber supports digestion by promoting regular bowel movements and feeding beneficial gut bacteria.
Cantaloupe provides around 0.9 grams of fiber per 100-gram serving; watermelon has slightly less at approximately 0.4 grams. Though not significant sources compared to other fiber-rich foods like whole grains or legumes, these fruits contribute modestly toward daily fiber intake while delivering hydration benefits.

Culinary Uses Impacting Nutritional Benefits
How you enjoy cantaloupe or watermelon can influence how much nutrition you absorb from each fruit.
Fresh slices eaten raw deliver the full spectrum of vitamins without added calories or fats that might interfere with absorption or digestion processes.
Blending these fruits into smoothies retains most nutrients but may increase glycemic load due to easier digestion compared to chewing whole fruit.
Cooking or grilling melon is uncommon but possible; however heat can degrade sensitive vitamins like vitamin C reducing overall antioxidant capacity.
Pairing these fruits with healthy fats such as nuts or yogurt can enhance absorption of fat-soluble vitamins like vitamin A found abundantly in cantaloupe’s orange flesh.
Pitfalls to Watch For: Allergies & Sensitivities
Though rare, some individuals may experience allergic reactions to melons including cantaloupe or watermelon due to cross-reactivity with pollen allergens like ragweed or grass pollen.
Symptoms can range from mild itching around the mouth to more severe responses requiring medical attention.
If you notice unusual oral irritation after eating either fruit consistently, consulting an allergist is advisable before continuing consumption regularly.
Sustainability & Seasonal Availability Affecting Nutrition Quality
The freshness factor plays a big role in nutrient quality for both cantaloupe and watermelon.
Locally sourced melons consumed soon after harvest tend to retain higher vitamin levels than those stored long periods or transported over great distances under suboptimal conditions.
Seasonality also dictates availability; peak melon season usually spans summer months when nutrient density peaks due to optimal growing conditions including sunlight exposure which boosts carotenoid synthesis especially important for vitamin A content in cantaloupes.
Choosing organic options may reduce pesticide exposure though nutrient differences between organic vs conventional melons remain minimal based on current research data.
