Yellow Watermelon: Nutrition, 20 Benefits & Side Effects

Yellow watermelon is a colorful variety of watermelon with bright yellow flesh instead of the familiar red or pink flesh. It belongs to the same species, Citrullus lanatus, and has a juicy, refreshing texture similar to traditional watermelon. Depending on the variety, its flavor can range from mildly sweet to noticeably honey-like.

The yellow color comes from a different combination of carotenoid pigments. Unlike red watermelon, which is particularly rich in lycopene, yellow-fleshed varieties contain different carotenoids, including beta-carotene, alpha-carotene, lutein, and other xanthophylls. Research suggests that yellow watermelon generally has similar amounts of water, calories, carbohydrates, sugars, protein, fat, and fiber to red watermelon, although its carotenoid and vitamin composition can differ. Yellow watermelon can be a refreshing addition to a balanced diet, particularly when eaten as fresh fruit rather than as a sugary juice or dessert.

What Is Yellow Watermelon?

Yellow watermelon is a naturally occurring and cultivated variety of watermelon that has yellow-colored flesh. Its botanical name is Citrullus lanatus, the same species as many red-fleshed watermelons.

Its unusual color is mainly related to its carotenoid profile. Studies of yellow-fleshed varieties have identified compounds such as beta-carotene, alpha-carotene, lutein, xanthophylls, and small or trace amounts of lycopene. The exact nutritional composition varies according to cultivar, growing conditions, ripeness, and storage.

Yellow watermelon is naturally high in water and relatively low in calories. It also provides carbohydrates, natural sugars, potassium, vitamin C, and the amino acid L-citrulline. Watermelon in general is one of the better dietary sources of L-citrulline.

Allergic Reaction: Although uncommon, watermelon can cause allergic symptoms in susceptible individuals.
Oral Allergy Symptoms: Some people with pollen-related allergies may experience itching or tingling in the mouth after eating certain raw fruits.
Excessive Fluid Intake: Eating very large quantities can add a substantial amount of fluid to the diet.
