A paper recently issued in Japan indicates that watermelons are also rich in lycopene and carotene: the content of these nutrients in red-fleshed watermelons is three times that of tomatoes, and that the content in seedless watermelons is double that of red-fleshed watermelons; moreover, the nutrients can be absorbed into the body when eaten raw.
日本最近發表的一項報告則指出，西瓜也含有豐富的茄紅素和胡蘿蔔素；紅色果肉的西瓜，營養素含量是蕃茄的 3 倍，無籽西瓜的含量更超出紅肉西瓜一倍，而且剖開生食就可以吸收。
