西瓜有啥营养优势？ 夏天和西瓜真的很搭！炎热的天气下，汗流浃背、食欲不佳，吃一口冰凉多汁又爽口的西瓜，相当过瘾。 西瓜除了水分高，还有没有其他值得吃的营养？炎炎夏日又该如何健康吃西瓜呢？这份"吃瓜大全"，送给你→ 01 补水是夏季的重中之重，我们吃西瓜最大的感受就是"太补水了"。西瓜的水分含量高达90%以上，真是消暑解渴的好帮手。在其他营养上，西瓜还含有维 生素C、膳食纤维、钾、镁等营养，但含量都不是很高，在水果中算不上有优势，其中维生素C的含量只有5.7毫克/100克，值得一提的是西瓜中的番茄红 素。 另外，西瓜的热量很低，只有31千卡/100克，有的品种热量只有26千卡/100克，都不到苹果的一半。只要不狂炫，减肥的小伙伴就不用担心会长胖。 02 西瓜冷藏后吃，更甜 很多人会发现，如果把西瓜冰镇之后再吃，口感会更甜。这不是错觉，是有科学依据的。 这是因为西瓜的总糖含量为6.2克/100克，蔗糖、葡萄糖、果糖的含量分别为1.21克/100克、1.58克/100克、3.36克/100克，由此可见西瓜的果糖含量较高。 不过，有些品种的西瓜虽然果糖含量也不低，但蔗糖含量更高一些，比如京美2K、超甜梦想、光辉L10 ...
