吃货过夏天：9种最健康的夏日食物

夏天天气热我们可能都不想吃东西，但夏天也是需要注意身体健康和营养摄入的关键时期。下面这9种最健康的夏日食物，有一些是时令食物，有一些也许有很多你以前忽略了的营养价值。

Watermelon
西瓜

This beloved thirst quencher is packed with vitamins A, C, potassium, and the cancer-fighting antioxidant lycopene, according to WebMD. It’s also one of the richest natural sources of the amino acid L-citrulline, which helps regulate arterial function and may lower blood pressure, as discovered by researchers in a 2010 Florida State University study.
WebMD网站上说，这可是富含维生素A，C, 钾以及抗癌抗氧化剂的番茄红素的解渴利器。佛罗里达大学2010年的研究发现，西瓜同时还富含最丰富的氨基胱氨酸，能有效防止动脉硬化还能降低血压。

Shrimp
虾

Yes, shrimp contain cholesterol. But many researchers think that the cholesterol you consume from food plays a negligible effect on cholesterol in your bloodstream. Shrimp is also high in protein, low in fat and a good source of heart-protective omega-3s and vitamin B12, according to Outside magazine.
没错，虾富含胆固醇。但很多研究人员认为从食物中摄取的胆固醇对血管里胆固醇的影响微乎其微。根据Outside杂志，虾还富含蛋白质、低脂肪，还富含保护心脏的omega-3s以及维他命B12。

Iceberg lettuce
卷心莴苣

Darker greens may have more nutrients, says Prevention magazine, but that doesn’t mean iceberg has none. If an iceberg wedge is your favorite salad, note that one cup of shredded leaves delivers about 20 percent of your daily needs for vitamin K, and 15 percent for vitamin A. Even if you use iceberg as a salad base for other healthy veggies, you've got a great vehicle for overall nutrition.
Prevention杂志说深绿色植物富含的营养成分也许更多， 但这也不意味着卷心莴苣就没有营养。如果卷心菜叶是你最喜欢的沙拉，那就记住一杯菜叶能给你提供每日所需20%的维他命K和15%的维他命A。即使菜叶只是用来作为其他健康蔬菜的色拉搭配，你也可以从中获得充分的营养。
