黄瓜促进骨骼健康

The nutrient in cucumbers is vitamin K, which is key for bone health. One cup of cucumber with the peel still on supplies over 20% of the recommended daily target for vitamin K. This nutrient is required for bone formation, and several studies have linked low K levels to osteoporosis and increased fracture risk.
黄瓜含有维生素K，该维生素对于骨骼健康至关重要。一杯带皮的黄瓜能提供日推荐摄入维生素K含量的20%。这一营养物质是骨骼形成所必需的，一些研究认为维生素K水平低与骨质疏松症和骨折风险增加有关。

黄瓜或能促进心血管健康

Cucumbers contain dozens of antioxidants, including flavonoids, which are known to protect against heart disease. The seeds may also be beneficial: In a study published last year, a small group of people with mildly elevated blood fats consumed dried cucumber seed extracts daily. After six weeks they experienced a number of favorable changes, including decreased total cholesterol, decreased "bad" LDL cholesterol, increased "good" HDL, and decreased triglycerides.
黄瓜含有多种抗氧化剂，包括能预防心脏病的类黄酮。黄瓜籽也能带来健康益处：去年发表的一篇文章中，一小组血脂水平略高的人每天都食用干的黄瓜籽提取物。六周后，他们的情况出现了好转，包括总胆固醇水平降低、"有害"低密度脂蛋白胆固醇降低、"有益"高密度脂蛋白水平升高，以及甘油三酯水平降低。

Cucumbers may help reduce cancer risk
黄瓜或能降低患癌风险

Along with flax and sesame seeds, kale, broccoli, cabbage, strawberries, apricots, and other plant foods, cucumbers contain a natural substance called lignans. Bacteria in the digestive tract convert lignans into compounds that bind onto estrogen receptors. Some preliminary studies suggest they may protect against estrogen-related cancers, including those of the breast, ovary, uterus, and prostate.
除了亚麻和芝麻籽、羽衣甘蓝、西兰花、卷心菜、草莓、杏子和其它植物性食物之外，黄瓜也含有一种叫作木脂素的天然物质。消化道中的细菌会将木脂素转化为与雌激素受体相结合的化合物。一些初步研究表明，它们或能预防与雌激素相关的癌症，包括乳腺癌、卵巢癌、子宫癌和前列腺癌。

Cucumbers can soothe skin
黄瓜可舒缓肌肤

Popping a few cuke slices on puffy eyes actually makes a lot of sense.
