3. Watermelon 西瓜

　　Until the age of 55, more men suffer from high blood pressure than do women. Research suggests that foods rich in potassium can reduce the risk of high blood pressure. Watermelon, a rich source of this mineral, has more potassium--664 mg --in one large slice than the amount found in a banana or a cup of orange juice. So cut yourself another slice and enjoy the taste of summer.

　　男人在55岁前受高血压折磨的比例要比女人高。研究表明，富含钾的食物可以降低罹患高血压的风险。西瓜富含钾元素，一大片西瓜中就含有664毫克钾，这比香蕉或者一杯橙汁中钾的含量要高得多。所以再来一块西瓜吧，尽情享受夏天的滋味。
