Watercress
豆瓣菜
Why we love it: "Watercress contains many phytochemicals, such as glucosinolates, which are plant compounds that offer disease prevention," Livestrong reports. It adds that the peppery, somewhat bitter green "has a higher antioxidant concentration than apples or broccoli."
豆瓣菜包含很多植物化学物质，如硫代葡萄糖苷，这是一种可以抗病的植物化合物。豆瓣菜内所含的抗氧化物比苹果或西兰花高。
