Onion
You might relegate onions to the list of old-fashioned kitchen standbys, as you can slice and dice them into everything from home fries and soups to omelets and casseroles.
But onions can lend your dishes a powerful nutritional punch in addition to their trademark flavor. These pungent bulbs are rich in fiber, minerals, and vitamins C and B6. Scientists are interested in onions' abundant polyphenol and sulfur-containing compounds, such as quercetin and allyl sulfides, that may lower the risk of some cancers and help maintain heart health and immune function.
洋葱
你大概会把洋葱归为老式餐点佐料，因为什么菜都可以加点洋葱切片，你可以炸洋葱圈，炖洋葱汤，煎洋葱烩蛋，还能把它扔到砂锅里去煮一煮。
但洋葱不仅能在菜品里加入它自身独特的味道，还能提高营养价值。这些气味呛鼻刺眼的东西富含纤维素、矿物质、维生素C和维生素B6。科学家感兴趣于洋葱所富含的多酚以及含硫化合物，比如槲皮素和硫化丙烯，它们或许能降低某些癌症的患病风险，维护心脏健康和免疫功能。
