The outer layers of an onion pack the greatest antioxidant punch.
洋蔥的維生素和礦物質含量可能並不高。一箇中等大小的洋蔥含有大約44卡，提供20%的日需維生素C含量，以及5%至10%的維生素B6、葉酸、鉀元素和錳元素。但洋蔥富含十多種不同類型的抗氧化劑，包括槲皮素，一種強效消炎化合物。洋蔥的外皮含有最有效的抗氧化劑。They may protect against cancer
洋蔥可預防癌症In a study published in the American Journal of Clinical Nutrition, researchers looked at how often people in Italy and Switzerland ate onions and another Allium vegetable, garlic. They found that among the populations studied, there was an inverse link between the frequency of use of these veggies and the risk of several common cancers-meaning the more onions and garlic people ate, the lower the cancer rate.
《美國臨牀營養學雜誌》刊出的一項研究中，研究員研究了意大利和瑞士人吃洋蔥及另一種蔥屬植物大蒜的頻率。他們發現，在上述研究對象中，食用這些蔬菜的頻率與一些常見的癌症風險之間存在反向關聯--也就是，人們吃的洋蔥和大蒜越多，他們患癌的風險就越低。And improve bone density
增強骨骼密度One study that looked at perimenopausal and postmenopausal Caucasian women 50 and older found a link between onion consumption and bone health.

一項關於50歲以上高加索女性絕經期和絕經後的研究發現了洋蔥攝入和骨骼健康之間存在聯繫。吃洋蔥次數多的女性骨骼密度更強，與不吃洋蔥的女性相比，她們髖骨骨折的風險降低了20％以上。Onions also support healthy digestion
