10. Dark Chocolate 黑巧克力
Chocolate! Bring it on. Dark chocolate is a good source of those age-fighting antioxidants, and it also contains the mood elevator phenylethylamine, according to the California Academy of Sciences. So no, it's not your imagination that you feel happy when you eat dark chocolate. Just don't overdo it; too much of a good thing might turn out to be a bad thing in this case.
巧克力！来一口。黑巧克力中的抗氧化剂能延缓衰老。据加利福尼亚科学院研究，巧克力中的苯乙胺能提升情绪抗抑郁。所以，吃巧克力的时候会感到开心，那可不是你的幻觉。只是记得不要一次吃太多，物极必反，过犹不及。
