3. Apples 苹果

Don't peel these babies! You probably heard that from your mother, and she was right on target. The skin of the apple contains quercetin, a powerful antioxidant that protects against skin cancer. Apples also are a good source of fiber¹, meaning you feel full for hours after eating one.

不要削皮！妈妈可能这样说过，她说的没错。苹果皮中含有槲皮素，槲皮素是一种强力抗氧化剂，能够预防皮肤癌。苹果中还富含纤维，进食一个苹果，几小时都不会饿。

4. Nuts 坚果

Nuts, especially walnuts², almonds and hazelnuts, are high in omega-3 fat. And your skin really benefits from the moisture that brings. Nuts are also high in arginine, an amino acid that helps you burn fat.

坚果类，特别是核桃、杏仁和榛子中富含ω- 3脂肪酸，ω- 3脂肪酸能使皮肤保持水润。坚果中的精氨酸含量也很高，这种氨基酸能帮助燃烧脂肪。
