Recent studies show that your diet can improve your appearance, and what you eat affects the way you look. Good fats found in walnuts and seafood fight wrinkles. Foods packed with Vitamin A, like butternut squash, carrots & cantaloupe, help block UV radiation. Vitamins C & E, found in broccoli & citrus fruits encourage collagen formation (which keeps you younger looking). To avoid breakouts, steer clear of refined carbs. If you give your diet a makeover, your face may get one, too!
