Yum!

Richer in heart-healthy omega-3s than salmon, loaded with more anti-inflammatory polyphenols than red wine, and packing half as much muscle-building protein as chicken, the walnut sounds like a Frankenfood, but it grows on trees. Other nuts combine only one or two of these features, not all three. A serving of walnuts—about 1 ounce, or seven nuts—is good anytime, but especially as a postworkout recovery snack. SUBSTITUTES: Almonds, peanuts, pistachios, macadamia nuts, hazelnuts FIT IT IN: Sprinkle on top of salads; dice and add to pancake batter; spoon peanut butter into curries; grind and mix with olive oil to make a marinade for grilled fish or chicken. HOME RUN: Mix 1 cup walnuts with ½ cup dried blueberries and ¼ cup dark chocolate chunks.
