Dry or Damaged Skin
What causes it: You sweat more in the summer, so skin is less supple; plus, saltwater and chlorine have a drying effect. Sunburns and bug bites are also saboteurs of healthy skin.
What to eat: Help heal weathered skin with foods like raspberries, blueberries, and strawberries, which are rich in antioxidants and vitamin C. Protein, in the form of lean meats, beans, nuts, and seeds, is also key. Keep dryness at bay by drinking lots of water, which Lona Sandon, RD, calls "the forgotten nutrient." Sandon is a spokeswoman for the American Dietetic Association. She recommends that women drink 92 ounces (8-10 cups) of water in the summer and men 125 ounces to prevent dehydration. Since calcium can also be lost through sweating, it's a good idea to replace it by eating low-fat dairy products like skim milk, yogurt, and cottage cheese.
