On hot summer days, some foods can help you stay hydrated. When the temperature rises make a splash in your daily diet with these ideas:

Super salads. Watermelon, oranges, tomatoes, peppers, cantaloupe, berries, celery and cucumbers are all flush with fluid. These water-rich foods make great low-calorie snacks too!

Berry-delicious smoothies. Add berries — fresh or frozen — to low-fat or fat-free yogurt or milk. Puree in a blender.

Summer salsas. These can be made from vegetables, fruits or a combination of both. Enjoy your favorite variety as a snack — dip into it with cut-up veggies or whole-grain pita chips. Or top grilled fish or chicken with it. Have a sweet tooth? Give orange or pineapple salsa a try.

Chilled soups. You can serve these as a light meal — or as an appetizer or dessert. Here are three cool and soothing options:

• Gazpacho. A summertime favorite that's typically rich in tomato, cucumber, onion, bell pepper and garlic.
• Vichyssoise. This creamy French classic is made with pureed potatoes and leeks. To keep it on the healthful side, use low-fat, low-sodium chicken broth. For an even creamier soup, stir in a little plain low-fat yogurt or low-fat sour cream.
• Fruit soups. Strawberries, raspberries and cantaloupe puree nicely. See "Chilled melon soup" for a recipe to try.

Frozen nibbles. Freeze grapes or berries. Grab them for a quick and cold snack.
