Give your fridge a healthy makeover

Looking in someone's fridge is like peeking in their medicine cabinet -- you can learn a lot about them from the foods they eat ... and also how punctual they are about throwing moldy leftovers out. WebMD thinks so too, and they've put together this short video in which one of their dietitians raids someone's fridge (I suspect her own because she loves pretty much everything in there.) Here are some must-have items according to her:

• Non-fat sour cream: This can be substituted for fat in a lot of recipes
  
• Light cream cheese: In baking recipes that call for lots of butter, you can use half butter, half light cream cheese for lots of richness without all the fat
• Soy milk: It's high in protein and calcium and taste, low in fat.
  
• Calcium-fortified orange juice: For those who don't drink milk
• Lots of fruits and veggies
• Omega-3 eggs: Not only do these eggs have lots of nutrients, they're lower in fat than regular eggs. That's because the chickens are fed healthier grains.
• Butter: Most dietitians are quite anti-butter but this one recommend having a bit in your house for baking purposes. While there are many ways to lower the amount of butter you use in a recipe, cutting it out altogether isn't always an option.
