While most people wouldn’t think twice about adding a reduced  or non-fat dressing to their salad, doing so actually prevents you from gaining leafy greens’ full nutritional benefits. Foods high in carotenoids -- such as spinach, tomatoes, and carrots -- actually require some amount of fat in order for the nutrients to be absorbed by the body. In fact, when you lose the fat, you often lose the flavor. How do major manufacturers remedy this? Add sugar. So put down that Kraft (KFT) fat-free dressing -- it isn’t doing you any favors. Instead, try making your own dressing with olive oil, balsamic vinegar, and fresh squeezed lemon or orange juice. It’s not only better for you -- it tastes better, too.
