Healthy food that tastes good, does it exist? (Score 1)

Is there such a thing as healthy food (say, less than 30% of the calories from fat) that tastes good?

I know lower fat substitutions in recipes can change the food chemistry. One of my favorite substitutions is evaporated whole milk (never tried using evaporated skim, I have a bad feeling about that) for cream in recipes. Am I really reducing the amout of fat?

What's your feeling on: reduced fat mayo, cheeses, salad dressing?

Do you have any other suggestions for lower fat substitutions?
