My favorite new food discovery is nutritional yeast. If you don't know about it yet, let me introduce you. I use it as a Parmesan cheese substitute. I put it on salads and soups, but you can also top your casseroles, pasta, and popcorn with it.

It is inactive so it does not have leavening ability. I buy it from the bulk bin at Whole Foods. Nutritional yeast is a good source of B vitamins, folic acid, selenium, zinc, and protein. Some describe it as having a cheesy, nutty flavor. I have been eliminating dairy from my diet, so I like having nutritional yeast as my "cheese."

When I posted this on the FQL Facebook page, one follower said, "After watching my daughter, who is allergic to dairy, look longingly at plates of mac and cheese, I found that I could use nutritional yeast to make the sauce. It looks the same as the stuff her friends have and she loves the taste! I felt like a star!"

I also recently posted about healthy alternatives for soda. I have given up Diet Coke for health reasons, but I miss the taste of it. I received some great ideas from everyone and decided to share them in an Examiner article I wrote today, "4 healthy alternatives to help kick the soda habit."

Another favorite healthy food swap of mine is cauliflower "mashed potatoes." Steam cauliflower and put it in a food processor. You can add a little butter (and nutritional yeast!). Blend and serve. It tastes just like mashed potatoes. Potatoes are fine nutritionally but cauliflower is even better.
