Ever heard that the white stuff we eat is not so healthy? I've heard it, time and time again. I was reminded of this fact while at Canyon Ranch in Tucson, Arizona this past April. My Ranch nutritionist confirmed it. And the foods I ate while at this health and healing institute derived from the whole wheat, whole grain, whole goodness family. There wasn't a slice of white bread in sight. No white pasta either. Or white rice. I did have a white baked potato one night for dinner -- but it was the smallest white baked potato I'd ever seen.

It's not so hard to transition from white to non-white. Just search your grocery store aisles for the healthier alternatives -- and buy them. Or make your own varieties of nutritious stuff. Like whole-wheat pizza crust. Remember when I wrote about eating pizza once a week? Instead of ordering it, why not make your own? Here's how you might start:

Whole-Wheat Pizza Crust
Makes six pizza crusts, each containing 175 calories, 36 gm. carbohydrate, 1 gm. fat, 0 mg. cholesterol, 6 gm. protein, 150 mg. sodium, and 4 gm. fiber

Pizza just might have the power to fight cancer -- not the pizza loaded with cheese and pepperoni and tons of tempting toppings, the kind that may have your mouth watering at this very moment. But a version of pizza as we know it may fend off heart disease, obesity, and cancer.

The secret is in the crust -- the cooking of the crust, that is.

Think about this:

It seems baking pizza faster and at higher temperatures can release disease-fighting antioxidants. And it's this one small change to pizza preparation that has scientists at the University of Maryland claiming there is such a thing as a healthy pizza.

Scientists baked pizza at 500 degrees for six minutes and were able to increase antioxidant levels 100 percent. They used whole wheat dough, already high in antioxidants, and let it rise overnight before using their hotter, quicker cooking approach.

One researcher says this study is more a lab curiosity than anything else and might not really lead to a healthier pizza -- because it's unlikely pizza joints will change cooking methods to turn out healthier products.

If you are tempted to try this technique, be aware that the toxin acrylamide can be released if the pizza is baked too long. And don't forget to cut way back on those tasty toppers.
