Just as I'm starting to understand all the buzz about whole grains, I'm faced with a new lesson, and it's all about "old-world" grains. Here's what I'm learning.

Once only found in health food stores, these grains -- amaranth, spelt, and quinoa are a few -- are popping up on the shelves of local grocery stores. The good news, besides greater availability, is that these tasty treats may be even higher in disease-fighting nutrients than your average whole wheat, rice, and oats.

Want to give these great grains a try? Here are some tips:

• Pick bread with more than seven grains -- these are more likely to include some "old-world" alternatives, like millet and amaranth.
• Visit the rice and pasta aisle and give these a try: Boxed quinoa and Kamut pasta. Quinoa has a nutty taste, the pasta has a wheat flavor, and both cook in 20 minutes or less and can be swapped for rice or noodles in pilafs and soups.
• Try small substitutions by using these grains in foods like muffins, pancakes, even salads.
