It helps, of course, that you can eat your fill of whole grains and actually feel virtuous. (How many foods can you say that about?) Eating a variety of grains is the most enjoyable way not only to add lots of daily fiber to your diet but also to steer away from over refined carbohydrates.

There is a type of grain to fit every cooking situation. Some-like couscous and bulgur-require only steeping in boiling water for a few minutes, while others simmer without any attention for anywhere from 10 minutes to more than an hour. And none of this should be intimidating..
The Basics of Grains
Almost all grains are grasses and therefore have the same basic composition: If you were to look at a single grain and work from the outside in, you would first see the bran, very thin but tough layers that protect the interior.
Next comes the germ, which is the embryo at the base of the grain, and the endosperm, which makes up the bulk of the grain and provides food for the germ. We sometimes eat the bran and germ, which contain the most nutrients and fiber, as well as the oil that makes grains perishable, but all parts of most grains are edible, though rice, barley, and oats have an additional protective outer layer, an inedible husk or hull that must be removed before being eaten.
Milling
The process of removing parts of grains to make them edible or (by some standards) more palatable is called milling. When only the hull is removed from a grain kernel, it retains its bran and germ and is called brown, as in brown rice, or whole, as in whole oats (or, for that matter, whole wheat, which can be eaten with no milling at all).

The less grains are milled, the higher they are in both nutrients and flavor, and the longer they take to cook. This is a trade-off and a choice. (You can precook and have the best of all worlds-convenience, flavor, and nutrition.) Highly milled grains, like white rice, pearled barley, and rolled oats, contain just the endosperm, the white or light tan interior of the grain, containing little more than starch and protein.
They’re not as nutritious as whole grains, like wheat, oats, barley, quinoa, and rye-which have more fiber, micronutrients, and protein-but they’re faster cooking, a characteristic that’s easy to like.
Buying and Storing Grains
Though whole grains are increasingly available in supermarkets, your best shopping bets remain specialty supermarkets, natural food stores, and places that sell a lot of foods in bulk. International markets may be the only sources in your area for grains like farro, millet, and hominy. Mail-order and on-line shopping also offer a wide selection.
Stored in a cool, dry place, white rice, for example, will keep almost indefinitely. Brown rice and other whole grains are more sensitive; the natural oils in the bran and germ can turn rancid. Since you never know how long they’ve already been sitting on the store shelf, brown rice and other whole grains are best stored in the refrigerator, or even your freezer if possible. (No need to defrost before use.) I try to buy relatively small amounts (a pound or so) of many, many grains and use them within a year or so.

Rinsing and Draining Grains
Grains are cleaned in the milling process, so you don’t need to pick through them as you do beans. But because rice may have been coated with talc, quinoa may retain a bit of its natural saponin (a slightly bitter compound), and any grain may be gritty, I like to rinse them before cooking.
Swish them in a strainer under cold running water or put them in the pot you’re going to use, fill it with water, swirl the grains around, then pour off the water; repeat until the water is clear. You need not drain the grains well if you’re just going to boil them, but you should if you’re making pilaf, risotto, or similar dishes.
