This one is pretty easy, as long as you don’t let food marketers trick you. It can be readily found in bread and pasta products, but make sure the label says “100 percent whole wheat.” Terms like “multigrain” and “wheat” don’t cut it. As when you’re shopping for any whole-grain product, look at the ingredients and make sure the whole grain is at or near the top of the list. Each serving should contain at least 2 or 3 grams of fiber

Oats are particularly rich in avenanthramide, an antioxidant that protects the heart. When you’re shopping for this whole grain, whether you see the word “whole” or not doesn’t matter the way it does with wheat products. Oats in the ingredients list mean the product is made from whole oats. But, if you are buying something like instant oatmeal, avoid those that contain high-fructose corn syrup. Studies have found that it was a source of mercury contamination in oatmeal. We suggest sticking to the good old-fashioned unsweetened kind and mixing in a little fruit or honey.

When you choose white rice over brown, around 75 percent of its nutrients—including nearly all the antioxidants, magnesium, phosphorus, and B vitamins contained in the healthy bran and germ—are left on the milling-room floor. Always opt for brown rice, which includes brown aromatic varieties like basmati and jasmine. Get even more exotic with red and black rice, both of which are considered whole grains and are high in antioxidants. Though technically a grass, wild rice is also considered a whole grain and is rich in B vitamins, such as niacin and folate.

According to nutritional research from the nonprofit The Organic Center, rye has more nutrients per 100-calorie serving than any other whole grain. It has four times more fiber than standard whole wheat and provides you with nearly 50 percent of your daily recommended amount of iron. The problem is, most rye and pumpernickel bread in this country is made with refined flours. Be persistent and look for “whole rye” topping the ingredients list to get the healthy benefits.

Yes, freekeh has a crazy name, but it has very serious benefits. This Arabic grain is a low-carb form of ancient wheat that has up to four times more fiber than brown rice. Freekeh kernels are harvested while they’re young and then roasted. They contain more vitamins and minerals, such as immune-boosting selenium, than other grains. Once in your stomach, freekeh acts as a prebiotic, stimulating the growth of healthy bacteria that aid digestion. (This is different than a probiotic, which is a beneficial live bacteria you consume). Look for it in Middle Eastern markets or natural-food stores.

Eating a half-cup of whole barley regularly during a 5-week period cut participants’ cholesterol levels by nearly 10 percent when compared to other participants who went without barley in a USDA study. Add raisins or dried apricots to quick-cooking barley and serve it as a side dish. Just make sure it’s whole-grain barley, not “pearled,” which means the bran and germ have been removed.

This common pancake whole grain is one of the whole grains many people living with celiac disease can tolerate (others include quinoa, amaranth, and sorghum). And it’s one of the best grain-based sources of magnesium, a wonder mineral that does everything from ease PMS symptoms to improve nerve functioning; and manganese, which boosts brain power. And thank goodness for that, because who doesn’t enjoy a good buckwheat pancake from time to time?

For all practical purposes, bulgur is considered a whole grain, even though up to 5 percent of its bran may be removed during processing. It’s so good for you, though, we’re putting it on the list. The grain, which is used to make tabbouleh salad, is a great source of iron and magnesium. The fiber and protein powerhouse (a cup contains nearly 75 percent of the dietary fiber you need for the day, and 25 percent of the protein you should get) can be used in salads or tossed in soups. And it cooks in only a few minutes.

Though it’s technically a seed and not a grain, this ancient South American power food is packed with more protein than any other grain, and each uncooked cup of the stuff (about three servings) has 522 milligrams of omega-3 fatty acids. Your family will likely enjoy its light, nutty flavor for a change of pace at the dinner table. And it keeps well, so makes an easy make-ahead lunch to pack to work or school. (See the video below for how to do a one-pan make-ahead meal with quinoa, salmon, and roast veggies.)
