Choosing and cooking with beans
A healthy choice
With the exception of peanuts and soy, all beans are very low in fat and good sources of fiber, protein, folate and other B vitamins, and the minerals magnesium, potassium and iron. Light-colored beans are higher in calcium, darker beans are higher in iron. Beans also provide an array of “phytochemicals,” natural plant compounds that promote protection against chronic and degenerative diseases, including heart disease, cancer and diabetes. The fiber — particularly the soluble fiber — may help reduce the risk of diabetes, and also may help lower blood cholesterol levels. Try different varieties to enjoy their unique flavors and colors in different dishes, hot or cold.
Simple and Satisfying
Beans are among the healthiest, most economical, versatile and delicious foods. They’ve nourished us for thousands of years and are winning new fans every day.
Preparing dry beans
For best digestion and to shorten cooking time, most beans benefit from pre-soaking. Smaller beans, including adzuki, mung, lentils, black-eyed peas and split peas, generally need no pre-soaking but are more easily digested if soaked, drained and cooked in fresh water until very tender. This substantially reduces the effect of starches that promote intestinal gas during digestion.
Sort and rinse: Discard shriveled beans or small stones; rinse in cool water and drain.
Quick soak: For each cup of rinsed beans, add three to four cups water to a heavy cooking pot and bring to a boil for five minutes. Turn off heat, cover and let stand for one hour, then drain.
Longer soak: For each cup of rinsed beans, add three to four cups water and soak eight to 12 hours, then drain.
Power food
One half-cup serving of beans, peas or lentils (or one-third cup, if mashed, refried or pureed) provides about eight grams of protein and eight grams of fiber. The amount of protein in beans is reliable and easily maximized by simply including foods such as nuts, seeds and whole grains in a meal.
Stovetop cooking
For best digestion and to shorten cooking time, most beans benefit from pre-soaking. Smaller beans, including adzuki, mung, lentils, black-eyed peas and split peas, generally need no pre-soaking but are more easily digested if soaked, drained and cooked in fresh water until very tender. This substantially reduces the effect of starches that promote intestinal gas during digestion. Sort and rinse: Discard shriveled beans or small stones; rinse in cool water and drain. Quick soak: For each cup of rinsed beans, add three to four cups water to a heavy cooking pot and bring to a boil for five minutes. Turn off heat, cover and let stand for one hour, then drain. Longer soak: For each cup of rinsed beans, add three to four cups water and soak eight to 12 hours, then drain.
Pressure cooking
You may use soaked or unsoaked beans. Soaked beans cook quicker and are more digestible. Add two cups water or broth for each cup soaked beans, or three cups water for each cup unsoaked beans. It’s wise to add a tablespoon or two of cooking oil to the pressure cooker, as oil blocks potential clogging of pressure vents from foaming beans. It’s unwise to pressure cook split peas, lentils or lima beans, all of which foam heavily. In general, pressure-cooked beans save time and are more tender, flavorful and digestible.
Crockpot cooking
Whether using presoaked or unsoaked beans, always start by boiling beans for five minutes, then transfer to the crockpot and set on either low or high, noting manufacturer’s recommendation and/or your preferred time for finished beans.

For better digestibility
- To help tenderize beans and promote digestibility, use seasonings in bean dishes such as bay leaves, cilantro, coriander, cumin, epazote, fennel, garlic, ginger and peppers.
- Add a six-inch piece of dried Japanese seaweed called kombu to the cooking pot. It can be snipped into small pieces adding nutrients but no flavor or color. If preferred, leave kombu whole and remove after cooking.
- Research indicates that many people find beans become markedly more digestible when they gradually increase portions of well-cooked varieties over several weeks.
A tablet of an enzyme product, such as Beano®, can be taken during a meal of beans and may prove useful if intestinal discomfort continues to be a problem.
