Combine the creamy pink texture of pinto beans with a whole grain such as brown rice and you have a virtually fat-free high quality protein meal. Dried pinto beans are generally available in prepackaged containers as well as bulk bins; both canned and dried pinto beans are available throughout the year.
Pinto beans have a beige background strewn with reddish brown splashes of color. They are like little painted canvases, à la Jackson Pollack; hence their name "pinto," which in Spanish means "painted." When cooked, their colored splotches disappear, and they become a beautiful pink color.
Pinto beans are a very good source of cholesterol-lowering fiber, as are most other beans. In addition to lowering cholesterol, pinto beans' high fiber content prevents blood sugar levels from rising too rapidly after a meal, making these beans an especially good choice for individuals with diabetes, insulin resistance or hypoglycemia. When combined with whole grains such as brown rice, pinto beans provide virtually fat-free, high quality protein. But this is far from all pinto beans have to offer. Pinto beans are also an excellent source of molybdenum, a very good source of folate, and a good source of protein, vitamin B1, and vitamin B6 as well as the minerals copper, phosphorus, iron, magnesium, manganese, and potassium.
Check a chart of the fiber content in foods and you'll see legumes leading the pack. Pinto beans, like other beans, are rich in fiber. A cup of cooked pinto beans provides over 15 grams. Soluble fiber forms a gel-like substance in the digestive tract that combines with bile (which contains cholesterol) and ferries it out of the body. Research studies have shown that insoluble fiber not only helps to increase stool bulk and prevent constipation, but also helps prevent digestive disorders like irritable bowel syndrome and diverticulosis.
In a study that examined food intake patterns and risk of death from coronary heart disease, researchers followed more than 16,000 middle-aged men in the U.S., Finland, The Netherlands, Italy, former Yugoslavia, Greece and Japan for 25 years. Typical food patterns were: higher consumption of dairy products in Northern Europe; higher consumption of meat in the U.S.; higher consumption of vegetables, legumes, fish, and wine in Southern Europe; and higher consumption of cereals, soy products, and fish in Japan. When researchers analyzed this data in relation to the risk of death from heart disease, they found that higher legume consumption was associated with a whopping 82% reduction in heart attack risk!!
Pinto beans' contribution to heart health lies not just in their fiber, but in the significant amounts of folate, magnesium, and potassium these beans supply. Folate helps lower levels of homocysteine, an amino acid that is an intermediate product in an important metabolic process called the methylation cycle. Elevated blood levels of homocysteine are an independent risk factor for heart attack, stroke, or peripheral vascular disease, and are found in between 20-40% of patients with heart disease. It has been estimated that consumption of 100% of the daily value (DV) of folate would, by itself, reduce the number of heart attacks suffered by Americans each year by 10%.
Pinto beans' good supply of magnesium puts yet another plus in the column of its beneficial cardiovascular effects. Magnesium is Nature's own calcium channel blocker. When there is enough magnesium around, veins and arteries breathe a sigh of relief and relax, which lessens resistance and improves the flow of blood, oxygen and nutrients throughout the body. Studies show that a deficiency of magnesium is not only associated with heart attack but that immediately following a heart attack, lack of sufficient magnesium promotes free radical injury to the heart. Potassium, an important electrolyte involved in nerve transmission and the contraction of all muscles including the heart, is another mineral that is essential for maintaining normal blood pressure and heart function. Pinto beans are ready to promote your cardiovascular health by being a good source of this mineral, too. A one cup serving of pinto beans provides 746 mg of potassium and only 1.7 mg of sodium, making these beans an especially good choice to prevent high blood pressure and protect against atherosclerosis.
The effectiveness of potassium-rich foods such as pinto beans in lowering blood pressure has been demonstrated by a number of studies. For example, researchers tracked over 40,000 American male health professionals over four years to determine the effects of diet on blood pressure. Men who ate diets higher in potassium-rich foods, as well as foods high in magnesium and cereal fiber, had a substantially reduced risk of stroke.
In addition to its beneficial effects on the digestive system and the heart, the dietary fiber found in pinto beans helps stabilize blood sugar levels. If you have insulin resistance, hypoglycemia or diabetes, pinto beans can really help you balance blood sugar levels while providing steady, slow-burning energy. Studies of high fiber diets and blood sugar levels have shown the dramatic benefits provided by these high fiber foods. Researchers compared two groups of people with Type II diabetes who were fed different amounts of high fiber foods. One group ate the standard American Diabetic diet, which contains 24 grams of fiber/day, while the other group ate a diet containing 50 grams of fiber/day. Those who ate the diet higher in fiber had lower levels of both plasma glucose (blood sugar) and insulin (the hormone that helps blood sugar get into cells). The high fiber group also reduced their total cholesterol by nearly 7%, their triglyceride levels by 10.2% and their VLDL (Very Low Density Lipoprotein—the most dangerous form of cholesterol)levels by 12.5%.
Pinto beans are an excellent source of the trace mineral, molybdenum, an integral component of the enzyme sulfite oxidase, which is responsible for detoxifying sulfites. Sulfites are a type of preservative commonly added to prepared foods like delicatessen salads and salad bars. Persons who are sensitive to sulfites in these foods may experience rapid heartbeat, headache or disorientation if sulfites are unwittingly consumed. If you have ever reacted to sulfites, it may be because your molybdenum stores are insufficient to detoxify them.
In addition to providing slow burning complex carbohydrates, pinto beans can increase your energy by helping to replenish your iron stores. Particularly for menstruating women, who are more at risk for iron deficiency, boosting iron stores with pinto beans is a good idea—especially because, unlike red meat, another source of iron, pinto beans are low in calories and virtually fat-free. Iron is an integral component of hemoglobin, which transports oxygen from the lungs to all body cells, and is also part of key enzyme systems for energy production and metabolism. And remember: If you're pregnant or lactating, your needs for iron increase. Growing children and adolescents also have increased needs for iron.
Pinto beans are a very good source of manganese and a good source of copper, two trace minerals that are essential cofactors of a key oxidative enzyme called superoxide dismutase. Superoxide dismutase disarms free radicals produced within the mitochondria (the energy production factories within our cells).
Copper is also necessary for the activity of lysyl oxidase, an enzyme involved in cross-linking collagen and elastin, both of which provide the ground substance and flexibility in blood vessels, bones and joints.
As explained above, iron is primarily used as part of hemoglobin, the molecule responsible for transporting and releasing oxygen throughout the body. But hemoglobin synthesis also relies on copper. Without copper, iron cannot be properly utilized in red blood cells. Fortunately, Mother Nature supplies both minerals in pinto beans.
The B vitamin, thiamin participates in enzymatic reactions central to energy production and is also critical for brain cell/cognitive function. This is because thiamin is needed for the synthesis of acetylcholine, the important neurotransmitter essential for memory and whose lack has been found to be a significant contributing factor in age-related impairment in mental function (senility) and Alzheimer's disease. Alzheimer's disease is clinically characterized by a decrease in acetylcholine levels.
If you're wondering how to replace red meat in your menus, become a fan of pinto beans. These hearty beans are a good source of protein, and when combined with a whole grain such as whole wheat pasta or brown rice, provide protein comparable to that of meat or dairy foods without the high calories or saturated fat found in these foods. And, when you get your protein from pinto beans, you also get the blood sugar stabilizing and heart health benefits of the soluble fiber provided by these versatile legumes. A cup of pinto beans provides over 15 grams of protein.
Pinto beans have a beige background strewn with reddish brown splashes of color. They are like little painted canvases, à la Jackson Pollack; hence their name "pinto," which in Spanish means "painted." When cooked, their colored splotches disappear, and they become a beautiful pink color with a delightfully creamy texture.
Pinto beans and other beans such as kidney beans, navy beans and black beans are all known scientifically as Phaseolus vulgaris. They are all referred to as "common beans" probably owing to the fact that they derived from a common bean ancestor that originated in Peru.
From there, beans were spread throughout South and Central America by migrating Indian trades. Beans were introduced into Europe in the 15th century by Spanish explorers returning from their voyages to the New World. Spanish and Portuguese traders brought them to Africa and Asia.
As beans are a very inexpensive form of good protein, they have become popular in many cultures throughout the world. Pinto beans are the most highly consumed dried bean in the United States. Today, the largest commercial producers of dried common beans are India, China, Indonesia, Brazil and the United States.
Dried pinto beans are generally available in prepackaged containers as well as bulk bins. Just as with any other food that you may purchase in the bulk section, make sure that the bins are covered and the store has a good product turnover rate to ensure maximal freshness.
Whether purchasing pinto beans in bulk or in a packaged container, make sure there's no evidence of moisture or insect damage and that beans are whole and not cracked.
Canned pinto beans can be found in many markets. Unlike canned vegetables, which have lost much of their nutritional value, there is little difference in the nutritional value of canned pinto beans and those you cook yourself. Canning lowers vegetables' nutritional value since they are best lightly cooked for a short period of time, while their canning process requires a long cooking time at high temperatures. On the other hand, beans require a long time to cook whether they are canned or you cook them yourself. Therefore, if enjoying canned beans is more convenient for you, by all means go ahead and enjoy them. We would suggest looking for those that do not contain extra salt or additives. (One concern about canned foods is the potential for the can to include a liner made from bisphenol A/BPA. To learn more about reducing your exposure to this compound, please read our write-up on the subject).
Store dried beans in an airtight container in a cool, dry and dark place where they will keep for up to 12 months. If you purchase pinto beans at different times, store them separately; they may feature varying stages of dryness and therefore will require different cooking times.
Cooked pinto beans will keep fresh in the refrigerator for about three days, if placed in a covered container.
