Compared to other types of dried beans, lentils are relatively quick and easy to prepare. They readily absorb a variety of wonderful flavors from other foods and seasonings, are high in nutritional value and are available throughout the year.
Lentils are legumes along with other types of beans. They grow in pods that contain either one or two lentil seeds that are round, oval or heart-shaped disks and are oftentimes smaller than the tip of a pencil eraser. They may be sold whole or split into halves with the brown and green varieties being the best at retaining their shape after cooking.

Health Benefits
Lentils, a small but nutritionally mighty member of the legume family, are a very good source of cholesterol-lowering fiber. Not only do lentils help lower cholesterol, they are of special benefit in managing blood-sugar disorders since their high fiber content prevents blood sugar levels from rising rapidly after a meal. But this is far from all lentils have to offer. Lentils also provide good to excellent amounts of six important minerals, two B-vitamins, and protein—all with virtually no fat. The calorie cost of all this nutrition? Just 230 calories for a whole cup of cooked lentils. This tiny nutritional giant fills you up—not out.Lentils—A Fiber All Star
Check a chart of the fiber content in foods; you'll see legumes leading the pack. Lentils, like other beans, are rich in dietary fiber, both the soluble and insoluble type. Soluble fiber forms a gel-like substance in the digestive tract that snares 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.Love Your Heart—Eat Lentils
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 legumes were associated with a whopping 82% reduction in risk!!
A study published in the Archives of Internal Medicine
confirms that eating high fiber foods, such as lentils, helps prevent
heart disease. Almost 10,000 American adults participated in this study
and were followed for 19 years. People eating the most fiber, 21 grams
per day, had 12% less coronary heart disease (CHD) and 11% less
cardiovascular disease (CVD) compared to those eating the least, 5 grams
daily. Those eating the most water-soluble dietary fiber fared even
better with a 15% reduction in risk of CHD and a 10% risk reduction in
CVD.
Lentils' contribution to heart health lies not just in their fiber, but in the significant amounts of folate and magnesium
these little wonders supply. Folate helps lower levels of homocysteine,
an amino acid that is an intermediate product in an important metabolic
process called the methylation cycle. When folate (as well as vitamin
B6) are around, homocysteine is immediately converted into cysteine or
methionine, both of which are benign. When these B vitamins are not
available, levels of homocysteine increase in the bloodstream—a bad idea
since homocysteine damages artery walls and is considered a serious
risk factor for heart disease.
Lentils' magnesium puts yet another plus in the column of its beneficial cardiovascular effects. Magnesium is Nature's own calcium channel blocker. When enough magnesium is 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. Want to literally keep your heart happy? Eat lentils.
Lentils Give You Energy to Burn While Stabilizing Blood Sugar
In addition to its beneficial effects on the digestive system and the heart, soluble fiber helps stabilize blood sugar levels. If you have insulin resistance, hypoglycemia or diabetes, legumes like lentils 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 2 diabetes who were fed different amounts of high fiber foods. One group ate the standard American Diabetic diet, which contains with 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%.Iron for Energy
In addition to providing slow burning complex carbohydrates, lentils can increase your energy by replenishing your iron stores. Particularly for menstruating women, who are more at risk for iron deficiency, boosting iron stores with lentils is a good idea—especially because, unlike red meat, another source of iron, lentils are not rich in fat and calories. 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.Description
Lentils are legumes, seeds of a plant whose botanical name is Lens ensculenta. They grow in pods that contain either one or two lentil seeds.Lentils are classified according to whether they are large or small in size with dozens of varieties of each being cultivated. While the most common types in the United States are either green or brown, lentils are also available in black, yellow, red and orange colors. These round, oval or heart-shaped disks are small in size, oftentimes smaller than the tip of a pencil eraser. They are sold whole or split into halves.
The different types offer varying consistencies with the brown and green ones better retaining their shape after cooking, while the others generally become soft and mushy. While the flavor differs slightly among the varieties, they generally feature a hearty dense somewhat nutty flavor.
History
Lentils are believed to have originated in central Asia, having been consumed since prehistoric times. They are one of the first foods to have ever been cultivated. Lentil seeds dating back 8000 years have been found at archeological sites in the Middle East. Lentils were mentioned in the Bible both as the item that Jacob traded to Esau for his birthright and as a part of a bread that was made during the Babylonian captivity of the Jewish people.For millennia, lentils have been traditionally been eaten with barley and wheat, three foodstuffs that originated in the same regions and spread throughout Africa and Europe during similar migrations and explorations of cultural tribes. Before the 1st century AD, they were introduced into India, a country whose traditional cuisine still bestows high regard for the spiced lentil dish known as dal. In many Catholic countries, lentils have long been used as a staple food during Lent. Currently, the leading commercial producers of lentils include India, Turkey, Canada, China and Syria.
How to Select and Store
Lentils 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 containing the lentils are covered and that the store has a good product turnover so as to ensure its maximal freshness. Whether purchasing lentils in bulk or in a packaged container, make sure there is no evidence of moisture or insect damage and that the lentils are whole and not cracked.Canned lentils can be found in some grocery stores and most natural foods markets. Unlike canned vegetables, which have lost much of their nutritional value, there is little difference in the nutritional value of canned lentils 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 lentils 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 lentils in an airtight container in a cool, dry and dark place. Stored this way, they will keep for up to 12 months. If you purchase lentils at different times, store them separately since they may feature varying stages of dryness and therefore will require different cooking times. Cooked lentils will keep fresh in the refrigerator for about three days if placed in a covered container.
Tips for Preparing and Cooking
Tips for Preparing Lentils
Lentils can be prepared the day of serving since they do not need to be presoaked. Before washing lentils you should spread them out on a light colored plate or cooking surface to check for, and remove, small stones or debris. After this process, place the lentils in a strainer, and rinse them thoroughly under cool running water.The Healthiest Way of Cooking Lentils
To boil lentils, use three cups of liquid for each cup of lentils. Lentils placed in already boiling water will be easier to digest than those that were brought to a boil with the water. When the water returns to a boil, turn down the heat to simmer and cover. Green lentils usually take 30 minutes, while red ones require 20 minutes.These cooking times can be slightly adjusted depending upon the final use. If you are going to be serving lentils in a salad or soup and desire a firmer texture, remove them from the stove top when they have achieved this consistency—typically 5-10 minutes earlier than their usual cooking time. If you are making dal or some preparation that requires a mushier consistency, achieving this texture may take an additional 10-15 minutes.

Individual Concerns
Lentils and Purines
Lentils contain naturally-occurring substances called purines. Purines are commonly found in plants, animals, and humans. In some individuals who are susceptible to purine-related problems, excessive intake of these substances can cause health problems. Since purines can be broken down to form uric acid, excess accumulation of purines in the body can lead to excess accumulation of uric acid. The health condition called "gout" and the formation of kidney stones from uric acid are two examples of uric acid-related problems that can be related to excessive intake of purine-containing foods. Yet, recent research has suggested that purines from meat and fish increase risk of gout, while purines from plant foods fail to change the risk. For more on this subject, please see 'What are purines and in which foods are they found?"Nutritional Profile
Lentils are an excellent source of molybdenum and folate. They are a very good source of dietary fiber and manganese and a good source of iron, protein, phosphorus, copper, thiamin and potassium.For an in-depth nutritional profile click here: Lentils.
In-Depth Nutritional Profile
In addition to the nutrients highlighted in our ratings chart, an in-depth nutritional profile for Lentils is also available. This profile includes information on a full array of nutrients, including carbohydrates, sugar, soluble and insoluble fiber, sodium, vitamins, minerals, fatty acids, amino acids and more.Introduction to Food Rating System Chart
In order to better help you identify foods that feature a high concentration of nutrients for the calories they contain, we created a Food Rating System. This system allows us to highlight the foods that are especially rich in particular nutrients. The following chart shows the nutrients for which this food is either an excellent, very good, or good source (below the chart you will find a table that explains these qualifications). If a nutrient is not listed in the chart, it does not necessarily mean that the food doesn't contain it. It simply means that the nutrient is not provided in a sufficient amount or concentration to meet our rating criteria. (To view this food's in-depth nutritional profile that includes values for dozens of nutrients - not just the ones rated as excellent, very good, or good - please use the link below the chart.) To read this chart accurately, you'll need to glance up in the top left corner where you will find the name of the food and the serving size we used to calculate the food's nutrient composition. This serving size will tell you how much of the food you need to eat to obtain the amount of nutrients found in the chart. Now, returning to the chart itself, you can look next to the nutrient name in order to find the nutrient amount it offers, the percent Daily Value (DV%) that this amount represents, the nutrient density that we calculated for this food and nutrient, and the rating we established in our rating system. For most of our nutrient ratings, we adopted the government standards for food labeling that are found in the U.S. Food and Drug Administration's "Reference Values for Nutrition Labeling."
