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.
Lower Cholesterol
Lentils help to reduce blood cholesterol since it contains high levels of soluble fiber. Lowering your cholesterol levels reduces your risk of heart disease and stroke by keeping your arteries clean.
Heart Health
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.
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!!Digestive Health
Research studies have shown that insoluble dietary fiber found in lentils helps prevent constipation and other digestive disorders like irritable bowel syndrome and diverticulosis.A single cup of cooked lentils contains 16 grams of dietary fiber, or 63 percent of the U.S. Department of Agriculture's recommended daily allowance of fiber for an adult man or woman on a 2,000-calorie diet. Lentils contain some soluble fiber, but are an outstanding source of insoluble fiber. According to The Cancer Project, a diet that includes plenty of insoluble fiber can regulate bowel movements, promote digestive system health and may significantly decrease the risk of colon, breast, throat and esophageal cancer. Fiber-rich foods like lentils may also help prevent stroke, heart disease, diabetes, high blood cholesterol and hypertension.
Stabilized Blood Sugar
Adding to the many benefits of fiber, soluble fiber traps carbohydrates, slowing down digestion and stabilizing blood sugar levels. This can be especially helpful for those with diabetes, insulin resistance or hypoglycemia.
Good Protein
Of all legumes and nuts, lentils contain the third-highest levels of protein. 26 percent of lentil’s calories are attributed to protein, which makes them a wonderful source of protein for vegetarians and vegans.
Increases 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.
Weight Loss
Cooked lentils provide 18 grams of protein per cup, with less than 1 gram of fat, negligible saturated fat and no cholesterol. When compared to beef, poultry and fish, all of which are good sources of protein but contain much higher amounts of saturated fat and cholesterol, the Harvard School of Public Health names legumes such as lentils a better protein choice. A 2012 study published in the "Archives of Internal Medicine" reported that substituting lean protein sources like beans for red meat could lower your overall risk of dying from most diseases, including cancer and heart disease.
Lentils do not contain all of the amino acids required by the body for protein synthesis. Combine them with a grain like rice or whole-wheat bread for a meal providing complete protein.
One cup of cooked lentils only contains about 230 calories, but still leaves you feeling full and satisfied.
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.
