The Why: These legumes are incredibly rich in protein and low in calories, which is particularly important for active women who want rich protein sources without gaining weight. They’re also loaded with fiber, which means that lentils provide a great deal of energy without spiking blood sugar levels. According to the prestigious Cochrane Systematic Review, “When foods are eaten the body breaks them down into their components, and one component will be sugar. Different foods break down at different rates. Lentils, for instance, generate a long, gentle release of sugars, while foods like white bread send a sudden rush of sugar into the blood stream. Foods that release sugars rapidly are said to have a high glycemic index — those that release it slowly have a low glycemic index.”
Lentils also contain vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), and folate, all of which are said to have a role in increasing the production of energy in the body. According to research from Oregon State University that was published in the International Journal of Sport Nutrition and Exercise Metabolism, these micronutrients are necessary for converting proteins and sugars into energy and are also used during the production and repair of cells, including red blood cells. And if you’re physically active, according to the Oregon State researchers, “The stress on the body’s energy producing pathways during exercise, the changes in the body’s tissues resulting from training, an increase in the loss of nutrients in sweat, urine and feces during and after strenuous activity and the additional nutrients needed to repair and maintain higher levels of lean tissue mass present in some athletes and individuals may all affect an individual’s B-vitamin requirements.”
Health Perks: Aside from the fiber and B-vitamins, lentils are packed with iron (one cup has 37 percent of Daily Values), which active (and inactive) women certainly need. Iron is an essential mineral necessary for the formation of hemoglobin, which carries oxygen in the blood, and myoglobin, which carries oxygen in muscle tissue. It is also essential for the regulation of cell growth and differentiation. If you don’t get enough iron, it limits oxygen delivery to the cells, resulting in fatigue, poor work performance, decreased immunity, and, during childhood, difficulty in maintaining body temperature.
Also, as mentioned, lentils are extremely high in folate (one cup has 90 percent of Daily Values), which is widely known to reduce the risk of certain serious birth defects, such as spina bifida, and is, therefore, extremely important for women of childbearing age. But folate has many other important functions as well. It helps the body form genetic material (DNA) and blood cells and may reduce the level of the amino acid homocysteine, which has been implicated in cardiovascular disease. And, according to a recent report in the American Journal of Clinical Nutrition, folate may protect against cognitive decline in older adults.
Other important vitamins and minerals found in lentils include magnesium (one cup has 18 percent of Daily Values) and potassium (one cup contains 22 percent of Daily Values). Magnesium helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. It also helps regulate blood sugar levels, promotes normal blood pressure, and is involved in energy metabolism and protein synthesis. Potassium is necessary for muscle contractions, transmission of nerve impulses, and maintaining the delicate balance of fluid and electrolyte regulation.

Tips and Notes
- Make-Ahead Tip: Prepare through Step 3, cover and refrigerate for up to one day.
- Kitchen Tip: To cook lentils, combine 1/2 cup red or brown lentils in a medium saucepan with 1 1/2 cups water. Bring to a boil over medium-high heat; reduce heat so the lentils boil gently, cover and cook, stirring occasionally, until just tender, 12 to 18 minutes (red lentils cook more quickly than brown). Makes 1 1/2 cups.
- Kitchen Tip: To peel and dice a mango, slice both ends off the mango, revealing the long, slender seed inside. Set the fruit upright on a work surface and remove the skin with a sharp knife. With the seed perpendicular to you, slice the fruit from both sides of the seed, yielding two large pieces. Turn the seed parallel to you and slice the two smaller pieces of fruit from each side. Dice into desired size.
