Health Benefits of Lettuce
Although all varieties of lettuce are very low in calories, they do not all rank the same in nutritional value.
Though Romaine provides decent nutrition, iceberg lettuce does not, so to make the ultimate nutritious salad, use plenty of leafy greens. Wonderfully flavored greens like radicchio, arugula, endive, chicory, and escarole make a salad stand out in taste and nutrition. Some greens back up their fat-fighting bulk with a decent amount of fiber.
The 2005 Dietary Guidelines for Americans recommend eating about 2 cups of vegetables each day. It takes two cups of raw greens to equal one cup of veggies, according to the Guidelines.
Health Benefits of Lettuce
The darker the color of the salad green, the more nutritious it is. Beta-carotene is the chief disease-fighting nutrient found in the darker-colored greens. As an antioxidant, it battles certain cancers, heart disease, and cataracts. A dark-green color also indicates the presence of folic acid, which helps prevent neural-tube birth defects in the beginning stages of pregnancy. Researchers are uncovering other important contributions folic acid has to offer to your well-being, like its role in the prevention of heart disease and inflammation. Most salad greens are also notable sources of vitamin C, potassium, and fiber.
