Corn salad, also known as field lettuce or cat's grass, is an herb from the same family as valerian, native to Navarra. These small, shiny green leaves grow wild in cold climates and are valued in the kitchen for their delicate texture and flavor. With only 14 calories per 100 grams, corn salad is a very light option for any diet. Furthermore, it is a rich source of vitamins and minerals, although its content can vary depending on the nutrient richness of the soil where it is grown. Among its main nutrients is provitamin A, also known as beta-carotene. Although corn salad does not show the characteristic orange color associated with this substance, its content in beta-carotene may help protect the body from free radicals and diseases. This provitamin is crucial, as the body can convert it into vitamin A when needed, essential for cell growth and differentiation. Corn salad also provides folic acid, a nutrient that is especially important for pregnant women, ensuring proper growth and development of the fetus. Its consumption is also recommended in cases of iron deficiency anemia and to strengthen bones due to its calcium content.
