Reasons why you should NOT remove the slime from nopales
Although its viscous consistency is often a turn-off for some people, the gelatinous substance released by the cactus (commonly known as slime) has remarkable qualities in both the health and industrial fields. Although many seek to remove it when preparing this vegetable, various studies suggest that its consumption can be highly beneficial.
The nopal, a plant belonging to the cactus family, is native to Mexico and has established itself as a a symbol of its biodiversity, according to data from the Ministry of Agriculture and Rural Development. In addition to its ecological importance, it is considered a staple in traditional Mexican cuisine. Its versatility allows it to be included in boiled or roasted dishes, stews, salads, juices, soups, and even in dehydrated or sweet versions.
From a nutritional standpoint, this vegetable stands out for its high fiber, mineral, and vitamin content, making it a functional food. The Center for Food and Development Research (CIAD) highlights that Its slime or mucilage is composed mainly of soluble fiber, which aids digestion and can improve intestinal transit.
In the words of Jaime Lizardi Mendoza, a researcher at CIAD's Animal Origin Food Technology Coordination, "mucilage is composed of soluble fiber, which is key to the proper functioning of the digestive system." This property not only benefits the intestinal system, but also helps control blood glucose levels and reduce LDL cholesterol, known as “bad” cholesterol.
In addition to its impact on nutrition, this substance has potential applications in other sectors. According to David Quintanar Guerrero, a researcher in nanotechnology applied to biological systems at the Cuautitlán School of Higher Education, nopal slime could be used in the pharmaceutical field. Thanks to its characteristics as a swellable polymer, "it can be used to treat ulcerative esophagitis, colon problems, damage to the mucosa of the gastrointestinal tract, and gastric reflux, among other conditions."
The researcher emphasizes that the interest in harnessing all the elements of the cactus is due to its wide geographic distribution throughout Mexico, which makes it a sustainable and accessible source for various industrial uses.
In the construction field, mucilage has also played a relevant role since ancient times. Its ability to retain moisture and its compatibility with fats made it ideal for the production of stucco, a traditional covering used in homes since pre-Hispanic times.
On the other hand, it's important to consider that, although cooked nopal remains nutritious, some of its properties can be altered by heat. As Lizardi Mendoza points out, the cooking process modifies its protein structure and reduces its water content, so eating it raw may be a better option if you want to maximize its benefits.
