Abstract/Resumen: Dietary zinc (Zn) is an essential trace element that determines the incidence of obesity and its metabolic abnormalities. However, its bioavailability is affected by other nutritional factors involved in its absorption (facilitators and inhibitors). Herein we aimed at determining the dietary consumption of Zn and modulators of its absorption (facilitators/inhibitors) in a population of adults, of both genders between 18 and 59 years-old, residing in the Downtown District of the Capital City of San Luis in 2018. A validated food frequency questionnaire was used to evaluate dietary Zn consumption, as well as inhibitors (calcium, iron and fiber) and facilitators (proteins) of its absorption. The variables studied were gender, age group (young adult and mature adult), consumption of dietary zinc, calcium, iron and proteins. The dietary Zn consumption was insufficient in 35.67 % of the sample population. Regarding the consumption of inhibitors of Zn absorption, it was observed that dietary calcium intake was high in both young and mature adults. The most consumed sources of calcium were milk (49.43 %) and soft cheeses (22.40 %). It was observed that the intake dietary iron was optimal only in 6.25 % of mature women, and within its source foods, meat was the one with the highest intake (37.45 %). Fiber presented an insufficient consumption for young women, 72.73 %. The most consumed foods with high content of dietary Zn were potatoes (14.95 %) and tomatoes (14.50 %). However, mature adult women had an insufficient intake of dietary proteins, observing that among the most consumed protein source foods were red meats (46.61 %). The population studied had a sufficient consumption of dietary Zn, but a high consumption of dietary inhibitors of Zn absorption. This pattern may impact the prevalence of obesity and its associated metabolic abnormalities, consequently nutritional advice is needed in our population.
