Introduction: Obesity and arterial hypertension (AH) have reached epidemic proportions in the world. Literature suggests that hypertensive individuals have higher thresholds of salt recognition than normotensives, causing implications for taste preference and perhaps in greater intake. The salt taste sensitivity (STS) is the ability of individuals to recognize the taste of salt. The objective of this study is to assess the Body Mass Index (BMI), salt taste sensitivity (STS) and blood pressure (BP) of a group of individuals with no history of hypertension. Methods: Contemporary and crosssectional observational study that included individuals that attend Health Services, without history of hypertension, Diabetes Mellitus, previous renal disease, drug use or treatments that may alter the salt taste sensitivity. We there have been studied: BMI, STS, blood pressure (BP), and sodium in 24-hour urine. The LSGS was assessed by the method of identifying the taste of salt solutions with successive dilutions. Results and Conclusion: 70 patients were evaluated, 26 male. The average BMI of the individuals assessed obesity and 28 (40%) had the STS increased. Through the methodology used in this study, it was verified that among individuals without history of hypertension, female was predominant, average age higher than 30 years old and obesity; obese people had the STS increased, higher sodium in 24-hours urine, use of salt at the table, coffee, alcohol and smoke; and that the subgroup of individuals with increased STS, had higher systolic BP average, besides major occurrence of salt, coffee and smoke consumption.
