Hypertension is a health issue that can be controlled through lifestyle modifications, including the implementation of the DASH diet. This study aims to determine the effect of DASH diet education on the knowledge level and blood pressure of hypertensive patients at Rumah Sakit Islam Jakarta Cempaka Putih. This study employed a Pre-Experimental One Group Pretest-Posttest design with a sample size of 28 respondents selected using purposive sampling. Education was provided through lectures and leaflets for 30 minutes. Data were collected using knowledge questionnaires and blood pressure measurements before and after the intervention. Data were analyzed using the Shapiro-Wilk and Wilcoxon tests since some of the data were not normally distributed. The results showed a significant increase in knowledge (p = 0.001) as well as a significant decrease in both systolic and diastolic blood pressure (p = 0.001). In conclusion, DASH diet education is effective in increasing knowledge and helping to lower blood pressure in hypertensive patients.
