The necessity of this study is the increase of hypertension and diabetes patients and the burden of individual, social and national burdens as they are taking medications for life. The purpose of this study was to investigate the influence of brown rice-vegetarian diet on hypertension-diabetic patients. As a research method, data were collected using the focus group discussion method of qualitative research, and the analysis method of Colaizzi (1978) was conducted. For data collection, the study participants were divided into 2 groups and interviewed with a total of 6 people from their point of view. As a result of the study, 5 categories, 11 topics, and 85 related meanings were derived. The derived categories were 'experienced physical changes', 'recognized the importance of food', 'choose brown rice-vegetarian food', 'better health', 'Stopping high blood pressure or diabetes medication'. In conclusion, the results of this study showed that as participants chose a brown rice-vegetarian diet, blood pressure and diabetes were naturally controlled, leading to discontinuation of antihypertensive and diabetes medications. Therefore, it is thought that the individual-society-national burden can be reduced by the participants quitting the drug, and from a nursing perspective, a change in perception and awareness of the importance of diet in nursing intervention for both disease groups is expected.
