Relationship Between Taurine Intake and Cardiometabolic Risk Markers in Korean Elderly

Taurine can suppress the creation of lipid hydroperoxide and decrease the level of total cholesterol and triglyceride in the blood. This study aimed to analyze the relationship between biochemical indicators associated with cardiometabolic disease and taurine intake in elderly people. Subjects of this study were those participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2016, aged over 75 years old. Data of dietary intake were collected through 24-h dietary recall method, and for nutrient analysis, the taurine intake was divided into quadrants. Mean values of taurine intake were 237.8 ± 17.5 mg/day in men and 157.5 ± 12.4 mg/day in women. Both men and women in the quadrants with the higher level of taurine intake appeared to show high intake levels of energy, protein, fat, total cholesterol, calcium, phosphorus, sodium, potassium, riboflavin, and niacin. As a result of relationship analysis between taurine intake and cardiometabolic risk markers (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol, blood pressure, blood glucose, and atherogenic index), taurine intake showed a significantly negative relation with AI in men but showed a positive relation in women with DBP.
