Factors which relate salt intake and taste sensitivity in university female students Tsuneo Ogawa1 , Kumiko Kawakita2 and Youichi Komatsu2. 1. Laboratory of Physiology , 2 Laboratory of Nutritional Science, Department of Nutrition Management, Minami Kyushu University, 5-1-2 Kirishima, Miyazaki, 880-0032 Japan Received October 11, 2012; Accepted January 29, 2013. The number of people who has obesity or hypertension has become increased recently, which are caused partly by excess sugar or salt intake.

2 Recently many people tend to eat out or buy delicatessens, meals which are ready to eat. Because these food tend to be heavily seasoned, if we continue to eat these meals, we used to strong tastes, and the taste sensitivity may decrease, which causes excess salt and sugar intake. Seventy-six university female students who study nutrition management are enrolled in this research. Students are instructed to calculate 24 hour salt intake and urine salt excretion by using a test paper. Body weight (BW), body mass index (BMI), per cent fat and blood pressure were measured.

3 Taste sensitivity was measured by detection and rec- ognition threshold after tasting different concentration of salty, sweet, sour, bitter and savory so- lutions. A questioner for the taste preference was conducted. An average salt intake was per day and urinary salt excretion was g per day. Salt intake was positively correlated with salt excretion to urine. The students who have high BW, BMI and per cent fat showed high salt excre- tion to the urine. The taste sensitivity test revealed that the students who have low taste sensitivity for salt and sweet showed high systolic and diastolic blood pressure.

4 These results suggest that high salt intake and low taste sensitivity are related to body weight and blood sugar. Therefore it is important to reduce sugar and salt intake in the daily meal during young age, which may help to prevent future obesity and hypertension. Key words: taste sensitivity, salt intake, blood pressure, body weight.. 24 . 32 INTERSALT .. 2 1 Cook Framingham Heart Study . 2 mmHg . 17 % . 15 % 6 % . 880 -0032 5 1 -2 . 2 .
