Abstract

Although sugar intake did not directly lead to diabetes, the results will vary depending on age, sex, individual differences, and the nature of sugar ingested. However, the change in blood glucose level and the accumulation of fat in the body cannot neglected about the sugar intake. Also, if the sweetness recognition threshold increases, the intake of sugar may increase. Therefore, the purpose of this study was to conduct a sweetness cognitive threshold test to understand the sensitivity of the general public to sweetness. The acceptable range (sugar concentration of 2.5% or less) was 25 out of 38 participants who recognized sweetness, 65.8% of the total. Two of the 14 male participants were unrecognizable even at the sweetest concentration of 80.0%. Females had better sweetness perception threshold results than males. In the future, we think it would be good to use a questionnaire to investigate the usual eating habits and compare it with the wetness cognitive threshold test results.
