# Introduction he number of patients with diabetes is increasing year by year. Since the number of diabetic patients with complications is increasing, kidney dysfunction, advanced symptoms, and the number of patients requiring dialysis is increasing. As the national health burden in Japan has increased, maintaining national health insurance has become difficult. Therefore, in this study, we conducted a sweetness cognitive threshold test using a taste-disk on neighboring residents who participated in the university festival. Understanding this result can be used as data for future sweetness perception threshold tests. A sweetness cognitive threshold test performed on 38 people who participated in the university festival using TASTE-DISC. II. # Materials and Methods # a) Participants Participants were 14 males and 24 females. Table 1 shows the distribution of the participant's gender and age. We also conducted a questionnaire survey on dietary habits. There are four questions, 1) Saliva secretion, 2) Taste perception, 3) Use of restaurants and commercial food, 4) Favorite salt taste of food (Table 2). # c) Ethical review board This study conducted with the approval of the Ethics Committee (Nagoya women's university 'hito wo mochiita kennkyuu ni kansuru iinnkai'). The approval number is 30-14. # III. # Results # a) Sweetness recognition test result The age distribution of the participants was seven males in their'10S, two in their '30s, four in their '40s, one in their '60s, for a total of fourteen participants. The age distribution of the participants was five females in their 10s, ten in their '20s, five in their '40s, one in their '50s, two in their '60s, one in their '70s, for a total of 24 participants. The cognitive threshold test result for saltiness was 0.3%, the lowest concentration, and fourteen (zero male and fourteen female) participants recognized saltiness. The cognitive threshold test result for saltiness was 2.5%, the second-lowest concentration, and eleven (six male and five female) participants recognized saltiness. The cognitive threshold test result for saltiness was 10.0%, the third-lowest concentration, and eleven (six male and five female) participants recognized saltiness (see Table 3). # Table 3: Sweetness perception threshold test (TASTE DISC) results (number of participants) The acceptable range (we call normal range) was 25 participants, 65.8% of the total. Only two participants could not feel the sweetness or feel only the strong taste, 5.3% of the total (to see Table 4 and Table 5). As a result, 13 participants could not perceive the light sweetness. The age ranged from the teens to the seventies. Two participants could not recognize the sweetness at all (see Table 6). # Table 6: Breakdown of people whose salt cognition threshold test (TASTE DISC) results are outside the normal range b) Questionnaire results When asked about salivary secretion, 33 (11 males and 22 females) participants (86.8%) answered that saliva secreted well. When asked about the perception of teste, 24 (nine males and 15 females) participants (63.2%) answered that they knew the taste well. When asked about the frequency of eating out, most participants answered that they would use it 2-3 times a week. Two male participants said they were eating out every day. On the contrary, two participants answered that females rarely eat out. It turns out that males eat out more often than females. In response to questions about the usual seasoning of meals, 23 (seven males and 16 females) participants (60.5%) replied that they were eating rather heavily seasoned meals. # Discussion Participants ranged from 10s to 80s. Two male participants could not understand unless they had a high concentration of sweetness. It has reported that sweetness susceptibility changes in older 1) , and stressed conditions 2) . It also reported that sweets may be eaten too much during pregnancy 3) and quit smoking 4,5) . It also reported that the threshold for sweetness may increase by eating a lot of sweets during childhood when the taste is created 6,7,8) . From the results of this study, it was also found that males eat foods with a strong taste daily, because males use eating out more frequently than females. From these results, it found that a detailed questionnaire survey on dietary habits needed in the future. We would like to ask the participants in more detail about the sweetness of their everyday meals. Preventing diabetes will prevent many other related diseases. We would like to continue to educate people on low-sugar diets that can prevent postprandial hyperglycemia. In the future, we would like to continue to provide menus and recipes that have low sweetness, low sugar content, or high dietary fiber that moderates digestion and absorption. V. # Conclusions A sweetness cognitive threshold test performed on 38 people who participated in the university festival using TASTE-DISC. Females perceived sweetness at a lower threshold than males. Two of the 14 male participants were unrecognizable even at the sweetest concentration of 80.0%. 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. 1Year 20209Volume XX Issue VIII Version ITMedical Research ( D D D D ) Kb) Assessment of sweet taste identification Participants were subjected to a sweet cognitive threshold test using TASTE-DISC (manufactured by Sanwa Chemical Laboratory Co., LTD).
