Plants that have a low glycemic index, such as corn, can be an alternative food consumed by the public to prevent blood sugar levels from rising. Corn is not only low in the glycemic index but also rich in dietary fiber, fe, and beta-carotene (provitamin A). This study aims to examine the carbohydrate content and glycemic index (GI) of sweet corn milk (Zea mays saccarata L). This research uses descriptive quantitative analysis to describe the results of corn milk index values. This research was conducted in the Laboratory of Biochemistry, Department of Biology, Universitas Negeri Gorontalo, involving 8 respondents who met the respondent criteria. The criteria for the respondents in this study were (1) having a normal average body mass (BMI) = (18.5-25 kg/m2), (2) having no history of diabetes, (3) having a healthy body, and (4) being also not taking drugs. The glycemic index value was obtained by comparing the area under the curve between the reference food and the test food and then multiplying by 100. Based on the results of the study, the carbohydrate content of sweet corn milk was 8.79 g/100 mL, and the glycemic index (GI) value of sweet corn milk (Zea mays saccarata L) was 20.81. Based on these results, sweet corn milk (Zea mays saccarata L) belongs to the low glycemic index group.
