Non-Communicable Diseases (NCDs) are the highest cause of death and result in loss of productive days for sufferers and companions. To overcome this problem, the study aims to test rice bran cookies with 30% substitution on glucose levels, cholesterol levels, and triglyceride levels in experimental animals so that they can be recommended as healthy cookies low in sugar and low in fat for a snack for people with diabetes mellitus and dyslipidemia. This type of research is an experiment. Research location of the Inter-University Center Experimental Animal Laboratory (PAU) Gadjah Mada University (UGM). The initial stage is to prepare 15 male Sprague Dawley (SD) male white rats weighing 250-300 grams and in closed cages. Rats measured blood glucose levels, total cholesterol and triglycerides. Furthermore, the rats were grouped into 3 groups, and 2 groups were given an injection of streptozotocin (STZ) to make the rats diabetic. Group 1: 5 healthy rats fed a standard diet, group 2: 5 diabetic rats fed a standard diet, and group 3: 5 diabetic rats fed with rice bran cookies. Drinking water is given ad libitum and feeding is given every morning. Furthermore, weighing and analysis of blood glucose levels, total cholesterol, and triglycerides were carried out on the seventh, tenth, seventeenth, twenty-fourth, thirty-first, and thirty-eighth days. The results showed that 30% substitute bran cookies were able to reduce glucose levels, cholesterol levels, and serum triglyceride levels so that they could be recommended as a snack for people with diabetes mellitus and people with dyslipidemia.
