The invention provides engineering rice suitable for people having unbalanced diet and with a function of reducing blood glucose and a preparation method of the engineering rice. The invention relates to the engineering rice suitable for people suffering from hyperglycemia caused by unbalanced nutritional structure and the preparation method of the engineering rice. The engineering rice comprises pumpkin powder, brown rice powder, inulin, konjac gum, fishskin peptide, oat fiber, soybean protein isolate, beta-carotene and lecithin. The engineering rice is prepared by the following steps: premixing the raw materials; performing high-temperature high-pressure texturizing forming by using a double screw extruder; and drying, dedusting and packaging to obtain the engineering rice. The engineering rice has low glycemic index and low cholesterol content, has the effects of stabilizing postprandial blood glucose, improving insulin resistance and effectively improving glucose tolerance, glycosylated hemoglobin level and the like, and is suitable for people suffering from metabolic syndrome caused by diabetes.
