Background

In recent years, the incidence and the fatality rate of diabetes are high, the incidence rate is in a trend of rising obviously, and the sick population is younger and younger. Diabetes, the third killer of human diseases, is a very common disease, and the incidence rate of diabetes can be as high as 5-6%. With the development of material civilization and the increasing of population aging, the incidence rate of diabetes mellitus has a remarkable rising trend, so that the treatment of diabetes mellitus is a research direction which is very worthy of research.

At present, the research directions for preventing diabetes mainly include three directions, one of which is to reduce the absorption of glucose in the intestinal tract by controlling diet or taking medicines; secondly, the use of glucose in the metabolic process is promoted; and thirdly, reducing the synthesis of glucose in the liver. The first of the three prevention directions for diabetes is the most important, the treatment of diabetes cannot be realized only by medicines, especially the diet of a patient needs to be paid special attention, the dietetic invigoration is superior to all medicinal invigorations, and the regulation, the stabilization and the control of the blood sugar level of the diabetes patient can be completely realized by a food approach, so that the blood sugar reducing medicines can be reduced or even not used, and the mental injury of the medicines to the patient is avoided.

At present, the types of milk powder on the market are many, but the milk powder contains a large amount of fat and sugar, which brings certain difficulty to the prevention of diabetes, and in addition, some milk powder with the effect of preventing diabetes is also on the market, but the milk powder can reduce blood sugar and prevent diabetes to a certain extent by adding components such as traditional Chinese medicines with the effect of reducing blood sugar into the milk powder, but the effect of reducing blood sugar is not obvious. For example, the invention with the patent number of CN101755923B discloses milk powder with the function of assisting in reducing blood sugar, which contains 0.01 to 8 parts by weight of lucid ganoderma extract, 0.01 to 8 parts by weight of lily extract, 0.01 to 4 parts by weight of dwarf lilyturf tuber extract, 0.01 to 4 parts by weight of rhizoma anemarrhenae extract and 3 to 15 parts by weight of xylitol, relative to 260 to 700 parts by weight of fresh milk or 30 to 80 parts by weight of milk powder directly obtained from milk; the milk powder has certain effect of regulating blood sugar of human body by adding traditional Chinese medicine components with blood sugar reducing effect, but the effect is not obvious.
