4. The hypoglycemic mechanism of probiotics
Research shows that the mechanism of action of probiotics in regulating diabetes may include the following pathways: (1) regulating blood sugar by increasing adiponectin levels; (2) regulating blood sugar by inducing the secretion of glucagon-like peptide-1 (GLP-1); (3) Regulate blood sugar by improving insulin resistance; (4) Regulate blood sugar by reducing inflammation levels; (5) Regulate blood sugar by enhancing immunity; (6) Regulate blood sugar by improving intestinal flora. Among them, inducing GLP-1 secretion is an important way for probiotics to regulate blood sugar. Therefore, we will further analyze the mechanism of GLP-1 regulating blood sugar.
5. GLP-1 hypoglycemic mechanism
GLP-1 is an incretin-hypoglycemic hormone that can induce the production of insulin inhibit obesity and alleviate type 2 diabetes. In recent years, targeted mining and screening of probiotics that can secrete GLP-1 have gradually become a research focus.
GLP-1 hypoglycemic principle: repairs the function of pancreatic beta cells, stimulates pancreatic beta cell division, and promotes insulin secretion; prolongs the transmission time of hunger signals from intestinal cells to nerve centers, delays gastric emptying, and reduces appetite; inhibits liver glucose Xenobiotics promote the uptake of glucose by the heart, reduce glucagon secretion, decrease the level of glucose reabsorption in the kidneys, and lower blood sugar concentrations.
6. Isolation and screening of probiotics
Beneficial bacteria were isolated and screened from traditional fermented foods such as kimchi, and the 16S rDNA gene sequence was used to confirm that the obtained strains were safe and reliable and would not cause harm to the human body. By comparing the differences of strains in promoting GLP-1 secretion in rats, 4 strains of probiotics with potential hypoglycemic effects were initially screened, and then compared with their tolerance to gastric acid and bile salts and mucosal adhesion, and re-screened to obtain Lactobacillus plantarum HH-LP 56 and Lactobacillus paracasei HH-LP 58 are two probiotic strains that can both lower blood sugar and colonize well in the body.
7. Verification of hypoglycemic effect
First, a diabetic rat model is established. The rats are fed with high-fat and high-sugar feed for 8 weeks to increase their blood sugar. Then streptozotocin is injected once to destroy the β-cells that secrete insulin to establish type 2 diabetic rats. Model. The experimental rats were divided into normal group, model group (sick mice), positive drug group (metformin group), high-dose compound probiotic group (90 mg/kg/d), and low-dose compound probiotic group (90 mg /kg/d). Experimental mice were observed by intragastric administration for 4 weeks, and the GLP induced by different doses of probiotics was compared by detecting fasting blood glucose, GLP-1 and PYY (peptide tyrosine) contents in serum, and colonic GLP-1 protein levels. -1 ability to secrete.
Note: The bacterial powder used in the high-dose compound probiotic group has a viable count of 40 billion (2.0×1010 CFU/g HH-LP 56 and 2.0×1010 CFU/g HH-LP 58). The bacterial powder used in the low-dose compound probiotic group The viable bacterial count is 4 billion (2.0×109 CFU/g HH-LP 56 and 2.0×109 CFU/g HH-LP 58).
The test results are as follows:

Compared with the normal group, the serum GLP-1 and PYY contents of rats in the model group were significantly reduced. Compared with the model group, the GLP-1 and PYY contents of rats in the metformin group, low-dose compound probiotic group, and high-dose compound probiotic group increased significantly.

Figure 1 Effect of compound probiotics on rat colon GLP-1 protein levels
Compared with the normal group, the GLP-1 protein level in the colon of rats in the model group was significantly down-regulated; compared with the model group, the GLP-1 protein level of rats in the metformin group, low-dose compound probiotic group, and high-dose compound probiotic group was significantly increased.
After administrating 4.0×1010CFU/g of compound probiotic powder (90 mg/kg/d) into the rats in the model group, the fasting blood glucose and GLP-1 levels in serum and GLP-1 protein in the colon were measured. Level, the results showed that the probiotic strains Lactobacillus plantarum HH-LP 56 and Lactobacillus paracasei HH-LP 58 showed a strong ability to induce GLP-1 secretion, indicating their potential to reduce blood sugar in diabetic patients.

8. Human dose conversion
The recommended daily probiotic intake per kilogram for rats is 90 mg×4.0×1010CFU/g, which is 3.6×109CFU;
Converted based on a body weight of 70 kg, the equivalent dose in rats is equivalent to 6.3 times that of a human body. The recommended daily probiotic intake for an adult weighing 70 kg is 3.6×109CFU÷6.3×70 kg, that is, 4.0×1010CFU.
9. Analysis of excipients
Momordica charantin (peptides, polysaccharides, steroidal saponins): repairs damaged pancreatic beta cells, improves insulin levels and sensitivity; inhibits glucose absorption by inhibiting glucosidase, and inhibits the activity of disaccharides to exert a hypoglycemic effect.
Green tea essence: Tea polyphenols, tea polysaccharides, tea pigments, vitamins, and certain mineral elements in tea have a certain inhibitory effect on the rise of blood sugar. The tea polyphenols in green tea have the functions of protecting pancreatic beta cells, antioxidants, and scavenging. Function of free radicals.
Inulin and fructooligosaccharides: commonly used prebiotics to promote the growth and metabolism of probiotics in the body.
