Description

Technical Field

[0001] The invention belongs to the technical field of supplementary food, and particularly relates to a supplementary food for diabetics and a preparation method thereof. Background Art

[0002] Diabetes is one of the most common and life-threatening chronic diseases. According to the 2021 estimate of the International Diabetes Federation (IDF), 537 million adults aged 20 to 79 years worldwide (10.5% of all adults in this age group) suffer from diabetes, and type 2 diabetes (T2DM) (insulin resistance) accounts for 90%. Unhealthy diets and sedentary lifestyles among young people have led to an increase in obesity, and the incidence of T2DM is on the rise among children and young people. If not managed and controlled, complications caused by diabetes, such as retinopathy, diabetic nephropathy, and neuropathy, can be life-threatening.

[0003] At present, for the increasing number of diabetic patients, maintaining their blood sugar stability and avoiding large fluctuations is the key to treatment, and the rational selection of staple foods with low blood sugar response is the focus of diabetic dietary treatment.

[0004] However, the current drug treatment for diabetes mainly includes oral hypoglycemic drugs and insulin therapy. There are many types of oral hypoglycemic drugs, such as sulfonylurea drugs (increasing insulin sensitivity by improving insulin receptor defects), metformin (increasing peripheral tissue uptake and utilization of glucose and reducing liver glucose production), α-glucosidase inhibitors (delaying carbohydrate absorption), etc. These drugs play an important role in controlling blood sugar, but long-term use may also bring some side effects, such as hypoglycemia risk and gastrointestinal discomfort. Insulin therapy controls blood sugar by exogenous insulin supplementation. For patients with type 1 diabetes or some severe type 2 diabetes, insulin therapy is necessary, but improper use may also lead to problems such as hypoglycemia or weight gain. In addition, if traditional Chinese medicine is currently used for treatment, most of the traditional Chinese medicine decoctions will irritate the gastrointestinal tract, and the patient's medication compliance is poor, making it difficult for patients to persist in long-term use. When using combination chemical drugs for treatment, the drug cost is high and it is difficult to promote and apply. If some precious famous medicinal materials are used, it is also difficult for patients to afford it all the time. Summary of the invention

[0063] The gorgon fruit of the present invention is a dried mature seed of a plant of the Nymphaeaceae family and is widely used in traditional Chinese medicine and diet therapy. Its main effects include: strengthening the spleen and stopping diarrhea: the gorgon fruit can enhance the spleen and stomach function, promote digestion, and has a good improvement effect on symptoms such as weak spleen, indigestion, loose stools, etc. It can promote the spleen's function and strengthen the digestive function of the spleen and stomach, thereby alleviating the above symptoms.

[0064] Dehumidification and leucorrhea prevention: Gorgon fruit has the effect of removing moisture from the body, and has a certain auxiliary therapeutic effect on abnormal leucorrhea caused by excessive moisture in women. In addition, it can also improve the symptoms of other gynecological diseases caused by excessive moisture.

[0065] Strengthen the kidney and consolidate the essence: Gorgon fruit has a significant effect on the symptoms of spermatorrhea, spermatorrhea, frequent urination, etc. caused by kidney deficiency. It can strengthen the kidney and consolidate the essence, prevent the loss of kidney essence, and is especially beneficial for male patients with kidney deficiency.

[0066] Nutritional supplement: Gorgon fruit is rich in starch, protein, fat, carbohydrates, and a variety of vitamins and minerals, such as calcium, phosphorus, iron, etc. These nutrients can provide the human body with sufficient energy and the necessary nutrients, and help maintain good health.

[0067] The effects of the black dates in the present invention mainly include: nourishing blood and nourishing skin: black dates are rich in iron and vitamin C, which help promote the synthesis of hemoglobin and increase the oxygen content of blood, thereby achieving the purpose of nourishing blood. At the same time, vitamin C can also promote the synthesis of collagen, which helps to maintain the elasticity and luster of the skin.

[0068] Lubricating the intestines and facilitating bowel movements: Black dates contain high levels of dietary fiber, which can promote intestinal peristalsis, increase stool volume, and soften stool, thereby playing a laxative role. For patients with constipation, eating a moderate amount of black dates can help improve constipation symptoms.

[0069] Enhance immunity: Black dates are rich in vitamins and minerals, such as vitamin A, vitamin C, calcium, phosphorus, etc. These ingredients help to enhance the body's immune function, improve the body's resistance, and prevent the occurrence of diseases.

[0070] Calming down the nerves and helping you sleep: Black dates contain certain triterpenoid compounds, which have a calming and soothing effect, helping to relieve tension and improve sleep quality. They have a certain effect on improving sleep problems such as insomnia, dreaminess, and easy awakening.

[0071] In addition, black dates also have many functions such as lowering cholesterol and preventing anemia.

[0072] Pomegranate peel is the dried peel of Punica granatum L., a plant of the Punicaceae family. Pomegranate peel is a traditional Chinese medicine in my country and has the effects of treating diarrhea, dysentery, infectious inflammation, etc.

[0073] Studies have shown that ingredients such as punicalagin, ellagic acid and gallic acid in pomegranate peel can inhibit the activity of α-glucosidase, suggesting that it has anti-diabetic effects. Most studies on pomegranate peel focus on crude extracts and single compounds, and the key component of the new active substance pomegranate peel-derived extracellular nanovesicles (PPENs) in pomegranate peel is the anti-diabetic activity.

[0074] Experimental methods: Figure 1 - Figure 4 Extraction and identification of PPENs

[0075] Extracellular vesicles were extracted from pomegranate peel by ultracentrifugation and sucrose density gradient centrifugation. The results of density gradient centrifugation are shown in Figure 1 A.

[0076] The band between 30% and 45% sucrose gradient was selected as PPENs. From the transmission electron microscopy (TEM) results, it can be seen that PPENs are typical "tray-shaped" and have a membrane structure. Figure 1 B.

[0077] The results of the nanoparticle size analyzer (NTA) test showed that the average particle size of PPENs was (188.7±8.2) nm. Figure 1 C, PDI is 0.22±0.03, less than 0.3, ξ potential is -13.5mV.

[0078] Inhibitory activity of PPENs on α-glucosidase

[0079] α-Glucosidase is a carbohydrate hydrolase secreted by the intestinal epithelium, which hydrolyzes starch and carbohydrates into glucose and monomeric sugars in the human small intestine to aid digestion. Inhibition of α-glucosidase can hinder the digestion of carbohydrates and their absorption in the small intestine, leading to reduced insulin demand. α-glucosidase inhibitors have been shown to be an effective strategy for the treatment of type 2 diabetes. PPENs have good α-glucosidase inhibitory activity with an IC50 of (35.3±1.1) μg·mL-1, which is better than the positive drug acarbose with an IC50 of (251.6±12.3) μg·mL-1.

[0080] Effects of PPENs on glucose absorption in insulin-resistant HepG2 cells

[0081] Type 2 diabetes is caused by insulin resistance, which accounts for 90% of diabetes cases. In the IR-HepG2 cell model established in this experiment, PPENs significantly increased the sugar absorption of IR cells at a mass concentration of 100 μg·mL-1, and the effect was significantly better than metformin. Figure 2 In the preliminary test, each group of drugs had no obvious cytotoxicity.

[0082] Establishment of HepG2 cell model of insulin resistance

[0083] HepG2 cells in the logarithmic growth phase were digested and cultured at 1×10 4 The cells were added to a 96-well plate at a density of 100 / well and cultured for 24 hours. The supernatant culture medium was aspirated, and the control group was added with high-glucose culture medium without insulin. The model group and the drug-treated group were added with serum-free high-glucose culture medium containing 10 μmol·L-1 insulin. After culture for 48 hours, the cells were washed twice with PBS and replaced with serum-free high-glucose culture medium. After culture for 24 hours, the glucose content in the culture medium was measured.

[0088] PPENs microRNA (miRNA) composition

[0089] miRNA is a classic class of highly conserved single-stranded RNA molecules, 18-3 nt in length, that regulate a variety of cellular processes during development and disease. miRNA binds to target mRNA3800 based on sequence complementarity, leading to transcript degradation or translation inhibition. Related evidence has shown that plant-derived miRNAs can target human transcripts and achieve cross-species regulation. A total of 293 miRNAs were aligned from PPENs, with sequence lengths mainly ranging from 18 to 23 nt. Human genes were used as target genes for prediction and KEGG annotation, and a bar graph was drawn for KEGG pathways with FDR < 0.03, see. Figure 3 . The results showed that the miRNAs in PPENs mainly target human immune-related processes and diseases. Inflammatory factors can interfere with the conduction of insulin-related signaling pathways and induce or aggravate insulin resistance. Studies have shown that plant-derived ENs can downregulate the expression of pro-inflammatory factors TNF-α, IL-1β, and IL-6, and promote the production of anti-inflammatory factors IL-10, thereby inhibiting the occurrence and development of inflammatory diseases.

[0090] Ultra-high performance liquid chromatography-time-of-flight mass spectrometry (UHPLC-Q-TOF) was used to detect metabolites in the samples, and a total of 284 metabolites were identified. The identified metabolites were statistically analyzed according to their chemical classification, and the proportion of each metabolite content is shown in Figure 4 Among them, lipids and lipid analogs accounted for 51.97%. This indicates that PPENs contain abundant lipid metabolites. Combined with the abundant lipids identified by lipidomics, it indicates that lipid compounds may be the main components that exert anti-diabetic activity.

[0091] Tian Jianhua et al. found that adding yam and lotus seeds to food can significantly reduce the blood sugar level of patients with type 2 diabetes mellitus (NIDDM). Taking the experimental flour with added yam and lotus seeds as an example, compared with the control food with the same energy structure, the fasting and 2-hour postprandial blood sugar levels were significantly lower than before treatment (p<0.01); and in terms of subjective symptoms such as fatigue, polydipsia, polyuria and lowering of total blood cholesterol, the flour with added yam and lotus seeds was significantly better than the control group (p<0.05). Therefore, on the basis of reasonable intake of essential energy nutrients for the human body, adding yam and lotus seeds has certain clinical significance for controlling fatigue, polydipsia, polyuria symptoms, and lowering blood sugar and total cholesterol levels in type 2 diabetes; Wu Xiaomei et al. found that lotus seeds can be used as an ideal food for dietary treatment of diabetes. The experimental foods included steamed bread, rice, lotus seeds, water chestnuts and yam (all containing 50g of carbohydrates). Steamed bread was used as the reference standard, and its glycemic index and C-peptide index were both set at 100. The glycemic index and C-peptide index of lotus seeds were 62 and 72 respectively, which were significantly lower than other experimental foods. It can be seen that among the five experimental foods, lotus seeds have the best effect on controlling blood sugar and insulin levels in NIDDM patients, which may be closely related to the functional substances in lotus seeds; Zeng Shaoxiao found in the study of lotus seed resistant starch that the formation of resistant starch is related to the in vitro glycemic index, and samples with high resistant starch content have a lower glycemic index, which suggests that lotus seed resistant starch plays an important role in blood sugar stability due to its slow digestion characteristics.

[0092] Most of the hypoglycemic active substances reported at this stage are organic substances, but there are also literature reports that inorganic substances in lotus seeds play an important role in the hypoglycemic process. Mani et al. evaluated the hypoglycemic properties of important trace elements in Indian white lotus and lotus seed ash on diabetic rats induced by streptozotocin. Atomic absorption spectroscopy showed that lotus seeds contain a variety of trace elements such as Mn, Zn, V, and Fe, and the content is very considerable. The results of animal experiments showed that: according to the dosage of 200 mg lotus seed ash per kilogram of body weight, after oral gavage for 30 days, the weight of diabetic rats induced by streptozotocin increased, and the hypoglycemic effect was equivalent to that of methylsulfonylurea. At the same time, the islet content and total protein in the body were significantly reduced, the amount of glycosylated hemoglobin decreased, approaching the controllable range, and a series of biological parameter indicators recovered and approached normal rats. This suggests that the hypoglycemic substances in lotus seed ash may be related to trace elements, which play a direct or indirect role in insulin secretion and maintaining normal blood sugar.

[0093] After the invention has been promoted and used, after continuous use for 15 days, more than 90% of patients with mild type I and II diabetes have basically controlled their fasting blood sugar between 3.9-6.1mmol / L and their blood sugar between 4.4-7.8mmol / L two hours after a meal after abandoning drugs or insulin. Patients who have taken it for 15 days and insist on taking it once a week have no rebound of symptoms during follow-up for more than one year.

[0094] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
