The present invention generally relates to the use of a composition comprising mulberry leaf extract, a source of fiber and a source of unsaturated fatty acids to decrease postprandial glucose (PPG) response. More particularly, it relates to the use of such composition, administered with a meal, to decrease postprandial glucose (PPG) response. The invention also relates to a composition comprising a mulberry leaf extract, a source of fiber and a source of unsaturated fatty acids, administered with a meal, for use in the treatment and/or prevention of a disorder linked to postprandial glucose and/or postprandial insulin in a subject.
Diabetes is a metabolic condition characterized primarily by high blood glucose levels that results from the body's inability to make or use insulin. Hyperglycemia can lead to numerous clinical complications including blindness, limb amputations, heart attack or stroke.
The most common types of diabetes are insulin-dependent diabetes (Type-1 diabetes T1D) and non-insulin-dependent diabetes (Type-2 diabetes T2D). T2D is by far the most abundant type, and the increase in Type-2 diabetes (T2D) is mainly driven by increasing obesity rates.
Additionally, pre-diabetic conditions, defined as having a blood glucose higher than normal but not high enough to be diagnosed as diabetic, are contributing significantly to the strong rise of the diabetic population.
Insulin resistance (a low insulin sensitivity) occurs also in pregnant subjects. This is due to hormonal changes that help to ensure the transfer of nutrients from the pregnant subject to the fetus. As described above, in response to insulin resistance the pancreas may secrete more insulin to compensate. These subjects are considered as having an impaired glucose tolerance (hereinafter IGT). Eventually the pancreas may fail to keep up with the body's increased need for insulin, leading to type-2 diabetes. Any degree of glucose intolerance with onset or first recognition during pregnancy is referred to as Gestational Diabetes Mellitus (GDM).
The pathophysiology of the development of Type-2 diabetes is complex and multifactorial. Obesity, sedentary life style, and/or increased age may lead to insulin resistance and to increased circulating insulin concentrations over time. At some point, a loss of control of blood glucose begins to emerge, resulting in impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) and may ultimately result in Type-2 diabetes. Therefore, IGT and IFG refer to metabolic states intermediate between normal glucose homeostasis and diabetes.
A further test, the oral glucose tolerance test (OGTT), may be performed to assess whether the patient is diabetic or has IGT. The OGTT consists of a glucose drink containing 75 g of glucose. The patient's blood sugar level is measured at one and two hours following administration of the drink.
Glucose is an essential nutrient for the human body, so its circulating levels must be carefully maintained constant in order to supply adequate amounts to peripheral tissues. The liver plays a central role in glucose homeostasis by balancing uptake and storage of glucose via glycogenesis and its release via glycogenolysis and gluconeogenesis. An impairment of glucose homeostasis is a typical feature of Type-2 diabetes. Patients with Type-2 diabetes exhibit increased hepatic glucose production (HGP), which is identified as the main cause of fasting hyperglycemia and is associated with a reduced plasma glucose clearance (Gastaldelli A, et al., Diabetes 2000; 49:1367-1373), and also a 25-45% reduced synthesis of glycogen compared with non-diabetic subjects (Roden M, et al., Best Pract Res Clin Endocrinol Metab. 2003; 17:365-83).
Optimal glycemic control is fundamental to the management of diabetes. Both fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) levels correlate with the risk of complications and contribute to the measured glycated hemoglobin (A1C) value. A1C levels >7.0% are associated with a significantly increase risk of both microvascular and cardiovascular (CV) complications. PPG is an important component of overall hyperglycemia and may be the predominant component in patients who are closer to A1C goal and in older adults.
PPG are determined by several factors, such as the total caloric value of a meal, macronutrient composition, and carbohydrate quality (e.g., glycemic index/load), all of which may be monitored and controlled. However, multiple other factors involved in diseases such as T2D are more complex because they cannot be controlled and are variable between individuals. These include gastric emptying rate, intestinal absorption rate, enteroendocrine incretin secretion, incretin sensitivity, pancreatic beta-cell insulin secretory function, hepatic glucose production, glucose effectiveness, glucose uptake in all tissues (especially brain, adipose, liver, and muscle), insulin sensitivity, and renal glucose reabsorption.
Limiting blood glucose peaks after a meal in diabetic subjects constitutes an important target of the overall glycemic control strategy. Uncontrolled PPG is common in diabetes. It contributes to overall hyperglycemia and is associated with poor outcomes. Treatment options that specifically target PPG are, therefore, critical components to achieving and sustaining glycemic control in patients with Type-1 diabetes (T1D) and Type-2 diabetes (T2D), and might prevent pre-diabetic subjects to advance to a diagnosed diabetic condition.
Evidences are revealing the importance of PPG and post-prandial insulin (PPI) in both the management and prevention of type 2 diabetes. PPG was shown to be the main contributor to total glucose fluctuations in T2D patients with HbA1c<8%, i.e. well controlled diabetes or prediabetes patients. Postprandialhyperinsulemia has been shown to be a marker of prediabetes and metabolic syndrome (M. Shanik et al., Diabetes Care 2008 February; 31(Supplement 2): S262-S268.). Prediabetes state is rapidly increasing worldwide and is mainly associated with age and BMI. Controlling PPG and/or PPI response in the overweight and obese population, also at risk for T2D, appears to be key for preventing this disease.
Actual treatments for T2D comprise several classes of drugs, which can be used alone or in combination with insulin.
Alpha-glucosidase inhibitors slow the digestion of carbohydrates, delay glucose absorption, and reduce the increase in blood glucose after a meal. Common side effects include abdominal pain, diarrhea, and flatulence. The antidiabetic drug Acarbose is an alpha-glucosidase inhibitor. However, gastrointestinal side-effects have been reported, in particular flatulence and diarrhea, due to the fact that it also inhibits alpha-amylase activity.
Carbohydrates are important nutrient of the human diet and the main dietary component affecting glycaemia. The amount and type of carbohydrate have an effect on both postprandial glycaemia and insulinaemia. Postprandial glucose, together with related hyperinsulinemia and lipidaemia, has been implicated in the development of chronic metabolic diseases like obesity, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). A meta-analysis performed on 24 prospective cohort studies has demonstrated a strong and significant lower risk to develop T2D in persons who consume lower Glycaemic load diet.
Mulberry leaves have been used centuries in traditional Chinese medicine as a common agent to treat a variety of conditions including diabetes, atherosclerosis, cancer as well as for boosting the immune system through potent antioxidant activity. Research has shown that mulberry plant materials comprise various physiologically active components including flavonoids, polyphenols, polysaccharides, 1-deoxynojirimycin (DNJ) identified as α-glucosidase inhibitor, fagomine, GABA or the like.
WO2013/078658 reports effects of mulberry juice on blood glucose levels following consumption of high glycemic index carbohydrate. EP3145332 A1 reports reduction of post-meal glucose and insulin spikes following administration of a composition comprising a combination of white kidney bean extract (1,200 mg), white mulberry extract (600 mg) and green coffee extract (400 mg) administered 15 minutes before a carbohydrate meal.
There is a persisting need in the food industry to further improve the nutritional solutions provided to diabetic subjects or subjects at risk for developing type-2 diabetes.
Alternative solutions instead of taking capsules or pills to lower postprandial glucose response can be appealing for consumers and increase consumer compliance.
An object of the present invention is to improve the state of the art and to provide a new and advantageous nutritional solution for improving the PPG profile in a subject, particularly in a diabetic or a subject at risk for developing T2D.

The filler material, including any carbohydrate and/or fiber filler material, may represent enough of the finished product to provide the desired bulk or flow properties, but most typically represent from about 30% to about 90%, preferably from about 40% to about 85%, more preferably from about 50% to about 85%, and most preferably from about 75% to about 80%, by weight of the composition.
Carbohydrate sources suitable for use as a filler material in the compositions of the present invention, include those having a low glycemic index such as fructose and low DE maltodextrins as such ingredients do not introduce a high glycemic load into the composition. Other suitable filler material includes any dietary fiber suitable for human or animal use, including soluble and insoluble fiber, especially soluble fibres. Beneficial effects of soluble fibres on glucose response have been widely reported. Non-limiting examples of suitable soluble fibres include FOS, GOS, inulin, resistant maltodextrins, partially hydrolysed guar gum, polydextrose and combinations thereof.
Non limiting example of commercially available filler materials for use herein include Sunfiber® (Taiyo International, Inc.), which is a water-soluble dietary fiber produced by the enzymatic hydrolysis of Guar beans; Fibersol 2™ (Archer Daniels Midland Company), which is a digestion resistant maltodextrin; and polydextrose.
In an embodiment the compositions of the present invention additionally comprise a soluble fibre. In a preferred embodiment soluble fibre selected from polydextrose, a resistant maltodextrin (such as the soluble corn fiber Fibersol-2) and combinations thereof. In an embodiment the composition comprises ME and soluble fibre in a ratio fibre: ME of from about 1:1 to about 20:1, preferably from about 4:1 to about 10:1.
The composition may also comprise other filler, stabilizers, anti-caking agents, anti-oxidants or combinations thereof.
The composition may further comprise one or more additional components such as minerals; vitamins; salts; or functional additives including, for example, palatants, colorants, emulsifiers, antimicrobial or other preservatives. Non-limiting examples of suitable minerals for the compositions disclosed herein include calcium, phosphorous, potassium, sodium, iron, chloride, boron, copper, zinc, magnesium, manganese, iodine, selenium, chromium, molybdenum, fluoride and any combination thereof. Non-limiting examples of suitable vitamins for the compositions disclosed herein include water-soluble vitamins (such as thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin (vitamin B7), myo-inositol (vitamin B8) folic acid (vitamin B9), cobalamin (vitamin B12), and vitamin C) and fat-soluble vitamins (such as vitamin A, vitamin D, vitamin E, and vitamin K) including salts, esters or derivatives thereof. Vitamin C, vitamin D, vitamin B3 and/or vitamin B12 are particularly useful in the composition. In a preferred embodiment the composition is supplemented with one or more vitamin and/or mineral selected from vitamin C, vitamin B3, zinc or any combination thereof.
