Abstract
Description
[Technical field]
[0001] The present invention generally relates to the use of a composition comprising a mulberry leaf extract, a fiber source, and a source of unsaturated fatty acids to reduce postprandial glycemic (PPG) response. More specifically, the present invention relates to the use of such a composition administered with a meal to reduce postprandial glycemic (PPG) response. The present invention also relates to a composition comprising a mulberry leaf extract, a fiber source, and a source of unsaturated fatty acids to be administered with a meal for use in treating and / or preventing disorders related to postprandial glycemia and / or postprandial insulin in a subject. [Background technology]
[0002] Diabetes is a metabolic condition characterized primarily by high blood glucose levels resulting from the body's inability to produce or use insulin. Hyperglycemia can lead to many clinical complications, including blindness, limb amputation, heart attack, or stroke.
[0003] The most common types of diabetes are insulin-dependent diabetes mellitus (type 1 diabetes, T1D) and non-insulin-dependent diabetes mellitus (type 2 diabetes, T2D). The most common type is type 2 diabetes (T2D), which is increasing mainly due to the increasing prevalence of obesity.
[0004] Furthermore, the pre-diabetic state, defined as having blood glucose higher than normal but not high enough to be diagnosed with diabetes, is associated with a large increase in the diabetic population.
[0005] Insulin resistance (low insulin sensitivity) also occurs in pregnant subjects. This insulin resistance is due to hormonal changes that act to support the transfer of nutrients from the pregnant subject to the fetus. As mentioned above, in response to insulin resistance, the pancreas may compensate by secreting more insulin. These subjects are considered to have impaired glucose tolerance (hereinafter IGT). Eventually, the pancreas may not be able to keep up with the body's increased demand for insulin, leading to type 2 diabetes. Any degree of glucose intolerance with onset or first recognition during pregnancy is called gestational diabetes mellitus (GDM).
[0006] The pathophysiology of the development of type 2 diabetes is complex and multifactorial. Obesity, sedentary lifestyle, and / or aging can lead to insulin resistance and increased circulating insulin concentrations over time. At some point, impaired glycemic control begins to appear, leading to impaired glucose tolerance (IGT) or impaired fasting glucose (IFG), which can eventually lead to type 2 diabetes. Thus, IGT and IFG refer to intermediate metabolic states between normal glucose homeostasis and diabetes.
[0007] A further test, an oral glucose tolerance test (OGTT), can be performed to assess whether the patient is diabetic or has IGT. The OGTT involves a glucose drink containing 75 g of glucose. The patient's blood glucose level is measured 1 and 2 hours after administration of the drink.
[0008] Glucose is an essential nutrient for the human body, and its circulating blood concentration must be carefully maintained constant to provide adequate amounts to peripheral tissues. The liver plays a central role in glucose homeostasis by balancing the uptake and storage of glucose via glycogen synthesis with its release by glycogenolysis and gluconeogenesis. Impaired glucose homeostasis is a typical feature of type 2 diabetes. Type 2 diabetic patients show increased hepatic glucose production (HGP). This increase has been identified as the main cause of fasting hyperglycemia, and is accompanied by a reduced plasma glucose clearance (Gastaldelli A, et al., Diabetes 2000;49:1367-1373), as well as a 25-45% reduction in glycogen synthesis compared to nondiabetic subjects (Roden M, et al., Best Pract Res Clin Endocrinol Metab. 2003;17:365-83).
[0009] Optimal glycemic control is the cornerstone of diabetes management. Both fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) levels correlate with risk of complications and are related to measurements of glycated hemoglobin (A1C). A1C levels above 7.0% are associated with a significantly increased risk of both microvascular and cardiovascular (CV) complications. PPG is an important component of hyperglycemia overall and may be a major component in patients near their A1C goals and in middle-aged and older adults.
[0010] PPG is determined by several factors, such as the total caloric content of the diet, the composition of macronutrients, and the quality of carbohydrates (e.g., glycemic index / glycemic load), all of which can be monitored and controlled. However, it is more complicated because several other factors involved in diseases such as T2D cannot be controlled and vary between individuals. These factors include gastric emptying rate, intestinal absorption rate, enteroendocrine incretin secretion by enteroendocrine cells, incretin sensitivity, insulin secretory function of pancreatic beta cells, hepatic glucose production, glucose availability, glucose uptake in all tissues (especially brain, fat, liver, muscle), insulin sensitivity, and renal glucose reabsorption.
[0011] Limiting postprandial glycemic peaks in diabetic patients is an important goal in the overall glycemic management strategy. Poor control of PPG is common in diabetes. This poor control contributes to overall hyperglycemia and is associated with poor prognosis. Therefore, therapeutic candidates that specifically target PPG are a key component to achieving and maintaining glycemic control in patients with type 1 diabetes (T1D) and type 2 diabetes (T2D) and may prevent the progression of prediabetic conditions to a diabetic state.
[0012] Several lines of evidence have demonstrated the importance of PPG and postprandial insulin (PPI) in both the management and prevention of type 2 diabetes. PPG has been shown to be the major contributor to total glucose excursion in T2D patients with HbA1c <8%, i.e., well-controlled diabetic or prediabetic patients. Postprandial hyperinsulinemia has been shown to be a marker of prediabetes and metabolic syndrome (M. Shanik et al., Diabetes Care 2008 Feb;31(Supplement 2):S262-S268.). Prediabetic conditions are rapidly increasing worldwide and are primarily associated with age and BMI. In overweight and obese populations, as well as those at risk for T2D, control of PPG and / or PPI responses appears to be important in the prevention of such diseases.
[0013] The current treatment of T2D involves several classes of drugs that can be used alone or in combination with insulin.
[0014] Alpha-glucosidase inhibitors slow down carbohydrate digestion, retard glucose absorption, and reduce postprandial blood glucose increase. Common side effects include abdominal pain, diarrhea, and flatulence. The antidiabetic drug acarbose is an alpha-glucosidase inhibitor. However, by also inhibiting alpha-amylase activity, gastrointestinal side effects, especially flatulence and diarrhea, have been reported.
[0015] Carbohydrates are an important nutrient in the human diet and the major dietary component that influences glycemia. The amount and type of carbohydrates affect both postprandial glycemia and blood insulin. Postprandial glycemia, together with associated hyperinsulinemia and lipidemia, is involved in the development of chronic metabolic diseases such as obesity, type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). A meta-analysis of 24 prospective cohort studies demonstrated a strong and significant lower risk of developing T2D in individuals consuming a low glycemic load diet.
[0016] Mulberry leaves have been used for centuries in traditional Chinese medicine as a common ingredient to treat a variety of conditions, including diabetes, atherosclerosis, and cancer, and to boost the immune system through its powerful antioxidant activity. Studies have shown that mulberry plant material contains a variety of bioactive components, including flavonoids, polyphenols, polysaccharides, and 1-deoxynojirimycin (DNJ), which has been identified as an α-glucosidase inhibitor, fagomine, or GABA.
[0017] WO 2013 / 078658 reports the effect of mulberry juice on blood glucose levels after ingestion of high glycemic index carbohydrates. EP 3145332(A1) reports the reduction of postprandial blood glucose and insulin spikes after administration of a composition containing a combination of white kidney bean extract (1,200 mg), mugwort extract (600 mg), and green coffee bean extract (400 mg) 15 minutes before a carbohydrate meal.
[0018] There is a continuing need in the food industry to further improve the nutritional solutions given to subjects with diabetes or at risk of developing type 2 diabetes.
[0019] Alternative solutions to replace the ingestion of capsules or pills to reduce post-prandial glycemic response may be attractive to consumers and increase consumer compliance. The aim of the present invention is to improve the state of the art and to provide new and advantageous nutritional solutions for improving the PPG profile in subjects, in particular in diabetic subjects or in subjects at risk of developing T2D.

The diet can be any meal, such as breakfast, lunch, or dinner.
[0078] As used herein, a "high carbohydrate diet" refers to a diet in which 40-90% Kcal of the dietary energy intake is derived from carbohydrates. In preferred embodiments, the energy intake from carbohydrates in such a diet is greater than 50%, more preferably greater than 60%, 70%, or 80%.
[0079] Glycemic index is defined as the incremental area under the glycemic response curve for a 50 g carbohydrate portion of the test meal, expressed as a percentage of the response to the same amount of carbohydrate when the same subject consumes a standard meal.
[0080] A food is considered to have a low GI if its GI value is 55 or less, a high GI if it is 70 or more, and a mid-range (medium) GI if it is 56 to 69. As used herein, a "medium-high GI mixed diet" refers to a diet that has a GI above 55, preferably 56 to 70 or more.
