• UHT ultra high temperature treatment
• Vitamins, flavors and other heat-sensitive materials are then added to the homogenized mixture.
• the resulting mixture is diluted with water as needed to achieve the desired concentrations and density ( ⁇ 1.0628 g/mL).
• the resulting nutritional emulsion is then sterilized and retort packaged into 8 oz plastic bottles.
• the selected bottles have narrow neck portions extending from 1-5 cm from the broader package body.
• compositions when packaged provide desirable features, including one or more desirable features such as physical or chemical or emulsion stability, desirable hedonics, favorable rheology or viscoelastic properties, and product performance as defined herein.
• the formulations are physically stable when packaged and stored for up to 18 months at 20 0 C and provide a blunted glycemic response with minimal or no gastrointestinal intolerance, especially when used in diabetics or other individuals in whom such a blunted glycemic response would be beneficial.
• Soluble fiber source 37% by weight of dietary fiber; ADM Company, Decatur. Illinois USA
• A1 an embodiment of the present invention is evaluated for insulin sensitivity benefits relative to separate controls (A2 and A3).
• A1 is a balanced nutritional formulation of the present invention and is compared to formulations A2 (Carb-Chromium) and A3 (carb-protein-chromium) which contain only selected components of A1 and do not contain the requisite balanced formulation required of the present invention.
• A1 is a balanced nutritional embodiment of the present invention.
• A2 is a solution comprising the functional carbohydrates and chromium picolinate of A1.
• A3 is a solution comprising the functional carbohydrates, chromium and proteins of A1. Both of the A2 and A3 solutions are prepared so the rats consume the levels of functional carbohydrates (Fibersol, Sucromalt and Glycerol) (2.83kcals/gram) and proteins (milk protein concentrate and soy protein concentrate) (3.46 kcals/gram) found in the A1 formulation.
• functional carbohydrates Fibersol, Sucromalt and Glycerol
• proteins milk protein concentrate and soy protein concentrate
• Supplement compositions do not affect fasting blood glucose concentration over the 28 day feeding period. Surprisingly, A3 and A2 increase plasma insulin compared to A1 (see Fig. 1 ; p ⁇ 0.01 on day 14 for A2 vs. A1 ). A3 significantly worsens insulin sensitivity compared to A1 (see Fig. 2). A2 supplementation magnifies the increase in glycated hemoglobin 0.9% from Day 0 to Day 28 compared to 0.2% for A1 (Fig. 3).
• the study diet increased food intake and body weight compared to control chow (p ⁇ 0.05, see Fig 7). This shows that the high fat, high sucrose study diet is preferred compared to the regular chow diet, suggesting that the rats found it highly palatable.
• rats When offered access to the A1 formulation, however, rats voluntarily consumed about 1000 kcal over the course of the study. Surprisingly, rats chose to decrease consumption of the palatable, preferred study diet to compensate for the calories they consumed as A1 formulation (p ⁇ 0.05; see Fig. 8). This suggests that the A1 formulation is surprisingly palatable and satiating, causing rats to reduce intake of a preferred solid diet.
