Filter by:The obesities were aimed at the effect of whole wheat (WWB), buckwheat (BWB), and cornbread (CB) on blood glucose by comparing the glycemic index values with reference bread (RB). Overall, WWB consumption had a positive effect on blood glucose in individuals with obesity, while BWB consumption caused an increase in blood glucose levels.
In the last decades, the consumption of energy-dense diets, primarily consisting of highly digestible starchy foods like bread, along with a global increase in obesity rates and a sedentary lifestyle, has emerged as the main contributors to the development of non-communicable diseases such as cardiovascular diseases (CVD) and diabetes type 2. Therefore, there is a need to reduce the starch digestibility of bakery products, and in turn their glycemic index, with a specific emphasis on wheat bread. Several strategies have been used to decrease the glycemic index and insulin response of bread; however, most of these techniques have a detrimental effect on the texture, volume, taste, and color of bread, limiting the consumer's acceptability. Preservation of the native microstructure (cell wall integrity) and employing processing techniques to create a macrostructure (protein network and food matrix) can be used to influence the product structure and therefore how the product is chewed (oral processing), and how these factors can affect carbohydrate digestion and glycemic response. The aim of this study was to examine the effect of different textural characteristics of bread on oral processing in relation to the glycemic and insulin response of the three breads. In the present study, a total of 16 healthy volunteers will be recruited, and if eligible (they need to meet the inclusion and exclusion criteria), they will attend an oral processing test on three breads, a test to measure the glycemic index (ISO) and insulin response. The bread sample composition will be as follows: Bread A is made with 95% durum wheat fine semolina (< 400 micrometer) + 5% gluten+ 1.2% yeast + 1% salt + 59% water Bread B is made with 80% durum wheat fine semolina (< 400 micrometer) + 20% gluten+ 1.2% yeast + 1% salt + 59 % water Bread C is made with 80% durum wheat coarse semolina (> 500 micrometer) + 20% gluten+ 1.2% yeast + 1% salt + 59 % water.
The objective of the study is to evaluate the glycemic index and glycemic load of 4 chocolate milk drinks.
This study choosed good health, aged 18 ~ 25, physical standard, the glucose tolerance test normal adults 12, oral glucose (reference) respectively in different periods, the valley of fiber powder upgrade formula, perfect meals, by extraction shu cereal bars, light appearance suits (by extraction shu compound dietary fiber powder, feeding combination 1:1) and 17 extraction enzyme 6 kinds of food, Venous blood was collected 15, 30, 45, 60, 90 and 120 min before and after oral administration respectively. Blood was collected for 7 times with 2mL each. The plasma is then separated to determine glucose levels. Blood glucose was measured within 3 h. With glucose as the reference, food glycemic index (GI) was calculated using the internationally used Wolever method. Time was taken as abscissa and blood glucose value at each time point was taken as ordinate to prepare the blood glucose response curve of each food tested after eating. The elevated glycemic area (AUC) under the glycemic curve was calculated geometrically, and the food GI and glycemic load (GL) values were calculated according to the following formula: GI value = (2 h post-meal blood glucose AUC of the tested food / 2 h post-meal glucose glucose AUC of the same amount of carbohydrate)×100, GL=GI*M(100g of the actual available carbohydrate of a food)/100.
Within the SWEET project (EU funded), in Work Package 2 there are two phases, this study refers to Phase 1 of the SWEET WP2 project, which will be a coordinated trial across 3 intervention centres, University of Navarra (UNAV), University of Liverpool (ULIV) and University of Copenhagen (UCPH). It will involve an acute intervention in 120 individuals to explore initial acceptance, safety and post-prandial effects of 3 S&SE blends delivered in beverage format. The main endpoints of the SWEET WP2 Phase 1 study will be glycaemic and lipaemic responses; eating behavior (subjective appetite, food preference, cravings, reward), and health effects (rebound hunger, G.I. side effects and metabolic effects). This phase will be exploratory and will not involve any specific primary hypotheses.
Compare the effects of whole orange, orange juice alone, and orange juice with added orange pomace fiber, and whole apple, apple juice alone, and apple juice with added apple pomace fiber, on 2h glycemic response.
The effect of content of barley beta-glucans in bread on postprandial blood sugar will be measured with open-label crossover study. Study will be conducted in Slovenia on 10-12 adult subjects who will test three barley beta-glucan containing bread formulations (food) in comparison with a reference white bread. Objective of the study is to investigate the influence of the content of barley beta-glucan in bread on glycaemic index (incremental area under the curve (IAUC) for the blood glucose response curve for barley beta-glucan containing breads in comparison to reference white bread.
This study is an open-label with a randomized, cross-over design using standard GI methodology.
The results of our in vitro studies strengthen the hypothesis that the contribution of salivary alpha-amylase to starch digestion has been underrated and that this enzyme can play an important role in this process. As a result, its inhibition could constitute an opportunity to reduce the glycemic response elicited by starch-rich foods. The main goal of this study is to verify whether inhibiting salivary alpha-amylase upon the consumption of starchy foods, can have an impact on the postprandial glycemic response, and/or satiety.
The study is open-label with a randomized, cross-over design using standard Gl methodology.
