چکیده

BACKGROUND The intake of dietary fibre has been shown to reduce the risk of developing diabetes mellitus. The aim of this study was to compare the effects of commercial rye whole-meal bread containing whole kernels and white wheat bread on the rate of gastric emptying and postprandial glucose response in healthy subjects. METHODS Ten healthy subjects took part in a blinded crossover trial. Blood glucose level and gastric emptying rate (GER) were determined after the ingestion of 150 g white wheat bread or 150 g whole-meal rye bread on two different occasions after fasting overnight. The GER was measured using real-time ultrasonography, and was calculated as the percentage change in antral cross-sectional area 15 and 90 minutes after completing the meal. RESULTS No statistically significant difference was found between the GER values or the blood glucose levels following the two meals when evaluated with the Wilcoxon signed rank sum test. CONCLUSION The present study revealed no difference in postprandial blood glucose response or gastric emptying after the ingestion of rye whole-meal bread compared with white wheat bread.

Postprandial glucose, insulin, and incretin responses to grain products in healthy subjects.

BACKGROUND Various botanical and structural characteristics of starchy food modify the postprandial glucose and insulin responses in humans. OBJECTIVE We investigated what factors in grain products affect human glucose and insulin responses and elucidated the mediating mechanisms. DESIGN Ten men and 10 women [mean age: 28 +/- 1 y; mean body mass index (in kg/m(2)): 22.9 +/- 0.7] with normal...

The botanical integrity of wheat products influences the gastric distention and satiety in healthy subjects

BACKGROUND Maintenance of the botanical integrity of cereal kernels and the addition of acetic acid (as vinegar) in the product or meal has been shown to lower the postprandial blood glucose and insulin response and to increase satiety. However, the mechanism behind the benefits of acetic acid on blood glucose and satiety is not clear. We hypothesized that the gastric emptying rate could be inv...

Postprandial differences in the plasma metabolome of healthy Finnish subjects after intake of a sourdough fermented endosperm rye bread versus white wheat bread

BACKGROUND The mechanism behind the lowered postprandial insulin demand observed after rye bread intake compared to wheat bread is unknown. The aim of this study was to use the metabolomics approach to identify potential metabolites related to amino acid metabolism involved in this mechanism. METHODS A sourdough fermented endosperm rye bread (RB) and a standard white wheat bread (WB) as a ref...

Effect of commercial breakfast fibre cereals compared with corn flakes on postprandial blood glucose, gastric emptying and satiety in healthy subjects: a randomized blinded crossover trial

BACKGROUND Dietary fibre food intake is related to a reduced risk of developing diabetes mellitus. However, the mechanism of this effect is still not clear. The aim of this study was to evaluate the effect of commercial fibre cereals on the rate of gastric emptying, postprandial glucose response and satiety in healthy subjects. METHODS Gastric emptying rate (GER) was measured by standardized ...

Effect of solid meal on gastric emptying of, and glycemic and cardiovascular responses to, liquid glucose in older subjects.

Gastric emptying is a determinant of the postprandial glycemic and cardiovascular responses to oral carbohydrate. We evaluated the effects of a solid meal on gastric emptying and the glycemic and cardiovascular responses to oral glucose in healthy older subjects. Ten subjects aged 72.1 +/- 1.9 yr were studied. Each subject had measurements of gastric emptying, blood glucose, serum insulin, bloo...
