Summary
Barley beta-glucan biscuits influenced appetite ratings in adolescents but did not significantly alter short-term food intake. This dietary fiber snack shows potential for appetite modulation but requires further study for energy control strategies.
Area of Science:
- Nutritional Science
- Adolescent Health
- Dietary Fiber Research
Background:
- Viscous dietary fiber, like barley beta-glucan, offers nutritional benefits for adolescents.
- Snacks with health benefits may aid voluntary energy intake reduction by modulating appetite.
- Dietary strategies are crucial for energy control during adolescence.
Purpose of the Study:
- To investigate the effects of barley beta-glucan-enriched biscuits on appetite and food intake in adolescents.
- To assess the potential of a novel barley beta-glucan biscuit as a tool for appetite modulation and energy control.
Main Methods:
- Twenty healthy adolescents received midmorning snacks of either barley beta-glucan-enriched (BB) or control (CB) biscuits at two preload levels (SP and LP).
- Appetite ratings were recorded before and up to 2 hours post-snack.
- Energy intake at a subsequent lunch meal was measured.
Main Results:
- Barley beta-glucan biscuits (SP-BB) decreased desire to eat and increased fullness/satiety compared to control (SP-CB).
- Females consumed significantly less energy at lunch after consuming BB snacks compared to CB snacks.
- Total energy intake correlated with preload but not biscuit type; meal composition remained consistent.
Conclusions:
- Barley beta-glucan biscuits can influence appetite sensations in adolescents.
- Despite appetite modulation, these biscuits did not significantly alter short-term food intake.
- Further research is needed to establish the role of barley beta-glucan snacks in adolescent energy balance.

01:30Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
01:24Glucagon-like Receptor Agonists
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

01:16Gastric Emptying
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

01:26Glucose Absorption Into the Small Intestine
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and 'exit' via the...
01:16Hormones Regulating Blood Glucose
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...
