Insights

Children in the UK have a significant fibre gap, with school breakfast clubs often serving low-fibre foods. Novel high-fibre bread products were found to be acceptable to children, increasing breakfast fibre content and supporting sustained energy release.

Area of Science:

  • Nutritional Science
  • Pediatric Nutrition
  • Food Science

Background:

  • UK children's average fibre intake (14.6g/day) falls short of the recommended 20g/day by the Scientific Advisory Committee on Nutrition (SACN).
  • This 'fibre gap' disproportionately affects children from lower socioeconomic backgrounds.
  • School breakfast clubs, targeting disadvantaged children, may offer low-fibre options due to misconceptions about children's food preferences.

Purpose of the Study:

  • To increase the fibre density of school breakfast provisions.
  • To improve the digestive-metabolic quality of school breakfasts.
  • To assess the acceptability of higher-fibre foods among primary school children.

Main Methods:

  • In vitro digestion analysis of four novel bread products to correlate fibre content with glucose release.
  • Introduction of 'Prograins' breads, high-fibre cereals, and fruit into primary school breakfast clubs.
  • Assessment of children's food choices and breakfast fibre content during the intervention.

Main Results:

  • Prograins breads demonstrated lower glucose peaks and more sustained release compared to standard white bread.
  • A significant number of children accepted and selected the new, higher-fibre breakfast options.
  • The average fibre content of children's breakfasts significantly increased following the intervention.

Conclusions:

  • Nutritious, fibre-rich bread products can be successfully integrated into school breakfast menus.
  • Implementing higher-fibre breakfast provisions in schools is feasible.
  • Further large-scale studies are recommended to validate these findings in real-world settings.

Glucose 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...

Introduction to Carbohydrates

Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Carbohydrate Absorption01:25

Carbohydrate Absorption

Carbohydrates are essential macronutrients that serve as the body's primary energy source. Their digestion begins in the mouth, where salivary amylase partially breaks down complex carbohydrates such as starch into smaller oligosaccharides. This mechanical and enzymatic activity prepares carbohydrates for further processing in the gastrointestinal tract.
After being swallowed, the partially digested carbohydrates mix with gastric secretions in the stomach. However, the acidic environment...

Hormones Regulating Blood Glucose01:16

Hormones 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...

Carbohydrate Digestion00:57

Carbohydrate Digestion

Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...
