|April 2, 2015
Summary
Food microstructure, involving starch, lipids, and proteins, influences how the body responds to carbohydrates. Understanding these interactions is key for designing foods with better nutritional outcomes.
Area of Science:
- Food science and nutrition
- Biochemistry of food interactions
Background:
- Starch, lipids, and proteins form complex matrices in real foods.
- Research on these ternary food systems and their interactions is limited.
- Food microstructure significantly impacts product properties, including sensory and nutritional aspects.
Purpose of the Study:
- To review microstructural principles of starch, lipid, and protein interactions in foods.
- To examine the effect of these interactions on postprandial glycemic response.
- To consider intrinsic human differences in glycemic responses.
Main Methods:
- Literature review of scientific research on food microstructure and glycemic response.
- Analysis of studies investigating starch digestion within complex food matrices.
- Consideration of individual variability in postprandial glycemic responses.
Main Results:
- Foods lacking rapidly digestible starch do not always yield the lowest glycemic response.
- Food microstructure plays a critical role in modulating starch digestion.
- Interactions between starch, lipids, and proteins significantly affect glycemic impact.
Conclusions:
- A comprehensive understanding of food microstructure is essential for nutritional food design.
- Modulating starch digestion through microstructural control is a key strategy.
- Future research should focus on the ternary system of starch, lipids, and proteins for improved food development.

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.

01:34Introduction to Carbohydrates
24.7K
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...

9.0K
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...

01:10Sugars as Energy Storage Molecules
10.4K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...

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...
