Summary
Low calorie sweeteners (LCS) offer sweetness with minimal energy. Research shows each LCS may uniquely impact body weight, energy intake, and appetite due to distinct chemical structures and metabolic pathways.
Area of Science:
- Nutrition Science
- Food Science
- Metabolic Health
Background:
- Low calorie sweeteners (LCS) are widely used in food products for sweetness with reduced energy.
- Safety of individual LCS is established, but their comparative efficacy remains under-researched.
- A common assumption is that all LCS exert similar physiological and behavioral effects.
Purpose of the Study:
- To investigate the distinct efficacy of various low calorie sweeteners.
- To explore potential differences in metabolic and behavioral effects among LCS.
- To understand how unique chemical structures influence LCS effects on body weight, energy intake, and appetite.
Main Methods:
- Comparative analysis of different commercially available low calorie sweeteners.
- Examination of metabolic pathways and chemical structures of various LCS.
- Assessment of potential physiological effects mediated via sweet taste receptors, brain activation, gut hormones, and microbiota.
Main Results:
- Each LCS possesses a unique chemical structure influencing its metabolism.
- Potential for differential effects of LCS on body weight, energy intake, and appetite.
- LCS may exert varied effects on sweet taste perception, neural responses, gut hormone release, and gut microbiota composition.
Conclusions:
- Low calorie sweeteners are not uniform in their physiological and behavioral impacts.
- Understanding the unique properties of each LCS is crucial for health recommendations.
- Further research into individual LCS effects can inform personalized dietary strategies for health outcomes.

01:24The Physiology of Taste
7.0K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

27.0K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:10Sugars as Energy Storage Molecules
9.7K
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...

01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
487
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.

01:17Oral Hypoglycemic Agents: Sulfonylureas
685
Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...

01:06Oral Hypoglycemic Agents: Glinides
538
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...
