Guar Gum

Guar gum is the ground endosperm of the guar plant seeds (Cyamopsis tetragonalobus). It is estimated that commercial food-grade guar gum typically contains around 80% guaran, 5-6% crude protein, 8-15% moisture, 2.5% crude fiber, 0.5-0.8% ash, and small quantities of lipids consisting primarily of the fatty acids of plants. Guar gum is partly fermented by the intestinal microflora into short-chain fatty acids (SCFAs) during its transit through the large intestine. The rate of hydrolysis in humans is unclear, but guar gum's fermentation is likely to contribute to the production of SCFAs (Mortensen et al., 2017). Guar gum is chiefly used as a thickener and stabilizer in foods. It is a viscous fiber that slows gastric emptying and peristalsis, thus enhancing the gastrointestinal tract's anorexigenic and homeostatic signaling. A significant decrease in the formation of adiposity has been induced by preloading guar gum. The ingestion of guar gum causes an inhibitory effect on food intake, but over time this effect is lost (Hadri et al., 2015). Research shows that guar gum enhances satiety and diminishes the number of calories consumed during the day through snacking (Rao et al., 2015). Daily ingestion of 15 g of guar gum can result in significant weight loss in women (Tuomilehto et al., 1980).

The intake of 15 grams of guar gum results in lower overall serum cholesterol and low-density lipoprotein (LDL) cholesterol levels (Lalor et al., 1900). Guar gum consumption in mildly hypercholesterolemic insulin-dependent diabetic patients can improve glucose control and reduce serum LDL-cholesterol levels (Vuorinen-Markkola, Sinisalo, & Koivisto, 1992). For older female adults at risk of drops in postprandial blood pressure, guar gum consumption before a meal may be a beneficial therapy, according to a study by Jang, Hwang, and Kim (2015). The consumption of partially hydrolyzed guar gum in individuals with irritable bowel syndrome (IBS) can improve symptoms by reducing bloating and increasing stool frequency (Russo et al., 2015).
