Influence of partially hydrolyzed guar gum on constipation in women

Abstract: A partially hydrolyzed guar gum preparation (PHGG, average molecular weight: 20,000), obtained as a water-soluble dietary fiber by digestion of guar gum with beta-D-endomannanase, was administered as a beverage (11 g a day, bid) to 15 constipated women for 3 weeks. Defecating frequency, pH, weight, moisture, and bacterial flora of the feces were investigated and compared with the control periods. Average total dietary fiber taken from food was 9.7 +/- 0.1 g/day during the experiment. PHGG caused an increase in the defecating frequency from 0.46 +/- 0.05 (frequency/day, M +/- SE) to 0.63 +/- 0.05. Fecal moisture significantly increased from 69.1% in the control period to 73.8% by ingestion of PHGG. Fecal moisture content also increased consistent with lowering the pH of feces (r = -0.478). The frequency of Lactobacillus spp. occurrence in feces significantly increased (p < 0.05) compared with the control period. These results clearly indicate that PHGG softens and improves the output of feces.

Placebo-controlled trial of the effects of guar gum and metformin on fasting blood glucose and serum lipids in obese, type 2 diabetic patients.

Abstract: Nineteen obese patients with Type 2 diabetes mellitus were treated for periods of 3 months with placebo, guar gum (5 g three times daily) and metformin (500 mg three times daily) in a randomized double-blind, double-placebo, cross-over study. Both active agents decreased fasting blood glucose from 11.4 +/- 3.7 mmol l-1 (mean +/- SD) to 8.6 +/- 2.8 mmol l-1 on metformin (p less than 0.001) and to 9.5 +/- 3.9 mmol l-1 on guar gum (p less than 0.01). Metformin significantly reduced the very low density lipoprotein (VLDL) cholesterol concentration from 0.62 (+0.73, -0.34) mmol l-1 (geometric mean (+SD, -SD)) to 0.43 (+0.58, -0.25) mmol l-1, (p less than 0.02), but unless hyperlipidaemia was present there were no changes in other serum lipid or lipoprotein levels. In patients with serum cholesterol greater than 6.5 mmol l-1 decreases in serum triglycerides from 3.29 (+3.27, -1.64) to 2.46 (+2.55, -1.25) mmol l-1 (p less than 0.02) occurred with metformin. In these patients guar gum produced a reduction in serum cholesterol (from 7.70 +/- 0.90 to 6.41 +/- 1.11 mmol l-1, p less than 0.01) due to an effect on low density lipoproteins. These differential effects may be important in planning therapy when hyperlipidaemia accompanies Type 2 diabetes.

Liquid cleansing composition

Abstract: LIQUID CLEANSING COMPOSITION ABSTRACT Aqueous liquid cleansing compositions comprise about 8% to 50% of primary surfactant selected from anionic, cationic, zwitterionic, amphoteric and semi-polar surfactants, from about 0.1% to 6% of C6-C13 alcohol ethoxylate and from about 0.1% to 2% of a water-soluble nonionic polymeric thickening agent, preferably guar gum or derivatives thereof. The compositions have desirable foaming, product stability and skin feel characteristics.
