The treatment of poorly controlled non-insulin-dependent diabetic subjects with granulated guar gum

The effect of dietary changes on plasma lipids and lipoproteins of six Labrador retrievers

Six healthy, spayed female Labrador Retrievers (aged 5.5 to 11 years), kept under controlled conditions of exercise and housing, were fed a diet of 15 per cent fat, 24 per cent carbohydrate and 33 per cent protein for two weeks before and between each of three test diets, of differing fat to carbohydrate ratios (A 13:44, B 20:33, C 25:26 fat:carbohydrate gm per cent dry weight) given in a predetermined order for four weeks each. Fasting plasma lipoproteins and total fatty acids were measured weekly. In the fourth week of each test period post-prandial plasma lipoproteins were measured. Diets B and C increased total (P < 0.001) and LDL cholesterol (P < 0.05) whilst diet A increased HDL triglyceride (P < 0.05). Eicosapentaenoic acid (C20:5) increased on diets B and C, and oleic acid (C18:1) on diet A. Post-prandial hypertriglyceridaemia occurred on all diets. Chylomicron clearance was slower on higher fat diets. Relatively small dietary changes produced significant alterations of plasma lipids, lipoproteins and chylomicron clearance.

Endocrine and metabolic effects of guar gum in menopausal women

The effect of a gel-forming dietary fiber, guar gum (15 g/day) on blood pressure, climacteric symptoms, serum hormones (estrone, estradiol, testosterone, androstenedione, follicle-stimulating hormone and luteinizing hormone) and on blood glucose and serum lipids (cholesterol, high density lipoprotein (HDL) cholesterol and triglycerides) was studied in a double-blind, placebo-controlled, parallel-group trial involving 30 menopausal women. A total of 15 women (Group A) were treated with guar gum and 15 (Group B) with placebo, for 6 months. Patients visited the doctor at the beginning of the study and after 3 and 6 months of treatment. Climacteric symptoms decreased significantly (p < 0.001) in both groups. Serum total cholesterol decreased by 5% in the guar gum group but this was not statistically significant. No changes in serum hormone levels or in other lipid and blood glucose levels were observed in either group. Body weight and blood pressure also did not change.
