American ginseng (Panax quinquefolius L.) attenuates postprandial glycemia in a time-dependent but not dose-dependent manner in healthy individualsV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, Toronto
Am J Clin Nutr 73:753-8. 2001..Whether this effect can be replicated with doses <3 g and administration times closer to the oral glucose challenge is unclear...
American ginseng (Panax quinquefolius L) reduces postprandial glycemia in nondiabetic subjects and subjects with type 2 diabetes mellitusV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, St Michael s Hospital, Ontario, Canada
Arch Intern Med 160:1009-13. 2000..We therefore undertook a preliminary short-term clinical study to assess whether American ginseng (Panax quinquefolius L) affects postprandial glycemia in humans...
American ginseng improves glycemia in individuals with normal glucose tolerance: effect of dose and time escalationV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto and Clinical Nutrition and Risk Factor Modification Centre, St Michael s Hospital, Ontario, Canada
J Am Coll Nutr 19:738-44. 2000..in nondiabetic individuals to achieve further improvements in glucose tolerance seen previously when 3 g of AG was taken 40 minutes before a 25 g glucose challenge...
Konjac-mannan (glucomannan) improves glycemia and other associated risk factors for coronary heart disease in type 2 diabetes. A randomized controlled metabolic trialV Vuksan
Department of Nutritional Sciences, St Michael s Hospital, Faculty of Medicine, University of Toronto, Ontario, Canada
Diabetes Care 22:913-9. 1999..To examine whether Konjac-mannan (KJM) fiber improves metabolic control as measured by glycemia, lipidemia, and blood pressure in high-risk type 2 diabetic patients...
Similar postprandial glycemic reductions with escalation of dose and administration time of American ginseng in type 2 diabetesV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, Ontario, Canada
Diabetes Care 23:1221-6. 2000..We previously demonstrated that 3 g American ginseng (AG) reduced postprandial glycemia (PPG) in type 2 diabetic individuals. We investigated whether further reductions can be achieved with escalation of dose and time of AG administration...
Konjac-Mannan and American ginsing: emerging alternative therapies for type 2 diabetes mellitusV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, and Clinical Nutrition and Risk Factor Modification Centre, St Michael s Hospital, Ontario, Canada
J Am Coll Nutr 20:370S-380S; discussion 381S-383S. 2001..A determination of the active ingredients in AG, and the rheology-biology relationship of KJM are also warranted...
Variable effects of American ginseng: a batch of American ginseng (Panax quinquefolius L.) with a depressed ginsenoside profile does not affect postprandial glycemiaJ L Sievenpiper
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada
Eur J Clin Nutr 57:243-8. 2003..These data suggest that the ginsenoside profile of AG might play a role in its hypoglycemic effects. The involvement of other components cannot, however, be precluded...
Beneficial effects of viscous dietary fiber from Konjac-mannan in subjects with the insulin resistance syndrome: results of a controlled metabolic trialV Vuksan
Department of Nutritional Sciences, St Michael s Hospital, University of Toronto, Canada
Diabetes Care 23:9-14. 2000..To test this hypothesis, we investigated the effect of supplementing a high-carbohydrate diet with fiber from Konjac-mannan (KJM) on metabolic control in subjects with the insulin resistance syndrome...
Simple skinfold-thickness measurements complement conventional anthropometric assessments in predicting glucose toleranceJ L Sievenpiper
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto and the Clinical Nutrition and Risk Factor Modification Centre, and the Division of Metabolism and Endocrinology, St Michael's Hospital, Toronto, ON, Canada
Am J Clin Nutr 73:567-73. 2001..59, P < 0.001) and the insulin sensitivity index (partial R(2) = 0.49, P < 0.001). CONCLUSION: Skinfold-thickness measurements may complement other established measurements for predicting abnormal glucose and insulin regulation...
A novel source of wheat fiber and protein: effects on fecal bulk and serum lipidsV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, St Michael s Hospital, Ontario, Canada
Am J Clin Nutr 69:226-30. 1999..Wheat fiber is a laxative and wheat protein may affect blood lipids...
Viscous and nonviscous fibres, nonabsorbable and low glycaemic index carbohydrates, blood lipids and coronary heart diseaseD J Jenkins

Curr Opin Lipidol 11:49-56. 2000..In larger cohort studies, low glycaemic index foods or low glycaemic load diets have been associated with higher HDL-cholesterol levels and reduced incidence of diabetes and cardiovascular disease...
Viscosity of fiber preloads affects food intake in adolescentsV Vuksan
Department of Nutritional Sciences, Faculty of Medicine, University of Toronto, Toronto, Ontario, Canada
Nutr Metab Cardiovasc Dis 19:498-503. 2009....
