Effect of prickly pear (Opuntia robusta) on glucose- and lipid-metabolism in non-diabetics with hyperlipidemia--a pilot study.

Background: Besides others pectin, a soluble fibre, has been reported to be effective in lowering cholesterol levels in both animals and man with hyperlipidemia as well as being able to slow carbohydrate absorption and hence reduce the postprandial rise in blood glucose and serum insulin in patients with type-II diabetes. Aim of this pilot study was to assess the effect of prickly pear consumption on glucose- and lipid metabolism.

Design: In 24 non-diabetic, non-obese males (aged 37-55 years) suffering from primary isolated hypercholesterolemia (n = 12; group A) or combined hyperlipidemia (n = 12; group B) respectively, the influence of prickly pear pectin (Opuntia robusta)-intake on glucose- and lipid metabolism was examined.
