Abstract

1 The effect of chronic saccharin (benzosulphimide) consumption on glucose homeostasis was examined in normal lean +/+ mice and genetically obese hyperglycaemic insulin-resistant ob/ob mice. 2 Consumption of a 5% (w/v) sodium saccharin solution for 7 weeks prevented the development of hyperglycaemia, improved glucose tolerance (area under curve decreased by 51%), reduced the extent of hyperinsulinaemia (by 21%), and reduced excessive weight gain (by 18%) in ob/ob mice. 3 Consumption of 5% (w/v) sodium saccharin temporarily decreased hyperphagia at the beginning of treatment, decreased hepatic glycogen content (by 47%), increased abdominal muscle glycogen content (by 82%), but did not significantly alter the hypoglycaemic response to exogenous insulin in ob/ob mice. 4 Consumption of a 1% (w/v) sodium saccharin solution did not prevent the development of hyperglycaemia in ob/ob mice. 5 Normal lean +/+ mice consuming 5% (w/v) sodium saccharin solution showed a marginal decrease (by 8%) in glycaemia, and glucose tolerance was improved (area under curve decreased by 30%) without a significant change in the insulin response to glucose or the hypoglycaemic effect of exogenous insulin. 6 The results suggest that chronic consumption of saccharin can defer the development of hyperglycaemia and improve glucose homeostasis in insulin-resistant ob/ob mice through a mechanism that is independent of insulin.
