Abstract

This study was designed to determine chronic effect of high sucrose low magnesium (HSLM) diet in weanling rats on plasma thyroid profile, catecholamines and activities of key hepatic glycolytic, and gluconeogenic enzymes. Compared to control diet fed group, significantly elevated levels of plasma triiodothyronine, tetraiodothyronine, catecholamines (epinephrine, norepinephrine, and dopamine) and activity of hepatic glycolytic (hexokinase and glucokinase), and gluconeogenic (glucose-6-phosphatase) enzymes were observed in high sucrose and low magnesium fed groups. However, HSLM diet had an additive effect on all these three parameters. The study thus, assumes significance as it shows that hormonal imbalance and disorders in carbohydrate metabolism at an early stage of development can be due to dietary modification or due to deficiency of key element magnesium.
