COMPARISON OF DIET INDUCED METABOLIC SYNDROME WITH ARTIFICIALLY INDUCED METABOLIC SYNDROME IN A RAT MODEL
Background: Metabolic syndrome is an emerging health problem. The diets rich in fats and refined carbohydrates and monosodium glutamate are considered major risk factors for this emerging epidemic. The aim of this study was to determine whether high fat high carbohydrate (HFHC) diet, Monosodium glutamate (MSG) diet or their combination is faster/more potent inducer of MS. Methods: Twenty male Sprague Dawley rats were randomly divided into four groups. Group 1 was given normal rat chow, group 2 was given HFHC diet, group 3 was given MSG in diet and group 4 was given both HFHC and MSG in their diet for 20 weeks. Body weight, blood pressure, lipid profile and glycaemic indices were determined at the end of study. Results: After 20 weeks of study, HFHC and MSG groups showed full blown Metabolic syndrome (MS) with development of obesity, hypertension, hyperglycaemia and dyslipidemia. However, group 4 which was given combination diet did not develop features of MS. Conclusion: Both HFHC and MSG containing diets when given alone are potent inducers of MS in rat model rather than their combination.
