Abstract
This study was conducted to investigate the effect of dietary zinc on macro mineral contents of high fat diet-induced obese rats. The obese group was divided into three groups by zinc levels of diet, such as low (50% requirement), adequate (100%) and high (200%) levels of dietary zinc. The calcium, magnesium, sodium and potassium contents in serum and organs were measured by ICP. There were no significant differences in the food intake, weight gain and feed efficiency ratio among the different dietary zinc levels. Also, the liver, kidney and spleen weight did not show the significant differences among each level of dietary zinc. However, serum sodium and potassium concentrations in the low zinc diet group were significantly higher than in the other diet groups. In high zinc diet group, the calcium contents of liver was significantly higher than in the other diet groups, magnesium and potassium contents of liver were higher than in the low zinc diet group. The sodium contents of liver and magnesium and potassium contents of spleen were significantly lower in the low zinc diet group than in the other diet groups. In conclusion, the macro mineral contents of serum, liver and spleen in obese rats were changed by dietary zinc levels. Especially, the low zinc diet group considerably changed of macro mineral contents in organs. Therefore, it may be suggested that adequate level of dietary zinc in obese individuals should be required.
