Effect of red and white grapes and their seeds extract on hyperuricemia in rats fed high fructose diet

ABSTRACT

Hyperuricemia appear to be rapidly increasing worldwide and frequently cause symptoms of metabolic syndrome. Elevated uric acid is influenced by dietary and lifestyle factors, and dietary modification is effective in reducing hyperuricemia. So that, the present study was planned to evaluate the effects of red grapes [5%], white grapes [5%], red grapes seed extract [2.5%], white grapes seed extract [2.5%] in hyperuricemic rats fed high fructose diet [60%] for four weeks. The results indicated that, red grapes, white grapes and both seeds extract were significantly decrease [P<0.05] serum urea, uric acid and creatinine in hyperuricemic rats as compared to the control group [+ve]. There were no significant difference in kidney functions between both grapes pulp and their seed extract on the effect on serum urea, uric acid and creatinine. Also, all types of grapes and their seed extracts were significantly improve [P<0.05] lipid profile and liver functions .It could be concluded that, red and white grapes as well as their seed extracts improved kidney and liver functions and lipid profile. This study is promising and could help in the management of hyperuricemia and hypercholesterolemia. The data presented may offer a promising natural and safe new trend for the prevention or the delay of hyperuricemia
