This study examined the effect of non-encapsulated and
microencapsulated green tea extract in rats fed a high fructose
diet. Feeding high fructose for 8 weeks induced the development
of several features of MetS. First, in rats fed a high fructose
diet, serum TG, TC, and uric acid levels increased compared
to that in those given normal control diet. These data are in
agreement with several previous reports [32-34]. Bantle et al.
[35] suggested that the effect of dietary fructose on blood TG
is greater in the postprandial state than in the fasting state. In
our study, postprandial blood TG increased > 100% in rats fed
a high fructose diet compared to rats fed normal control diet.
Hypertriglyceridemia due to high fructose intake has been attributed
to an overproduction of lipid in the liver. The enhanced hepatic
TG was related to overproduction of TG and decreased TG
clearance [36]. In addition, the increased intake of fructose has
been reported to enhance oxidative damage in rats [37]. In the
present study, the high fructose diet might have increased the
level of oxidative stress by decreasing catalase activities in the
liver and kidney. Second, high fructose diet increased blood TC
