This study aimed to investigate the effects of Green tea wealthy with catechin and inulin to improve diabetics' rats. The results showed that the green tea enriches with catechin and inulin counteracted improved the BWG and FER in diabetics' rat groups. It could be noticed that the significant results for BWG and FER were recorded for rats of group 8 which treated by a high dose of green tea enriched with catechin and inulin. Also, this treated group of rats had the lowest total cholesterol, triglycerides LDL cholesterol and serum VLDL cholesterol also. However, HDL cholesterol was the minimum in animals of this group. The Kidney and liver function in the diabetics' different rat groups fed on basal diet and taken orally 1.5ml/kg/ body weight/day of green tea enriched with catechin and inulin were improved. On the other hand,green tea, it was found that catechin and inulin decreased the serum glucose in the different diabetics rat groups and improved their atherogenic index (A.I) and cardiovascular disease risk (CVD risk). The observed improvement in diabetics' different rat groups taking the green tea and catechin may be due to the presence of natural antioxidant in catechin which scavenging the free radical in the blood. Also, inulin is used as dietary fiber in functional foods which loss the gain body weight. It could be recommended from the above results that orally taking 1.5ml/kg/ body weight/day from green tea enriched with catechin and inulin (extract from boiling 20 g of green tea leaves/liter of water with 0.5 mg catechin plus 18 g of inulin) improved diabetics' rats.
