Effect of inclusion of cashew globulin (Anacardium occidentale) to a casein diet on lipid parameters in rats.
The effect of inclusion of cashew globulin to a casein diet on lipid metabolism was studied in rats fed diets with two levels of cashew globulin meal. Inclusion of cashew globulin to a casein diet produced lower levels of total cholesterol, triacylglycerol and phospholipids in the serum and tissues and lower levels of serum lipoprotein cholesterol. There was decreased cholesterogenesis in the liver as evidenced by decreased activity of HMG CoA reductase and decreased release of lipoproteins into circulation. Rats fed cashew globulin along with casein also showed higher activity of LPL in the heart and adipose tissue and higher activity of LCAT. Increased hepatic diversion of cholesterol to bile acid synthesis and increased excretion of bile acids and sterols were also observed in these groups. Activity of glucose-6-phosphate dehydrogenase and malic enzyme was decreased in rats fed cashew globulin along with casein. This study demonstrates that cashew globulins included in the diet of rats are able to alter lipid metabolism which results in lower levels of lipid parameters in the serum and tissues.
