雄性SD大鼠给予高脂肪膳食、高胆固醇膳食、高糖膳食、高蛋白膳食15天后，测定血糖和脂质含量，结果显示：高脂肪膳食引起脂肪肝，在血清和肝脏甘油三酯（TG）增加的同时，使血清总胆固醇（TC）、高密度脂蛋白胆固醇（HDL－C）、低密度脂蛋白胆固醇（LDL－C）和血糖都显著增高，尤其是血糖增加最明显。高胆固醇膳食血和肝脏中的TC、TG、HDL－C、LDL－C和血糖均明显增加，尤以血和肝脏中的胆固醇和血LDL－C浓度增加为主。高糖膳食未见血糖浓度增加，血和肝脏中的TG、TC、LDL－C也明显增加，肝脏脂肪化。高蛋白膳食能引起血清TG浓度显著降低，其它各项指标虽有降低，但光显著差异。
Male SD rats were given high-fat diet, high-cholesterol diet, high-sugar diet, high-protein diet for 15 days after the determination of blood glucose and lipid content, the results showed that: high-fat diet caused fatty liver in serum and liver triglyceride (TG) (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and blood sugar were significantly increased, especially the most obvious increase of blood sugar. High cholesterol dietary blood and liver TC, TG, HDL-C, LDL-C and blood glucose were significantly increased, especially in blood and liver cholesterol and blood LDL-C concentration increases. High blood sugar diet did not increase blood glucose levels, blood and liver TG, TC, LDL-C also significantly increased, fatty liver. High-protein diet can cause serum TG concentration was significantly reduced, although other indicators have decreased, but the light was significantly different.
