Effects of cultured shrimp (Litopenaeus vannamei) consumption on serum lipoproteins of healthy normolipidemic men

It has been suggested that moderate shrimp consumption in normolipidemic subjects will not adversely affect the overall lipoprotein profile. Hence، shrimp consumption can be included in “healthy heart«nutritional guidelines. However، the effects of cultured shrimp on serum lipoproteins of normal subjects have not yet investigated. Twenty-five healthy normolipidemic men who were workers of a shrimp farm in Bushehr province participated in a quasi-experimental study. In a crossover six weeks trial، the effect of three days per week diet (containing 300 g cultured shrimp Litopenaeus vannamei /day) on serum lipid profile was compared with a zero-marine baseline diet. After six weeks trial، serum triglyceride and HDL-cholesterol levels were not significantly changed from the baseline levels (p>0. 05). However، total cholesterol and LDL-cholesterol levels، total cholesterol to HDL-cholesterol and LDL-cholesterol to HDL-cholesterol ratios were significantly increased (p<0. 0001). Moderate cultured shrimp (Litopenaeus vannamei) consumption can increase total cholesterol and LDL-cholesterol levels in normolipidemic men. Although a diet containing native shrimp has many benefits for healthy persons، but we do not recommend cultured shrimp in a healthy heart diet for persons with dyslipidemia or cardiovascular diseases.
