Background: 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 &ldquo;healthy heart&quot; nutritional guidelines. However, the effects of cultured shrimp on serum lipoproteins of normal subjects have not yet investigated. Material and Methods: 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. Results: 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). Conclusion: 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.
