As with other seafood, shrimp is high in calcium, iodine and protein but low in food energy. A shrimp-based meal is also a significant source of cholesterol, from 122 mg to 251 mg per 100 g of shrimp, depending on the method of preparation. Shrimp consumption, however, is considered healthy for the circulatory system because the lack of significant levels of saturated fat in shrimp means that the high cholesterol content in shrimp actually improves the ratio of LDL to HDL cholesterol and lowers triglycerides.Shrimp and other shellfish are among the most common food allergens.They are not kosher and thus are forbidden in Jewish cuisine. Shrimp are halal according to some madhāhib, and therefore permissible to most, but not all, Muslims.
