Evaluation of the possible inclusion of certain fish species in chronic kidney disease diets based on their adverse and beneficial nutrient ratios.

摘要

The adverse (P, protein, Na, K and cholesterol) and beneficial (n-3 fatty acids (eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA)) and vitamins D₃ and E) nutrients in 14 fish species were quantified, in order to evaluate their inclusion in chronic kidney disease (CKD) diets. Using AOAC methods, the following results per 100 g of fish were obtained: 50.86-227.52 mg K, 14.7-30.6 g protein and 3.83-1667.35 mg EPA+DHA. CKD patients with protein or K restrictions should avoid broadbill swordfish, black bullhead and spotted scorpionfish. However, patients may include parrot sand bass, black bullhead, broadbill swordfish, longjaw leatherjacket, oilfish, Atlantic tripletail, spotted scorpionfish and round herring in their diets based on the P/EPA+DHA ratios of these fish. Some fish species may be included in CKD diets because of their high biological value protein content - associated with cardiovascular and renal protective nutrients (EPA+DHA) - and low P, Na, K and cholesterol content; their consumption by CKD patients should be encouraged.
