Fish fillet consumption is associated with beneficial health effects; however, little is known about whether consuming other parts of the fish such as head, backbone, skin, cut-offs, and entrails (collectively known as residuals) will provide comparable effects.
The aim of the study was to investigate if daily supplementation with cod residual protein powder would impact lipid metabolism in healthy adults.
Forty healthy, lean, physically active participants (18 women, 22 men) with normal body mass index consumed 8.1 g of proteins daily from cod residual protein powder (Cod-RP) or placebo (control) for 8 weeks.
Cod residual protein powder supplementation lowered fasting serum nonesterified fatty acids and increased serum total bile acid concentrations significantly when compared with control supplementation. Fasting serum low-density lipoprotein cholesterol and apolipoprotein (Apo) B concentrations, as well as the total cholesterol:high-density lipoprotein (HDL) cholesterol and ApoB:ApoA1 ratios, were significantly decreased within the Cod-RP group, but these changes were not different from the control group. Fasting serum concentrations of triacylglycerol, total cholesterol, HDL cholesterol, and ApoA1 were not changed within or between groups.
Eight weeks of daily supplementation with 8.1 g Cod-RP seems to be sufficient to affect lipid metabolism in healthy, lean, physically active adults.
食用鱼片对健康有益；然而，对于食用鱼的其他部分，如鱼头、鱼骨、鱼皮、边角料和内脏（统称为残余物）是否会产生类似效果，人们知之甚少。
本研究旨在调查每日补充鳕鱼残余蛋白粉是否会影响健康成年人的脂质代谢。
40名身体状况良好、体型偏瘦且经常运动的健康参与者（18名女性，22名男性），其体重指数正常，连续8周每日从鳕鱼残余蛋白粉（Cod-RP）或安慰剂（对照组）中摄入8.1克蛋白质。
与对照组相比，补充鳕鱼残余蛋白粉显著降低了空腹血清非酯化脂肪酸水平，并提高了血清总胆汁酸浓度。Cod-RP组的空腹血清低密度脂蛋白胆固醇和载脂蛋白（Apo）B浓度，以及总胆固醇：高密度脂蛋白（HDL）胆固醇和ApoB:ApoA1比值均显著降低，但这些变化与对照组并无差异。各组内和组间的空腹血清甘油三酯、总胆固醇、HDL胆固醇和ApoA1浓度均未改变。
连续8周每日补充8.1克Cod-RP似乎足以影响健康、体型偏瘦且经常运动的成年人的脂质代谢。
