The aim of the study was to investigate the possibility of obtaining: a) reliable estimates of sea bass fillet weight and lipid/fatty acid content from simple non destructive morphometric measurements; b) estimates of healthy eating quality evaluation from effects of consumption on blood biomarkers related to atherosclerotic/thrombogenic processes. A series of parameters were measured in 708 fish. Estimates of fillet weight from b.w. and max. thickness (R-2=0.96, rsd=+/- 20.55g) and of lipid content from b.w., total length, max. thickness and condition factor (R-2=0.69, rsd=+/- 3.3g) were found to be very reliable; flesh n-3 PUFA and EPA content were also estimated from condition factor and max. girth (R-2=0.32, rsd=+/- 0.42g; R-2=0.38, rsd=+/- 0.13g). Flesh healthy eating quality was evaluated from changes in blood biomarkers (lipid profile, inflammatory markers, haemorheological profile) in dyslipidemic subjects who had eaten fillets three times a week for 10 weeks. A weekly flesh intake of 807g increased erythrocyte n-3 PUFA (P<0.05) and decreased triglycerides (P<0.008), interleukin-6 (P<0.03), interleukin-8 (P<0.04), Whole Blood Viscosity(20.400) (P<0.04) and erythrocyte filtration (P<0.008). Short term intake of sea bass therefore seemed associated with favourable biochemical changes in dyslipidemic subjects, as reflected by lower circulating levels of markers of atherosclerosis.

Abstract
The aim of the study was to investigate the possibility of obtaining: a) reliable estimates of sea bass fillet weight and lipid/fatty acid content from simple non destructive morphometric measurements; b) estimates of healthy eating quality evaluation from effects of consumption on blood biomarkers related to atherosclerotic/thrombogenic processes. A series of parameters were measured in 708 fish. Estimates of fillet weight from b.w. and max. thickness (R-2=0.96, rsd=+/- 20.55g) and of lipid content from b.w., total length, max. thickness and condition factor (R-2=0.69, rsd=+/- 3.3g) were found to be very reliable; flesh n-3 PUFA and EPA content were also estimated from condition factor and max. girth (R-2=0.32, rsd=+/- 0.42g; R-2=0.38, rsd=+/- 0.13g). Flesh healthy eating quality was evaluated from changes in blood biomarkers (lipid profile, inflammatory markers, haemorheological profile) in dyslipidemic subjects who had eaten fillets three times a week for 10 weeks. A weekly flesh intake of 807g increased erythrocyte n-3 PUFA (P<0.05) and decreased triglycerides (P<0.008), interleukin-6 (P<0.03), interleukin-8 (P<0.04), Whole Blood Viscosity(20.400) (P<0.04) and erythrocyte filtration (P<0.008). Short term intake of sea bass therefore seemed associated with favourable biochemical changes in dyslipidemic subjects, as reflected by lower circulating levels of markers of atherosclerosis.File | Dimensione | Formato | |
