Effects of diets containing proteins from fish muscles or fish by-products on the circulating cholesterol concentration in rodents: a systematic review and meta-analysis.

For the subgroup fed proteins from the Salmonidae family (205 rodents included), the test for overall effect was borderline significant with P 0·05 and a mean difference of −0·24 (–0·48, 0·00) mmol/l, whereas the subgroups fed dietary proteins from the Clupeidae family (sardine and herring, a total of 150 rodents included) did not affect circulating TC concentration (P 0·44 and mean difference −0·14 (–0·50, 0·22) mmol/l).
