Intensive farming could also be an additional factor contributing to insufficient
n-3 PUFA consumption as n-3 PUFA content in somespecies of farmed fish, as rainbow trout [26], bream [27], salmon coho, or catfish [28], are reduced compared to their wild counterparts. As a result, n-6 PUFA consumption has become progressively much higher than that of n-3 PUFA
[29], so thatWestern diets have a n-6/n-3 ratio ranging from 10/1 to 20/1 for a ratio of 1/1 in the diet of our ancestors [17, 30].
