Health councils recommend higher fish consumption because of its associated health benefits. However, overfishing is considered the main threat to marine fisheries. To answer to the global fish demand, cultivated fish production continues to grow and may come with environmental concerns. This study aims to evaluate environmental sustainability and n-3 long chain (≥C20) polyunsaturated fatty acids (n-3 LC-PUFA) content of current fish consumption in the Netherlands. Fish consumption was assessed on two non-consecutive days by 24-hour recalls in the Dutch National Food Consumption Survey 2007–2010 (n = 3819, aged 7–69 yr).
