Figure 1. Examples of fish species that, when consumed, allow an individual to meet the daily recommended intake for DHA while not exceeding the US EPA RfD, prepared according to the methodology described by Tsuchiya et al.108.
Fish species are divided into three categories: species that provide levels below and above a de minimus intake ratio of 17 mg DHA for every 1 μg Hg and species that exceed this ratio while also providing for a Hg intake of less than 6 μg of Hg exposure per day. Values are based on intakes equivalent to the RfD by an individual weighing 60 kg and consuming 60 g/day.
