a RDI = Recommended daily intake and upper limit intake values for a male adult with a bodyweight of 70 kg according to the World Health Organization (2002); b Upper limit intake according to National Health and Medical Research Council (2006); % RDI is based on a daily intake of 8 g dry weight of seaweed; RDA = recommended daily allowance. Data are means ± SD (n = 2). SD = standard deviation.
