RNI, recommended nutrient intake.
Non-farmed fish includes fresh, dried and fermented fish, converted to fresh weight equivalent.
Based on a female of reproductive age, with moderate physical activity level and weight of 57 kg. Fat requirements range from 25 to 35 % of total energy intake, which here is presented at the midpoint of the range (1 g fat=37 kJ).
Using quantile regression, predicted mean Zn intake was 1·18 and 0·60 mg/person per d from non-farmed and farmed sources, respectively (P<0·0001); predicted mean vitamin B12 intake was 0·87 and 0·72 µg/person per d from non-farmed and farmed sources, respectively (P<0·0001); predicted mean vitamin A intake was 11 and 6 µg retinol activity equivalents/person per d from non-farmed and farmed sources, respectively (P<0·0001).
When repeated using log-transformed outcome variable, predicted mean differences in protein intake became statistically significant (P<0·0001).
