FO, fish oil; SO soyabean oil; en%, percentage of energy; HUFA, highly unsaturated fatty acids.

^*Calculated from the Lands equation⁽⁴⁾: (20: 3n-6 + 20: 4n-6 + 22: 5n-6)/(20: 3n-6 + 20: 4n-6 + 22: 5n-6 + 20: 5n-3 + 22: 5n-3 + 22: 6n-3)×100.

^†Calculated from (n-3 HUFA × 0·32) − 3·5 based on Harris & von Schacky⁽⁶⁹⁾ and Lands⁽⁷⁰⁾.
