Results are means ± SD (n = 2). An SD of 0.0 implies an SD of < 0.05. Mean values within the same dietary trial bearing different superscript letters are significantly different (P < 0.05). ¹Totals include 15:0, 20:0, 22:0, and 24:0. ²Totals include 16:1n−9, 18:1n−11, 20:1n−7, 22:1 isomers, and 24:1. ³Totals include 18:3n−6, 20:2n−6, and 22:4n−6. ⁴Totals include 20:3n−3 and 22:3n−3
