Polyunsaturated	43.92 ± 1.51^a	47.42 ± 6.27^a	45.70 ± 1.89^a	48.80 ± 1.04^a
Omega-3 fatty acids	5.27 ± 0.34^a	7.88 ± 1.16^ab	7.67 ± 1.38^ab	8.62 ± 0.64^b

^§Data are (expressed as) mean percentage ± SE. Values in the same row that do not share the same superscript letter are significantly different according to analysis of variance and Duncan’s post hoc procedures (P < .05); nd = not detected. Control = AIN-76 A control diet; 4% CG = AIN-76A diet + 4% collard green powder; 4% purslane = AIN-76A diet + 4% purslane powder; 4% SPG = AIN-76A diet + 4% sweet potato green powder.

Saturated = sum of saturated fatty acids; unsaturated = sum monounsaturated fatty acids + sum polyunsaturated fatty acids); monounsaturated = sum of monounsaturated fatty acids; polyunsaturated = sum of polyunsaturated fatty acids; omega-3 fatty acids = sum of C18:3n3, C20:5n3 and C22:5n3; omega-6 fatty acids = sum of C18:2n6 and C20:4n6; omega-6/3 ratio = omega-6/omega-3 fatty acids; LA/ALA ratio = C18:2n6 (linoleic acid, LA)/C18:3n3 (α-linolenic acid, ALA); EPA + DHA = sum of C20:5n3 (eicosapentaenoic acid, EPA) and C22:6n3 (docosahexaenoic acid, DHA).

Values in rows with multiple superscript letters (e.g. ab) are not significantly different from other values containing the shared superscript letter (e.g. a or b).
