Concentrations of n-6 fatty acids in various tissues by following a vegan or non-vegan diet (as cited in text).
| Author, Year | Plasma | Serum | Erythrocyte and Whole Blood | Platelets | Breastmilk | Adipose |
|---|---|---|---|---|---|---|
| Rosell et al., 2005 [10] | Higher concentrations of LA in VGN plasma fatty acids than in meat-eaters, but found no significant differences in AA. | - | - | - | - | - |
| Li et al., 1999 [39] | Higher concentrations of LA in VGN plasma fatty acids than in meat-eaters, but found no significant differences in AA. | - | - | VGNs had higher levels of LA in platelets, but lower levels of AA than the high meat-eaters. | - | - |
| Mann et al., 2006 [45] | Higher concentrations of LA in VGN plasma fatty acids than in meat-eaters, but found no significant differences in AA. | - | - | - | - | - |
| Pinto et al., 2017 [9] | No significant differences between plasma LA or AA in VGNs or omnivores. | - | No difference for LA or AA in blood fatty acid profiles of VGNs and meat eaters. | - | - | - |
| Sanders et al., 1978 [46] | Higher LA and AA plasma choline phospholipids in VGNs compared to omnivores. | - | Higher levels of LA in VGNs than omnivores, but no significant differences for AA in erythrocytes. LA was higher in breastfed VGN infant erythrocytes compared to omnivore breast-fed infants, and AA was not significantly different. | - | - | Higher levels of LA in VGN adipose tissue compared to omnivore adipose tissue. |
| Elorinne et al., 2016 [11] | - | Higher LA, but no significant differences of AA in VGN serum compared to non-VGN serum. | - | - | - | - |
| Agren et al., 1995 [42] | - | Higher LA, but no significant differences of AA in VGN serum compared to non-VGN serum. | Higher levels of LA in VGNs than omnivores, and higher AA in omnivores. | Higher levels of LA in VGN platelets, but no differences of AA compared to omnivores. | - | - |
| Sarter et al., 2015 [16] | - | - | No difference for LA or AA in blood fatty acid profiles of VGNs and soldiers. | - | - | - |
| Kornsteiner et al., 2008 [40] | - | - | Higher levels of LA in VGNs than omnivores, and higher AA in omnivores. | - | - | - |
| Fisher et al., 1986 [47] | - | - | - | Higher platelet LA concentration, and lower AA in both the VGN and vegetarian subgroups as compared to omnivores. | - | - |
| Sanders et al., 1992 [48] | - | - | - | - | Higher levels of LA in VGN breastmilk compared to omnivores, but there were no significant differences for AA. | - |
| Perrin et al., 2018 [12] | - | - | - | - | No significant differences for LA or AA in VGNs as compared to omnivores. LA:ALA ratio was significantly lower in VGNs than omnivores. | - |
| Miles et al., 2019 [41] | - | - | - | - | - | LA was higher in VGNs than non-vegetarians. AA was significantly lower in VGNs than non-vegetarians. |
