Eggs rich in α-linolenate (LNA, 18: 3, ω3) were produced by supplementing the feed of laying hens (Dekalb XL-L) with 2% linseed oil. Four healthy volunteer students (19-21 years) with low ω3/ω6 ratios of fatty acids (less than 0.11) in plasma were selected from 94 female students. They had a low fish consumption, but usually ate eggs every day. During the experimental period, they added two eggs rich in LNA (LNA-Egg) per day to their ordinary diet for 3 weeks. Then plasma cholesterol (CHL), triaclyglycerol (TG) and fatty acid composition were compared with those during the basal period. Plasma levels of CHL and TG in the LNA-Egg-fed students tended to decrease in comparison with their basal values. Analysis of plasma fatty acid composition showed that the percentage of docosahexaenoic acid (22: 6, ω3) was significantly increased, and that those of LNA and icosapentaenoic acid (20: 5, ω3) tended to increase after dietary supplementation with LNA-Eggs. LNA-Egg supplementation of the diet for 3 weeks reduced the level of plasma arachidonic acid (20: 4, ω6), but no significant effect was observed on the level of plasma linoleic acid (18: 2, ω6). Consequently, the ratio of ω3 to ω6 fatty acids in plasma was elevated significantly from 0.07±0.03 to 0.16±0.08 (p<0.01) after intake of the LNA-Eggs for 3 weeks. We conclude that LNA-Eggs may be a useful dietary component for increasing the ratio of ω3 to ω6 fatty acids in subjects with a low fish intake.
