* in the case of the distribution different than normal (verified using Shapiro-Wilk test—p ≤ 0.05), the Spearman’s rank correlation was applied (for the normal distribution—the Pearson correlation was applied); ** n-3 PUFA: Alpha-linolenic acid (ALA—18:3), eicosapentaenoic acid (EPA—20:5), docosahexaenoic acid (DHA—22:6); *** total n-6 PUFA calculated as a sum of linoleic acid (LA—18:2), gamma-linolenic acid (GLA—18:3) and arachidonic acid (ARA—20:4); SFA—saturated fatty acids; MUFA—monounsaturated fatty acids; PUFA—polyunsaturated fatty acids.
