Polish-aMED—Polish-adapted Mediterranean diet (range of points: 0–9); bolded values are marked for the main components of PCA-derived dietary patterns with absolute loadings > |0.3| and for nine components of the Polish-aMED score; * p < 0.05, test of significance for Pearson’s correlation coefficients; NA—not applied.
