The Slovenian Nutrition Guidelines 2025: A Comparison with the Prior Slovenian FBDG, Dietary Intake, and the EAT–Lancet Diet

<b>Background</b>: The Slovenian Nutrition Guidelines 2025 (SNG2025) provide a quantified, plant-forward framework aligned with the EAT-Lancet diet, whereas previous Slovenian FBDGs were qualitative. <b>Objectives</b>: (i) To compare SNG2025 with the EAT-Lancet diet and previous Slovenian FBDGs and (ii) to assess the alignment of food intake among Slovenian adults with the SNG2025. <b>Methods</b>: The SNG2025 food group targets were mapped to the EAT-Lancet diet and previous Slovenian FBDGs and evaluated against a nationally representative intake (Si. Menu 2017/18; 18-64 years; sex-specific). Sodium intake was corroborated by 24-h urinary sodium levels (2022). <b>Results</b>: The SNG2025 introduces numeric targets across more than 16 food groups, with national adaptations (e.g., potatoes, oils and fats from foods, and dairy being optional via milk-calcium equivalents and beverage specifications). The alignment reveals very low consumption of legumes; limited consumption of vegetables, whole grains, and nuts/seeds (and fruit in men); and excess consumption of total and red/processed meat, ultra-processed foods (UPFs), free sugars/sugar-sweetened beverages, sodium, and alcohol. Biomarkers indicate a mean salt intake approximately two times the <5 g/day limit. Trans fatty acid (TFA) levels ≥ 0.5% persist in a substantial percentage of adults, predominantly from ruminant-derived TFAs. Sex-specific patterns are more adverse for men (e.g., meat, SSBs, alcohol, and sodium), whereas women have a higher intake of sweet UPFs. <b>Conclusions</b>: Slovenian diets are misaligned with the SNG2025. Priorities include increasing the intake of legumes, whole grains, vegetables, and nuts/seeds, while shifting protein sources away from red and processed meat. Additional priorities include reducing the intake of alcohol, sodium, free sugars, and UPFs through reformulation, procurement, and pricing/marketing measures, alongside routine biomarker and UPF surveillance. The SNG2025 enable monitoring and targeted implementation. Considering the limitations of the Si. Menu 2017/18 dataset, which includes food-group aggregation and limited information on food preparation, the results should be interpreted with caution with respect to the magnitude of deviations from SNG2025 targets, while the overall direction of misalignment remains robust.
