Abstract

Različita hrana zahtjeva različite resurse te nema jednak utjecaj na zagađenje i/ili održivost, a isto se odnosi i na različite obrsce prehrane. Dvije popularne dijete različitih karakteristika, mediteranska i ketogena, uspoređene su prema njihovoj nutritivnoj kvaliteti te je izračunat i utjecaj na okoliš, mjereći CO₂ otisak dnevnih jelovnika (n=7 za svaku dijetu) kao i CO₂ otisak izražen na 1000 kcal. Osim izrzitih razlika u makronutritivnom sastavu (ketogeni obrasac prehrane ima znatno veće udjele masti (66% vs 33% u mediteranskoj dijeti) i proteina (24% vs 19% u med. dijeti), prakticiranje ketogene dijete značajnije doprinosi emisiji stakleničkih plinova (12 kg CO₂/dan vs 6 kg CO₂/dan za mediteranske jelovnike), dok je mediteranska dijeta po svom nutritivnom sadržaju u skladu s preporukama te je znatno nižeg CO₂ otiska (oko 50% manje po danu i izraženo na 1000 kcal) te time i održivija za okoliš.

Abstract (english)

Different foods require different resources and do not have the same impact on pollution and/or sustainability, and the same applies to different types of diet. Two popular diets with different characteristics, Mediterranean and ketogenic, were compared according to their nutritional quality and the impact on the environment was calculated, measuring the CO₂ footprint of daily menus (n=7 for each diet) as well as the CO₂ footprint expressed per 1000 kcal. In addition to significant differences in the macronutrient composition (the ketogenic diet has significantly higher proportions of fat (66% vs 33% in the Mediterranean diet) and protein (24% vs 19% in the Mediterranean diet), practicing a ketogenic diet significantly contributes to the emission of greenhouse gases (12 kg CO₂/day vs 6 kg CO₂/day for Mediterranean menus), while the Mediterranean diet is in accordance with the recommendations in terms of its nutritional content and has a significantly lower CO₂ footprint (about 50% less per day and expressed per 1000 kcal) and thus more sustainable for Environment.
