Cuisine is diet that's unique to a physical place and a human cultural group. We can taste the patterns of modern cuisine in the melding of characteristic ingredients into characteristic forms. Wheat noodles with tomato sauce points us in the direction of Italy. Fermented spiced cabbage leads us to Korean kimchi.
DISCLAIMER: These are my thoughts and experiences on what can be a deeply cultural, charged and personal topic: diet. There is a lot we don’t know, especially when it comes to what a sustainable diet is. For one, most studies have been centred in high-income Western countries (Jones et al., 2016); it’s also still largely unclear exactly what a “healthy diet” should consist of, nevertheless what a truly sustainable society would look like. Integrating all of these concepts is an enormous challenge.
