As an environmental scientist, I am always trying to highlight sustainable ingredients. Broccoli, when sourced locally and in season, is considered a sustainable crop.
Broccoli is a cruciferous vegetable. Like other vegetables in this category, they naturally produce insect-deterring plant compounds, meaning they do not require many pesticides to thrive.
They also have a relatively low water footprint.
