I see a lot of discussion of nutrient content of farmed vegetables here. A cheap and easy alternative to farmed greens lies in foraging wild weeds. Reports from scientists at UC Berkeley have found that toxins like heavy metals, PCBs, etc don't bioaccumulate in these wild greens, so that's great. They rival kale and spinach in their nutritive value. And they're free! Learn to reliably identify the weeds around you and you'll find tons of joy in weeding your backyard or foraging at a park and getting a dinner salad (or bathua ka saag, or quelites, or horta, or minestrella soup) out of it. And it's incredibly unlikely someone's going to be pissed at you for picking their dandelions/purslane/cat's ear/goosefoot/plantain. (Do avoid areas that have had pesticide applied.) https://cosmosmagazine.com/biology/weeds-growing-in-poor-city-areas-more-nutritious-than-store-bought-produce/ https://cosmosmagazine.com/biology/weeds-growing-in-poor-cit... https://www.biorxiv.org/content/10.1101/385864v1 https://www.biorxiv.org/content/10.1101/385864v1
