In August, researchers from the University of California, Berkeley published their findings that wild green “weeds” growing in abundance in the poor, urban areas of San Francisco, California contain more nutrition than grocery store produce, even despite the drought in California.
About nine city blocks worth of wild greens were collected from three separate areas by the researchers, led by Philip Stark. The neighborhoods were described as “disadvantaged neighbourhoods surrounded by busy roads and industrial zones.”
According to Cosmos, “The areas, classified as “urban food deserts”, are more than one to one-and-a-half kilometres from the nearest shop that sells fresh produce. Six different species were tested for nutrition content: chickweed (Stellaria media), dandelion (Taraxacum officinale), dock (Rumex crispus), mallow (Malva sylvestris), nasturtium (Tropaeolum majus) and oxalis (Oxalis pescaprae). All compared favourably to kale – arguably one of the most nutritious domesticated greens – for several nutrients.”
