      Pistachios are native to Iran, and until the 1970s Iran was the world’s largest exporter. They dyed their exports with a food safe red.

        They were dyed because they were hand picked and oils from the pickers hand would cause discoloration. The red dye covered that up.

        Machine harvested pistachios didn’t have that problem.
