Hi, can anyone explain this sentence to me? The text warns to pay attention to the salt hidden in food. "Greifen Sie außerdem ab und an bewusst zu salzarmen Lebensmitteln wie Kartoffeln, Nudeln..." Is the separable verb abgreifen of zugreifen, or both? There are too many preposition (what an refers to?) and I can't see the structure. Thanks for your help.
