Yes. You can bring food into the Coliseum for individual consumption. Clear factory-sealed plastic bottles of water, soda and juice are also permitted.
Oakland Coliseum has a very liberal policy on bringing food into the ballpark which is you can basically bring anything. You are allowed to bring a soft cooler even, with sealed plastic bottles of non-alcoholic drinks and snacks.
Just has to be sealed and plastic. No glass or metal.
