All I know is that years ago the U sent some emails about that advisory board, video of them trying out food items to be served at gameday ... I guess giving input on other things.
The U has really put extra effort into the gameday experience and etc, but I've no idea who the advisory board is or if they're very active anymore.
Even just going by this forum ... not sure I would want the U to take them TOO SERIOUSLY ... sometimes catering to the "same old fans" isn't the way to the future and there's no reason to think they've got great ideas. They might but ... not a sure thing.
