I am not entirely sure what you are trying to achieve.  However, I can
say that ignoreheading and block are mutually exclusive environment
settings so you cannot have both.  A block needs a heading but if you
ignore it, you cannot have a block.

The following works, assuming I have understood what you wanted:

#+begin_src org
  ,#+TITLE: test
  ,#+OPTIONS: H:3

  ,#+STARTUP: beamer

  ,* blah
  ,** test
  ,*** Food
  ,**** dummy 1                                                  :BMCOL:
      :PROPERTIES:
      :BEAMER_col: 0.5
      :END:
  ,***** Fruit
       - apple
       - banana
  ,***** Nuts
        - brasil
        - cashew
  ,**** dummy 2                                                  :BMCOL:
      :PROPERTIES:
      :BEAMER_col: 0.5
      :END:
  ,***** Vegetables
       - artichoke
       - broccoli
  ,***** Pulses
       - chickpea
       - lentil
#+end_src

If you want a block with an empty heading, use a non-printing space of
some sort for the heading, maybe @@latex:~@@?
