Thanks, this works (I'm using 8.3.3).  Now I am wondering whether it is
possible to have two headings in the same columns of the same order?  I
thought that I would need a dummy heading between "Food" and "Fruit",
but the following does not work (everything ends up in a single
column).  Even if it had worked, presumably it would have changed the
formatting, since '**** Fruit' is now '***** Fruit', or should
'ignoreheading' handle that?

This is what I tried but only got a single column:

#+TITLE: test
#+OPTIONS: H:3
#+STARTUP: beamer

* blah
** test
*** Food
**** dummy 1                                                  :B_block:BMCOL:
    :PROPERTIES:
    :BEAMER_col: 0.5
    :BEAMER_env: block
    :BEAMER_env: ignoreheading
    :END:
***** Fruit
     - apple
     - banana
***** Nuts
      - brasil
      - cashew
**** dummy 2                                                  :B_block:BMCOL:
    :PROPERTIES:
    :BEAMER_col: 0.5
    :BEAMER_env: block
    :BEAMER_env: ignoreheading
    :END:
***** Vegetables
     - artichoke
     - broccoli
***** Pulses
     - chickpea
     - lentil

Cheers,
