It's mid-afternoon and time for a treat! Do you choose a healthy piece of fruit, or do you head straight for the chocolate?  It turns out that well before we consciously decide what we're going to eat, our brain has already weighed up our choices — and in a fraction of a second.  Now a new study shows which food attributes are processed by our brain faster than others, and how this might influence our dietary decisions.  You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).
