Food is a thing that is also a part of oneself and so belongs both to the empathic, right hemisphere side of knowledge as well as to the abstract, left hemisphere side. Musical instruments also are part of what gets processed by the right hemisphere. That's probably why the heart is on the left side of the body: it is managed by the right side of the brain.
Things that have utility, tools that can be employed, get coded into the left hemisphere. Words, language and man-made concepts are man-made and belong to the left hemisphere.
"... the affinity of the left hemisphere for everything it has itself made ("fruits of human invention") in contrast to the affinity of the right hemisphere for what exists before and after – and beyond – ourselves, namely nature." (The Master and His Emissary, Iain McGilchrist, 2009; page 56).
The more habituated and predictable something becomes the more likely it will be processed by the left hemisphere where things that are lifeless are dealt with.
