|The Chocolate Girl by Jean-Étienne Liotard, Gemäldegalerie Alte Meister, Dresden, circa 1743-44|
The chocolatiers were smiling at their unexpected luck
Without a cent of ad expense they stood to make a buck.
A scholar in NEJM 1 first pompously opined
That choc-o -late ingestion may emancipate the mind
And lead to creativity as well as high acclaim
Not just for noble enterprise but also to great fame.
Indeed the very pinnacle of academe’s success
A Karolinska invite for Nobelian address.
Next come more solid findings in a subsequent report 2
Tying chocolate intake to brain health with support.
Before aspiring scientists rush forth to binge on choc
They’d be advised to make quite sure the science isn’t schlock.
Statistics for one “study” 1 was paltry for a start
And cause-effect relationships are, sadly, far apart.
A craving for the cocoa bean is safer than for pot
Though both contain cannabinoids, a little or a lot.
Hedonic urges stimulate release from daily plods
And Aztec xiocolati served as nectar for the gods.
Are flavinoids an elixir that nurtures food for thought
Creating neural crosstalk to a pinnacle that’s sought?
Though genius has been credited to nurture and to genes,
Causation’s far from proven for cacao’s magic beans.
A burst of serotonin sure may stimulate the brain
But in true “Eureka!” moments chocolate may not be germane.
Indeed if ‘twere so simple then a pathway to the Prize
Would be lined with bars of chocolate of ever larger size.
If chance indeed does favor minds prepared by chocolate bars
Did Einstein get his mc-squared through “energy” from Mars?
