The man, who has not been named but was 54 years old, ate about one-and-a-half bags of black Liquorice every day.
He had suffered no symptoms before suddenly going into cardiac arrest in a fast food restaurant.
"We are told that this patient has a poor diet and eats a lot of candy.
He said studies had shown glycyrrhizic acid - the active ingredient in liquorice - could cause "hypertension, hypokalemia, metabolic alkalosis, fatal arrhythmias, and renal failure" - all of which were seen in this patient.
A few weeks before his death, he switched from red fruit-flavoured twists to another type made with black liquorice.
Another doctor, Dr Andrew L Lundquist, agreed in the report that the liquorice was to blame.
