Abstract

Recent research has indicated a potential link between specific diets and an increased risk of stroke or cardiovascular disease. In this report, we describe a case involving a 45-year-old male who consumed a nightly diet consisting entirely of convenience store bento or cup noodle ramen for over two decades. After two decades of this diet, he experienced a bilateral internal carotid artery dissection in the petrous and cervical portions in his 40s. This condition resulted in an infarction in the left middle cerebral artery area. After stroke treatment, he was discharged and went home without any sequelae. There was no recurrence of stroke after his diet was adjusted appropriately. Although this is a single case study and we cannot exclude that an unbalanced diet is not the cause, it highlights that certain extreme dietary habits may pose a risk of early-onset artery dissection.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
