Following ingestion and metabolism, flavones, other polyphenols, and their metabolites are absorbed poorly in body organs and are rapidly excreted in the urine, indicating mechanisms influencing their presumed absence of metabolic roles in the body.
The passage suggests that despite being ingested and metabolized, flavones, along with other polyphenols and their metabolites, do not appear to have significant roles in the body's metabolic pathways. This is indicated by their poor absorption and rapid excretion in urine.
