Langoustine Nutrition Benefits and Facts

Nutritional summary

Langoustines are a source of long-chain omega-3 fatty acids, specifically EPA and DHA, which are well-established for their role in cardiovascular health and are linked to a reduced risk of metabolic liver dysfunction .
These crustaceans are benthic (bottom-dwelling) scavengers, a lifestyle that makes them notably vulnerable to ingesting microplastics found in seafloor sediments .
While research has found microplastics in the stomachs and intestines of up to 100% of langoustine samples in some regions, current evidence suggests the actual health risk to humans is likely negligible, as the exposure from seafood is only a small fraction of total daily dietary intake .
Early research indicates that the retention of microplastics in langoustines may be influenced by the specific morphology (physical structure) of their gut, though the long-term implications for human consumers remain a subject of ongoing study .

Interesting fact

Also known as the Dublin Bay Prawn, this species lives in complex burrow systems on the seabed and was historically considered a nuisance by-catch before becoming a luxury culinary staple.
