Italian calamari stew: about squids
Squid is a member of the mollusc family, more precisely the cephalopod family (cuttlefish, squid, octopus). Molluscs provide good amounts of iron and calcium, and cephalopods in particular contain moderate amounts of purines.
What are purines? Purines are molecules found in DNA and RNA, and are divided into endogenous (produced by the body) and exogenous (taken in with food). The latter are metabolised by the liver, which produces uric acid, a waste product that is first released into the bloodstream and then excreted in the urine.
However, uric acid can accumulate in the bloodstream and give rise to hyperuricemia, which can lead to kidney stones or gout. So we should be careful about the amount of purines we consume, which are rich in alcohol and saturated fats.
