Be sure you buy shellfish from a reliable vendor to avoid food-borne illness. Some processed or frozen seafood is very high in sodium and should therefore be limited.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
But eating raw oysters and other undercooked seafood can put you at risk for infections, including vibriosis. Vibriosis is caused by infection with some kinds of Vibrio bacteria (germs). Vibrio naturally live in certain coastal waters.
