Tuna yo mu macupa ni isoko ikunzwe kandi yoroshye ya poroteyine iboneka mu macupa hirya no hino ku isi. Ariko, kubera impungenge zikomeje kwiyongera ku rugero rwa mercure mu mafi, abantu benshi bibaza umubare w'amacupa ya tuna yo mu macupa bashobora kurya buri kwezi.
FDA na EPA basaba ko abantu bakuru bashobora kurya amafi agera kuri 12 (hafi ebyiri cyangwa eshatu) mu buryo butekanye y’amafi afite mercure nkeya buri cyumweru. Tuna yo mu macupa, cyane cyane tuna yoroshye, ikunze gufatwa nk'amahitamo afite mercure nkeya. Ariko, ni ngombwa gutandukanya ubwoko bwa tuna yo mu macupa iboneka. Tuna yoroshye ikunze gukorwa muri tuna ya skipjack, ifite mercure nkeya ugereranije na tuna ya albacore, ifite mercure nyinshi.
Kugira ngo ugire indyo yuzuye, ni byiza ko utarya ounces zirenze 6 za albacore tuna ku cyumweru, ni ukuvuga ounces 24 ku kwezi. Ku rundi ruhande, tuna yo mu macupa ni nziza cyane, aho igera kuri ounces 12 ku cyumweru, ni ukuvuga ounces 48 ku kwezi.
Mu gihe uteganya kurya tuna yo mu macupa buri kwezi, tekereza gushyiramo izindi poroteyine zitandukanye kugira ngo ugire indyo yuzuye. Ibi bishobora kuba birimo andi moko y'amafi, inkoko, ibinyamisogwe, na poroteyine zikomoka ku bimera. Nanone, menya neza ibyo kurya cyangwa indwara zishobora kugira ingaruka ku mirire yawe.
Muri make, nubwo tuna yo mu macupa ari ibiryo bifite intungamubiri kandi bifite uburyo bwinshi bwo kubikoresha, kugabanya ni ingenzi. Kugira ngo ugire uburinganire, gabanya albacore tuna kugeza kuri ounces 24 ku kwezi na tuna yoroshye kugeza kuri ounces 48 ku kwezi. Muri ubu buryo, ushobora kwishimira ibyiza bya tuna yo mu macupa mu gihe ugabanya ibyago bishobora guterwa na mercure ku buzima.
