Hoʻokomo

ʻO ka Tuna kahi iʻa wai paʻakai e ʻai ʻia ma ka honua holoʻokoʻa.

He mea momona maikaʻi loa ia a me kahi kumu waiwai nui o ka protein, omega-3 fatty acid a me nā huaora B. Eia nō naʻe, hiki ke komo i loko o nā kiʻekiʻe o ka mercury, kahi mea kaumaha kaumaha.

Nā hana kūlohelohe - e like me nā pele pele - a me nā hana ʻoihana - e like me ke kuni ʻana i ka lānahu - hoʻokuʻu i ka mercury i ka lewa a i ʻole i loko o ke kai, a ma ia manawa hoʻomaka ia e kūkulu i ke ola kai.

Hoʻohui ʻia ka nui loa o ka mercury i nā pilikia olakino koʻikoʻi, e hāpai ana i nā hopohopo e pili ana i ka lawe maʻamau o ka tuna.

Nānā kēia ʻatikala i ka mercury i ke tuna a haʻi iā ʻoe inā palekana ke ʻai ʻana i kēia iʻa.

Pehea ka haumia?

Aia ʻo Tuna he mercury i ʻoi aku ma mua o nā mea iʻa iʻa e kaulana ʻia, e like me ka salemona, nā ʻōlio, ka ʻula, nā scallops a me ka tilapia ().

ʻO kēia ke kumu no ka hānai ʻana o ke tuna i nā iʻa liʻiliʻi i hoʻohaumia ʻia me nā mercury like ʻole. Ma muli o ka maʻalahi ʻole o ka mercury e kinai ʻia, kūkulu ia i loko o nā aʻa o ka tuna ma kahi o ka manawa (,).

Nā pae ma nā ʻano mea like ʻole

Ana ʻia nā pae o ka mercury i ka iʻa i nā ʻāpana o kēlā me kēia miliona (ppm) a i ʻole nā ​​micrograms (mcg). Eia kekahi ʻano tuna maʻamau a me kā lākou mercury concentrations ():

Nā Hana Loiloi a me nā pae palekana

Ua ʻōlelo ʻo ka US Environmental Protection Agency (EPA) ʻo 0.045 mcg o ka mercury no ka paona (0.1 mcg per kg) o ke kaumaha o ke kino i kēlā me kēia lā ka hopena palekana ʻoi loa o ka mercury. ʻIke ʻia kēia nui ma ke ʻano he dālā kuhikuhi (4).

ʻO kāu lāʻau i kēlā me kēia lā no ka mercury pili i kou kaumaha o ke kino. ʻO ka hoʻonui ʻana i kēlā helu me ʻehiku hāʻawi iā ʻoe i kāu palena o ka mercury i kēlā me kēia pule.

Eia kekahi mau laʻana o nā kūmole kūmole e pili ana i nā kaupaona o ke kino.

Ma muli o ke kiʻekiʻe loa o kekahi ʻano tuna i ka mercury, hiki i kahi 3-auneke (85-gram) lawelawe ke loaʻa i kahi mercury konsentration e kūlike a ʻoi paha ma mua o ka helu o kēlā me kēia pule.

Kiʻekiʻe ʻo Tuna i ka mercury ke hoʻohālikelike ʻia me nā iʻa ʻē aʻe. ʻOi aku kahi lawelawe o kekahi ʻano tuna ma mua o ka nui o ka mercury e hiki ai iā ʻoe ke hoʻopau palekana i kēlā me kēia pule.

Nā pilikia o ka Mercury Exposure

He hopohopo olakino ka Mercury i ka tuna ma muli o nā pilikia e pili ana i ka hōʻike ʻana o ka mercury.

E like me ke kūkulu ʻana o ka mercury i nā iʻa iʻa i ka holo ʻana o ka manawa, hiki nō ke hōʻiliʻili i loko o kou kino. I mea e loiloi ai i ka nui o ka mercury i loko o kou kino, hiki i ke kauka ke hoʻāʻo i nā kukuna mercury i kou lauoho a me kou koko.

Hiki i nā pae kiʻekiʻe o ka mercury ke alakaʻi i ka make o ka lolo a hopena i nā mākau kaʻa maikaʻi maikaʻi ʻole, hoʻomanaʻo a me ka nānā ().

I hoʻokahi noi i 129 mau mākua, ʻo ka poʻe me ke kiʻekiʻe o ka mercury i hana ʻoi aku ka maikaʻi ma luna o nā motika maikaʻi, noʻonoʻo a me nā hoʻomanaʻo hoʻomanaʻo ma mua o ka poʻe i loaʻa nā pae haʻahaʻa o ka mercury ().

Hiki i ke kuhi Mercury ke alakaʻi i ka hopohopo a me ke kaumaha.

ʻO kahi noiʻi i nā mākua i hōʻike ʻia i ka mercury ma ka hana i ʻike ua ʻike lākou i ka nui o ke kaumaha a me nā ʻōuli hopohopo a ua lohi i ka hana ʻana i ka ʻike ma mua o ka poʻe komo ().

ʻO ka hope loa, pili ka mercury buildup i kahi kiʻekiʻe o ka maʻi puʻuwai. ʻO kēia paha ma muli o ka hana a ka mercury i ka hoʻohaʻahaʻa momona, kahi hana e hiki ai ke alakaʻi i kēia maʻi ().

I loko o kahi noiʻi ma luna o 1,800 mau kāne, ʻo ka poʻe i ʻai i ka iʻa nui a loaʻa ka nui o ka mercury concentrations he ʻelua mau manawa likelier e make i ka maʻi puʻuwai a me nā maʻi puʻuwai ().

Eia nō naʻe, hōʻike ʻia kahi noiʻi ʻē aʻe ʻaʻole pili ka hōʻike ʻana o ka mercury kiʻekiʻe me ka hoʻonui ʻana o ka maʻi puʻuwai a ʻoi aku ka maikaʻi o ka ʻai ʻana i ka iʻa no ke olakino puʻuwai ma mua o nā pilikia e hiki ai ke komo i ka mercury ().

ʻO Mercury kahi metala kaumaha e hiki ai ke hopena i nā hopena olakino maikaʻi. Hiki i nā concentrations kiʻekiʻe o ka mercury i ke kanaka ke hoʻomaka i nā pilikia o ka lolo, ke olakino olakino maikaʻi ʻole a me nā maʻi puʻuwai.

Ehia mau manawa e ʻai ai ʻoe i ke kapa?

Nui ka momona o ka Tuna a piha pū me ka protein, nā momona momona a me nā huaora - akā ʻaʻole pono ia e hoʻopau ʻia i kēlā me kēia lā.

Paipai ka FDA i nā mākua e ʻai i ka ʻaukā he5 (85-140 gram) o ka iʻa 2-3 mau manawa i ka hebedoma e lawa ai ka nui o ka omega-3 fatty acid a me nā mea kōkua maikaʻi ʻē aʻe ().

Eia nō naʻe, hōʻike ka noiʻi i ka ʻai mau ʻana i ka iʻa me ka nui o ka mercury i ʻoi aku ma mua o 0.3 ppm hiki ke hoʻonui i nā pae o ke koko a me nā pilikia olakino. ʻO ka hapa nui o nā ʻano tuna ma mua o kēia nui (,).

No laila, pono ka hapanui o nā mākua e ʻai i ka tuna me ka noʻonoʻo a koho i nā iʻa ʻē aʻe haʻahaʻa i ka mercury.

Ke kūʻai ʻana i ke tuna, e koho no ka skipjack a i ʻole nā ​​ʻano māmā i hiki ʻole ke mālama ʻia, e like me ka albacore a i ʻole bigeye.

Hiki iā ʻoe ke ʻai i ke tuna māmā a me nā tuna māmā i ka pili o nā ʻano mercury ʻē aʻe, e like me ka cod, crab, salmon a me scallops, ma ke ʻano he ʻāpana o ka iʻa i manaʻo ʻia he 2-3 i kēlā me kēia pule ().

E hoʻāʻo e hōʻole i ka ʻai ʻana i ka tuna albacore a i ʻole yellowfin tuna ma mua o hoʻokahi manawa i kēlā me kēia pule. E hōʻole i ka tuna bigeye i ka hiki ().

Hiki ke ʻai ʻia ʻo Skipjack a me nā tuna māmā i hiki ke ʻai ʻia ma ke ʻano he haʻahaʻa o ka mercury. Eia nō naʻe, kiʻekiʻe nā albacore, yellowfin a me bigeye tuna i ka mercury a pono e kaupalena ʻia a pale ʻia paha.

Pono kekahi poʻe e hōʻalo iā Tuna

Kūpono ʻia kekahi mau heluna i ka mercury a pono e kaupalena a i ʻole hōʻole loa ʻia mai ka tuna.

Hoʻopili kēia i nā pēpē, nā keiki ʻōpio a me nā wahine hāpai, hānai hānai a i ʻole ke hoʻolālā ʻana e hāpai.

Hiki i ka Mercury ke hoʻopili i ka ulu ʻana o ka embryo a alakaʻi i nā pilikia o ka lolo a me ka ulu ʻana.

I loko o kahi noiʻi i loko o 135 mau wahine a me kā lākou pēpē, ua hoʻopaʻa ʻia kēlā me kēia ppm o ka mercury i hoʻopau ʻia e nā wahine hāpai i ka hoʻoliʻiliʻi o ʻehiku mau helu ma nā helu hōʻike o ka hana o ka lolo.

Eia naʻe, ua ʻike ʻia ke aʻo ʻana ua pili ka iʻa mercury haʻahaʻa me nā helu ʻoi loa o ka lolo ().

Kūkākūkā nā luna olakino i kēia manawa nā keiki, nā wahine hāpai a me nā makuahine hānai e kaupalena i ka lawe ʻana i ke tuna a me nā iʻa mercury kiʻekiʻe ʻē aʻe, no ka ʻimi ʻana i nā lawelawe he 2-3 o ka iʻa mercury haʻahaʻa i kēlā me kēia pule (4,).

ʻO nā pēpē, nā keiki a me nā wahine hāpai, hāpai hānai a hoʻāʻo paha e hāpai e kaupalena a pale i ka tuna. Eia nō naʻe, pōmaikaʻi paha lākou i ka ʻai ʻana i ka iʻa mercury haʻahaʻa.

Ka Laina Lalo

Pili ka wai Mercury i nā pilikia olakino e pili ana i ka hana lolo maikaʻi ʻole, ka hopohopo, ke kaumaha, ka maʻi puʻuwai a me ka ulu ʻana o ka pēpē maikaʻi ʻole.

ʻOiai he momona nui ka tuna, kiʻekiʻe pū kekahi i ka mercury ke hoʻohālikelike ʻia i ka nui o nā iʻa ʻē aʻe.

No laila, pono e ʻai ʻia me ke kūpono - ʻaʻole i kēlā me kēia lā.

Hiki iā ʻoe ke ʻai i ke kikaki a me nā lawaiʻa kēpau māmā ma ka ʻaoʻao o nā iʻa mercury haʻahaʻa i kekahi mau manawa i kēlā me kēia pule, akā pono e kaupalena a pale paha i ka albacore, yellowfin a me bigeye tuna.
