He ʻeke paʻakai iodized ka hapa nui o ka poʻe i kā lākou lumi kuke. Kākau nā mea hana ma nā pūʻulu paʻakai e hoʻonui ʻia ka huahana me ka iodine. Maopopo iā ʻoe ke kumu i hoʻohui ʻia ai ka iodine i ka paʻakai? Ua manaʻo ʻia ʻaʻole nele nā kānaka i ka iodine i kā lākou ʻai i kēlā me kēia lā, akā
A wahi o ka moolelo
Ua hoʻomaka ka hoʻohui ʻia ʻana o Iodine i ka paʻakai i ka makahiki 1924 ma ʻAmelika Hui Pū ʻIa, ma muli o ka ulu pinepine ʻana o nā maʻi goiter (maʻi thyroid) ma nā Lakes Nui a me ka ʻĀkau Komohana o ka Pākīpika. ʻO kēia ma muli o ka haʻahaʻa o ka iodine i loko o ka lepo a me ka nele i ka meaʻai.
Ua ʻae ka poʻe ʻAmelika i ka hana Swiss e hoʻohui i ka iodine i ka paʻakai papa e hoʻonā i ka pilikia. ʻAʻole i liʻuliʻu, ua emi nā hihia o ka maʻi thyroid a ua lilo ka hana i mea maʻamau.
Hoʻohana ʻia ka paʻakai ma ke ʻano he mea lawe iodine no ka mea he ala maʻalahi ia e hoʻokomo i ka micronutrient i kāu ʻai i kēlā me kēia lā. ʻAi ʻia ka paʻakai e nā mea a pau a mau loa. ʻO ka meaʻai pipi i hoʻomaka e hoʻohui i ka paʻakai iodized.
He aha ka paʻakai weliweli me ka iodine?
Ua loli kēia mai ka makahiki 20 ma muli o ka hana ʻana i nā kemika ʻawaʻawa a me nā ala ʻoi aku ka maikaʻi o ka ʻohi paʻakai. I ka wā ma mua, ua ʻeli ʻia ka hapa nui o ka paʻakai mai ke kai a i ʻole mai nā waihona kūlohelohe. ʻO ka paʻakai iodized ʻaʻole ia he hui kūlohelohe, akā hana ʻia ka sodium chloride me ka hoʻohui ʻana o ka iodide.
Loaʻa ka iodide synthetic additive i loko o nā meaʻai i hana ʻia - nā meaʻai i hana ʻia a me nā meaʻai hale ʻaina. Hiki iā ia ke sodium fluoride, potassium iodide - nā mea ʻawaʻawa. I ka noʻonoʻo ʻana i ka paʻakai papaʻaina i bleached, ʻaʻole hiki ke manaʻo ʻia he kumu ola iodine.
Eia naʻe, pono maoli ka iodine no ka thyroid gland e hana i ka thyroxine a me ka triiodothyronine, ʻelua mau hormones nui no ka metabolism. Hāʻawi kekahi ʻano iodine i ka hana ʻana o nā hormones thyroid T4 a me T3.
ʻO kahi haʻawina i hana ʻia ma ke Kulanui o Texas ma Arlington e ʻōlelo nei ʻaʻole i pale ka paʻakai i ka nele o iodine. Ua loiloi nā kānaka ʻepekema ma mua o 80 mau ʻano paʻakai pāʻoihana a ʻike ʻia he 47 o lākou (ʻoi aku ma mua o ka hapalua!) ʻAʻole i hoʻokō i nā kūlana US no nā pae iodine. Eia kekahi, ke mālama ʻia i loko o nā kūlana haʻahaʻa, e emi ana ka ʻike iodine i loko o ia mau huahana. Ka hopena: ʻo 20% wale nō o ka nui o ka paʻakai iodized hiki ke noʻonoʻo ʻia he kumu o ka ʻai iodine i kēlā me kēia lā.
