ʻO kaʻaiʻana i nā huaʻai a me nā huaʻai i'ōlelo pinepineʻia no ka hoʻohaʻahaʻa kaumaha no ka mea e hōʻoluʻolu iāʻoe, akā hiki ke lilo i mea make, e like me kahi noiʻi hou mai ke Kulanui o Alabama ma Birmingham, i paʻiʻia ma ka American Journal of Clinical Nutrition.
Wahi a ka USDA's My Plate Initiative, ʻo ka lawelawe ʻana i kēlā me kēia lā no nā pākeke he 1,5-2 kīʻaha hua a me 2-3 kīʻaha o nā mea kanu. Katherine Kaiser, PhD, AUB Public Health Faculty Instructor, a me kahi hui o nā mea noiʻi me Andrew W. Brown, PhD, Michelle M. Moen Brown, PhD, James M. Shikani, Dr. Ph. a me David B. Ellison, PhD, a Ua alakaʻi nā mea noiʻi o ke Kulanui ʻo Purdue i kahi loiloi ʻōnaehana a me ka meta-analysis o nā ʻikepili mai nā mea ʻoi aku ma mua o 1200 mau mea i komo i loko o ʻehiku mau hoʻokolohua hoʻokele randomized e kālele ana i ka hoʻonui ʻana i ka nui o nā huaʻai a me nā mea kanu i ka meaʻai a me ka hopena i ka pohō kaumaha. Ua hōʻike nā hopena i ka hoʻonui ʻana i ka ʻai ʻana i nā huaʻai a me nā mea kanu wale nō ʻaʻole i emi ke kaumaha.
"Ma ke ʻano holoʻokoʻa, ʻo nā haʻawina āpau a mākou i nānā ai e hōʻike ana ʻaʻohe hopena i ka pohō kaumaha," wahi a Kaiser. “No laila ʻaʻole pono ʻoe e ʻai i mea e lilo ai ke kaumaha. Inā hoʻohui ʻoe i nā huaʻai a me nā mea kanu i ka meaʻai maʻamau, ʻaʻole paha ʻoe e lilo i ke kaumaha. ʻOiai he nui ka poʻe e manaʻoʻiʻo hiki i ka hua ke hoʻonui iā ʻoe i ke kaumaha, ʻōlelo ʻo Kaiser ʻaʻole i ʻike ʻia kēia me ke ʻano.
"Ua ʻike ʻia inā ʻoe e ʻai i nā huaʻai a me nā mea kanu, ʻaʻole ʻoe e loaʻa ke kaumaha, ʻo ia ka maikaʻi no ka mea hiki iā ʻoe ke loaʻa i nā huaora a me ka fiber," wahi āna. ʻOiai ʻo ia e ʻae nei i nā pono olakino o nā huaʻai a me nā mea kanu, ke nīnau mau ʻia nei kā lākou pōmaikaʻi hoʻemi kaumaha.
"Ma ka pōʻaiapili maʻamau o ka meaʻai olakino, kōkua ka hoʻemi ʻana i ka ikehu e hōʻemi i ke kaumaha, a no ka hōʻemi ʻana i ka ikehu, pono ʻoe e hoʻemi i ka nui o nā calorie i ʻai ʻia," wahi a Kaiser. - Manaʻo ka poʻe e hoʻololi nā huaʻai a me nā huaʻai momona i ka meaʻai liʻiliʻi a hoʻomaka i ka hana hoʻemi kaumaha; ʻO kā mākou noiʻi, akā naʻe, ʻaʻole hiki kēia i ka poʻe e hoʻomaka wale ana e ʻai i nā huaʻai a me nā mea kanu.
"Ma ke olakino lehulehu, makemake mākou e hāʻawi i nā poʻe i nā leka maikaʻi a hoʻokiʻekiʻe, a ʻo ka haʻi ʻana i ka poʻe e ʻai i nā huaʻai a me nā mea kanu ʻoi aku ka maikaʻi ma mua o ka ʻōlelo ʻana "e ʻai liʻiliʻi." ʻO ka mea pōʻino, me he mea lā inā hoʻomaka ka poʻe e ʻai i nā huaʻai a me nā mea kanu, akā ʻaʻole e hōʻemi i ka nui o ka meaʻai, ʻaʻole e loli ke kaumaha, "wahi a ka mea noiʻi kiʻekiʻe ʻo David W. Ellison, PhD, dean o ka ʻepekema kūlohelohe ma ka UAB Institute of Ola Ola.
No ka mea maʻamau kēia ʻōlelo aʻoaʻo, manaʻo ʻo Kaiser e hoʻololi nā ʻike.
Nui nā haʻawina kahi e hoʻolilo ai ka poʻe i ka nui o ke kālā e hoʻāʻo e ʻike pehea e hoʻonui ai i kā lākou ʻai ʻana i nā huaʻai a me nā mea kanu, a he nui nā pōmaikaʻi mai kēia; akā, ʻaʻole hoʻokahi o lākou ka poho kaumaha," wahi a Kaiser. "Manaʻo wau ʻo ka hana ʻana i kahi hoʻololi o ke ʻano o ka nohona ʻoi aku ka maikaʻi o ke kālā a me ka manawa."
Ua ʻōlelo ʻo Kaiser, pono e noiʻi hou aku e hoʻomaopopo i ka pili ʻana o nā meaʻai like ʻole no ka pohō kaumaha.
"Pono mākou e hana i kahi noiʻi mechanistic e hoʻomaopopo i kēia, a laila hiki iā mākou ke hoʻomaopopo i ka lehulehu i ka mea e hana ai inā loaʻa kahi pilikia o ke kaumaha. ʻAʻole maikaʻi loa ka ʻike maʻalahi, "wahi āna.
