Hiki i ke kaʻina hana kūpono o ka digestion ke loaʻa wale i ka hihia o ka hui pū ʻana o nā huahana, ʻo ia hoʻi nā protein, nā momona a me nā kalapona, i ka manawa hoʻokahi. ʻAʻole hiki i ka ʻōpū ke hoʻolako i ke kino i nā calorie a me nā huaora i loaʻa mua i nā meaʻai i ʻai ʻia.
Ma ka ʻatikala e kamaʻilio mākou e pili ana i nā lula kikoʻī no nā meaʻai ʻokoʻa. ʻAʻole i ʻōlelo ʻia ka berena, ka ʻuala, ka pī, ka pī, ka maiʻa, nā lā a me nā mea momona ʻē aʻe e ʻai ʻia i ka manawa like me ka lemona, ka lime, ka ʻalani, ka hua waina, ka pineapple a me nā huaʻawaʻawa ʻē aʻe. ʻO ka enzyme ptyalin wale nō ka hana ma kahi ʻano alkaline. ʻAʻole wale nā huaʻona hua e pale i ka digestion o nā waikawa, akā hoʻoikaika pū i kā lākou fermentation. ʻAʻole pono e ʻai ʻia nā ʻōmato me nā meaʻai starchy. E ʻai pū me nā momona a i ʻole nā ʻōmaʻomaʻo. ʻOkoʻa nā kaʻina hana o ka assimilation o nā carbohydrates (starches and sugars) a me nā protein mai kekahi i kekahi. ʻO ke ʻano kēia, ʻaʻole ʻae ʻia nā nati, ka paʻakai, nā huahana waiū i ka manawa like me ka berena, ka ʻuala, nā hua ʻono, nā pies a pēlā aku. ʻO nā mea ʻono (a me ke kō i hoʻomaʻemaʻe ʻia ma ke ʻano maʻamau) e hoʻopau i ka huna ʻana o ka wai ʻōpū i ka nui, e hoʻopaneʻe loa i ka ʻai ʻana. ʻO kaʻaiʻana i nā mea nui, ke kāohi nei lākou i ka hana o ka'ōpū. ʻElua mau meaʻai protein o ke ʻano like ʻole (no ka laʻana, ka paʻakai a me nā nati) e koi i nā ʻano wai like ʻole o ka ʻōpū no ka lawe ʻana. Pono e lawe ʻia ma ke ʻano he lula: i ka ʻai hoʻokahi - hoʻokahi ʻano protein. No ka waiū, makemake ʻia e hoʻohana kaʻawale i kēia huahana mai nā mea ʻē aʻe. Hoʻemi ka momona i ka hana o nā ʻōpū o ka ʻōpū, e pale ana i ka hana ʻana o ka wai ʻōpū no ka hoʻoemi ʻana i nā nati a me nā protein ʻē aʻe. Hoʻemi ka momona momona i ka nui o ka pepsin a me ka waika hydrochloric i loko o ka ʻōpū. ʻO Jelly, jams, huaʻai, syrups, meli, molasses - ʻai mākou i kēia mau mea a pau mai ka berena, nā keke, nā ʻuala, nā cereals, inā ʻaʻole ia e hoʻoulu i ka fermentation. ʻO nā pies wela me ka meli, e like me kāu e hoʻomaopopo ai, mai ka manaʻo o ka meaʻai kaʻawale, ʻaʻole ʻae ʻia. ʻOi aku ka wikiwiki o ka monosaccharides a me ka disaccharides ma mua o ka polysaccharides a makemake i ka ferment i loko o ka ʻōpū, e kali ana i ka ʻai ʻana o nā starches.
Ma ka hahai ʻana i nā loina maʻalahi i helu ʻia ma luna, hiki iā mākou ke mālama i ke olakino o kā mākou ʻōpū ʻōpū a me ke kino holoʻokoʻa holoʻokoʻa.
