He tikanga māmā noa te whero e tuku ana i ngā roangaru mārama ki ngā kiko o te kiri me te hohonu o raro. Nā te kaha o te mahi koiora, ko ngā roangaru mārama whero me te whero-whero i waenga i te 650 me te 850 nanometer (nm) e kiia ana ko te "matapihi whakaora." Ka tukuna e ngā taputapu whakaora mārama whero ngā roangaru i waenga i te 620-850 nm.
Ka uru atu ēnei roangaru ki roto i te kiri kia tae atu ki ngā pūtau kua pakaru. Kia mimitia ki roto i ngā pūtau, ka whakaoho te mārama whero i te mahi a ngā mitochondria, e mōhiotia ana ko te "pūngao" o te pūtau. Hei tauira, ka hurihia e ngā mitochondria te kai hei momo pūngao e whakamahia ana e te pūtau mō ngā mahi o ia rā. Nō reira, ka whakaoho i te whakaputa pūngao, ā, ka āwhina i ngā pūtau kia ora ake i te kino.
Hei tāpiritanga, ka āwhina hoki ēnei roangaru ki te whakanui ake i te hanga o te waikura hauota e whakawhanui ana i ngā oko toto, e whakarei ake ana i te korikori me te whakaora, ā, e whakaohooho ana hoki i te tukunga o te insulin me te homoni tipu.
He huarahi tere, watea, ā, kāore e pokanoa te whakaora rama whero e rongoā ana i te tini o ngā mate. Ko tētahi o ngā painga nui o te whakaora rama whero ko te taea e ngā kaiwhakarato te whakakotahi me te nuinga o ngā maimoatanga katoa, tae atu ki te whakaora tinana, te rongoā, tae atu ki te whakaora-ā-kanohi. Ko te mea nui, he iti noa iho ngā pānga taha, ngā raruraru rānei e pā mai ana i te whakaora rama, nō reira he haumaru mō te nuinga o ngā tūroro, ā, he mea whakauru ki roto i te nuinga o ngā mahere maimoatanga. Ko te whakaora rama whero tētahi o ngā tāpiri pai rawa atu ka taea e koe te mahi ki tō mahi. E mōhiotia ana ko te whakarerekētanga whakaahua, he whai hua te whakaora rama whero, he utu tika, ā, he tino hiahiatia e ngā kiritaki e hiahia ana ki te tini o ngā maimoatanga kounga teitei, matatau hangarau i te wāhi kotahi.
He maha ngā painga o te whakaora mārama i roto i te rongoā i ngā mate hauora me ngā raruraru hauora, mai i te whakakore i te hakihaki ki te whakahaere i te mamae, te whakapakari i te whakaora wheua ki te whakaiti i te taumaha. Hei tāpiri, ka tāpirihia hoki ki ētahi atu rongoā, pērā i te whakaora kiri, te whakaora kōpeketanga me te maha atu, kia pai ake ai ngā hua rongoā whānui mō ō tūroro.
