Arachidonic acid (ARA), docosahexaenoic acid (DHA) uye eicosapentaenoic acid (EPA) iketani refu polyunsaturated fatty acids (LCPUFA). Carotenoids, kusanganisira lutein uye zeaxanthin (LZ), inonyanya kuwanikwa mumiriwo mitema.
ARA neDHA zvakawanda muuropi uye zvikamu zvikuru zvephospholipids. Zvidzidzo zvakaratidza kuti kuwedzera madosi akakwira eDHA neEPA kunogona kuvandudza ndangariro basa muvakuru vakuru.
Mukuwedzera, LZ, iyo antioxidant chikamu chehuropi, yakanzi ine inodzivirira pamasero etsinga, nekudaro inokanganisa kugona kwekuziva. Nekudaro, kushanda kwe lutein uye zeaxanthin pane ndangariro basa hakuna kujeka nekuda kwekupokana mhedzisiro kubva kune yapfuura kupindira zvidzidzo.
Zvichienderana nenyaya yekuti ARA, DHA, EPA, L uye Z (LCPUFA + LZ) iripo muuropi, pamwe nemimwe mishumo yekuvandudzwa kwekuyeuka basa, vanyori veongororo yazvino vakaratidza kuti kusanganiswa kwezvinhu izvi kunogona kuvandudza. ndangariro. kushanda muuropi. vanhu vakura vane utano hwakanaka.
Vatsvakurudzi veJapan vakaita 24-vhiki, randomized, kaviri-mapofu, placebo-inodzorwa, yakafanana neboka rekudzidza pamusoro pemigumisiro yeLCPUFA + LH pamusoro pebasa rekuyeuka muhutano hwevanhu vechiJapan vakwegura vane zvinetso zvekuyeuka asi vasina kuora mwoyo.
Havana kuwana misiyano yakakosha pakati pemapoka. Zvisinei, mukuongororwa kwakabatanidzwa kweboka revatori vechikamu vane kuderera kwekuziva, kuvandudzwa kukuru kwakaonekwa.
Mushumo wacho unopedzisa kuti: "Ichi chidzidzo chinoratidza kekutanga kuti kusanganiswa kweLCPUFA neLZ kunogona kuvandudza kushanda kwendangariro muvakuru veJapan vane hutano vakura vane pfungwa dzakadzikira asi vasina dementia." 'chinyorwa ad1′); });
Zvose zvevatori vechikamu 120 kubva kuTokyo uye nzvimbo dzakapoteredza dzakasarudzwa kuva mapoka matatu: (1) boka re placebo rinogamuchira placebo sekuwedzera kwezvokudya; (2) boka re placebo rinogamuchira placebo sechikafu chekuwedzera; (2)). LCPUFA + X boka rakagamuchira chekuwedzera chekudya chinosanganisira LCPUFA (ine 120 mg ARA, 300 mg DHA uye 100 mg EPA pazuva) neCompound X (isina kuratidzwa sezvo komisheni iyi yakanga isiri nyaya yechidzidzo ichi) (3) LCPUFA +LH boka rinowana chekuwedzera chekudya chinosanganisira LCPUFA (120mg ARA, 300mg DHA uye 100mg EPA pazuva) pamwe neLH (10mg lutein uye 2mg zeaxanthin pazuva).
Chikafu chekuyedza uye zvekushandisa zvechidzidzo ichi zvakapihwa neSuntory Health Co., Ltd., iyo inotengesa hutano chikafu chine LCPUFA.
Iyo yakagadziridzwa Wechsler Logical Memory Scale II (WMS-R LM II) uye Montreal Cognitive Test muchiJapan (MoCA-J) yakashandiswa pakuongorora.
Zera, murume kana mukadzi, uye dzidzo zvakanyorwa sehunhu hwevatori vechikamu. Ropa sampuli dzakaunganidzwa pakutanga, vhiki 12 uye 24 yemafuta acid uye LZ kuongororwa.
Neuropsychological test yakaitwa uye kudya kwemafuta acid kutorwa kwakayerwa pakutanga, pa12 uye 24 mavhiki. Mumwe nemumwe anotora chikamu akapedzisa dhayari, achirekodha kuwedzera kudya uye kutarisa shanduko huru yemararamiro.
Zvakawanikwa zvakaratidza kuti LCPUFA + LZ yakanga isina chinhu chakakosha pakurangarira basa muvanhu vakura veJapan vane hutano vane matambudziko ekurangarira, asi chekuwedzera chakavandudza ndangariro basa muvatori vechikamu vane kuderera kwekuziva.
Vanyori vanoti zvidzidzo zvekupindira mune remangwana zvichibva paruzivo rwakadzama rwevatambi vekutanga cognitive performance ichabatsira kuita mitongo yakakodzera nezve mhedzisiro yekupindira pandangariro basa.
"Mhosva ye-long-chain polyunsaturated fatty acids musanganiswa ne lutein uye zeaxanthin pane episodic memory muvanhu vakura vane hutano"
