Timpeallacht bhia
Bia ultra-próiseáilte agus meáchan coirp
Tá an comhoiriúnacht láidir, comhoiriúnach agus athdhéanta trasna athbhreithnithe uilíocha. Cad a chiallaíonn sé, agus cad atá "ultra-prosessed" ag roghnú, is ceist níos deacra í.
Cad a fuair na hathbhreithnithe
Tuairiscíonn athbhreithniú uilíoch le meta-anailísí nuashonraithe [1] agus athbhreithniú uilíoch comhthreomhara ar thorthaí sláinte diúltacha [2] comhoiriúnachtaí comhoiriúnacha idir níos mó iontógáil bia ultra-prosessed agus torthaí níos measa trasna go leor pointe. Clúdaíonn meta-anailísí dírithe riosca obezity i ndaoine fásta [4], iontógáil obezity agus coinníollacha gaolmhara [5], riosca ailse [3] agus stádas sláinte ginearálta [6].
Tá an comhoiriúnacht go fírinneach impresseach. Tá treo an éifeachta seasmhach trasna daonraí, pointe agus cur chuige anailíse.
Comhoiriúnacht le torthaí diúltacha
An fadhb chúisíochta
Beagnach gach fianaise seo tá sí breathnaithe, agus tá iontógáil bia ultra-prosessed tangled le beagnach gach fachtóir sláinte eile — ioncam, oideachas, bochtaineacht ama, rochtain ar bhia, áiseanna cócaireachta, gníomhaíocht. Cuireann coigeartú staitistiúil laghdú ar chonfhadh; ní dhéanann sé é a dhíothú, go háirithe nuair a thomhaistear na comhoiriúnachtaí go garbh agus tomhaistear an nochtadh trí cheistneoir minicíocht bia.
Tagann an fianaise chúisíochta is láidre ó obair ithe rialaithe ina itheann daoine níos mó calraí agus faigheann siad meáchan ar aiste bia ultra-prosessed ná ar aiste bia neamhphróiseáilte comhoiriúnach, in ainneoin go bhfuil béilí comhoiriúnach do mhacronutrient agus calraí curtha i láthair. Sin staidéar beag laistigh — an-eolasach, agus staidéar amháin.
Na meicníochtaí plauisí
- Dlús fuinnimh. Níos mó calraí in aghaidh bite, agus tá méid na poróidí rialaithe níos mó ag toirt ná ag fuinneamh.
- Ráta ithe. Tá struchtúir bog, íseal snáithín á n-ithe níos tapúla, agus tá comharthaí sásachta ag moill ar iontógáil.
- Díothú snáithín. Tá aistí bia ultra-prosessed go ginearálta i bhfad níos ísle i snáithín.
- Hyper-palatability. Comhoibrithe áirithe saille-sugar-salt nach bhfuil le fáil go coitianta i mbia iomlán.
- Díothú. Is béile é gach béile ultra-prosessed nach bhfuil rud éigin eile.
Tabhair faoi deara go bhfuil na meicníochtaí seo go príomha ag ithe níos mó, a oireann don toradh ithe rialaithe agus a nascann an litríocht seo leis an gcomhoibriúnacht fuinnimh gnáth seachas é a chur in ionad.
Cad atá le déanamh leis seo
Maireann an comhairle phraicticiúil an neamhchinnteacht chúisíochta, toisc gurb é an comhairle chéanna a dhéanfá ar aon nós: níos mó bianna iomlána, níos mó snáithín, níos mó cócaireachta baile nuair a cheadaítear na cúinsí. Cad nach maireann ná an frámáil níos deacra — go bhfuil bia ultra-prosessed go hiomlán tocsaineach, nó go bhfuil táirge ar leith contúirteach mar gheall ar a chatagóir NOVA seachas a ábhar.
Tá sé tábhachtach freisin go bhfuil sé seo go mór ina fhadhb struchtúrach. Tá bia ultra-prosessed saor, seasmhach ar an seilf, ní theastaíonn aon trealamh agus aon am. Is comhairle é a sheachaint a chiallaíonn comhairle a chaitheamh airgead agus am nach bhfuil ag go leor daoine.
Ceisteanna coitianta
An bhfuil bia próiseáilte go léir dona?
An bhfuil arán siopa iomlán ultra-prosessed?
An gcuireann sé ailse?
An bhfuil orm bia próitéine agus cruthanna a sheachaint?
