Mukuyesera kudya bwino. Mukuchita masewera olimbitsa thupi. Koma pazifukwa zina, kukula sikukutuluka, kapena kulemera sikubwera mwachangu momwe mungafunire."Vuto lochepa thupi ndilo vuto m'maselo anu amafuta," akutero katswiri wa sayansi ya zakudya ndi masewera olimbitsa thupi David Plourdé, Ph.D., yemwe anayambitsa The Plourdé Institute. M'dongosolo lake losakanikirana ndi sayansi, amathandizira anthu kuti azigwiritsa ntchito lipase yolondola lipase, ma enzyme omwe amawononga mafuta, kubwerera m'manja kuti maselo awo athe kuwononga mafuta ndikuwamasula, zomwe zimapangitsa kuti mafuta awonongeke m'thupi. "Koma chakudya chobisika chimalepheretsa izi mpaka masiku atatu," akutero.

Kodi ma carbohydrate obisika ndi chiyani? Ndiwo magwero a shuga ndi wowuma omwe amabisala mkati mwa zakudya za tsiku ndi tsiku (zomwe zimawoneka ngati zathanzi). Mwachitsanzo, taganizirani za broccoli-cheddar omelet: Zikumveka ngati chakudya chokhala ndi mapuloteni ambiri, sichoncho? Chabwino, ngati mutapanga omelet ndi tchizi wopangidwa kale, akhoza kuwonjezera pa cellulose (chomwe chimalepheretsa shreds kuti zisagwirizane). Ndipo mapadi opangidwa ndi ufa ndi wowuma. Ponena za mazira, ngati mutagwiritsa ntchito azungu omwe anali atapatulidwa kale, akhoza kusintha wowuma wa chakudya omwe amalembedwa ngati chogwiritsira ntchito. Ndipo kusinthidwa chakudya wowuma kwenikweni ufa. Mndandanda wa zitsanzo ukupitirirabe-izi zotsekemera za carb zikubisala mu nkhuku (yang'anani mawu oti "chinthu," ndi chidziwitso chakuti nkhuku imalimbikitsidwa ndi wowuma), zakumwa zina (ngakhale zakudya zowonjezera), komanso mankhwala. (Pezani njira zambiri zochotsera zinthu zokoma ndi Momwe Mungachepetsere Shuga.)

Ma carbs obisika awa amatha kukhudza kwambiri kulemera kwanu. Pomwe Dr. Plourdé adachita kafukufuku wa anthu 308 onenepa kwambiri, onse onenepa kwambiri, chakudya chamafuta ochepa, kudziwa zamahydro obisika ndikofunikira kwambiri pakuchepetsa thupi. Pakafukufuku wake, gulu limodzi silinapeze chitsogozo chopewa chakudya chobisika, gulu lachiwiri silinapeze zambiri, ndipo gulu lachitatu lidapatsidwa malangizo amomwe angapewere shuga wobisika ndi sitashi. Gulu lachitatu, lokhala ndi chidziwitso chatsatanetsatane, lidataya 67 peresenti yamafuta amthupi-pafupifupi 50% kuposa gulu lomwe silimadziwa chilichonse chokhudza ma carbs obisika.]

Ndiye mungapewe bwanji izi mobisa zobisika kuwonda saboteurs? Choyamba, yang'anani mawu ngati maltodextrin (opangidwa kuchokera ku wowuma), wowuma wosinthidwa, ndi mapadi a mapadi (opangidwa ndi ulusi wazomera). Koma lamulo labwino la chala chachikulu ndikusunga chakudya chanu kukhala chosavuta, ndikupewa zinthu zomwe zili ndi zowonjezera zingapo (ndi The Hottest New Food Trend: Real Food!). "Ngati mndandanda wa zosakaniza uli ndi ndime yaitali, simukusowa Ph.D. mu chemistry kuti tsopano mukupeza chakudya chobisika," akutero Dr. Plourdé.
