Kutheni abantu bethenga iilekese? (Ibhokisi yeelekese)

 Iswekile, i-carbohydrate elula enika umzimba amandla ngokukhawuleza, ifumaneka kwiintlobo ngeentlobo zokutya neziselo esizityayo imihla ngemihla—ukusuka kwiziqhamo, imifuno kunye neemveliso zobisi, ukuya kwiilekese, iipastries kunye nezinye iidizethi.

Imibhiyozo efana noSuku lwePayi lweSizwe olusandula ukwamkelwa (ngoJanuwari 23) kunye noSuku lweCake yeChocolate yeSizwe (ngoJanuwari 27) isimema ukuba sizonwabise—kodwa yintoni ebangela ukuba sinqwenele ukutya okuneswekile?

 Ukuze siqonde ngcono imiphumo yeswekile emzimbeni nasengqondweni, iThe Daily ithethe noLindsay Malone, utitshala kwiSebe leZondlo kwiYunivesithi yaseCase Western Reserve.

1. Iincasa zisabela njani ngokukodwa kwiswekile emzimbeni? Zeziphi izinto ezibangela ukuba abantu bafune ukutya okuneswekile?

Une-taste receptors emlonyeni wakho nasemathunjini eziphendula kwiilekese. Ezi -taste receptors zidlulisela ulwazi ngee-sensory afferent fibers (okanye ii-nerve fibers) kwiindawo ezithile engqondweni ezibandakanyekayo ekuqondeni incasa. Kukho iintlobo ezine zeeseli ze-taste receptor cells zokufumanisa incasa emnandi, i-umami, ekrakra neyomuncu.

Ukutya okuvuselela inkqubo yomvuzo engqondweni yakho, njengeswekile kunye nokunye ukutya okunyusa iswekile egazini lakho, kunokubangela inkanuko. Ukutya okumnandi kakhulu (oko kumnandi, kunetyuwa, kukhrimu kwaye kulula ukukutya) kunokubangela iihomoni ezinegalelo kwinkanuko—ezifana ne-insulin, i-dopamine, i-ghrelin kunye ne-leptin.

2. Ingqondo idlala yiphi indima kulonwabo oluhambelana nokutya ukutya okunencasa, kwaye oku kunceda njani ekufuneni ukutya okuneswekile eninzi?(Ibhokisi yeelekese)

Inkqubo yakho yemithambo-luvo ephakathi inxulumene kakhulu nomgudu wakho wokugaya ukutya. Ezinye iiseli ze-taste receptor zikhona emathunjini akho, ngoko ke xa usitya ukutya okumnandi kwaye iswekile egazini inyuka ingqondo yakho ithi: “Oku kulungile, ndiyakuthanda oku. Qhubeka usenza oku.”

Sidalwe ngendlela yokuba sifune amandla akhawulezileyo xa kukho indlala okanye sidinga amandla ongezelelweyo ukuze sibaleke kwisakhiwo esitshayo okanye ingwe. Izakhi zethu zemfuza azikaphuhli ngokukhawuleza njengendawo esikuyo. Sikwadibanisa nokutya okwandisa iminqweno. Cinga ngedonathi nekofu yakho yasekuseni. Ukuba le ngumkhwa wakho wesiqhelo, akumangalisi ukuba ubuya kufuna idonathi rhoqo xa usela ikofu. Ingqondo yakho iyayibona ikofu ize iqale ukuzibuza ukuba iphi idonathi.

3. Ziziphi ezinye zeenzuzo kunye neengozi ezinokubakho zokusebenzisa iswekile?(Ibhokisi yeelekese)

Iswekile inokuba luncedo kwimidlalo, ekuzilolongeni, kwiimbaleki njl. Ngaphambi komsitho, ekuzilolongeni okanye kukhuphiswano, imithombo yeswekile ekulula ukuyicola inokuba luncedo. Iya kubonelela ngamandla ngokukhawuleza kwizihlunu ngaphandle kokucothisa ukugaywa. Ubusi, isiraphu ye-maple ecocekileyo, iziqhamo ezomisiweyo, kunye neziqhamo ezingenafayibha eninzi (ezifana neebhanana kunye neediliya) zinokunceda koku.

Iingxaki ezinxulumene nokutya iswekile ziyanda ngenxa yokungazilolongi. Iswekile egqithisileyo, iiswekile ezongeziweyo kunye nezinye iicarbohydrate ezilula ezifana nomgubo omhlophe kunye nejusi eyi-100% zinxulunyaniswa nokubola kwamazinyo, isifo se-metabolic syndrome, ukudumba, i-hyperglycemia (okanye iswekile ephezulu yegazi), isifo seswekile, ukunganyangeki kwe-insulin, ukutyeba kakhulu, ukutyeba kakhulu, isifo sentliziyo, kwanesifo sika-Alzheimer. Ngamanye amaxesha, ubudlelwane buyimbangela; ngamanye amaxesha, yinxalenye enye yeqela lezinto ezikhokelela kwisifo.

4. Singalwakha njani ulwalamano olusempilweni nokutya okunencasa ngokutya ngengqondo?(Ibhokisi yeelekese)

Amanye amacebiso aquka ukutya kancinci, ukuhlafuna kakuhle kunye nokunandipha ukutya kwethu. Kubalulekile nokuba sibandakanyeke ekutyeni kwethu nangona kunokwenzeka—nokuba kukwenza igadi, ukucwangcisa ukutya, ukuthenga okanye ukupheka nokubhaka. Ukuzenzela ukutya kwethu kusenza silawule iswekile esiyityayo.

5. Ngokuphathelele ukulinganisela, yintoni esinokuyenza ukuze silawule ngcono ukunqwenela iswekile?(Ibhokisi yeelekese)

Kukho amaqhinga amane endiwacebisayo okunciphisa ukuxhomekeka kwiswekile:

 Yitya ukutya okupheleleyo, okungaxutywanga kakhulu. Umthamo, ifayibha kunye neproteni kunokunceda ekunciphiseni ukunyuka kwe-insulin kunye nokunqwenela ukutya.

Susa iswekile eyongeziweyo. Yeka ukongeza iswekile, isiraphu, izithambisi zokwenziwa ekutyeni. Funda iilebheli kwaye ukhethe iimveliso ezingenaswekile eyongeziweyo. Ezi zihlala ziquka iziselo, ikhrimu yekofu, isosi yespaghetti kunye nezinongo.

Sela iziselo ezingenaswekile kakhulu ezifana namanzi, i-seltzer, iti yemifuno kunye nekofu.

Hlala usebenza kwaye ugcine ukwakheka komzimba okuhle, njengamafutha omzimba kunye nobunzima bemisipha kwindawo enempilo. Izihlunu zisebenzisa iswekile yegazi ejikelezayo kwaye zinceda ekulweni nokuxhathisa i-insulin. Isiphumo sokugqibela kukuba iswekile yegazi ilawulwe ngcono ngokuncipha nokuncipha.
