- dej cawv (sorbitol, xylitol);
- cov khoom qab zib (cyclamate, aspartame);
- fructose.
Cov carbohydrate kawg muaj cov ntsiab lus calorie ntawm 4 kcal / g. Cov neeg sawv cev ntawm thawj pab pawg yuav luag nyob hauv tib hom caloric - 3.4-3.7 kcal / g. Lawv qhov noj ntau npaum li 30 g tsis cuam tshuam txog qib glycemic ntawm cov ntshav hauv lub cev. Nws raug nquahu kom siv qhov tau tso cai siv li ob lossis peb koob.
Kev lwj ntawm txoj kab ntawm fructose yog luv dua nws qhov sib txig hauv pawg - qabzib. Nws nce glycemic theem 2-3 lub sij hawm qeeb dua li cov zaub mov qab zib. Raws li monosaccharide, nws muaj cov haujlwm hauv qab no:
Qab zib rau cov ntshav qab zib- lub zog
- kev teeb tsa
- tso rau
- pov thaiv.
Cov carbohydrates yog qhov tseem ceeb ntawm lub zog. Lawv nkag mus rau cov qauv hauv cov ntaub so ntswg tag nrho cov ntaub so ntswg, koom nrog qhov kev hloov pauv hauv lub cev. Cov tshuaj organic nyuaj muaj lub peev xwm los nthuav tawm hauv daim ntawv ntawm glycogen hauv daim siab txog 10%. Nws yog noj raws li qhov tsim nyog.
Thaum yoo mov, cov ntsiab lus glycogen tuaj yeem txo qis txog 0.2%. Carbohydrates thiab lawv qhov keeb kwm yog ib feem ntawm hnoos qeev (viscous zais ntawm ntau cov qog) uas tiv thaiv sab hauv ntawm cov nruab nrog cev. Vim tias cov roj ntsha ua rau lub cev, txoj hlab pas, plab, bronchi lossis hnyuv muaj kev tiv thaiv los ntawm kev kho tshuab thiab kev puas tsuaj rau cov kab mob phom sij, kab mob.
Thaum xaiv cov khoom lag luam ntshav qab zib, koj yuav tsum xub them sai sai rau hnub tas sij hawm thiab daim ntawv lo
