00:00:06.825 --> 00:00:09.101
Imagjinoni disa biskota te ngrohta e te lengshme,

00:00:09.101 --> 00:00:10.513
karamele krokante,

00:00:10.513 --> 00:00:12.076
keke te mendafshte,

00:00:12.076 --> 00:00:14.693
kone prej vaferi te tejmbushur me akullore.

00:00:14.693 --> 00:00:16.670
A po ju leshon goja leng?

00:00:16.670 --> 00:00:17.538
Ju vjen deshira per embelsira?

00:00:17.538 --> 00:00:18.843
Pse?

00:00:18.843 --> 00:00:19.924
Cfare ndodh ne trurin tone

00:00:19.924 --> 00:00:23.700
qe i ben kaq te parrezistueshme ushqimet e embla?

00:00:23.700 --> 00:00:24.421
Fjala sheqer eshte nje term i pergjithshem

00:00:24.421 --> 00:00:26.549
qe perdoret per te pershkruar nje categori molekulash

00:00:26.549 --> 00:00:28.427
te quajtura karbohidrate,

00:00:28.427 --> 00:00:31.278
dhe gjendet ne nje game te gjere ushqimesh dhe pijesh.

00:00:31.278 --> 00:00:34.212
Mjafton te kontrolloni etiketat e embelsirave qe blini.

00:00:34.212 --> 00:00:34.913
Glukosa,

00:00:34.913 --> 00:00:35.695
fruktoza,

00:00:35.695 --> 00:00:36.627
sukroza,

00:00:36.627 --> 00:00:37.495
maltoza,

00:00:37.495 --> 00:00:38.295
laktozi,

00:00:38.295 --> 00:00:38.969
dekstroza,

00:00:38.969 --> 00:00:39.681
dhe niseshteja

00:00:39.681 --> 00:00:41.445
jane te gjitha forma sheqernash.

00:00:41.445 --> 00:00:43.525
Sic jane edhe shurupi i mistrit me nivel te larte fruktoze,

00:00:43.525 --> 00:00:44.309
lengjet e frutave,

00:00:44.309 --> 00:00:45.294
sheqeri

00:00:45.294 --> 00:00:46.521
apo mjalti.

00:00:46.521 --> 00:00:49.073
Dhe sheqeri nuk gjendet vetem tek karamelet e embelsirat,

00:00:49.073 --> 00:00:51.188
ai i shtohet edhe salces se domateve,

00:00:51.188 --> 00:00:51.846
kosit,

00:00:51.846 --> 00:00:52.777
frutave te thata,

00:00:52.777 --> 00:00:53.856
ujerave te aromatizuara,

00:00:53.856 --> 00:00:55.700
apo shufrave me mysli.

00:00:55.700 --> 00:00:56.603
Duke qene se sheqeri ndodhet gjithandej,

00:00:56.603 --> 00:00:58.026
eshte e rendesishme te kuptojme

00:00:58.026 --> 00:00:59.906
se c'ndikim ka ai tek truri.

00:00:59.906 --> 00:01:02.275
Cfare ndodh kur sheqeri prek gjuhen tone?

00:01:02.275 --> 00:01:03.528
A eshte e vertete se po te hash pak sheqer

00:01:03.528 --> 00:01:05.480
deshiron edhe me shume?

00:01:05.480 --> 00:01:07.025
Kafshon nje shufer grunjerash.

00:01:07.025 --> 00:01:08.276
Sheqeri qe ajo permban

00:01:08.276 --> 00:01:10.528
aktivizon receptoret e shijet

00:01:10.528 --> 00:01:12.770
qe ndodhen ne gjuhe.

00:01:12.770 --> 00:01:15.771
Keta receptore dergojne nje sinjal ne trungun e trurit,

00:01:15.771 --> 00:01:17.375
dhe nga aty, sinjali shperndahet

00:01:17.375 --> 00:01:19.261
ne zona te ndryshme te trurit,

00:01:19.261 --> 00:01:21.813
njera prej te cilave eshte korteksi.

00:01:21.813 --> 00:01:23.964
Zona te ndryshme te kortekstit

00:01:23.964 --> 00:01:25.864
perpunojne shije te ndryshme:

00:01:25.864 --> 00:01:26.399
te hidhuren,

00:01:26.399 --> 00:01:26.985
te kripuren,

00:01:26.985 --> 00:01:27.711
umamin,

00:01:27.711 --> 00:01:29.823
dhe ne rastin tone, te emblen.

00:01:29.823 --> 00:01:31.328
Prej ketej sinjali aktivizon

00:01:31.328 --> 00:01:33.440
sistemin shperblyes te trurit.

00:01:33.440 --> 00:01:34.909
Ky sistem shperblyes perbehet nga nje sere

00:01:34.909 --> 00:01:37.125
ngacmimesh elektrike dhe kimike

00:01:37.125 --> 00:01:39.749
te zonave te ndryshme te trurit.

00:01:39.749 --> 00:01:40.873
Eshte nje rrjet i nderlikuar,

00:01:40.873 --> 00:01:44.171
por ai ndihmon ne gjetjen e pergjigjes 
per te vetmen pyetje te pandergjegjshme:

00:01:44.171 --> 00:01:45.877
a duhet te vazhdoj?

00:01:45.877 --> 00:01:47.413
Ajo ndjesia e ngrohte, marramendese qe ke

00:01:47.413 --> 00:01:49.501
kur provon kekun me cokollate te gjyshes?

00:01:49.501 --> 00:01:51.295
Eshte sistemi i shperblimit qe te thote,

00:01:51.295 --> 00:01:52.753
"Hmm, po! "

00:01:52.753 --> 00:01:55.090
Ai nuk aktivizohet vetem nga ushqimi.

00:01:55.090 --> 00:01:55.935
Shoqerizimi,

00:01:55.935 --> 00:01:56.795
sjellja seksuale

00:01:56.795 --> 00:01:57.469
dhe drogat

00:01:57.469 --> 00:01:58.931
jane vetem pak nga shembujt

00:01:58.931 --> 00:02:00.346
te gjerave apo pervojave

00:02:00.346 --> 00:02:02.959
qe aktivizojne sistemin e shperblimit.

00:02:02.959 --> 00:02:05.145
Por kur ky sistem aktivizohet se tepermi

00:02:05.145 --> 00:02:08.435
atehere nisin nje sere ngjarjesh te papelqyeshme:

00:02:08.435 --> 00:02:09.268
humbje kontrolli,

00:02:09.268 --> 00:02:10.199
uri,

00:02:10.199 --> 00:02:12.711
dhe tolerance e tepruar ndaj sheqernave.

00:02:12.711 --> 00:02:14.963
Le te kthehemi tek kafshata jone e grunjerave.

00:02:14.963 --> 00:02:17.069
Ajo udheton poshte drejt stomakut,

00:02:17.069 --> 00:02:18.912
dhe pastaj drejt zorreve.

00:02:18.912 --> 00:02:19.949
Dhe a e di?

00:02:19.949 --> 00:02:22.380
Ketu ndodhen receptore te tjere te sheqernave.

00:02:22.380 --> 00:02:23.335
Nuk dallojne shijen,

00:02:23.335 --> 00:02:24.755
por ama dergojne sinjale

00:02:24.755 --> 00:02:26.587
qe i thone trurit tend se je i ngopur

00:02:26.587 --> 00:02:28.709
apo se trupi duhet te prodhoje me shume insuline

00:02:28.709 --> 00:02:31.003
per te perballuar sheqerin e tepert qe ti po ha.

00:02:31.003 --> 00:02:32.428
Monedha kryesore

00:02:32.428 --> 00:02:34.563
e sistemit tone te shperblimit eshte dopamina,

00:02:34.563 --> 00:02:37.153
nje neurotransmetues i rendesishem kimik.

00:02:37.153 --> 00:02:39.684
Ne pjesen e perparme te trurit ka shume receptore dopamine,

00:02:39.684 --> 00:02:41.840
por ata nuk jane te shperndare njetrajtesisht.

00:02:41.840 --> 00:02:44.648
Ne disa zona gjenden ishuj te dendur receptoresh,

00:02:44.648 --> 00:02:46.312
dhe keto pika te nxehta

00:02:46.312 --> 00:02:48.481
jane pjese e sistemit te shperblimit.

00:02:48.481 --> 00:02:49.767
Drogat si alkooli,

00:02:49.767 --> 00:02:50.436
nikotina,

00:02:50.436 --> 00:02:51.361
apo heroina

00:02:51.361 --> 00:02:53.366
e cojne ne qiell nivelin e dopamines,

00:02:53.366 --> 00:02:56.449
gje qe i nxit disa njerez te arrijne gjithnje ate nivel te larte,

00:02:56.449 --> 00:02:58.645
e thene ndryshe, te krijojne varesi.

00:02:58.645 --> 00:03:01.071
Edhe sheqeri nxit prodhimin e dopamines,

00:03:01.071 --> 00:03:03.238
por jo ne nivele aq te larta sa drogat.

00:03:03.238 --> 00:03:06.400
Dhe sheqeri eshte nje nga ushqimet e rralla 
qe nxisin prodhimin e dopamines.

00:03:06.400 --> 00:03:08.652
Per shembull, brokoli nuk ka asnje efekt,

00:03:08.652 --> 00:03:09.738
gje qe ndoshta shpjegon se pse

00:03:09.738 --> 00:03:12.837
eshte kaq e veshtire 
t'i bindesh femijet te hane perime.

00:03:12.837 --> 00:03:14.416
Teksa flasim per ushqimet e shendetshme,

00:03:14.416 --> 00:03:15.620
supozojme se ti ke uri

00:03:15.620 --> 00:03:17.597
dhe vendos te hash nje vakt te balancuar.

00:03:17.597 --> 00:03:19.683
Ti e ben kete, keshtu dopamina ngacmon

00:03:19.683 --> 00:03:21.349
ishujt e ndjeshem te sistemit te shperblimit.

00:03:21.349 --> 00:03:24.730
Por nese ti ha po te njejtin ushqim per disa dite rresht,

00:03:24.730 --> 00:03:27.063
niveli i dopamines do te ulet gjithnje e me shume,

00:03:27.063 --> 00:03:28.998
derisa te arrije ne zero.

00:03:28.998 --> 00:03:30.643
Kjo ndodh sepse, kur flitet per ushqime,

00:03:30.643 --> 00:03:33.077
gjate evolucionit truri u mesua 
t'i kushtonte vemendje te vecante

00:03:33.077 --> 00:03:34.955
shijeve te reja ose te ndryshme.

00:03:34.955 --> 00:03:35.900
Pse?

00:03:35.900 --> 00:03:37.070
Ka dy arsye:

00:03:37.070 --> 00:03:39.444
e para, per te kuptuar nese ushqimi ishte apo jo i prishur.

00:03:39.444 --> 00:03:41.731
e dyta, sepse sa me shume varietet

00:03:41.731 --> 00:03:42.753
te kemi ne dieten tone,

00:03:42.753 --> 00:03:43.840
aq me e lehte do te jete

00:03:43.840 --> 00:03:45.876
qe te marrim gjithe lendet qe na duhen.

00:03:45.876 --> 00:03:47.251
Ne menyre qe t'a mbajme te gjalle kete varietet,

00:03:47.251 --> 00:03:49.663
duhet te jemi ne gjendje te dallojme nje ushqim te ri,

00:03:49.663 --> 00:03:50.839
dhe c'ka eshte me e rendesishme,

00:03:50.839 --> 00:03:53.544
duhet te kemi gjithnje deshiren 
per te ngrene ushqime te reja.

00:03:53.544 --> 00:03:55.505
Ja pse niveli i dopamines bie

00:03:55.505 --> 00:03:57.367
kur ushqimi behet i merzitshem.

00:03:57.367 --> 00:03:58.966
Tani le te kthehemi tek vakti jone.

00:03:58.966 --> 00:04:00.423
Cfare ndodh nese ne vend

00:04:00.423 --> 00:04:02.092
te atij vakti te shendetshem e te balancuar,

00:04:02.092 --> 00:04:04.307
ti vendos te hash ushqime 
me permbajtje te larte sheqeri?

00:04:04.307 --> 00:04:05.840
Nese e ha rralle sheqerin

00:04:05.840 --> 00:04:07.339
ose nuk ha shume prej tij pernjeheresh,

00:04:07.339 --> 00:04:09.973
efekti do te jete i njejte me ate 
te nje vakti te balancuar.

00:04:09.973 --> 00:04:11.174
Nese ha shume,

00:04:11.174 --> 00:04:13.726
atehere niveli i dopamines nuk do te bjere.

00:04:13.726 --> 00:04:15.493
E thene ndryshe, nese ha shume sheqerna

00:04:15.493 --> 00:04:17.745
do te ndihesh gjithnje i shperblyer.

00:04:17.745 --> 00:04:21.153
Ne kete drejtim, sheqeri sillet paksa si drogat.

00:04:21.153 --> 00:04:22.933
Kjo eshte nje prej arsyeve 
perse njerezit krijojne varesi

00:04:22.933 --> 00:04:24.621
ndaj ushqimeve te embla.

00:04:24.621 --> 00:04:27.267
Tani, kujtoni te gjitha llojet e ndryshme te sheqerit.

00:04:27.267 --> 00:04:28.740
Secili prej tyre eshte unik,

00:04:28.740 --> 00:04:30.928
por sa here qe njeri prej tyre hyn ne sistemin tone,

00:04:30.928 --> 00:04:33.382
ai nxit nje efekt domino ne trurin tone

00:04:33.382 --> 00:04:35.289
qe prodhon nje ndjesi shperblimi.

00:04:35.289 --> 00:04:36.544
Eshte e forte, dhe ndodh shpesh,

00:04:36.544 --> 00:04:38.720
prandaj ndodh edhe qe te kalohet limiti.

00:04:38.720 --> 00:04:40.922
Pra, konsumi i tepert i sheqernave,

00:04:40.922 --> 00:04:42.975
mund te krijoje varesi te trurit,

00:04:42.975 --> 00:04:46.178
por nje copez kek nje here ne kaq 
nuk do t'ju sjelle asnje te keqe.
