0:00:06.825,0:00:09.101
Imagjinoni disa biskota te ngrohta e te lengshme,

0:00:09.101,0:00:10.513
karamele krokante,

0:00:10.513,0:00:12.076
keke te mendafshte,

0:00:12.076,0:00:14.693
kone prej vaferi te tejmbushur me akullore.

0:00:14.693,0:00:16.670
A po ju leshon goja leng?

0:00:16.670,0:00:17.538
Ju vjen deshira per embelsira?

0:00:17.538,0:00:18.843
Pse?

0:00:18.843,0:00:19.924
Cfare ndodh ne trurin tone

0:00:19.924,0:00:23.700
qe i ben kaq te parrezistueshme ushqimet e embla?

0:00:23.700,0:00:24.421
Fjala sheqer eshte nje term i pergjithshem

0:00:24.421,0:00:26.549
qe perdoret per te pershkruar nje categori molekulash

0:00:26.549,0:00:28.427
te quajtura karbohidrate,

0:00:28.427,0:00:31.278
dhe gjendet ne nje game te gjere ushqimesh dhe pijesh.

0:00:31.278,0:00:34.212
Mjafton te kontrolloni etiketat e embelsirave qe blini.

0:00:34.212,0:00:34.913
Glukosa,

0:00:34.913,0:00:35.695
fruktoza,

0:00:35.695,0:00:36.627
sukroza,

0:00:36.627,0:00:37.495
maltoza,

0:00:37.495,0:00:38.295
laktozi,

0:00:38.295,0:00:38.969
dekstroza,

0:00:38.969,0:00:39.681
dhe niseshteja

0:00:39.681,0:00:41.445
jane te gjitha forma sheqernash.

0:00:41.445,0:00:43.525
Sic jane edhe shurupi i mistrit me nivel te larte fruktoze,

0:00:43.525,0:00:44.309
lengjet e frutave,

0:00:44.309,0:00:45.294
sheqeri

0:00:45.294,0:00:46.521
apo mjalti.

0:00:46.521,0:00:49.073
Dhe sheqeri nuk gjendet vetem tek karamelet e embelsirat,

0:00:49.073,0:00:51.188
ai i shtohet edhe salces se domateve,

0:00:51.188,0:00:51.846
kosit,

0:00:51.846,0:00:52.777
frutave te thata,

0:00:52.777,0:00:53.856
ujerave te aromatizuara,

0:00:53.856,0:00:55.700
apo shufrave me mysli.

0:00:55.700,0:00:56.603
Duke qene se sheqeri ndodhet gjithandej,

0:00:56.603,0:00:58.026
eshte e rendesishme te kuptojme

0:00:58.026,0:00:59.906
se c'ndikim ka ai tek truri.

0:00:59.906,0:01:02.275
Cfare ndodh kur sheqeri prek gjuhen tone?

0:01:02.275,0:01:03.528
A eshte e vertete se po te hash pak sheqer

0:01:03.528,0:01:05.480
deshiron edhe me shume?

0:01:05.480,0:01:07.025
Kafshon nje shufer grunjerash.

0:01:07.025,0:01:08.276
Sheqeri qe ajo permban

0:01:08.276,0:01:10.528
aktivizon receptoret e shijet

0:01:10.528,0:01:12.770
qe ndodhen ne gjuhe.

0:01:12.770,0:01:15.771
Keta receptore dergojne nje sinjal ne trungun e trurit,

0:01:15.771,0:01:17.375
dhe nga aty, sinjali shperndahet

0:01:17.375,0:01:19.261
ne zona te ndryshme te trurit,

0:01:19.261,0:01:21.813
njera prej te cilave eshte korteksi.

0:01:21.813,0:01:23.964
Zona te ndryshme te kortekstit

0:01:23.964,0:01:25.864
perpunojne shije te ndryshme:

0:01:25.864,0:01:26.399
te hidhuren,

0:01:26.399,0:01:26.985
te kripuren,

0:01:26.985,0:01:27.711
umamin,

0:01:27.711,0:01:29.823
dhe ne rastin tone, te emblen.

0:01:29.823,0:01:31.328
Prej ketej sinjali aktivizon

0:01:31.328,0:01:33.440
sistemin shperblyes te trurit.

0:01:33.440,0:01:34.909
Ky sistem shperblyes perbehet nga nje sere

0:01:34.909,0:01:37.125
ngacmimesh elektrike dhe kimike

0:01:37.125,0:01:39.749
te zonave te ndryshme te trurit.

0:01:39.749,0:01:40.873
Eshte nje rrjet i nderlikuar,

0:01:40.873,0:01:44.171
por ai ndihmon ne gjetjen e pergjigjes [br]per te vetmen pyetje te pandergjegjshme:

0:01:44.171,0:01:45.877
a duhet te vazhdoj?

0:01:45.877,0:01:47.413
Ajo ndjesia e ngrohte, marramendese qe ke

0:01:47.413,0:01:49.501
kur provon kekun me cokollate te gjyshes?

0:01:49.501,0:01:51.295
Eshte sistemi i shperblimit qe te thote,

0:01:51.295,0:01:52.753
"Hmm, po! "

0:01:52.753,0:01:55.090
Ai nuk aktivizohet vetem nga ushqimi.

0:01:55.090,0:01:55.935
Shoqerizimi,

0:01:55.935,0:01:56.795
sjellja seksuale

0:01:56.795,0:01:57.469
dhe drogat

0:01:57.469,0:01:58.931
jane vetem pak nga shembujt

0:01:58.931,0:02:00.346
te gjerave apo pervojave

0:02:00.346,0:02:02.959
qe aktivizojne sistemin e shperblimit.

0:02:02.959,0:02:05.145
Por kur ky sistem aktivizohet se tepermi

0:02:05.145,0:02:08.435
atehere nisin nje sere ngjarjesh te papelqyeshme:

0:02:08.435,0:02:09.268
humbje kontrolli,

0:02:09.268,0:02:10.199
uri,

0:02:10.199,0:02:12.711
dhe tolerance e tepruar ndaj sheqernave.

0:02:12.711,0:02:14.963
Le te kthehemi tek kafshata jone e grunjerave.

0:02:14.963,0:02:17.069
Ajo udheton poshte drejt stomakut,

0:02:17.069,0:02:18.912
dhe pastaj drejt zorreve.

0:02:18.912,0:02:19.949
Dhe a e di?

0:02:19.949,0:02:22.380
Ketu ndodhen receptore te tjere te sheqernave.

0:02:22.380,0:02:23.335
Nuk dallojne shijen,

0:02:23.335,0:02:24.755
por ama dergojne sinjale

0:02:24.755,0:02:26.587
qe i thone trurit tend se je i ngopur

0:02:26.587,0:02:28.709
apo se trupi duhet te prodhoje me shume insuline

0:02:28.709,0:02:31.003
per te perballuar sheqerin e tepert qe ti po ha.

0:02:31.003,0:02:32.428
Monedha kryesore

0:02:32.428,0:02:34.563
e sistemit tone te shperblimit eshte dopamina,

0:02:34.563,0:02:37.153
nje neurotransmetues i rendesishem kimik.

0:02:37.153,0:02:39.684
Ne pjesen e perparme te trurit ka shume receptore dopamine,

0:02:39.684,0:02:41.840
por ata nuk jane te shperndare njetrajtesisht.

0:02:41.840,0:02:44.648
Ne disa zona gjenden ishuj te dendur receptoresh,

0:02:44.648,0:02:46.312
dhe keto pika te nxehta

0:02:46.312,0:02:48.481
jane pjese e sistemit te shperblimit.

0:02:48.481,0:02:49.767
Drogat si alkooli,

0:02:49.767,0:02:50.436
nikotina,

0:02:50.436,0:02:51.361
apo heroina

0:02:51.361,0:02:53.366
e cojne ne qiell nivelin e dopamines,

0:02:53.366,0:02:56.449
gje qe i nxit disa njerez te arrijne gjithnje ate nivel te larte,

0:02:56.449,0:02:58.645
e thene ndryshe, te krijojne varesi.

0:02:58.645,0:03:01.071
Edhe sheqeri nxit prodhimin e dopamines,

0:03:01.071,0:03:03.238
por jo ne nivele aq te larta sa drogat.

0:03:03.238,0:03:06.400
Dhe sheqeri eshte nje nga ushqimet e rralla [br]qe nxisin prodhimin e dopamines.

0:03:06.400,0:03:08.652
Per shembull, brokoli nuk ka asnje efekt,

0:03:08.652,0:03:09.738
gje qe ndoshta shpjegon se pse

0:03:09.738,0:03:12.837
eshte kaq e veshtire [br]t'i bindesh femijet te hane perime.

0:03:12.837,0:03:14.416
Teksa flasim per ushqimet e shendetshme,

0:03:14.416,0:03:15.620
supozojme se ti ke uri

0:03:15.620,0:03:17.597
dhe vendos te hash nje vakt te balancuar.

0:03:17.597,0:03:19.683
Ti e ben kete, keshtu dopamina ngacmon

0:03:19.683,0:03:21.349
ishujt e ndjeshem te sistemit te shperblimit.

0:03:21.349,0:03:24.730
Por nese ti ha po te njejtin ushqim per disa dite rresht,

0:03:24.730,0:03:27.063
niveli i dopamines do te ulet gjithnje e me shume,

0:03:27.063,0:03:28.998
derisa te arrije ne zero.

0:03:28.998,0:03:30.643
Kjo ndodh sepse, kur flitet per ushqime,

0:03:30.643,0:03:33.077
gjate evolucionit truri u mesua [br]t'i kushtonte vemendje te vecante

0:03:33.077,0:03:34.955
shijeve te reja ose te ndryshme.

0:03:34.955,0:03:35.900
Pse?

0:03:35.900,0:03:37.070
Ka dy arsye:

0:03:37.070,0:03:39.444
e para, per te kuptuar nese ushqimi ishte apo jo i prishur.

0:03:39.444,0:03:41.731
e dyta, sepse sa me shume varietet

0:03:41.731,0:03:42.753
te kemi ne dieten tone,

0:03:42.753,0:03:43.840
aq me e lehte do te jete

0:03:43.840,0:03:45.876
qe te marrim gjithe lendet qe na duhen.

0:03:45.876,0:03:47.251
Ne menyre qe t'a mbajme te gjalle kete varietet,

0:03:47.251,0:03:49.663
duhet te jemi ne gjendje te dallojme nje ushqim te ri,

0:03:49.663,0:03:50.839
dhe c'ka eshte me e rendesishme,

0:03:50.839,0:03:53.544
duhet te kemi gjithnje deshiren [br]per te ngrene ushqime te reja.

0:03:53.544,0:03:55.505
Ja pse niveli i dopamines bie

0:03:55.505,0:03:57.367
kur ushqimi behet i merzitshem.

0:03:57.367,0:03:58.966
Tani le te kthehemi tek vakti jone.

0:03:58.966,0:04:00.423
Cfare ndodh nese ne vend

0:04:00.423,0:04:02.092
te atij vakti te shendetshem e te balancuar,

0:04:02.092,0:04:04.307
ti vendos te hash ushqime [br]me permbajtje te larte sheqeri?

0:04:04.307,0:04:05.840
Nese e ha rralle sheqerin

0:04:05.840,0:04:07.339
ose nuk ha shume prej tij pernjeheresh,

0:04:07.339,0:04:09.973
efekti do te jete i njejte me ate [br]te nje vakti te balancuar.

0:04:09.973,0:04:11.174
Nese ha shume,

0:04:11.174,0:04:13.726
atehere niveli i dopamines nuk do te bjere.

0:04:13.726,0:04:15.493
E thene ndryshe, nese ha shume sheqerna

0:04:15.493,0:04:17.745
do te ndihesh gjithnje i shperblyer.

0:04:17.745,0:04:21.153
Ne kete drejtim, sheqeri sillet paksa si drogat.

0:04:21.153,0:04:22.933
Kjo eshte nje prej arsyeve [br]perse njerezit krijojne varesi

0:04:22.933,0:04:24.621
ndaj ushqimeve te embla.

0:04:24.621,0:04:27.267
Tani, kujtoni te gjitha llojet e ndryshme te sheqerit.

0:04:27.267,0:04:28.740
Secili prej tyre eshte unik,

0:04:28.740,0:04:30.928
por sa here qe njeri prej tyre hyn ne sistemin tone,

0:04:30.928,0:04:33.382
ai nxit nje efekt domino ne trurin tone

0:04:33.382,0:04:35.289
qe prodhon nje ndjesi shperblimi.

0:04:35.289,0:04:36.544
Eshte e forte, dhe ndodh shpesh,

0:04:36.544,0:04:38.720
prandaj ndodh edhe qe te kalohet limiti.

0:04:38.720,0:04:40.922
Pra, konsumi i tepert i sheqernave,

0:04:40.922,0:04:42.975
mund te krijoje varesi te trurit,

0:04:42.975,0:04:46.178
por nje copez kek nje here ne kaq [br]nuk do t'ju sjelle asnje te keqe.
