"We're less concerned about naturally occurring fructose in fruits, which also contain important antioxidants," explained Gomez-Pinilla, who is also a member of UCLA's Brain Research Institute and Brain Injury Research Center. "We're more concerned about the fructose in high-fructose corn syrup, which is added to manufactured food products as a sweetener and preservative."ogi je napisao/la:http://newsroom.ucla.edu/portal/ucla/this-is-your-brain-on-sugar-ucla-233992.aspx
http://ajcn.nutrition.org/content/early ... 112.057331The researchers discovered that over the six-week study period liver damage more than doubled in the animals which were fed a high-fructose diet in comparison to those in the control group. This study has been published online in the June 19 edition of the American Journal of Clinical Nutrition.
Kylie Kavanagh, D.V.M., lead author of the study, has said, “What surprised us the most was how quickly the liver was affected and how extensive the damage was, especially without weight gain as a factor." Fructose was studied because it is the most common sugar which is added in the American diet. However, it can not be said conclusively from this study that fructose caused the liver damage. There could be clinical implications to the finding that liver damage began even in the absence of weight gain, and so further studies are suggested.
Inulin je posebna vrsta škroba. Najrasprostranjeniji je u porodici glavočika jezičnjača. Pri razgradnji inulina enzimom inulazom nastaje fruktoza
The effects of consuming a diet high in fructose,compared to a diet high in glucose, on the rate of hepatic de novo lipogenesis (DNL) in overweightand obese individuals were studied. These subjects were given a diet in which either glucose or fructose was substituted for 25% of their energy requirements for 10 weeks. During the fasted state,subjects’ DNL for those on a glucose and fructose diet were similar. However, in the fed state, DNL was increased significantly in subjects given a fructose diet. This suggests that consuming a diet from fructose-sweetened beverages increases DNL
Vodi računa o tome da pod "fructose-sweetened beverages" oni govore o fruktozi dobivenoj iz kukuruznog škroba pomoću posebnih enzima. Coca-cola više ne koristi šećer nego "high fructose corn syrup". Potraži si više informacija u "Sugar - the Bitter truth" dokumentarcu. Pitanje je kakvi bi bili rezultati studije kad bi subjekti jeli voće bogato fruktozom.ogi je napisao/la:...This suggests that consuming a diet from fructose-sweetened beverages increases DNL...
Moram priznati da je moja filozofija drugačija. Pročitao sam na puno mjesta, a i uvjerio se sam jer sam gutao velike količine C vitamina i drugih umjetnih tvorevina iz te industrije, da isti spoj u svom prirodnom okruženju puno povoljnije utječe na ljudsko tijelo od onog koji je umjetno sintetiziran ili prerađen. Negdje sam čitao da jedna naranča koja ima 60 mg vitamina C jednako korisno djeluje na tijelo kao 1000 g vitamina C iz tablete - po pitanju C vitamina, naravno. A ne ostavlja nikakve dugoročne nuspojave, što se ne može reći za umjetni vitamin C. Tako da ne, ne slažem se s tobom. Nije to isto. Važno je i okruženje. Što je u tom voću pored fruktoze - to je ključno! Barem je moj dojam/razmišljanje/filozofija takav.ogi je napisao/la:Znam ali mislim da je fruktoza fruktoza bez obzira da li je unosimo kuhinjskim šećerom, colom, jabukama ili batatom
Kako onda objasniti slučajeve u kojima su se ljudi izlječili (ili stavili pod kontrolu) dijabetes nakon određenog perioda prehranjivanjem sirovom hranom, u čemu je naravno, bilo i ogromnih količina voća tj. voćnog šećera (fruktoze)?ogi je napisao/la:Upravu si da nije sve jedno iz kojeg je izvora u smislu zdrave prehrane ali u smislu unosa maksmalnih preporucenih 50g fruktoze dnevno mislim da je svejedno ili je mala razlika
