Consuming fructose-sweetened, not glucose-sweetened, beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese humans

Studies in animals have documented that, compared with glucose, dietary fructose induces dyslipidemia and insulin resistance. To assess the relative effects of these dietary sugars during sustained consumption in humans, overweight and obese subjects consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks. Although both groups exhibited similar weight gain during the intervention, visceral adipose volume was significantly increased only in subjects consuming fructose. Fasting plasma triglyceride concentrations increased by approximately 10% during 10 weeks of glucose consumption but not after fructose consumption. In contrast, hepatic de novo lipogenesis (DNL) and the 23-hour postprandial triglyceride AUC were increased specifically during fructose consumption. Similarly, markers of altered lipid metabolism and lipoprotein remodeling, including fasting apoB, LDL, small dense LDL, oxidized LDL, and postprandial concentrations of remnant-like particle–triglyceride and –cholesterol significantly increased during fructose but not glucose consumption. In addition, fasting plasma glucose and insulin levels increased and insulin sensitivity decreased in subjects consuming fructose but not in those consuming glucose. These data suggest that dietary fructose specifically increases DNL, promotes dyslipidemia, decreases insulin sensitivity, and increases visceral adiposity in overweight/obese adults.

JOHTAVAT RAVITSEMUSTUTKIJAT VAATIVAT: D-VITAMIIIN SAANTISUOSITUKSET TULISI MÄÄRITTÄÄ TÄYSIN UUSIKSI - D-vitamiinin saantisuositukset - terveystaito.fi

"American Journal of Clinical Nutrition lehden (AJCN) tammikuun 2007 numerossa julkaistussa laajassa kokoomatutkimuksessa kritisoidaan voimakkaasti nykyisiä alhaisia D-vitamiinin saantisuosituksia (1). Lehden tutkimuksessa päivittäinen turvallinen annostus terveille ihmisille nostetaan aivan uudelle tasolle. Tällä hetkellä yleisesti hyväksyttynä turvallisena ylärajana pidetään 50 mikrogrammaa päivässä, tämän seurauksena Suomessakin nostettiin vuonna 2006 päivittäinen saantisuositus 7 mikrogrammasta 10 mikrogrammaan. Tiedeyhteisö on jo pitkään kritisoinut liian alhaisia D-vitamiinisuosituksia. Useimmat D-vitamiini-asiantuntijat ovat sitä mieltä, että 25(OH)D:n veripitoisuus tulisi olla vähintään 80 nmol/l, jotta D-vitamiinista saavutettaisiin optimaalinen hyöty. Viitearvoalue 25(OH)D:lle on Suomessa määritetty 10 - 105 nmol/l (tavoitetaso 40-80 nmol/l). Jotta 97.5 % väestöstä pääsisi 80 nmol/l tasolle tulisi D3-vitamiinin saanti olla vähintään 75 ug (3000 ky)/pv (2)."
