  Purpose

The aim of the project is to investigate the effects of advanced glycation end products (AGEs) formed in food during the cooking process as well as AGEs formed naturally in the human body, on insulin sensitivity and risk factors for type 2 diabetes. The hypothesis is that i) food content of AGEs is lower using boiling and steaming cooking methods and that ii) AGEs formation in the body is lower at low dietary intake of certain sugar forms.

    insulin sensitivity

  • change in OGTT from baseline to 4 weeks [ Time Frame: 0 and 4 weeks at 0 and 120 min ] [ Designated as safety issue: No ]
    insulin sensitivity

  • change in appetite hormones (leptin, adiponectin, GLP-1, glukagon, ghrelin) from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
  • change in plasma and urin AGEs from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
  • change in immune response (CRP, C-peptide, IL-1B, IL-6, VCAM, ICAM, MIF, TNF-a, buffycoat) from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
  • change in metabolomics dats from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
  • change in AGE levels in skin from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • change in lipid profile (TG, Chol, LDL, HDL, ox LDL, glycated LDL, fattyacids)from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
  • change in HbA1c from baseline to 4 weeks [ Time Frame: 0 and 4 weeks ] [ Designated as safety issue: No ]
