NCT02385149

Brief Summary

This study investigates the health benefits of whole grain wheat on cardiovascular/ cardio-metabolic health, including glucose metabolism, by means of applying a mixed meal challenge. This study also investigates the health benefits of whole grain wheat (WGW) on liver- and adipose tissue health and evaluates the potential of do-it-yourself (DIY) devices in quantifying health effects in a nutritional intervention study.

Outcome Measures

Primary Outcomes (1)

  • Change in cardio-metabolic health parameters (composite)

    parameters include change in cholesterol, TAG, glucose, insulin, FMD (Fasting only), pulse wave analysis (Fasting and 120, 240min postprandial), blood pressure(Fasting and 120, 240min postprandial), blood cell activation (Fasting only) and plasma markers of cardio-vascular health

    Baseline and after 12 week intervention (at 0 and 12 weeks) , during fasting and in response to a mixed meal challenge test (at 30,60,120,240 min postprandial)

Secondary Outcomes (4)

  • Change in liver-and adipose tissue health parameters (composite)

    Baseline and after 12 week intervention (at 0 and 12 weeks), during fasting and in response to a mixed meal challenge test (at 30,60,120,240 min postprandial)

  • Change in do-it-yourself measure outcomes (composite)

    At baseline and every two weeks during the intervention (at 0,2,4,6,8,10,12 weeks)

  • Change in health and mood questionaire outcomes

    At baseline and every two weeks during the intervention (at 0,2,4,6,8,10,12 weeks)

  • Change in blood markers of whole grain intake

    before and after 12 week intervention (at 0 and 12 weeks)

Other Outcomes (3)

  • Change in peripheral blood mononuclear cells

    Baseline and after 12 week intervention (at 0 and 12 weeks), during fasting and in response to a mixed meal challenge test (at 60 and 240 min postprandial)

  • Change in markers of satiety (composite)

    Baseline and after 12 week intervention (at 0 and 12 weeks, during fasting and in response to a mixed meal challenge test (at 10,30,60,120,240 min postprandial)

  • Urine and faecal collection

    Baseline and after 12 week intervention (at 0 and 12 weeks)
