Brief Summary:
The aim of this study was to compare the metabolic effects of consuming whole barley bread and whole wheat bread, in healthy subjects. Also, to investigate the effect of whole grain flour on mineral status.

Condition or disease Intervention/treatment Phase
Metabolic Syndrome Other: Barley bread Other: Wheat bread Not Applicable

Detailed Description:

Generally, diet can be improved in order to lower diet-related diseases risk. However, the increasing prevalence rates of diet-related diseases indicate that, in practice, people's diet does not follow the recommendations. The intake of whole flour foods is consistently associated with reduced risk of type 2 diabetes and cardiovascular diseases in epidemiological studies, although the mechanisms of this association are unclear. Here the aim is to compare the metabolic effects and mineral status of consumption of diet containing wholemeal barley bread versus whole meal wheat bread in healthy subjects.

The intervention was designed as a randomized, cross over trial of 3-weeks duration. A total of 14 participants was included in the study. In one period subjects received WBB bread; in the second period, subjects received WWB bread. This bread is based on the recipe of Egyptian Baladi bread but formed in Danish buns form. Participants incorporated this bread into their normal habitual diet with regard to the study restrictions about other cereal food products. At the beginning and end of each intervention period blood was drawn and urine collected and stored for later analysis.

The primary outcomes of this study are evaluation of LDL-c, insulin and glucose levels evaluated by analysis of fasting blood samples. Furthermore, selected measures to evaluate SCFA level in blood is to be evaluated. Secondary outcomes include mineral status.

Primary Outcome Measures :
  1. LDL-c levels evaluated by analysis of fasting blood samples [ Time Frame: 8-9 weeks ]
    Evaluated by analysis of fasting blood samples

  2. Glucose levels evaluated by analysis of fasting blood samples [ Time Frame: 8-9 weeks ]
    Evaluated by analysis of fasting blood samples

  3. Insulin levels evaluated by analysis of fasting blood samples [ Time Frame: 8-9 weeks ]
    Evaluated by analysis of fasting blood samples


Secondary Outcome Measures :
  1. Mineral status [ Time Frame: 8-9 weeks ]
    Evaluation depends on the mineral. Either by Atom absorption, ICP-MS or spectrometry
