A diet with the multiple beneficial characteristics of whole grains and, more in general, of "healthy cereals" favorably influences glucose and insulin metabolism in subjects with metabolic syndrome. Therefore, the aim of the study is to evaluate the long term effects of a diet containing "healthy cereals" versus a control diet, on glucose and insulin metabolism in subjects with metabolic syndrome.

| Wholegrain cereal diet | Other | Thirty subjects with metabolic syndrome, after an initial run-in period of 4 weeks, during which they stabilise their own diet and other lifestyle habits, are assigned to a diet based on wholegrain cereals and foods with low glycemic index for a period of 12 weeks. Before and after the dietary treatment, a frequently samples intravenous glucose tolerance is carried out to measure the effects of the intervention on glucose and insulin metabolism. At beginning and at the end of intervention, the subjects consume also a standard test meal to evaluate the postprandial response of glucose, insulin, lipids, oxidative parameters and inflammatory molecules. |
| Measure | Description | Time Frame |
|---|---|---|
| Insulin Sensitivity (Si) | Peripheral insulin sensitivity was assessed by FSIGT. A glucose dose of 300 mg/kg body weight was given intravenously followed by a bolus of 0.03 U/kg of insulin injected after 20 min. Blood samples were frequently collected for 3 h for the measurement of plasma glucose and serum insulin concentrations, utilized to calculate the insulin sensitivity index Si | 12 weeks |
| Measure | Description | Time Frame |

| Postprandial Insulin Changes | Blood samples during the standard meal test were drawn from an antecubital vein after a 12 h overnight fast and 0, 30, 60, 90, 120, 150 and 180 min postprandial for the measurement of plasma insulin response reported as average mean postprandial increment. | 12 weeks |
