Randomised, controlled, double-blind clinical study on the effect of a functional milk-product on metabolism of men with diagnosed metabolic syndrome

INTERVENTION: The volunteers of the verum group will take one portion of the functional milk‐product (product code 966125, a non‐registered product) once a day after lunch with a dessert for 56 days. The product of the control group is based on meat protein and is isoenergetic and isonitrogenous. Primary and secondary outcome measures will be analysed before and at the end of the intervention. CONDITION: Metabolic syndrome ; Nutritional, Metabolic, Endocrine ; Metabolic syndrome PRIMARY OUTCOME: Change of blood fructosamine concentration during the intervention period SECONDARY OUTCOME: 1. Insulin sensitivity; 2. Endothelial function; 3. Blood pressure; 4. Waist‐to‐hip ratio; 5. Postprandial concentration of several hormones and blood parameters linked to fat and carbohydrate metabolism INCLUSION CRITERIA: Men, 45‐70 years old, with a metabolic syndrome as defined by the International Diabetes Federation, 2006 (A new IDF worldwide definition of the metabolic syndrome: the rationale and the results ‐ Diabetes Voice, Vol. 50 Issue 3, 2005)
