Design outcomes

Primary

MeasureTime frame
Fecal samples are collected for the analysis of lipid excretion during the last three days of each treatment period.

Secondary

MeasureTime frame
1. Clinical history is measured both by interviews and previous clinical data at baseline 2. Anthropometric measures are collected taking height and weight at baseline and at the end of the study period 3. Nutrient intake and dietary habits are measured using a seven day food record validated nutritional questionnaire at baseline and at the end of the study period 4. Blood pressure is measured using a blood pressure cuff at baseline and at the end of the study period 5. 24 hour ambulatory blood pressure is measured using blood pressure cuff at baseline and at the end of the study period 6. Plasma TC is measured using a Diacron International Free Carpe Diem spectrophotometer (Grosseto, Italy), and commercially available kits from Diacron International at days 8, 18, 25 and 35 of the study period 7. HDL-C is measured using a Diacron International Free Carpe Diem spectrophotometer (Grosseto, Italy), and commercially available kits from Diacron International at days 8, 18, 25 and 35 of the study period 8. LDL-C is measured using a Diacron International Free Carpe Diem spectrophotometer (Grosseto, Italy), and commercially available kits from Diacron International at days 8, 18, 25 and 35 of the study period 9. Triglyceride levels are measured using a Diacron International Free Carpe Diem spectrophotometer (Grosseto, Italy), and commercially available kits from Diacron International at days 8, 18, 25 and 35 of the study period 10. Blood analysis (AST, ALT, ?-GTP, ALP, LDH, Albumin, Total bilirubin, Creatinine) is measured using a Diacron International Free Carpe Diem spectrophotometer (Grosseto, Italy), and commercially available kits from Diacron International at days 8, 18, 25 and 35 of the study period
