Evaluation of a New Orange-Based Beverage Enriched With Polyphenols in Adult Humans (BIONAOS)

Evaluation of a New Orange-Based Beverage Enriched With Polyphenols (Whole Press) on Features of Metabolic Syndrome and Cardiovascular Risk Factors Related to Inflammation and Antioxidant Defense System in Adult Humans

The purpose of this study is to evaluate the effects of a new orange juice-based beverage enriched in fiber and selected phenolic compounds (mainly flavanones) on features of metabolic syndrome and cardiovascular disease risk factors related to inflammation and antioxidant defense system in overweight and obese adult humans. This study hypothesizes that consumption of an orange juice-based beverage enriched in fiber and selected phenolic compounds (mainly flavanones)would improve lipid levels and lipid metabolism,blood pressure and the Homeostatic Model Assessment (HOMA) index.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Systolic blood pressure		3 months
Fasting Plasma Insulin Concentration		3 months
Fasting Plasma Triacylglycerols Concentration		3 months
Fasting Plasma High-Density Lipoprotein Cholesterol Concentration		3 months
Insulin resistance using HOMA (Homeostatic Model Assessment)index	The HOMA index will be calculated as the product of the fasting plasma insulin level (mU/mL) and the fasting plasma glucose level (mmol/L), divided by 22.5	3 months
Fasting Plasma glucose concentrations		3 months
Diastolic blood pressure		3 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Antioxidant defense system	Biomarkers of the non-enzymatic (NE-ADS) and enzymatic antioxidant defense system (E-ADS). For the NE-ADS, in addition to total plasma antioxidant capacity, malondialdhyde, and total carbonyl protein derivatives, plasma α-tocopherol, β-carotene, retinol, coenzyme Q and total blood glutathione will be determined. Furthermore, the amount of plasma oxidized LDL and urinary 8-hydroxy-2'-deoxyguanosine and F2-isoprostanes will be measured. For E-ADS the activities of glutathione reductase, glutathione peroxidase, superoxide dismutase, and catalase in red blood cells will be assessed.	3 months
Biomarkers of inflammation	Biomarkers of inflammation: Interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), matrix metalloproteinase-9 (MMP-9), monocyte chemotactic protein 1 (MCP-1)and polymorphonuclear neutrophils myeloperoxidase (MPO)	3 months
Biomarkers of cardiovascular risk.	Biomarkers of cardiovascular risk:soluble endothelial selectin (sE-selectin), soluble intercellular adhesion molecule 1 (sICAM-1), soluble vascular cell adhesion molecule (sVCAM-1), total and active tissue plasminogen activator inhibitor-1 (tPAI-1), tumor necrosis factor alpha (TNF-α).	3 months
Metabolic analysis	Gastrointestinal hormones involved in the control of satiety and insulin secretion i.e. active amylin, ghrelin (GHR), glucagon peptide-1 (GLP-1), gastric inhibitory peptide or gastric insulinotropic peptide (GIP), polypeptide YY 3-36, pancreatic polypeptide (PP). Likewise, adiponectin, leptin, resistin, visfatin, hepatocyte growth factor (HGF), nerve growth factor (NGF), retinol binding protein 4 (RBP4) and L-fatty acid binding protein (L-FABP) will be determined	3 months
Gene expression analysis	Whole genome gene expression analysis: This analysis will be carried out in a subset of 20 control and 20 experimental samples at four times: 160 arrays. The GeneChip® Human Exon 1.0 ST will be used for the gene expression analysis. Validation by Reverse transcription polymerase chain reaction (RTPCR): In order to confirm the arrays results, a total of 93 differentially expressed genes in the experimental samples will be analyzed by RTPCR using low density arrays	3 months
