Effect of Tomato Extracted Lycopene on Postprandial Oxidation and inflammation in Healthy Weight Men and Women

Not Applicable

Completed

• Conditions: Postprandial Oxidation and inflammation
• Interventions: Dietary Supplement: Tomato extracted lycopene; Dietary Supplement: Placebo

• Registration Number: NCT01665469
• Lead Sponsor: LycoRed Ltd.

Brief Summary

The hypothesis of the study is that tomato extracted lycopene will be able to decrease postprandial oxidation and inflammation in healthy weight men and women when compared to Placebo.

Detailed Description

Consumption of a high-fat meal results in a postprandial (fed-state) response characterized by hypertriglyceridemia. Postprandial hypertriglyceridemia increases the oxidation of low-density lipoproteins (LDL) and increases blood concentrations of several biomarkers of inflammation. This postprandial lipemia-induced oxidative stress mediated response to a high-fat meal has been suggested as a major contributor to the pathogenesis of atherosclerosis along with other chronic disease states of diabetes and obesity. Consumption of foods rich in antioxidant compounds provides a defence source to compliment endogenous defence systems to protect against oxidative damage during pro-oxidant conditions.

8. Subjects is willing to sign an informed consent form prior to joining the study

Exclusion Criteria

1. Subjects suffering from overweight defined as BMI > 25 kg/m2
2. Subject that is actively losing weight (e.g. are on a diet) or subjects with greater than 5% change in body weight within 1 month prior to the randomization visit
3. Subject taking lipid-altering drug therapy within six weeks prior to screening. Also excluded are supplements known to have significant lipid altering effects, such as niacin, garlic, omega-3 fatty acids, red yeast rice extract, phytostanols / phytosterols, soluble fiber, chitosan and conjugated linoleic acid
4. Subjects using the following medications: systemic corticosteroids, orlistat, bile acid resins, prescription omega-3 fatty acids, cyclical or non-continuous hormone therapy

11. Subjects that has a diagnosis of type 1 or type 2 diabetes mellitus
12. Subjects that has high serum thyroid-stimulating hormone
13. Subjects that has aspartate aminotransferase (AST) or alanine transaminase (ALT) > 3 times the upper limit of normal
14. Subjects that has Creatinine ≥ 1.5 mg/dl
15. Subjects that has high-sensitivity C-reactive protein
16. Woman subjects with positive pregnancy test
17. Woman subjects that are breast feeding, pregnant, or planning on becoming pregnant during the duration of the study
18. Subjects with known cardiovascular disease or stroke, except for conditions that are deemed clinically insignificant by Principle Investigator or Sub-investigator, or study site physician (e.g. clinically insignificant atherosclerotic lesions observed by imaging studies).
19. Subject with history of significant gastrointestinal disease such as severe constipation, diarrhea, malabsorptive disease, inflammatory bowel disease (e.g. Crohn's disease, ulcerative colitis)
20. Subject with history of severe psychiatric illness which in the opinion of the investigator would interfere with the optimal participation in the study
21. Subject with history of bariatric surgery
22. Subject with history or current use of illegal or "recreational" drugs
23. Subject that used any investigational drug(s) 60 days prior to screening
24. Subject that participate in any other clinical trial while participating in this trial
