Clinical Trial 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.


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
