Brief summary: Oxidative stress and inflammation are involved in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Anthocyanins from different plant foods have been shown to improve features of experimental NASH, such as oxidative stress, dyslipidemia, liver steatosis, and inflammation in rodents. The purpose of this study is to investigate whether purified anthocyanin supplementation beneficially alters oxidative, inflammatory, and apoptotic biomarkers in adults with features of NAFLD.


Eligibility criteria: Inclusion Criteria:

* BMI \[body weight divided by height squared (in kg/m2)\] \> 23,
* lack of excessive alcohol ingestion confirmed by careful questioning by the primary physician and dietitians (consumption of less than 70 g alcohol in female and 140 g in male per week), and
* the presence of two of the three following diagnostic criteria of the fatty liver disease: increased hepatic echogenicity compared to the spleen or the kidneys, blurring of liver vasculature and deep attenuation of the ultrasonographic signal.

Exclusion Criteria:

* overuse of alcohol,
* viral hepatitis,
* type 1 or 2 diabetes,
* gastrointestinal or connective diseases,
* chronic pancreatitis,
* liver cirrhosis,
* kidney stones, or renal failure;
* use of acetyl-salicylic acid or other antiplatelet drugs, statins of fibrates, oral hypoglycemic drugs, nitrates, nonsteroidal antiinflammatory drugs, corticosteroids, or drugs interfering with coagulation;
* supplementation with vitamins or antioxidants
