Brief Summary
Scientific evidence shows that a major consume of flavonoids is associated with a minor risk of coronary disease and a modification of the gut microbiome profile. Dark chocolate has a major quantity of flavonoids by weight in comparison to wine, dark tea, blueberry juice, apples and, in particular the flavanols (i.e. catechin, epicatechin and procyanidin) can have protective and metabolic effects with reduction of the insulin resistance and improvement of the endothelial function in adults. In line with the aforementioned evidence, the present study has the aim of analyze the effect of dark chocolate (70%) on cardiovascular risk and on the metabolism in a population with mild dyslipidemia.

Estimate of microbial Shannon's (H') diversity from 3g faecal sample: Heterotrophic aerobic and anaerobic bacteria Total anaerobes Lactic acid bacteria Lactobacillus Lactococcus and Streptococcus Staphylococcus Bacteroides Porphyromonas and Prevotella Enterobacteria Aeromonas and Pseudomonas Bifidobacterium Enterococci
Baseline
Study Arms (2)
Chocolate
EXPERIMENTAL20 patients (matched per gender) undergoing a diet which includes 25g of dark chocolate (70%), i.e. ca. 145 kcal per day
Control
NO INTERVENTION20 patients (matched per gender) undergoing a low-fat dietary regimen
Interventions
20 patients (10 male, 10 female) will undergo a diet containing 25g of dark chocolate (70%), corresponding to ca. 145 kcal which will be detracted from the total caloric intake.
