Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study seeks 40 adults aged 20-50 with normal or slightly overweight (by BMI) who regularly consume cocoa/chocolate. After recruitment, participants will receive a detailed explanation of the objectives and conditions of the study and will sign the informed consent and will be randomly assigned to randomly divided into two groups: Control Group that consumes a daily beverage with low-flavanol cocoa or the intervention group that consumes a daily beverage with high-flavanol cocoa. Participants in each intervention arm will be matched by BMI category (normal weight or overweight), sex (female or male), and age (plus or minus 5 years). Both groups will consume a single daily serving (8 grams) of their assigned cocoa (packaged individually) dissolved in low-fat and lactose-free milk (200 ml) before or with their breakfast. At baseline (time 0) and at the end of the intervention (12 weeks), each participant will be assessed for biological indicators gastrointestinal health, the composition of the gut microbiota and cerebrovascular health, markers associated with neuroinflammation, oxidative stress, and barrier function.
