Plant miRNAs In Human Plasma After Broccoli Consumption

Detection Of Plant miRNAs After Broccoli Consumption In Human Plasma: Role Of "Cross-Kingdom" Regulation

Nutritional clinical study to evaluate the absorption and presence of exogenous miRNAs from broccoli in plasma and peripheral blood mononuclear cells (PBMCs) and to determine their possible implication in the modulation of fecal miRNAs and gut microbiota in healthy volunteers.

Nutritional clinical study to evaluate the absorption and presence of exogenous miRNAs from broccoli in plasma and in peripheral blood mononuclear cells (PBMCs) and determine their possible involvement in the modulation of fecal miRNAs and gut microbiota in healthy volunteers. For this purpose, two nutritional interventions will be carried out: the first will consist of an acute intake to evaluate the pharmacokinetics of exogenous miRNAs of broccoli in human plasma, and the second will be a sustained daily intake of 200g broccoli for a duration of 2 weeks.

Inclusion Criteria:

• Men and women > 18 years and < 45 years
• Adequate cultural level and understanding of the clinical study.
• Agree to voluntarily participate in the study and give their written informed consent.

Exclusion Criteria:

• Not willing to consume the food in the required quantity and/or frequency.
• Subjects with severe disease (hepatic, renal, cardiovascular, etc.)
• Subjects under any type of pharmacological treatment.
• Having taken antibiotics 1 month before the start of the study (Specific for the 2-week long study).
