Study Details
Study Description
Brief Summary
The aim of the present clinical study is to estimate the efficacy of a honey-based gel, derived from the wider area of Pindos in Greece, in regulating oxidative stress biomarkers and the physiological profile of healthy adults.

Detailed Description
Introduction: Honey contains about 200 compounds such as sugars, proteins, vitamins, water, free amino acids, enzymes, minerals, and many phytochemicals. Due to its composition, enriched with many bioactive ingredients, several studies have established its antimicrobial, antiviral, anticancer, antidiabetic and antioxidant properties. This multilayer activity of honey has been proposed for the protection against pathologies interrelated with the cardiovascular, nervous, respiratory, and gastrointestinal system.
Purpose: This study aims to investigate the effects of a novel natural honey-based gel consumption on oxidative stress biomarkers, blood chemistry and physiological characteristics in healthy individuals.
Methodology: A total of 20 healthy men and women will participate in the study. Participants will give their informed consent after they will be informed about the purposes, procedures, risks and benefits associated with the study. Participants will consume 70 g/day of the honey-based gel, distributed in 2 equal doses (in the morning and evening) for 14 days. At baseline and post-intervention, volunteers will be assessed for their physiological profile and will provide a resting blood sample for the assessment of oxidative stress and blood chemistry biomarkers as well as their physiological profile. Participants will be asked to record their diet for 3 days prior to the study and they will be asked to follow the same dietary pattern for 3 days before the post-intervention assessments.
