The paper examines the benefit of bread enriched with antioxidants on oxidative stress, and on the quantities of hydrosoluble antioxidants in a group of human subjects. The home-management of functional foods strategy seeks to improve prompt and effective basic nutrition using additional attributes that are directly positively beneficial for health and well-being. The purpose of this clinical study was to test the tolerance and benefits of multicomponent functional foods enriched with antioxidant compounds obtained from plant extracts on healthy adult volunteers. A detailed protocol was created to formalize and standardize the procedures for data collection, e.g. filling out standardized forms and functional diet questionnaires. For the research method, Group A was given the special diet enriched with multicomponent antioxidant foods and Group B (control). The data were analysed using the quantitative methods. They showed significant increase of hydrosoluble antioxidants in group A compared to control, from 220.61+/-27.92 - 313.56+/-37.09 micrograms/mL (p=0.05), compared to 280.47+/-32.1 - 238.27+/-44.93 micrograms/mL (p=0.45). Also, oxidative stress values showed a decrease in the diet group compared to control that reached statistical significance. Oxidative stress decreased in the diet group to 244 +/- 89 compared to 308+/-108 UFORT in the control group. The responses of the prevention of chronic diseases to a functional foods strategy depend on how they are absorbed and utilized in the body. An anti-oxidant diet with natural bioactive components could become an interesting solution for degenerative disorders in which oxidative stress is increased.
