Polyphenols have been the goal of many studies over the past decades because of the newly-discovered positive effects on human health. In this thesis, individual groups of polyphenols and blood plasma proteins are described in more detail. Absorption, transport and elimination of polyphenols and the problems of absorption into the body are presented. Polyphenols are transported in the body primarily with blood plasma proteins. Some methods for the study of polyphenol-plasma proteins interactions and the resulting complexes are described. The interactions between them can be reversible or irreversible. Since the interactions are strongly influenced by the structure of polyphenols, a more detailed overview is made of how the replacement of groups on individual rings of some polyphenols affect the affinity for blood plasma proteins. Examples of the effects of polyphenols on our health are given and what can be expected of polyphenols in the future.
