M. Naruszewicz, M. Koz£owska-wojciechowska Potential Parapharmaceuticals in the Traditional Polish Diet

The basic parapharmaceuticals in the Polish diet include natural anti-oxidants bioflavonoids found in berry fruit. They were proven to have the ability to regulate genetic transcription and increase the synthesis of nitric oxide which counteracts dysfunction of the vascular endothelium. They also display anti-oxidant action through the inhibiting effect on cyclooxygenase COX-2, and increase the level of adiponectin. We have also more and more proof of the important biological role of short-chained fatty acids formed as a result of fermentation of fibre by probiotic bacteria. Through their effects on peroxisome proliferators activated receptors (PPAR), butyric and propionic acids may reduce the expression of adhesion molecules and exert anti-inflammatory action both in the gastrointestinal tract as well as systemically.
