[Consumer behavior toward functional foods. The role of authentic information]. / Az egészségvédo élelmiszerekkel kapcsolatos fogyasztói magatartás. A hiteles tájékoztatás szerepe.

Nowadays, we are witnessing a spectacular improvement in health consciousness of advanced societies. Due to the transformation of consumer behaviour, the proportion of health-conscious consumers who make well-informed and independent decisions increases steadily. In parallel, health-promoting foods are gaining more ground in the markets. Regarding the health effects, primarily cardiovascular prevention, bacterial flora modification, weight reduction as well as energy and vitamin supplementation are in focus in Hungary. Practically, any food type can be enriched with functional attributes; however, in addition to technical difficulties, the main challenge for food manufacturers is to persuade consumers to try out their products and use them continuously. In addition to research, development and innovation, consumer awareness and continuous knowledge expansion are also key factors for the success of functional foods. Consequently, strengthening the collaboration between functional food manufacturers and health professionals and researchers would be particularly beneficial, since their interrelationships might have a significant impact on the development and acceptance of novel functional foods.

Orally delivered sour cherry seed extract (SCSE) affects cardiovascular and hematological parameters in humans.

In the present study, we investigated the effects of sour cherry seed extract (SCSE) on a variety of systemic processes that contribute to general health and viability of human subjects. The experiments were conducted according to a double-blind protocol in which six healthy individuals were administered 250-mg/day SCSE for 14 days, while four were treated with placebo. Peripheral blood was collected before and after the treatment period. Samples were analyzed for levels of selected cells, enzymes, or metabolites. Subjects that received SCSE showed increases in the values of mean cell volume, serum transferrin, mean peroxidase index, and representation of peripheral blood lymphocytes. On the other hand, decreases were observed in circulating neutrophils and ferritin levels. Changes observed in the present study do not fit into a clear pattern that might yield additional in-depth understanding of SCSE-mediated alterations in physiologic responses. The most encouraging result of the present study is the absence of any indication of toxicity by subjects consuming the extract.
