Human studies provide evidence for beneficial effects of polyphenol-rich foods on cardiovascular health. The antioxidant activity of polyphenols potentially explains these effects, but is the antioxidant activity a reliable predictor for these effects? An International Life Sciences Institute Europe working group addressed this question and explored the potential of antioxidant claims for polyphenols in relation to cardiovascular health by using the so-called Process for the Assessment of Scientific Support for Claims on Foods project criteria. In this process, analytical aspects of polyphenols, their occurrence in foods, dietary intake, and bioavailability were reviewed. Human studies on polyphenols and cardiovascular health were reviewed together with methods for biomarkers of oxidative damage and total antioxidant capacity (TAC). In retrospective studies, F2-isoprostanes and oxidized LDL, the most reliable biomarkers of lipid peroxidation, and measures for TAC showed the expected differences between cardiovascular disease patients and healthy controls, but prospective studies are lacking, and a causal relationship between these biomarkers and cardiovascular health could not be established. Therefore, the physiological relevance of a potential change in these biomarkers is unclear. We found limited evidence that some types of polyphenol-rich products modify these biomarkers in humans. A direct antioxidant effect of polyphenols in vivo is questionable, however, because concentrations in blood are low compared with other antioxidants and extensive metabolism following ingestion lowers their antioxidant activity. Therefore, the biological relevance of direct antioxidant effects of polyphenols for cardiovascular health could not be established. Overall, although some polyphenol-rich foods exert beneficial effects on some biomarkers of cardiovascular health, there is no evidence that this is caused by improvements in antioxidant function biomarkers (oxidative damage or antioxidant capacity). © 2011 American Society for Nutrition.

Important differences have been reported in several countries about the level of concern in connection with food additives. In order to better understand the consumer preferences related to foodstuffs containing food additives, five hypotheses were tested with the help of a choice-based conjoint analysis. The study was performed in three European countries (Hungary, Romania, and Spain) having different risk perceptions concerning food additives. Two "model foodstuffs" were involved in the analysis: pre-packed sliced cheese (natural image) and chips (artificial image). For the creation of the conjoint cards, three attributes were selected: "preservatives" (natural/artificial), "packaging gases" (contains/does not contain) and "price" (average based on market data/+10%/+20%). Results were collected via Internet simultaneously and a total of 500 valid questionnaires were received in case of pre-packed cheese and 468 regarding chips. In the analysed countries "preservatives" had an outstanding importance - mainly in Hungary and Romania -, while "packaging gases" got lower importance during the shopping intention. "Natural preservatives" very positively contributed to the choosing of both pre-packed sliced cheese and chips. High level of willingness to pay was not observed, as well as the "price" was less important factor than the additives. Comparison of the data from three countries showed notable differences, which can determine the direction of the product planning and development. © 2014 Akadémiai Kiadó, Budapest.

Introduction: Nowadays the number of people suffering from different non-communicable diseases is continuously rising. However, the risk of the incidence of these diseases can be reduced with the help of conscious and healthy lifestyle. Aim: The main aim of the study was to explore Hungarian consumers' attitude related to healthy diet. Method: A questionnaire survey was conducted with 473 respondents. Results: According to the participants it is difficult to make head or tail of information about healthy nutrition, and the "Internet" is the most frequently used source of information. With cluster analysis 3 significantly different consumer groups were identified: participants of the "ambitious" group show positive attitude towards healthy diet; the "health conscious" cluster cares about and actively supports health and diet; and members of the "indifferent" cluster are less interested and do not make a remarkable effort for their healthy diet. Conclusions: Results of the questionnaire survey pointed out the importance of targeted information to relevant consumer groups, as well as the importance of popularization of accurate and reliable information sources. Furthermore, presentation and popularization of cost-effective healthy nutrition are of outstanding importance, especially for consumers in need (e.g. elderly, low-income people). Orv.

The utilisation of food consumption databases is widespread and involves for example, the risk assessment, understanding of consumers' food consumption trends, health education, and planning of prevention projects. Harmonisation of national consumption data for international comparison is an important and challenging work. First attempts started in the 70's and have been continuing up to now. The present study gives an overview of the collection methods, types and utilisation of food consumption data, as well of the most important phases of the international harmonisation work. As this study shows, it is crucial to harmonise the surveys parameters like the time of the data collection, method, number of participants, and number of the analysed days for an internationally comparable consumption database. From this point of view, the efforts of the EU menu project are promising.

Science assumed in recent decades an increasingly important role in the regulatory field. Regulatory science is now regarded as established specific brunch of science. A disturbing anomaly, the emergence of fraudulent data is of major concern both in the field of research and in the regulation. Hans Selye's work on stress, on several forms of pluricausal diseases and on other experimental models came into the focus of interest on the occasion of the Selye Symposium - 2013 held in May 2013 at the Hungarian Academy of Sciences in Budapest.
