Within a survey made of Hungarian awareness of, attitudes towards, and preferences for food labels and pricing, this study focused on consumers’ reactions to quality and country of origin labels. Data were collected with a standard questionnaire, face-to-face interviews (1000 participants) in the respondents’ home. It became obvious that consumers were looking for information about quality (rating its importance at 4.04) on packages, but information about origin (3.94) and production (3.89) was also important to them. The capability of respondents to spontaneously recall country of origin and quality labels was very limited: 35.5% of all respondents could not name any such labels. The best known label was “Hungarian Product” (30.5%), which was recognized by up to 90% of the respondents after they were shown it. Many consumers were ready to pay premium for products bearing this label (31.7%). According to our results, information about quality is important to consumers, but they do not look for it deliberately, and only a few consumers ascribe a higher value to products with labels bearing this information. There is a pressing need to increase consumers’ confidence for trademarks through dissemination of reliable information.

The effect of synthetic beta-carotene and synthetic nucleotide base on daily weight gain, feed consumption and certain haematological, biochemical and immunological parameters of piglets were studied in a 3-week experiment. Beginning one week prior to weaning, the diet fed to one experimental group of piglets was supplemented with 10% Rovimix Beta-carotene at 875 mg/kg of diet. Synthetic uracil and adenine (98%, Sigma-Aldrich) were mixed into the diet of the other experimental group at doses of 500 mg/kg of diet for each substance. The control group received the basic diet without any supplementation. The changes observed over time in the haematological parameters and in certain biochemical variables could be regarded as physiological. By day 21 of the experiment, beta-carotene supplementation had significantly lowered the neutrophilic granulocyte percentage and elevated the lymphocyte percentage, while in the other two groups a change of opposite tendency occurred. At the end of the experimental period there was a decrease in plasma vitamin E concentration due to carotene supplementation (control: 6.1 ± 1.5, nucleotide: 6.3 ± 2.5, carotene: 2.3 ± 1.5 mg/L). Lymphocyte blastogenesis induced by phytohaemagglutinin and concanavalin A increased by 50 and 130%, respectively, in the nucleotide group and by 60 and 30%, respectively, in the carotene group, while it did not change in the control group. The supplements exerted no positive effect on the in vivo cellular immune response.

The contribution of food production to the environmental burden is considerable, therefore, numerous countries have been trying to create a sustainable food supply chain to ensure food and nutrition security. The scope of this study was to analyse the association between water footprint and healthiness based on dietary records. Furthermore, it was aimed to create a classification of integrative dietary indicators of sustainable nutrition. With these methodological aims, the dietary records of 25 healthy adults were assessed. The dietary quality scores and dietary water footprint were calculated and Spearman's rank correlation was tested between them. The indicator nutrients were classified based on their advantageous or disadvantageous health impact and association with water footprint. There was a significant positive correlation between the meat consumption and water footprint, while significant negative correlations were found between the dietary quality score and water footprint and dietary quality score and meat consumption (P < 0.05). Protein, energy, sodium, and saturated fatty acids as integrated indicator nutrients could be identified for both dietary quality and water footprint. The improvement in dietary quality could simultaneously decrease the dietary water footprint. The integration of environmental impact into the analysis of diets could be the future direction in the counseling practice of nutritionists.
