To assess the influence of preferences on food and nutritional intake in a group of adolescent high-level athletes, 22 male soccer players (14-16 years) were recruited. Individuals were asked to fill in a specific questionnaire including 15 food groups that had to be ranked according to their preferences. Three categories were established: "Like" (ranked 1-5), "Indifferent" (6-10), and "Dislike" (11-15). Dietary intake was assessed using the weighed food method (for nutrient intake) and a quantitative open-ended food frequency questionnaire (for the number of standard portions of each food group ingested daily). The main preferences were Meat, poultry and derivates (ranked 1-5 in 83% of individuals) and Pasta (58%), while Vegetables (ranked 11-15 in 82%) and Fish (64%) were the main dislikes. The most frequently consumed food groups were Fruits and fruit juices (3.9 portions/day), Bread (3.0), and Biscuits, confectionery and sweets (3.0). No statistical differences were found in food consumption between preference groups, and no relation was found between preferences and nutritional intake, except for those individuals who especially like Bread, which had statistically higher energy and carbohydrate intake. Food preferences and food and nutritional intake of adolescent high-level soccer players were, effectively, unrelated.

The Turkish fast food industry has grown rapidly since the 1980s. There are now more than 700 fast food restaurants in Turkey. Using the data from a consumer survey, this study investigates the relationship between consumers' fast food consumption frequency and their socio-economic/demographic characteristics and attitudes. Using Chi-square test of independence, the study compares consumers' fast food consumption frequencies of never, low, moderate and high. We developed an empirical model identifying consumer characteristics that influence the consumption frequency of fast food products using the random utility framework. The empirical model was estimated using an ordered probit approach to obtain the coefficients applied to the calculation of marginal effects and probabilities. The sign and significance of coefficients and marginal effects were used to ascertain consumer characteristics which are important to the frequency of fast food consumption. The results indicate that age, income, education, household size, presence of children and other factors, such as consumer attitude towards the price of fast food, health concerns and child preference, significantly influence the frequency of fast food consumption. The findings will help fast food managers to understand the critical factors that influence consumers' fast food consumption behavior and help them to make improvements accordingly..

Consumers appear to be cautious about accepting novel technologies applied to foods because of perceived risks and lack of benefits. Text descriptions of novel technologies were tested at four locations around Australia on 453 prawn consumers. Half of the participants (Information treatment group) received additional information about the technologies. A conjoint study was undertaken with additional responses to questions on perceived risks, benefits, need, unnaturalness and safety of the technologies (beliefs). Recognition of the additional information was tested by an open question at the end of the task. Information treatment did not influence responses. Participants were segmented by the sum of their beliefs. Those (mostly male), classified with strong positive beliefs (15%), placed on average, less importance upon technology but an equal amount on cost and size of the product concepts. For those (mostly female), classified with strong negative beliefs (17%), technology was of greater average importance, with a greater range of (dis)utilities across the technologies. All participants favoured regular prawns to those treated with novel technologies although one technology (Triploidy) did receive relatively positive utilities possibly related to information that triploidy is sometimes "found in nature" and results in larger prawns. Generally, addressing "information deficit" did not overcome aversion to novel technologies applied to food concepts..

Cletus signatus Walker (Heteroptera-coreidae) feeds on a wide range of host plants namely Amaranthus spinosus, Amaranthus viridis, Amaranthus oleracea, Spinacia oleracea, Chenopodium album, Chenopodium anthelminticum, Millets, Cow pea, Lucerne, Juglans and Lagenaria vulgaris etc. Some experiments were carried out in the laboratory on the food preference of this insect using aforesaid host plants. It was discussed that C signatus feeds mainly on the host plants belonging to the family Amaranthaceae. Further, among the members of this family, A. spinosus is the most preferred host plant of the bug. On this food plant it has favour to inflorescence and younger seeds than the other parts of the plant. This preference is due to some unknown aminoacid or alkaloid occurring mainly in abundance in A. spinosus.

There is an increasing emphasis on understanding the consumer's motives for the choice of food types. Meanwhile, an individual's food-related personal traits are suspected of playing a moderating role in influencing personal food choice. This study aims to understand what motives determine the consumer's attitude to organic foods in Taiwan, which in turn influence the subsequent purchase intentions. Moderated regression analysis (MRA) is used to ascertain the personality traits of food neophobia and food involvement separately in the behavioral intentions model. The results vindicate the use of Ajzen's Theory of Planned Behavior (TPB) in explaining the consumer's organic foods choice behavior. Moreover, the findings suggest that the food-related personality traits of food neophobia and food involvement exert moderating effects on the relationships between some of the food choice motives and the consumer's attitude to organic foods. However, only food involvement exerts moderating effects on the relationships between the consumer's intentions to purchase organic foods and the antecedents of the TPB except for the subjective norm in this case. Based on the empirical results and findings, some suggestions are provided to the institutions concerned so as to facilitate this organic sector's on-going expansion in Taiwan's food industry..

Our food products are unthinkable without additives which, in fact, frequently render the high degree of convenience possible. Consumers, on the other hand, today want "less chemicals in food", but still do not wish to do without the advantages involved. In many fields "E numbers" may be replaced by alternatives without distinct losses in quality. In many cases, however, the "perfect product" is only achieved by the use of compounds subject to declaration. A change in thinking on all levels (production, trade, consumers) could reduce the number of additives used. Additives are subject to strict legal regulations which are regularly adapted to the present state of scientific knowledge in order to guarantee safety for consumers.

Although experimental studies have reported a wide array of other-regarding behavior, the pervasiveness of such behavior in the field is an open question. Using a stated-preference experiment, we first estimate people's preferences, when purchasing food products, for the distribution of benefits accruing to participants in the food supply chain. Although none of the existing fairness models exhibit much predictive power, we find that people are in-fact concerned about the distribution of benefits resulting from food purchases, and that modifications to the models to fit the food context significantly improves explanatory power. Finally, we find that the measured preferences, along with elicited beliefs are significant predictors of people's willingness-to-pay a premium for organic food.

The paper aims at studying consumers' acceptability of cured ham. A Double Censored Tobit is applied, in order to first, evaluate to what extent the information conveyed by an array of observable characteristics (origin, quality certification label, brand and breed) affects consumers' hedonic valuation of cured ham in both, blind and informed experimental conditions; and second, estimate the influence of some individuals' traits on their preference towards specific ham attributes. In particular, we study if personal rooting in the region and store loyalty leads to a better hedonic valuation of regionally produced ham and store brands, respectively. Iberian breed and the own regional origin are the most influential attributes in blind and informed scores, while a foreign origin is further penalized when recognized. The Quality Certification Label (PDO, PGI or TSG) conveys valuable information to consumers only in some specific cases (ej. PDO Teruel), while the Distributors' brand, when attached to superior quality categories, has a higher impact on overall liking than a Producers' brand. The cognitive component of the origin Teruel as a cue for quality prevails over the affective component while no relationship has been found between store loyalty and the hedonic valuation of store brand..
