This study examines people's acceptance of genetically modified (GM) food. Results suggest that GM acceptance depends most on how natural the genetically modified product is perceived and not directly on how natural the non-GM product is seen. A GM product that is perceived as more natural is more likely to be accepted than a GM product that is perceived as less natural. The extent to which GM affects...
The effects of administration of mercaptoacetate (MA) and overnight food deprivation on intake of chow and milk diets were investigated in juvenile rats. In rats aged 25 or 30 days, administration of mercaptoacetate-stimulated intake of rat chow, while either suppressing intake or not affecting intake of milk diets. These effects were observed when each diet was presented individually, and when animals...
One would believe that with the increasing importance attached to consumers in contemporary affluent societies, the difficulty to understand today's ‘butterfly’ or ‘unmanageable’ consumers seems to double simultaneously. Modern consumers defy traditional segmentation by age, gender or income. Classical criteria to distinguish different homogeneous groups of consumers with corresponding behavioral...
Leptin deficiency has been associated with extreme obesity and hyperphagia in rodents and humans. A rare genetic disorder in humans yields the absence of the hormone leptin, extreme obesity, and a ravenous appetite. Reports on these rare cases have indicated that therapy using leptin injections can yield significant weight loss and changes in appetite. The aim of this report on acute leptin therapy...
This paper assesses the relationship between food consumption patterns and the use of agricultural land. First, it calculates the amount of land needed to produce singular foods, and second, it assesses land requirements of food consumption patterns. The paper observes large differences among requirements for specific foods. Especially livestock products, fats, and coffee have large land requirements...
This survey showed that the values power (dominance over nature and resources) and universalism (respect for people and for nature) are related to attitudes toward genetically modified food (GMF) and organically grown food (OGF). Furthermore, these values have an influence on the centrality, commitment and ambivalence of these attitudes. Values that are positively related to an attitude influence...
Current patterns of meat consumption are considered to be unsustainable. Sustainable development may require that consumers choose to eat smaller quantities of meat as well as meat that is produced in a more sensible way. A policy tool directed at consumer behaviour is that of enhancing consumer-oriented transparency of the production chain. Transparency is expected to allow people to make more mindful...
The availability of multiple sources of food and drink has a profound influence on choice behavior in rodents. It is not known how other taxa might respond to the same kind of variation in availability. We tested European starlings (Sturnus vulgaris) with various combinations of unadulterated and repellent-treated (0.025% citronellyl acetate) resources. In Experiment 1, birds drank more plain than...
While identity has been a dominant topic in research on food choice, literature on identity in consumers' everyday life is scarce. In this article we draw on insights from discursive psychology to demonstrate how members of an online forum on food pleasure handle the hedonic appreciation of food in everyday interaction. We examined 40 discussions consisting of 1715 e-mails related to culinary topics...
The disappearance of the ‘traditional’ meal was explored, comparing Flemish time budget data for 1988 and 1999. In 1988, 463 respondents between 21 and 40 years old kept a diary for three consecutive days. In 1999, 599 respondents followed the same procedure for a full week. Respondents registered all their activities, including timing, duration, location and other parties to the interaction. Respondents...
The first edition of Ons Kookboek (Our Cookbook), also known as ‘the culinary bible of Flanders’, was published in 1927 by the Belgian Women Farmers' Union. By 2000, an estimated 2.3 million copies had been sold. This exceptionally successful and long-running series of cookbooks represents a unique source of the history of Flemish cuisine and food culture. The aim of this article is to analyse how...
We tested the hypothesis that exercise energy expenditure (EEE) will elicit reflex metabolic compensations but no increases in hunger. Exercise expended 800kcal once when fasted and at another time in a post-prandial state. During fasting exercise, pre-meal ratings of hunger were unaffected by EEE, but plasma concentrations of ghrelin, growth hormone and free fatty acids were higher than in the absence...
The night eating syndrome (NES) is an eating disorder marked by a delay in the circadian pattern of eating that disrupts sleep. Studies have shown that those with NES eat a significant proportion of their calories after their evening meal and wake up during the night to eat. However, the timing of the sleep cycles are phase appropriate, with similar bedtimes and morning wake up times as control subjects,...
The Mediterranean diet is often characterized in terms of food items only. In this paper, the comparison of meals, in-between meals snack consumption and total daily food intake is presented between Sardinia and Malta in terms of structure, social environment and hours, together with their changes. Data were collected in 2001 in Sardinia and 2002 in Malta. A structured qualitative questionnaire, articulated...
This study examined how pharmacological and behavioral manipulations affect appetitive and consummatory aspects of feeding of baboons. Baboons have access to food 24h each day, but they must complete a two-phase operant procedure in order to eat. Responding on one lever during a 30-min appetitive phase was required before animals could start a consumption phase, i.e. a meal, where responding on another...
Appetite research frequently employs principles derived from behaviour analysis. However, it has yet to utilise the more recent theoretical advances in this field. This paper describes the concept of the motivating operation (MO)—a behaviour analytic formulation of motivation. An MO is an environmental event that (a) establishes or abolishes the reinforcing or punishing effect of another event and...
A series of studies in rat using isoenergetic (kcal/ml) liquid diets differing in fat content has previously found dietary fat to dose-dependently increase daily caloric intake. In single-meal tests in which meal initiation was externally evoked in feeding-associated environments, the behavioral expression of this overeating was found to be larger meal intake. The present studies confirmed the ecological...
The outcome expectancies of 250 respondents were examined using the Food Expectancy Questionnaire (FEQ), comparing expectancies about four different foods: fruit, vegetables, chocolate and sweets and plain biscuits. These expectancies were related to diet as assessed by a Food Frequency Questionnaire. As with alcohol expectancies [Jones, B. T., Corbin, W. & Fromme, K. (2001). A review of expectancy...
