The purpose of this study is to determine the impact of moderate intensity exercise on acute post-exercise energy intake (EI) in normal and overweight females. Twelve normal weight (BMI<25), and 12 over weight (BMI>25) inactive women (mean age 35+/-8) participated in a 2-day experimental study. On the exercise day, participants were asked to walk on a treadmill at 60% maximum heart rate for...
Functional foods presumably enable the consumer to lead a healthier life without changing eating habits. Whether consumers accept this proposition or not is potentially influenced by their perceptions of the healthiness of the processing methods, enrichment components, food-types, and health claims used in the production and marketing of functional foods. Because consumers may perceive functional...
Previous research has demonstrated that family members' eating habits are similar. We hypothesized that family members' eating habits would be predicted by the eating habits of the person who prepares the majority of the family's meals and the number of meals the family shares. Participants were 282 members of religious organizations who identified themselves as family food preparers (FFPs), and provided...
The present study makes a start on characterising the cognitive processes by which physical effects of eating on the senses are transformed into quantitative judgments about perceived characteristics of a food. It was hypothesised that there is a discrete perceptual channel for an aspect of texture sensed during each of the three initial movements of eating a piece of a cookie. The results showed...
Individuals entering marriage merge their personal food systems to create a joint spousal food system. This investigation examined newly married couples' food choices. Qualitative interviews conducted with 20 couples as they entered marriage and again 1 year later revealed that some reported initial food homogamy, while others had varying degrees of compatibility in food preferences and tolerances...
One-year-old children who failed to thrive in infancy were identified through a specialist clinical service using a conditional weight gain criterion which identified the slowest gaining 5%. Control children of the same age and sex were recruited from the same local geographical area and had the same primary care physician. The food intake and feeding behaviour of the groups was compared using a detailed...
To gain insight into the effect of oral processes on perception, we defined a set of five specific oral manipulations and investigated their effects on the perception of low and high fat versions of two semi-solid foodstuffs, vanilla custard desserts and mayonnaises. Behavior modifications ranged from simply placing the stimulus on the tip of the tongue to vigorously moving it around in the mouth...
This study investigated schoolchildren's breakfast choices focusing on their reported usual intake and perceptions of fat-reduced or fibre-enriched alternatives. A total of 184 eleven- to fifteen-year-old were asked to participate, and 181 completed the study. Using pictures of food items, the children were instructed to reproduce their usual breakfast, and then breakfasts that would be: healthy,...
Food deprivation and restriction both increase food consumption. Food deprivation also increases the reinforcing value of food, but it is unknown if food restriction alone or combined with deprivation increases the reinforcing value of food. Forty, normal-weight, college-aged, unrestrained females were randomized to one of four conditions that crossed food deprivation (Dep) and restriction (Res):...
Using confirmatory factor analysis, we cross-validated the factor structures of the Spanish versions of the State and Trait Food Cravings Questionnaires (FCQ-S and FCQ-T; Cepeda-Benito et al., 2000a) in a sample of 304 Spanish college students. Controlling for eating disorder symptoms and food deprivation, scores on the FCQ-T were higher for women than for men, but no sex differences were observed...
The primate dopamine system is involved in appetitively motivated behaviours, including certain forms of learning, for example, visual discrimination learning. Furthermore, food restriction in animals and anorexia in humans is associated with impaired dopamine signaling. Based on this, we hypothesized that patients with anorexia nervosa (AN) would show a deficit in visual discrimination learning....
Despite considerable epidemiological evidence of the health benefits of a diet high in fruit and vegetables, consumption in pre-school children remains well below recommended levels. This study evaluated the effectiveness of an exposure-based intervention, carried out by parents in the home, in increasing children's liking for a previously disliked vegetable. 156 parents of 2-6 year old children were...
This study characterized associations of restraint with selected physical, lifestyle, personality and menstrual cycle characteristics in female university students. The survey instrument, distributed to 1350 women, included standardized questionnaires (Three-Factor Eating Questionnaire, Perceived Stress Scale and Rosenberg's Self-esteem Scale), and assessed weight and dieting history, exercise, lifestyle...
We designed a questionnaire concerned with attitudes and behaviour towards organic foods, environmentally friendly behaviour (EFB), and perceived consequences of organic food choice in terms of human health, the environment and animal welfare. It was mailed in 1998 to a random nation-wide sample of 2000 Swedish citizens, ages 18-65 years, and 1154 (58%) responded. Self-reported purchase of organic...
The present study investigated the question of whether the previously observed impairments of working memory characteristic of dieting to lose weight can be explained in terms of preoccupying cognitions relating to body shape or to alterations in serotonergic function resulting from a low dietary intake of tryptophan. The population comprised female non-dieting, lower restrained eaters (N=23), non-dieting...
The aim of the present study was to relate appetite ratings before and after a standard breakfast to estimates of daily energy intake, before and after weight loss obese men and women. Nineteen obese subjects (9 men and 10 women) took part in a 15-week drug-based weight-loss program coupled to energy intake restriction. Body weight and body composition were significantly decreased in men and women...
The food neophobia scale [FNS; Appetite 19 (1992) 105] has been used to assess willingness to try new foods in studies conducted around the world. Although it is tempting to compare FNS scores across these studies, appropriate psychometric analyses are required to validate the scale and allow cross-cultural comparisons. These analyses were pursued in the current study using confirmatory factor analysis...
