Limiting meal variety decreases hedonic ratings of eaten foods more so than non-eaten foods, demonstrating sensory-specific satiety. Exposure to a food over time decreases the food's hedonic ratings, indicating monotony. The effect of limiting food group variety over time on long-term sensory-specific satiety and monotony is unknown. Thirty overweight adults ...

Today there is a strong trend in Sweden for industrially processed meals to replace homemade meals. In the public debate this is often claimed to increase the environmental impact from foods. In the study presented in this article, we used life-cycle assessment to quantify the environmental impact of three meals: ...

Total daily food intake of 16 preschool children 4-6 years of age were collected from 5 to 7 consecutive days. The most powerful determinant of the amount of food consumed at meals was amount served (r=0.77, P<0.0001). Although intake at meals (snacks were considered a meals) was significantly negatively correlated ...

Beverages are frequently consumed with meals, but their influence on meal energy intake is not understood. We hypothesized that differences in the energy, nutrient content, and sensory properties of beverages consumed with a meal would affect intake. Forty-four women ate lunch in the laboratory once a week for 6 weeks. ...

Effect of relative meal size (0.6-24%) on specific dynamic action (SDA) was assessed in southern catfish juveniles (48.2+/-3.2 g) at 27.5 degrees C. Cutlets of freshly killed loach species were used as test diet. Energy expended during SDA was linearly correlated with relative meal size (r=0.949, p<0.001, N=47). There was ...

The aim of this study was to evaluate the quality of meals during transport from the kitchens to the patients in three departments of a university hospital. ...

The aim of this study was to evaluate the clinical utility of appetite sensations to characterize individual overall energy intake. A group of men (n 28) and women (n 23) was recruited to record their 'desire to eat', 'hunger', 'fullness' and 'prospective food consumption' (PFC) on visual analogue scales before ...

Attempts to understand ingestion have sought to understand the control of meals. The present study evaluated a meal definition that included prandial drinking (drinking-explicit meals). The spontaneous nocturnal intake of male Wistar rats was studied. The meal breakpoint was defined as the interval between feeding or drinking events providing the ...

Diuretic therapy (DT) plays a major role in disease management. However, one issue of concern in nutritionally vulnerable elders is that diuretic therapy also increases thiamin excretion, and little attention has been paid to the linkage between DT use and dietary intake of thiamin in this older population. The purpose ...

Reliance on others for help with food-related activities (grocery shopping and meal preparation) [FADL] can influence food intake and can be considered part of the concept of food security for older adults. Data collected from 193 community-living seniors identified that 29.5% of these seniors required help with these activities. Covariates ...

Some factors influencing food intake and subjective responses to meals were assessed in 2 groups (n=40 and n=36) of healthy university students. Both groups were studied for 6 days and included both "structured" and "unstructured" times. A questionnaire was completed by all subjects at 3 h intervals while awake. The ...

BACKGROUND: Diminished appetite occurs frequently with aging and is considered an important clinical symptom of malnutrition, a condition associated with negative clinical outcome, decreased quality of life, and increased health care costs in hospitalized geriatric patients. Yet, in this population, research is scant on hunger and aversion, the two underlying ...

Malnutrition and the under-consumption of food in hospitals is prevalent and in UK hospitals, the consumption of meals is mainly a solitude event, despite evidence to show that eating in the presence of others can actually increase food intake. Dietary data were collected for three consecutive 24 h periods (n=13) ...

We report the meal patterns of mice with the deletion of either the melanocortin type 3 or 4 receptors (MC3RKO or MC4RKO) compared with that of the wild type (WT) under conditions of varying foraging costs. Mice lived in two-lever operant chambers; the completion of a designated number of responses ...

Laboratory data with single exposures showed that palatability has a positive relationship with food intake. The question addressed in this study is whether this relationship also holds over repeated exposures in non-laboratory contexts in more natural environments. The data were collected in four field studies, lasting 4-11 days with 307 ...

OBJECTIVE: A behavioral recommendation for weight loss is reduction of size of bites of food.

Young and Nestle suggested that the increase in the portion size of food products evident in the United States during the past 20 years may be responsible for the epidemic of overweight and obesity. They based their conclusion on statistical correlations. The purpose of the present study was to provide ...

All cultures dictate the need to feed the hungry and create rituals for almost every life passage around the consumption of food and beverage. Yet, in old age and among those who cannot advocate for themselves, mealtime is medicalized and demoted to an insignificant event without dignity or regard for ...

Prior work has demonstrated that melanin-concentrating hormone-1 (MCH-1) receptor antagonism decreases food intake and body weight in obese rodents. The purpose of this study was to determine if the MCH-1 receptor antagonist-mediated hypophagia was due a decrease in meal size, meal frequency, or both. We performed a meal pattern analysis ...

Animals behave in bouts, and the process that causes feeding bouts to end is called satiation. Bout size or, in the case of feeding, meal size is the result both of the costs of food resources and the consequences of consuming a particular resource. Meal size increases as a function ...

OBJECTIVE: To compare the diet history (DH) method to an estimated 7-day record (7-d) concerning meal pattern and intake of foods, energy and nutrients. DESIGN: After the DH interview, subjects completed the 7-d. SETTING: School setting, Göteborg, Sweden. SUBJECTS: A total of 51 adolescent girls (15-16 y) recruited from 634 ...

The investigation was carried out using the repertory grid technique and using written scenarios as the research stimuli. The nine scenarios successfully manipulated perceived convenience, time and effort. A consumer-generated vocabulary ...

This review's objective is to give a critical summary of studies that focused on physiologic measures relating to subjectively rated appetite, actual food intake, or both. Biomarkers of satiation and satiety may be used as a tool for assessing the satiating efficiency of foods and for understanding the regulation of ...

To better predict food effects on the bioavailability/bioequivalence of drugs and drug products from in-vitro data, a dissolution medium that simulates the initial composition of the postprandial stomach was developed. First, the physical parameters of two homogenized standard breakfasts often administered to assess food effects in pharmacokinetic studies were measured. ...

In an attempt to investigate the relative importance of endogenous and exogenous factors in determining food intake, 14 healthy subjects were studied while living in an Isolation Unit (where external time cues were absent) for eighteen 28 h "days" (equal to 21 solar days). The subjects were free to spend ...

We related the effect of the satiety enhancing drug sibutramine (Meridia, Reductil) on food intake to Rorschach Comprehensive System (Exner, 1991, 1993) personality factors. A placebo-controlled crossover, within-subjects design (n = 36) was used. Food intake after 2 weeks in the sibutramine and placebo conditions was assessed with a test ...

OBJECTIVE: Visual analogue scales are widely used in appetite research, yet the validity of these scales to evaluate appetite and mood has not been assessed in older subjects. The aim of this study was to determine the relations between food intake and visual analogue scale (VAS) ratings of appetite and ...

Background: Several aspects of the postprandial effects of meals need further investigation. In particular, we were interested in focusing on whether the glycemic effect of meals is related to the serum concentration of hormones known to be involved in appetite regulation, and to hunger and food intake. Objective/research questions: Will ...

In most individuals, food intake occurs as discrete bouts or meals, and little attention has been paid to the factors that normally determine when meals will occur when food is freely available. On the basis of experiments using rats, the authors suggest that when there are no constraints on obtaining ...

BACKGROUND: Ambulatory 24-h dual-channel pharyngeal and oesophageal pH monitoring is the standard test for measuring gastro-oesophageal and gastropharyngeal reflux. Artefacts caused by the intake of food may result in falsely positive gastropharyngeal reflux, which necessitates a manual review of 24-h pH data. The purpose of the study was to investigate ...
