Food processing impacts both food structure and nutritional density. The effect of food structure on satiety and glycemic potentials is well recognized. However, the association between processing, satiety and glycemic potentials and nutrient profiles has not been much studied, especially in the diets of the elderly. Therefore, this study aimed at exploring relations between the level of food processing, consumption and nutrient profiles and satiety and glycemic potentials among 6686 French elderly people (≥65 years)...

Low-calorie sweeteners are considered to be beneficial in calorie control, but the impact of these sweeteners on gastric emptying is not well described. The purpose of this study was to compare the gastric emptying rate of agave nectar with those of glucose and fructose, and to evaluate the interaction of cholecystokinin (CCK)-1, CCK-2 and glucagon-like peptide-1 (GLP-1) receptors in agave-induced alterations in gastric emptying. Female Sprague-Dawley rats were fitted with gastric cannulas. Following the recovery, the gastric emptying rates of glucose, fructose and agave at 12...

Fatty acid translocase/cluster of differentiation 36 (FAT/CD36) functions as a membrane long-chain fatty acid transporter in various tissues in land animals. Not much is known about the CD36 molecule in teleost fish. Therefore, we studied CD36 in grass carp (Ctenopharyngodon idella, ciCD36). The full-length complementary DNA sequence of ciCD36 was 1976 bp, with an ORF of 468 amino acids, which had high sequence similarity to the CD36 of common carp. The messenger RNA (mRNA) expression of ciCD36 was high in the intestine, heart, liver, visceral tissue, and brain, but absent in the kidney...

KEY-POINTS: Relaxin-3 is a stress-responsive neuropeptide that acts at its cognate receptor, RXFP3, to alter behaviours including feeding. In this study, we have demonstrated a direct, RXFP3-dependent, inhibitory action of relaxin-3 on oxytocin and vasopressin PVN neuron electrical activity, a putative cellular mechanism of orexinergic actions of relaxin-3. We observed a Gαi/o -protein-dependent inhibitory influence of selective RXFP3 activation on PVN neuronal activity in vitro and demonstrated a direct action of RXFP3 activation on oxytocin and vasopressin PVN neurons, confirmed by their abundant expression of RXFP3 mRNA...

The ability to choose should let people create more enjoyable experiences. However, in a set of 5 studies, people who chose repeatedly during ongoing consumption exhibited a greater drop in enjoyment compared with those who received a series of random selections from the same set of liked stimuli. Process evidence indicated that choosing increased satiation because it triggered overall reflections on the repetitive nature of the ongoing consumption experience. Moderating evidence also supported our theoretical account as differences in satiation disappeared when nonchoosers were explicitly cued to think about repetition in the general sense, or when choosers made all of their choices before the onset of repeated consumption...

Yu Yi-Hao
Body weight is neither stationary nor changing unidirectionally. It usually oscillates up and down around a set-point. Two types of forces determine the direction of weight changes. Forces that push body weight away from the set-point are defined as non-homeostatic and are governed by multiple mechanisms, including but not limited to hedonic regulation of food intake. Forces that restore the set-point weight are defined as homeostatic, and they operate through the mechanisms that regulate short-term energy balance driven by hunger and satiation and long-term energy balance driven by changes in adiposity...

Like other cnidarians, the freshwater organism Hydra is characterized by the possession of cnidocytes (stinging cells). Most cnidocytes are located on hydra tentacles, where they are organized along with sensory cells and ganglion cells into battery complexes. The function of the battery complexes is to integrate multiple types of stimuli for the regulation of cnidocyte discharge. The molecular mechanisms controlling the discharge of cnidocytes are not yet fully understood, but it is known that discharge depends on extracellular Ca(2+) and that mechanically induced cnidocyte discharge can be enhanced by the presence of prey extracts and other chemicals...

BACKGROUND: In the United States, 17% of children are currently obese. Increasing feelings of fullness may prevent excessive energy intake, lead to better diet quality, and promote long-term maintenance of healthy weight. OBJECTIVE: The purpose of this study was to develop a fullness-rating tool (aim 1) and to determine whether a high-protein (HP), high-fiber (HF), and combined HP and HF (HPHF) breakfast increases preschoolers' feelings of fullness before (pre) and after (post) breakfast and pre-lunch, as well as their diet quality, as measured by using a composite diet quality assessment tool, the Revised Children's Diet Quality Index (aim 2)...

BACKGROUND: Attempts to model cumulative intake curves with quadratic functions have not simultaneously taken gustatory stimulation, satiation, and maximal food intake into account. OBJECTIVE: Our aim was to develop a dynamic model for cumulative intake curves that captures gustatory stimulation, satiation, and maximal food intake. DESIGN: We developed a first-principles model describing cumulative intake that universally describes gustatory stimulation, satiation, and maximal food intake using 3 key parameters: 1) the initial eating rate, 2) the effective duration of eating, and 3) the maximal food intake...

REVIEW
Peter J Rogers
This review examines the merits of 'food addiction' as an explanation of excessive eating (i.e., eating in excess of what is required to maintain a healthy body weight). It describes various apparent similarities in appetites for foods and drugs. For example, conditioned environmental cues can arouse food and drug-seeking behaviour, 'craving' is an experience reported to precede eating and drug taking, 'bingeing' is associated with both eating and drug use, and conditioned and unconditioned tolerance occurs to food and drug ingestion...

BACKGROUND: Whether gastrointestinal motor and sensory function is primary cause or secondary effect of abnormal body weight is uncertain. Moreover, studies relating continuous postprandial sensations of satiation to measurable pathology are scarce. This work assessed postprandial gastrointestinal function and concurrent sensations of satiation across a wide range of body weight and after weight change. METHODS: Patients with anorexia nervosa (AN) and obesity (OB) were investigated in reference to normal weight controls (HC)...

Food choice and food intake are guided by both sensory and metabolic processes. The senses of taste and smell play a key role in the sensory effects on choice and intake. This article provides a comprehensive overview of, and will argue for, the differential role of smell and taste for eating behavior by focusing on appetite, choice, intake, and satiation. The sense of smell mainly plays a priming role in eating behavior. It has been demonstrated that (orthonasal) odor exposure induces appetite specifically for the cued food...

BACKGROUND: Ingestion of a meal induces cognitive and hedonic sensations and our aim was to determine the relation between both dimensions. METHODS: In three groups of healthy non-obese men (n=10 per group) three types of meals with equivalent levels of palatability were tested: a liquid meal, a solid-liquid low-calorie meal, and a solid-liquid high-calorie meal. The cognitive and hedonic responses were measured on 10-cm scales before and during the 30-minute postprandial period...

SCOPE: A bolus administration of 0.15 mg nonivamide has previously been demonstrated to reduce energy intake in moderately overweight men. This 12-week intervention investigated whether a daily consumption of nonivamide in a protein-based product formulation promotes a reduction in body weight in healthy overweight subjects, and affects outcome measures associated with mechanisms regulating food intake, e.g. plasma concentrations of an-/orexigenic hormones, energy substrates as well as changes in fecal microbiota ...

PURPOSE: To determine the effect of pre-meal screen-time activities on subjective emotions, subjective appetite, and food intake (FI) in 9-14 year-old girls. METHODS: In this clinical study, 31 girls completed four 45-min treatment conditions of television viewing (TVV), video game playing (VGP), a challenging computer task (CT), and sitting without screen exposure (control) in a randomized order. Each treatment condition was followed immediately by an ad libitum pizza lunch, and FI was calculated from the weight of the consumed pizza...

Prader-Willi syndrome (PWS), the leading genetic cause of obesity, is characterized by a striking hyperphagic behavior that can lead to obesity, type-2 diabetes, cardiovascular disease and death. The molecular mechanism underlying impaired satiety in PWS is unknown. Oleoylethanolamide (OEA) is a lipid mediator involved in the control of feeding, body weight and energy metabolism. OEA produced by small-intestinal enterocytes during dietary fat digestion activates type-α peroxisome proliferator-activated receptors (PPAR-α) to trigger an afferent signal that causes satiety...

Ari Shechter, Gary J Schwartz
For the past several decades, vagal and hormonal gut-brain negative feedback signaling mechanisms that promote satiety and subsequent suppression of food intake have been explored. In addition, a separate positive feedback process termed "appetition," involving postoral signaling from the gut to the brain, has been shown to promote food intake and produce flavor-nutrient preference conditioning. Afferent fibers emerging from the vagus nerve form the main pathway by which information is relayed from the abdominal viscera to the hindbrain and eventually other higher brain regions involved in food intake...

Fish that are active foragers usually perform routine activities while digesting their food; thus, their postprandial swimming capacity and related behavior adjustments might be ecologically important. To test whether digestion affect swimming performance and the relationships of digestion with metabolism and behavior in an active forager, we investigated the postprandial metabolic response, spontaneous swimming activities, critical swimming speed (Ucrit), and fast-start escape performance of both fasted and digesting (3h after feeding to satiation) juvenile rose bitterling (Rhodeus ocellatus)...

BACKGROUND AND AIMS: The Janzen-Connell model predicts that common species suffer high seed predation from specialized natural enemies as a function of distance from parent trees, and consequently as a function of conspecific density, whereas the predator satiation hypothesis predicts that seed attack is reduced due to predator satiation at high seed densities. Pre-dispersal predation by insects was studied while seeds are still on parent trees, which represents a frequently overlooked stage in which seed predation occurs...
