BACKGROUND: Recent nutrition recommendations advocate a reduction in protein from animal sources (pork, beef) because of environmental concerns. Instead, protein from vegetable sources (beans, peas) should be increased. However, little is known about the effect of these vegetable protein sources on appetite regulation. OBJECTIVE: To examine whether meals based on vegetable protein sources (beans/peas) are comparable to meals based on animal protein sources (veal/pork) regarding meal-induced appetite sensations...

There is a need of an economical, reliable, and valid instrument in the German-speaking countries to measure the burden of relatives who care for mentally ill persons. We translated the Burden Assessment Scale (BAS) and conducted a study investigating factor structure, psychometric quality and predictive validity. We used confirmative factor analyses (CFA, maximum-likelihood method) to examine the dimensionality of the German BAS in a sample of 215 relatives (72% women; M = 32 years, SD = 14, range: 18 to 77; 39% employed) of mentally ill persons (50% (ex-)partner or (best) friend; M = 32 years, SD = 13, range 8 to 64; main complaints were depression and/or anxiety)...

This article aims to shed light on the self-perceptions of people with eating disorders in Malta and Italy through a deep understanding of their narratives. In contrast to the biomedical perception of the phenomenon and in opposition with the prevalent feminist theories on the subject, I consider eating disorders as the result of self-transformative processes. I suggest that anorexics, bulimics and binge eaters are actively and deliberately engaged in a project of moral self-transformation that is culturally defined...

Reducing the glycemic load (GL) of the diet may benefit appetite control but its utility is complicated by psychological influences on eating. Disinhibited behaviour, a risk factor for overconsumption, is characterized by reduced prefrontal cortex activity, which in turn modulates vagal tone; a phenomenon associated with glucoregulation. This double blind randomised controlled trial explored for the first time the influence of disinhibited eating and vagal tone (heart rate variability (HRV)) on hunger and the postprandial response to GL...

Research examining the relationship between breastfeeding and infant weight has generated conflicting results. Few studies account for significant covariates and many suffer methodological problems such as retrospective self-report. The current study aimed to investigate relationships between breastfeeding duration, infant weight and eating and positive maternal mealtime behaviours, whilst overcoming many of the limitations of previous research. Eighty-one women on low-risk maternity units gave informed consent and were visited at home at 1-week, 1-, 6- and 12-months postpartum...

Food restriction has been reported to reduce anxiety-like behavior in male rats, while the effects of food restriction on anxiety in female rats are less clear. Ghrelin is a peptide hormone produced and secreted in the stomach that stimulates food intake and is believed to play a role in reward and emotional responses like fear expression. Under food restriction endogenous ghrelin levels increase. Here, we examined the effect of moderate food restriction (80% of ad-libitum fed weight), with or without an acute application of a small dose of exogenous ghrelin intended to cause an immediate hunger response, on the expression of the acoustic startle reflex (ASR)...

(29)Si{(27)Al} TRAPDOR MAS NMR was applied to two faujasite-type zeolites with Si/Al ratios of 1.3 (Na-X) and 2.7 (Na-Y). The aim of this test study is to show that different Q(4)(mAl) sites (m =4, 3, 2, 1) can be distinguished by differently strong TRAPDOR effects (ΔS/S0). Indeed, it was found that the TRAPDOR effect depends on the number m of AlO4 units connected to the Q(4) silicon tetrahedrons. For Na-X, the measured ΔS/S0 values are 1 : 0.81 : 0.56 for Q(4)(4Al), Q(4)(3Al) and Q(4)(2Al), respectively (normalized to Q(4)(4Al))...

BACKGROUND: The first policy action outlined in the Sustainable Development Goals (SDGs) is the implementation of national social protection systems. This study assesses whether social protection provision can impact 17 indicators of five key health-related SDG goals amongst adolescents in South Africa. METHODS: We conducted a longitudinal survey of adolescents (10-18 years) between 2009 and 2012. Census areas were randomly selected in two urban and two rural health districts in two South African provinces, including all homes with a resident adolescent...

Objective: Social factors have a powerful influence on people's food intake but people typically fail to acknowledge the influence of such external cues, instead explaining their food intake in terms of factors such as how hungry they are. We examined whether the tendency to explain one's food intake in terms of internal cues (i.e., hunger) rather than external cues (i.e., other people's behavior) would be apparent when those cues are in conflict with one another. Method: Female participants (n = 104) took part in a pizza taste test after having been food deprived for 18-hr or after consuming a meal-replacement preload...

BACKGROUND: Middle-aged women are at risk of weight gain and associated comorbidities. Deliberate restriction of food intake (dieting) produces short-term weight loss but is largely unsuccessful for long-term weight management. Two promising approaches for the prevention of weight gain are intuitive eating (ie, eating in accordance with hunger and satiety signals) and the development of greater psychological flexibility (ie, the aim of acceptance and commitment therapy [ACT]). OBJECTIVES: This pilot study investigated the usage, acceptability, and feasibility of "Mind, Body, Food," a Web-based weight gain prevention intervention prototype that teaches intuitive eating and psychological flexibility skills...

The effect of fasting prior to morning exercise on 24-hour energy intake was examined using a randomized, counterbalanced design. Participants (12 active, white males, 20.8 ± 3.0 years old, VO2max: 59.1 ± 5.7 mL/kg/min) fasted (NoBK) or received breakfast (BK) and then ran for 60 minutes at 60%  VO2max. All food was weighed and measured for 24 hours. Measures of blood glucose and hunger were collected at 5 time points. Respiratory quotient (RQ) was measured during exercise. Generalized linear mixed models and paired sample t-tests examined differences between the conditions...

Food insecurity is a global issue that arises owing to systemic socioeconomic inequities and environmental constraints. To highlight the existence and the extent of food insecurity and food waste, the Orange County Health Department in Orange County, California, created a coalition called "Waste Not Orange County." Orange County is the sixth most populous county in California and has the highest median income, yet 11.4% of those residing in Orange County are food insecure, and 24.0% live in poverty. The overall vision of the coalition is to mitigate hunger in Orange County by educating the community about food donations, identifying food-insecure individuals, and connecting those individuals to sources of food...

Ibogaine is a natural chemical compound, which belongs to the indole alkaloid family. It can be naturally found within the root bark of african plant Tabernanthe iboga. Ibogaine plays a significant role among tribal cultures. Ibogaine, in small amount, causes reduction of hunger, thirst and exhaustion. In bigger amount, however, it can cause intensive visions. Other effects include reduction or complete disappearance of absitnence symptoms visible in people addicted to the nicotine, alcohol, methamphetamine, cocaine or opioids, what has been scientifically proven after the tests on animals and small groups of people...

Pairing an odor and taste can change ratings of the odor's perceptual and hedonic characteristics. Behavioral indices of such changes are lacking and here we measured sniffing to assess learned changes in odor liking due to pairing with sweet and bitter tastes. Participants were divided on their liking for sweetness, as well as dietary disinhibition (Three-Factor Eating Questionnaire-Disinhibition scale [TFEQ-D]), both of which influence hedonic odor-taste learning. In sweet likers, both sniff duration and peak amplitude increased for the sweet-paired odor...

Studies conducted in monozygotic and dizygotic twins have established a strong genetic component in eating behavior. Rare mutations and common variants of the melanocortin 4 receptor (MC4R) gene have been linked to obesity and eating behavior scores. However, few studies have assessed common variants in MC4R gene with the rewarding value of food in children. The objective of the study was to evaluate the association between the MC4R rs17782313 polymorphism with homeostatic and non-homeostatic eating behavior patterns in Chileans children...

Nutrition claims may help people to adopt healthier eating habits, but little is known about the potential cognitive effects of such claims on appetite sensations. The main purpose of this study was to evaluate the impact of nutrition claims and individual factors on perceived appetite sensations. According to a three ("healthy" versus "diet" (i.e., satiating) versus "hedonic") by two (restrained or not restrained) by two (normal-weight or overweight/obese) by two (men versus women) factorial design, 164 males and 188 females aged 18-65 were invited to taste an oatmeal-raisin snack in a blinded and ad libitum context...

Building upon the growing interest and research on genetically modified (GM) biofortification, its socioeconomic potential has been increasingly examined. We conducted two systematic reviews and meta-analyses to provide comprehensive evidence of consumers' willingness to pay (11 economic valuation studies, 64 estimates) and cost-effectiveness/benefits (five economic evaluation studies, 30 estimates). Worldwide, consumers were willing to pay 23.9% more for GM biofortified food crops. Aside from crop and design-related differences, information provision was deemed crucial...

Exercise-induced changes in appetite-regulating hormones may be intensity-dependent, however a clear dose-response relationship has not been established. The purpose of this study was to examine changes in anorexigenic markers (total PYY and GLP-1) in response to rest or exercise at submaximal and supramaximal intensities. Ten active males completed four experimental sessions in randomized order: 1) Moderate intensity continuous training (MICT; 30 min cycling at 65% VO2max); 2) High intensity continuous training (HICT; 30 min cycling at 85% VO2max); 3) Sprint interval training (SIT; 6 × 30 s "all-out" cycling bouts with 4 min recovery periods); 4) Control (CTRL; no exercise)...

Subjective responses to meals are altered by shortened sleep time and anxiety state, but this effect has been poorly studied in shift workers - who act as a typical model concerning sleep restriction and present high levels of anxiety. The objective of this study was to compare subjective perceptions of meals and the levels of anxiety in the same subjects after working night shifts and after taking a nocturnal sleep, and to investigate associations between the responses to meals and the levels of anxiety under these two conditions...
