It is posed that protein intake is tightly regulated by the human body. The role of sensory qualities in the satiating effects of protein, however, requires further clarification. Our objective was to determine the effect of within-meal protein content and taste on subsequent food choice and satiety. We used a cross-over design whereby sixty healthy, unrestrained subjects (twenty-three males and thirty-seven females) with a mean age of 20·8 (sd 2·1) years and a mean BMI of 21·5 (sd 1·6) kg/m2 were offered one of four isoenergetic preloads (rice meal) for lunch: two low in protein (about 7 % energy derived from protein) and two high in protein (about 25 % energy from protein). Both had a sweet and savoury version. At 30 min after preload consumption, subjects were offered an ad libitum buffet, consisting of food products differing in protein content (low/high) and taste (sweet/savoury). In addition, the computerised Leeds Food Preference Questionnaire (LFPQ) was run to assess several components of food reward. The results showed no effect of protein content of the preloads on subsequent food choice. There was an effect of taste; after eating the savoury preloads, choice and intake of sweet products were higher than of savoury products. No such preference was seen after the sweet preloads. No differences in satiety were observed. To conclude, within one eating episode, within-meal protein content in these quantities seems not to have an effect on subsequent food choice. This appears to be mostly determined by taste, whereby savoury taste exerts the strongest modulating effect. The results of the LFPQ provided insight into underlying processes.

The role of stress, trauma, and adversity particularly early in life has been identified as a contributing factor in both drug and food addictions. While links between traumatic stress and substance use disorders are well documented, the pathways to food addiction and obesity are less established. This review focuses on psychosocial and neurobiological factors that may increase risk for addiction-like behaviors and ultimately increase BMI over the lifespan. Early childhood and adolescent adversity can induce long-lasting alterations in the glucocorticoid and dopamine systems that lead to increased addiction vulnerability later in life. Allostatic load, the hypothalamic-pituitary-adrenal axis, and emerging data on epigenetics in the context of biological embedding are highlighted. A conceptual model for food addiction is proposed, which integrates data on the biological embedding of adversity as well as upstream psychological, social, and environmental factors. Dietary restraint as a feature of disordered eating is discussed as an important contextual factor related to food addiction. Discussion of various public health and policy considerations are based on the concept that improved knowledge of biopsychosocial mechanisms contributing to food addiction may decrease stigma associated with obesity and disordered eating behavior.

ObjectiveIncreasing prevalence of obesity in the world and increasing role of processed foods in daily life has led to become the focal point of food addiction. This study aims to investigation of food addiction and impulsivity relations biological rhythms differences and insomnia in university students.MethodOne thousand and five hundred students planned to participate who studies in Konya Selcuk University central campus. Participants were to fill out the test during their classes under physician supervision. The volunteers completed a package of psychological instruments including the Morningness–Eveningness Questionnaire, Yale Food Addiction Scale, Insomnia Severity Index, and Barratt Impulsiveness Scale administered by two investigators in their classrooms.ResultsIn total, 1323 forms were suitable for statistical analysis. The mean age was 20.83, mean BMI was 22.02. Food addiction prevalence was 18.2%. Our study showed that association between the eveningness type and food addiction (P < 0.045). Also, the eveningness type and insomnia were in positive correlation in impulsivity (P < 0.001).ConclusionThis study has explored the association between eveningness type of biological rhythms, food addiction, insomnia and impulsivity.Disclosure of interestThe authors have not supplied their declaration of competing interest.
