Summary: The study found that continued consumption of milk containing A1 beta-casein after weaning can lead to increased stress-induced immobility in rats, along with an increase in specific bacteria groups in the intestines, changes in brain receptors, and alterations in urinary biochemical profiles. These results suggest that milk containing A1 beta-casein may affect mood through a gut-brain axis mechanism.

Summary: In healthy men, intragastric tryptophan increases plasma cholecystokinin levels and effectively suppresses energy intake, leading to enhanced fullness after intake. Obese men showed less response to tryptophan compared to lean men.

Summary: Intragastric Trp has potent energy intake-suppressant effects in both lean men and those with obesity, apparently related to the Trp:LNAAs ratio. In addition, postmeal, fullness was greater after Trp-3 in men with obesity.

Summary: In non-psychiatric subjects, single-dose INOT significantly reduces food intake, but no significant effects were found in patients with anorexia nervosa, bulimia nervosa, and schizophrenia. Further studies are needed to assess the long-term effects and safety of INOT in obese patients and whether it could be a treatment option for patients with eating disorders.

Summary: This study found that the gene expression of the oxytocin receptor is related to orofacial pain caused by inflammation. Inflammation can activate peptidergic neurons, and it is suggested that oxytocin modulates inflammation-induced nociception by enhancing its expression in sensory ganglion cells.

Summary: This study assessed the impact of a TRP-rich diet on the mental state and TRP metabolism of elderly individuals with mood disorders. The results showed that a TRP-rich diet improved the mental state of individuals with mood disorders and enhanced the metabolism of TRP. Therefore, a TRP-enriched diet can be considered as a component of the treatment for elderly individuals with mood disorders.

Summary: The experiment showed that increasing dietary Trp can increase hypothalamic serotonin concentration, and improvements in growth performance were observed only in pigs fed diets containing excess Leu. Increasing dietary Leu reduced growth performance and hypothalamic serotonin concentration. However, the effect of dietary Trp was more pronounced when the Leu level was at 299% SID Leu:Lys ratio compared to 101% SID Leu:Lys ratio.

Summary: An experiment was conducted to investigate whether increased dietary tryptophan (Trp) is needed in high-leucine (Leu) diets for growing pigs. The results showed that increasing dietary Trp increased hypothalamic serotonin concentration, and pigs fed diets with excess Leu only exhibited increased average daily gain and average daily feed intake. Increasing dietary Leu reduced growth performance and influenced the metabolism of several essential amino acids. However, Trp supplementation partially mitigated the negative effect of excess Leu.

Summary: Adjusting the protein content in milk formulations affects protein and energy levels, amino acid intake, and satiety. Transitioning from a 20:80 whey:casein ratio similar to animal milk to a 60:40 ratio resembling human milk impacts glucose metabolism, hormone release, appetite, and brain processes related to food intake. The shift from a 20:80 to 60:40 whey:casein ratio in milk influences short-term feeding and relevant brain processes, as evidenced in studies using laboratory mice.

Summary: This study aimed to explore the effects of environmental factors on eating behavior and food intake in toddlers. The results showed that food fussiness was more common in older children, children conceived with medical assistance, children exposed to distractions during meals, rewarded by parents to finish meals, free to eat at will, and those who ate only occasionally with the whole family. Unsatisfactory dietary diversification was not significantly associated with any variable.

Summary: The UK's aging population requires promotion of balanced nutrition, with a particular focus on increasing dietary fiber intake. Surveys involving older adults showed their willingness to learn about dietary fiber and the need for accessible information. Educational materials proved effective in engaging older adults and were perceived as useful. A holistic approach, involving support from various sources, can aid in improving dietary fiber consumption and overall health outcomes among older adults.

Summary: Overeating associated with neurogenic obesity after spinal cord injury (SCI) may be related to how persons with SCI experience satiation, their eating frequency, and the context in which they eat their meals. Those with SCI rely less on physiological satiation cues for meal termination and instead rely more on hedonic cues. There are differences in meal contexts and eating frequency between SCI individuals and controls, with SCI individuals consuming fewer meals but having a higher overall eating frequency due to increased snacking. These factors likely contribute to overeating associated with neurogenic obesity after SCI.

Summary: This study investigated the relationship between executive functions and cognition during adolescence, and the intake of fat and sugar two years later. The study found that higher impulsivity and reward-seeking behaviors were related to greater fat and sugar intake in males, while higher negative urgency and BMI were related to greater intake in both sexes. These findings suggest that individuals with certain traits may be more at risk for weight gain due to overconsumption of unhealthy foods.

Summary: The COVID-19 pandemic and associated lockdowns resulted in changes in food accessibility and availability, leading to shifts in food habits and behaviors among people worldwide. A study conducted in Australia examined the self-reported changes in food habits and behaviors of adults during the COVID-19 restrictions in 2020. The majority of respondents reported developing positive food habits, such as trying new recipes, cooking from scratch, and reducing take-away meals. The study also found that family involvement in food preparation and eating together increased during the restrictions. However, there were negative experiences, including difficulties in purchasing certain foods and limited access to food outlets.

Summary: This study aimed to assess the effect of dietary sweetness on appetite in adults with and without obesity. The results showed that the response of ghrelin to unsweetened rinses was energy-specific for all adults, while rinses containing sucralose led to greater cephalic phase cholecystokinin release in adults with a BMI between 18.5 and 24.9 kg/m(2).

Summary: This study examines the interactive effects of information and consumer trust on consumer preferences for organic food. The results show that consumers are willing to pay a higher price for organic food, especially those with higher levels of trust. The introduction of information significantly increases consumers' willingness to pay, with a greater increase observed among high-trust consumers.

Summary: This study aimed to investigate the association between sensory reactivity and feeding problems in young children. The results showed that taste/smell sensitivity was significantly associated with difficulties in texture transition/introduction, limited variety of foods, and both feeding problems. Additionally, children with total sensory reactivity or auditory filtering sensory reactivity had a higher prevalence of consuming a limited variety of foods. These findings highlight the importance of considering sensory reactivity as a potential predictor of feeding problems.
