Food neophobia is the tendency to reject or be reluctant to try new and unfamiliar foods. Due to the period of its occurrence, which falls in the years of early childhood, it can significantly affect the child’s food choices, shape taste preferences, and significantly influence the quality of the child’s diet. The neophobic attitude has an important evolutionary significance because it protects the individual from ingesting potentially dangerous substances. On the other hand, it fosters avoidance behaviors that can also relate to the beneficial aspects of obtaining and consuming food. Currently, the strong emphasis placed on food safety means that neophobia may be less adaptive; nevertheless, a conservative attitude toward new foods still prevails. There is a strong association between food neophobia and the diversity of a person’s diet and previous exposure to different foods. This review describes behaviors associated with food neophobia and analyzes other feeding and eating difficulties in children that should be differentiated from food neophobia. Management approaches affecting the reduction in food neophobia in children through various dietary and psychological interventions are also proposed.

Avoidant/Restrictive Food Intake Disorder (ARFID) is a relatively new disease entity in DSM-5 and ICD-11. This disorder continues to pose a diagnostic and therapeutic challenge for many professionals. This disorder can affect people of all ages. The most characteristic pattern is considered to be a lack of interest in eating or avoidance of food intake, which may result in nutritional deficiencies, weight loss or lack of expected weight gain, dependence on enteral feeding or dietary supplements, and impaired psychosocial functioning. This disorder cannot be explained by a current medical condition or co-occurring other psychiatric disorders, but if ARFID co-occurs with another disorder or illness, it necessarily requires extended diagnosis. Its treatment depends on the severity of the nutritional problem and may include hospitalization with multispecialty care (pediatrician, nutritionist, psychologist, psychiatrist, neurologist). The nutritional management strategy may include, inter alia, the use of Food Chaining, and should in the initial stage of therapy be based on products considered “safe” in the patient’s assessment. The role of the dietitian in the management of a patient with ARFID is to monitor weight and height and nutritional status and analyze the foods that should be introduced into the food chain first.

Background: Emotional eating (EE) is not a separate eating disorder, but rather a type of behavior within a group of various eating behaviors that are influenced by habits, stress, emotions, and individual attitudes toward eating. The relationship between eating and emotions can be considered on two parallel levels: psychological and physiological. In the case of the psychological response, stress generates a variety of bodily responses relating to coping with stress. Objective: Therefore, the main objective of this study was to evaluate and compare the prevalence of emotional eating in groups of students in health-related and non-health-related fields in terms of their differential health behaviors—diet and physical activity levels. Material and Methods: The cross-sectional survey study included 300 individuals representing two groups of students distinguished by their fields of study—one group was in health-related fields (HRF) and the other was in non-health-related fields (NRF). The study used standardized questionnaires: the PSS-10 and TFEQ-13. Results: The gender of the subjects was as follows: women, 60.0% (174 subjects) (HRF: 47.1%, n= 82; NRF: 52.9%, n = 92); men, 40.0% (116 subjects) (HRF: 53.4%, n = 62; NRF: 46.6%, n = 54). The age of the subjects was 26 years (±2 years). Based on the results of the TFEQ-13, among 120 subjects (41.4%) there were behaviors consistent with limiting food intake (HRF: 72.4%; NRF: 11.0%), while 64 subjects (20.7%) were characterized by a lack of control over food intake (HRF: 13.8%, 20 subjects; NRF: 27.4%, 20 subjects). Emotional eating was characteristic of 106 students (37.9%), with the NRF group dominating (61.6%, n = 90). It was observed that a high PSS-10 score is mainly characteristic of individuals who exhibit EE. Conclusions: The results obtained in the study indicate that lifestyle can have a real impact on the development of emotional eating problems. Individuals who are characterized by elevated BMI values, unhealthy diets, low rates of physical activity, who underestimate meal size in terms of weight and calories, and have high-stress feelings are more likely to develop emotional eating. These results also indicate that further research in this area should be undertaken to indicate whether the relationships shown can be generalized.

Background: Social media can significantly impact body image perception among adolescents. Objective: This study examines how exposure to fitspiration content relates to body esteem, with a focus on gender differences and BMI. Methods: A cross-sectional online survey was conducted among 211 participants using validated instruments (Body Esteem Scale, A. Sobczak’s silhouette scale). Data were analyzed using descriptive statistics and chi-square tests. Results: Exposure to athletic images decreased self-esteem in 37% of participants, particularly among women (p = 0.004). Gender significantly influenced the tendency to compare oneself with athletic individuals (p = 0.02). BMI was not significantly associated with body image perception (p = 0.05). Conclusions: Gender-specific patterns in social media-related body image perception highlight the need for targeted interventions to mitigate negative impacts among young adults.

The optimal body composition for health is an individual trait and is determined by genetic factors, sex, age, somatotype, physical activity, and individual variability. The present study aims to assess how professional football players’ body composition has changed over the training macrocycle in various age groups and to determine the correlation between nutritional awareness and body composition maintenance. Thirty-eight football players participated in the study, with 16 players classified in the younger age group (19–25) and 22 in the older age group (26–31). Using the direct segmented multi-frequency electrical impedance analysis technique, the athletes’ body composition was assessed six times across a training macrocycle made up of preparatory, competitive, and transitional periods. The Sports Nutrition Knowledge Questionnaire was used to evaluate nutrition knowledge. The above correlations show that both younger and older athletes with higher awareness are better able to adjust their nutrition to meet the goals of the preparation period and can achieve greater gains in muscle mass and greater reductions in body fat. According to the study’s results, athletes who are better conscious of their nutritional needs during competition experience less muscle loss and exhibit more consistent body weight and BMI levels. Football players’ body composition suffers detrimental alterations throughout the transition period. Higher body mass, lean body mass content, and skeletal muscle mass are traits of older players. Higher nutritional knowledge reduces the negative modifications of body composition consisting of muscle mass reduction and fat gain. Nutritional knowledge influences the stability of body composition in both age groups during all the analyzed periods: Preparation, competition, and transition.

Individuals suffering from non-communicable NCDs often experience chronic pain, which can directly contribute to the development of kinesiophobia and fear of movement, significantly impacting the quality of life and physical activity (PA) of chronically ill patients. This review aims to examine the impact of kinesiophobia on PA, quality of life, and the rehabilitation process in patients with diabetes, cancer, and chronic cardiovascular and respiratory diseases. The research methodology is based on a systematic literature review using six databases (PubMed, Scopus, Web of Science, EMBASE, Cochrane Library, and Google Scholar), conducted according to PRISMA guidelines. The review included 81 articles (comprising experimental studies, meta-analyses, and systematic reviews). The prevalence of kinesiophobia and fear of movement among patients with chronic diseases ranged from 42.85% to 93%, depending on the type of condition. The average prevalence rate of kinesiophobia in the entire analyzed group was 63.6%, which highlights the significance of the problem in relation to the chronic diseases discussed. The presence of movement-related fear in individuals with chronic illnesses represents a significant barrier to engaging in PA, which can directly impact their quality of life. Future research is recommended to focus on identifying risk factors and the influence of kinesiophobia on various aspects of life, allowing for clearer understanding and coherence.
