In recent years, the trend toward plant-based beverages has continued to grow rapidly. This study aimed to assess the effects of sociodemographic characteristics and knowledge about plant-based beverages, subjective norms, perceived price, environmental protection, animal welfare, availability, and trust on attitudes and buying behavior toward these products. This study was conducted online using a two-part questionnaire prepared by considering the literature. This study included 935 participants, and our findings confirmed that the variable of environmental protection affects the attitude toward these products ($\mathsf{\beta }=$ 0.095; p = 0.007). Furthermore, gender, income level, lactose intolerance, and bloating due to cow’s or sheep’s milk influenced actual buying behavior (p < 0.05; p < 0.001). These findings indicate that people’s increased environmental protection awareness will positively influence attitudes towards plant-based beverages and that individuals who do not experience lactose intolerance and bloating due to cow’s or goat’s milk will have lower actual buying behavior. It was also determined that individuals with lower incomes bought more plant-based beverages. In conclusion, plant-based beverage marketers need to take into account individuals’ sociodemographic characteristics and environmental protection awareness when planning their marketing strategies.

The consumption of insect-based foods has been widely studied in recent years due to their nutritional value and their contribution to sustainability. In this study, the integrated sustainable neophilic insect-based eating model (ISNIEM) was used to investigate the various parameters that influence the intention of members of Turkish society to consume insect-based foods. Structural equation modeling was used to test the ISNIEM. A total of 1194 participants were reached through an online survey. According to the study data, sustainability attitudes (biospheric values, new human interdependence paradigm, attitude toward sustainability, attention to insect welfare) influence individuals’ intentions to consume insect-based foods by interacting with each other; however, intentions do not influence behavior in the same direction. As expected, food neophobia reduced the number of chosen insect-based foods (NCIBF) (β: −0.121; p < 0.001), while social norms positively influenced the NCIBF (β: 0.176; p < 0.001) and reduced food neophobia (β: −0.307; p < 0.001). Meanwhile, social norms and food neophobia did not affect the intention to eat insect-based food (p > 0.05). The findings of this study suggest that the ISNIEM may be effective in predicting individuals’ intentions and behaviors toward eating insect-based foods in Turkey.

Brain fog is a condition that is characterized by poor concentration, memory loss, decreased cognitive function, and mental fatigue. Although it is generally known as a long-term COVID-19 symptom, brain fog has also been reported to be caused by many other diseases. Thus, it is necessary to assess this condition in certain populations. This study aimed to evaluate the reliability and validity of the Brain Fog Scale in a Turkish population. We conducted the study in two phases. In a pilot study including 125 participants, we confirmed the suitability of the scale for validity analyses and then conducted exploratory (n = 230) and confirmatory factor analyses (n = 343). The Cronbach’s alpha value of the 23-item Brain Fog Scale was 0.966. In addition, the 23-item and three-factor structure was confirmed as a result of the analyses. These three factors are mental fatigue, impaired cognitive acuity, and confusion. We also found that participants previously diagnosed with COVID-19 had higher brain fog scores. This finding indicates that brain fog is an important condition that can accompany COVID-19. Furthermore, this validated construct has an acceptable fit and is a valid and useful tool for the Turkish population.

Background: Disordered eating attitudes are major public health concerns associated with adverse physical, psychological, and social outcomes. Therefore, brief, psychometrically sound screening tools are needed to identify individuals at risk early. The Eating Attitudes Test-7 (EAT-7) is a shortened screening tool developed to assess disordered eating attitudes. However, its Turkish validity and reliability have not been previously examined. Therefore, this study aimed to assess the validity and reliability of the Turkish version of the EAT-7 among Turkish-speaking adults. Methods: This methodological validation study was conducted between November 2025 and January 2026. Data were collected online using a snowball sampling technique. After a pilot study with 210 participants, the main study included 1635 adults aged ≥18 years. Exploratory factor analysis was performed with 500 participants, and confirmatory factor analysis was performed with an independent sample of 1135 participants. Internal consistency and construct validity were assessed. Convergent validity was evaluated through correlations with the EAT-26, Eating Disorder Examination Questionnaire-13 (EDE-Q-13), and Depression Anxiety Stress Scale Short Form (DASS-8). Results: The Turkish version of the EAT-7 demonstrated excellent internal consistency, with a Cronbach’s alpha coefficient of 0.925. The Kaiser–Meyer–Olkin value was 0.909, and Bartlett’s test results were significant. Exploratory factor analysis supported a single-factor structure explaining 70.133% of the total variance. Confirmatory factor analysis confirmed a good model fit. The total EAT-7 score was positively correlated with the EAT-26, EDE-Q-13, and DASS-8 scores. Conclusions: The Turkish version of the EAT-7 is a valid, reliable, brief, and practical screening tool for assessing disordered eating attitudes among Turkish-speaking adults.

This study aimed to determine the effect of adding nuts to a regular breakfast on blood glucose, insulin, and triglyceride levels, and to evaluate participants’ opinions by sex as a preliminary study for future studies. Data and biochemical parameters were collected through face-to-face interviews with Acibadem Hospital employees (n = 12) between April and September 2023. Participants consumed 30 g of nut-supplemented breakfasts for 4 weeks while maintaining their regular lifestyle. Blood tests and visual analog scale (VAS) parameters were assessed on intervention days. VAS scores indicated differences in meal taste, post-breakfast well-being, satiety, and meal adequacy, and for “feeling better after breakfast”, and “providing better satiety”, were significantly higher for the nut-supplemented breakfasts (p < 0.05), especially walnut-supplemented. Under the control of age, sex, and BMI variables in the participants, women responded better to peanut butter consumption than men in terms of blood insulin and triglyceride regulation (p < 0.05). However, triglyceride regulation in men was better managed by walnut consumption than in women. Understanding how nut-supplemented breakfasts impact blood glucose, insulin, and triglyceride levels, as well as consumer perceptions, is crucial for promoting healthier dietary choices.
