Background/Objectives: Creatine monohydrate supplementation has gained popularity in the fitness industry due to its ability to enhance athletic performance and has sparked curiosity about other possible effects of the supplement. The purpose of this study was to examine the effect of creatine supplementation on spatial working memory, body weight, and food intake in male and female rats. Methods: Experimental rats, six male and six female, were administered creatine while six male and six female rats served as controls. The Morris water maze (MWM) was employed to assess spatial working memory. Body weight and food intake were measured daily. Results: Neither male control nor experimental animals demonstrated positive working memory upon initial exposure (week 1) to the MWM, whereas the initial exposure of female control and experimental animals resulted in positive working memory. By week 2 of the experimental period, all animals in both the control and experimental groups showed significant working memory with no significant differences among the groups. These effects were unrelated to creatine supplementation. Gender-specific differences were found for body weight, with higher weight gain observed in male rats compared to female rats. Weight gain was not directly influenced by creatine supplementation; however, food intake was lower in the experimental male rats receiving the supplement as compared to the control rats. No difference was observed in female rats. Conclusions: Because of the popularity of creatine, further research about the effects of this supplement on different mechanisms in the body influencing cognitive processing and appetitive behavior is warranted.

Long a thermodynamic curiosity, supercritical fluids (SCFs) have gradually gained ground in today’s life, generating an increasing number of new, efficient processes in diverse industrial sectors and fueling active R&D programs. Indeed, the versatility of SCFs allows them to serve a wide variety of applications. The list includes not only food processing, biofuel production, extraction of biomolecules marketable as medicines, cosmetics and nutraceuticals, but also emerging technologies for the production of electrical power, based on supercritical or transcritical thermodynamic cycles. This jointly authored article will provide a review of important applications covered by our laboratories in the agri-food, chemical and energy sectors. We will then try to detect recent trends and outline future prospects. Full article

Although edible insects (EIs) are encouraged as a sustainable source of protein, their consumption is not as generalised as other types of food that are internationally accepted. While in some regions of the world, EIs are part of the gastronomic and cultural traditions, in other regions, people are not so receptive to this type of food, and some people even express some disgust towards it. Hence, this research focused on the habits of the participants regarding the consumption of insects as well as their perceptions about EIs being or not a part of the local culture or gastronomic patrimony. A questionnaire survey was implemented in fourteen countries (Brazil, Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey), and globally, 7222 adult participants responded to the questionnaire. SPSS software (version 28) was used to process the data and carry out chi-square tests and Factor Analyses (FA). The obtained results showed significant differences between countries for all the questions included in the survey, either those regarding the habits of the participants or their opinions about the facts linked with EI tradition or cultural aspects. It was found that participants from Mexico consume EIs more than in all other countries and that strong motivations that would lead to consumption among those who do not consume include curiosity and food shortage. The solution obtained with FA considering the ten statements of the scale consisted of two factors: F1—Culture and Tradition of EIs (α = 0.675) and F2—Acceptance of EIs (α = 0.614). In conclusion, the consumption of EIs and the perceptions of people are highly variable according to geographic location and cultural environment. Full article

The truffle is a niche, valuable and ecological product exported and consumed all over the world. However, little is known about consumers’ preferences for truffles and truffle products. This study empirically explores the factors influencing their consumption in Italy. A PLS-SEM model was implemented and validated using an extended version of the theory of planned behavior, including consumers’ food-specific curiosity as an additional construct to basic constructs such as attitude, subjective norms and perceived behavioral control. The analysis allowed us to examine and verify the significance of the relationships between the factors and what impact they have on intentions to consume fresh and truffle-based products. The processing concerns of consumers were reached through face-to-face consultation with a semi-structured questionnaire. The results obtained suggested that consumers’ intentions in using truffles involve several factors, such as consumers’ personal experiences, organoleptic characteristics (aroma and taste), food safety, trust in the seller/brand, traceability information, the aspect of green products and, more generally, the protection of the environment and forests. The findings provided novel insights for researchers to understand the aspects of truffle consumption, and also represent a guideline for marketers to develop appropriate marketing tactics to grow the truffle business.

(1) Background: Exploring the drivers of organic food consumption is crucial for designing pro-environmental marketing strategies. This study aims to investigate elements associated with organic product consumption in North Portugal, with a particular focus on food sustainability. (2) Methods: A self-reported questionnaire was administered to 295 participants to examine (1) personal motivations, such as beliefs about the impact of consuming organic products on health, concerns about soil, and self-perception of control; (2) attitudes towards contextual motivations, including the value of time, price, labels, and taste; and (3) the frequency of organic product consumption. A partial least squares model was employed to explore the relationship between participants’ motivations and behavior. (3) Results: Perceiving organic food as healthy was positively associated with higher organic product consumption. Positive attitudes towards cost-effective products, spending less time purchasing products, and a high locus of control did not moderate this relationship. While soil concerns were not significantly associated with the consumption of organic products overall, this association was significant in participants with a higher locus of control. A low locus of control was associated with a positive attitude towards pesticides. (4) Conclusions: The findings suggest that bridging the gap between concerns about soil conditions and pro-environmental behavior involves perceiving oneself as an agent of change and becoming proactive at an individual level. Resources to enhance individuals’ environmental curiosity and literacy may increase their locus of control, fostering a more accurate attitude towards pesticides and, consequently, an increase in organic product consumption. Additionally, companies could strengthen the association between organic food and better health by investing in marketing. These strategies have the potential to positively impact food sustainability. Full article

In highly developed countries, more and more people use culinary services. Cooking at home, for the family, is giving way to culinary services. Consumers either order food home or use the offers of restaurants and bars. Consumers’ choice of culinary form may be influenced by cooking television programs. Many TV stations broadcast cooking programs. This study examined the impact of television culinary programs on consumer behavior in the restaurant services market. The article examines the interplay of emotional responses, personality traits, and culinary preferences to understand how TV cooking programs influence dining decisions. The study was conducted using the CAWI method, which involved 742 respondents. The study, conducted between May 2021 and April 2022, was addressed to people who visited restaurants presented in the Polish culinary TV show titled “Kitchen Revolutions”. The study revealed that almost 3/4 of the respondents chose restaurants based on the program’s recommendations. Although there was a strong emotional connection with this program—nearly half of the respondents expressed delight in the taste of snacks and main courses—this did not always translate into an increased frequency of eating meals away from home. Only every third respondent said that the program influenced their gastronomic behavior. The research hypotheses examined the extent to which culinary TV shows influence the frequency of visits to restaurants, the perceived quality of life, and the influence on consumers with specific personality traits. The results partially supported the hypothesis that cooking programs on television encourage people to eat out more often, but the perceived impact on quality of life and on some personality traits was less clear. The article contributes to the understanding of consumer behavior in the food service market by highlighting the complex dynamics of emotional reactions, personality traits, and the impact of culinary television programs. The findings have practical implications for the restaurant industry, suggesting a focus on emotional impact, food quality and presentation, and targeting marketing strategies towards consumers who are open to new experiences and ready to experiment.

Maternal obesity and gestational diabetes predispose the next generation to metabolic disturbances. Moreover, the lactation phase also stands as a critical phase for metabolic programming. Nevertheless, the precise mechanisms originating these changes remain unclear. Here, we investigate the consequences of a maternal lipid-rich diet during gestation and lactation and its impact on metabolism and behavior in the offspring. Two experimental groups of Wistar female rats were used: a control group (NC) that was fed a standard diet during the gestation and lactation periods and an overnutrition group that was fed a high-fat diet (HF, 60% lipid-rich) during the same phases. The offspring were analyzed at postnatal days 21 and 28 and at 2 months old (PD21, PD28, and PD60) for their metabolic profiles (weight, fasting glycemia insulin sensitivity, and glucose tolerance) and euthanized for brain collection to evaluate metabolism and inflammation in the hypothalamus, hippocampus, and prefrontal cortex using Western blot markers of synaptic dynamics. At 2 months old, behavioral tests for anxiety, stress, cognition, and food habits were conducted. We observed that the female offspring born from HF mothers exhibited increased weight gain and decreased glucose tolerance that attenuated with age. In the offspring males, weight gain increased at P21 and worsened with age, while glucose tolerance remained unchanged. The offspring of the HF mothers exhibited elevated levels of anxiety and stress during behavioral tests, displaying decreased predisposition for curiosity compared to the NC group. In addition, the offspring from mothers with HF showed increased food consumption and a lower tendency towards food-related aggression. We conclude that exposure to an HF diet during pregnancy and lactation induces dysmetabolism in the offspring and is accompanied by heightened stress and anxiety. There was sexual dimorphism in the metabolic traits but not behavioral phenotypes. Full article

This study analyzes the attitudes and perceptions of Romanian individuals regarding entomophagy, which is the practice of eating insects, with the explicit purpose of finding out the factors that influence acceptance and hesitancy using a questionnaire with 470 respondents. The study tackles various issues related to insect consumption, current eating habits, shopping habits, culture and tradition, the willingness and curiosity to try new foods, nutritional aspects, environment, knowledge about current events, and sustainability. The acceptance of insects as food, although studied more and more in the last few years, still has more questions than answers. Neophobia is part of the explanation, but so are the cultural determinants. The people who make the decisions could be an important matter, so targeting the decision makers with specific campaigns could make them more open to try new foods. Out of the factors that influence food choices, the top three answers were: taste, whether the food is perceived as healthy or not, and the price, so palatability is the most important aspect. Knowledge is another key factor that has to be improved, as most respondents do not have proper information about the benefits or the positive aspects of eating insects. Full article

Milk is an important dairy product in U.S. food retail. Lifestyle changes toward climate-conscious consumption, animal welfare, and food safety concerns have increased the popularity of plant-based milk alternatives. This study is focused on such beverages and provides insights and best practice recommendations for marketing managers in the U.S. food retail sector. An online survey was distributed to explore factors explaining the intentions of U.S. consumers to purchase and pay a premium for plant-based milk alternatives. Food curiosity and food price inflation were identified as relevant for both willingness to buy and willingness to pay a price premium. In addition, animal welfare concerns and the green and clean product image of plant-based alternatives were relevant to the willingness to pay a premium for plant-based milk. Full article

The role that insects will play in a healthier and more sustainable diet has been highlighted in the last years, at the European level. In future, due to environmental concerns and population growth, eating insects might be a solution for many problems. However, populations without the tradition of eating insects are still reluctant in accepting such a food as part of their diet. The present observational study highlights some factors that are influencing the acceptance of insects as food in Romania, in 2022. A number of 496 Romanian adults, 433 women and 63 men, with the mean age 39.3 ± 11 years, completed a validated questionnaire analyzing food behaviors, as well as attitudes and knowledge in relation to insects, including sustainability, nutrition and food safety aspects. Only 6.3% of participants had already eaten insects, while 43.8% claimed their openness to do it in future. Insect-based products were accepted more than insects that can be perceived as such. The most frequent words associated with insects were rather deleterious: disgust, odd, nausea, not to eat, or curiosity. Investigating the factors involved in insect acceptability in Romanians’ diets, we found a statistically significant correlation between openness to eat them and the knowledge about insects as being a valuable, sustainable and safe source of nutrients. Targeted education seems to be an important tool in accepting them as part of future diets. Full article

Excessive consumption of caffeine negatively affects individuals’ health. Therefore, we studied the use of energy drinks and the conditions associated with it among Japanese secondary school students. Participants were 236 students in grades 7–9 who completed anonymous questionnaires at home in July 2018. We measured the basic attributes and dietary, sleeping, and exercise habits. We used Chi-squared tests to compare differences between users and non-users of energy drinks. Logistic regression analyses were used to elucidate the complex association between the variables. The results showed that boys were more willing to consume energy drinks than girls. The reasons were ‘feeling fatigued’, ‘needing to stay awake’, ‘for curiosity’, and ‘to quench one’s thirst’. Among boys, the following were associated with the use of EDs. Buying their own snacks , not understanding nutritional labels on foods, high caffeinated beverage intake, late bed-times on weekdays, always waking up at about the same time, and weight. Health guidance is needed to prevent overconsumption and dependence on energy drinks. The cooperation of parents and teachers is needed to achieve these goals. Full article

In 2021, an unprecedented major movement of Asian elephants in China aroused the curiosity of hundreds of millions of people around the world. For research objectives, we firstly reproduce the movement route of Asian elephants and reveal their geographical spatial characteristics and landscape characteristics using multisource data; secondly, we reveal the reason for this Asian elephant movement. We found Asian elephants went far beyond the northernmost movement boundary from past years. Most of the areas along the movement route fell within the higher accessibility to road traffic. Over the past 20 years, the rubber and tea areas of Xishuangbanna and Pu’er have increased by 91.1% and 120.1%, respectively, from 2005 to 2019. Asian elephants spent 18 days in areas with suitable food, but relatively low vegetation coverage. The 2021 movement was most likely a “purposeful” trip rather than a “detour”. The elephants chose the most rewarding way to move forward, which showed they are far smarter than we thought. They may have left to find food due to exhausted food supply. The expansion of rubber and tea plantations has caused the habitat of Asian elephants to shrink, which was one of the reasons for the northward movement of them. Full article

Fungi-based food is expected to contribute to more sustainable food systems. The present study has three focus areas: (i) aspects that affect food choices food in daily life, (ii) aspects that affect choices of fungi-based food in particular, and (iii) drivers that motivate, and barriers that prevent, engagement in cultivating fungi and cooking fungi-based food at home. One hundred and sixty participants, who were recruited using convenience sampling, filled out qualitative questionnaires. The results show that there are numerous aspects (e.g., environmental benefits, nutrition, sensory characteristics, production practices and ingredients) that are important when people choose food in daily life. In addition to curiosity, many of these aspects also affect the choice of fungi-based food. The study identified more drivers (e.g., self-providing, curiosity, awareness of ingredients) than barriers (time, knowledge, concerns about contamination) to cultivation and cooking of fungi-based food at home. The findings are relevant for the development of fungi-based food so that this type of food is engaged with, and so that it can contribute to more sustainable food systems. Full article

In recent years, edible insects have been suggested as an alternative food that is more sustainable compared with other sources of animal protein. However, knowledge about the sustainability aspects associated with this source of food may play a role in convincing consumers to adopt insects as part of their diet. In this context, the present study investigated the level of knowledge about the sustainability of edible insects in a group of people originating from 14 countries, with some naturally entomophagous and others not. To measure the knowledge, 11 items were selected and the scores obtained were tested with statistical tools (t-test for independent samples, analysis of variance—ANOVA) to search for differences according to sociodemographic and socioeconomic characteristics, geographical origin, and consumption habits of edible insects. The obtained results showed that, in general, knowledge is moderate, with the values of the average scores for the 11 items investigated ranging from 0.23 ± 0.99 to 0.66 ± 1.02, on a scale ranging from −2 (=very low knowledge) to 2 (=very high knowledge). The highest scores were found for items relating to the lower use of animal feed and lower emission of greenhouse gases required for the production of insects compared with beef. When investigating the differences between groups of participants, significant differences were generally found, revealing a trend for higher knowledge among males and young adults, for participants residing in urban areas and in countries such as Spain, Mexico, and Poland, and for participants with higher education levels and higher incomes. When testing the influence of consumption variables on the level of knowledge, the results showed a higher knowledge for participants who had already consumed insects or are willing to consume them. Finally, it was observed that higher knowledge was found for participants whose motivation to consume insects related to curiosity, a wish to preserve the planet, the gastronomic characteristics of insects, and their nutritional value. In conclusion, these results clearly indicate a very marked influence of a number of variables on the knowledge about the sustainability of edible insects, and this may be helpful to delineate strategies to effectively raise knowledge and eventually increase the willingness to consider insects as a more sustainable alternative to partially replace other protein foods, even in countries where this is a not a traditional practice.

Although insects have long been part of the human diet in many countries, they are poorly received and accepted in European and North American countries. Therefore, this cross-sectional observational study, based on a structured questionnaire, aimed to evaluate the level of acceptability of entomophagy among young adults in a Swiss university context. The variable “acceptability of consuming insects” (ACI) was calculated according to the perception of entomophagy of each participant. The ACI was related to various socio-demographic and behavioral aspects. A total of 290 responses were validated and analyzed. The mean ACI score was 3.7 out of 6.0 (SD 1.1). Most participants responded that the most likely reason for eating insect foods was curiosity. The most common reason for not eating such foods was disgust. None of the socio-demographic variables showed a significant association with ACI. Generally, participants in this study showed a potential interest in entomophagy—on a theoretical level, as measured here by the ACI. In practice, however, there are still barriers, including disgust, which contribute to the low consumption of these foods, at least in Switzerland. Full article
