Plant-based meat analogues (PBMAs) are positioned as promising alternatives to animal-based foods due to their potential environmental and health benefits. This study aimed to investigate the acceptability of PBMAs among trend-sensitive Swedish consumers, including both those who already eat PBMAs and those who do not. A questionnaire with both closed and open-ended questions was distributed digitally via social media using convenience/snowball sampling (n = 291). Data were analyzed using descriptive statistics, chi-square tests, and qualitative content analysis. The results show that PBMA consumption was significantly more common among women, urban dwellers, and individuals identifying as flexitarians or vegetarians. Environmental concerns and animal welfare were the most important motivators for PBMA consumption, whereas non-consumers cited issues such as imported ingredients, high processing levels, and poor sensory qualities as barriers. Consumers valued flavor and visual appeal more than production or nutritional attributes. Interestingly, while current PBMA consumers did not seek meat-like sensory properties, non-consumers and potential users preferred products resembling meat in taste and texture. The name “plant-based protein” was rated most appealing, compared to alternatives like “meat analogue” or “meat substitute.” The study highlights the heterogeneity in consumer expectations and emphasizes the need for tailored product development and communication strategies. Improving sensory quality, enhancing nutritional value, and positive product naming may support a broader acceptance of PBMAs. Full article

Hybrid meat products, i.e., the combination of animal proteins with plant, microbial, algal or cultured ingredients, are becoming increasingly important as a pragmatic approach to reducing the environmental and health impact of conventional meat while retaining familiar sensory properties. This review highlights that moderate substitution rates (20–50%) can maintain or improve texture, juiciness and nutritional balance, whereas higher incorporation rates often lead to off-flavours, colour changes and texture issues. Advances in extrusion, co-processing and protein structuring have enabled increasingly sophisticated formulations. Studies show that the choice of ingredients has a strong influence on the sensory results. For example, faba beans, rice by-products or insect proteins are more acceptable at low to moderate levels, while excessive use of pulses or texturised proteins can produce beany or earthy notes. Nutritional improvements, such as more fibre and healthier fatty acid profiles, are possible but require careful optimisation. Consumer acceptance is increasing, particularly among flexitarians, but remains dependent on sensory performance, familiarity, and perceived health benefits. Ongoing obstacles include unclear regulatory requirements, high production costs and scalability issues. Future progress will require optimisation of ingredient blends, robust life cycle assessments to verify sustainability claims and transparent communication to increase consumer confidence.

Hybrid plant and meat (HPM) products, in which a portion of meat is substituted with alternative plant protein-containing ingredients, offer a promising option for flexitarian consumers seeking to increase plant protein consumption while continuing to enjoy the sensory qualities of meat products. This study evaluated the effects of faba bean protein (FBP), pea protein (PP), and rice protein (RP) ingredients at a 12.5% meat protein substitution level, under varying pre-hydration conditions and, subsequently, on the technological properties of hybrid plant/beef patties (HPBP). Colour measurements indicated that plant protein ingredient addition to HPBP resulted in increased lightness (L*) and decreased redness (a*) values. HPBP showed reduced cooking loss compared to 100% beef patties, and cooking loss increased with higher pre-hydration levels of plant proteins. Faba bean hybrid patty (FBHP) exhibited lower texture scores, while the patty containing non-hydrated RP had the highest hardness values. The texture of patties with PP was comparable to the control, irrespective of the hydration status of the plant protein. Inclusion of plant proteins also reduced water mobility by restricting intracellular water. Overall, these findings provide valuable insights into the selection of suitable plant proteins and the requirement for optimal pre-hydration of plant proteins prior to incorporation into HPBP to ensure optimal technological properties.

Understanding the components of the diet, food groups, and nutritional strategies that help prevent MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease) is essential for identifying dietary behaviors that can stop the progression of this condition, which currently affects over one-quarter of the global population. This review highlights the importance of including antioxidant nutrients in the diet, such as vitamins C and E, CoQ10, and polyphenolic compounds. It also emphasizes substances that support lipid metabolism, including choline, alpha-lipoic acid, and berberine. Among food groups, it is crucial to choose those that help prevent metabolic disturbances. Among carbohydrate-rich foods, vegetables, fruits, and high-fiber products are recommended. For protein sources, eggs, fish, and white meat are preferred. Among fat sources, plant oils and fatty fish are advised due to their content of omega-3 and omega-6 fatty acids. Various dietary strategies aimed at preventing MASLD should include elements of the Mediterranean diet or be personalized to provide anti-inflammatory compounds and substances that inhibit fat accumulation in liver cells. Other recommended dietary models include the DASH diet, the flexitarian diet, intermittent fasting, and diets that limit fructose and simple sugars. Additionally, supplementing the diet with spirulina or chlorella, berberine, probiotics, or omega-3 fatty acids, as well as drinking several cups of coffee per day, may be beneficial. Full article

Background/Objectives: A dietary pattern that simply reduces animal-based foods may be more acceptable to consumers than strict vegetarian or vegan diets. The objective of this investigation was to identify the most consistently used definitions of “flexitarian” dietary patterns, or dietary patterns with a reduced amount of animal foods. Then, sets of food-based dietary guidance (FBDG) from different countries and regions were evaluated to determine whether their guidance could accommodate flexitarian diets. Methods: Literature searches yielded 86 total results on flexitarian eating after screening by title/abstract, full text availability, and English language. Definitions of “flexitarian” were extracted from each article then reviewed and summarized. FBDGs available in English were downloaded from the Food and Agriculture Organization of the United Nations website. Guidance related to reduced animal product diets was extracted from FBDGs for eating patterns closest to 2000 kcal. Results: The summary definition of flexitarian included eating at least one animal product (dairy, eggs, meat, or fish) at least once per month but less than once per week. FBDGs from n = 42 countries or regions were downloaded and data extracted. Only FBDG from Sri Lanka explicitly describe a “semi-vegetarian” eating pattern, though n = 12 FBDGs describe a vegetarian pattern and n = 14 recommend reducing meat or animal food and/or choosing meat/dairy alternatives. Conclusions: Following a flexitarian dietary pattern in terms of reducing or limiting red meat is feasible and even implicitly recommended by the official dietary guidance of several countries. Most FBDGs examined did not include recommendations to decrease dairy or fish intake. Full article

The objective was to characterize physicochemical, nutritional, and structural properties of a novel meat-based hummus. This product was created by substituting 50% of chickpea paste with mutton. The meat-based hummus contained 0.4% sodium acid sulfate as an antimicrobial agent. The pH values of traditional hummus were greater than those of the meat-based hummus. There was no significant difference in day 0 total plate count between plant- and meat-based hummus; however, the total plate count on day 7 was significantly (p < 0.05) lower in the meat-based hummus than plant-based hummus due to antimicrobial addition. Instrumental color analysis showed greater lightness (L* values) and yellowness values for traditional hummus compared to the meat-based hummus. The meat-based hummus had 66% greater protein than traditional hummus. Scanning electron microscopy revealed a porous, gel-like structure in plant-based hummus, while meat-based hummus showed a dense, fibrous network. The flavor, creaminess, grain properties, and mouth coating scores of meat-based hummus were greater than those of traditional chickpea hummus. The study indicated that meat-based hummus can be developed by incorporating 50% cooked minced mutton. Creating innovative meat-based products like meat hummus offers the benefits of both plant-based and animal-based diets, making it a good option for flexitarians. Full article

This study is the first to examine the diet and nutritional status of the adult vegetarian and semi-vegetarian population in Serbia, using data from the EFSA EU Menu Food Consumption Survey 2017–2022. The survey included 314 participants (63 vegans, 192 lacto-ovo vegetarians, 50 pescatarians, and 9 flexitarians), aged 18–74 years (166 women and 148 men, with no gender differences in dietary patterns) across all regions of Serbia. Collected data included anthropometrics (BMI) and intake of energy, macronutrients, and specific food groups (assessed through two 24 h dietary recalls). The study revealed multiple nutritional shortcomings across all three dietary patterns. The most significant was an insufficient protein intake (especially among vegans, but also among non-vegans), connected with an unsatisfactory protein quantity, quality, and availability in plant sources. There was also a high fat intake (particularly from omega-6 and trans-fats-rich sources), especially among non-vegans (but also among vegans), while the intake of omega-3 sources was low. Non-vegans consumed less carbohydrates, fiber, vegetables, and fruit, but more sweets, beverages, and alcohol. Our findings highlight the need for improved nutritional education of vegetarians/semi-vegetarians in Serbia and the development of national food system-based guidelines for this population.

The transition to plant-based diets is advocated as a consumption measure to mitigate the environmental impacts of animal-based food production. Understanding the drivers and barriers to consumption can guide the formulation of tailored strategies for advancing plant-based alternatives in markets. This study investigated the principal drivers and barriers influencing the adoption of plant-based cheese alternatives among Danish consumers (n = 550) through an online survey. Participants were clustered based on the sensory (flavor and texture) cues using Agglomerative Hierarchical Clustering, resulting in four consumer groups: (C1) consumers who prefer plant-based cheese alternatives to closely mimic both the flavor and texture of dairy cheese (n = 172); (C2) Consumers who prefer dairy-like flavor but are open to plant-based textures (n = 141); (C3) Consumers who prefer dairy-like texture but are open to novel flavor (n = 146); and (C4) Consumers who seek variety and novelty in both flavor and texture (n = 91). The results showed that consumer preferences for flavor and texture cues are important factors in shaping their motivations and barriers toward plant-based cheese. Specifically, product availability emerged as a significant barrier for those preferring dairy-like alternatives, while sensory perception and convenience were less influential for consumers who favor novelty. Notably, the consumer clusters did not show significant statistical differences in dietary pattern types, such as omnivores, flexitarians, vegetarians, or vegans. Understanding these dynamics is essential for developing effective strategies to promote plant-based cheese alternatives and cater to varying consumer needs. Full article

Background: Several original studies have reported an inconsistent association between low meat consumption (e.g., vegetarian diets) and the risk of depression. The aim of this study was to quantify the relationship between low meat consumption and depression, identifying possible sources of heterogeneity and the potential role of psychosocial variables. Methods: A systematic review and meta-analysis were performed and reported according to PRISMA guidelines through a comprehensive search in Medline, Web of Science, Scopus, and PsychInfo databases from inception to January 2024 (PROSPERO registration ID: CRD42023405426). The exposures analyzed were (1) a meat-free diet and (2) a flexitarian (low-meat) diet. The outcome was depression. The meta-analysis included twenty longitudinal observational studies. Forest plots were designed, and heterogeneity was analyzed through I² statistic and subgroup analyses. Publication bias was assessed through funnel plots and Egger’s test. Results: The pooled overall analysis showed a protective association (HR: 0.74, 95%CI: 0.59–0.89, I² = 53.9%) between meat-free consumption and depression, which was consistent in the group of highest-quality studies. The main sources of heterogeneity identified were study quality, study design, year and country of publication, gender inequality in the country, and adjustment for certain variables (including social variables). The association between flexitarian diet and depression (HR: 0.90, 95%CI: 0.81–0.99, I² = 58.9%) was not consistent between subgroups. Conclusions: The results of this meta-analysis show a consistent protective association between meat-free diets and depression and an inconclusive association regarding flexitarian diet. Primary studies analyzing psychosocial variables are needed to explain these results. Full article

Hybrid gels combining chicken and mushroom offer innovative functional food choices, catering to the growing demand for flexitarian-friendly products. These gels reduce meat content while enhancing dietary fiber, bioactive compounds, and sustainability. This study examined the effects of split gill mushroom (Schizophyllum commune) powder (SGM) substitution (0%, 25%, 50%, and 75%, w/w) for Ligor chicken meat in hybrid gels, focusing on rheological and gelling properties. The 25% SGM gel demonstrated optimal performance in terms of rheology, texture, microstructure, pH, water-holding capacity, and color. At this level, hybrid gels exhibited superior gelation properties, demonstrating elasticity dominance, as indicated by a higher storage modulus (G′) than loss modulus (G″), along with stable cohesiveness and unaffected springiness (p > 0.05). However, hardness, gumminess, and chewiness were significantly lower than the control (p < 0.05). Higher SGM levels (50–75%) markedly weakened the gels, reducing viscoelasticity, increasing porosity and water release, and causing discoloration. These findings highlight 25% SGM as an optimal level for hybrid meat gels, maintaining product quality while promoting sustainability in the meat industry. Full article

The purpose of the present research was to deliver new knowledge of consumer expectations for plant-based (PB) alternatives to cream cheese (PBCCA) by conducting a category appraisal study. Around 1100 consumers from the United Kingdom (UK) who followed omnivore and flexitarian diets participated in an online survey. They evaluated 13 written stimuli presented as product names encompassing dairy cream cheese and PBCCAs in different flavours (original/natural, garlic/herb, salmon, strawberry, chocolate) and different product formulations (low-fat, lactose-free). A multi-response approach was used that obtained sensory, emotional, conceptual, and versatility product evaluations. The research findings, which matched predictions, showed: (1) negative product expectations for PBCCAs replicated across flavour variants, providing evidence of a systematic PB effect relative to cream cheese; (2) sensory and non-sensory drivers of expected product liking resembled those established for the cream cheese category with actual product experience; (3) sensory and non-sensory drivers of expected product versatility strongly resembled those of expected product liking; (4) groups of consumers existed with different preferences, including flavour and product type preferences (dairy, PBCCA); and (5) negative product expectations for PBCCAs translated to a stated behavioural preference for cream cheese over PBCCA, and dairy-based samples were chosen over their PB counterparts regardless of flavour. The category appraisal approach confirmed the systematic negative appeal of PBCCAs relative to their dairy counterparts. This was in line with findings from past research on other PB alternative foods and invites a rethinking of the appeal of this class of products to participants in this research, who represent a large segment of UK consumers.

Burgers have become a staple of global cuisine and can have several different versions and combinations. For example, hybrid burgers have a percentage of animal protein in their formulation, while plant-based burgers contain 100% plant-based proteins. Therefore, the aim of this study was to investigate the emerging trends and challenges in the formulation of hybrid and plant-based burgers, with an emphasis on new ingredients and the evaluation of their physical, chemical, and sensory properties. An integrative literature review on alternative burgers to meat ones was carried out, focusing on hybrid products (meat + plant-based) and fully plant-based burgers. The studies analyzed show that plant-based and hybrid burgers can be developed with different protein sources, such as soybeans, white beans, textured peas, pseudocereals, and cashew nuts, with good nutritional and sensory characteristics. While hybrid burgers combine meat and plant-based proteins to reduce saturated fats, plant-based burgers show equal promise, with a high protein and fiber content, a lower fat content, and good sensory acceptance. However, despite the market potential of these products, there are challenges to be overcome, among which are their texture and flavor, which are essential characteristics of animal-meat burgers. Another point to take into account is the diversity of preferences among consumers with different beliefs or eating styles: vegans, for example, do not prefer a product that is very similar to meat, unlike flexitarians, who seek products which are similar to animal meat in all attributes.

Background: As dietary habits shift in response to environmental concerns and health awareness, understanding healthcare professionals’ perceptions of vegan diets is crucial. Objectives: This study aimed to identify the beliefs and attitudes of primary care doctors and nurses in Spain towards vegan diets. Methods: A questionnaire-based, observational, cross-sectional study was conducted among 208 healthcare professionals. Results: 87% of participants followed an omnivorous diet, while only 3.4% identified as lacto-ovo-vegetarian (LOV) or vegan. Statistically significant differences were observed by sex, with women more likely to agree that livestock farming contributes to global warming (27.3% and 28.0% vs. 17.0% and 12.8%, respectively; p = 0.02). Additionally, women were more inclined to consider vegan diets suitable for vulnerable groups, such as pregnant women and children, when adequately supplemented (24.8% and 17.4% vs. 10.6% and 10.6%, respectively; p = 0.030). Healthcare professionals who followed a LOV or vegan diet were more likely to disagree with the notion that vegan diets do not provide the necessary macronutrients and micronutrients compared to omnivores (strongly disagree 19.9%, 56.3%, 85.7%; p = 0.001 for omnivores, flexitarians, and LOVs/vegans, respectively). Conclusions: Current nutrition training may not meet the needs of doctors and nurses. Furthermore, it is implied that some professionals’ attitudes towards vegan diets may be more influenced by personal beliefs than by scientific literature. These findings can inform future clinical guidelines and support a more evidence-based approach to dietary counselling for vegan populations. Full article

In recent decades, meat consumption has faced growing scrutiny from an environmental, health, and animal welfare perspective. As a result, reducing meat consumption has emerged as an important strategy to mitigate its negative effects. Flexitarians, a growing group of meat reducers, have attracted attention for potentially shaping future dietary trends. This study uses a qualitative approach and draws on 15 in-depth interviews with young flexitarians in Slovenia (YFS) to identify the main facilitators and barriers to meat reduction by exploring their motivations, capabilities, and opportunities as described in the COM-B behavioral model. This study fills the gap in studies on flexitarians using the COM-B model by looking at capabilities and opportunities, not solely motives. In addition, it fills the gap in qualitative in-depth studies on all three COM-B categories, as well as a gap in studies conducted outside northwest Europe and other primarily western geographical contexts. This study highlights important findings for the central and eastern European context that industry and governments should consider when developing behavior change strategies for healthy, sustainable diets. This study shows that strong rural family ties and limited access to meat alternatives are the major barriers to meat reduction in Slovenia. The YFS preferred whole, unprocessed foods (legumes, vegetables, grains) over processed meat alternatives and reduced their meat consumption primarily for health and environmental reasons, relying on social support from peers and information from popular documentaries and social media influencers.

(1) Background: Healthful plant-based diets, especially those rich in minimally processed plant-based foods such as fruits, vegetables, and whole grains, have been associated with a lower risk of diet-related chronic disease. However, individuals who limit or avoid animal products may be at risk of nutrient deficiencies, especially related to Vitamin B12, Vitamin D, omega-3 fatty acids, calcium, iron, iodine, zinc, and protein. Such deficiencies can result in both short- and long-term health challenges. We used qualitative methods to explore plant-based eaters’ knowledge and awareness of these eight nutrients of concern in diets that limit or exclude animal-source foods. (2) Methods: We conducted interviews with 28 rural flexitarian, pescatarian, vegan, or vegetarian adults in Vermont, USA. (3) Results: The participants positively viewed the healthfulness of plant-based diets, but many recognized limitations to accessing Vitamin B12, Vitamin D, and omega-3 fatty acids. They shared the strategies used to meet their needs including eating a varied diet, seeking out specific foods, and taking dietary supplements. Analyses identified gaps in the participants’ knowledge related to nutrient bioavailability, food sources of specific nutrients, and the importance of zinc and iodine. Vegans—the highest-risk group—generally presented as the most knowledgeable. The participants noted a lack of local plant-based nutrition expertise. (4) Conclusions: Addressing the identified knowledge gaps and challenges to dietary adequacy, especially among those who limit, but do not fully omit, animal-source foods, may support plant-based nutrition.
