The research objectives were to: (1) examine the relationship among motivations, satisfaction and loyalty with plant-based food dining at destinations; (2) determine if and how the attractiveness of eating plant-based foods moderates satisfaction and loyalty; and (3) investigate potential differences in visitor background information and consumption characteristics.

A survey was conducted at tourist attractions in southern Taiwan and 274 valid questionnaires were obtained. The relationships among motivations, satisfaction and loyalty were investigated when eating plant-based foods during travel. The moderating effects of food attractiveness on motivations and satisfaction/loyalty were measured.

The results indicated a positive relationship between motivations and satisfaction/loyalty in plant-based food dining. Motivations for plant-based food dining were comprised of four domains (physical, cultural, interpersonal and prestige) and satisfaction and loyalty had three (overall satisfaction, intention to revisit and intention to recommend).

The major implications were that motivations had a significant effect on satisfaction and loyalty; food attractiveness did not moderate the effect of motivations on satisfaction/loyalty; and background characteristics influenced satisfaction and loyalty.

Marketers and strategic planners for plant-based restaurants or those with plant-based meal options must make a greater effort to understand the distinctive demographic and dietary characteristics of the people who comprise the core of this market.

This research adds to the very limited literature on plant-based and vegetarian dining in tourism destinations. Furthermore, it tests, partially validates and expands a model by Kim et al. (2009) for consuming local food while traveling. The findings also complement the considerable evidence linking motivations to satisfaction and loyalty when dining.

Cataract, or lens opacification, is a major public health burden accounting for more than half of all blindness worldwide. Plant-based dietary indices provide a unique approach to investigating a modifiable risk for age-related cataracts (ARC). The purpose of this study was to investigate the association between plant-based diet indices and risk of ARC.

This case-control study was conducted on 97 patients with newly diagnosed ARC and 198 healthy people (as a control group) in Iran. Convenience sampling and a food frequency questionnaire were used. Three plant-based dietary indices were used based on the health promoting qualities of food items, the overall plant-based diet index (PDI), healthful plant-based diet index (H-PDI) and unhealthful plant-based diet index (U-PDI) which comprised refined carbohydrates and highly processed foods. The plant-based dietary indices were used to investigate relationships with risk of ARC.

After adjusting for potential covariates, no significant association between a higher adherence to O-PDI and risk of ARC. As well, a higher adherence to H-PDI was inversely associated with the risk of ARC (OR = 0.35,95%CI:0.16–0.78). In contrast, there was a significant positive association between a higher adherence to U-PDI and the risk of ARC (OR = 3.67,95%CI:1.66 – 8.15).

The findings of this study have underscored the potential impact of the quality of plant-based food selections on the likelihood of developing ARC. Therefore, adopting a plant-based diet that is rich in nutrient-dense plant-based foods while being low in unhealthy options may have the potential to reduce the risk of ARC.

This was an explorative study, the purpose of which was to understand how Chinese flexitarians were motivated to reduce their animal-based food consumption and specifically to explore why and what was behind these changes. Further, this study provides insights into how a transition towards a more plant-based diet might occur.

This study conducted 30 in-depth online interviews with Chinese flexitarians from two major Chinese cities. Interview transcripts were analysed through the lens of the Food Choice Process Model.

Participants adopted flexitarian diets due to health (n = 22), sustainability (n = 5) or ethical (n = 3) concerns. Many participants stated that they still enjoyed animal-sourced foods, were uncomfortable talking about their dietary transition and needed more social support. Consequently, most participants were unlikely to progress to vegetarian or vegan diets. While there are some commonalities between these findings and the results of similar studies with Western consumers, the many culturally and context-specific results revealed herein make an important contribution to the sustainability literature.

This is the first study exploring Chinese consumers’ flexitarianism experiences. These findings can be used by the food industry and interested business actors to improve communication and promotional strategies that encourage consumers to make healthier and more sustainable food choices.

Amidst pressing environmental concerns, the service industry has increased its focus on sustainable production and consumption patterns. This study aims to explore whether Generation Z’s perceived value of plant-based food influences feelings of guilt as a result of consuming meat instead of plant-based food and/or pride from consuming plant-based foods, which might then lead to decisions to purchase alternative plant-based products at restaurants.

A survey was conducted measuring a range of variables and their relationships. The hypothesized model was tested using covariance-based structural equation modeling.

Results showed that perceived social value significantly influenced guilt and pride with perceived emotional value only influencing pride. Both guilt and pride significantly influenced the decision to switch eating patterns from conventional meat to plant-based protein at restaurants. And, finally, environmental concern significantly moderated the effect of emotional value on guilt.

To achieve sustainable goals, food producers should promote plant-based menu items by increasing the awareness of social approval through marketing communications.

This study bridges a gap in the literature by investigating how consumers’ perceived value affects their anticipated emotional feelings of guilt and pride leading to the switch from meat-based to plant-based diets at restaurants.

The present research aimed to understand how to predict and promote plant-based meat (PBM) consumption.

In Study 1 (N = 550), the authors investigated the psychosocial antecedents of the intentions to add PBM and to replace animal meat with PBM. In Study 2 (N = 390), the authors tested the effectiveness of different environmental messages promoting PBM consumption. The authors compared the effects of an addition message condition (i.e. a message promoting the addition of PBM to one's diet), a replacement message condition (i.e. a message promoting the replacement of animal meat with PBM) and a control condition (i.e. no message). In both studies, the authors considered the moderation of past PBM consumption (PMB eaters vs PBM noneaters).

Study 1 showed that a positive attitude towards eating PBM and a high awareness of the environmental consequences of meat production were key antecedents of participants' intention to eat PBM. The role of the other psychosocial antecedents varied according to past PBM consumption. Study 2 showed that both addition and replacement messages increased non-PBM eaters' positive attitude towards eating PBM and in turn willingness to pay for PBM. Instead, only replacement messages increased PBM eaters' willingness to pay for PBM.

The present research developed a model integrating the key psychosocial predictors of people's intentions to eat PBM. Furthermore, it is the first research that compared the persuasiveness of different environment messages to promote PBM consumption.

The adverse effects on environmental sustainability, human health and animal welfare are often cited as the main reasons for reducing animal-based meat production and consumption. This study explored the food choice motives that determine consumer attitude toward plant-based meat (PBM) as a sustainable meat alternative. The theory of planned behavior (TPB) was applied to further determine whether an individual’s attitude toward PBM, subjective norms and perceived behavioral control influence their willingness to try novel meat substitutes (i.e. PBM). Finally, the moderating effect of meat attachment was also considered.

Online self-reported questionnaires were administered in Taiwan, and 294 valid questionnaires were collected. Structural equation modeling (SEM) and moderated regression were employed for analysis.

The results clarified the food choice motives that influenced consumer attitude toward PBM and revealed that attitude and subjective norms pertaining to trying PBM explained up to 35.03% of the variance in consumer willingness to try PBM. Notably, consumer meat attachment moderated the positive relationship between consumer attitude toward PBM and willingness to try PBM such that it became negative.

On the basis of the empirical findings regarding the food choice motives that influence consumer attitude and willingness to try PBM, this study provided practical implications for marketers seeking to increase consumer willingness to try PBM.

The main theoretical contribution of this research is that food choice motives should be considered in a TPB model to explain consumer willingness to try PBM. The moderating effect of consumer meat attachment should also be considered.

To gain a better and more comprehensive understanding, this study aims to investigate the literature to explore the two popular diets’ health benefits and concerns. Google Scholar and PubMed were used to search for available and relevant nutrition and health articles that pertain to the benefits and concerns of plantogenic and ketogenic diets. Search terms like low carbohydrate, diet, ketogenic, vegetarian and chronic diseases were used. Information was obtained from review articles and original research articles and checked for accuracy. Ketogenic diets have been used for a long time for convulsion in children and now reappeared for weight loss purposes.

Ketogenic and plantogenic (plant-based) diets have been adopted today by many professionals and the public.

Ketogenic diets have been used for a long time for convulsion in children and now reappeared for weight loss purposes. Plantogenic diets also have been practiced for many years for religious, health and environmental reasons. Compared to plantogenic diets, ketogenic diets lack long-term evidence of its potential benefits and harm.

Maybe Lacto-ovo vegetarian and pesco-vegetarian (eat fish but not meats) diets are OK. However, for strict plantogenic diets (total plantogenic/vegan diet), the risk of mineral or vitamin deficiency is present (Melina et al., 2016). Of particular concern is dietary vitamin B12, which is obtained mostly from animal sources (Melina et al., 2016). A long-term deficiency of vitamin B12 can lead to macrocytic anemia and cause neuro and psychological effects (Obeid et al., 2019). Also, omega-3 fatty acids may be deficient in such a diet and probably need to be supplemented on those who follow the total plantogenic diet (Melina et al., 2016). Other deficiencies of concern would be zinc, iron, calcium, vitamin D and iodine (Melina et al., 2016). Another disadvantage is that many junk foods could be easily classified within the plantogenic diet, such as sugar, cakes, French fries, white bread and rice, sugar-sweetened beverages and sweets in general. These items are related to higher weight gain and, consequently, to a higher incidence of diabetes and other chronic diseases (Schulze et al., 2004; Malik et al., 2006; Fung et al., 2009).

Plantogenic diets were concluded to have sustainable health benefits for humans and the environment over ketogenic diets, which could be used but under professional follow-up only.

The menopausal transition (MT) is a period when there may be an increase in visceral fat mass and a worsening of cardiometabolic risk factors. Few studies have evaluated the efficacy of plant-based low-calorie diets on groups of women at different stages of MT. The purpose of this study is to compare the effectiveness of a high plant-to-animal protein ratio diet in women of similar age but with different fertility statuses.

Subjects were divided into three groups according to their fertility status at the baseline: “premenopausal” (n = 11), “perimenopause” (n = 14) and “postmenopause” (n = 18). Body composition (BC) was measured at the beginning and after eight months of treatment. Individualised lifestyle treatment included a strong component of plant-based foods.

Forty-three overweight or obese Caucasian women (age 52.3 ± 4.5 years, body mass index 30.6 ± 5.4 kg/m2, fat mass 33.1 ± 9.3 kg data presented as means ± SD) were included in the study. Mean physical activity was 8.4 ± 7.6 metabolic equivalent of tasks/week. Subjects had an improvement in BC (fat mass −5.6 ± 4.0 kg, p < 0.001 protein −0.3 ± 0.5 kg, p < 0.001), HDL-C and systolic blood pressure values. Waist circumference and hip circumference decreased by 4.1 ± 3.1 cm and −6.0 ± 4.3 cm, respectively. Weight loss resulted in a significant improvement in some blood lipid values, such as total and high-density lipoprotein cholesterol. Adherence to a high plant protein diet helps adult women with different fertility statuses to improve BC and reduce cardiovascular risk factors. Long-term studies with larger sample sizes are needed to confirm these findings.

In pre-peri- and post-menopausal adult women, a diet high in plant proteins improves body composition and reduces cardiovascular risk factors.

Plant-based diets have been related to decreasing morbidity and mortality of many non-communicable diseases. The purpose of this study was to investigate the relationship between plant-based diets and lipid profiles and anthropometric indices.

This cross-sectional study was performed on 236 men and women selected from Shiraz health-care centers. This study used a 168-item food frequency questionnaire to calculate plant-based diet index (PDI), healthy plant-based diet index (hPDI) and unhealthy plant-based diet index (uPDI). Total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol and triglycerides were measured. Furthermore, body mass index, a body shape index and conicity index (CI) were calculated after measuring weight, height and waist circumference.

Higher score of PDI was significantly related to higher triglycerides level (OR = 2.16; 95% CI: 1.04, 4.48; P = 0.03). In the fully adjusted model, there was a significant association between ABSI and hPDI (OR = 4.88; 95% CI: 1.17, 20.24; P = 0.03). A significant inverse association was observed between uPDI and high-density lipoprotein (HDL) (OR = 0.45; 95% CI = 0.21, 0.98; P = 0.03). Also, this study found a decreasing, but insignificant trend in relation of ABSI (OR = 0.72; 95% CI = 0.22, 2.34) and CI (OR = 0.41; 95% CI = 0.06, 0.56) with PDI.

Further studies are needed to explore the association of PDI with anthropometric indices and lipid profile and also to assess the potential causality of the observed associations. Plant-based diets according to their contents could affect triglycerides, HDL and anthropometric properties.

Hence, dietitians should consider the findings of this study such as the inverse effect of unhealthy plant-based diets on HDL and the relation between healthy plant-based diets and WC and abdominal obesity.

This study showed that adherence to a plant-based diet was related to higher triglycerides levels. Also, uPDI was inversely associated with HDL level. Furthermore, participants who adhered more to a healthy plant-based diet had higher abdominal adiposity.

This study aims to identify effective ways to promote plant-based foods in quick-service restaurants by considering customers’ food-related health involvement.

This study conducted a 2 (message format: myth/fact or fact-only) × 2 (message focus: benefit- or attribute-focused) × 2 (health involvement: high or low) quasi-experimental design via a scenario-based online survey. A multivariate analysis of covariance and a bootstrapping approach were used to test the hypotheses (N = 365).

The results indicated that message format and focus jointly influenced customers’ perceived health consequences of plant-based foods and purchase intentions; customers’ health involvement altered the two-way interaction between message format and focus; and perceived health consequences mediated the effects of message format and focus as and customers’ health involvement on purchase intentions.

This study identifies the effectiveness of message format and focus in promoting plant-based foods and extends the sustainable product promotion literature by using resource matching theory and the elaboration likelihood model. Future studies should use field studies to examine how can message framing influence customers’ actual behaviors when purchasing plant-based foods.

This study can help quick-service restaurants better promote plant-based foods considering message format and focus and customers’ food-related health involvement.

This is one of only a few studies that have tested how messages containing both negative and positive information about a product could help promote plant-based foods.
