Convenient meat and meat products. Societal and technological issues

Bodybuilders and high-level meat consumers' behavior towards rabbit, beef, chicken, turkey, and lamb meat: A comparative review

In bodybuilders' diets, protein plays a crucial role in supporting muscle growth and repairing damaged muscle tissue. These individuals meet their protein needs by combining dietary sources with supplements. Animal-based proteins are often preferred over plant-based proteins because they are believed to better support muscle protein synthesis. This review explores the meat consumption patterns of bodybuilders and high-level meat consumers, focusing on rabbit, beef, chicken, turkey, and lamb. We describe and compare the types of meat bodybuilders commonly consume and provide an overview of protein supplements, including meat-based options, plant-based alternatives, and whey-based products. Our aim is to gain insight into the dietary preferences of bodybuilders and high-level meat consumers, considering their nutritional requirements and the potential effect on the meat industry. We conducted an extensive search across various databases, including Scopus, Web of Science, PubMed, and Google Scholar. We found that individual choices vary based on factors such as attitudes, trust, taste, texture, nutritional content, ethical considerations, and cultural influences. Nutritional factors, including protein content, amino acid profiles, and fat levels, significantly influence the preferences of bodybuilders and high-level meat consumers. However, it is crucial to maintain a balance by incorporating other essential nutrients such as carbohydrates, healthy fats, vitamins, and minerals to ensure a complete and balanced diet. The findings from this review can inform strategies and product development initiatives tailored to the needs of bodybuilders and discerning meat enthusiasts.

Quality and Processability of Modern Poultry Meat

The poultry meat industry has gone through many changes. It moved from growing dual-purpose birds (meat and egg production) taking ~110 days to reach 1.2 kg 100 years ago, to developing specialized meat breeds that grow to 2.5 kg within ~40 days. It also moved from selling ~80% whole birds to mostly selling cut up and further processed products in the Western world. This necessitated building large, centralized processing plants, capable of processing 15,000 birds per hr on a single line (60 years ago only 2500), that require higher bird uniformity (size, color, texture). Furthermore, consumer demand for convenient products resulted in introducing many cut-up fresh poultry (some companies have 500 SKU) and further processed products (chicken nuggets did not exist 50 years ago). Those developments were possible due to advancements in genetics, nutrition, medicine, and engineering at the farm and processing plant levels. Challenges keep on coming and today a rise in myopathies (e.g., so called woody breast, white striping, spaghetti meat), requires solutions from breeders, farmers, and processing plants, as more automation also requires more uniformity. This review focuses on the changes and challenges to the processing industry segment required to keep supplying high quality poultry to the individual consumer.

Rabbit meat: valuable nutrition or too-cute-to-eat?

Rabbit meat is a component of traditional diets, often incorporated into iconic dishes of regional cuisine. Its consumption can be traced back to the ancient civilisations of the Mediterranean and beyond, well into the Palaeolithic era. Even though it has been representing considerable nutritional and cultural value for millennia, a decline in consumption is now noticeable. Specific categorial dynamics are at play, related to the various superimposed roles of rabbits as livestock, game, pests, laboratory animals and pets. Their perceived cuteness in particular can lead to emotional responses that are hard to reconcile with the sensitivities of the post-domestic paradigm. Such effects compromise the acceptability of rabbit meat in contemporary Western societies that are typified by problematic human-animal interactions and a disconnect from the food chain. Young and urban populations in particular now seem to have difficulties facing the notion that food production requires the killing of animals. As a result, a traditional food source risks becoming irrelevant despite its high nutritional value and potential for sustainable meat production, due to reasons that are emotive rather than rational.

Lived experience of dietary change among Chinese colorectal cancer survivors in Hong Kong: A qualitative study

OBJECTIVES

This is a qualitative study which aims to understand the lived experience of dietary changes among Chinese survivors of colorectal cancer who participated in a dietary intervention.

SETTING

The surgical and oncological departments of four public hospitals in Hong Kong.

PARTICIPANTS

Fifty-five Chinese colorectal cancer survivors who were aged 18 years or above and had received potentially curative treatment in the surgical and oncological departments in Hong Kong were examined. Participants' mean age was 64 years, with 29 (53%) males.

INTERVENTION

A 12-month dietary intervention delivered via face-to-face motivational interviews, fortnightly motivational phone calls, monthly electronic pamphlets, quarterly newsletters and quarterly group meeting.

OUTCOME MEASURE

We adopted the qualitative approach to capture participants' perspectives and to apply the understanding pragmatically in everyday life. Content analysis was conducted.

RESULTS

We identified themes of motives to changes of dietary practices including (1) individual commitment to dietary change; (2) adaptive strategies in interpersonal contexts and (3) working with healthcare professionals during the journey.

CONCLUSIONS

The findings demonstrated how Chinese custom and culture posing unique challenges to colorectal cancer survivors and the need of having dietary advice from healthcare professionals. Participants were motivated to change their eating habits by support from family, friends and healthcare professionals. Our findings could help healthcare professionals provide specific dietary advice and guidance to Chinese colorectal cancer survivors.

A Review Study of a Green Diet and Healthy Ageing

Nowadays people are living longer, and there has been a substantial growth in the global elderly population in the past decades. While life expectancy is increasing, there are growing concerns towards the heavy financial and social burdens related to chronic diseases among the elderly. These have been critical health care issues, and healthy ageing is considered a top priority in public health. Diet and eating habits are crucial factors contributing to healthy ageing. These important aspects have attracted much attention in health research, particularly in consideration of the causes and management of chronic conditions which affect most elder adults in the world. Recently, a growing number of investigations have reported significant findings on the association of reduction in the risks of chronic non-communicable diseases with plant-based diets. Meanwhile, there have been worldwide initiatives and programmes implemented for reduction of salt intake. A green diet, which emphasises the consumption of a diet rich in plant foods with minimal portions of red or processed meat and reduced salt intake, is advocated with due consideration to the importance of sustainable environment and healthy ageing. This paper highlights a brief review of the recent advance of knowledge in diet and health, its effects on the elderly and the significance of a green diet on healthy ageing. Implications for a green diet and recommendations for future research are also discussed.

Application of natural antioxidant extract from guava leaves (Psidium guajava L.) in fresh pork sausage

The current study was conducted to determine the antioxidant efficacy of guava leaf extract (3000 to 6000 ppm on fat basis) in fresh pork sausage, compared with negative control (CON) and 200 ppm butylated hydroxytoluene (BHT), for 0, 1, 4, 7, 10, and 14 d at 4 °C. The extract provided a total antioxidant capacity of 1505 μmol trolox equivalence/g. From d 4, the extract at 5000 and 6000 ppm provided greater (P < .05) antioxidant capacity than the CON and was either similar (P > .05) or greater (P < .05) than BHT. From d 4, the sausage formulated with 4000 to 6000 ppm of guava leaf extract had less conjugated dienes, lower peroxide and acidic values, less thiobarbituric reactive substances value, and better color (P < .05) than the CON and did not differ from BHT (P > .05). Guava leaf extract at 4000 ppm or greater is effective in preventing oxidation in fresh pork sausage.

Looking at non-sensory factors underlying consumers' perception of smoked bacon

Smoked bacon is a food consumed everywhere and previous work has focused on the sensory properties and acceptability of the product. However, little attention has been given to the non-sensory factors that drive sensory and hedonic perception of this product. In this context, the aim of this work was to study the influence of non-sensory factors on consumer behavior towards smoked bacon, using projective mapping coupled with conjoint analysis. Eight visual stimuli were created using a full factorial design with three factors (convenience, healthiness, and context of consumption), at two levels each. Ninety-five consumers positioned the stimuli in a two-dimensional space considering their similarities and differences, and then, rated their expected liking and purchase intention. According to the projective mapping, consumers based the representation of the stimuli on the three factors under study, but conjoint analysis indicated that healthiness was the most important factor, followed by the context of consumption and convenience. The findings of this study may help in the selection of future strategies in the process of food development, in order to launch products with greater chance of success in the market.

Raw meat quality and salt levels affect the bacterial species diversity and community dynamics during the fermentation of pork mince

Acidification level and temperature modulate the beneficial consortia of lactic acid bacteria (LAB) and coagulase-negative staphylococci (CNS) during meat fermentation. Less is known about the impact of other factors, such as raw meat quality and salting. These could for instance affect the growth of the pathogen Staphylococcus aureus or of Enterobacterales species, potentially indicative of poor fermentation practice. Therefore, pork batters from either normal or borderline quality (dark-firm-dry, DFD) were compared at various salt concentrations (0-4%) in meat fermentation models. Microbial ecology of the samples was investigated with culture-dependent techniques and (GTG)₅-PCR fingerprinting of genomic DNA. Whilst Lactobacillus sakei governed the fermentation of normal meat, Lactobacillus curvatus was more prominent in the fermentation of the DFD meat variant. CNS were favoured during fermentation at rising salt concentrations without much effects on species diversity, consisting mostly of Staphylococcus equorum, Staphylococcus saprophyticus, and Staphylococcus xylosus. During fermentation of DFD meat, S. saprophyticus was less manifest than during that of normal meat. Enterobacterales mainly emerged in DFD meat during fermentation at low salt concentrations. The salt hurdle was insufficient to prevent Enterobacterales when acidification and initial pH were favourable for their growth.

Children's consumption of rabbit meat

<p>The nutritional and dietary properties of rabbit meat make it an ideal food for children, recommended by the World Health Organisation. However, the presence of children under 18 in the home has been found to decrease the frequency of rabbit meat consumption. If we focus on households with children under 18, 52.5% of minors do not consume rabbit meat. The main reason why children (intended as people under 18 yr old) do not consume rabbit meat is the fact that they do not like it (40.9%) and because it is not bought/eaten at home (30.9%). Faced with this situation, there is a pressing need to seek appropriate strategies to adapt rabbit meat for consumption by the youngest family members. In light of the results, the following strategies are proposed. First, the development of functional foods for babies and children, such as rabbit meat enriched with ω3 and docosahexaenoic acid. Secondly, improving meat tenderness. Third, adapting rabbit meat presentations for children (burgers, nuggets, sausages, marinades …), converting them into convenience products for parents and extending their shelf life. Fourth, adapting the labelling/packaging for children to attract attention of both parents and offspring. Finally, developing communication strategies on the nutritional value of rabbit meat aimed at both children and parents. It is observed that if minors consume rabbit meat, they also eat other types of meat such as lamb and beef more often. Therefore, in this type of households a varied and complete diet is consumed in terms of meat consumption, so it would be necessary to rethink joint communication strategies among the three meat sectors. Promoting rabbit meat consumption among the under 18s has several consequences, as in the future they will be in charge of household purchases or share this responsibility.</p>

Rethinking human-animal relations: The critical role of social psychology

People deeply value their social bonds with companion animals, yet routinely devalue other animals, considering them mere commodities to satisfy human interests and desires. Despite the inherently social and intergroup nature of these complexities, social psychology is long overdue in integrating human-animal relations in its theoretical frameworks. The present body of work brings together social psychological research advancing our understanding of: 1) the factors shaping our perceptions and thinking about animals as social groups, 2) the complexities involved in valuing (caring) and devaluing (exploiting) animals, and 3) the implications and importance of human-animal relations for human intergroup relations. In this article, we survey the diversity of research paradigms and theoretical frameworks developed within the intergroup relations literature that are relevant, perchance critical, to the study of human-animal relations. Furthermore, we highlight how understanding and rethinking human-animal relations will eventually lead to a more comprehensive understanding of many human intergroup phenomena.

Eating with our eyes (closed): Effects of visually associating animals with meat on antivegan/vegetarian attitudes and meat consumption willingness

Negative attitudes toward vegetarians/vegans (i.e., veg*ns) are common, particularly among those who desire/like/consume meat more. In two studies, we replicated and extended past work, showing that visual reminders of meat’s animal origins (vs. images of meat alone) decreased meat consumption willingness via increased empathy for animals, distress about meat consumption, and disgust for meat. We also assessed how animal–meat reminders influence antiveg*n attitudes. In Study 1 ( N = 299) experimental animal–meat reminders (vs. meat-alone images) indirectly reduced negative attitudes toward veg*ns via increased empathy and distress (together, but not independently). The same manipulation in Study 2 ( N = 280) lowered antiveg*n attitudes through greater empathy and lowered veg*n threat through greater distress. Implications for promoting less antiveg*n attitudes are discussed.

Meat as a Pharmakon: An Exploration of the Biosocial Complexities of Meat Consumption

In contemporary dietary advice, meat is depicted as a pharmakon: it is believed to either heal or poison the human body (and mind). Often, it also serves as a scapegoat for a wide range of public health issues and other societal problems. Related attitudes, practices, and beliefs pertain to a demarcated mode of thinking or episteme that is characteristic for the so-called post-domestic or industrialized societies. The latter are not only typified by an abundant yet largely concealed production of meat, but increasingly also by moral crisis and confusion about its nutritional meaning. For an improved appreciation of the ambiguous position of meat in human health and disease, as well as the concomitant scattering into different subject positions (e.g., the omnivore, flexitarian, vegetarian, vegan, permaculturalist, and carnivore position), an interdisciplinary approach is required. To this end, the current study tentatively combines food research with a selection of (post-structuralist) concepts from the humanities. The aim is to outline a historical and biosocial need for meat (as well as its rejection) and to analyze how its transformative effects have contributed to a polarized discourse on diet and well-being in academia and society at large. Excessive categorization (for instance with respect to meat's alleged naturalness, normalness, necessity, and niceness) and Manichean thinking in binary opposites are among the key factors that lead to impassioned yet often sterile debates between the advocates and adversaries of meat eating in a post-truth context.

Rabbit meat in need of a hat-trick: from tradition to innovation (and back)

Consumption of rabbit meat traces back to the ancient civilizations that prospered around the Mediterranean. Due to their small size, rabbits have mostly been included in traditional meals for direct consumption, with little historical urgency to develop preservation methods. Therefore, rabbit-based dishes are widespread throughout Europe, but few processed products are found. Despite its longstanding culinary value, an overall decline in the consumption of rabbit meat is discernible. As for all meat, this is related to a complex assemblage of contemporary anxieties about health, animal welfare, and the environment. Also, specific categorial dynamics are at play because rabbits have superimposed roles (e.g., livestock, game, vermin, and pets). For instance, their aspect of cuteness seems to interfere with their acceptability as a food. To counter the declining consumption of this valuable meat, reassuring discourses are required to point out its historical merit in health and culture ("story meat"). Also, its distinctive sensorial traits, nutritional profile, and technological properties should be valorized.

Consumers' willingness to pay for reprocessed fried chicken: A way of reducing uneaten food

Substantial food loss and waste occur worldwide; approximately one third of produced food is lost or wasted annually, which worsens problems such as starvation and environmental degradation. This study examines the possibility of selling reprocessed meat products made from raw meat near its sell-by date, using Japanese fried chicken as an example. If reprocessed products are accepted by consumers, this will significantly contribute to reducing food waste in grocery stores. Because reprocessing does not require a reduction in current meat consumption, selling reprocessed foods is a more feasible and realistic way to reduce food waste compared to other initiatives, such as "Meat Free Monday." We use a choice experiment to elicit consumer preference for reprocessed fried chicken. Our results show that the willingness to pay for reprocessed fried chicken is above 90% of that of regular chicken, which implies a high feasibility of selling such products.

Technological aspects of horse meat products - A review

Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pâté) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pâtés. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals.
