Impossible to go Beyond Beef? A Nutriomics Comparison

Abstract Concerns regarding the effects of red meat on human and environmental health are prompting consumer interest in plant-based diets. As global food systems strive to meet the dietary needs of an estimated mid-century population of 10 billion, a new generation of plant-based meat alternatives—formulated to mimic the taste and nutritional composition of red meat—have attracted considerable consumer interest, research attention, and media coverage. We used untargeted metabolomics to provide an in-depth comparison of the nutrient profiles of grass-fed ground beef and a market-leading plant-based meat alternative. Metabolomics revealed a 90% difference in nutritional profiles beef and a popular plant-based meat, many of which can have important consumer health implications. This information could not be determined from their Nutrition Facts, which suggests nutritional similarity. Our findings indicate that beef and a popular plant-based meat should not be viewed as nutritionally interchangeable, but as complementary in terms of provided nutritional entities. As society aims to increase food production with ~ 60% by 2050, the meat and the plant-based meat industries will likely coexist and have to complement each other in order this reach this goal.

AbstractA new generation of plant-based meat alternatives—formulated to mimic the taste and nutritional composition of red meat—have attracted considerable consumer interest, research attention, and media coverage. This has raised questions of whether plant-based meat alternatives represent proper nutritional replacements to animal meat. The goal of our study was to use untargeted metabolomics to provide an in-depth comparison of the metabolite profiles a popular plant-based meat alternative (n = 18) and grass-fed ground beef (n = 18) matched for serving size (113 g) and fat content (14 g). Despite apparent similarities based on Nutrition Facts panels, our metabolomics analysis found that metabolite abundances between the plant-based meat alternative and grass-fed ground beef differed by 90% (171 out of 190 profiled metabolites; false discovery rate adjusted p < 0.05). Several metabolites were found either exclusively (22 metabolites) or in greater quantities in beef (51 metabolites) (all, p < 0.05). Nutrients such as docosahexaenoic acid (ω-3), niacinamide (vitamin B3), glucosamine, hydroxyproline and the anti-oxidants allantoin, anserine, cysteamine, spermine, and squalene were amongst those only found in beef. Several other metabolites were found exclusively (31 metabolites) or in greater quantities (67 metabolites) in the plant-based meat alternative (all, p < 0.05). Ascorbate (vitamin C), phytosterols, and several phenolic anti-oxidants such as loganin, sulfurol, syringic acid, tyrosol, and vanillic acid were amongst those only found in the plant-based meat alternative. Large differences in metabolites within various nutrient classes (e.g., amino acids, dipeptides, vitamins, phenols, tocopherols, and fatty acids) with physiological, anti-inflammatory, and/or immunomodulatory roles indicate that these products should not be viewed as truly nutritionally interchangeable, but could be viewed as complementary in terms of provided nutrients. The new information we provide is important for making informed decisions by consumers and health professionals. It cannot be determined from our data if either source is healthier to consume.

Experimental Use

Purpose The purpose of this paper is to discuss and evaluate the role of hybrid forums as tools to address specific controversies related to sustainable practices in localized agro-food systems (LAFS). Design/methodology/approach In contrast with other conventional public engagement methods, such as citizen juries, consensus conferences, focus groups or deliberative processes, hybrid forums entail a more dynamic and democratic mechanism to reflect and act together, with the aim of constructing a common project around a defined challenge (Callon et al., 2001, 2009). They can offer an enriching and challenging methodological approach in the context of LAFS, especially in the discussion of controversial issues around food chain sustainability. The authors present here a new generation of hybrid forums: HF 2.0. Findings HF 2.0. represent both a methodological tool and a real experience of dialogic democracy, two interactive aspects which are closely interlinked and rest upon each other. The authors argue that the attractiveness of HF 2.0. is notable in at least two ways: first, they provide a solid democratic and reflective mechanism to stimulate effective dialogue and knowledge-exchange among different stakeholders; second, they contribute as an important methodological evidence-based tool, which can be used as a launching pad for shaping local action groups and community partnerships’ strategies aimed at fostering local development. Originality/value This paper attempts to provide a methodological discussion over the experimental use of HF 2.0. in the context of LAFS and assesses their effectiveness in the co-construction of knowledge. The authors explore their pragmatic validity in addressing controversies over local and sustainable seafood via empirical applications in Norway and the UK.

Media coverage of suicide has been repeatedly shown to influence suicide rates. The Werther Effect (WE) qualifies the propensity of suicide stories to prompt imitative behaviors. By contrast, the Papageno effect (PE) was more recently identified as a way for journalists to contribute to suicide prevention through their productions. Crucially, both WE and PE depend on the quantitative (audience, redundancies, size of articles, etc.) and qualitative (type of story, editorial style, content, etc.) properties of the coverage.In order to promote the PE and limit the WE, the World Health Organization (WHO) have edited a guideline for media professionals. For instance, journalists are advised to prohibit sensationalism, avoid pictures or details about the suicide method, and show due respect to the bereaved relatives. However, it is now clear that the only chance for these recommendations to be applied is to integrate their diffusion into a more general effort toward collaboration with journalists.Papageno is a French national suicide prevention program that fully relies on learners to rise awareness about suicide and its coverage. It mainly consists in pair-meetings between psychiatry trainees and journalism students. Such an innovative formula breaks with the old top-down knowledge transmission model in order to foster personalized and sustainable sensitization. It aims at growing up a new generation of journalists who would be more aware of their responsibility concerning suicide and would more spontaneously resort to the WHO guidelines. Ultimately, the Papageno program strives for the creation of a new culture where journalists and psychiatrist would collaborate for a safer media coverage of suicide.Disclosure of interestThe author has not supplied his declaration of competing interest.

Over Time

Red meat often evokes a wide array of complex and contradictory arguments. It is viewed as the most expensive component of any diet, supplying many essential nutrients as part of a healthy, prudent eating plan. Yet, red meat is non-homogenous, unique to each country, and continually changing in composition. It is observed that the amount of fat on carcasses has reduced over time, simultaneously improving nutrient density through feed efficiency. The objective of this paper is to present composition data on South African lamb, mutton and beef, and report on the changes observed between local data and international data (for lamb and mutton), as well as changes in the composition of South African beef over time. South African lamb and mutton contain notably less fat and more nutrients per 100 g product than international sheep meat produced, rendering a lean product with a higher nutrient density. Compared to previous studies on South African beef, the current data indicate notable changes in the composition over time, specifically related to a reduction in fat content. This reduction together with changes in carcass weight has resulted in changes in carcass composition and thus changes in nutrient density. The data attest that in order to align industry processes, as well as legislation and marketing strategies, continued research on composition needs to be performed for the baseline information to remain relevant and accurate.Keywords: Beef, lamb, mutton, nutrient content, nutritional composition, South Africa

With the growing fleet of a new generation electric vehicles (EVs), it is essential to develop an adequate high power charging infrastructure that can mimic conventional gasoline fuel stations. Therefore, much research attention must be focused on the development of off-board DC fast chargers which can quickly replenish the charge in an EV battery. However, use of the service transformer in the existing fast charging architecture adds to the system cost, size and complicates the installation process while directly connected to medium-voltage (MV) line. With continual improvements in power electronics and magnetics, solid state transformer (SST) technology can be adopted to enhance power density and efficiency of the system. This paper aims to review the current state of the art architectures and challenges of fast charging infrastructure using SST technology while directly connected to the MV line. Finally, this paper discusses technical considerations, challenges and introduces future research possibilities.

AbstractObjectiveTo show that nutrition science is anchored in food systems and is influenced by the social, through the environmental to the cosmological, life's connections and rhythms. To indicate that an integrative approach is now becoming possible with advances in food technology, in the understanding of food choice and of human behaviour, and in a preparedness to recognise nutritional inputs in the full sweep of life-long well-being and health outcomes.MethodAn analysis of the much broader understanding of nutritionally related diseases from an ecological perspective, with attention to economic development, beginning with poverty alleviation. Recognition that the biological dimension of nutrition science is undergoing a profound reappraisal; that technologies will allow us to change the course of nutritionally related diseases for the better; and that nutrition science will find partners in information technology and telecommunications, food technology and energy technology.ConclusionA new generation of nutrition scientists can help build a new economy that supports development amongst communities, whether close or distant from each other. The opportunities for this kind of development to be realised between Asia, Latin America and Africa are considerable. At all times, however, nutrition scientists must uphold the paramount importance of good governance, conflict resolution and maternal literacy if their work is to achieve its growing potential.

The efficient use of natural resources is essential for the planet’s sustainability and ensuring food security. Colombia’s large availability of water resources in combination with its climatic characteristics allows for the development of many microalgae species. The use of microalgae can potentially contribute to sustainable production in support of the agri-food sector. The nutritional composition (proteins, carbohydrates, fatty acids, vitamins, pigments, and antioxidants) of microalgae along with the ease of producing high biomass yields make them an excellent choice for human and animal nutrition and agriculture. Several species of microalgae have been studied seeking to develop food supplements for pigs, ruminants, poultry, fish, crustaceans, rabbits, and even bees. Important benefits to animal health, production, and improved bromatological and organoleptic characteristics of milk, meat, and eggs have been observed. Based on the functional properties of some microalgae species, foods and supplements have also been developed for human nutrition. Moreover, because microalgae contain essential nutrients, they can be utilized as biofertilizers by replacing chemical fertilizers, which are detrimental to the environment. In view of the above, the study of microalgae is a promising research area for the development of biotechnology and bioeconomy in Colombia.
