“…A strategy that has been highlighted to help reduce the consumption of unsustainable meat is the development of innovative plant-based food products and other alternatives to animal-based proteins [ 9 ]. The most common alternatives to animal-based proteins currently available on supermarket shelves are beans and lentils (e.g., soya), grains and wheat-based proteins (e.g., seitan), and single-cell proteins (e.g., mycoprotein) [ 10 , 11 , 12 ]. Despite rapid expansions within this market on a global scale [ 11 , 13 ], acceptance of alternatives to animal-based proteins is often low among consumers, particularly when compared to meat and dairy products [ 12 ].…”

Indeed, it is notable that many consumers remain sceptical about the consumption of alternatives to animal-based proteins.…”

Overconsumption of meat has been recognised as a key contributing factor to the climate emergency. Algae (including macroalgae and microalgae) are a nutritious and sustainable food source that may be utilised as an alternative to animal-based proteins. However, little is known about the consumer awareness and acceptance of algae as a protein alternative. The aim of this qualitative study was to develop a rich and contextualised understanding of consumer beliefs about the use of algae in novel and innovative food products. A total of 34 participants from the UK assisted with our study. Each participant engaged in one focus group, with six focus groups conducted in total. Existing consumer knowledge of algae was discussed before participants explored the idea of algae-based food products. Reflexive (inductive) thematic analysis was used to analyse these data. Results showed that consumers have limited pre-existing knowledge of algae as a food source; however, participants were open to the idea of trying to consume algae. This anticipated acceptance of algae was influenced by several product attributes, including perceived novelty, edibility, healthiness, sustainability, and affordability. These findings highlight algae as a promising protein alternative to support plant-forward diets in the UK and identify key attributes to consider in future product development and marketing strategies.

“…We undertook an analysis of SAM and SAH in adult healthy subjects transitioning from an omnivore to either a vegan or a meat-rich diet. An increasing number of individuals are transitioning toward plant-based dietary patterns worldwide [ 27 , 28 , 29 , 30 , 31 ]. Regardless of personal motivations, which may include mitigation of climate change and food insecurity, animal welfare, and health improvement, the study of metabolism and disease prevention in such dieters has gained growing interest, especially in pediatric and adolescent populations [ 32 , 33 , 34 , 35 ].…”

“…As part of the methionine cycle, SAM synthesis and metabolism are dependent on the consumption of essential nutrients, such as methionine, folic acid, and cobalamin, whose intakes vary between diets. A growing number of people are transitioning toward plant-based diets worldwide [ 27 , 28 , 29 , 30 , 31 ]. Whether their motivations include mitigation of climate change and food insecurity, animal welfare, health improvement, or other, the study of how nutrition impacts metabolism in such dieters has gained renewed interest, both in adult and paediatric populations [ 32 , 33 , 34 , 35 ].…”

Analysis of S-Adenosylmethionine and S-Adenosylhomocysteine: Method Optimisation and Profiling in Healthy Adults upon Short-Term Dietary Intervention

et al. 2022

S-adenosylmethionine (SAM) is essential for methyl transfer reactions. All SAM is produced de novo via the methionine cycle. The demethylation of SAM produces S-adenosylhomocysteine (SAH), an inhibitor of methyltransferases and the precursor of homocysteine (Hcy). The measurement of SAM and SAH in plasma has value in the diagnosis of inborn errors of metabolism (IEM) and in research to assess methyl group homeostasis. The determination of SAM and SAH is complicated by the instability of SAM under neutral and alkaline conditions and the naturally low concentration of both SAM and SAH in plasma (nM range). Herein, we describe an optimised LC-MS/MS method for the determination of SAM and SAH in plasma, urine, and cells. The method is based on isotopic dilution and employs 20 µL of plasma or urine, or 500,000 cells, and has an instrumental running time of 5 min. The reference ranges for plasma SAM and SAH in a cohort of 33 healthy individuals (age: 19–60 years old; mean ± 2 SD) were 120 ± 36 nM and 21.5 ± 6.5 nM, respectively, in accordance with independent studies and diagnostic determinations. The method detected abnormal concentrations of SAM and SAH in patients with inborn errors of methyl group metabolism. Plasma and urinary SAM and SAH concentrations were determined for the first time in a randomised controlled trial of 53 healthy adult omnivores (age: 18–60 years old), before and after a 4 week intervention with a vegan or meat-rich diet, and revealed preserved variations of both metabolites and the SAM/SAH index.

“…Por ello Alae-Carew, Green, Et al. (2021) afirman que ahora en día los consumidores responsables demandan más compromiso ético, donde prime la trasparencia en las acciones tanto de la empresa que lo produce y de la persona que las consume, para lograr generar el equilibrio de sostenibilidad, donde no se vulnere al planeta ni a los derechos del trabajador.…”

La investigación tuvo como objetivo determinar el nivel de hábitos sobre consumo responsable en estudiantes de una universidad en la Región de Lambayeque. Para ello, se utilizó un diseño no experimental, empleando la encuesta como técnica y el instrumento cuestionario de preguntas. La metodología se basó en encuestar en forma aleatoria simple no estratificada de acuerdo con el interés de los investigadores en una sola oportunidad a 220 estudiantes que pertenecen al primer ciclo académico 2021-II de la universidad Señor de Sipán. Llegando a obtener resultados donde se evidencian el bajo nivel del consumo responsable por parte de los estudiantes universitarios participantes, donde se puede concluir el rol que juega la universidad para mejorar el nivel de hábitos de consumo en los estudiantes universitarios, donde sirvan de ejemplo a las demás personas de su entorno sobre buenos hábitos de consumo responsable.
