Abstract
The future of plant-based diets is a complex public health issue inextricably linked to planetary health. Shifting the world's population to consume nutrient-rich, plant-based diets is among the most impactful strategies to transition to sustainable food systems to feed 10 billion people by 2050. This review summarizes how international expert bodies define sustainable diets and food systems and describes types of sustainable dietary patterns. It also explores how the type and proportion of plant- versus animal-source foods and alternative proteins relate to sustainable diets to reduce diet-related morbidity and mortality. Thereafter, we synthesize evidence for current challenges and actions needed to achieve plant-based sustainable dietary patterns using a conceptual framework with principles to promote human health, ecological health, social equity, and economic prosperity. We recommend strategies for governments, businesses, and civil society to encourage marketplace choices that lead to plant-rich sustainable diets within healthy, equitable, and resilient agroecological food systems.

Surya Ulhas R, Ravindran R, Malaviya A, Priyadarshini A, Tiwari BK, Rajauria G. A review of alternative proteins for vegan diets: Sources, physico-chemical properties, nutritional equivalency, and consumer acceptance. Food Res Int 2023; 173:113479. [PMID: 37803803 DOI: 10.1016/j.foodres.2023.113479] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Revised: 07/30/2023] [Accepted: 09/13/2023] [Indexed: 10/08/2023]
Abstract
Alternate proteins are gaining popularity as a more sustainable and environmentally friendly alternative to animal-based proteins. These proteins are often considered healthier and are suitable for people following a vegetarian or vegan diet. Alternative proteins can be recovered from natural sources like legumes, grains, nuts, and seeds, while single cell proteins (mycoproteins), and algal proteins are being developed using cutting-edge technology to grow fungus, yeast and algal cells in a controlled environment, creating a more sustainable source of protein. Although, the demand for alternative protein products is increasing, there still happens to be a large gap in use among the general consumers mainly stemming from its lower bioavailability, lack of nutritional equivalency and reduced digestibility compared to animal proteins. The focus of the review is to emphasize on various sources and technologies for recovering alternative proteins for vegan diets. The review discusses physicochemical properties of alternative proteins and emphasise on the role of various processing technologies that can change the digestibility and bioavailability of these proteins. It further accentuates the nutritional equivalency and environmental sustainability of alternative protein against the conventional proteins from animals. The food laws surrounding alternative proteins as well as the commercial potential and consumer acceptance of alternative protein products are also highlighted. Finally, key challenges to improve the consumer acceptability and market value of plant-based proteins would be in achieving nutrient equivalency and enhance bioavailability and digestibility while maintaining the same physicochemical properties, taste, texture, as animal proteins, has also been highlighted.

Abstract
A meat analogue is a casserole in which the primary ingredient is something other than meat. It goes by various other names, such as meat substitute, fake meat, alternative meat, and imitation meat. Consumers growing interest in improving their diets and the future of the planet have contributed to the move towards meat substitutes. This change is due to the growing popularity of low-fat and low-calorie diets, the rise of flexitarians, the spread of animal diseases, the loss of natural resources, and the need to cut down on carbon emissions, which lead to greenhouse effects. Plant-based meat, cultured meat, algal protein-based meat, and insect-based meat substitutes are available on the market with qualities like appearance and flavor similar to those of traditional meat. Novel ingredients like mycoprotein and soybean leg haemoglobin are mixed in with the more traditional soy proteins, cereals, green peas, etc. Plant-based meat is currently more popular in the West, but the growing interest in this product in Asian markets indicates the industry in this region will expand rapidly in the near future. Future growth in the food sector can be anticipated from technologies like lab-grown meat and its equivalents that do not require livestock breeding. Insect-based products also hold great potential as a new source of protein for human consumption. However, product safety and quality should be considered along with other factors such as marketability and affordability.

Abstract
The production of food, especially meat, has a high environmental impact. Many believe that the introduction of alternative proteins could substantially reduce animal meat consumption, resulting in a more sustainable food system. In this review, we critically evaluate the challenges and barriers that need to be overcome to ensure that these alternative proteins have the desired effects. We focus on conventional plant-based proteins (e.g., pulses, soy, and legumes), highly processed meat analogs (e.g., Quorn and the Impossible Burger), cultured meat, and insects. For a majority of consumers, meat seems to be too attractive to be substituted by plant proteins, cultured meat, or insects. There are certainly niche markets for these products, but worldwide meat consumption is still likely to grow in the future. We argue that technological solutions alone are not sufficient to substantially reduce meat consumption and that additional measures are needed.

Front Nutr 2022; 9:1087194. [PMID: 36618675 PMCID: PMC9815776 DOI: 10.3389/fnut.2022.1087194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 12/06/2022] [Indexed: 12/24/2022] Open
Abstract
Introduction Marketing plays an important role in consumers' perceptions and acceptance of new foods. The purpose of this study was to investigate the marketing strategies used for alternative protein products available in Australia in 2014, 2017, and 2021. Methods Product data were extracted from FoodTrack™, an established database of packaged supermarket products. Marketing strategies investigated included product format descriptors, front of pack (FOP) labeling claims, price, and in-store placement (2021 only). Results Data from 292 alternative protein products (n = 12 tofu-based products; n = 100 legume-based products; and n = 180 plant-based meats) were analyzed. Across the product range, "burgers" (n = 86), "strips and similar" (n = 51) and "sausages" (n = 42) were the most common product formats, accounting for ∼61% of the product range. Nutrient content claims featured on 273 (93%) products. "Positive" nutrient claims (those highlighting the presence of a nutrient) occurred on FOP labels four times more than "negative" nutrient claims (those highlighting the absence or low levels of a nutrient; 432 versus 101, respectively). Protein-related claims were the most common "positive" nutrient claim (n = 180, 62%). Health claims on FOP labels appeared on 10% of products. Most products (n = 265, 91%) mentioned a dietary pattern (such as "vegetarian" and "plant-based"), or a combination of dietary patterns on their FOP label. The price of alternative products increased over time; between 2014 and 2021, on average, the unit price increased (9% increase, p = 0.035) and the pack size decreased (14% decrease, p < 0.001). There was inconsistency in product placement across the eight stores visited. Occasionally (n = 3 of 13 locations), chilled alternative protein products were positioned near conventional meat products. More commonly, alternative protein products shared space with other vegetarian products (such as non-dairy cheeses and tofu blocks) or alongside convenience products, suggesting these products are promoted as convenience foods, or options for individuals with special dietary needs. Discussion This study provides a useful evidence base to understand the marketing strategies used for alternative protein products. It appears from this analysis that considerable effort has gone into providing consumers with a level of familiarity and comfort prior to purchasing these alternative protein products.
