Abstract
Cultured Meat (CM) is a growing field in cellular agriculture, driven by the environmental impact of conventional meat production, which contributes to climate change and occupies ≈70% of arable land. As demand for meat alternatives rises, research in this area expands. CM production relies on tissue engineering techniques, where a limited number of animal cells are cultured in vitro and processed to create meat-like tissue comprising muscle and adipose components. Currently, CM is primarily produced on a small scale in pilot facilities. Producing a large cell mass based on suitable cell sources and bioreactors remains challenging. Advanced manufacturing methods and innovative materials are required to subsequently process this cell mass into CM products on a large scale. Consequently, CM is closely linked with biofabrication, a suite of technologies for precisely arranging cellular aggregates and cell-material composites to construct specific structures, often using robotics. This review provides insights into contemporary biomedical biofabrication technologies, focusing on significant advancements in muscle and adipose tissue biofabrication for CM production. Novel materials for biofabricating CM are also discussed, emphasizing their edibility and incorporation of healthful components. Finally, initial studies on biofabricated CM are examined, addressing current limitations and future challenges for large-scale production.

Pires C. Superfoods for Type 2 Diabetes: A Narrative Review and Proposal for New International Recommendations. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1184. [PMID: 37511996 PMCID: PMC10384771 DOI: 10.3390/medicina59071184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 05/31/2023] [Accepted: 06/19/2023] [Indexed: 07/30/2023]
Abstract
Background and Objectives: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease affecting an estimated 537 million individuals worldwide. 'Superfoods' can be integrated into the diet of T2DM patients due to their health benefits. Study Objectives: (i) To carry out a narrative review of 'superfoods' with the potential to reduce glycaemic levels in T2DM patients (2019 to 2022), (ii) to identify 'superfoods' with the potential to reduce HbA1c and (iii) to propose new guidance on the use of 'superfoods'. Materials and Methods: A narrative review was carried out using the databases PubMed, SciELO, DOAJ and Google Scholar. The keywords were ["type 2 diabetes" and ("food" or "diet" or "nutrition") and ("glycaemia" or "glycemia")]. Only review studies were included. Results: Thirty reviews were selected. The 'superfoods' identified as having a potential impact on glycaemic control were foods with polyphenols (e.g., berries), fermented dairy products, whole cereals/grains, nuts and proteins, among others. The possibility of an extensive reduction in Hb1Ac was reported for fermented dairy products, especially yoghurts enriched with vitamin D or probiotics (HbA1c reduction of around 1%) or by increasing the fibre intake by 15 g (or up to 35 g) (HbA1c reduction of around 2%). Conclusion: It is recommended that the identified 'superfoods' are included in the diet of T2DM patients, although this should not substitute an appropriate diet and exercise plan. In particular, yoghurts and an increased fibre intake (by 15 g or up to 35 g) can be used as nutraceuticals. New recommendations on the introduction of 'superfoods' in the diet of T2DM patients have been proposed.

Abstract
Upon wetting, chia (Salvia hispanica L.) nutlets produce a gel-like capsule of polysaccharides called mucilage that comprises a significant part of their dietary fibre content. Seed/nutlet mucilage is often used as a texture modifying hydrocolloid and bulking dietary fibre due to its water-binding ability, though the utility of mucilage from different sources is highly structure-function dependent. The composition and structure of chia nutlet mucilage is poorly defined, and a better understanding will aid in exploiting its dietary fibre functionality, particularly if, and how, it is utilised by gut microbiota. In this study, microscopy, chromatography, mass spectrometry and glycome profiling techniques showed that chia nutlet mucilage is highly complex, layered, and contains several polymer types. The mucilage comprises a novel xyloamylose containing both β-linked-xylose and α-linked-glucose, a near-linear xylan that may be sparsely substituted, a modified cellulose domain, and abundant alcohol-soluble oligosaccharides. To assess the dietary fibre functionality of chia nutlet mucilage, an in vitro cumulative gas production technique was used to determine the fermentability of different chia nutlet preparations. The complex nature of chia nutlet mucilage led to poor fermentation where the oligosaccharides appeared to be the only fermentable substrate present in the mucilage. Of note, ground chia nutlets were better fermented than intact whole nutlets, as judged by short chain fatty acid production. Therefore, it is suggested that the benefits of eating chia as a "superfood", could be notably enhanced if the nutlets are ground rather than being consumed whole, improving the bioaccessibility of key nutrients including dietary fibre.

Fatty Acid Composition of Pseudocereals and Seeds Used as Functional Food Ingredients. LIFE (BASEL, SWITZERLAND) 2023; 13:life13010217. [PMID: 36676166 PMCID: PMC9863612 DOI: 10.3390/life13010217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 12/30/2022] [Accepted: 01/09/2023] [Indexed: 01/13/2023]
Abstract
In recent times, the popularity of seeds, other than cereals, in the diet has systematically grown. The fat contained in these products significantly affects their energy value as well as their biological and physicochemical properties, including their susceptibility to oxidation. The objective of this study is to evaluate the fat concentration and fatty acid (FA) composition of popular non-spice seeds used in food as a substitute for cereals or a functional additive. The research material consisted of thirteen groups of seeds derived from the following plants: amaranth, blue poppy, buckwheat, chia, flax, hemp, canihua, milk thistle, pumpkin, plantago, quinoa, sesame, and sunflower. The fat contents and fatty acid profiles differed significantly between the tested products and were dependent on the plant species. In all products, polyunsaturated fatty acids (PUFAs, 40-80% of total FAs) dominated. Linoleic acid was the main FAs in most tested seeds. The exceptions were chia and flax seeds, which were characterized by very high contents of α-linolenic acid, respectively, 62.0 and 51.4% of the total FAs. The share of monounsaturated FAs (mainly oleic acid) in the total FAs content was between 6 and 40%. All tested seeds (especially flax, chia, and hemp) have favorable values for their indexes of atherogenicity and thrombogenicity as well as the hypocholesterolemic/hypercholesterolemic ratio.

Abstract
Plant secondary metabolites are vital for human health leading to the gain the access to natural products. The quality of crops is the result of the interaction of different biotic and abiotic factors. Abiotic stresses during plant growth may reduce the crop performance and quality of the produce. However, abiotic stresses can result in numerous physiological, biochemical, and molecular responses in plants, aiming to deal with these conditions. Abiotic stresses are also elicitors of the biosynthesis of plant secondary metabolites in plants which possess plant defense mechanisms as well as human health benefits such as anti-inflammatory, antioxidative properties etc. Plants either synthesize new compounds or alter the concentration of bioactive compounds. Due to increasing attention towards the production of bioactive compounds, the understanding of crop responses to abiotic stresses in relation to the biosynthesis of bioactive compounds is critical. Plants alter their metabolism at the genetic level in response to different abiotic stresses resulting the changes in secondary metabolite production. Transcriptional factors regulate genes responsible for secondary metabolite biosynthesis in several plants under stress conditions. Understanding the signaling pathways involved in the secondary metabolite biosynthesis has become easy with the use of molecular biology. Therefore, aim of writing the review is to focus on secondary metabolite production in vegetable crops, their health benefits and transcription regulation under various abiotic stresses.

Abstract
The Blue Zones (BZs) are areas of the globe inhabited by exceptionally long-lived populations. They include the island of Okinawa in Japan, the island of Ikaria in Greece, the mountain area of the island of Sardinia in Italy, and the peninsula of Nicoya in Costa Rica. Their longevity is a relatively recent phenomenon that has been progressively investigated since the dawn of this century. Research efforts over the past two decades have sought to shed light on the factors associated with this longevity, as well as explore the possibility of lessons transferable to the general population. Among the features of BZ inhabitants, described in the literature, their eating habits hold a prominent place, as these have the advantage of being easily quantifiable and applicable on a larger scale. However, it is too often taken for granted that the mere fact of being documented in a long-lived population makes the diet a causal factor of that population's longevity; this is a claim which should be proven. Furthermore, it is implicitly assumed that a specific BZ diet is homogeneous and remains stable over time, whereas some evidence suggests the opposite. Therefore, this review summarizes our current knowledge of the BZ diets and discusses whether they can be considered as a paradigmatic example of healthy nutrition valid for anyone or, rather, a set of evolving food patterns that has offered benefits to a few specific communities in recent decades.
