Multiple benefits of herbs: Polygonaceae species in veterinary pharmacology and livestock nutrition

Herbs rich in secondary metabolites may possess beneficial properties in livestock nutrition and health. 49 Polygonaceae species of European mountain regions were included in a qualitative systematic review based on the methodological framework of the PRISMA statement. 174 relevant publications were identified. They comprised 231 in vitro and 163 in vivo experiments with cattle, sheep, goats, poultry, pigs, and rodents. For 16 Polygonaceae species no reports were found. Fagopyrum esculentum and Fagopyrum tataricum showed potential as anti-inflammatory, antioxidative and metabolic modifying herbs and feeds improving intake and nitrogen conversion in broiler as well as milk quality and ruminal biotransformation in dairy cows. Polygonum aviculare was promising as an antimicrobial and anti-inflammatory drug or feed, improving performance and affecting ruminal biotransformation in sheep, and Polygonum bistorta as an anti-inflammatory drug or feed, improving performance in broiler and mitigating methane emissions in ruminants. Rumex obtusifolius showed potential as an antibacterial drug or feed improving ruminal biotransformation and preventing bloating in cows, while Rumex acetosa and Rumex acetosella had antimicrobial and anti-inflammatory properties. Furthermore, Polygonum minus, Polygonum persicaria, Rumex crispus and Rumex patientia possess interesting anti-inflammatory and antimicrobial activities. In conclusion, some Polygonaceae species show relevant properties that might be useful to prevent and treat livestock diseases, combined with nutritional benefits in performance, product quality, lowering ruminal methane and ammonia formation and transferring omega-3 fatty-acids from feed to tissue. The potential of such multifunctional plants for a holistic integration of veterinary, nutritional and ecological perspectives under a one-health approach of livestock management is discussed.

Ingredients, structure and reconstitution properties of instant powder foods and the potential for healthy product development: a comprehensive review

Instant foods are widely presented in powder forms across different food segments, which potentially can be formulated with functional or beneficial compounds to provide health benefits. Many reconstituted instant powder foods form colloidal suspensions with complex structures. However, designing instant powder food could be challenging due to the structural complexity and high flexibility in formulation. This review proposed a new classification method for instant powder foods according to the solubility of ingredients and the structure of the reconstituted products. Instant powder foods containing insoluble ingredients are discussed. It summarised challenges and current advances in powder treatments, reconstitution improvement, and influences on food texture and structure to facilitate product design in related industries. The characteristics and incorporation of the main ingredients and ingredients with health benefits in product development were reviewed. Different products vary significantly in the ratios of macronutrients. The macronutrients have limited solubility in water. After being reconstituted by water, the insoluble components are dispersed and swell to form colloidal dispersions with complex structures and textures. Soluble components, which dissolve in the continuous phase, may facilitate the dispersing process or influence the solution environment. The structure of reconstituted products and destabilising factors are discussed. Both particle and molecular structuring strategies have been developed to improve wettability and prevent the formation of lumps and, therefore, to improve reconstitution properties. Various types of instant food have been developed based on healthy or functional ingredients and exhibit positive effects on the prevention of non-communicable diseases and overall health. Less processed materials and by-products are often chosen to enhance the contents of dietary fibre and phenolic compounds. The enrichment of phenolic compounds, dietary fibres and/or probiotics tend to be simultaneous in plant-based products. The process of the ingredients and the formulation of products must be tailored to design the desired structure and to improve the reconstitution property.

Buckwheat and Cardiometabolic Health: A Systematic Review and Meta-Analysis

Buckwheat (BW) is suggested to have beneficial effects, but evidence on how it affects cardiometabolic health (CMH) is not yet established. We aimed to assess the effects of BW and/or its related bioactive compounds on cardiovascular disease (CVD) risk markers in adults. Five databases were searched for eligible studies. Observational prospective studies, nonrandomized or randomized trials were considered if they assessed BW, rutin or quercetin-3-glucoside intake and CVD risk markers. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting. We selected 16 human studies based on 831 subjects with mild metabolic disturbances, such as hypercholesterolemia, diabetes and/or overweight. Eight studies, investigating primarily grain components, were included in the meta-analyses (n = 464). High study heterogeneity was present across most of our analyses. Weighted mean difference (WMD) for subjects receiving BW supplementation, compared to controls, were - 0.14 mmol/L (95% CI: -0.30; 0.02) for total cholesterol (TC), -0.03 mmol/L (95% CI: -0.22; 0.16) for LDL cholesterol, -0.14 kg (95% CI: -1.50; 1.22) for body weight, -0.04 mmol/L (95% CI: - 0.09;0.02) for HDL cholesterol, -0.02 mmol/L (95% CI: -0.15; 0.11) for triglycerides and -0.18 mmol/L (95% CI: -0.36; 0.003) for glucose. Most of the studies (66.7%) had concerns of risk of bias. Studies investigating other CVD markers were scarce and with inconsistent findings, where available. Evidence on how BW affects CMH is limited. However, the available literature indicates that BW supplementation in mild dyslipidaemia and type 2 diabetes may provide some benefit in lowering TC and glucose, albeit non-significant. Our work highlights the need for more rigorous trials, with better methodological rigor to clarify remaining uncertainties on potential effects of BW on CMH and its utility in clinical nutrition practice.

How Healthy Are Non-Traditional Dietary Proteins? The Effect of Diverse Protein Foods on Biomarkers of Human Health

Future food security for healthy populations requires the development of safe, sustainably-produced protein foods to complement traditional dietary protein sources. To meet this need, a broad range of non-traditional protein foods are under active investigation. The aim of this review was to evaluate their potential effects on human health and to identify knowledge gaps, potential risks, and research opportunities. Non-traditional protein sources included are algae, cereals/grains, fresh fruit and vegetables, insects, mycoprotein, nuts, oil seeds, and legumes. Human, animal, and in vitro data suggest that non-traditional protein foods have compelling beneficial effects on human health, complementing traditional proteins (meat/poultry, soy, eggs, dairy). Improvements in cardiovascular health, lipid metabolism, muscle synthesis, and glycaemic control were the most frequently reported improvements in health-related endpoints. The mechanisms of benefit may arise from their diverse range of minerals, macro- and micronutrients, dietary fibre, and bioactive factors. Many were also reported to have anti-inflammatory, antihypertensive, and antioxidant activity. Across all protein sources examined, there is a strong need for quality human data from randomized controlled intervention studies. Opportunity lies in further understanding the potential effects of non-traditional proteins on the gut microbiome, immunity, inflammatory conditions, DNA damage, cognition, and cellular ageing. Safety, sustainability, and evidence-based health research will be vital to the development of high-quality complementary protein foods that enhance human health at all life stages.

Serum Bilirubin Levels in Overweight and Obese Individuals: The Importance of Anti-Inflammatory and Antioxidant Responses

Obesity is a chronic condition involving low-grade inflammation and increased oxidative stress; thus, obese and overweight people have lower values of serum bilirubin. Essentially, bilirubin is a potent endogenous antioxidant molecule with anti-inflammatory, immunomodulatory, antithrombotic, and endocrine properties. This review paper presents the interplay between obesity-related pathological processes and bilirubin, with a focus on adipose tissue and adipokines. We discuss potential strategies to mildly increase serum bilirubin levels in obese patients as an adjunctive therapeutic approach.

Qualitative and Quantitative Assessment of Buckwheat Husks as a Material for Use in Therapeutic Mattresses

Buckwheat husks are used in many therapeutic products such as pillows, mattresses, seats, etc. This material is proposed by producers for example for discopathy, back pain and head vasomotor disorders. Our studies evaluated the impact of using cotton mattresses with buckwheat husk fillings on people's health condition. The main research was carried out on the group of 60 people divided into 3 groups (1-people with skeletal system problems, 2-people spending a lot of time lying with the probability of pressure ulcer formation and 3-healthy people). In addition, different tests have been carried out on the possibility of colonization of mattresses by fungi, bacteria and arthropod pests, and rheological, chemical and flammability tests. The research material in the form of buckwheat husks was tested in a diverse way. All tests indicate high usefulness of husks for therapeutic activity. This material was contaminated with fungi, bacteria and pests at a very low level, related to the natural colonization of buckwheat nuts during harvest and storage. The quality of the husks was also confirmed in rheological, chemical and flammability studies. Finally, this has also been confirmed in surveys conducted on people with health problems. The analyses show that the buckwheat husk is an excellent material that can be used to fill prophylactic mattresses. This has been confirmed by the results of laboratory tests and opinions of respondents using mattresses filled with buckwheat husk.

Probiotic-fermented black tartary buckwheat alleviates hyperlipidemia and gut microbiota dysbiosis in rats fed with a high-fat diet

Natural plants fermented with probiotics exert beneficial effects on hyperlipidemia and gut microbiota disorders. This study aimed to investigate the hypolipidemic activity of fermented black tartary buckwheat (FBTB) in rats with hyperlipidemia induced by a high-fat diet (HFD) in association with the regulation of gut microbiota. Probiotic fermentation by Bacillus sp. DU-106 obviously increased the contents of tyrosine, lysine, total flavonoids, total polyphenols, quercetin, and kaempferol in black tartary buckwheat (BTB) and significantly decreased the rutin content. FBTB treatment for 8 weeks significantly decreased the levels of serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol in HFD-induced hyperlipidemic rats. Western blot analysis further confirmed that the protein expression levels of FXR, SREBP1, and PPARα were altered after FBTB treatment. Moreover, FBTB intervention altered the gut microbiota of HFD-fed rats by increasing the relative abundances of Lactobacillus, Faecalibaculum, and Allobaculum and decreasing the relative abundance of Romboutsia. The relative abundance of Allobaculum was positively correlated with the levels of tyrosine, total flavonoids, total polyphenols, quercetin and kaempferol and negatively correlated with that of rutin. These results suggested that FBTB could alleviate hyperlipidemia and gut microbiota dysbiosis in HFD-fed rats.
