Influence of Age, Sex, and Diet on the Human Fecal Metabolome Investigated by 1 H NMR Spectroscopy
This study aimed to find the "absolute concentrations of fecal metabolites from 205 healthy Danes (105 males and 100 females, 49 ± 31 years old)". The results showed "The largest systematic variation was found to be highly related to age. Fecal concentrations of short-chain fatty acids (SCFA) were higher in the 18 years old group, while amino acids (AA) were higher in the elderly. Sex-related metabolic differences were weak but significant and mainly related to changes in SCFA. The concentrations of butyric, valeric, propionic, and isovaleric acids were found to be higher in males compared to females. Sex differences were associated with a stronger, possibly masking, the effect from differential intake of macronutrients. Dietary fat intake decreased levels of SCFA and AA of both sexes, while carbohydrate intake showed weak correlations with valeric and isovaleric acids in females''.
Fermentation of alginate and its derivatives by different enterotypes of human gut microbiota: Towards personalized nutrition using enterotype-specific dietary fibers
This study aims to understand "how different compositions of the microbiota may affect the fermentation of alginate, polyguluronate (PG) and polymannuronate acid (PM)". The results show "(...) Bacteroides-dominated microbiota (Bacteroides enterotype) is more proficient at degrading and utilizing PG and PM as compared to Prevotella-dominated (Prevotella enterotype) and Escherichia-dominated microbiota (Escherichia enterotype). (...) Our study demonstrates an enterotype-specific effect of microbiota on the fermentation of alginate and its derivatives and highlights that personalized nutrition using dietary fibers should be tailored according to individual's composition of the gut microbiome"
Sorting the Healthy Diet Signal from the Social Media Expert Noise: Preliminary Evidence from the Healthy Diet Discourse on Twitter
“Over 2.8 million people die each year from being overweight or obese, a largely preventable disease. Raised body weight indexes are associated with a higher risk of cardiovascular diseases, diabetes, musculoskeletal disorders, and some cancers. Social media has fundamentally changed the way we communicate, collaborate, consume, and create content. The ease with which content can be shared has resulted in a rapid increase in the number of individuals or organisations that seek to influence opinion and the volume of content that they generate. The nutrition and diet domain is not immune to this phenomenon. Unfortunately, from a public health perspective, many of these “influencers” may be poorly qualified to provide nutritional or dietary guidance and advice is given may be without accepted scientific evidence and contrary to public health policy. In this preliminary study, we analyse the ’healthy diet’ discourse on Twitter (...). Public health policymakers and professional nutritionists need to consider what interventions can be taken to counteract the influence of non-professional and bad actors on social media.”
Altered Fecal Microbiome Years after Traumatic Brain Injury
“Patients with chronic traumatic brain injury (TBI) requiring long-term, permanent care suffer a myriad of clinical symptoms (i.e., impaired cognition, fatigue, and other conditions) that persist for years beyond the acute brain injury. In addition to these comorbid clinical symptoms, chronic TBI patients exhibit altered amino acid and hormonal profiles with distinct cytokine patterns suggesting chronic inflammation. This metabolic link suggests a role of the gut-brain axis in chronic TBI. Thus, we utilized a two-site trial to investigate the role of the gut-brain axis in comorbidities of chronic TBI. The fecal microbiome profile of 22 moderate/severe TBI patients residing in permanent care facilities in Texas and California was compared to 18 healthy age-matched control subjects working within the participating facilities(...).The average chronic TBI patient fecal microbiome structure was significantly different compared to the control cohort, and these differences persisted after group stratification analysis to identify any unexpected confounders (...). Although the sequelae of gut-brain axis disruption after TBI is not fully understood, characterizing TBI-related alterations in the fecal microbiome may provide biomarkers and therapeutic targets to address patient morbidity.”
The trans-ancestral genomic architecture of glycemic traits
“Glycemic traits are used to diagnose and monitor type 2 diabetes and cardiometabolic health. To date, most genetic studies of glycemic traits have focused on individuals of European ancestry. Here we aggregated genome-wide association studies comprising up to 281,416 individuals without diabetes (30% non-European ancestry) for whom fasting glucose, 2-h glucose after an oral glucose challenge, glycated hemoglobin, and fasting insulin data were available. Trans-ancestry and single-ancestry meta-analyses identified 242 loci (99 novel; P < 5 × 10-8), 80% of which had no significant evidence of between-ancestry heterogeneity. Analyses restricted to individuals of European ancestry with equivalent sample size would have led to 24 fewer new loci. Compared with single-ancestry analyses, equivalent-sized trans-ancestry fine-mapping reduced the number of estimated variants in 99% credible sets by a median of 37.5%. Genomic-feature, gene-expression and gene-set analyses revealed distinct biological signatures for each trait, highlighting different underlying biological pathways. Our results increase our understanding of diabetes pathophysiology by using trans-ancestry studies for improved power and resolution.”
Contribution of genetic ancestry and polygenic risk score in meeting vitamin B12 needs in healthy Brazilian children and adolescents
This cross-sectional study included 168 children and adolescents, aged 9–13 years old. Total cobalamin was measured in plasma. Genotyping arrays and whole exome data were combined to yield ~ 7000 SNPs in 90 genes related to vitamin B12.
Vitamin B12 levels were driven by positive (EUR) and negative (AFR, AMR) correlations with genetic ancestry. A set of 36 variants were used to create a PRS that explained 42% of vitamin level variation. Vitamin B12 levels are influenced by genetic ancestry and a PRS explained almost 50% of the variation in plasma cobalamin in Brazilian children and adolescents.

Food & Consumer Trends
Food pairings 'ripe for innovation' as immunity mega-trend rolls on
Food synergies will be the next trend in the nutrition market, according to a report performed by AI data company Spoonshot. This can be done through the promotion of ingredients in packs to increase their benefits rather than focus only on a single ingredient. "Ingredient combinations that can enhance nutrient bioavailability will emerge alongside the single ingredient focus and pave the way for interesting innovation in the food and business space. As consumers become more interested in nutrition beyond just macronutrients, we expect to see a shift from the single "hero ingredients" call-outs to "dynamic duos". Another partnership that we may see is restaurants with nutritionists, "to use synergistic ingredient combinations to create dishes that enhance the bioavailability of nutrients, promoting benefits like immunity, gut health, eye health and so on".
“King of protein sources”: Dairy industry elaborates on trends and applications within performance nutrition
FrieslandCampina Ingredients, Fonterra, Arla Foods Ingredients, and Glanbia Nutritionals talk about dairy ingredients and the sports nutrition market tendencies. “Dairy continues to be the foundation of performance nutrition (...). The format and type...has changed, with high-protein products becoming more mainstream (...) dairy, and whey, in particular, continue to be the ‘king’ of protein sources in the performance space (...). “Dairy products that are spoonable and drinkable are a popular choice for athletes due to their ability to build a healthy gut microbiome, offering immune system benefits, as well as digestive and mental health support (...) [and] high-protein bakery products like cookies and brownies with a healthier positioning are set for growth". Amino acid ingredients, including BCAAs, EAAs and L-leucine, L-citrulline, and beta-alanine, are also the latest tendencies on the market.
