Background/ObjectivesNutrient interactions in multi-ingredient supplements may influence absorption and bioavailability, yet pharmacokinetic data in this context remains limited. This clinical trial assessed the post-prandial absorption kinetics of key micronutrients in AG1, a comprehensive supplement containing vitamins, minerals, probiotics, and phytonutrients. MethodsIn a randomized, double-blind, placebo-controlled crossover trial 16 healthy adults (8 males and 8 females) consumed a single ...

BackgroundHuman milk (HM) bioactive components can have immune modulatory functions, impact the gut microbiome, and may result in functional benefits when added to infant formula (IF). In this single-arm, prospective, intervention study, we tested the effectiveness of an IF with a whey protein concentrate co-enriched in -lactalbumin, milk fat globule membrane (MFGM), and Sn-2 palmitate resulting in protein and lipid profiles observed in HM. The outcomes tested were feeding tolerance, Bifidobacte...

Outcomes from the COSMOS trial have reinforced the notion of flavanols as important plant-derived bioactives contributing to cardiovascular health. As discussions continue on whether specific dietary reference values for flavanols are warranted, it is possible that existing dietary guidelines emphasizing fruits and vegetables already yield sufficient flavanol intake levels. If this were the case, developing flavanol specific dietary reference values might be unnecessary. This study therefore aim...

IntroductionFiber intake is the most common nutritional inadequacy in the Western diet, with most adults consuming less than half of the recommended intake with only 5% of adults meeting the RDI. A novel, short-chain beta-glucan derived from oats (scOat Fiber), with improved solubility, low viscosity and enhanced palatability, compared to conventional oat fibers, was investigated for its benefits as a source of fiber supplementation. MethodsA 14-day pilot study evaluated the gastrointestinal to...

BackgroundCaloric restriction (CR) improves markers of biological aging, yet long-term effects on the human metabolome remain unclear. ObjectiveThis study examined the effects of CR (2 years) in healthy adults without obesity on circulating metabolites linked to aging and metabolic adaptations. MethodsUntargeted metabolomics was performed using fasted plasma samples collected at baseline, 12, and 24 months (BL, 12M, 24M) from CALERIE participants randomized to CR or ad libitum (AL) control. A ...

BackgroundTime-restricted eating (TRE) has gained popularity for weight loss and metabolic health. While some evidence suggests greater benefits when TRE aligns with circadian rhythms--characterized by early daytime eating and avoidance of nighttime intake, often referred to as early TRE (eTRE), other studies report no meaningful differences between eTRE, other TRE approaches with or without exercise, or calorie restriction (CR), and robust comparative evidence remains limited. AimTherefore, th...

BackgroundPrediabetes is associated with an increased risk of progression to type 2 diabetes. While dietary interventions in prediabetes traditionally primary focus on energy and macronutrient intake, the role of eating timing has recently been highlighted. This study aimed to examine the relationships between components of eating timing patterns and glycaemic parameters in prediabetes. MethodsIn 297 individuals with prediabetes, i.e. impaired fasting glucose or impaired glucose tolerance (age ...

BackgroundPacked lunches are a common feature of early childhood food provision, yet evidence describing their nutritional composition in early years settings remains limited. Understanding the foods provided during this developmental period is important, given the potential influence of early dietary exposures on later health. AimTo characterise the composition, nutritional quality, cost, and dietary patterns of packed lunches brought from home in Early Childhood Education and Care settings, a...

As plant-based (PB) diets become more common among UK children, understanding their nutritional adequacy and environmental impact is vital. This study assessed nutrient intake and dietary greenhouse gas emissions among children following omnivorous, vegetarian, and vegan diets. A cross-sectional analysis was conducted using three-day weighed food diaries from 39 UK children aged 2-12 years (omnivore n=15; and PB: vegetarian n=11; vegan n=13). Nutrients were analysed with and without supplementa...

IntroductionMechanistic research has shown that prior obesity induces durable transcriptomic and epigenetic reprogramming in adipose tissue that persists after weight loss and predisposes individuals to weight regain. This phenomenon, termed obesogenic memory (OM), is currently conceptualized primarily as a molecular process. We propose extending OM beyond adipose tissue biology to include interacting biological and sociocultural processes through which past exposures shape present physiological...

Maternal dietary diversity is vital for the health of both mothers and children during lactation, yet it is often compromised in low- and middle-income countries. This cross-sectional study among 251 lactating mothers in Tarakeswor Municipality, Nepal, assessed dietary diversity using a 24-hour dietary recall and the Minimum Dietary Diversity for Women (MDD-W) indicator. Overall, 68.1% of mothers achieved the minimum dietary diversity ([≥]5 of 10 food groups), with a mean score of 5.03 {+/-} ...

BackgroundObservational studies have linked high adherence to the "Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay" (MIND) diet to improved cognitive functions in older adults. The underlying peripheral and central mechanisms of this association remain poorly understood, although multiple nutrients in the MIND diet are known for their anti-inflammatory effects. Therefore, we explored the cross-sectional relation between MIND diet adherence (Dutch ve...

PurposeAdequate hydration is vital for health, yet many people do not meet fluid recommendations. This study aimed to characterise the role of water and sugar-sweetened beverages in hydration across different levels of socioeconomic status (SES) in the UK. MethodsIn a pre-registered cross-sectional study, participants (N = 1,112) recalled beverages consumed on the previous day and reported urine colour as an indicator of their hydration status. We analysed water intake (H1), sugar-sweetened bev...

Background/ObjectivesHuman lactoferrin (hLF) is glycoprotein of commercial interest as a food ingredient for gut health. Here, we report an exploratory analysis evaluating the effects of Helaina hLF (effera(R)), produced by Komagataella phaffii, on the adult gut microbiome and fecal metabolites in comparison to bovine LF (bLF). MethodsIn a randomized, double-blind, parallel-arm, controlled trial, 66 healthy adults received either high-dose (HD) effera(R) (3.4 g/day), low-dose (LD) effera(R) (0....

Opioid use disorder (OUD) has been linked to cardiometabolic diseases in adults through reductions in adiponectin--an adipocytokine with insulin-sensitizing effects. Opioid use during pregnancy dysregulates neonatal growth and may predispose to adult-onset diseases, but the impact of maternal OUD on neonatal adiponectin has not been studied. We hypothesize that maternal OUD also reduces adiponectin level in offspring (primary outcome) and alters growth (secondary outcome). To test our hypothesis...

The gut microbiota has been implicated in regulating body composition, insulin resistance, and energy metabolism through microbial metabolites, including short-chain fatty acids (SCFAs) and amino acids. However, evidence in adolescents, particularly regarding sex-specific differences and lifestyle such as alcohol intake, remains limited. Characterizing sex-specific metabolic signatures in adolescence may improve early identification of metabolic risk. To address this gap, we investigated associ...

Poor sleep is linked to consumption of sugary foods/beverages and high neural responsivity to palatable food cues. Yet, whether hedonic liking for sweet taste explains these associations remains unclear. We examined cross-sectional associations of five sleep traits (chronotype, sleep duration, insomnia frequency, snoring, daytime dozing) and a composite sleep score with sweet food liking, and total and free sugar intake in 76,734 UK Biobank participants (39-72 years, 56.3% female). Models adjust...

IntroductionThere is no comparison of iron phenotypes and menses, pregnancies, and live births reports of women with HFE-related hemochromatosis (HFE p.C282Y (rs1800562) homozygosity) and HFE wt/wt (absence of p.C282Y and HFE p.H63D (rs1799945)). Subjects and MethodsWe compared phenotypes and reports of non-Hispanic white women women aged [≥]25 y in post-population screening evaluations using univariable methods. ResultsThere were 153 p.C282Y/p.C282Y and 273 wt/wt. Median ages were 50 y (25...

BackgroundRandomized trials have shown that a healthy Nordic diet (HND) improves liver steatosis, but there is limited evidence on the effects of Nordic dietary patterns on the risk of major adverse liver outcomes (MALO). We specified a hypothetical target trial protocol to estimate the effects of adhering to a HND or the Nordic Nutrition Recommendations 2023 (NNR23) on the 24-year risk of MALO in a middle-aged to elderly Swedish population. MethodsTwo pooled population-based cohorts including ...

BackgroundThe surgical stress response is a predictable, physician-managed metabolic state triggered by anesthesia and tissue injury, marked by insulin resistance and hypercatabolism that create unique nutritional needs unmet by standard, pre-surgical fasting diets. We developed a multi-nutrient medical food to support perioperative metabolic homeostasis and piloted its safety/tolerability and exploratory outcomes. MethodsIn a single-center pilot trial (n=67) of adults undergoing elective abdom...
