Nutritional requirements for maintaining metabolic health may vary with each life stage, such as young, middle, and old age. To investigate the appropriate ratio of nutrients, particularly proteins, for maintaining metabolic health while approaching old age, young (6-month-old) and middle-aged (16-month-old) mice were fed isocaloric diets with varying protein percentages (5%, 15%, 25%, 35%, and… Continue reading Moderate protein intake percentage in mice for maintaining metabolic health during approach to old age

Dietary flavanols restore hippocampal-dependent memory in older adults with lower diet quality and habitual flavanol consumption
Dietary flavanols are food constituents found in certain fruits and vegetables that have been linked to cognitive aging. Previous studies suggested that consumption of dietary flavanols might specifically be linked to the hippocampal-dependent memory component of cognitive aging and that memory benefits of a flavanol intervention might depend on habitual diet quality. Here, we tested… Continue reading Dietary flavanols restore hippocampal-dependent memory in older adults with lower diet quality and habitual flavanol consumption
Excess dietary sugar alters colonocyte metabolism and impairs the proliferative response to damage
BackgroundThe colonic epithelium requires continuous renewal by crypt resident intestinal stem cells (ISCs) and transit amplifying (TA) cells to maintain barrier integrity, especially after inflammatory damage. The diet of high-income countries contains increasing amounts of sugar, such as sucrose. ISCs and TA cells are sensitive to dietary metabolites, but whether excess sugar affects their function… Continue reading Excess dietary sugar alters colonocyte metabolism and impairs the proliferative response to damage
Higher intake of dietary flavonols, specifically dietary quercetin, is associated with lower odds of frailty onset over 12 years of follow-up among adults in the Framingham Heart Study
BackgroundPolyphenolic antioxidants derived from plant foods may reduce oxidative stress and frailty, but the effect of the polyphenol subclass of dietary flavonoids and their subclasses on frailty is uncertain.ObjectivesTo determine the association between dietary flavonoids, their subclasses, quercetin (a specific flavonol), and frailty onset in adults.MethodsThis prospective cohort study included individuals from the Framingham Heart… Continue reading Higher intake of dietary flavonols, specifically dietary quercetin, is associated with lower odds of frailty onset over 12 years of follow-up among adults in the Framingham Heart Study
Imagined eating – An investigation of priming and sensory-specific satiety
While obesity remains a pressing issue, the wider population continues to be exposed to more digital food content than ever before. Much research has demonstrated the priming effect of visual food content, i.e., exposure to food cues increasing appetite and food intake. In contrast, some recent research points out that repeated imagined consumption can facilitate… Continue reading Imagined eating – An investigation of priming and sensory-specific satiety
High ultra-processed food consumption is associated with elevated psychological distress as an indicator of depression in adults from the Melbourne Collaborative Cohort Study
BackgroundFew studies have tested longitudinal associations between ultra-processed food consumption and depressive outcomes. As such, further investigation and replication are necessary. The aim of this study is to examine associations of ultra-processed food intake with elevated psychological distress as an indicator of depression after 15 years.MethodData from the Melbourne Collaborative Cohort Study (MCCS) were analysed (n = 23,299).… Continue reading High ultra-processed food consumption is associated with elevated psychological distress as an indicator of depression in adults from the Melbourne Collaborative Cohort Study
Efficacy of vitamin D3 supplementation on cancer mortality: Systematic review and individual patient data meta-analysis of randomised controlled trials
AbstractTo evaluate the effect of vitamin D3 supplementation on cancer mortality in the general population and on prognosis in cancer patients, a systematic review and meta-analysis of randomised, placebo-controlled trials (RCTs) and individual patient data (IPD) was conducted. Overall, 14 RCTs with a total of 104,727 participants (2015 cancer deaths) were identified and 7 RCTs, including… Continue reading Efficacy of vitamin D3 supplementation on cancer mortality: Systematic review and individual patient data meta-analysis of randomised controlled trials
High fried food consumption impacts anxiety and depression due to lipid metabolism disturbance and neuroinflammation
To address a crucial knowledge deficiency concerning the correlation between fried food consumption and the risk of anxiety and depression, here we revealed that frequent fried food consumption is strongly associated with a higher risk of anxiety and depression. Notably, acrylamide is a representative contaminant in fried foods, thereby further elucidating its toxicological mode of… Continue reading High fried food consumption impacts anxiety and depression due to lipid metabolism disturbance and neuroinflammation
Effect of walnut consumption on neuropsychological development in healthy adolescents: a multi-school randomised controlled trial
BackgroundOmega-3 fatty acids are critical for neuropsychological functioning. Adolescence is increasingly believed to entail brain vulnerability to dietary intake. The potential benefit on adolescent neurodevelopment of consuming walnuts, a source of omega-3 alpha-linolenic acid (ALA), remains unclear.MethodsWe conducted a 6-month multi-school-based randomised controlled nutrition intervention trial to assess whether walnut consumption has beneficial effects on… Continue reading Effect of walnut consumption on neuropsychological development in healthy adolescents: a multi-school randomised controlled trial
