This study aimed to compare different methods to assess body fat (BF). We hypothesized that bioelectrical impedance analysis (BIA) or anthropometry may be used to estimate BF in prefrail older women, equivalently to dual-energy X-ray absorptiometry (DXA). The cross-sectional study included 72 prefrail community-dwelling older women (71.13 ± 4.65 years old; body mass index [BMI] 28.89 ± 4.23 kg/m2)

Although human clinical studies have suggested probiotic effects on blood glucose levels, knowledge about molecular mechanisms is still scarce. To test the hypothesis that selected Lactobacillus probiotic bacteria could regulate the activity of enterocyte glucose transporters, we aimed to measure in vitro effects of selected Lactobacillus probiotic bacteria on transcription and translation of intestinal

Alterations in gut endocrine cells and hormone levels have been measured in patients with irritable bowel syndrome (IBS). The hypothesis of the present study was that hormone levels would change after 4 weeks of a starch- and sucrose-reduced diet (SSRD) intervention corresponding to decreased carbohydrate intake and symptoms. Among 105 IBS patients from primary and tertiary healthcare, 80 were randomized

The association between frailty and obesity may differ according to the heterogeneity of body mass index (BMI) and waist circumference (WC) phenotypes in older adults. We hypothesized that the use of simple indicators of general and abdominal obesity combined, may more accurately represent obesity and allow to further elucidate on how frailty status and its criteria are related to obesity. A sample

Tea is a beverage commonly consumed worldwide. Matcha is a type of green tea produced by drying and grinding tea leaves (Camellia sinensis L.) into a fine powder. Matcha contains catechin, theanine, and caffeine, which affect cognitive function. Epidemiological studies conducted in Japan have shown that green tea consumption improves cognitive impairment. Previously, we found that daily matcha intake

The essential amino acid tryptophan (TRP) is discussed as a potential protective factor for physical and mental health. Besides positive effects via the microbiota of the gut on many physiological processes, TRP is the precursor of the neurotransmitter serotonin (5-HT), thereby playing a role for affective disorders. The present study investigated the effects of a TRP-rich diet on depressiveness and

The obesity epidemic has increased risk for non-alcoholic fatty-liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), advanced fibrosis and cirrhosis. We hypothesized that metabolic syndrome (MetS) severity would correlate with markers of NAFLD and NASH fibrosis. We evaluated cross-sectional data from 5,463 participants of the National Health and Nutrition Examination Survey 1999-2012, age 20-64

Although identification of population groups at high risk for low vitamin D status is of public health importance,there are no risk prediction tools available for children in Southern Europe that can cover this need. The present study aimed to develop and validate two simple scores that evaluate the risk for vitamin D insufficiency or deficiency in children. A cross-sectional epidemiological study

ELOVL fatty acid elongase 6 (ELOVL6) is a long-chain fatty acid elongase, and the hepatic expression of the Elovl6 gene and accumulation of triglycerides (TG) are enhanced by long-term high fructose intake. Fatty acid synthesis genes, including Elovl6, are regulated by lipogenic transcription factors, sterol regulatory element-binding protein 1c (SREBP-1c) and carbohydrate-responsive element-binding

Infancy may represent a sensitive window for establishing food preferences that could affect the individual's long-term potential to establish healthy eating patterns. Our study was based on the hypothesis that preserving the natural flavor of the ingredients of commercially prepared complementary foods would increase the acceptance of new foods, especially vegetables. Frozen vegetable-based meals

A significant number of pancreatic cancer cases are due to modifiable risk factors, with many being attributed to increased body fatness. This has sparked investigators to examine the role played by high dietary fat intake in pancreatic cancer development and the mechanisms driving this connection. However, there is currently no consensus on how dietary fat quantity and composition specifically affect

Metabolic Associated Fatty Liver Disease (MAFLD) is a range of hepatic disorders with progression to steatohepatitis with risk of development of fibrosis, cirrhosis, and hepatocellular carcinoma. MAFLD is strongly related to metabolic disorders of active fatty acids, which seem to be selective according to their specific ligand of G protein-coupled receptors (GPRs) located in immune response cells

Late-evening food intake is associated with cardiometabolic risk. We assessed the prevalence of late-evening and night-time eating in individuals with type 2 diabetes and its association with BMI and HbA1c. We hypothesized food intake during late evening and night-time to be prevalent among individuals with type 2 diabetes and to be associated with higher BMI and higher HbA1c. This cross-sectional

The hypothesis of this study is that weight-related behaviors such as weight perception and weight control efforts may be related to health indicators such as grip strength as an indicator of muscle strength. This cross-sectional study aimed to prove this hypothesis by assessment of the associations of perceived weight status, weight misperceptions, and weight control efforts with grip strength. A

This paper reviews studies that addressed the influence of diet on circadian rhythmicity in mice and, in turn, circadian clock chronodisruption and its role in the development of metabolic disorders. Studies from the past 14 years were selected via a systematic search conducted using the PubMed electronic database. After applying the inclusion and exclusion criteria, 291 studies were selected, of which

Vitamin D (VitD) possesses antiadipogenic and ergogenic properties that could be effective to counteract obesity-related adverse health consequences. Therefore, our overall hypothesis was that VitD could ameliorate obesity-induced insulin resistance, systemic inflammation, and loss of skeletal muscle mass and function in an obesity animal model, p62-deficient mice. Furthermore, it was hypothesized

This study aimed to investigate the effect of a 12-week very low-carbohydrate, high-fat (VLCHF) diet and exercise on biomarkers of inflammation in healthy individuals. Since the anti-inflammatory effects of a ketogenic diet have been established, we hypothesized that the VLCHF diet, along with exercise, would have an additional favorable effect on biomarkers of inflammation. Twenty-four healthy individuals

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease, and is characterized by the accumulation and presence of amyloid plaques (Aβ), tangles, dementia, and cognitive impairment. Currently, there is no known cure for AD; however, recently, the association between alteration of the gut microbiota and AD pathology has been explored to find novel therapeutic approaches. Microbiota-targeted

Vitamin D is a factor that regulates calcium and bone metabolism. However, the clinical effect of vitamin D on bone mineral density (BMD) remains controversial. We hypothesized that sufficient vitamin D level is required to maintain optimal BMD in adolescents. Based on Korea National Health and Nutritional Examination Survey, data of 1,063 adolescents aged 12-18 years were analyzed. The association

Vitamin D deficiency and a high-fat diet are considered health problems worldwide. The aims of this study were to examine the prevalence of vitamin D deficiency/insufficiency in young adults, factors related to the vitamin D status, and the influence of vitamin D deficiency and/or a high-fat diet on bone parameters. Here, we investigated the hypothesis that a high-fat diet in the presence of a vitamin

Deficiencies of many nutrients in pregnancy have adverse effects on fetal brain development with consequent impaired cognitive function in childhood. However, it is unclear whether deficiencies of vitamin B12 prenatally are harmful to the developing fetus. We therefore used the Avon Longitudinal Study of Parents and Children to test the hypothesis that cognitive outcomes in childhood are reduced if

The efficacy of weight loss interventions might be affected by the metabolic profile of adolescents with obesity. In this study, we hypothesize that the initial diagnosis of the MS, or its persistence after an intervention, will not reduce the efficacy of a 16-week multidisciplinary weight loss program. 92 adolescents (12-15 years; 62 girls) with obesity completed baseline anthropometric and body composition

Taste is a fundamental mechanism whereby compounds are detected orally, yet it is highly variable among individuals. The variability in taste that is attributable to genetics is not well-characterized despite its potential role in food selection and therefore eating habits that contribute to risk of overweight and obesity. In order to implicate measures of taste function and preference as potentially

It was our hypothesis that foods high in polyphenols and fiber have prebiotic activity. This human intervention study aimed to determine if daily consumption of freeze-dried California strawberry powder (SBP) leads to changes in the intestinal microbiota, fecal cholesterol and bile acid (BA) microbial metabolites. Fifteen healthy adults consumed a beige diet+26 g of SBP for 4 wks, followed by 2 wks

The dramatic increase of people affected by obesity worldwide seems to be influenced by external factors independent of eating habits, physical exercise, or genetic characteristics. There may be a number of such factors, but one hypothesis is that there is person-to-person transmission, causing an epidemic effect, as occurs with infectious diseases. In animal models, experimental infection with human

Docosahexaenoic acid (DHA) is one of the most important fatty acids that play a critical role in maintaining proper brain function and cognitive development. Deficiency of DHA leads to several neurodegenerative disorders and, therefore, dietary supplementations of these fatty acids are essential to maintain cognitive health. However, the complete picture of how DHA is incorporated into the brain is

Regular almond consumption has been shown to improve body weight management, lipid profile and blood glucose control. We hypothesized that almond consumption would alter fecal microbiota composition, including increased abundance and activity of potentially beneficial bacterial taxa in adults who are overweight and obese with elevated fasting blood glucose. A total of 69 adults who were overweight

To assess the intake of nutrients in people with Multiple Sclerosis (pwMS) compared to a control population, and to assess the pro/ anti-inflammatory properties of nutrients/ foods and their relationships with fatigue and quality of life. This was a cross sectional study in which 2410 pwMS (686 men; 1721 women, 3 n/a, mean age 53 (11 yrs)) provided dietary data using a Food Frequency Questionnaire

Retrospective chart reviews have reported hypophosphatemia associated with elemental formula use in infants and children with systemic disease involving multiple diagnoses. The present study aims to evaluate the bioavailability of phosphorus from two commercial elemental formulas and to test our hypothesis of bioequivalence of the two products in healthy volunteers receiving gastric acid-suppressive

Increasing evidence suggests that adipokines leptin and adiponectin, produced and secreted by adipocytes, are involved in regulating systemic inflammation and may be important targets for interventions reducing the chronic systemic inflammation linked to some conditions common in aging (e.g., atherosclerosis). Lower leptin levels and higher adiponectin levels in peripheral circulation have been associated

L-carnitine is an indispensable metabolite facilitating the transport of fatty acids into the mitochondrial matrix and has been previously postulated to exert a nutrigenomic effect. However, the underlying molecular mechanisms remain mostly unclear. We hypothesized that L-carnitine interacts with nuclear receptors involved in metabolic regulation, thereby modulating downstream targets of cellular metabolism

Alcohol misuse is a risk factor for many adverse health outcomes. Alcohol misuse has been associated with an imbalance of gut microbiota in preclinical models and alcoholic diseases. We hypothesized that daily alcohol use would change the community composition and structure of the human colonic gut microbiota. Thirty-four polyp-free individuals donated 97 snap-frozen colonic biopsies. Microbial DNA

Bariatric surgery is a metabolic surgery known to be an efficient treatment for weight loss, with adequate long-term maintenance. Interestingly, some studies have reported a reduction in branched chained amino acids (BCAAs) after bariatric surgery, which putatively contributes to post-surgical metabolic improvement. The current systematic review and meta-analysis investigated the effect of bariatric

This study investigated 2 possible approaches to dietary control of acute postprandial responses to a rice-based meal under equicarbohydrate conditions: (1) a dried apple (DA) preload and (2) co-ingestion of vinegar-soaked DA. We hypothesized that both approaches would counteract hyperglycemia with no negative effect on satiety, possibly explained by an inhibitory effect on digestive enzyme activity

Dietary supplementation with calanus oil, a novel wax ester–rich marine oil, has been shown to reduce adiposity in high-fat diet (HFD)–induced obese mice. Current evidence suggests that obesity and its comorbidities are intrinsically linked with unfavorable changes in the intestinal microbiome. Thus, in line with its antiobesity effect, we hypothesized that dietary supplementation with calanus oil

Binge eating disorder (BED) is known as the most common eating disorder with both psychosocial and biological factors involved. In this regard, there is a need to recognize probable disturbances in substances involved in food intake regulation in BED. In this study, we hypothesized that the levels of endocannabinoids, fatty acid amid hydrolase (FAAH) gene polymorphisms, and appetite regulatory substances

This study examined whether an acute bout of resistance exercise (RE) attenuated postprandial responses to a high fat meal (HFM) similarly in younger versus older adult men, and probed relationships among skeletal muscle mass (SMM), age, the metabolic load index (MLI) response, and the improvement in the MLI elicited by RE versus CON. Eleven younger (24 ± 4y) and 9 older (61 ± 5y) men completed RE

Intake of dietary fiber may protect against colon cancer. The anticancer property is associated with an increased production of short chain fatty acids (SCFAs), including acetate, propionate and butyrate, during dietary fiber fermentation in the colon. However, the mechanisms remain to be determined. We hypothesized that butyrate exhibits a stronger inhibitory potential against colon cancer cell proliferation

Polymorphisms in FADS genes are associated with plasma long-chain polyunsaturated fatty acids (LC-PUFA) and modulate omega-6/omega-3 balance. We hypothesized that the FADS2 gene variants will be associated with lower product-to-precursor ratio in the fatty acid metabolic pathways. Thus, we explored FADS2 rs174593, rs174616, and rs174576 effects on plasma phospholipid fatty acid profile, markers of

The aim of this study was to describe and compare the mean usual dietary intakes of adults with type 1 diabetes (T1D) and without diabetes living in Australia. Our hypothesis was that adults with T1D have similar dietary intake profiles to adults without diabetes. Data from the National Nutrition and Physical Activity Survey 2011-2012, which formed part of the Australian Health Survey 2011–13, were

The pathology of osteoporosis is multifactorial, but a growing body of evidence supports an important role of the gut-bone axis, especially in bone loss associated with menopause, rheumatoid arthritis, and periodontal disease. Aberrant T cell responses favoring an increase in the ratio of T helper 17 cells to T regulatory cells play a critical role in the underlying etiology of this bone loss. Many

To individualize nutritional interventions for the prevention and treatment of malnutrition and sarcopenia, it is required to understand the nutritional needs of older adults. This study explores the nutritional needs of geriatric outpatients. We hypothesized that inadequate energy and protein intake is common in geriatric outpatients. Data were retrieved from 2 cohort studies encompassing community-dwelling

This pilot trial reports the effects of L-carnosine administration on autonomic nervous system performance, brain metabolism, and various patient- and clinician-reported outcomes in a case series of patients with multiple sclerosis (MS). We hypothesized that medium-term L-carnosine supplementation would improve selected patient- and clinician-reported outcomes in MS patients, with no negative effects

Lipid digestion is critical for infant development, and yet, the interconnection between lipid digestion and the microbiota is largely understudied. This review focuses on digestion of the human milk fat globule and summarizes the current understanding of the mechanisms underlying this process in infants. We first discuss the partial hydrolysis of milk fat in the stomach, which leads to rearrangement

Queen Garnet plum (QGP), known for its high levels of anthocyanins, is a hybrid of the Japanese plum developed in Queensland, Australia. Anthocyanins provide the red, blue, and purple pigments in plants with demonstrated beneficial health effects. This study hypothesized that low-dose anthocyanin QGP intake will have a significant positive effect on cognition, blood pressure, and gut microbiota in

Asthma in children is the most prevalent allergic disease worldwide that has become a major public health priority. The objective of this study was to examine the relationship between baseline serum vitamin D status, spirometry, and fractional exhaled nitric oxide levels (FeNO) in 64 Greek children with ‘mild asthma’ aged 5 to 12 years (51.6% male) in a dietary intervention study. We hypothesized that

We determined the effect of consuming low–glycemic index (LGI) skim milk compared to a high–glycemic index (HGI) sports drink following evening exercise on fat oxidation and blood lipids after a subsequent high-energy breakfast. We hypothesized that postexercise skim milk consumption, compared to sports drink, would increase fat oxidation and lower harmful blood lipid and glucose concentrations after

This small-scale randomized controlled study aimed to examine the effect of l-arginine supplementation on the human chorionic gonadotropin (hCG)–positive rate and clinical pregnancy rate (CPR) in women undergoing assisted reproductive technology (ART) treatment for 3 months. From November 2017 to March 2018, 120 patients aged less than 40 years and planning for egg retrieval for embryo transfer were

Non-alcoholic fatty liver(NAFLD) is prevalent in Asians despite the low obesity rate. We hypothesized that the haplotype of genetic variants in the 22q13 loci has a strong association with non-alcoholic fatty liver disease (NAFLD) that can be identified by genome-wide association study and that lifestyles may interact with the haplotype. We tested the hypothesis in middle-aged and elderly adults in

Glutamine and glucose are both oxidized in the mitochondria to supply the majority of usable energy for processes of cellular function. Low levels of plasma and skeletal muscle glutamine are associated with severe illness. We hypothesized that glutamine deficiency would disrupt mitochondrial integrity and impair cell function. C2C12 mouse myoblasts were cultured in control media supplemented with 5

Higher motivation could support to lead behavioral change for obese children and adolescents. This study aimed to evaluate the effects of a nutrition care process (NCP)–based intervention targeted on diet and weight status in moderate to severe obese children and adolescents in Korea. One hundred four subjects (mean age: 10.95 years, body mass index (BMI) ≥97th percentile of age-sex) participated in

Maternal fructose consumption during pregnancy and lactation is associated with metabolic dysregulation in offspring. We tested the hypothesis that fish oil (FO) supplementation during pregnancy and lactation improves fructose-induced metabolic dysregulation in postpartum dams and offspring mice. We therefore aimed to determine the effects of FO supplementation on metabolic disruption in neonatal mice

Low-grade inflammation is a suggested mechanism in the development of Metabolic Syndrome (MetS), and diet could act as a regulator. Therefore, we hypothesized that the cumulative DII exposure from diet during infancy through adulthood would be positively associated with the MetS and its components in young Mexican adults. 100 participants from the ELEMENT cohort were included in this analysis. The

Blood pressure (BP) responses to exercise yield prognostic information beyond resting BP. While habitual higher dietary protein intake is associated with reduced resting BP, few studies have assessed the impact of high-protein meals on acute BP and vasoactive biomarker responses to exercise. To test the hypothesis that consuming a higher-protein, lower fat meal (HP; 30 g protein, 17 g fat, 52 g carbohydrate)
