SCOPE: α-Cyclodextrin (α-CD), a cyclic polymer of glucose, has been shown to lower plasma cholesterol in animals and humans; however, its effect on atherosclerosis has not been previously described. METHODS AND RESULTS: apoE-knockout mice were fed either low-fat diet (LFD; 5.2% fat, w/w), or Western high fat diet (21.2% fat) containing either no additions (WD), 1.5% α-CD (WDA); 1.5% β-CD (WDB); or 1.5% oligofructose-enriched inulin (WDI). Although plasma lipids were similar after 11 weeks on the WD vs...

Carotenoid dietary intake and their endogenous levels have been associated with a decreased risk of several chronic diseases. There are indications that carotenoid bioavailability depends, in addition to the food matrix, on host factors. These include diseases (e.g. colitis), life-style habits (e.g. smoking), gender and age, as well as genetic variations including single nucleotide polymorphisms that govern carotenoid metabolism. These are expected to explain interindividual differences that contribute to carotenoid uptake, distribution, metabolism and excretion, and therefore possibly also their association with disease risk...

SCOPE: D-chiro inositol (DCI), an isomer of inositol, possesses anti-oxidative and endothelial protective properties. The mechanism by which DCI prevents endothelial dysfunction was investigated, with emphasis on oxidative stress. METHODS AND RESULTS: DCI was found to inhibit NOX4 induction and enhance Nrf2 activity in palmitate (PA)-stimulated cells, showing that DCI prevents oxidative stress. DCI suppressed Ser616 phosphorylation and increased Ser637 phosphorylation of Drp1 and inhibited PA-induced mitochondrial fission...

SCOPE: Non-digestible oligosaccharides are used as prebiotics for perceived health benefits, among these modulating lipid metabolism. However, the mechanisms of action are incompletely understood. The present study characterized the impact of dietary ß-cyclodextrin (ßCD, 10%, w/w), a cyclic oligosaccharide, on sterol metabolism and reverse cholesterol transport (RCT) in conventional and also germ-free mice to establish dependency on metabolism by intestinal bacteria. METHODS AND RESULTS: In conventional ßCD-fed C57BL/6J wild-type mice plasma cholesterol decreased significantly (-40%, p<0...

Studies suggest diets rich in fruit and vegetables reduce bone loss, although the specific compounds responsible are unknown. Substrates for endogenous nitric oxide (NO) production, including organic nitrates and dietary nitrate, may support NO production in age-related conditions, including osteoporosis. We investigated the capability of dietary nitrate to improve NO bioavailability, reduce bone turnover and loss. Six-month-old Sprague Dawley rats [30 ovariectomized (OVX) and 10 sham-operated (sham)] were randomized into 3 groups: (1) vehicle (water) control, (2) low-dose nitrate (LDN, 0...

SCOPE: Fibroblast growth factor 21 (FGF21) is considered a promising therapeutic candidate for the treatment of obesity. Since FGF21 production is regulated by various nutritional factors, we analyze the impact of low protein intake on circulating levels of this growth hormone in mice and in a sub cohort of the PREDIMED (Prevención con Dieta Mediterránea) trial. We also describe the role of hepatic FGF21 in metabolic adaptation to a low-protein diet (LPD). METHODS AND RESULTS: We fed control and liver-specific Fgf21 knockout (LFgf21KO) mice a LPD...

Methylxanthines (MTXs) are consumed by almost everybody in almost every area of the world. Caffeine, theophylline and theobromine are the most well-known members of this family of compounds; they are present, inter alia, in coffee, tea, cacao, yerba mate and cola drinks. MTXs are readily absorbed in the gastrointestinal tract and are able to penetrate into the central nervous system, where they exert significant psychostimulant actions, which are more evident in acute intake. Coffee has been paradigmatic, as its use was forbidden in many diseases, however, this negative view has radically changed; evidence shows that methylxanthines display health benefits in diseases involving cell death in the nervous system...

SCOPE: In this study, we investigated the effect of aged garlic extract (AGE) on the high level of blood glucose in Tsumura Suzuki Obese-Diabetes (TSOD) mice. METHODS AND RESULTS: TSOD mice were fed standard diet with or without 2% AGE for 19 weeks. AGE treatment lowered the blood glucose level and significantly reduced the plasma level of glycated albumin in TSOD mice as compared with those without AGE treatment. In addition, AGE treatment increased the level of phosphorylated AMP-activated protein kinase (AMPK) in the adipose tissue, liver and muscle that played an important role in the maintenance of insulin sensitivity...

REVIEW
Shengmin Sang, YiFang Chu
Oats are a good source of soluble dietary fiber, especially β-glucan, which has outstanding functional and nutritional properties. β-Glucan is considered to be the major active component of oats because of its cholesterol-lowering and anti-diabetic effects. However, the nutritional benefits of oats appear to go beyond fiber to bioactive phytochemicals with strong antioxidant and anti-inflammatory effects. In this review, we summarize current knowledge on the chemistry, stability, bioavailability, and health effects of two unique phytochemicals in oats, avenanthramides (AVAs) and avenacosides A and B...

SCOPE: The role of invariant natural killer T cells in the development of non-alcoholic steatohepatitis (NASH) has not yet been fully understood. Here, the effect of the invariant natural killer T cell activator alpha-galactosylceramide (αGalCer) on the development of non-alcoholic fatty liver disease and intestinal barrier function was assessed in a mouse model of early Western-style diet (WSD)-induced NASH. METHODS AND RESULTS: Female C57BL/6J mice were either fed a liquid control diet or a liquid fructose-enriched WSD for 6 weeks while being treated 3-times weekly with αGalCer (2 μg i...

SCOPE: Functional foods can be used alone or in combination with existing therapies in preventing and treating type 2 diabetes (T2D). Trans-2,3,5,4'-tetrahydroxystilbene 2-O-β-glucopyranoside (trans-THSG), a dominant bioactive compound from Polygonum multiflorum (PM) - a popular medicinal food in Asia, has attracted increasing research interests due to its strong antioxidant activity. The content of naturally occurring cis-THSG (cis-2,3,5,4'-tetrahydroxystilbene 2-O-β-glucopyranoside) was very low in PM root, but was prepared in this research by mimicking the traditional process of PM...

SCOPE: Caffeine is one of the most frequently used psychoactive substances ingested mainly via beverage or food products. Major depressive disorder is a serious and devastating psychiatric disorder. Emerging evidence indicates that caffeine enhances the antidepressant-like activity of common antidepressant drugs in rodents. However, whether joint administration of low dose of caffeine enhances the antidepressant actions in depressed patients remains unclear. METHODS AND RESULTS: A total of 95 male inpatients were assigned to three groups and were asked to take either caffeine (60, 120mg) or placebo (soymilk powder) daily for 4 weeks on the basis of their current antidepressant medications...

SCOPE: We previously found that whole-grain (WG) rye porridges suppressed appetite and improved glucose metabolism. The present work aimed to investigate potential plasma metabolites that may be related to differences in those appetite and glucose responses. METHODS AND RESULTS: Twenty-one health subjects consumed six isocaloric breakfasts in a randomised cross-over study. Plain WG rye porridges (40 g and 55 g), rye porridge enriched with different inulin: gluten proportions (9:3 g; 6:6 g; 3:9 g), and a 55 g refined wheat bread (control) were served as part of complete breakfast, followed by a standardized lunch...

Creatine is a popular ergogenic supplement in sports nutrition. Yet, supplementation of creatine occasionally caused adverse effects such as gastrointestinal complaints, muscle cramps and an increase in body weight. Creatine monohydrate has already been evaluated by different competent authorities and several have come to the conclusion that a daily intake of 3 g creatine per person is unlikely to pose safety concerns, focusing on healthy adults with exclusion of pregnant and breastfeeding women. Possible vulnerable subgroups were also discussed in relation to the safety of creatine...

SCOPE: Zinc is an essential mineral that plays an important role in the body. We previously reported that orally feeding zinc-enriched yeast to mice induces non-rapid-eye-movement sleep. In addition, astaxanthin, an antioxidant abundant in seafood such as salmon and krill, is able to chelate minerals and may promote zinc absorption, which in return may also improve sleep. The purpose of our study was to examine the effect of zinc-rich and astaxanthin-containing food on sleep in humans...
