Chengdeng Chi, Xiaoxi Li, Yiping Zhang, Ling Chen, Lin Li, Zhijiang Wang
The effects of non-covalent interactions between gallic acid (GA) and starch on starch digestibility and supramolecular structural changes (short-range ordered molecular structure, crystalline structure, lamellar structure and fractal structure) were investigated. The results indicated that the digestibility of both starches was substantially reduced in the rapidly digestible starch (RDS) content, but resistant starch (RS) was increased after interacting with GA. The RS content of starch-GA complexes ranged from 17...

Cocoa and its constituent bioactives (particularly flavanols) have reported anti-diabetic and anti-obesity activities. One potential mechanism of action is inhibition of dipeptidyl peptidase-IV (DPP4), the enzyme that inactivates incretin hormones such as glucagon-like peptide-1 and gastric inhibitory peptide. The objective of this study was to determine the DPP4 inhibitory activities of cocoas with different processing histories, and identify processing factors and bioactive compounds that predict DPP4 inhibition...

Food processing impacts both food structure and nutritional density. The effect of food structure on satiety and glycemic potentials is well recognized. However, the association between processing, satiety and glycemic potentials and nutrient profiles has not been much studied, especially in the diets of the elderly. Therefore, this study aimed at exploring relations between the level of food processing, consumption and nutrient profiles and satiety and glycemic potentials among 6686 French elderly people (≥65 years)...

Low-calorie sweeteners are considered to be beneficial in calorie control, but the impact of these sweeteners on gastric emptying is not well described. The purpose of this study was to compare the gastric emptying rate of agave nectar with those of glucose and fructose, and to evaluate the interaction of cholecystokinin (CCK)-1, CCK-2 and glucagon-like peptide-1 (GLP-1) receptors in agave-induced alterations in gastric emptying. Female Sprague-Dawley rats were fitted with gastric cannulas. Following the recovery, the gastric emptying rates of glucose, fructose and agave at 12...

Sesamol, a nutritional component from sesame, possesses antioxidant, lipid lowering and antidepressant activities. Nonetheless, few studies report its effects on high-energy-dense diet-induced cognitive loss. The present research aimed to elucidate the action of sesamol on high-fat and high-fructose (HFFD) "western"-diet-induced central nervous system insulin resistance and learning and memory impairment, and further determined the possible underlying mechanism. 3 month-old C57BL/6J mice were divided into 3 groups with/without sesamol in the drinking water (0...

In recent years, peptides derived from a variety of dietary proteins have been reported to exhibit inhibitory activity against the dipeptidyl-peptidase IV (DPP-IV) enzyme, a target in the management of type 2 diabetes. While much attention has been given to the production and identification of peptides with DPP-IV inhibitory activity from food proteins, particularly dairy proteins, little is known on the bioavailability of these molecules. In this study, the stability and transport of five previously identified milk-derived peptides (LKPTPEGDL, LPYPY, IPIQY, IPI and WR) and a whey protein isolate (WPI) digest with DPP-IV-inhibitory activity were investigated using Caco-2 cell monolayers as a model system for human intestinal absorption...

The protective role of glycine and glutamic acid against the toxic effects of oxidized oil was studied for the first time. Mustard seed oil was thermally oxidized and characterized for quality characteristics and polyphenolic composition using reversed phase HPLC-DAD. Significant changes in the quality characteristics occurred with thermal oxidation. Fourteen polyphenolic compounds were identified and quantified in oils. Quercetin-3-glucoside, quercetin-3-feruloylsophoroside, catechin, quercetin-3-rutinoside, quercetin-3,7-diglucoside, sinapic acid and vanillic acid hexoside were the major compounds in the fresh and oxidized oil...

There is limited information that relates the intake of food-derived bioactive peptides and the gut microbiota. We have previously described a pepsin hydrolysate of egg white (EWH) that ameliorates fat accumulation and dyslipidemia, while reducing oxidative stress and inflammation markers in obese Zucker rats. The aim of this study was to associate the beneficial effects of EWH with gut microbiota changes in these animals. Obese Zucker rats received daily 750 mg kg(-1) EWH in drinking water for 12 weeks and faeces were analysed for microbial composition and metabolic compounds in comparison with Zucker lean rats and obese controls...

The aim of the present paper was to determine, from four model cheeses differing in fat content and firmness and consumed by fourteen well characterised subjects, the respective impacts of in vivo aroma release, bolus rheology, chewing activity, mouth coating and salivary composition on dynamic aroma perception. The originality of the approach is that it considers all the parameters together and is able to evaluate their relative contribution using multi-block partial least square (MB-PLS) regression. The fruity aroma perception of the more hydrophilic compound (ethyl propanoate) was related to its dynamic release parameters before swallowing whereas the blue cheese aroma perception of the more hydrophobic compound (nonan-2-one) was related to its dynamic release parameters after swallowing and was highly impacted by mouth coating...

Gestational diabetes mellitus (GDM) is an increasingly serious health problem among pregnant women. Phytosterol-enriched spreads are known to reduce total cholesterol (TC) and low-density lipoprotein (LDL), but little is known about their effects on GDM. We aimed to examine the effect of the daily consumption of phytosterol-enriched spreads on both the maternal and neonatal outcomes of GDM patients. GDM patients during the third trimester of pregnancy were enrolled and assigned randomly to consume a regular spread or phytosterol-enriched spread daily until the end of their pregnancy...

Chronic inflammation disrupts intestinal barrier function and may contribute to the pathology of obesity and other diseases. The goal of this study was to determine the mechanism by which yogurt improves intestinal barrier function. Caco-2 cells were differentiated on Transwell inserts and used as a model of intestinal barrier permeability. Transepithelial electrical resistance (TEER) and flux of 4 kDa fluorescein isothiocyanate-dextran (FD) and lucifer yellow (LY) were used as indicators of monolayer integrity and paracellular permeability...

The positive health effects of phenolic compounds (PCs) have been extensively reported in the literature. An understanding of their bioaccessibility and bioavailability is essential for the elucidation of their health benefits. Before reaching circulation and exerting bioactions in target tissues, numerous interactions take place before and during digestion with either the plant or host's macromolecules that directly impact the organism and modulate their own bioaccessibility and bioavailability. The present work is focused on the gastrointestinal (GI) interactions that are relevant to the absorption and metabolism of PCs and how these interactions impact their pharmacokinetic profiles...

Excessive alcohol uptake exerts hepatocellular toxicity, ultimately leading to multiple liver diseases such as steatohepatitis and liver cirrhosis. Here, we aimed to explore the effects of mulberry leaf extract (MLE) and its major components chlorogenic acid (CGA) and neochlorogenic acid (nCGA) on alcoholic steatohepatitis. We determined the composition of MLE using liquid chromatography-mass spectrometric (LC-MS) analysis, which showed that MLE consisted of mainly chlorogenic acid derivatives and other polyphenols...

In this paper we investigate whether the Flory-Huggins theory can describe the thermodynamics of solutions of simple carbohydrates, like sugars and polyols. In particular, we focus on the description of the solubility of the carbohydrates in water. This is investigated for both binary and ternary mixtures, having two types of these carbohydrates. This research question arises especially in the case of bakery products, where one seeks to replace sucrose with other simple carbohydrates - which are often polyols...

The impact of flaxseed gum (FG) on the microrheological properties and physicochemical stability of whey protein isolate (WPI) stabilized β-carotene emulsions at pH 3.0 was studied. A layer-by-layer electrostatic deposition method was used to prepare multilayered β-carotene emulsions with interfacial membranes consisting of WPI and FG. The microrheological behavior of the multilayered β-carotene emulsions was measured through the diffusive wave spectroscopy technique. WPI alone and WPI-FG (concentration of FG = 0...

It is generally assumed that high-fat (HF) diets induce characteristic gene expression regulation, which may cause metabolic alterations associated with an increased risk of obesity, metabolic syndrome and other health alterations. However, an integrative analysis of the effects in different tissues is lacking, thus preventing new strategies to prevent or counteract permanent consequences. This review particularly focuses on lipid metabolism gene expression modulation in key homeostatic tissues in response to HF diet intake...

Current treatment strategies for inflammatory bowel diseases (IBDs) are associated with a lower efficacy and with several side effects that strongly affect the quality of life of IBD patients. Consequently, the development of new therapies, combining efficacy and safety is an important goal in the field of intestinal inflammation. In this context, evidence supports that polyphenols can be promising candidates due to their ability to modulate intracellular inflammatory signalling cascades. Luteolin, a naturally occurring flavonoid, exhibits anti-inflammatory properties in several models of inflammation...

Dietary l-arginine supplementation decreases backfat thickness and increases intramuscular fat content in growing-finishing pigs, but the underlying mechanisms are unknown. In this study, the effect of arginine on differentiation of porcine intramuscular preadipocytes was investigated in vitro. We showed that the mRNA and protein expressions of the peroxisome proliferator-activated receptor γ (PPARγ) and CCAAT/enhancer binding protein α were upregulated by arginine supplementation. Furthermore, the intracellular triglyceride level was increased by arginine supplementation...
