The bioavailability and metabolism of anthocyanins and ellagitannins following acute intake of grumixama fruit, native Brazilian cherry, by humans, and its in vitro antiproliferative activity against breast cancer cells (MDA-MB-231) were investigated. A single dose of grumixama juice was administered to healthy women (n = 10) and polyphenol metabolites were analyzed in urine and plasma samples collected over 24 h. The majority of the metabolites circulating and excreted in urine were phenolic acids and urolithin conjugates, the gut microbiota catabolites of both classes of polyphenols, respectively...

Cardiovascular diseases (CVDs) are one of the major causes of mortality and disability in Western countries. Prevention is known to be the cornerstone to lessen the incidence of CVDs and also to reduce the economic burden of both the citizen and the healthcare system. "Interventional medicine" certainly puts lifestyle modification as the first therapeutic step, including a healthy diet and physical activity. Secondly, a large body of research individuated a number of food and plant bioactives, which are potentially efficacious in preventing and reducing some highly prevalent CV risk factors, such as hypercholesterolemia, hypertension, vascular inflammation and vascular compliance...

The postprandial state plays a central role in the development and setting of chronic diseases. Condensed tannins (CT) are polyphenols with a known ability to modify carbohydrate digestion and absorption. The high concentration of CT in the pulp of carob fruit suggests a potential antidiabetic effect. The aim of this work was to analyze the in vitro and in vivo effects of carob fruit extract (CFE) on the digestion and absorption of carbohydrates. α-Glucosidase activity and glucose diffusion were tested in vitro using 0...

This study investigated the properties of polyelectrolyte complexes (PECs) fabricated by using ε-polylysine (EPL) and N,O-carboxymethyl chitosan (NOCC) and their potential applications in raw pork. The phase behaviors of PECs in aqueous solutions are characterized by the ζ-potential, mean radius and turbidimetric measurements. Stable colloidal and soluble PEC systems can be fabricated by carefully adjusting the mass ratio of NOCC to EPL. The minimum inhibitory concentration (MIC) assay showed that the colloidal and soluble PECs could maintain the antimicrobial activity of EPL in a laboratory medium...

The pandemic of vitamin D (VD) deficiency, and the global rise in obesity stimulate a need for staple low-fat foods and beverages enriched with VD. In light of consumer demand for a clean label, the use of natural endogenous food ingredients as delivery vehicles is of great interest. To this end, re-assembled casein micelles (rCM) have been shown to help retain VD during processing and shelf life and provide high bioavailability in low-fat milk and non-fat yoghurt. This follow-up study focused on the performance of VD-loaded rCM after drying and reconstitution, considering VD retention during simulated digestion, and the subsequent in vitro bioavailability of the vitamin...

We found that intraduodenal administration of l-ornithine (l-Orn) stimulates growth hormone (GH) secretion in Wistar rats, and then investigated its mechanism. GH-releasing activity after intraduodenal administration of l-Orn was blocked by [d-Lys(3)]-GHRP-6, an antagonist of the ghrelin receptor; however, l-Orn (100 μM) has no affinity for the ghrelin receptor, suggesting that the GH-releasing activity of l-Orn is mediated via ghrelin release and activation of the ghrelin receptor. Intraduodenally administered l-Orn increased ghrelin mRNA expression in the duodenum but not in the stomach or hypothalamus...

γ-Oryzanol is a natural antioxidant and nutraceutical compound, which makes it a good candidate for nutraceuticals, food supplements and pharmaceutical preparations. However, the incorporation of γ-oryzanol into aqueous formulations is rather difficult and its bioavailability can be severely decreased because of its water-insoluble property. In this study, γ-oryzanol-enriched nanoemulsion based fish oil and medium-chain triglyceride as carrier oils were proposed. The main objective was to optimize process parameters to form stable nanoemulsions and evaluate their physicochemical stability...

Stable oil foams with structured air-oil interfaces and high overrun (φair ≫ 0.5) were fabricated using edible emulsifiers (sucrose esters and lecithin). Advanced microscopy was used to understand the microstructure of these 'arrested' non-aqueous foams which displayed interesting rheological behaviour (yielding and thixotropy). Such complex colloids stabilized by edible ingredients could find important industrial applications in the development of novel textured food products.

Oxidative stress represents a disorder of the redox equilibrium between the production of free radicals and the capability of cells to eliminate them. As subversion of this redox balance is thought to initiate various diseases, living cells maintain a redox equilibrium diligently. More and more pieces of evidence show that oxidative stress has already become a common risk factor in the pathogenesis of neurodegenerative disorders. So, considerable importance has been given to the prevention of oxidative stress as a potential therapeutic strategy...

Sea buckthorn has long been used as a functional food to regulate cholesterol, relieve angina, and diminish inflammation. Flavonoids are one of the main active components in sea buckthorn. We investigated the effects of sea buckthorn flavonoid (SF) treatment on two pathways that mediate inflammation, the mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) pathways, to explore the anti-inflammatory activity of SFs in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. The LPS-induced over-production of nitric oxide (NO) and prostaglandin E2 (PGE2) was inhibited by SFs through a mechanism related to the modulatory effects of the inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) genes...
