  Related Articles Egg product freshness evaluation: a metabolomic approach. J Mass Spectrom. 2018 Jun 27;: Authors: Cavanna D, Catellani D, Dall'Asta C, Suman M Abstract Egg products freshness is a crucial issue for the production of safe and high quality commodities. Up to now this parameter is assessed with the quantification of few compounds but the possibility to evaluate more molecules simultaneously could help to provide robust results. In this study, 31 compounds responsible of freshness and not freshness of egg products were selected with a metabolomic...

Gastrointestinal stability of urolithins: an in vitro approach

Gastrointestinal stability of urolithins: an in vitro approach

Urolithins are bioactive ellagitannin-derived metabolites showing a wide phenotypic variation in their production by the gut microbiota. This work represents a first in vitro step toward the development of new strategies focused on the oral supplementation of urolithins with the aim of overcoming their selective production and making their putative health benefits available for the whole population. In order to study their gastrointestinal stability, urolithin A, urolithin B, and urolithin B-glucuronide, as well as ellagic acid, were subjected to a simulated gastrointestinal digestion model...

Bioaccessibility and bioavailability of phenolic compounds in bread: a review

Cereal-based products, like breads, are a vehicle for bioactive compounds, including polyphenols. The health effects of polyphenols like phenolic acids (PAs) are dependent on their bioaccessibility and bioavailability. The present review summarizes the current understanding of potential strategies to improve phenolic bioaccessibility and bioavailability and the main findings of in vitro and in vivo studies investigating these strategies applied to breads, including the use of raw ingredients with greater phenolic content and different pre-processing technologies, such as fermentation and...

Environmental impact of omnivorous, ovo-lacto-vegetarian, and vegan diet

Environmental impact of omnivorous, ovo-lacto-vegetarian, and vegan diet

Food and beverage consumption has a great impact on the environment, although there is a lack of information concerning the whole diet. The environmental impact of 153 Italian adults (51 omnivores, 51 ovo-lacto-vegetarians, 51 vegans) and the inter-individual variability within dietary groups were assessed in a real-life context. Food intake was monitored with a 7-d dietary record to calculate nutritional values and environmental impacts (carbon, water, and ecological footprints). The Italian Mediterranean Index was used to evaluate the nutritional quality of each diet. The omnivorous choice...

Rye polyphenols and the metabolism of n-3 fatty acids in rats: a dose dependent fatty fish-like effect

As long-chain fatty acids (LCFA) of the n-3 series are critically important for human health, fish consumption has considerably increased in recent decades, resulting in overfishing to respond to the worldwide demand, to an extent that is not sustainable for consumers’ health, fisheries economy, and marine ecology. In a recent study, it has been shown that whole rye (WR) consumption improves blood and liver n-3 LCFA levels and gut microbiota composition in rats compared to refined rye. The present work demonstrates that specific colonic polyphenol metabolites may dose dependently stimulate...

5-(3′,4′-Dihydroxyphenyl)-γ-valerolactone and its sulphate conjugates, representative circulating metabolites of flavan-3-ols, exhibit anti-adhesive activity against uropathogenic Escherichia coli in bladder epithelial cells

5-(3′,4′-Dihydroxyphenyl)-γ-valerolactone and its sulphate conjugates, representative circulating metabolites of flavan-3-ols, exhibit anti-adhesive activity against uropathogenic Escherichia coli in bladder epithelial cells

Urinary tract infections (UTI) are mostly caused by uropathogenic Escherichia coli (UPEC). Cranberry-based products have shown preventive effects against UTI, and this has been partially attributed to their A-type proanthocyanidin content. However, recent evidence reports phenyl-γ-valerolactones as the most relevant urinary metabolites of cranberry procyanidins, and candidates these compounds as plausible responsible for the protective effects of cranberries against UTI. This paper studied the inhibition of the adherence of UPEC ATCC®53503™ to T24 bladder epithelial cells by...

A comprehensive meta-analysis on dietary flavonoid and lignan intake and cancer risk: Level of evidence and limitations

To summarize available evidence on the association between dietary flavonoid as well as lignan intake and cancer risk in observational studies, a systematic search on electronic databases of all English language case–control and prospective studies published up to June 2016 was performed. Risk ratios (RRs) and 95% confidence intervals were calculated by random-effects model separately by study design. Heterogeneity and publication bias were tested. Out of the 143 studies included, meta-analyses of prospective studies showed isoflavones significantly associated with decreased risk of lung...
