    Understanding the Kinetics of Nutrients Bioaccessibility by Modelling Foodomics Data

    Get PDF
    Holistic methods at the basis of the foodomics approach are allowing the in-depth understanding, at molecular and supramolecular level, of the complexity of food matrix. The latter, in turn, affects the nutrient bioaccessibility, one of the crucial factors impacting on the final effect of diets. However, many levels of complexity are emerging, relating to food-human interactions, while bolus descends along the whole gastrointestinal tract. Such complexity makes in-vitro and in-silico models still unable to fully describe intertwined kinetics between food matrix and human compartments. A possible framework to unravel complexity is outlined, starting from bioaccessibility modelling all the way down the to inter-compartmental kinetics. The aim is enhancing algorithms and models for prediction of the impact of a food category on a class of individuals. The proposed framework can consider many levels of complexity, provided that time-resolved experiments, suitable for integration with food matrix description, are correctly designed for this purpose

    Get PDF
    Hemp seed flour represents a potential ingredient for protein enrichment of gluten-free bakery products, the nutritional value of which could be further increased by fermentation with sourdough or with beneficial lactic acid bacteria strains. In this study, a metabolomic approach was used to evaluate the effect of hemp seed flour addition and sourdough fermentation on the production of flavoring and health-related volatile organic compounds (VOCs) in a gluten-free bread. Multivariate analysis of VOCs provided an in-depth description of the effects of hemp seed flour addition and sourdough fermentation on flavoring and bioactive compounds. In particular, an increased concentration of antimicrobial compounds, a larger spectrum of bioactive VOCs and a typical flavoring profile was evidenced in comparison to standard products. Furthermore, an increase of fermentation metabolites was observed in comparison to a standard dough, relating to abundances of 2-butanone-3-hydroxy, acetic acid, ethanol, and 1,4-butanediol. This study provides new insights on the evolution of flavoring and bioactive hemp seed flour constituents during sourdough fermentation, evidencing their retention in baked goods, and describes a new approach that could guide the formulation of innovative, fermented food with enhanced nutritional value

    This paper presents data on the influence of the use of a nutrition-information app (Edo) on healthy eating. The methodology adopted included a baseline (t0) and a follow-up online questionnaire (t1). The first survey was sent to 7000 consumers who had already downloaded the app. This survey collected data on users\u2019 perceived healthiness of their own diet, food purchasing habits, sociodemographic information, concern for appearance, perception of the Health Belief Model constructs, and objective and perceived healthy food knowledge. The follow-up survey (t1) was sent to the respondents who had used the app for 12 weeks. It collected data on app satisfaction, recommended additional app features, consumers\u2019 perception on the Health Belief Model constructs, and consumers\u2019 objective and perceived healthy food knowledge. Data elaboration included two factor analyses elaboration, one for t0 data and one for t1 data. The aim was the identification of constructs as latent factors of the data. The value of each construct was calculated and compared between t0 and t1. The data presented in this article can help the replication of studies about similar apps and enhance the cooperation among app developers, consumer behaviour scientists, nutritionists and marketing experts for apps development. For conclusion and interpretation of data, the original article can be consulted (DOI:10.1016/j.foodres.2019.108766)

    Importance of Coordinated Interactions of Multiple Stakeholders for Developing Products with Health Claims

    Get PDF
    During the development of products with health claims the collaboration and interaction of several disciplines and independent partners is necessary such as the production, quality, marketing, legal functions of the company, the external providers of the knowledge on the constituent having the claimed physiological effect, the clinics carrying out the human intervention studies, statisticians, laboratories providing testing services, etc. This results in a higher dependency from each other and less flexibility compared to the development of a conventional product where mostly in-company functions work together. Therefore systematic coordination of the multiple interactions, careful design of the product and its development process is particularly important

    The molecular mechanism of the cholesterol-lowering effect of dill and kale: The influence of the food matrix components

    open4noNome progetto: BASEFOOD (Sustainable exploitation of bioactive components from the Black Sea Area traditional foods)Foods are complex matrices containing many different compounds, all of which contribute to the overall effect of the food itself, although they have different mechanisms of action. While evaluating the effect of bioactive compounds, it is important to consider that the use of a single compound can hide the effects of the other molecules that can act synergistically or antagonistically in the same food. The aim of the present study was to evaluate the influence of food matrix components by comparing two edible plants (dill and kale) with cholesterol-lowering potential and similar contents of their most representative bioactive, quercetin. The molecular effects of the extracts were evaluated in HepG2 cells by measuring the expression of sterol-regulatory element-binding proteins (SREBPs), 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) and low density lipoprotein receptor (LDLR) at the mRNA and protein level. The results reported here show that both extracts reduced the cellular cholesterol level with a similar trend and magnitude. It is conceivable that the slightly different results are due to the diverse composition of minor bioactive compounds, indicating that only by considering food as a whole is it possible to understand the complex relationship between food, nutrition, and health in a foodomics vision.openDanesi, Francesca; Govoni, Marco; D'Antuono, Luigi Filippo; Bordoni, AlessandraDanesi, Francesca; Govoni, Marco; D'Antuono, Luigi Filippo; Bordoni, Alessandr

    Ancient wheat and health: a legend or the reality? A review on KAMUT khorasan wheat

    Get PDF
    After WWII, the industrialized agriculture selected modern varieties of Triticum turgidum spp. durum and spp. aestivum (durum wheat and common wheat) based on higher yields and technological characteristics. Nowadays, the use of whole ancient grains and pseudo cereals is considered nutritionally important. How ancient grains have positive effects is not entirely known, the fragmentation of the scientific knowledge being also related to the fact that ancient grains are not a homogeneous category. The KAMUT® trademark indicates a specific and ancient variety of grain (Triticum turgidum ssp. turanicum, commonly khorasan wheat), and guarantees certain attributes making studies sufficiently comparable. In this work, studies on KAMUT® khorasan wheat have been systematically reviewed, evidencing different aspects supporting its benefits. Although it is not possible to establish whether all ancient grains share these positive characteristics, in total or in part, this review provides further evidences supporting the consumption of ancient grains

    Antioxidative and anti-inflammatory effect of in vitro digested cookies baked using different types of flours and fermentation methods

    Get PDF
    There is an increased amount of evidence showing that consumption of whole grains and whole-grain-based products is associated with a reduction of the risk of developing many diseases, due mainly to the anti-inflammatory and antioxidative effects of their components.In this study, cookies, baked using different types of flours and fermentation methods, were digested in vitro and supplemented to cultured liver cells. Three different flours (ancient KAMUT® khorasan wheat grown in North America, ancient khorasan wheat grown in Italy, and modern durum wheat) and two different types of fermentation (standard and lactic fermentation) were used. This experimental design allowed us to supplement cells with a real food part of the human diet, and to consider possible differences related to the food matrix (types of flour) and processing (methods of fermentation). Cells were supplemented with the bioaccessible fractions derived from cookies in vitro digestion. Although results herein reported highlight the antioxidant and anti-inflammatory effect of all the supplementations, cookies made with khorasan flours appeared the most effective, particularly when the ancient grain was grown in North America under the KAMUT® brand. In light of the attempts to produce healthier food, this study underlines the importance of the type of grain to obtain baked products with an increased nutritional and functional value

    Understanding the gastrointestinal tract of the elderly to develop dietary solutions that prevent malnutrition

    Get PDF
    Although the prevalence of malnutrition in the old age is increasing worldwide a synthetic understanding of the impact of aging on the intake, digestion, and absorption of nutrients is still lacking. This review article aims at filling the gap in knowledge between the functional decline of the aging gastrointestinal tract (GIT) and the consequences of malnutrition on the health status of elderly. Changes in the aging GIT include the mechanical disintegration of food, gastrointestinal motor function, food transit, chemical food digestion, and functionality of the intestinal wall. These alterations progressively decrease the ability of the GIT to provide the aging organism with adequate levels of nutrients, what contributes to the development of malnutrition. Malnutrition, in turn, increases the risks for the development of a range of pathologies associated with most organ systems, in particular the nervous-, muscoskeletal-, cardiovascular-, immune-, and skin systems. In addition to psychological, economics, and societal factors, dietary solutions preventing malnutrition should thus propose dietary guidelines and food products that integrate knowledge on the functionality of the aging GIT and the nutritional status of the elderly. Achieving this goal will request the identification, validation, and correlative analysis of biomarkers of food intake, nutrient bioavailability, and malnutrition.info:eu-repo/semantics/publishedVersio

    Olive oil industry by-products. Effects of a polyphenol-rich extract on the metabolome and response to inflammation in cultured intestinal cell

    Get PDF
    Over the past years, researchers and food manufacturers have become increasingly interested in olive polyphenols due to the recognition of their biological properties and probable role in the prevention of various diseases such as inflammatory bowel disease. Olive pomace, one of the main by-products of olive oil production, is a potential low-cost, phenol-rich ingredient for the formulation of functional food. In this study, the aqueous extract of olive pomace was characterized and used to supplement human intestinal cell in culture (Caco-2). The effect on the cell metabolome and the anti-inflammatory potential were then evaluated. Modification in the metabolome induced by supplementation clearly evidenced a metabolic shift toward a “glucose saving/accumulation” strategy that could have a role in maintaining anorexigenic hormone secretion and could explain the reported appetite-suppressing effect of the administration of polyphenol-rich food. In both basal and inflamed condition, supplementation significantly reduced the secretion of the main pro-inflammatory cytokine, IL-8. Thus, our data confirm the therapeutic potential of polyphenols, and specifically of olive pomace in intestinal bowel diseases. Although intervention studies are needed to confirm the clinical significance of our findings, the herein reported results pave the road for exploitation of olive pomace in the formulation of new, value-added foods. In addition, the application of a foodomics approach allowed observing a not hypothesized modulation of glucose metabolism
