Nutrigenomics and public health
Abstract Nutrigenomics (the study of the bidirectional interactions between genes and diet) is rapidly developing new bodies of knowledge that will change future research in human nutrition and public health. In fact, this new research topic is becoming essential in order to design and investigate the best dietary recommendations with the aim of preventing several diseases. In this regard, it is now recognized that dietary components can affect the phenotype by regulating gene expression. Although methylation is the widest modification mediated by diet components, recent literature has pointed out several other types of epigenetic modifications, such as regulations by noncoding RNAs and his…
Nutrition, public health, and sustainability: an overview of current challenges and future perspectives
Abstract Marked changes in the lifestyle of society over the past few years, both in developed and developing countries, lead to an increase in sedentary activities and the consumption of unhealthy diets. This is the main cause of the increase of malnutrition and overweight people worldwide that, in turn, lead to chronic diseases like obesity, metabolic syndrome, diabetes, and cardiovascular diseases that are of high public health concern. The aim of this chapter is to provide some advice for maintaining a healthy diet and the technologies that could be applied to achieve global food security in a sustainable way, and reducing food waste. On the other hand, the importance of bioactive compo…
Current and New Insights on Molecular Methods to Identify Microbial Growth in Fruit Juices
International audience; Identification of microorganisms in fruit juices plays an important role as it determines the viability of this food product from a commercial point of view. Several microorganisms use fruit as a substrate, thus causing spoilage and generating off‐flavors and odors. In addition, under favorable conditions, toxigenic fungi can produce mycotoxins in fruit juices. Conventional detection and enumeration of microorganisms using traditional plating assays are accurate and can detect low microbial contamination levels. However, in most cases they require long detection times. In recent years, the food industry has shown increased interest in developing new methods with incr…
New Trends in Molecular Techniques to Identify Microorganisms in Dairy Products
International audience; Dairy products constitute one of the most important types of functional foods. Most of these functional properties have been attributed to their complex microbial ecosystem. Moreover, microorganisms are responsible for the broad diversity of tastes, aromas, and textures of dairy products. For instance, many bacteria make a positive contribution to the organoleptic quality of cheeses or fermented milk. However, some other bacteria may have adverse effects, or may even present a health risk from a safety point of view. Thus, it is of a paramount importance to control microbial ecosystem of dairy products. Traditionally culture-based methods have been used for the ident…
