“…The uptake of amino acids depends on a variety of “amino acid transport systems” that preferentially transport amino acids of similar biophysical properties [ 16 , 17 ], whereas dipeptides and tripeptides are absorbed via the proton-dependent intestinal peptide transporter 1 (PEPT1) [ 18 ]. The large intestine hosts a diversity of gut bacteria, which are involved in the fermentation of products that escape digestion/absorption in the small intestine, such as dietary fibre, resistant starches and proteins, leading to the production of short-chain fatty acids (SCFAs) which can be absorbed through facilitated diffusion [ 19 , 20 , 21 ].…”

Enteroendocrine Hormone Secretion and Metabolic Control: Importance of the Region of the Gut Stimulation

It is now widely appreciated that gastrointestinal function is central to the regulation of metabolic homeostasis. Following meal ingestion, the delivery of nutrients from the stomach into the small intestine (i.e., gastric emptying) is tightly controlled to optimise their subsequent digestion and absorption. The complex interaction of intraluminal nutrients (and other bioactive compounds, such as bile acids) with the small and large intestine induces the release of an array of gastrointestinal hormones from specialised enteroendocrine cells (EECs) distributed in various regions of the gut, which in turn to regulate gastric emptying, appetite and postprandial glucose metabolism. Stimulation of gastrointestinal hormone secretion, therefore, represents a promising strategy for the management of metabolic disorders, particularly obesity and type 2 diabetes mellitus (T2DM). That EECs are distributed distinctively between the proximal and distal gut suggests that the region of the gut exposed to intraluminal stimuli is of major relevance to the secretion profile of gastrointestinal hormones and associated metabolic responses. This review discusses the process of intestinal digestion and absorption and their impacts on the release of gastrointestinal hormones and the regulation of postprandial metabolism, with an emphasis on the differences between the proximal and distal gut, and implications for the management of obesity and T2DM.

“…They include vitamins, minerals and bioactive substances such as phenolic compounds with antioxidant activity, which help the human body to fight the harmful effects of oxidative stress (Alì et al, 2021;Jiang et al, 2021;Singh et al, 2020). Dietary fibre, present in this type of foods is particularly important to the health of the gastrointestinal system and certain types of cancer (Gill et al, 2018;Johnson, 2005;Mao et al, 2021;McRae, 2018;Tang et al, 2013;Tomas et al, 2020;Wunjuntuk et al, 2022;Xu et al, 2018). Hence incentive the consumption of fibre rich foods is a way to improve the health of the general population.…”

This research work investigated the Lebanese consumers' knowledge about food fibre and their food habits according to age groups and gender. The study was conducted from January 2021 till end of March 2021. Due to the pandemic of Covid-19 and the lockdown, the questionnaire was administered randomly through social media. The survey consisted of a longitudinal study carried out on a non-probabilistic convenience sample of 258 Lebanese participants. The responses were used to undertake a quantitative, descriptive and analytical study. The questionnaires received and considered valid, were mostly from women (59.7%) and essentially living in an urban environment (78.3%). To analyse the data, basic descriptive statistics were considered on a first level. Additionally, statistical tests were also carried out (Student t test for comparisons between two groups). Finally, results and analysis were done to evaluate the importance of food knowledge among these people in addition to their eating habits and the possible gender differences. The results revealed that there are some gender inequalities (F=6.238, α= 0.0013) in terms of knowledge about food fibre, but no living environment differences were found (F=0.36, α=0.85). Additionally, consumption habits showed major differences between female and male food behaviour, especially when it comes to eating: the frequency of eating outside from home, eating fast food and consuming fruits. The value of this study focuses on the food knowledge and habits in Lebanon, specifically in a country defined by a multi-ethnical diversity and religiosity and where food habits were mainly related to social behaviour. Therefore, this study adds more knowledge about these people's food behaviour and valuable information about specific food attitudes.

“…One main compound that is removed during the refining of cereals is dietary fiber. Dietary fibers (e.g., β-glucans, arabinoxylans, resistant starch, and inulin) are a major contributor to several health benefits [ 58 , 59 ]. Fiber, defined by the EFSA as “non-digestible carbohydrates plus lignin” [ 60 ], has according to Directive 2008/100/EC “beneficial physiological effects such as: decreasing intestinal transit time, increasing stool bulk, fermentable by colonic microflora, reducing blood total cholesterol levels, reducing post-prandial blood glucose, or reducing blood insulin levels” [ 61 ].…”

Infant Cereals: Current Status, Challenges, and Future Opportunities for Whole Grains

Infant cereals play an important role in the complementary feeding period. The aim of this study was to review existing research about the quantity, type, and degree of infant cereal processing, with a special focus on whole grain infant cereals. Accumulating evidence shows many benefits of whole grain consumption for human health. Likewise, consumers are frequently linking the term whole grains to healthiness and naturality, and sustainable food production becomes a more important aspect when choosing an infant cereal brand. Whole grain cereals should be consumed as early as possible, i.e., during infancy. However, there are several challenges that food manufacturers are facing that need to be addressed. Recommendations are needed for the intake of whole grain cereals for infants and young children, including product-labeling guidelines for whole grain foods targeting these age stages. Another challenge is minimizing the higher contaminant content in whole grains, as well as those formed during processing. Yet, the greatest challenge may be to drive consumers’ acceptance, including taste. The complementary feeding period is absolutely key in shaping the infant’s food preferences and habits; therefore, it is the appropriate stage in life at which to introduce whole grain cereals for the acceptance of whole grains across the entire lifespan.
