Food insecurity is a major issue in current scenario where a large section of mankind is at risk of insufficient diet. As food productivity has its limits, the prospecting of unutilized or underutilized flora as food candidates is collectively recognized as a sustainable option. In the past decade, a number of obscure plants have been identified to be rich in dietary components and deemed fit for integration into the food platter. This review discusses a candidate Salicornia, belonging to family Amaranthaceae...

Short-chain fatty acids (SCFAs), such as acetate, propionate, and butyrate, are produced predominantly by gut microbiota fermentation of dietary fiber. SCFAs are newly identified as endogenous ligands of two orphan G protein-coupled receptors, GPR41 and GPR43, which have the potential to modulate inflammation. Therefore, GPR41 and GPR43 may mediate the link between the gut microbiome status and various disease conditions including renal inflammation. This study aimed at investigating whether SCFAs activate GPR41 and GPR43, and thereby exert anti-inflammatory effects in human renal cortical epithelial cells (HRCEs) as a main component of kidney tissue...

Social welfare, better health care, and urbanization have greatly improved human health and well-being. On the other hand, Western societies suffer from the downsides of the elevated standard of living. Among other factors, the Western diet (poor in dietary fiber), lack of contact with natural biodiversity, and excessive antibiotic use are known to be associated with the increase in chronic inflammatory disorders. Limited exposure to microbial biodiversity, in combination with severe lifestyle-related disturbances to commensal microbial communities, especially during early life, is changing the diversity and composition of human microbiota...

The complex interactions between the diet, gut microbiome, and host characteristics that provide a functional benefit to the host are an area of great interest and current exploration in the nutrition and health science community. New technologies are available to assess mechanisms that may explain these functional benefits to the host. One emerging functional benefit from changes in the gut microbiome is increased calcium absorption, increased calcium retention, and improved indices of bone health. Prebiotic fibers enhance microbial fermentation in the gut, providing an ecological advantage to specific nonpathogenic bacteria that have the ability to modify an individual's metabolic potential...

BACKGROUND: Low circulating levels of sex hormone-binding globulin (SHBG) have been shown to be a direct and strong risk factor for type 2 diabetes, cardiovascular diseases, and hormone-dependent cancers, although the relation between various aspects of dietary carbohydrates and SHBG levels remains unexplored in population studies. METHODS: Among postmenopausal women with available SHBG measurements at baseline (n = 11,159) in the Women's Health Initiative, we conducted a comprehensive assessment of total dietary carbohydrates, glycemic load (GL), glycemic index (GI), fiber, sugar, and various carbohydrate-abundant foods in relation to circulating SHBG using multiple linear regressions adjusting for potential covariates...

FODMAP, "Fermentable Oligo-, Di- and Mono-saccharides And Polyols", is a heterogeneous group of highly fermentable but poorly absorbed short-chain carbohydrates and polyols. Dietary FODMAPs might exacerbate intestinal symptoms by increasing small intestinal water volume, colonic gas production, and intestinal motility. In recent years the low-FODMAP diet for treatment of irritable bowel syndrome (IBS) has gained increasing popularity. In the present review we aim to summarize the physiological, clinical, and nutritional issues, suggesting caution in the prolonged use of this dietary treatment on the basis of the existing literature...

PURPOSE: While the prevalence of children on vegetarian diets is assumed to be on the rise in industrialized countries, there are hardly any representative data available. In general, vegetarian diets are presumed to be healthy; nevertheless, there are concerns as to whether the dietary specifications required during infancy, childhood, and adolescence can be met. Therefore, the objective of this systematic review was to evaluate studies on the dietary intake and the nutritional or health status of vegetarian infants, children, and adolescents...

Storage related changes in the cell wall composition potentially affect the texture of plant-based foods and the physiological effects of cell wall based dietary fiber components. Therefore, a detailed characterization of cell wall polysaccharides and lignins from broccoli stems was performed. Freshly harvested broccoli and broccoli stored at 20°C and 1°C for different periods of time were analyzed. Effects on dietary fiber contents, polysaccharide composition, and on lignin contents/composition were much more pronounced during storage at 20°C than at 1°C...

The hippocampal formation undergoes significant morphological and functional changes after prolonged caloric and dietary restriction (DR). In this study we tested whether prolonged DR results in deleterious alterations in hippocampal neurogenesis, density of granule cell neurons and mossy fibers, all of which support plasticity in the dentate gyrus. Young adult animals either experienced free access to food (control condition), or every-other-day feeding regimen (DR condition) for 3 months. The number of Ki-67 cells and 28-day old 5-bromo-2'-deoxyuridine (BrdU) cells were quantified in the dorsal and ventral dentate gyrus to determine the effect of DR on cellular proliferation and survival of neural progenitor cells in the anatomically defined regions of the dentate gyrus...

Over the past decade, application of culture-independent, next generation DNA sequencing has dramatically enhanced our understanding of the composition of the gut microbiome and its association with human states of health and disease. Host genetics, age, and environmental factors such as where and who you live with, use of pre-, pro- and antibiotics, exercise and diet influence the short- and long-term composition of the microbiome. Dietary intake is a key determinant of microbiome composition and diversity and studies to date have linked long-term dietary patterns as well as short-term dietary interventions to the composition and diversity of the gut microbiome...
