“…For fiber, in a retrospective cross‐sectional case–control study, Matano et al 93 noted that in Japanese adults on antihistamines with poor control of their chronic urticaria, total fiber intake was not significantly associated with Urticaria Control Test (UCT) score, although urticaria patients had significantly higher fiber intake than controls ( p = 0.01). The aforementioned study by Pretorius et al 89 found that higher maternal intakes of resistant starch were associated with higher odds of parent‐reported eczema (aOR 1.27 95% CI 1.09, 1.49, p < 0.01), doctor‐diagnosed eczema (aOR 1.19, 95% CI 1.01, 1.41, p = 0.04), and doctor‐diagnosed eczema in non‐sensitized infants (aOR 1.29, 95% CI 1.06, 1.57, p = 0.01).…”

Recent decades have seen a rapid increase in chronic inflammatory disorders due to inappropriate or misdirected immune responses accompanied by insufficient development of immune regulatory networks. It is generally accepted that changes in environment, lifestyle, and dietary factors may play a role in the miseducation or deficient training of the immune system. 1-3 A shift away from traditional diets rich in plant-based foods to highly processed foods is thought to be particularly important for negatively affecting microbiome diversity and composition, species-specific characteristics, microbial metabolism, and immunological tolerance. 4,5 While we acknowledge that a range of nutritional factors may play a role in influencing immune function and immune regulation, in this review we will focus specifically on one dietary component-fiber.Dietary fiber is a complex dietary component, including carbohydrate polymers and oligomers, which makes up the non-digestible components of food. 6,7 All dietary fibers resist digestion in the small bowel and pass into the large bowel intact but differ in their physiochemical characteristics (e.g., solubility, viscosity, and fermentability), which determine their functionality in the gut and to what degree they are accessible by microbes. Most soluble fibers can be fermented by the gut microbiota, partially or completely, dependent on their chemical structure. Dietary fibers can be defined on the basis of their chemical compounds, on the basis of their functional compounds, or both. Slight differences in definitions of dietary fibers exist due to the wide range of non-digestible fibers that occur in nature. The European Food Safety Authority (EFSA) defines dietary fiber as "non-digestible carbohydrates plus lignin." 8 These include non-starch polysaccharides (NSP) cellulose, hemicelluloses, pectins, hydrocolloids (i.e., gums, mucilages, and β-glucans), resistant oligosaccharides, resistant starch (consisting of physically enclosed starch, some types of raw starch granules, retrograded amylose, chemically and/or physically modified starches), and lignin associated with the dietary fiber polysaccharides (Table 1).Prebiotics are often equated with dietary fibers, but only a subset of dietary fibers qualifies as prebiotics. Not all fibers are equally fermentable by the gut microbiota (Table 1), with considerable inter-individual variation in the potential in vivo fermentability of dietary fiber. [9][10][11] The term "prebiotic" was first defined by Gibson and Roberfroid over 25 years ago as "a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improving host health." 12 This definition has evolved to a more simplified version-"a substrate that is selectively utilized by host microorganisms conferring a health benefit." 13 The most common prebiotic fermentable fibers that have been studied for immune health benefits to date include inulin, fructo-oligosacc...

Modulation of the allergic immune response through alternative therapies is a field of study that aims to address allergic reactions differently from traditional approaches. These therapies encompass the utilization of natural functional foods, which have been observed to exert an influence on the immune response, thus mitigating the severity of allergies. Indeed, some studies suggest that the incorporation of these nutraceuticals can regulate immune function, leading to a reduction in histamine release and subsequent alleviation of allergic symptoms. Moreover, certain herbs and dietary supplements, such as curcumin, are believed to possess anti-inflammatory properties, which may serve to moderate allergic responses. Although the results remain somewhat mixed and require further research, these alternative therapies exhibit the potential to impact the allergic immune response, thereby providing complementary options to conventional treatments. Therefore, in this review, we aim to provide an updated account of functional foods capable of modulating the immune response to allergies. In that sense, the review delves into functional foods sourced from plants (phytochemicals), animals, and marine algae. Emphasis is placed on their potential application in the treatment of allergic disorders. It also provides an overview of how these foods can be effectively utilized as functional foods. Additionally, it explores the molecular mechanisms and scientific validity of various bioactive natural compounds in the management of allergies.

Microbial metabolism of specific dietary components, such as fiber, contribute to the sophisticated inter-kingdom dialogue in the gut that maintains a stable environment with important beneficial physiological, metabolic, and immunological effects on the host. Historical changes in fiber intake may be contributing to the increase of allergic and hypersensitivity disorders as fiber-derived metabolites are evolutionarily hardwired into the molecular circuitry governing immune cell decision making processes. In this review, we highlight the importance of fiber as a dietary ingredient, its effects on the microbiome, its effects on immune regulation, and potential mechanisms for dietary fibers in the prevention and management of allergic diseases. In addition, we review the human studies examining fiber or prebiotic interventions on asthma and respiratory outcomes, allergic rhinitis, atopic dermatitis, and overall risk of atopic disorders. While exposures, interventions and outcomes were too heterogeneous for meta-analysis, there is significant potential for using fiber in targeted manipulations of the gut microbiome and its metabolic functions in promoting immune health.
