The Relationship Between Dietary Patterns and the Epidemiology of Food Allergy
AI summary Read the abstract
This review explores why food allergies are increasing worldwide, particularly in urbanized societies, and how dietary patterns may play a role. The shift toward processed Western diets with less fiber appears to weaken the gut barrier and promote chronic inflammation, contributing to food allergy development. The authors note that environmental exposures including microplastics may also be significant factors, though more research is needed to determine their specific contribution.
Food allergies are increasing globally, particularly in Asia; however, the etiologies of allergic diseases remain poorly understood despite comprehensive studies conducted across a variety of populations. Epidemiological research demonstrates that food allergy is more prevalent in Westernized or urbanized societies than in rural or developing ones. As such, comparing the distribution and patterns of food allergies as well as the environmental exposures between regions may provide insight into potential causal and protective factors of food allergy. Diet is an important exposome that has been shown to modulate the immune system both directly and indirectly via pathways involving the microbiota. Changes in dietary patterns, especially the shift to a Westernized diet with reduced dietary fiber and an abundance of processed foods, impact the gut and skin epithelial barrier and contribute to the development of chronic inflammatory diseases, such as food allergy. Although dietary intervention is believed to have tremendous potential as a strategy to promote immunological health, it is essential to recognize that diet is only one of many factors that have changed in urbanized societies. Other factors, such as pollution, microplastics, the use of medications like antibiotics, and exposure to biodiversity and animals, may also play significant roles, and further research is needed to determine which exposures are most critical for the development of food allergies.

Intestinal barrier dysfunction and food allergy
AI summary Read the abstract
This review applies the epithelial barrier hypothesis to food allergy, arguing that environmental exposures including microplastics, nanoplastics, food additives, and detergents disrupt gut and skin barriers and drive the rise in allergic disease.
The interconnection between environment, immune-nutrition and allergic disease
AI summary Read the abstract
This review explores the connections between environmental factors, immune-nutrition, and the rising global prevalence of allergic diseases. The study discusses how climate change, air pollution, biodiversity loss, and environmental contaminants including microplastics contribute to immune dysregulation, and highlights the role of the microbiome and dietary factors in modulating allergic disease risk.
Epithelial barrier hypothesis: Effect of the external exposome on the microbiome and epithelial barriers in allergic disease
AI summary Read the abstract
This review proposes the 'epithelial barrier hypothesis,' which suggests that modern environmental exposures, including microplastics, air pollution, and processed food additives, are damaging the protective barriers of our skin, gut, and airways. When these barriers break down, foreign substances and bacteria can enter the body and trigger allergic and inflammatory diseases, which have been increasing rapidly in recent decades. The research suggests microplastics may be one of many environmental factors driving the rise in conditions like asthma, food allergies, and eczema.
Oral exposure to nano- and microplastics: Potential effects in food allergies?
AI summary Read the abstract
This review explored whether exposure to nano- and microplastics through food could contribute to the rising rates of food allergies worldwide. Researchers found that these tiny plastic particles may alter the structure of food allergens, increase gut permeability, promote intestinal inflammation, and disrupt the immune system. While direct evidence is still limited, the study suggests that microplastics in the diet could potentially heighten sensitivity to food allergens.
The potential of orally exposed risk factors and constituents aggravating food allergy: Possible mechanism and target cells
AI summary Read the abstract
This review examines how various orally consumed substances, including microplastics, nanoparticles, food additives, and pesticide residues, may worsen food allergies by disrupting the gut's protective lining. Researchers found that these risk factors can damage the intestinal epithelial barrier, allowing allergens to interact more easily with immune cells. The study highlights the need for further research into how everyday environmental and dietary exposures contribute to the rising rates of food allergy.
