Higher consumption of ultra-processed food by pregnant women was linked to an increased risk of infantile atopic dermatitis within the first year of life.
The research used 861 pairs of pregnant women and their offspring from the Mothers' and Children's Environmental Health project in Korea. These women’s dietary intake was measured using the 24-hour recall method during 12-28 weeks gestation. Foods were classified as ultra-processed following the NOVA classification and their consumption was calculated as the proportion of total energy intake, with participants categorized into quartiles. The prevalence of infantile atopic dermatitis was assessed based on their medical histories and according to the International Study of Asthma and Allergies in Childhood criteria.
The results revealed that children born to mothers in the highest quartile of ultra-processed food consumption, compared to the lowest quartile, showed a higher risk towards atopic dermatitis within 12 months. This relationship became stronger after adjusting for certain confounding variables. Additionally, the link stayed consistent even after adjusting based on the Korean Healthy Eating Index, which measures diet quality.

Chinese herbal medicine (CHM) improved AD symptoms but had no significant impact on patients' quality of life or IgE levels suggesting CHM's potential as an AD treatment with further research.

Systematic Review Eczema
CHM showed benefits in improving AD symptoms, such as itching and skin appearance, compared to placebos. However, it didn't significantly affect patients' quality of life or IgE levels. CHM was safe, with only minor side effects. These findings suggest CHM could be a useful treatment for AD, but more standard guidelines are needed due to variations in herbal ingredients and dosages in different studies.
Higher consumption of ultra-processed food is linked to an increased risk of developing Crohn's disease, with no consistent connection observed with ulcerative colitis.

Cohort Study Ulcerative Colitis Ultra-Processed Foods
A prospective cohort study was conducted using three nationwide cohorts of health professionals in the United States. The study utilized self-reported consumption of ultra-processed foods to assess its association with the risk of Crohn's disease and ulcerative colitis. It involved 245,112 participants and spanned several years of observation. The analysis primarily leveraged Cox proportional hazards models to estimate hazard ratios for Crohn's disease and ulcerative colitis while adjusting for potential confounding factors.
The study observed a total of 369 cases of Crohn's disease and 488 cases of ulcerative colitis over the period of follow-up. The participants in the highest quartile of ultra-processed food consumption experienced a noteworthy surge in the risk of developing Crohn's disease. Ultra-processed breads, breakfast foods, frozen or shelf-stable ready-to-eat or heat meals, and certain spreads and gravies showed the strongest positive correlations with Crohn's disease risk. However, no clear association was seen between ultra-processed food intake and the incidence of ulcerative colitis.
Oral administration of Tremella fuciformis polysaccharides may constitute a new, effective therapy for Atopic dermatitis, improving both immune response and intestinal microbiota.
2022 Frontiers in Pharmacology Tremella fuciformis polysaccharides alleviate induced atopic dermatitis in mice by regulating immune response and gut microbiota Xie L, Yang K, Liang Y, Zhu Z, Yuan Z, Du Z
Experimental Study Eczema Gut Microbiota Polysaccharides
In the methodology of this study, the therapeutic effects of Tremella fuciformis polysaccharides (these have multiple biological activities), on Atopic dermatitis, were examined through both topical application and oral administration on mice induced with Atopic dermatitis-like disorder. The changes across transdermal water loss, epidermal thickening, and ear edema in the affected mice were observed. Notably, the study also considered the polysaccharides' impacts on the proportion of specific regulatory T cells in the mesenteric lymph nodes of the mice.
The results showed that both therapeutic methods positively impacted the conditions of the affected mice, with oral administration offering superior efficacy over topical application. The oral administration of the polysaccharides led to an increase of specific regulatory T cells, evidence of immune regulation. Further, non-targeted metabolomics and sequencing of certain DNA amplicons pointed towards observable modulation in fecal metabolites and a changed composition of gut microbiota in the mice following the oral treatment.
Honey, traditionally a food item, exhibits therapeutic properties—anti-microbial, anti-inflammatory, anti-cancer, and wound healing—showing promise in managing and preventing allergic diseases, as supported by scientific evidence and clinical studies.
2021 Frontiers in Pharmacology The Potential use of Honey as a Remedy for Allergic Diseases: A Mini Review Aw Yong PY, Islam F, Harith HH, Israf DA, Tan JW, Tham CL
Review Article Allergy Eczema Honey
This mini review explores honey's transition from a conventional food to a potential treatment for allergic diseases. Emphasis is placed on its diverse therapeutic properties, particularly its ability to alleviate pathological conditions and regulate inflammatory cell recruitment in cellular and animal models.
Scientific evidence and clinical studies suggest that honey holds potential in relieving allergic symptoms, offering a promising treatment or preventive approach for allergic diseases such as anaphylaxis, asthma, and atopic dermatitis. The review provides valuable insights for considering honey in clinical settings for allergic disease management.
Traditional Chinese Medicine, specifically acupuncture, demonstrates promising effects in managing allergic diseases like allergic rhinitis and asthma.
2020 Current Allergy and Asthma Reports Traditional Chinese Medicine (TCM) and Allergic Diseases Chan HHL, Ng T
Review Article Eczema Hay Fever
The methodology for this paper involved an extensive review of recent publications, predominantly those presenting randomized controlled trials, that assess the use of Traditional Chinese Medicine (TCM) in treating allergies. The focus was on the two most popular treatment modalities in TCM, Chinese herbal medicine and acupuncture. Publications detailing the mechanisms by which TCM impacts allergic diseases, as well as literature in Chinese, were also examined.
The analysis of the results showed an increasing trend of using TCM, specifically Chinese herbal medicine, to manage allergic diseases. However, literature evidence was found lacking to conclusively establish its effectiveness. On the other hand, acupuncture showed more definitive evidence of its utility, especially when treating allergic rhinitis and asthma, either as a standalone intervention or alongside conventional western medication. Its effectiveness in treating atopic eczema and urticaria was less clear, nonetheless, it's recommended to be incorporated into the treatment of specific allergic diseases on a personalized basis.
