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.
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.

Systematic Review Acupuncture Moxibustion Ulcerative Colitis
Methodology: This evaluative study used an extensive and systematic methods to search data from seven different databases. The selected data were further refined by using different screening and evaluation frameworks like AMSTAR-2, PRISMA, ROBIS, and GRADE systems. These were used to determine the methodological quality, reporting quality, risk of bias, and the quality of evidence in the selected studies.
Discussion of results: After critical evaluation, the study found ten relevant reviews and analyses that showed potential for acupuncture and moxibustion therapies being effective in ulcerative colitis treatment. However, many the identified studies were reported to have several problems in their overall design and quality of outcomes. The researchers therefore stress caution when interpreting these results due to the lack of high-quality evidence in the existing studies.

Meta-Analysis Acupuncture Moxibustion Ulcerative Colitis
Methodology: The researchers carried out a systematic review and network meta-analysis of clinical efficacy of various acupuncture therapies for ulcerative colitis patients. They accomplished this by sourcing for Clinical Randomized Controlled trial articles from databases such as PubMed, Embase, Cochrane Library, and other data knowledge service platforms, all of which were independently reviewed by two researchers. Several quality assessments were made through Review Manager software, and the meta-analysis was conducted with Stata 16 software. Interventions examined in the analysis included acupuncture, moxibustion, acupoint catgut embedding, and combinations of these therapies with Western medicine.
Discussion of results: 52 articles encompassing 3924 patients participated in randomized control trials. The investigation revealed a range of interventions, including different acupuncture therapies and combinations of these therapies with Western medicine. Namely, moxibustion, either on its own or combined with Western medicine, consistently surfaced as top-ranked for overall effectiveness and specific outcomes. Moreover, moxibustion displayed impressive performance in reducing adverse reactions and recurrence rates. Thus, various acupuncture therapies were confirmed as safe and effective for the treatment of ulcerative colitis, with moxibustion emerging as the most effective.
A combined Mediterranean, low-FODMAP diet along with partial enteral nutrition has shown promise in reducing ulcerative colitis activity and improving patients' quality of life.

Randomised Controlled Trial Low FODMAP Ulcerative Colitis
In the study, fifty patients with active, mild to moderate ulcerative colitis were randomly allotted one of two diets: a combined Mediterranean, low-FODMAP diet supplemented with partial enteral nutrition, or a standard diet. These diets were implemented for a duration of 6 weeks. Before and after the intervention, various indicators of the patients' conditions were measured. These variables included a disease activity index, the patients' quality of life, and concentrations of various inflammatory and oxidative stress factors in the blood. All of these were measured using tested and trustworthy questionnaires, in conjunction with blood sampling.
The combined diet was found to result in significantly decreased disease activity index values, compared to both the control diet and the baseline data. Simultaneously, patients on the combined diet reported greater enhancements in their quality of life, compared to both the control group and the initial data. Lastly, the serum level of a protein called "high sensitive C-reactive protein," known to be a general marker of inflammation within the body, was found to be reduced in the combined diet group. However, changes in the serum total antioxidant capacity were found to be statistically insignificant across both groups.
A polysaccharide from Tremella aurantialba improves ulcerative colitis symptoms by targeting epithelial cell ferroptosis and modulating the gut microbiota.

Animal Study Gut Microbiota Intestinal Barrier Snow Fungus
The methodology used in this research involved isolating TA 2-1, a specific polysaccharide from Tremella Aurantialba, and studying its effects on ulcerative colitis. This was done by introducing it to Caco-2 cells that were undergoing ferroptosis and assessing its impact on cell viability. The influence of TA 2-1 was also examined in mice with artificially induced ulcerative colitis, verifying its ameliorating effects in an in-vivo context. The structure of TA 2-1 and its components were analysed and the polysaccharide's interaction with gut microbiota was explored to understand how it might modulate symptoms or prevent cell death.
The results of this study showed that TA 2-1 does not only decrease the rate of cell death in epithelial cells undergoing ferroptosis, but it also repairs the intestinal barrier by upregulating specific proteins such as claudin-1 and zonula occludens-1. TA 2-1 was also found to suppress lipid peroxidation, thus inhibiting ferroptosis. Further investigation revealed that TA 2-1 may alleviate ulcerative colitis by influencing the composition or metabolites of gut microbiota. This research offers promising insight into the potential of TA 2-1 in treating ulcerative colitis.
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.
2024 Nutrition Journal Association of maternal ultra-processed food consumption during pregnancy with atopic dermatitis in infancy: Korean Mothers and Children’s Environmental Health (MOCEH) study Jang W, Kim M, Ha E, Kim H
Eczema Ultra-Processed Foods
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.
