US EditionUltra-Processed Foods and Food Additives in Gut Health and Disease
- A 2025 UK study reported that close to half of Crohn's patients who eliminated emulsifiers experienced notable symptom improvement and a reduction in gut inflammation.
- This finding builds on concerns that emulsifiers disrupt the intestinal mucus layer, triggering chronic inflammation linked to autoimmune diseases and cancer.
- Separately, researchers, including Dr. Renee Dufault, focus on how ultra-processed foods contribute to prenatal heavy metal exposure affecting metallothionein gene expression and child neurodevelopment.
- Experts also debate the classification of ultra-processed foods, with new definitions emerging that consider additive processing and nutritional content, while some industry groups criticize these scales for consumer confusion.
- These studies and debates suggest the need for nuanced assessment of food additives and processing to improve public health outcomes related to gut inflammation, cancer risk, and developmental disorders.

Ultra-processed foods linked to prenatal heavy metal exposure and child brain development
In a recent study published in World Journal of Experimental Medicine, scientist Dr. Renee Dufault at the Food Ingredient and Health Research Institute provides a protocol for determining the role ultra-processed foods play in prenatal heavy metal exposures and changes in the expression of the zinc dependent MT-1 (metallothionein) gene that impacts child neurodevelopment.

Ultra-processed foods and food additives in gut health and disease
Ultra-processed foods (UPFs) and food additives have become ubiquitous components of the modern human diet. There is increasing evidence of an association between diets rich in UPFs and gut disease, including inflammatory bowel disease, colorectal cancer and irritable bowel syndrome. Food additives are added to many UPFs and have themselves been shown to affect gut health. For example, evidence shows that some emulsifiers, sweeteners, colours, a…

New research reveals alarming links between common food emulsifiers and serious health risks, including Crohn’s disease and cancer. Discover what these additives really do to your gut and how to protect yourself with simple dietary changes.
Dangerous Ingredients: EMULSIFIERS In Food Linked To Crohn’s Disease And Cancer
A 2025 U.K. study (ADDapt trial) found that nearly 50 percent of Crohn’s patients avoiding emulsifiers saw significant symptom relief, compared to only 31 percent in the emulsifier-consuming group. Gut inflammation dropped by over 50 percent in the emulsifier-free group.
