Processed Food Emulsifiers: Contemplating Gut Training as a Countermeasure?
In a series of recent studies, researchers have delved into the effects of dietary emulsifiers on the gut and its immune system. These substances, commonly found in prepackaged breads, baked goods, low-fat spreads, salad dressings, and other food items, have been found to potentially worsen food allergies and disrupt the activity of the gut microbiota.
The gut microbiome, a vast ecosystem of trillions of microorganisms, plays a crucial role in various health processes. One study published in November 2020 revealed that dietary emulsifiers can indeed disrupt the activity of the gut microbiota.
Among the commonly used dietary emulsifiers are fatty acids extracted from animal fat. However, a new approach to combat the negative effects of these emulsifiers could lie in training the mucosal immune system.
Researchers have discovered that the mucosal immune system can be trained to protect against a specific protein, flagellin, which is a key bacterial protein recognized by the immune system. By training the immune system against flagellin, it is possible to enhance immune tolerance and balance inflammatory responses in the gut, potentially providing benefits in preventing or modulating chronic inflammatory diseases.
Flagellin, which triggers innate immune signaling pathways, can be used to train innate immune cells, enhancing their ability to respond effectively to pathogens while maintaining regulation to avoid excessive inflammation. This concept of "trained immunity" involves metabolic and functional reprogramming of innate immune cells, leading to improved local defense and long-lasting immune memory without reliance on classical adaptive immunity.
In the gut, mucosal immune training against bacterial components such as flagellin can contribute to maintaining immune homeostasis, balancing inflammatory cytokine production, and supporting the development of tolerogenic immune responses. This, in turn, could mitigate the pro-inflammatory effects triggered by emulsifier-induced dysbiosis or microbial translocation.
Therefore, training the mucosal immune system against flagellin harnesses innate immune memory to enhance protective and regulatory immune responses at mucosal sites, potentially preventing or reducing chronic inflammation triggered by dysregulated microbiota or environmental factors like dietary emulsifiers. It could also improve gut barrier function and immune tolerance, reducing the risk or severity of chronic inflammatory diseases linked to microbial and dietary insults.
These insights come from recent advances in understanding trained immunity mechanisms in mucosal tissues and the immunomodulatory role of microbial components such as flagellin in gut health. As research in this area continues, the potential for using microbiota-derived antigens to vaccinate against certain chronic diseases that involve alterations of the gut from food additives becomes increasingly promising.
In conclusion, while dietary emulsifiers have been found to have potential negative effects on gut health and the immune system, the development of strategies to train the mucosal immune system against flagellin offers a promising avenue for combating chronic inflammatory diseases and mitigating the adverse effects of dietary emulsifiers.
