July 31, 2026 - Not all food emulsifiers are bad for the gut microbiome. Gum arabic and arabinogalactan can actually boost the growth of beneficial gut bacteria. Support your family's gut health through life's ups and downs.

May 22, 2024 - “He fed them water containing either CMC, P80 or neither,” says Whelan, “and he found that the mice consuming the emulsifiers had dramatic changes to the diversity of their bacteria. They had a reduction in the number of different types of bacteria in the gut. We don’t think that is a good thing to happen to your gut microbiome.” Greater numbers of pro-inflammatory bacteria were present, too, but this wasn’t all.

March 22, 2021 - Two synthetic emulsifiers in particular, carboxymethylcellulose and polysorbate 80, profoundly impact intestinal microbiota in a manner that promotes gut inflammation and associated disease states.

April 18, 2024 - Findings from the study reported that mice consuming either emulsifier had dramatic changes to the diversity of their bacteria in their gut. They not only had higher numbers of pro-inflammatory bacteria but these mice also seemed to have thinner mucus wall linings. While human digestive systems can’t break down emulsifiers, gut bacteria can.

June 20, 2024 - Common dietary emulsifiers such as lecithin, sucrose fatty acid esters, carboxymethylcellulose, and mono- and diglycerides can promote metabolic disorders and intestinal microbiota dysbiosis in mice.

November 24, 2025 - Dr Megan Rossi realised that there was a gap in the market for breakfast foods that truly deliver on gut health promises ... Have you noticed that the vinaigrette you made by shaking in a jar or whisking vigorously eventually separates with oil on the top and vinegar at the bottom? This is because you created a temporary emulsion between two liquids that can’t naturally blend without that physical force. As a result, they separate over time. Emulsifiers are food additives used to prevent separation in the food industry.

August 25, 2025 - With the rise of ultra-processed foods, the use of food additives has dramatically increased. Among these, emulsifiers have attracted significant attention from researchers due to their potential impact on gut health, metabolism, and inflammation.Emulsifiers are widely used in packaged foods to improve texture, extend shelf life, and enhance flavor.

August 20, 2026 - These are types of food additives called emulsifiers, and they play a major role in creating the texture, consistency, and shelf life of many processed foods. But a growing body of scientific research suggests that these common additives might be doing more than just keeping your salad dressing from separating—they may be significantly affecting the health and balance of your gut microbiome.

April 17, 2025 - Comparing higher to lower consumers of various food additive emulsifiers, small positive associations were observed for cancer (overall cancer, breast and prostate) (11), cardiovascular disease (12) and type 2 diabetes (13). The authors suggest that disruptions in the gut microbiota and increased gut inflammation could be a contributing factor to systemic low grade inflammation that may impact other organs (11).

April 14, 2015 - These dietary compounds promote gut microbiota alteration and gut barrier dysfunction leading to negative metabolic alterations. Check access to the full text by signing in through your organization.Access through your organization

May 19, 2025 - Studies have found that emulsifiers can alter the mix of bacteria in the gut, known as the microbiome or microbiota; damage the lining of the gastrointestinal tract; and trigger inflammation, potentially contributing to problems elsewhere in ...

Early research suggests that some emulsifiers may cause unfavourable changes to the microbiome and disrupt the lining of the bowel wall, potentially leading to inflammation and gut problems.

March 19, 2024 - It stops gut bacteria from reaching the lining and triggering an immune response. In people with IBD, this barrier is deficient, so it’s easier for bacteria to reach the lining and trigger inflammation.

Emulsifiers have been shown to decrease the diversity of the gut microbiome, which increases the risk of obesity and chronic illnesses, like inflammatory bowel disease.

July 7, 2025 - Some emulsifiers can prompt your body to churn out pro-inflammatory molecules, setting off alarm bells throughout your system. Your now disrupted microbiome can contribute to weight gain, insulin resistance, and metabolic syndrome. When your gut barrier breaks down, toxins can slip into your bloodstream, throwing your metabolism into chaos.

January 19, 2026 - Mice studies have shown that polysorbate 80 and sodium carboxymethyl cellulose (CMC)—two common emulsifiers—may change the composition of the gut microbiota and make the bowel wall leaky.

October 27, 2020 - They believe that the heavy mucus is broken down by emulsifiers, allowing the bacteria to get closer to the gut cells and cause inflammation. In addition to inflammation, feeding healthy mice lots of the emulsifiers lead to increased weight ...

They were the focus of a landmark study by Dr. Benoit Chassaing and colleagues that caused quite a stir in the scientific community and the media. The study observed that in mice, some dietary emulsifiers could change the gut microbiota and damage the mucus (epithelial) layer that protects the gut.

June 5, 2026 - Certain emulsifiers have even been linked to health benefits, including lower pro-inflammatory markers, improved gut barrier structure, and increased numbers of beneficial bacteria.
