Explore how ultra-processed foods and additives like polysorbate 80 impact Crohn’s disease and gut health according to University of Liverpool research.
The gut isn't just a digestive tube—it is the primary frontier of your immune system. When this frontier is compromised, the result isn't just a stomach ache; it can be a lifelong struggle with chronic inflammation.
The biological link between ultra-processed foods (UPFs) and Crohn’s disease, specifically focusing on how additives like emulsifiers (CMC, polysorbate 80), thickeners (carrageenan), and stabilizers (maltodextrin) damage the gut barrier, trigger chronic immune responses due to bacterial penetration, and cause microbiome dysbiosis through fiber deficiency and the production of pro-inflammatory microbes.
Research from the University of Liverpool suggests that ultra-processed foods, common in the Western diet, contain additives that can compromise the gut's immune defenses. These substances, often found in snacks and dressings, may turn a peaceful coexistence with bacteria into chronic inflammation. By breaking down the body's vital intestinal barriers, these food components are linked to the rising global rates of Crohn’s disease.
Carboxymethylcellulose and polysorbate 80 are common food additives used to maintain texture in products like ice cream, almond milk, and salad dressings. While often viewed as inert, these substances can fundamentally change how the body interacts with the gut microbiome. Evidence indicates they may act as invisible saboteurs that weaken the intestinal tissue, potentially triggering long-term inflammatory responses in the digestive system.
The Western diet is characterized as a high-fat, high-sugar, and low-fiber landscape that has become a global standard over the last fifty years. This dietary pattern introduces various ultra-processed ingredients that affect the trillions of microbes living in the human gut. Instead of viewing Crohn’s disease solely as a result of genetics, researchers are now looking at how this specific diet compromises the primary frontier of the immune system.

Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!
@ladyInfinity
I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.
@jayallen
The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.
@Raguipa
What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.
@colonyofcreatorsNGO
I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.
@BeFreed user
It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.
@austinakon
I love this app. Used it for several days and I cannot stop listening. Such a great way to start.
@jcrules328
I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.
@DanielCZ
I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.
@BeFreed user
I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.
@Brad
I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!
@BeFreed user
The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.
@jayallen
BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.
@BeFreed user
At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!
@matteo77
BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
