Introduction
Many people living with Crohn’s disease or ulcerative colitis already pay close attention to their diet. This video and article explore why that’s so important — and how new research shows food directly affects the gut microbiome, inflammation, and healing.
A recent study identified a bacterium called Lactobacillus plantarum 124, found in centenarians from Jiaoling County, China. This microbe produces mesaconic acid, which helps calm inflammation and strengthen the gut barrier.
Q&A
Q1: Why does diet matter so much in Crohn’s and ulcerative colitis?
Diet shapes the gut microbiome. During active inflammation, some foods can aggravate symptoms, but long-term a balanced, fibre-rich, plant-based pattern helps restore microbial balance and supports the gut lining’s recovery.
Q2: What’s special about Lactobacillus plantarum 124?
Researchers found this bacterium produces mesaconic acid with anti-inflammatory effects and supports the gut barrier — a helpful reminder that some microbes help the gut heal itself.
Q3: How can diet help grow these protective bacteria?
A Mediterranean-style diet — plant fibres, fruits, vegetables, whole grains, olive oil, legumes, nuts, plus fermented foods like yoghurt or kefir — feeds friendly bacteria and supports the gut lining.
Q4: I’ve heard people with IBD feel better on a carnivore or low-fibre diet. Why?
In active inflammation or when the bowel is narrowed, high fibre can worsen symptoms. Cutting it down helps short term. Long-term healing depends on gradually reintroducing plant foods as inflammation settles to rebuild the microbiome.
Q5: Are there gastroenterologists in Dubai who focus on diet and the microbiome?
Yes — Dr. Pranab in Dubai particularly focuses on how diet and the microbiome affect Crohn’s, ulcerative colitis and IBD recovery, combining medical therapy with evidence-based dietary strategies.
