New Research and Dietary Approaches for Gut Health in Asia
Previous studies estimated that the incidence of IBD in Asia is generally less than 5 per 100,000 people, with specific rates ranging from 0.5 to 3 per 100,000 across various countries. Over the years, significant yet varying increases have been noted across the region, particularly in East Asia, where urbanization and other factors have driven a rising incidence of IBD. A recent study, “Evolving Trends and Burden of Inflammatory Bowel Disease in Asia”, projects a continued rise in the IBD burden over the next 25 years, highlighting the need for targeted medical policies and strategies to address this rising public health issue.
Chinese researchers advance IBD diagnosis
Researchers at the Chinese University of Hong Kong’s Faculty of Medicine (CU Medicine) have made a significant advancement in diagnosing gastrointestinal (GI) disorders, particularly inflammatory bowel disease (IBD). Their discovery could transform the way these conditions are diagnosed and treated, moving away from invasive procedures like endoscopies to a more accessible, non-invasive test.
IBD, which includes conditions like ulcerative colitis and Crohn’s disease, is a growing health concern, especially in Asia. The symptoms, including recurrent abdominal pain and diarrhea, are often mistaken for irritable bowel syndrome (IBS), a common functional disorder. This overlap complicates the diagnosis and can lead to delayed treatment, which in severe cases may require drastic measures like surgery. Currently, there is no reliable, non-invasive test to distinguish between IBS and IBD, with colonoscopies and imaging scans being the standard, but often inconvenient, methods of diagnosis.
Ulcerative colitis and Crohn’s disease, forms of IBD, cause symptoms like diarrhea, rectal bleeding, abdominal pain, fatigue, and weight loss, ranging from mild to potentially life-threatening severity, according to Mayo Clinic.
CU Medicine’s researchers analyzed nearly 6,000 stool samples from patients across 11 countries, representing diverse ethnicities. Their goal was to identify unique microbial signatures that could differentiate IBD from other GI disorders. Based on the findings, ten bacterial species linked to ulcerative colitis (UC) and nine associated with Crohn’s disease. These bacteria play a crucial role in the development of IBD and provide a basis for diagnostic innovation.
By combining their findings with advanced machine learning techniques, the team developed a diagnostic model that can identify IBD with remarkable accuracy. The model showed significant sensitivity and specificity of nearly 90%, meaning it could reliably detect the disease. But the real breakthrough came when these microbial markers were integrated into a multiplex digital droplet PCR (ddPCR) test, making the process faster and more effective.
This novel approach offers a huge advantage over traditional methods. Not only is it non-invasive, but it also provides quicker results, which could lead to faster diagnoses and more timely treatment. The new diagnostic tool is set to be ready for clinical use by 2027, and its potential could go beyond diagnosis—it may also help in monitoring disease progression, predicting drug responses, and tailoring treatments for individual patients.
The team’s innovation has already earned recognition, including a Silver Medal at the Geneva International Exhibition of Inventions in 2024. With the rising incidence of IBD in Asia, particularly in China where the number of patients is expected to exceed 1.5 million by 2025, this diagnostic breakthrough comes at a critical time. It could ease the burden on healthcare systems and improve patient outcomes by making IBD diagnosis and management more efficient.
Healing through nutrition
The Massachusetts-based UMass Chan medical school’s Center for Applied Nutrition offers a solution to support recovery and healing through nutrition. The Anti-Inflammatory Diet for IBD (IBD-AID) , which is designed to restore gut bacteria balance, reduce inflammation, and support remission in IBD patients through specific dietary principles. It includes four daily components:
Probiotics: Foods like yogurt, kefir, kimchi, raw honey, miso, sauerkraut, pickles, aged cheeses, etc., to introduce beneficial bacteria.
Prebiotics: Soluble fiber from foods like steel-cut oats, banana, garlic, onion, artuchokes, asparagus, leeks, all vegetables, ground flax seeds, etc., to nourish good bacteria and improve gut health.
Avoidance: Eliminate inflammatory foods such as refined sugars, wheat, lactose, corn, trans fats, emulsifiers, and processed or fast foods to help the gut recover.
Good Nutrition: Focus on fruits, vegetables (prepared to suit tolerance), lean proteins, and healthy fats from sources like nuts, avocado, and olive oil, while limiting saturated fats to <5g/serving (meats, dairy, etc.)
Together, these elements aim to repair the gut, decrease inflammation, and support immune system balance. Moderate consumption of coffee, tea, and wine is allowed, but beer and refined sugars should be avoided.
