Gut-Liver Connection: Why Your Diet Matters for Both Organs

The gut has become the centre of wellness discussions — and for good reason. Linked to the brain and immune system through the gut-brain and gut-immunity axes, it influences key functions such as digestion, nutrient absorption, and microbiome balance. But experts say the gut’s impact extends even further — directly to the liver.

Dr Sukhvinder Singh Saggu, Director of Minimal Access, GI & Bariatric Surgery at CK Birla Hospital, Delhi, told HT Lifestyle that the liver’s health is closely tied to gut function. “The gut-liver axis connects your digestive system and liver through blood flow and immune signalling. What you eat impacts gut bacteria, which in turn influences liver health. Inflammation in the gut can travel to the liver, worsening liver diseases like hepatitis,” he explained.

How diet affects both gut and liver

Your diet plays a decisive role in this two-way relationship. Foods high in processed ingredients, sugar, saturated fats, and alcohol disrupt the gut microbiome — a condition called dysbiosis. “This imbalance weakens the intestinal lining, allowing toxins, bacteria, and inflammatory substances to leak into the bloodstream and reach the liver,” Dr Saggu said.

Such “leaky gut” damage can inflame the liver and accelerate fibrosis (scarring), posing added risks for patients with hepatitis B or C.

Foods that support gut-liver health

To protect both organs, Dr Saggu recommends a diet rich in fibre, antioxidants, and healthy fats, which restore gut balance and ease liver stress. His suggestions include:

• Fruits, vegetables, whole grains, legumes, nuts, seeds, and omega-3-rich foods like fatty fish

• Probiotics such as yoghurt, kefir, kimchi, and sauerkraut

• Prebiotics like garlic, onions, and bananas

“These foods help block harmful substances from reaching the liver and lower systemic inflammation,” he noted.

Why it matters for hepatitis patients

Since hepatitis involves inflammation of the liver, a gut-friendly diet is especially beneficial. According to Dr Saggu, it can strengthen immune function, improve treatment response, and slow the progression of liver damage.
