# Nutrition and diets in autoimmune hepatitis
Dietary choices play a supportive role in the treatment and well-being of people with autoimmune hepatitis. This tab describes which diets and nutritional patterns are mentioned in research or practice, and what is known about them.
Mediterranean dietary pattern
ResearchediPositive results in clinical studies, not yet standard treatment
The Mediterranean dietary pattern consists of many vegetables, fruits, whole grains, legumes, nuts, olive oil and moderate amounts of fish and poultry, with limited red meat. This pattern is known for its anti-inflammatory properties.
Research into nutrition and chronic diseases (2026) has provided indications that certain nutrients and patterns are associated with lower risks of chronic conditions, including autoimmune diseases. In autoimmune hepatitis, anti-inflammation plays a role, which makes the Mediterranean pattern theoretically appealing. However, direct studies of this pattern in autoimmune hepatitis are limited.
Benefits seen in broader autoimmune diseases are improved inflammatory markers and better quality of life. Risks are not known, provided it is well balanced.
Protein-rich nutrition
ResearchediPositive results in clinical studies, not yet standard treatment
A dietary pattern with adequate protein (from fish, poultry, eggs, legumes and dairy products) supports muscle strength and liver recovery processes.
In advanced autoimmune hepatitis with possible cirrhosis, adequate protein intake may be important to prevent muscle wasting and support liver metabolism. However, in patients with hepatic encephalopathy (confusion due to accumulation of substances), protein restriction may be needed, which must be determined on a case-by-case basis. Studies on optimal protein intake specifically for autoimmune hepatitis are scarce.
Research into nutritional deficiencies and quality of life in autoimmune liver diseases (2026) suggests that nutritional status is related to outcomes, but concrete nutritional interventions are not yet well standardized.
Risk: high animal protein can raise inflammatory markers in some people; a dietitian can find balance.
Nutrition with minimal additives and refined substances
ResearchediPositive results in clinical studies, not yet standard treatment
Nutrition with plenty of fresh, unprocessed food (vegetables, fruits, nuts, whole grains) and little ultra-processed products, artificial dyes and preservatives.
The immune system in autoimmune diseases reacts to substances the body experiences as foreign. Some additives can trigger a reaction, but evidence specific to autoimmune hepatitis is lacking. However, research into autoimmune diseases in general suggests that dietary patterns with many processed substances are associated with elevated inflammatory markers.
Direct harm from additives to the treatment of autoimmune hepatitis has not been demonstrated, but a clean, simple dietary pattern is consistent with anti-inflammation in general.
Limiting alcohol
ProveniIncluded in official guidelines, or approved by EMA or FDA
Alcohol should be completely avoided or reduced to a minimum.
The liver metabolizes alcohol, and in autoimmune hepatitis liver function is already impaired. Alcohol worsens inflammation, promotes scarring (fibrosis) and can disrupt medication breakdown. This is not experimental: an alcohol-free or very moderate diet (according to national guidelines usually 0–1 standard glass per week) is a basic rule.
**Risk:** alcohol significantly accelerates liver damage and undermines all medication treatment.
Sodium restriction
ResearchediPositive results in clinical studies, not yet standard treatment
Nutrition with limited amount of salt (sodium), important especially in cirrhosis with fluid accumulation (ascites) or high blood pressure in the portal vein.
In advanced autoimmune hepatitis with cirrhosis, doctors sometimes use sodium restriction to prevent fluid retention. Research into the precise dietary contribution to this is part of broader body fluid management. Sodium restriction alone does not resolve fluid accumulation, but can support treatment.
Risks are minimal with proper guidance, but overly strict dietary advice can lead to monotonous eating and nutritional deficiencies.
Micronutrients and supplements
ResearchediPositive results in clinical studies, not yet standard treatment
Vitamins (especially D, E, B-vitamins) and minerals (zinc, selenium) can become deficient in liver disease, because the damaged liver does not store or metabolize these substances properly.
Research on nutritional status in autoimmune liver diseases (2026) shows that deficiencies occur and are associated with poorer recovery. However, supplementation is strongly dependent on blood values and individual circumstances. In fact: obtaining a variety of vitamins and minerals through food (plenty of vegetables, fruit, nuts) is less risky than high-dose supplements.
**Note:** many supplements are broken down by the liver. Some (for example, certain herbal teas and extract supplements) can cause liver inflammation, even without a prescription. This is increasingly recognized in 2026 research into medication-related liver injury.
Discuss all supplements with your healthcare provider; self-medication is risky.
Fasting and periodic eating patterns
ExperimentaliOngoing in study setting, outcome still unknown
Intermittent fasting (periods of not eating alternated with eating) or other periodic fasting is being investigated in some studies for autoimmune effects.
Theoretically, brief fasting can lower inflammatory markers, but research specific to autoimmune hepatitis does not exist. Moreover: with liver disease, irregular eating can lead to nutritional deficiencies, and fasting can negatively affect liver function.
**Risk:** fasting without guidance can cause deterioration in liver function and muscle breakdown.
Conclusion
Dietary choices in autoimmune hepatitis are individualized. They serve to support medication treatment, not to replace it. The main guidelines (no alcohol, adequate protein, fresh food, avoidance of risky supplements) are the same for everyone; but dosage, timing, and individual adjustments (for example, in cirrhosis with encephalopathy) depend on your disease stage, blood values, and medications.
Work together with a dietitian and your hepatologist. They can use blood tests to identify deficiencies and tailor your diet precisely.
