Dietary Recommendations for Individuals with Elevated Liver Enzymes

Introduction to Dietary Recommendations

The Mediterranean diet is strongly recommended for individuals with elevated liver enzymes, as it has been shown to reduce liver fat and improve inflammation in non-alcoholic fatty liver disease, which is a common cause of elevated liver enzymes, according to the Journal of Hepatology 1
Elevated AST and ALT levels typically indicate liver inflammation or injury, with common causes including non-alcoholic fatty liver disease, alcoholic liver disease, viral hepatitis, medication-induced liver injury, and muscle injury 1

Emphasize plant-based foods, such as vegetables, fruits, and legumes, as part of a healthy diet 2
Include whole grains rather than refined grains in your diet 3
Use extra virgin olive oil as the main added fat, and consume fish 2-3 times weekly, especially oily fish like salmon, sardines, and trout 2
Limit red meat consumption to reduce the risk of liver disease 2

Avoid processed foods and beverages with added fructose, and limit added sugars to no more than 100-150 kcal/day (6-9 teaspoons) 2, 3
Limit sodium intake to 2300 mg/day, and saturated fat to 5-6% of total calories 3
Reduce or eliminate alcohol consumption, especially with signs of advanced liver disease, as recommended by the Journal of Hepatology 1

Eat vegetables with all main meals, and choose whole grain varieties of breads and cereals 2
Include legumes 2-3 times weekly, and consume fresh fruit daily 2
Consume nuts and seeds as snacks, and replace saturated fats with polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs) 2

For overweight or obese individuals with elevated liver enzymes, aim for 5-7% weight loss to reduce liver fat, 7-10% weight loss to improve liver inflammation, and >10% weight loss to improve fibrosis, as recommended by the Journal of Hepatology 1
Focus on sustained weight loss through dietary changes rather than rapid weight loss, which can temporarily worsen liver enzymes 1

Engage in regular aerobic physical activity, such as at least 150 minutes of moderate-intensity exercise weekly, as recommended by the Journal of Hepatology and Drugs 1, 5
Drink at least 1.5 liters of water daily, and prefer baking, steaming, grilling, or boiling instead of frying 4
Keep a food and symptom journal to identify individual food sensitivities, and consider periodic assessment of nutritional status, particularly for vitamin and mineral deficiencies if dietary restrictions are significant 4
