The liver is a vital organ responsible for detoxification, metabolism, and nutrient storage. Fatty liver disease, characterized by an excess of fat in the liver, can impair these functions and lead to serious health complications. While fatty liver is a common condition among individuals who abuse alcohol, are obese, and have a sedentary lifestyle, it is also one of the main causes of liver failure. Fortunately, dietary changes can play a significant role in managing and treating fatty liver disease, and more general liver disfunction.
Understanding Fatty Liver Disease
Fatty liver disease is characterized by an excess of fat in the liver. Normally, the liver functions to remove toxins and produce bile and digestive proteins. Fatty liver disease damages the liver and prevents it from functioning properly. There are two main types:
- Alcohol-related fatty liver disease (AFLD): Caused by excessive alcohol consumption, which directly harms the liver.
- Non-alcoholic fatty liver disease (NAFLD): Diagnosed in individuals who are obese and have a sedentary lifestyle.
One of the primary ways to address fatty liver disease is through scientific dietary modifications. A well-planned diet should meet the following criteria:
- High in fruits and vegetables.
- Rich in fiber, including legumes and whole grains.
- Low in sugar and unhealthy fats.
- Low in sodium.
- Free of alcoholic beverages.
Foods to Embrace for a Healthier Liver
Incorporating specific foods into your diet can significantly support liver health and help manage fatty liver disease.
Coffee: A Liver-Enzyme Lowering Elixir
Studies suggest that regular coffee consumption can reduce liver damage in individuals with fatty liver disease. Caffeine has been shown to help reduce abnormal liver enzyme levels in those at risk for liver diseases. It’s even been recommended that people with fatty liver disease should drink three or more cups of coffee a day. If you don’t have health issues with your liver, you may not need to drink that much - but know that your cup of joe may help improve your liver function.

Important Note: It should be black coffee without added sugar or creamer.
Leafy Greens: Nature's Shield Against Fat Accumulation
Vegetables, particularly leafy greens like spinach and kale, and broccoli, help prevent fat accumulation in the liver. These greens are also beneficial for weight loss. They also have glutathione, which Dr. Lindenmeyer adds is a healthy antioxidant that can be helpful for your liver as well.
Tofu: A Protein-Packed Fat Reducer
The protein content in tofu helps reduce fat accumulation in the liver. Tofu is also low in fat and high in protein, making it an excellent addition to a liver-friendly diet.
Fatty Fish: Omega-3 Powerhouse
Fatty fish, such as salmon, sardines, tuna, and mackerel, are rich in omega-3 fatty acids, which improve liver fat levels. These supplements may help by reducing inflammation, enhancing insulin sensitivity, lowering levels of triglycerides, lowering liver fat, optimizing HDL (good) cholesterol and liver enzymes.
Oatmeal: Sustained Energy and Weight Management
Carbohydrates from whole grains like oatmeal provide energy and fiber. The fiber content helps you feel full longer and aids in weight management. In addition, a study from 2017 suggests that as oats and oatmeal are high in soluble fibers called beta-glucans, they may also help prevent obesity and inflammation.

Walnuts: Nuts for Improved Liver Function
Nuts, especially walnuts, are rich in omega-3 fatty acids. Studies have shown that regular walnut consumption improves liver function test results in people with fatty liver disease. In a 2021 study, participants were provided 28 grams (1 ounce) of walnuts every day as part of a Mediterranean diet. People who ate walnuts at least five or six times a week had significantly greater liver fat loss than those who ate walnuts less often. This fat loss was associated with overall anti-inflammatory and metabolic health benefits.
Avocado: Healthy Fats and Liver Protection
Avocado boasts healthy fats and compounds that slow down liver damage. It is also rich in fiber, which supports weight management.
Milk and Low-Fat Dairy: Whey Protein Benefits
Milk, particularly low-fat milk, contains whey protein, which can protect the liver from damage.
Sunflower Seeds: Antioxidant Support
Sunflower seeds are rich in vitamin E, an antioxidant that can protect the liver from damage.
Olive Oil: Weight Management and Enzyme Reduction
Olive oil, especially extra virgin olive oil (EVOO), is a healthy oil rich in omega-3 fatty acids. It helps reduce liver enzyme levels, manage weight, and protect the liver from damage by decreasing inflammation, oxidative stress, endoplasmic reticulum stress, mitochondrial dysfunction, and insulin resistance.

Garlic: Flavorful Weight and Fat Reduction
Garlic enhances the flavor of dishes and helps reduce body weight and fat in individuals with fatty liver disease.
Green Tea: Fat Storage Reduction and Liver Function Improvement
Green tea can reduce fat storage in the liver and improve liver function. It also offers other health benefits, such as lowering cholesterol and promoting better sleep.
Other foods that can help with liver function
- Olives and olive oil Whether you like to eat olives straight out of the jar or olive oil with a squeeze of lemon is your preferred salad dressing, this savory fruit can help boost your liver’s health. Mainly, olives are rich in vitamin E and antioxidants - two things your liver loves.
- Berries Including antioxidants in your diet is something that your liver (and other parts of your body) will thank you for. While more research is still necessary, a series of animal studies have suggested that cranberries and blueberries could improve liver health, too.
Foods to Avoid for Liver Health
Certain foods can exacerbate fatty liver disease and should be limited or avoided.
Alcohol
Alcohol is a primary cause of fatty liver disease and other liver ailments.
Sugary Foods
Foods high in sugar, such as candies, cookies, sodas, and fruit juices, raise blood sugar levels and lead to fat accumulation in the liver.
Fried and Greasy Foods
These foods contribute to weight gain and increased fat accumulation in the liver.
Excessive Salt
Excessive salt intake can cause water retention, exacerbating liver issues.
White Bread, Rice, and Pasta
These refined carbohydrates can increase blood sugar levels more than whole grains.
Red Meat
Limit red meat, such as beef and processed meats, due to their high saturated fat content.
Lifestyle Changes for Enhanced Liver Health
In addition to dietary changes, adopting a healthy lifestyle can significantly improve liver health.
Maintaining an Exercise Routine
Regular exercise, combined with a proper diet, aids in weight loss and liver disease management. Aim for at least 30 minutes of aerobic exercise each day.
Reducing Cholesterol
Monitor saturated fats and sugars to help control cholesterol and triglyceride levels. If diet and exercise are insufficient, consult your doctor about medication options.
Managing Diabetes
Diabetes and fatty liver disease often occur together. A proper diet and exercise can help manage both conditions. If your blood sugar remains high, inform your doctor for potential medication.
Additional Considerations for Liver Health
Staying Hydrated
Generous water intake helps maintain a dilute urine and decreases the risk of kidney stones. Aim for 2-3 quarts of urine output daily. Consider fruit-infused water or coconut water to elevate hydration.
Limiting Caffeine
Limit caffeine intake to less than 200 to 250 mg daily, as it can slow the degradation of cyclic AMP (cAMP), which promotes cyst growth in polycystic kidneys.
Monitoring Potassium and Phosphorus
While potassium is essential, avoid potassium supplements without consulting your doctor. When kidney function declines, the body struggles to balance phosphorus.
Vitamin Intake
If you feel you need extra vitamins, a one-a-day, generic brand of vitamin is sufficient. Consult your doctor before taking extra vitamins of any kind.
Salt Intake
Excessive amounts of salt should be avoided and lowering dietary salt may help in blood pressure control. Choose fresh or frozen vegetables instead of canned vegetables. Avoid canned soups and frozen dinners that are high in sodium.
Protein Intake
When you have lost a significant amount of kidney function, a lower protein diet may be ordered by your doctor. Recommended: 0.8 g/Kg of body weight.
Addressing Malnutrition in Liver Disease
Liver disease can lead to poor appetite and difficulty in absorbing nutrients. To combat malnutrition:
- Eat small, frequent meals throughout the day.
- Ensure each meal contains protein.
- Eat a protein-rich snack before bed to maintain blood sugar levels overnight.
- Consider nutritional supplements if appetite is poor.
Understanding Polycystic Liver Disease (PLD)
Polycystic liver disease (PLD) is a rare genetic condition characterized by the development of cysts throughout the liver. While most people with PLD do not experience symptoms, a well-balanced diet will help protect liver function.
Dietary Recommendations for PLD
- Include plenty of fruits and vegetables, fiber-rich whole grains, low-fat dairy products, and lean sources of protein.
- Avoid processed foods, alcohol, and raw shellfish.
Debunking Liver Health Myths
- Myth: The liver requires special diets or cleanses to detoxify.
- Fact: The liver naturally eliminates toxins.
- Myth: Alcohol is the only cause of liver damage.
