7 Foods To Avoid With Fatty Liver Disease
November 14, 2025
Highlights:
Sugary drinks, fried foods, refined carbs, salty snacks, and alcohol are top offenders for worsening fatty liver disease. The Mediterranean diet, when combined with C15:0, shows even greater benefits for reducing liver fat and supporting metabolic health. Supporting your liver at the cellular level with nutrients like C15:0 may help protect against inflammation, fibrosis, and long-term damage.
Your liver is one of the hardest-working organs in your body. It filters toxins, processes nutrients, and helps keep your metabolism humming. Fatty liver disease can develop when fat begins to build up in liver cells. While genetics and lifestyle play roles, diet is one of the most important factors in protecting (or harming) your liver.
If you’ve been diagnosed with fatty liver disease, the good news is that making smart dietary choices can make a real difference. Just as some foods support liver repair, others can worsen it.
Let’s take a closer look at seven foods and drinks that research shows you should avoid with fatty liver disease, and a research-backed supplement that can also support liver function.
1. Sugary Drinks
Those caramel macchiatos may hit the spot and satisfy your sweet tooth, but they aren’t doing your liver any favors. Flavored coffees, sodas, and energy drinks contain high amounts of fructose, which is processed primarily by the liver.
Unlike glucose, which triggers the release of insulin and is delivered to virtually every cell in the body, fructose bypasses the insulin trigger and gets shuttled to the liver for processing. When consumed in excessive amounts, fructose is stored in liver cells as fat.
Research shows that diets high in fructose are strongly linked to the development of non-alcoholic fatty liver disease, or NAFLD. This is probably why fructose-filled beverages are considered one of the biggest dietary culprits.
Swap with: Water with lemon, sparkling water, black coffee, or herbal tea. If you need an extra kick of sweetness, try a splash of fruit juice diluted with sparkling water.
2. Fried Foods
Who doesn’t love a crispy French fry or a beer-battered filet? Your liver, that’s who. Frying food typically involves the use of oils high in unhealthy fats, which can contribute to insulin resistance and increased fat accumulation in the liver.
One study pointed out that regular consumption of fried foods led to an increase in inflammation in the liver, which can contribute to the progression from NAFLD to non-alcoholic steatohepatitis, or NASH. In people who have NASH, liver damage is more extensive and harder to reverse. People with NASH also have a higher risk of cirrhosis and fibrosis.
Swap with: Air-fried or oven-baked versions of your favorite foods, and swap your cooking oil for olive oil.
3. Refined Carbohydrates
If white bread, pasta, and pastries are some of your favorite things, you’re not alone. Consumption of refined carbohydrates is on the rise, and our livers are paying the price.
Refined carbs have been stripped of their nutrients and fiber, causing them to digest quickly and spike blood sugar and insulin levels. When insulin levels are elevated, it prompts the liver to store fat. These foods are considered to have a high glycemic index. High-glycemic index diets are associated with poor liver fat scores.
Swap with: Whole grains like oats, quinoa, and brown rice. Fiber slows down digestion and helps regulate blood sugar levels.
4. Red and Processed Meats
Bacon, sausage, pepperoni, hot dogs, and fatty cuts of beef are hard on your arteries and tough on your liver. These meats are high in unhealthy fats and often contain preservatives and sodium that worsen inflammation.
Processed meats, in particular, have been linked to a higher risk of metabolic syndrome, which often accompanies fatty liver disease. Some studies suggest that diets high in red and processed meats may contribute to increased oxidative stress in liver tissue.
Swap with: Lean cuts of meat like chicken and fish, and plant-based sources such as lentils, legumes, and beans.
5. Alcohol
It may seem obvious, but alcohol deserves a spot on this list. Alcohol is directly toxic to liver cells, and heavy drinking is the leading cause of alcoholic fatty liver disease (AFLD). Even moderate amounts of alcohol can worsen NAFLD, particularly when combined with other risk factors like obesity, diabetes, or high cholesterol.
Your liver metabolizes alcohol into acetaldehyde, a compound that causes oxidative stress and inflammation. Over time, this process damages liver tissue and can lead to cirrhosis.
Swap with: Sparkling water with lime, kombucha, or a mocktail using fresh herbs and citrus.
6. Salty Foods
Too much salt can negatively impact your blood pressure and your liver health. Diets high in sodium have been linked to worsening liver fibrosis and inflammation. Salt can also contribute to water retention and swelling, which may complicate liver disease symptoms.
Processed foods like canned soups, frozen meals, deli meats, and packaged snacks often hide large amounts of sodium. Even if you don’t add salt at the table, your daily intake can easily exceed recommended levels.
Swap with: Fresh or minimally processed foods seasoned with herbs, spices, garlic, or citrus. When buying packaged items, check labels and choose low-sodium options whenever possible.
7. Processed Snack Foods
Chips, cookies, pastries, and packaged snack cakes often combine refined carbs, added sugars, and hydrogenated oils, a triple threat for liver health. These foods contribute to fat buildup and increase systemic inflammation, which can worsen liver damage.
Because processed snacks are typically low in fiber and nutrients, they also crowd out healthier options in your diet. That means fewer protective foods that contain liver-healthy vitamins and minerals, like fruits and vegetables.
Swap with: Nuts, seeds, veggie sticks with hummus, or homemade popcorn (lightly seasoned).
Why Avoiding These Foods Matters
Your liver is remarkably resilient, but some damage, like scarring, is irreversible. Eating foods high in added sugars, saturated fats, and processed ingredients drives fat buildup in liver cells and chronic inflammation. Left unchecked, this can lead to NASH, fibrosis, cirrhosis, and even liver cancer.
On the flip side, dietary improvements have been shown to reduce liver fat, improve liver enzyme levels, and even reverse early-stage disease. One of the most promising diets for fatty liver disease is the Mediterranean diet.
The Mediterranean Diet Study
The Mediterranean diet has long been celebrated for its heart and liver-healthy benefits. Characterized by plentiful vegetables, fruits, whole grains, legumes, olive oil, fish, moderate dairy, and limited red meat, it’s consistently associated with reduced rates of metabolic syndrome, type 2 diabetes, and NAFLD.
A recent controlled study examined how a Mediterranean-style diet, when augmented with pentadecanoic acid (C15:0), impacted participants with fatty liver conditions. C15:0 is an essential fatty acid that is consistently associated with improved long-term health, better cardiovascular health, improved liver health, lower LDL cholesterol, stronger cell membranes, and improved mitochondrial function.
The study looked at three groups of people, all of whom had fatty liver disease. One group adhered to a Mediterranean-style diet, one group adhered to the Mediterranean-style diet and supplemented with C15:0, and the control group neither adhered to the diet nor supplemented with C15:0. All three groups were instructed to reduce caloric intake to 1000-1500 calories per day.
The results?
- All three groups lost weight and saw improvements in liver fat and enzymes, cholesterol numbers, and A1C levels.
- The group that adhered to the Mediterranean diet had a greater reduction in body weight and liver fat, lower cholesterol and triglycerides, and further improved liver enzyme function.
- The group that adhered to the Mediterranean diet and supplemented with C15:0 had significantly more total fat loss, lost more visceral adipose tissue, and had lower LDL cholesterol compared to both groups.
It is difficult and may not be ideal to rely on drastic caloric restriction or extreme diets over the long term. For individuals at risk for fatty liver disease, combining the Mediterranean diet with increased levels of C15:0 may be a good option to support healthy liver function..
How To Get Enough C15:0
C15:0 is found primarily in whole dairy products like whole milk and full-fat butter. This explains why many of us are deficient in this essential nutrient. After all, who do you know that still drinks whole milk?
Even though whole milk contains trace amounts of C15:0, it also contains a lot of unhealthy fats that are not good for your liver or your overall health. In addition, it packs a wallop of calories and excess sugars from lactose.
A solution? A C15:0 supplement. By supplementing pentadecanoic acid, you get the good fat without the bad. Combined with the Mediterranean diet, it’s a smart way to support your liver, especially if you are at risk for fatty liver disease.
