Mediterranean Diet For Fatty Liver In 2024: How Will It Help?

The Mediterranean diet focuses on abundant fruits, vegetables, whole grains, legumes, nuts, and omega-3 fatty acids while limiting trans fats and red meat. It’s a way of eating inspired by the countries bordering the Mediterranean Sea. Recent research suggests that a Mediterranean diet may play a role in preventing and managing fatty liver disease and other health benefits. Let’s explore how diet affects a fatty liver, the benefits of the Mediterranean diet for fatty liver, and ways to prevent fatty liver disease.

How Does Diet Affect Fatty Liver?

Many health concerns are linked to a person’s diet. A 2020 study on high-fat^[1] vs. high-carbohydrate diets in rats gives new insights into how the liver adapts to the nutrients in our diet. With a predominantly high-fat Western diet, there is an increased risk of developing conditions like:

• Obesity — Excess weight is now considered a global epidemic by the World Health Organization.^[2] 
• Metabolic syndrome^[3] — Metabolic dysregulation conditions increase the risk of developing insulin sensitivity or cardiovascular disease.
• Nonalcoholic fatty liver disease — NAFLD — Is now considered the leading chronic liver disorder^[4] in Western countries.

High saturated fat diets^[1] cause excess fat accumulation in the liver, referred to as a fatty liver. This results in liver damage. The liver then adapts to the heavy fat condition by controlling specific gene activity and altering the DNA sequences. Ultimately, the liver becomes impaired and can’t break down food or remove waste.

Benefits Of The Mediterranean Diet For Fatty Liver

A fatty liver diet,^[5] similar to the Mediterranean diet, is created around these basic principles: 

• Unlimited low-glycemic whole grains, vegetables, fresh fruit, olive oil, and nuts.
• Moderate fish, white meat, and legumes.
• Limited red meat, processed meat, and sweets.
• Avoid foods with a lot of sugar, especially fructose.
• Maintenance of a healthy weight.

These principles mean the diet is rich in beneficial compounds loaded with anti-inflammatory and antioxidant properties. 

A fatty liver diet or one similar, such as the Mediterranean diet, is key to preventing or reversing nonalcoholic fatty liver disease. And people who follow the Mediterranean diet closely may have up to 80% less liver fat accumulation^[6] than those who follow other dietary habits.

So, according to studies, a Mediterranean diet may provide the following benefits^[7] for nonalcoholic fatty liver disease — provided no alcohol, or only moderate intakes of wine, is included.

Flavonoids

These natural substances^[8] give fruits and veggies much of their color and flavor. They provide many health benefits, including protecting the liver from the effects of excess liver fat. Flavonoids^[9] also help regulate lipid metabolism, intestinal flora, and other destructive metabolic disease progressions.

Non-Flavonoids

Red wine, recommended on the Mediterranean diet, contains non-flavonoids, like resveratrol,^[10] that protect the liver in healthy adults through their antioxidant and anti-inflammatory properties. While more studies are needed, non-flavonoids may have the potential to help improve liver health. It might be noted, however, that traditionally alcohol consumption is not advised if you have NAFLD.^[11] However, a recent study challenged this notion allowing^[12] for moderate consumption of wine (as recommended by the Mediterranean diet) in successfully treating NAFLD.

Antioxidants

Many vitamins present in the Mediterranean diet are considered dietary antioxidants. They can help reduce cellular stress and restore liver health. Vitamins C, D, and E positively affect fatty liver diseases.

Carotenoids

Carotenoids, like lycopene,^[13] are found in many fruits and vegetables common in the Mediterranean diet. These compounds are a natural class of fat-soluble pigments that act as antioxidants. Carotenoids may be protective against excess liver fat.

Monounsaturated Fatty Acids

Monounsaturated fatty acids can help the liver process fats and prevent fatty liver disease. A diet with monounsaturated and polyunsaturated fatty acids helps balance the omega-6 to omega-3 fatty acids ratio. This may help improve lipid levels in the blood, reduce fat accumulation, and regulate glucose levels.

Gut Microbiota

Gut bacteria, or microbiota, are crucial in developing nonalcohol fatty liver disease. Gut bacteria influence obesity, insulin resistance, and liver inflammation. 

High dietary fiber in a Mediterranean diet can increase beneficial gut microbiota and decrease problematic bacteria. This can help alleviate obesity, inflammation, and metabolic diseases like diabetes.

Foods To Include In Mediterranean Diet For Fatty Liver

Including nutrient-dense foods in your Mediterranean diet can help provide the necessary nourishment to promote a healthy liver and manage the fatty liver disease. Here are some key foods to consider adding to a balanced diet:

• Fatty Fish — Omega-3 fatty acids-rich fish like salmon, sardines, and mackerel can help reduce inflammation and promote liver health.
• Olive Oil — Replace saturated fats with healthy fats like olive oil containing anti-inflammatory compounds and beneficial monounsaturated fats.
• Colorful Vegetables — Include a variety of vegetables such as leafy greens, tomatoes, bell peppers, and broccoli to support liver function with antioxidants and added fiber.
• Whole Grains — Opt for whole grains like quinoa, brown rice, and whole wheat bread for extra fiber and powerful nutrients that help stabilize blood sugar levels.
• Legumes — Lentils, chickpeas, and beans are excellent sources of plant-based protein, fiber, and antioxidants that can help reduce liver fat.
• Nuts and Seeds — Almonds, walnuts, chia seeds, and flaxseeds help provide healthy fats, fiber, and essential nutrients for liver health.
• Fruits — Enjoy a variety of fruits like berries, citrus, and apples loaded with vitamins, minerals, and antioxidants, which support liver function.

Make sure to include these superfoods for your liver in your Mediterranean diet recipes for fatty liver. A complete Mediterranean diet for a fatty liver meal plan and liver support supplements may be just what you are looking for to maintain a healthy weight and restore your liver health.

Foods To Avoided To Maintain Healthy Liver

Avoiding certain foods^[14] that can strain this vital organ to maintain a healthy liver is essential. These include:

• Alcohol — Excessive alcohol consumption can cause liver damage and contribute to developing alcoholic fatty liver disease. Moderate wine consumption^[12] has been used in limited studies on treating NAFLD with the Mediterranean diet but needs further research.
• Highly Processed Foods — These foods are often high in unhealthy fats, additives, and preservatives, burdening the liver and hindering its proper function.
• Sugary Drinks And Snacks — Consuming excessive sugar or high fructose corn syrup may lead to fatty liver disease and increase the risk of liver damage.
• High-Sodium Foods — Too much salt causes water retention and added stress on the liver.
• Red And Processed Meats — These are often high in saturated fats, leading to fatty liver disease and inflammation.

Other Ways To Prevent And Reverse Fatty Liver Disease

While maintaining healthy eating habits plays a crucial role in preventing and reversing fatty liver disease, there are additional measures that can help reduce major risk factors. 

• Regular physical activity.
• Maintaining a healthy weight and eating nutrient-dense foods.
• Managing chronic diseases like diabetes, high cholesterol, cardiovascular diseases, and blood pressure.
• Limiting exposure to toxins, such as certain medications, drugs, and environmental pollutants. 
• Consider adding supplements for a healthy liver, like milk thistle or omega-3 fatty acids.

These strategies may help reduce liver fat, improve health, or reverse a fatty liver. However, consulting a healthcare professional to develop a comprehensive plan for your needs is essential.

The Bottom Line

The Mediterranean diet offers a promising approach to managing and potentially reversing fatty liver disease. Its emphasis on whole foods, rich in fruits, vegetables, legumes, whole grains, lean proteins, and healthy fats, provides numerous benefits for liver health. 

Furthermore, it limits the intake of animal protein and alcohol while increasing the intake of plant-based foods and oily fish — healthy changes. The amount of wine a person with NAFLD can consume safely needs further research, but most clinicians still discourage its consumption.

The Mediterranean diet can help prevent and treat fatty liver disease when combined with regular physical activity, weight management, and other lifestyle modifications.

And finally, the Mediterranean diet emphasizes a balanced and sustainable lifestyle, making it easy to maintain long-term. Embracing this diet can be a delicious and sustainable way to support liver health and overall well-being.
