Foods That Will Detox Your Liver

The liver is a powerhouse organ, and to keep it functioning at peak performance, a nutritious diet is key. Incorporating specific foods can significantly enhance liver health, providing the necessary nutrients to support detoxification processes and reduce the risk of liver-related diseases. From antioxidant-rich fruits to fiber-packed vegetables, these dietary choices not only boost liver function but also contribute to overall well-being.

In this blog, we speak to Josiah Wagler, D.O., an abdominal transplant surgeon at INTEGRIS Health Nazih Zuhdi Transplant Institute, to learn more.  

“The liver is crucial to countless metabolic functions, making it essential to prioritize our health through watching what we eat and avoiding harmful habits,” Wagler says. “As the body’s detoxification center, it plays a key role in filtering toxins, producing vital proteins and storing energy. Protecting liver health is not just about preventing disease, it’s about supporting our overall wellness and ensuring our body operates as its best version of oneself.” 

The importance of liver health

What to know: Maintaining liver health is essential for detoxification, metabolism and overall wellness. Liver damage can impair nutrient processing, toxin filtration and infection defense, leading to significant health problems.

The liver is a large, vital organ located in the upper right abdomen, beneath the diaphragm.

• It has several essential functions crucial for maintaining overall health.

The process of detoxification removes toxins from the blood and metabolic waste, making it a key player in filtering and neutralizing harmful substances.

• The liver receives blood from the digestive tract and filters out toxins, drugs and other substances.
• The liver uses enzymes to convert the toxins into less harmful compounds.

Metabolic function is also a key role of the liver.

• The liver metabolizes carbohydrates, proteins and fats.
• As part of carbohydrate metabolism, the liver helps regulate blood sugar by storing excess glucose from carbohydrates as glycogen and releasing it when needed.
• As part of fat metabolism, the liver breaks down fats to produce energy and synthesizes cholesterol and lipoproteins.
• As part of protein metabolism, the liver processes amino acids and converts them into energy or other compounds.

Bile production originates in the liver.

• This digestive liquid is composed of bile acids, cholesterol, bilirubin (a breakdown product of red blood cells), water and electrolytes.
• Bile emulsifies fats into smaller droplets, aiding enzyme digestion and the absorption of fat-soluble vitamins (A, D, E and K).

Nutrient storage occurs in various forms to ensure the body has a steady supply when needed. 

• Stored glycogen can be quickly converted back into glucose and released into the bloodstream to maintain blood sugar levels between meals or during physical activity.
• Both fat-soluble vitamins (A, D, E and K) and water-soluble vitamins (B12) are stored and released as needed.
• Minerals such as iron and copper help produce red blood cells and assist with enzymatic reactions, respectively.

Synthesis of proteins occurs in the liver.

• Production includes albumin (to maintain blood volume and pressure) and clotting factors (to help in blood coagulation).

Foods for liver health

At a glance: Foods that support liver health are typically high in antioxidants, fiber, healthy fats and essential vitamins and minerals. Whether you have a healthy liver or liver disease, eating healthily plays a role in protecting the liver.

Cruciferous vegetables contain sulfur-containing compounds called glucosinolates that can help with liver detoxification.

• Examples include broccoli, brussels sprouts and cauliflower.

Garlic contains sulfur compounds such as allicin, s-allyl cysteine and diallyl disulfide that activate enzymes to flush toxins out.

• Garlic also has selenium, a mineral essential for detoxification.

Grapefruit is high in vitamin C and antioxidants to boost the production of liver enzymes needed in detoxification.

• Naringenin and naringin are two antioxidants that help protect the liver by reducing inflammation and preventing oxidative damage.
• Other citrus fruits, such as oranges, lemons, limes and tangerines, are also good for liver health.

Beets are packed with antioxidants and nutrients like betaine, a compound that supports liver function and helps reduce inflammation. 

• Betaine aids in the metabolism of homocysteine, an amino acid that, at high levels, can be harmful to the liver.

Leafy greens are high in chlorophyll, which assists in neutralizing heavy metals and other toxins.

• Examples include spinach, kale, swiss chard, mustard greens, bok choy and arugula.

Green tea is rich in catechins, a type of flavonoid known for its antioxidant properties.

• Catechins help neutralize free radicals, reducing oxidative stress and potentially lowering the risk of diseases.

Avocados have healthy fats and glutathione to help filter out harmful toxins and promote liver health.

• Monounsaturated fats found in avocados can reduce bad cholesterol levels and decrease the risk of liver damage.
• Glutathione is an antioxidant that protects the liver from oxidative stress.

Turmeric is a spice that contains curcumin, which has anti-inflammatory and antioxidant properties.

• The anti-inflammatory effects in curcumin can help reduce liver inflammation, while antioxidants protect against oxidative stress.

Walnuts are high in amino acids like arginine, which help the liver detoxify ammonia.

• Walnuts also contain the antioxidant glutathione and omega-3 fatty acids.
• Omega-3s have anti-inflammatory properties and help regulate lipid metabolism to reduce fat accumulation in the liver.

Apples are rich in pectin, a type of soluble fiber that promotes regular bowel movements.

• Since bowel movements help remove toxins from the body, this lowers the burden on the liver to remove harmful substances.
• Pectin binds to bile acids in the intestines, prompting the liver to use cholesterol to produce new bile acids, thus supporting liver health.

Olive oil contains monounsaturated fats, antioxidant properties and has anti-inflammatory properties to boost liver health.

• Use cold-pressed, organic olive oils, as the minimal processing preserves the natural nutrients, antioxidants and healthy fats.

How to take care of your liver

Key points: Taking care of your liver involves adopting a balanced lifestyle and making conscious choices that promote health. 

Maintain a healthy diet by eating the foods mentioned above.

• In general, fruits, vegetables, whole grains and lean proteins help reduce saturated fats and sugars that can impact the liver.

Exercise regularly for at least 150 minutes of moderate exercise per week.

• Physical activity helps decrease liver fat.
• It also improves insulin sensitivity and enhances blood flow, two areas that help the liver function properly.

Limit alcohol and avoid smoking and drug use, as these substances can lead to liver damage.

• Smoking contributes to liver damage and increases the risk of liver diseases.
• Avoid sharing needles or injecting drugs to reduce the risk of liver infections.

Exercise caution with using medications that can harm the liver.

• High doses or chronic uses of acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) can produce toxic metabolites that may damage liver cells.
• Statins used to lower cholesterol can elevate liver enzymes and lead to stress or damage.
• Certain antibiotics, such as amoxicillin-clavulanate, can cause liver injury.
• Antifungal medications such as ketoconazole can be hepatotoxic and cause liver damage when used for prolonged periods.

Prevent liver infections by getting vaccinated and practicing safe sex.

• Vaccinations for hepatitis A and B can prevent infections that lead to liver disease.
• If you’re sexually active, use protection to avoid sexually transmitted infections that can affect the liver.

Stay hydrated by drinking plenty of water.

• Fluids help support liver health by flushing out toxins.
• The Academy of Nutrition and Dietetics recommends 100 ounces/12.5 cups for men and 73 ounces/9 cups for women, although these numbers will fluctuate on individual activity and metabolism.

Next steps: Your liver works tirelessly to keep you healthy—support it with the right foods and lifestyle choices. If you have any specific concerns, contact your doctor for personalized advice.
