Foods & Nutrition for Supporting Liver Health

It’s a popular belief that certain special foods can act as ‘liver detox’ foods, and liver diets and cleanses are in strong demand.

But despite the hype, there’s no strong evidence to support that any specific food or beverage, diet or cleanse can ‘detoxify’ the liver. The liver and kidneys remove toxins and waste as part of their normal functions in the body and, according to Healthdirect, there’s also no evidence to show that liver detox programs or cleanses assist or improve the ability of these organs to complete these functions.

But food still matters!

As an important part of a healthy lifestyle, what you eat and drink over time can support liver health. But what works is an overall balanced eating pattern, not a handful of foods with special cleansing powers. This article will help you to understand:

• Why detox teas and supplements should be approached with caution,
• Australian guidance on a liver-healthy diet,
• Where coffee fits in,
• Which foods and drinks need to be limited to support liver health, and
• When you need to see a doctor or healthcare provider.

Do 'Liver Detox Foods' Actually Detox the Liver?

No.

The premise behind ‘liver cleansing’ foods is that the liver accumulates toxins and needs assistance to flush them out, and that certain foods and drinks can do that job. But Healthdirect's position is clear: there is no evidence to show that special foods, liver detox programs or cleanses improve liver function or health.

The liver and kidneys continuously remove toxins and wastes from the body as part of their normal function, without needing a special diet or specific foods to trigger the process. Foods labelled as ‘detoxifying’ are usually perfectly healthy, whole foods, but they don't have the special effects they're claimed to have. Rather than focussing on foods claimed to be ‘detoxifying’, improving your overall eating pattern is what will improve your overall health.

What Does a Liver-Healthy Eating Pattern Look Like?

The Australian Dietary Guidelines recommend a wide variety of minimally processed, nutritious foods from the core food groups every day. These overall dietary principles are also recommended by Liver Foundation Australia, who endorse varied, whole-food eating habits including:

• Vegetables and fruit,
• Wholegrains,
• Beans, legumes, nuts and seeds,
• Healthy fats (like olive oil),
• Healthy, lean protein from both animal and vegetarian sources,
• Plenty of water, and
• Limiting processed foods, sugary drinks and alcohol.

Vegetables and Fruit

Vegetables and fruit are the foundations of a varied, nutrient-dense diet.

The Australian Dietary Guidelines recommend eating a wide variety of vegetables and fruit, and Liver Foundation Australia includes fresh produce in its liver health recommendations.

A variety of vegetables and fruit are a valuable part of a healthy diet, but no particular types have a special ‘detox’ effect on the liver.

Wholegrains

Wholegrains such as oats, barley and brown rice form part of the balanced eating pattern recommended by the Australian Dietary Guidelines. Liver Foundation Australia also includes wholegrains in its liver-health recommendations.

No specific grains have special ‘detox’ effects, but their nutrient value and fibre content benefit overall health.

Beans, Legumes, Nuts and Seeds

Australian healthy-eating guidance includes beans, legumes, nuts and seeds as valuable protein sources. Nuts and seeds in particular are also sources of healthy fats in the diet. Liver Foundation Australia includes these foods in its liver-health recommendations, too.

Like all healthy foods, they support general health rather than specifically ‘detoxify’ the body.

Healthy Fats

Liver Foundation Australia includes olive oil, nuts and seeds as sources of healthy fats in their dietary guidelines.

For overall health, the Australian Dietary Guidelines also advise limiting foods high in saturated fat, like fried foods, cakes and pies and fatty cuts of meat.

There are no particular sources of fat that ‘detoxify’ the body, but choosing healthy sources helps support overall health.

Healthy, Lean Protein Sources

Both the Australian Dietary Guidelines and Liver Foundation Australia include lean protein foods like meats, poultry, fish, vegetarian alternatives and soy foods in their dietary recommendations.

Protein foods do not specifically repair or detoxify the liver, but support overall nutrition and health.

Water as an Everyday Drink

The Australian Dietary Guidelines recommend drinking plenty of water each day, and Liver Foundation Australia's guidance to limit sugary drinks is also important.

However, drinking extra water does not flush toxins from the liver.

What About Coffee and Liver Health?

Coffee is one of only a few foods or drinks with associated liver-specific research evidence.

Liver Foundation Australia highlights research linking regular coffee consumption with a lower risk of some adverse liver outcomes. However, this is association evidence, and not proof that coffee protects or cleanses the liver.

Whether coffee is a healthy choice for you depends on your own health, preferences and circumstances. If you have a liver condition or health concerns, discuss coffee with your doctor or healthcare provider.

Foods and Drinks to Limit for Health

Just as no specific foods detoxify the liver, there are no ordinary foods that can be considered 'toxic'.

An evidence-based approach to food focuses on the balance of what you regularly eat and drink daily, over time. There are some foods and drinks that are best limited according to the Australian Dietary Guidelines and Liver Foundation Australia, including:

• Foods high in saturated fat,
• Foods with added salt,
• Foods with added sugars,
• Fried foods,
• Processed meats,
• Sugar-sweetened drinks, and
• Alcohol.

It’s important to keep these foods in check, but there is no evidence to support restrictive detox plans or cutting out entire food groups.

What About Liver Detox Teas, Cleanses and Supplements?

Detox teas, cleanses, and liver tonics are marketed on the idea that the liver needs help clearing toxins. However, Healthdirect finds no evidence that liver detox programs or cleanses improve health, and Liver Foundation Australia notes that liver tonics and supplements promoted for detox have limited evidence to support their claims.

Liver Foundation Australia also warns that some medicines, herbal products and dietary supplements can damage the liver. If you are considering a supplement promoted for liver health or detox, discuss it with your doctor, healthcare provider or pharmacist first.

When Should You Speak With a Doctor About Liver Health?

For most of us, supporting liver health simply means following general healthy-eating guidance, which does not require medical supervision. If you have concerns about your liver, risk factors for liver problems, or symptoms that worry you, speak with your doctor or health provider, who can assess your situation properly.

If you have a diagnosed liver condition, general dietary guidance may not be appropriate for your circumstances. A doctor, healthcare provider or dietitian can advise whether you need more individualised dietary guidance.

Frequently Asked Questions

What foods detox your liver?

No individual food has been shown to detox the liver. The liver and kidneys already remove toxins and wastes as part of normal function.

According to Healthdirect, there is no evidence that liver detox programs or cleanses improve health, and Australian dietary guidance supports adopting a balanced eating pattern built on vegetables, fruit, wholegrains, legumes, suitable protein foods and healthier fats for overall health.

Can you cleanse your liver naturally?

There is no reliable evidence that a special dietary liver cleanse improves health via a ‘detox’ effect.

Healthdirect has found no evidence that liver cleanses or detox diets improve health, and Liver Foundation Australia also advises that there is very limited evidence to support the efficacy or safety of detox tonics and supplements.

Some herbal and dietary supplements may damage the liver and should be approached with caution, under medical advice.

The evidence-based approach to supporting liver health is to eat a balanced, healthy diet, limiting processed foods, sugary drinks and alcohol.

What foods are part of a liver-healthy diet?

A liver-healthy diet is a varied pattern of ordinary healthy foods, not a short list of special 'healthy liver' foods.

Both the Australian Dietary Guidelines and Liver Foundation Australia recommend including plenty of vegetables and fruit, wholegrains, legumes, nuts and seeds, fish and high quality protein sources, healthier fats such as olive oil, and water, while limiting processed foods, sugary drinks and alcohol.

Is coffee good for your liver?

Liver Foundation Australia highlights research showing favourable associations between regular coffee consumption and a lower risk of some adverse liver outcomes. This is association research, not proof that coffee specifically protects or detoxifies the liver.

How much coffee suits you depends on your health, preferences and circumstances, so if you have a liver condition or other concerns about liver health, speak to your doctor, health provider or dietitian.
