Diet plays a key role in maintaining liver health. Many foods contain compounds that may help improve liver enzyme levels, protect against fat buildup, and reduce inflammation
The liver is involved in many body processes, including producing proteins, cholesterol, and bile, and storing vitamins, minerals, and carbohydrates
It also breaks down toxins such as alcohol, medication metabolites, and natural metabolic byproducts
Keeping your liver in good condition is important for maintaining health
While no single food can “detox” the liver, a nutrient-rich diet may help support normal liver function
Some foods to consider adding to your diet to support liver health include:
Blueberries and cranberries
Blueberries and cranberries contain anthocyanins. These are a type of antioxidant that gives berries their distinctive colors and are linked with many health benefits
A 2021 study
found that taking a cranberry supplement for 6 months improved hepatic steatosis, or fatty liver, in people with non-alcoholic fatty liver disease (NAFLD)
Another 2021 review of studies suggests that anthocyanin supplementation has a beneficial effect on liver enzymes
Another interesting finding is that blueberry extract seems to inhibit the growth of human liver cancer cells in vitro (test-tube studies). However, more studies are needed to determine whether this effect can be replicated in animal or human studies
Cruciferous vegetables
Cruciferous vegetables are known for their high fiber content and distinctive taste. They’re also rich in beneficial plant compounds
Some examples of cruciferous vegetables include:
Studies suggest that cruciferous vegetables contain compounds that alter detoxification and protect against harmful substances
Scientists continue to research
the role of cruciferous vegetables in cancer prevention, including liver cancer
Though human studies show mixed results, early animal and in vitro studies are promising
Nuts are rich in several key nutrients
, including:
- healthy fats
- antioxidants
- vitamin E
A 2019 study
found a diet higher in nuts to be associated with a reduced risk of NAFLD. While more high quality studies are needed, preliminary data point to nuts being an important food group for liver health
Fatty fish
Fatty fish contain omega-3 fatty acids, which are healthy fats that help reduce inflammation
A 2016 analysis
found that omega-3 fatty acids helped lower liver fat and triglycerides in those with NAFLD or nonalcoholic steatohepatitis
While consuming omega-3-rich fatty fish appears to be beneficial for your liver, adding more omega-3 fats to your diet is not the only thing to consider
The ratio of omega-3 fats to omega-6 fats is also important
Most people consume more than enough omega-6 fats, which are found in many plant oils and butter, but not enough omega-3
So, in addition to adding more heart-healthy omega-3 fats to your diet, it may also be a good idea to reduce your intake of omega-6 fats that promote inflammation
Olive oil
Olive oil is considered a healthy fat because of its many health benefits, including positive effects on the heart and metabolic health
It might also have a beneficial effect
on the liver
A 2018 study
suggests that following a Mediterranean diet rich in olive oil may be associated with a reduced risk of fatty liver in older adults
Several other studies have found similar effects of olive oil consumption in humans, including less fat accumulation
in the liver and improved blood levels of liver enzymes
Takeaway
Many factors can affect your liver’s health, but your diet is one way you can support it
Certain foods may offer specific benefits for your liver and are worth including in your diet to support good health
In addition to adding these foods, maintaining a healthy diet and other healthy lifestyle habits is key to overall well-being
