A healthy diet is essential for preserving liver function. Numerous meals contain substances that have been demonstrated to help protect against fat accumulation, enhance liver enzymes, and reduce oxidative stress and inflammation.
The creation of proteins, cholesterol, and bile as well as the storage of vitamins, minerals, and even carbohydrates are among the many biological processes that the liver is responsible for.
It also breaks down metabolic wastes and toxins like alcohol and narcotics. Sustaining liver health is essential for overall wellbeing.
Which foods are optimal for liver health?
1. Coffee
One of the healthiest drinks you can have to support liver function is coffee. One of the healthiest drinks you can have to support liver function is coffee. Research has demonstrated that coffee drinking prevents liver disease even in people who already have liver-related disorders.
For example, data from a 2016 scientific review shows that coffee drinkers are less likely to develop cirrhosis, or irreversible liver damage, in those who suffer from chronic liver disease.
According to a 2016 data analysis, coffee use may also help reduce the risk of developing a prevalent type of liver cancer.Reliable Source It also aids in the reduction of liver problems and inflammation.
These benefits seem to arise from its capacity to reduce the formation of fat and collagen, the 2016 analysis finds. The two most prevalent markers of liver disease are collagen and fat.
Additionally, coffee raises glutathione levels—a reliable source of antioxidants. The body naturally produces harmful chemicals called free radicals, which have the ability to harm cells. Antioxidants neutralize these molecules.
2. Tea
Although tea is generally thought to be healthy, research suggests that it may be especially good for the liver.
A 2020 analysis of fifteen studiesGreen tea was reported to lower liver enzyme levels in patients with nonalcoholic fatty liver disease (NAFLD).
Similar results were found in another study, which showed that giving green tea extract supplements to individuals with NAFLD for 12 weeks dramatically decreased their liver enzyme levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT).
In addition, a 2017 review Green tea drinkers had a lower risk of liver cancer, according to Trusted Source. The people with the lowest risk were those who drank four cups or more a day.
However, certain people should exercise caution and speak with a doctor before using green tea supplements, particularly if they have liver problems.
There are numerous reports of liver damage caused by supplements containing green tea extract.
3. Grapefruit
Antioxidants found in grapefruits naturally shield the liver. The two main antioxidants in grapefruit are naringin and naingenin.
It is known that grapefruit has two defensive qualities: it lowers inflammation and shields cells.
In line with a 2023 analysis Additionally, research has demonstrated that these antioxidants may be able to slow down the progression of hepatic fibrosis. Reliable Source An unhealthy disorder called hepatic fibrosis occurs when the liver accumulates an excessive amount of connective tissue. This is usually the outcome of ongoing inflammation.
There hasn't been any research on the effects of grapefruit or grapefruit juice itself, only its constituent parts. Furthermore, the 2023 analysis states that practically all research on grapefruit antioxidants has been done in animals.
However, the data available now indicates that grapefruit may protect the liver from harm and inflammation.
4. Blueberries and cranberries
The antioxidants called anthocyanins, which give berries their unique colors, are found in cranberries and blueberries. They have also been connected to numerous health advantages.
One study from 2021 For those with nonalcoholic fatty liver disease (NAFLD), taking a cranberry supplement for six months was reported to ameliorate hepatic steatosis, or fatty liver.
Furthermore, investigations conducted in test tubes have demonstrated that blueberry extract inhibits the growth of human liver cancer cells. To find out if humans can also feel this effect, more research is necessary.
Incorporating these berries into your diet on a daily basis will help ensure that your liver receives the antioxidants it requires to be healthy.
5. Grapes
A variety of advantageous plant components found in grapes, particularly in red and purple varieties, may improve liver function.
A 2020 investigation Although it's unknown if the findings of animal research translate to people, a study on rats reveals that grapes and grape juice can have a variety of health benefits.
Benefits may include:
-
Lowering inflammation
-
Preventing cell damage
-
Increasing antioxidant levels
A 2022 study, however, suggests that ingesting grape products could not have a substantial impact on liver enzyme levels or lead to better liver function.
Before grapeseed extract is suggested as a way to support liver health, more research is required.
6. Prickly pear
Opuntia ficus-indica, or prickly pear, is a well-known variety of edible cactus. The fruit and its juice are frequently consumed by people.
Traditional medicine has long employed it as a therapy for the following ailments:
-
Wounds
-
Fatigue
-
Digestive issues
-
Liver disease
According to a 2016 study, this plant's extract may be able to lessen hangover symptoms.
Because of its anti-inflammatory and antioxidant qualities, prickly pears may help shield the liver from alcohol poisoning.
More human research is required, particularly when prickly pear fruit and juice are used instead of extract. However, research to date has shown that prickly pears have a beneficial effect on the liver.
7. Beetroot juice
Beetroot juice holds betalains, serving as both nitrates and antioxidants.
According to research on animals, beet juice may help lessen oxidative damage and liver inflammation.
Even while research on animals appears encouraging, additional research is required to validate the beneficial effects of beetroot juice on liver function in humans.
8. Cruciferous vegetables
Vegetables classified as cruciferous are prized for their unique flavor and high fiber content. They also include a lot of healthy plant components.
Some examples of cruciferous veggies include:
-
Broccoli
-
Brussels sprouts
-
Cabbage
-
Kale
-
Cauliflower
Studies show that some compounds in cruciferous vegetables alter how the body detoxifies and protects itself from harmful pollutants.
Mice fed broccoli had a lower incidence of tumor development and fatty liver disease than mice in the control group, according to a 2016 study
In spite of the dearth of human studies, cruciferous vegetables seem to be a healthy dietary option for liver function.
9. Nuts
Nuts are abundant in certain essential nutrients (Reliable Source), such as:
-
Healthy fats
-
Antioxidants
-
Vitamin E
-
Beneficial plant compounds
These minerals have several positive health effects.
An examination conducted in 2019 A diet high in nuts was found to be associated with an increased risk of NAFLD.
Preliminary evidence indicates that nuts may be an important food group for liver function, but further high-quality studies are needed.
10. Fatty fish
Omega-3 fatty acids, which are good fats that have been linked to a lower risk of heart disease and can help reduce inflammation, are found in fatty fish.
An analysis from 2016. Omega-3 fatty acids have been found to have the potential to lower triglycerides and liver fat in patients with nonalcoholic steatohepatitis (NAFLD).
In addition to boosting your consumption of omega-3 fats, there are additional aspects to consider, even if eating fatty fish high in omega-3 fatty acids seems to be helpful for your liver.
A further important consideration is the ratio of omega-3 to omega-6 lipids.
The majority of people consume more omega-6 fats—found in butter and many plant oils—than is recommended.
According to one animal study, an excessively high omega-6 to omega-3 ratio can encourage the development of liver disease.
So, in addition to adding more heart-healthy omega-3 fats to your diet, it may also be a good idea to lower your intake of omega-6 fats that increase inflammation.
11. Olive oil
Olive oil is considered a healthy fat because of its many health benefits, including positive effects on cardiovascular and metabolic health. This also positively affects the liver. Following a Mediterranean diet rich in olive oil may help reduce the risk of fatty liver disease in older adults, according to a 2018 study.
Similar benefits of olive oil consumption in humans have been reported in a number of additional research, including reduced liver fat buildup and elevated blood levels of liver enzymes.
The early stages of liver disease include the buildup of fat in the liver. Because of its beneficial benefits on liver fat and other health-related issues, olive oil is a crucial component of a balanced diet.
