10 Foods That Cleanse And Protect The Liver Naturally
Liver-Friendly Foods For Cleansing
Your liver undergoes damage from high-fat, refined foods, alcohol, and long-term medicine usage. Broccoli, beetroot, amla, berries, omega-3 fish, ginger, garlic, and coffee are some of the most potent liver-detoxifying foods. While tuna and berries lower fat deposition in the liver, treating NAFLD, broccoli and ginger fight free radicals by raising the natural antioxidant levels. Both garlic and coffee protect against alcohol-related liver damage.
Did you know that your liver is the most important detox center in the body? Harmful chemicals from everything you ingest or inhale – food, drinks, medicine, or smoke – transform into less harmful, water-soluble substances in the liver in a 2-phase process and are then excreted. But the first phase of the detoxification process also generates free radicals, which then go on to damage cells and cause inflammation. If the free radicals and their damage are not countered and repaired, over time, they affect the liver’s health and functioning. This is why antioxidants are must in a liver detox diet. Just as important are foods that lower cholesterol, especially the harmful LDL cholesterol, and triglycerides, a type of fat. Here are the 10 foods, herbs, drinks, and spices that help the liver carry out its detox functions and protect it from damage.1
1. Broccoli And Brussels Sprouts
There’s wisdom in eating your greens, especially cruciferous ones like broccoli, Brussels sprouts, cabbage, watercress, and cauliflower. These contain helpful chemicals like sulforaphane, indole-3-carbinol, and 1-cyano-2-hydroxy-3-butene (CHB) which block cancer-causing chemicals – such as NNK in cigarette smoke. These also increase the levels of natural antioxidant enzymes essential for the detoxification process.2 When the body is overloaded with toxins, the levels of natural antioxidants go down, thereby slowing down the detoxification process in the liver.
Best for protecting the liver against damage
Eating too much refined and sugary foods also increase the harmful LDL cholesterol and a type of fat called triglycerides. Since the liver helps remove excess LDLs from the body, an LDL overload can strain it. Triglycerides, on the other hand, collect in the liver, causing fatty liver or non-alcoholic fatty liver disease (NAFLD). This raises your risk for liver inflammation (steatohepatitis), which leads to cirrhosis, liver failure, and liver cancer. Cruciferous vegetables also have cholesterol-like compounds called phytosterols which can lower both high cholesterol and triglyceride level.3
How much should you have? Have 1.5–2.5 cups of dark green veggies, including cruciferous ones, every week.4 If you have a hypothyroidism problem, cook these vegetables well before consuming them.
Best as a preventive against oxidative stress in the liver
Here’s what the violet on your rainbow plate of veggies can do for your liver. Betalains, the antioxidant pigments in beetroot, along with flavonoids, phenolic acids, and vitamin C, protect the liver against oxidative stress from carcinogens or cancer causing agents.
If you have beetroots regularly, it could modify your body’s metabolism (by reducing the activity of the enzymes that increase free radicals during detoxification) in such a way that your liver would be protected from toxic compounds.5
How much should you have? Beet juice made from 1 large beetroot is safe for daily consumption. Drink the juice 2–3 days a week.
3. Fish Like Tuna And Salmon
Omega-3 fats or the polyunsaturated fats found in marine fish like tuna, salmon, trout, or mackerel, to name only a few, are good for the liver. As preventives, they inhibit triglyceride synthesis in the liver. But they can also reduce liver fat in people with NAFLD, who also have high cholesterol and triglyceride levels. Omega-3 fats also increase the levels of HDL, the good cholesterol.6
Best for NAFLD patients
Other sources of omega-3 fats are fortified eggs, walnuts, and avocados. But it’s not enough to include these in your diet; you also need to cut down on omega-6 fats like vegetable oils.
How much should you have? The American Heart Association recommends at least 2 servings (3.5 oz per serving) of fatty fish per week if you don’t have a heart condition. You could also have fish oil in a daily dose of 2–4 g if you have high triglyceride levels.7
4. Amla Or Indian Gooseberry
Amla or the Indian gooseberry (Emblica officinalis) is a natural liver revitalizer. It is commonly used in Ayurveda for treating enlarged livers.8
Best for those with jaundice, enlarged livers, and NAFLD
Researchers have found that this fruit rich in vitamin C can be used to treat liver problems like jaundice. Remember, vitamin C is a potent antioxidant.
Since it also lowers cholesterol and triglycerides, amla is also good for anyone with non-alcoholic fatty liver disease.9
How much should you have? You can have the fresh fruit or dried fruit powder. The standard dose used in experiments is 1 to 3 g fruit powder. You can also have 1 fruit a day, raw or in a juice form, preferably spread through the day.
Cleanse your body naturally by giving it plenty of berries rich in polyphenols and anthocyanins, the antioxidant pigments that give them their unique colors. These nutrients are potent anti-inflammatory agents.
Best for preventing NAFLD
One study found that lingonberries, black currants, and bilberries were especially effective in preventing the accumulation of fat in the liver. Lingonberries, in particular, decreased body fat significantly in animals that were on a high-fat diet.10
How much should you have? The standard serving size for berries is 1/2 cup frozen or fresh fruit or 4 oz juice daily. There’s no strict upper limit; however, too many berries might have side effects on people on medicines for blood-thinning and diabetes.
The warm earthy heat of ginger doesn’t just spice up your meal but can also be really good for the liver. This root spice, with antioxidant like gingerols and shogaols, acts on your digestive system, increasing enzyme secretions and boosting metabolism and circulation.
It has been seen to lower oxidative damage in the liver caused by free radicals, whether due to environmental toxins or due to long-term use of medication. It also increases the levels of natural antioxidants in blood.11
Best for those with NAFLD and liver damage due to medication or drugs
Since ginger can decrease triglycerides, total cholesterol, and the LDL cholesterol, it is a good addition to the diet for people who are at risk of NAFLD.12
How much should you have? For a healthy adult, up to 4 g ginger is considered safe, whether eaten raw, cooked, or as a tea. For pregnant women, however, the dosage is limited to 1 g.13
7. Garlic And Onion
Odd as it may seem, odorous vegetables of the Allium species like garlic and onion are great for liver health. The sulfur compounds in them, responsible for that distinctive smell, help stimulate liver enzymes responsible for detoxification. They also have antioxidants called flavonoids which can both block and suppress the function of free radicals.14 15
Best for patients with alcohol-induced liver damage
The best part about garlic, however, is its ability to reduce alcohol-related liver damage (alcoholic steatohepatitis), whether taken raw, as garlic oil, or as an aged black garlic extract.16 17 Onions too have shown similar effect on alcohol-induced liver damage.18
How much should you have? Most studies use garlic in a dose of 600 to 1200 mg. However, a few cloves a day is well within the tolerable limit. Make sure you crush the cloves before eating them or cooking them to release the bioactive sulphur compound called allicin. There’s no known upper limit on onions.
8. Coffee And Tea
Coffee lovers, it’s time to rejoice! Finally, there’s a study that tells us your oh-so-favorite morning drink is good for you! If you suffer from liver diseases, a moderate consumption of coffee can actually decrease the progression of the illnesses. For patients who are scheduled for liver biopsy, caffeine is known to reduce the development of cirrhosis. Although it’s not entirely clear why caffeine helps, we do know that it reduces the risk of developing liver diseases. Thanks to kahweol and cafestol, the 2 naturally occurring substances in coffee, coffee reduces the risk of liver cancer.19.
Best for patients with cirrhosis
A very recent study on finds that drinking around 3 cups of coffee and herbal tea regularly led to less scarring of the liver. Continuous scarring of the liver due to inflammation and death of liver cells leads to liver fibrosis.20
How much should you have? Just 2 cups of coffee per day is considered the ideal amount, and anything over 5 cups is not advised.21 Also remember not to have coffee within 2 hours before sleep.
9. Milk Thistle
Best for alcoholic hepatitis and can cure hepatitis C
A natural herbal remedy, the milk thistle can be enjoyed in a herbal tea that’s great for your liver. Some fans of the ingredient also use it in smoothies and salads. Silymarin, an antioxidant and anti-inflammatory flavonoid in the seeds, offers protection to the liver not just from toxins in your diet but also from drugs like acetaminophen that damage the liver when taken in high doses.
Milk thistle may also help against alcoholic hepatitis, cirrhosis, and hepatitis C. Research suggests it may even help rejuvenate and repair your liver by aiding the growth of new cells.22
How much should you have? Around 300 mg milk thistle thrice a day is the ideal amount for consumption.23
No cleanse list would be complete without the anti-inflammatory and natural healing spice turmeric. Ayurveda and Chinese Medicine have both been using it to treat liver problems for centuries.24
Best for preventing fat accumulation and inflammation
The curcumin in turmeric prevents fat accumulation in the liver, as seen in several animal studies. Test animals consuming curcumin through their diet had lower cholesterol and triacylglycerol concentrations in the liver, showing the potential of including the ingredient in your diet.25 It also raises the natural antioxidants involved in the detoxification process in the liver.
How much should you have? In Asian and Indian cuisine, turmeric powder is an essential condiment. Include 1.5–3 g powdered turmeric root every day. However, if you suffer from inflammatory bowel syndrome, reduce the dosage to 1–1.5 g.26
