Top 8 Health Benefits of Artichokes and Artichoke Extract
This plant originated in the Mediterranean and has been used for centuries for its potential medicinal properties.
Its alleged health benefits include lower blood sugar levels and improved digestion, heart health and liver health.
Artichoke extract, which contains high concentrations of compounds found in the plant, is also increasingly popular as a supplement.
Here are the top 8 health benefits of artichokes and artichoke extract.
1. Loaded With Nutrients
Artichokes are low in fat while rich in fiber, vitamins, minerals, and antioxidants. Particularly high in folate and vitamins C and K, they also supply important minerals, such as magnesium, phosphorus, potassium, and iron.
One medium artichoke contains almost 7 grams of fiber, which is a whopping 23–28% of the reference daily intake (RDI).
These delicious thistles come with only 60 calories per medium artichoke and around 4 grams of protein — above average for a plant-based food.
Artichokes are low in fat, high in fiber, and loaded with vitamins and minerals like vitamin C, vitamin K, folate, phosphorus, and magnesium. They are also one of the richest sources of antioxidants.
2. May Lower ‘Bad’ LDL Cholesterol and Increase ‘Good’ HDL Cholesterol
A large review in over 700 people found that supplementing with artichoke leaf extract daily for 5–13 weeks led to a reduction in total and "bad" LDL cholesterol (6).
One study in 143 adults with high cholesterol showed that artichoke leaf extract taken daily for six weeks resulted in an 18.5% and 22.9% decrease in total and "bad" LDL cholesterol, respectively (7).
What's more, regularly consuming artichoke extract may boost "good" HDL cholesterol in adults with high cholesterol (5).
Artichoke extract affects cholesterol in two primary ways.
First, artichokes contain luteolin, an antioxidant which prevents cholesterol formation (9).
Second, artichoke leaf extract encourages your body to process cholesterol more efficiently, leading to lower overall levels (8).
Artichoke extract may reduce total and "bad" LDL cholesterol while increasing "good" HDL cholesterol.
3. May Help Regulate Blood Pressure
Artichoke extract may aid people with high blood pressure.
One study in 98 men with high blood pressure found that consuming artichoke extract daily for 12 weeks reduced diastolic and systolic blood pressure by an average of 2.76 and 2.85 mmHg, respectively (10).
How artichoke extract reduces blood pressure is not fully understood.
That said, it is unclear whether consuming whole artichokes provides the same benefits, as the artichoke extract used in these studies is highly concentrated.
Artichoke extract may help lower blood pressure in people with already elevated levels.
4. May Improve Liver Health
It also increases the production of bile, which helps remove harmful toxins from your liver (9).
In one study, artichoke extract given to rats resulted in less liver damage, higher antioxidant levels, and better liver function after an induced drug overdose, compared to rats not given artichoke extract (16).
Studies in humans also show positive effects on liver health.
For example, one trial in 90 people with non-alcoholic fatty liver disease revealed that consuming 600 mg of artichoke extract daily for two months led to improved liver function (17).
In another study in obese adults with non-alcoholic fatty liver disease, taking artichoke extract daily for two months resulted in reduced liver inflammation and less fat deposition than not consuming artichoke extract (18).
Scientists think that certain antioxidants found in artichokes — cynarin and silymarin — are partly responsible for these benefits (14).
More research is needed to confirm the role of artichoke extract in treating liver disease.
Regular consumption of artichoke extract may help protect your liver from damage and help relieve symptoms of non-alcoholic fatty liver disease. However, more research is needed.
5. May Improve Digestive Health
Artichokes are a great source of fiber, which can help keep your digestive system healthy by promoting friendly gut bacteria, reducing your risk of certain bowel cancers, and alleviating constipation and diarrhea (23, 24, 25).
Artichokes contain inulin, a type of fiber which acts as a prebiotic.
A study in 247 people with indigestion determined that consuming artichoke leaf extract daily for six weeks reduced symptoms, such as flatulence and uncomfortable feelings of fullness, compared to not taking artichoke leaf extract (29).
Artichoke leaf extract may maintain digestive health by boosting friendly gut bacteria and alleviating symptoms of indigestion.
6. May Ease Symptoms of Irritable Bowel Syndrome
Irritable bowel syndrome (IBS) is a condition that affects your digestive system and can cause stomach pain, cramping, diarrhea, bloating, constipation, and flatulence.
In one study in people with IBS, consuming artichoke leaf extract daily for six weeks helped ease symptoms. What's more, 96% of participants rated the extract equally as effective as — if not better than — other IBS treatments, such as antidiarrheals and laxatives (19).
Another study in 208 people with IBS discovered that 1-2 capsules of artichoke leaf extract, consumed daily for two months, reduced symptoms by 26% and improved quality of life by 20% (20).
Artichoke extract may relieve symptoms in several ways.
While artichoke extract seems promising for treating IBS symptoms, larger human studies are needed.
Artichoke leaf extract may help treat IBS symptoms by reducing muscle spasms, balancing gut bacteria and reduce inflammation. However, more research is necessary.
7. May Help Lower Blood Sugar
One study in 39 overweight adults found that consuming kidney bean and artichoke extract daily for two months lowered fasting blood sugar levels compared to not supplementing (30).
However, it is unclear how much of this effect was due to the artichoke extract itself.
Another small study indicated that consuming boiled artichoke at a meal reduced blood sugar and insulin levels 30 minutes after eating. Notably, this effect was only seen in healthy adults who did not have metabolic syndrome (31).
How artichoke extract reduces blood sugar isn't fully understood.
That said, artichoke extract has been shown to slow down the activity of alpha-glucosidase, an enzyme that breaks down starch into glucose, potentially impacting blood sugar (32).
Keep in mind that more research is needed.
Some evidence suggests that artichokes and artichoke leaf extract may lower blood sugar levels. However, more research is needed.
8. May Have Anticancer Effects
For example, silymarin was found to help prevent and treat skin cancer in animal and test-tube studies (36).
Despite these promising results, no human studies exist. More research is needed.
Test-tube and animal studies suggest that artichoke extract may fight the growth of cancer cells. However, no human studies exist, so more research is needed before conclusions can be drawn.
How to Add Them to Your Diet
Preparing and cooking artichokes is not as intimidating as it seems.
They can be steamed, boiled, grilled, roasted, or sautéed. You can also prepare them stuffed or breaded, adding spices and other seasonings for an extra burst of flavor.
Steaming is the most popular cooking method and usually takes 20–40 minutes, depending on the size. Alternatively, you can bake artichokes for 40 minutes at 350°F (177°C).
Keep in mind that both the leaves and the heart can be eaten.
Once cooked, the outer leaves can be pulled off and dipped in sauce, such as aioli or herb butter. Simply remove the edible flesh from the leaves by pulling them through your teeth.
Once the leaves are removed, carefully spoon out the fuzzy substance called the choke until you reach the heart. You can then scoop out the heart to eat alone or atop pizza or salad.
The edible parts of the artichoke include the outer leaves and heart. Once cooked, artichokes can be eaten hot or cold and served with different dipping sauces.
Supplement Safety and Dosing
However, there is limited data available. Risks include:
- Potential allergies: Some people may be allergic to artichokes and/or artichoke extract. The risk is higher for anyone allergic to plants from the same family, including daisies, sunflowers, chrysanthemums and marigolds.
- Pregnant or breastfeeding women: Pregnant or breastfeeding women are advised to avoid artichoke extract because of a lack of safety information.
- People with bile duct obstruction or gallstones: Anyone with these conditions should avoid artichokes and artichoke extract due to their ability to promote bile movement (37).
There is currently insufficient data to establish dosing guidelines.
However, typical doses used in human research range from 300–640 mg of artichoke leaf extract three times daily (7).
If you are unsure whether you should take artichoke extract, speak with your doctor for advice.
Side effects of artichoke extract are rare, though people with bile duct disorders and women who are pregnant or breastfeeding may wish to avoid it. Typical doses range from 300–640 mg three times daily.
The Bottom Line
Artichokes are an extremely nutritious, low-carb food that may provide numerous health benefits.
That said, evidence is mostly limited to studies using concentrated artichoke extract.
Regular consumption of artichoke extract may aid cholesterol levels, blood pressure, liver health, IBS, indigestion and blood sugar levels.
However, more research is needed to confirm these benefits.

Climate change, habitat loss and pollution are overwhelming our planet. Thankfully, these enormous threats are being met by a bold new wave of environmental activism.
Trump Makes Strange Claim About Water Efficient Toilets: 'People Are Flushing Toilets 10 Times, 15 Times'
President Donald Trump mocked water-efficiency standards in new constructions last week. Trump said, "People are flushing toilets 10 times, 15 times, as opposed to once. They end up using more water. So, EPA is looking at that very strongly, at my suggestion." Trump asked the Environmental Protection Agency (EPA) for a federal review of those standards since, he claimed with no evidence, that they are making bathrooms unusable and wasting water, as NBC News reported.

Former Monsanto Chairman and CEO Hugh Grant will have to testify in person at a St. Louis-area trial set for January in litigation brought by a cancer-stricken woman who claims her disease was caused by exposure to the company's Roundup herbicide and that Monsanto covered up the risks instead of warning consumers.
A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.
"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."
The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.
My god, White Island volcano in New Zealand erupted today for first time since 2001. My family and I had gotten off it 20 minutes before, were waiting at our boat about to leave when we saw it. Boat ride home tending to people our boat rescued was indescribable. #whiteisland pic.twitter.com/QJwWi12Tvt— Michael Schade (@sch) December 9, 2019

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.
The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.
Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.
"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."
Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.
Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.
"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.
"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."
The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.
Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
