However, if you're new to juicing, you may find it difficult to determine which vegetables to choose.
Here are the 12 best vegetables to juice to improve your overall health.
Kale is a versatile leafy green with a mild flavor that pairs well with other fruits and veggies in juices.
This power-packed ingredient is a great source of several key nutrients, including vitamins A, C, and K (1).
Raw kale is also especially high in antioxidants, including beta-carotene.
Antioxidants neutralize harmful molecules called free radicals to help protect against conditions like heart disease (2Trusted Source). In fact, drinking kale juice has been shown to reduce heart disease risk factors, including LDL (bad) cholesterol.
One study in 32 men with high cholesterol levels found that drinking 5 ounces (150 ml) of kale juice daily for 3 months reduced LDL (bad) cholesterol by 10% and boosted heart-protective HDL cholesterol by 27% (3Trusted Source).
Kale is high in several important nutrients, including beta-carotene and vitamins A, C, and K. Plus, it has been shown to improve heart disease risk factors.
Due to their slightly sweet flavor and impressive nutrient profile, carrots are a perfect choice for juicing.
What's more, they're loaded with carotenoids, which are plant pigments that work as powerful antioxidants in your body. These include beta-carotene, lycopene, alpha-carotene, and lutein (5Trusted Source).
Studies show that eating a diet rich in carotenoids may be linked to a lower risk of degenerative eye diseases, heart disease, and certain types of cancer, including of the prostate (6Trusted Source, 7Trusted Source, 8Trusted Source, 9Trusted Source).
The sweetness of carrot juice combines well with other commonly juiced vegetables and fruits, such as citrus fruits, ginger, and beets.
Carrots are rich in vitamin A, biotin, and potassium. They're also high in carotenoids, which may be linked to a lower risk of eye disease, heart disease, and certain types of cancer.
In addition to their vibrant color and earthy flavor, beets add a host of health benefits to your daily juice.
In terms of nutrition, beets are packed with manganese, potassium, and folate (10).
They're also high in nitrates, a type of natural plant compound with powerful health effects.
Not only do beets make a delicious addition to juices but also their leafy green tops — called beet greens — are highly nutritious and can be juiced as well (14).
Beets are a good source of manganese, potassium, folate, and nitrates, which may help lower blood pressure and improve athletic performance and brain health.
Cabbage may not seem like an obvious choice for juicing, but it's a nutritious and delicious ingredient that works well in juices.
It's also classified as a cruciferous vegetable and closely related to other veggies like broccoli, kale, cauliflower, and Brussels sprouts.
Cabbage is high in vitamins K and C along with many other nutrients. As a cruciferous vegetable, it may help protect against diabetes, heart disease, and inflammation.
Spinach is a leafy green vegetable that brings a mild, fresh flavor to smoothies and juices.
Spinach is also rich in nitrates, which can benefit heart health (21Trusted Source).
One study in 27 people found that consuming spinach for 7 days significantly reduced systolic and diastolic blood pressure (the top and bottom numbers of a reading). High blood pressure is a major risk factor for heart disease (22Trusted Source).
Spinach is rich in vitamins A and C, as well as antioxidants and nitrates. It may reduce blood pressure and have antacid effects.
Broccoli is a cruciferous vegetable that's been tied to various impressive health benefits.
In particular, it's an excellent source of key micronutrients, such as potassium and vitamins A, B6, and C (24).
It also contains kaempferol, a powerful compound that has been shown to neutralize disease-causing free radicals, decrease inflammation, and reduce cancer cell growth in test-tube studies (25Trusted Source).
What's more, a recent study in 960 people noted that eating one serving per day of green vegetables rich in kaempferol and other antioxidants may slow age-related mental decline (26Trusted Source).
Toss broccoli heads and stems into your juicer for a nutritious addition to your green juice recipe.
Broccoli is rich in potassium and vitamins A, B6, and C. It also packs several antioxidants like kaempferol, which may decrease cancer growth, inflammation, and mental decline.
Often dismissed as little more than an herb and garnish for cooking, parsley is a great vegetable to use for juicing.
In one study, giving rats with diabetes parsley extract significantly decreased blood sugar and improved blood antioxidant levels, compared with a control group (28Trusted Source).
Parsley contains vitamins K, A, and C. In animal studies, it's been shown to reduce blood sugar levels, improve antioxidant status, and protect liver function.
They're also low in calories yet high in potassium, manganese, and vitamins K and C (30).
In addition, test-tube research shows that cucumber extract may help reduce inflammation in skin cells. This makes cucumber juice an excellent choice after days spent in the sun (32Trusted Source).
Cucumbers are high in potassium, manganese, and vitamins K and C. They can also help keep you hydrated and may reduce skin inflammation.
9. Swiss Chard
Swiss chard is a leafy green vegetable that is packed with key vitamins and minerals.
In a 45-day study, feeding Swiss chard extract to rats with high blood sugar reduced the elevated levels by increasing antioxidant status and altering the activity of enzymes that control insulin, a blood-sugar-regulating hormone (38Trusted Source).
You can add Swiss chard to just about any juice or use it in place of more common leafy greens, such as kale and spinach.
Swiss chard is high in vitamins A and C. Animal studies suggest that it may help reduce blood sugar levels and increase antioxidant status.
Wheatgrass is an edible grass that's often considered one of the most popular vegetables for juicing.
It's an incredibly nutrient-dense ingredient and supplies a significant amount of iron, phosphorus, magnesium, and copper, along with 17 different amino acids — the building blocks of proteins (39Trusted Source).
What's more, one study in 59 women found that supplementing with wheatgrass powder for 10 weeks significantly reduced triglyceride and cholesterol levels, improving heart health (43Trusted Source).
Wheatgrass juice can be enjoyed on its own as a shot or added to any juice for a nutritional boost.
Wheatgrass is an edible grass that contains 17 amino acids, along with iron, phosphorus, magnesium, copper, and chlorophyll. One study found that it may promote heart health by decreasing triglyceride and cholesterol levels.
Celery juice has started to gain traction in the health world — and for good reason.
Many people like to drink celery juice on its own, but it can also be combined with the juice of lemons, apples, ginger, and leafy greens for a tasty beverage.
Celery contains vitamins A, K, and C, as well as several antioxidants. Animal and test-tube studies show that celery extract may decrease inflammation and reduce blood pressure, triglycerides, and cholesterol levels.
Tomatoes are a kitchen staple and great for using in your juicer.
They're not only low in calories but also brimming with essential nutrients like vitamin C, potassium, and folate (50).
Pair tomatoes with celery, cucumber, and parsley for a refreshing, healthy juice.
Tomatoes have powerful anti-inflammatory effects and are rich in vitamin C, potassium, folate, and lycopene.
The Bottom Line
You can juice a wide variety of vegetables, each providing a unique set of nutrients and health benefits.
Try mixing and matching veggies from the list above to squeeze different vitamins, minerals, and antioxidants into your diet.
You can also combine these vegetables with fruits to further dial up the flavor and health benefits.

Using one of the world's problems to solve another is the philosophy behind a Norwegian start-up's mission to develop affordable housing from 100% recycled plastic.
Sustainable Homes<p>UN-Habitat says an <a href="https://unhabitat.org/un-habitat-aims-to-use-plastic-waste-to-support-housing-for-all" target="_blank">estimated 60% of people living in urban areas of Africa are in informal settlements</a>.

John Kerry helped bring the world into the Paris climate agreement and expanded America's reputation as a climate leader. That reputation is now in tatters, and President-elect Joe Biden is asking Kerry to rebuild it again – this time as U.S. climate envoy.
Energy Is at the Center of the Climate Challenge<p>The <a href="https://science2017.globalchange.gov/chapter/1/" target="_blank">effects of climate change</a> are already evident across the globe, from <a href="https://theconversation.com/100-degrees-in-siberia-5-ways-the-extreme-arctic-heat-wave-follows-a-disturbing-pattern-141442" target="_blank">extreme heat waves</a> to <a href="https://science2017.globalchange.gov/chapter/12/" target="_blank">sea level rise</a>. But while the challenge is daunting, there is hope. Solar and wind power have become the <a href="https://www.irena.org/publications/2020/Jun/Renewable-Power-Costs-in-2019" target="_blank">cheapest forms of power generation globally</a>, and technology progress and innovation continue apace to support a transition to clean energy.</p><p>In the U.S. under a Biden administration, long-term national climate legislation will depend on who controls the Senate, and that won't be clear until after two run-off elections in Georgia in January.</p><p>But there is no shortage of <a href="https://www.bloomberg.com/features/2020-biden-climate-change-advice/" target="_blank">ideas for ways Biden</a> could still take action even if his proposals are blocked in Congress. For example, he could use executive orders and direct government agencies to tighten regulations on greenhouse gas emissions; increase research and development in clean energy technologies; and empower states to exceed national standards, <a href="https://www.reuters.com/article/us-autos-emissions-california/defying-trump-california-locks-in-vehicle-emission-deals-with-major-automakers-idUSKCN25D2CH" target="_blank" rel="noopener noreferrer">as California did in the past with auto emission standards</a>. A focus on a just and equitable transition for communities and people affected by the decline of fossil fuels will also be key to creating a sustainable transition.</p><p>The U.S. position as the world's largest oil and gas producer and consumer creates political challenges for any administration. U.S. forays into European energy security are often treated with suspicion. Recently, France blocked <a href="https://www.wsj.com/articles/frances-engie-backs-out-of-u-s-lng-deal-11604435609" target="_blank">a multi-billion dollar contract</a> to buy U.S. liquefied natural gas because of concerns about limited emissions regulations in Texas.</p><p>Strengthening cooperation and partnerships with like-minded countries will be critical to bring about a transition to cleaner energy as well as sustainability in agriculture, forestry, water and other sectors of the global economy.</p>
Creating a Global Sustainable Transition<p>How the world recovers from COVID-19's economic damage could help drive a lasting shift in the global energy mix.</p><p>Nearly one-third of Europe's US$2 trillion economic relief package <a href="https://www.bloomberg.com/news/articles/2020-07-21/eu-approves-biggest-green-stimulus-in-history-with-572-billion-plan" target="_blank" rel="noopener noreferrer">involves investments that are also good for the climate</a>. The European Union is also strengthening its 2030 climate targets, though each country's energy and climate plans will be critical for successfully implementing them. The <a href="https://joebiden.com/clean-energy/" target="_blank" rel="noopener noreferrer">Biden plan</a> – including a $2 trillion commitment to developing sustainable energy and infrastructure – is aligned with a global energy transition, but its implementation is also uncertain.</p><p>Once Biden takes office, Kerry will be joining ongoing <a href="https://www.un.org/en/conferences/energy2021/about#:%7E:text=The%20overarching%20goal%20of%20the,2030%20Agenda%20for%20Sustainable%20Development.&text=Accelerate%20delivery%20of%20United%20Nations,related%20issues%20at%20all%20levels." target="_blank" rel="noopener noreferrer">high-level discussions on the energy transition</a> at the U.N. General Assembly and other gatherings of international leaders. With the U.S. no longer obstructing work on climate issues, the G-7 and G-20 have more potential for progress on energy and climate.</p><p>Lots of technical details still need to be worked out, including international trade frameworks and standards that can help countries lower greenhouse gas emissions enough to keep global warming in check. <a href="https://www.carbonpricingleadership.org/what" target="_blank" rel="noopener noreferrer">Carbon pricing</a> and <a href="https://www.csis.org/analysis/how-can-europe-get-carbon-border-adjustment-right" target="_blank" rel="noopener noreferrer">carbon border adjustment taxes</a>, which create incentive for companies to reduce emissions, may be part of it. A consistent and comprehensive set of national energy transition plans will also be needed.</p><p>The global shift to <a href="https://www.irena.org/publications/2019/Jan/A-New-World-The-Geopolitics-of-the-Energy-Transformation" target="_blank">clean energy will also have geopolitical implications for countries and regions</a>, and this will have a profound impact on wider international relations. Kerry, with his experience as secretary of state in the Obama administration, and Biden's plan to make the climate envoy position part of the National Security Council, may help mend these relations. In doing so, the U.S. may again join the wider community of countries willing to lead.</p>
