Is making vegetable juice good for you?

Drinking vegetable juice has become an increasingly popular health trend. Proponents claim it provides a concentrated dose of vitamins, minerals, and antioxidants from fresh produce. But is juicing actually good for you? Let’s take a closer look at the potential benefits and downsides.

What is Vegetable Juicing?

Vegetable juicing involves extracting the liquid from vegetables and drinking it. A juicer breaks down veggies into a smooth, drinkable format while separating out the fibrous pulp. This allows you to consume a large quantity of vegetables easily and absorb the nutrients quickly. The most common juicing vegetables include carrots, celery, beets, kale, spinach, cucumber, and tomatoes.

Potential Benefits of Vegetable Juices

Here are some of the touted benefits of drinking vegetable juices regularly:

Increased Vegetable Intake

Juicing makes it easy to consume a wide variety of vegetables in large quantities. Just one 16 oz glass of juice can contain 2-3 pounds of produce. For those who don’t enjoy eating veggies, juicing is an effective way to increase intake and provide important nutrients.

Vitamins and Minerals

Fresh vegetable juice retains most of the vitamins and minerals from the original produce. This includes immune-supporting Vitamin C, energizing B Vitamins, bone-building Vitamin K, and vision-protecting Vitamin A. Juicing also offers antioxidants like beta-carotene.


Phytochemicals are plant compounds that provide health benefits beyond basic nutrition. Juicing helps deliver high doses of these beneficial phytochemicals, which may have anti-inflammatory, anticancer, and detoxifying properties.

Increased Energy

The natural sugars and micronutrients in vegetable juice can provide an energy boost. Juices rich in beets and carrots offer a quick shot of carbohydrates for fuel.

Improved Digestion

Some juices contain soluble fiber which can feed the good bacteria in your gut microbiome. In particular, fermentable fibers from cabbage, celery, and carrot juice may promote better digestion.

Weight Loss

Replacing higher calorie beverages like soda with vegetable juice can reduce total daily calories and potentially aid weight loss. The fiber and nutrients may also help you feel fuller.


Juicing floods your body with antioxidants which neutralize harmful free radicals and toxins. This may support liver function and help eliminate waste products from your system.

Downsides of Vegetable Juicing

Juicing veggies also comes with some drawbacks to consider:

Less Fiber

Blending and straining produces a juice with minimal insoluble fiber since the pulp is removed. This fiber helps regulate digestion, cholesterol, and blood sugar. However, some soluble fiber remains.

Lower Volume and Satiety

Chewing produce helps trigger hormones that control appetite and fullness. Drinking juice provides less volume and satiety compared to eating whole vegetables with the fiber.

Nutrient Loss

Although juicing retains most vitamins and minerals, some can be destroyed or oxidized through heat and exposure to air. Juicing also removes components like probiotics found in the veggie skins.

Sugar Spikes

The natural sugars in juice are released quickly into your bloodstream compared to eating whole produce. This can spike blood sugar levels, requiring an insulin response.

Dental Health

Fruit juices are acidic and can erode tooth enamel with excess consumption. This is less of a concern with low sugar vegetable juices.

Not a Long Term Meal Replacement

While juices can provide essential nutrients, drinking them long term is not as beneficial as eating whole vegetables. Juicing should complement a diet high in fiber-rich produce.

Oxalate Content

For those prone to kidney stones, some veggies like spinach are high in oxalates. Consuming a lot of oxalate-rich juice could potentially increase stone risk.

Who Should Avoid Juicing?

Vegetable juicing may not be appropriate for everyone. Here are some instances where juicing is not recommended:

  • Those with kidney disorders, kidney stones, gout, or rheumatoid arthritis due to the high oxalate content of some juices
  • People with diabetes or blood sugar regulation issues due to the high glycemic load
  • Anyone taking blood thinning medication due to the vitamin K content which aids clotting
  • Children under 4 years old due to potential choking hazards from inadequate chewing
  • Individuals who need to restrict sodium, potassium, or magnesium intake for medical reasons

The Best Vegetables for Juicing

You can juice most vegetables, but some provide more health advantages than others. Here are some of the top choices:

Vegetable Benefits
Carrots Beta-carotene, vitamin K, vitamin C, fiber
Celery Hydration, potassium, soluble fiber
Beets Nitrates, magnesium, antioxidants
Spinach Iron, folate, vitamin K, vitamin A
Kale Vitamin K, vitamin A, calcium, antioxidants
Cucumber Hydration, vitamin K, magnesium, silicon
Tomatoes Lycopene, potassium, vitamin C

Tips for Getting Started with Juicing

If you want to try incorporating vegetable juicing into your routine, here are some tips to get started:

  • Get a juicer that fits your lifestyle and budget. Masticating juicers are quieter and retain more nutrients.
  • Juice primarily vegetables with smaller amounts of low sugar fruits like lemons or green apples.
  • Drink juice immediately after making it to prevent oxidation and nutrient loss.
  • Store juice in an airtight container and consume within 24 hours.
  • Include a mix of leafy greens, cruciferous, root, and other veggies.
  • Juice ingredients with skins and seeds which contain beneficial fiber and nutrients.
  • Consume juice as a snack or part of a meal, not as a full meal replacement.
  • Start slowly and monitor how juicing impacts your energy, digestion, and health.

Is Vegetable Juicing Safe When Pregnant?

In moderation, juicing can be safe for pregnant women. However, here are some precautions to take:

  • Avoid unpasteurized juice products to reduce food-borne illness risk.
  • Juice only vegetables and low sugar fruits since excess sugar is linked to higher gestational diabetes risk.
  • Do not rely solely on juice for nutrition as fiber is important during pregnancy.
  • Be cautious with beet and spinach juice which may affect iron absorption and calcium levels.
  • Rinse all produce thoroughly and take extra care with food safety when juicing.
  • Consult your doctor before juicing if you have kidney issues or other medical conditions.

Overall, incorporating nutrient-dense vegetable juices can be beneficial during pregnancy when done safely. But it should not fully replace eating whole fruits and veggies.

Should Diabetics Juice Vegetables?

Juicing may be an option for diabetics in moderation if blood sugar response is considered:

  • Focus on low sugar veggies like leafy greens, cucumber, celery, and cruciferous options.
  • Avoid high glycemic veggies like carrots and beets in excess.
  • Pair juices with protein, fat, fiber to help blunt blood sugar spikes.
  • Monitor blood glucose carefully when adding juicing.
  • Stick to small 4-8 oz portions and avoid juicing fruit.
  • Consider lower sugar juicing alternatives like blending smoothies.
  • Discuss diet changes, including juicing, with your doctor.

With precautions, vegetable juicing can fit into a healthy diabetes diet by providing antioxidants without spiking blood sugar levels.

Should You Juice on an Empty Stomach?

There are arguments both for and against juicing on an empty stomach:

Potential Benefits:

  • May maximize nutrient absorption without other foods present
  • Can provide fast energy and hydration first thing
  • Some report improved digestion and alertness

Potential Drawbacks:

  • Can cause spikes and crashes in blood sugar
  • May trigger hunger and overeating later
  • Some experience GI upset like diarrhea
  • Not enough research exists on effects

Consider your own response if juicing first thing. Sipping some vegetable juice before breakfast may suit some people but not others. Pay attention to any symptoms and adjust timing if needed.


When practiced wisely alongside an overall healthy diet, juicing can be a nutritious habit that increases your vegetable intake. Focus on low sugar veggies, watch portions, and consume juice as a supplement to whole foods for maximum benefit. Juicing powerful combinations of carrots, leafy greens, celery, and more provides a boost of antioxidants, vitamins, and minerals from fresh produce straight to your cells.

However, juicing should not fully replace eating solid vegetables which provide satiety and important fiber. Those with medical conditions like diabetes or kidney issues may need to exercise particular caution with high oxalate greens or sweet roots. As with any substantial change to your diet, consult your doctor before adopting a juicing practice.

Overall, vegetable juicing can be a tasty way to flood your body with nutrients and energize your health when included as part of a nutritious, well-rounded diet.
