Some believe that juicing is better than eating whole fruits and vegetables because your body can absorb the nutrients better and it gives your digestive system a rest from digesting fiber. ... Blending the edible parts of fruits and vegetables produces a drink that contains more healthy phytonutrients and fiber.

• Benefits of Vegetable Juice

Many of the most notable benefits of vegetable juice include its ability to improve nutrient uptake, protect the heart, increase hydration, prevent hair loss, detoxify the body, lower your risk of chronic disease, support skin health, increase circulation and strengthen the immune system, among others.

• Lowers Risk of Chronic Diseases

There is a significant amount of antioxidants found in many vegetables, including beta-carotene, lycopene, phytonutrients, and phenolic compounds. This can help your body fight the effects of free radicals, which include mutating healthy cells into cancerous ones. Regular consumption of vegetable juice can lower your risk of many other chronic diseases as well, including diabetes, cardiovascular disease, and even some autoimmune diseases.

• Improves Heart Health

There is a notable amount of potassium in many different juices, which can help to lower your blood pressure and relieve strain on the cardiovascular system. Furthermore, there are high quantities of iron and vitamin C, which can stimulate proper circulation and improve the amount of collagen in the body, respectively, helping to lower your risk of damaged blood vessels or arteries.

• Improves Brain Function

The search for a cure for Alzheimer’s is ongoing, but many studies have linked antioxidants to the elimination of plaque in neural pathways, and a reduced amount of beta-amyloid deposition. This can help to improve memory, concentration, and basic function, as well as slow down or even stop neurodegenerative diseases. [5]

• Increases Nutrient Intake

Some of the minerals and antioxidants in vegetable juice can cleanse the colon and re-balance the bacteria in your gut. Other nutrients are able to increase the bioavailability of certain minerals and vitamins, which can then be absorbed by the body, making your mealtimes more efficient!

• Skin Care

As mentioned, the high level of antioxidants found in vegetable juice is excellent for oxidative stress, which often occurs on the skin. Drinking vegetable juice regularly can improve the appearance of wrinkles, blemishes, scars, and age spots, while also providing relief from a number of inflammatory conditions or infections, such as psoriasis, eczema, acne, and rosacea.

• Hair Care

One of the main contributors to hair loss is some type of nutrient deficiency in the body. Given that vegetable juice is a rich source of many minerals and nutrients needed for healthy hair, such as vitamin C and beta-carotene, a glass of this juice each day can work wonders for your physical appearance. 

• Boosts Immune System

Vegetable juice is particularly well known for its high level of vitamin C; in some cases, a single glass of vegetable juice can provide your entire daily recommendation for ascorbic acid. This can give a major boost to the immune system, as vitamin C will stimulate the production of white blood cells. The immune system is further supported by the actions of other antioxidants, like lycopene, which will prevent oxidative stress and chronic disease.

• Hydrates the Body

Most vegetable juice is naturally high in water content, but some of the tougher vegetables should be mixed with water for good consistency. This means that your body will be properly hydrated throughout the day, which can help with digestion, energy levels, metabolic speed, and cognitive function.
