Add pizazz to your daily diet with nutrient-rich fruit and vegetable juices.

Maybe juicing has acquired a mildly inaccurate reputation-the mere word calls forth images of sustained fasting and rigorous deprivation. But juices of late are far from spare, with indulgent offerings ranging from succulent tropical fruits to rich and tangy vegetable combinations. And for good reason: serious health devotees recognize that few foods are as nutrient-rich as fresh fruit and vegetable juices. So if you're in the habit of scrutinizing your meals, you may want to take a closer look at the beverages you're imbibing-and turn to tomato juice instead of coffee for a morning lift.

Fruit and vegetable juices provide a highly concentrated source of nutrients. By breaking down tough, fibrous plant walls, juicing extracts a number of healthful compounds, serving them up in an easy-to-digest form. And besides the better-known vitamins and minerals, fresh juices contain other, harder-to-get substances like enzymes and phytochemicals that offer a variety of specific health benefits.


For those of you who may still think that juicing is a phased-out fad of the hippie generation, consider this: modern science has recognized the value of vitamins in preventing disease, and studies have confirmed the health benefits of other nutrients. And it's not just nutritionists who are urging Americans to up their intake of fresh fruits and veggies: even the Federal government has voiced its opinion, with recommendations that set fruit and veggie consumption at five-plus servings a day.

The importance of concentrated nutrients is evident when we look at the nutritional lineup of the average American. While most of us get sufficient vitamin B to hold beri beri at bay, it's difficult to consume enough food to acquire the therapeutic doses of nutrients which have been shown to prevent disease. Juicing provides a dramatic concentration of nutrients: instead of trying to cram seven carrots into a salad, you can get the same vitamins, minerals, and phytochemicals in a single glass of carrot juice.

Vitamins extracted from plants play a major role in maintaining health, especially the antioxidant vitamins A, C, and E. In plants, vitamin A is found in the form of carotenoids. Vitamin A helps improve night vision, ensures healthy skin, and promotes the growth of bones and teeth. Vitamin C, found in citrus fruits, strawberries, tomatoes, mangoes, dark leafy greens, and other fruits and vegetables, boosts immune function, protects against blood clotting and bruising, promotes healing, and regulates adrenal gland function. Vitamin E, found in dark leafy greens and cabbage, helps repair damaged tissues and is a potent heart-healthy antioxidant.

Fruit and vegetable juices are packed with minerals as well, in a balanced and highly bioavailable form. The combination of minerals in juices boosts energy and calms nerves, maintains a healthy balance of electrolytes, and ensures the proper function of muscles,including the heart.

Freshly squeezed juices also contain enzymes, complex protein compounds produced in living cells, which speed biochemical reactions. The typical American diet centers around lots of cooked and processed foods. Since they're quickly destroyed by heat, live enzymes from raw foods are limited in most diets. Raw fruit and vegetable juices are packed with live enzymes.


Juicing itself is a relatively simple procedure. All you need are fresh, preferably organic fruits and vegetables, a good-quality juicer, and a little patience and imagination. Using organic fruits and vegetables is especially significant in juicing. If you don't, you'll be concentrating everything in the plant, including pesticides and chemicals. Additionally, if you're using organic and locally grown produce, they will have ripened to maturity on the vine, thus boosting their nutrient content.

Before you toss a handful of berries into your blender, remember that blending or pureeing isn't the same as juicing: you're getting the whole fruit, not the concentrated extraction of nutrients. Which is not to say a blended berry smoothie is a bad thing: you do get lots of fiber, and fruits like avocado and banana, which can not be juiced, can be blended and added to juiced fruits and veggies. But for the highest concentration of nutrients, extracted juices are your best bet. Juicers range in price from $90 to upwards of $1,500.

There are two basic types of high-speed juicers, centrifugal and masticating. A centrifugal juicer chops the fruit or vegetable and spins it in a basket at high speed, separating the juice from the pulp. The pulp is then ejected out the back, if the juicer has a pulp ejector. If not, you must remove the pulp yourself. A good centrifugal juicer costs between $150 and $300, and will last essentially forever. A masticating juicer mashes fruits or vegetables into a paste and then squeezes the juice through a screen in the bottom. Some masticating juicers come with a hydraulic juice press. This unique feature automatically places the pulp in a cotton bag, and hydraulically presses every last bit of juice out of the pulp. Masticating juicers tend to be more expensive than centrifugal ones.


The combination of juices you choose is limited only by your imagination. There are a few traditional rules of thumb, but these are mildly controversial. Some say it's best to avoid combining acidic citrus juices with other, more alkaline juices, since the acid/alkaline environment in the stomach is upset and can make digestion more difficult. The same applies to melons: it's said that they should be consumed separately for the best digestion. The best advice? Experiment with combinations to see what works for you.

To get the most out of your fresh juice, drink it right away. Also, the best time to drink juices is before or between, not with, meals. Any kind of liquid taken with a meal will slow the digestive process, and the high concentration of sugars in juices, can create gas and cause an upset stomach in some people. Just think of them as food, rather than beverages: they're perfect for fast breakfasts and mid-day knoshes to stave off energy slumps. Because they're so easy to digest, they're also great pre- and post-workout snacks.

You can boost the flavor and health power of your juices with quickie additions. A spoonful of ginseng extract, an ounce of wheat grass juice, or a teaspoon of concentrated green food powder will up the nutrient value and add intriguing flavors. Juice-based smoothies benefit from the addition of a little soy protein powder to add texture and nutrition. And since juicing at home may not always be an option, keep a supply on hand of organic, fresh-squeezed juices for times when you're in a rush. Get your juices from the health food store, and check the label even 'natural' juices sometimes contain lots of grape juice to add sweetness, and may offer fewer amounts of the featured fruit or vegetable.


More good news: some of the most popular fruits and vegetables used in juices contain phytochemicals that have been shown to help prevent-and even treat-specific health problems.

Citrus fruits contain limonoids, which stimulate the production of enzymes that may help prevent cancer, especially lung cancer. And grapefruit contains a type of fiber in the membranes and juice sacs that may help reduce cholesterol.

Dark, leafy greens include dandelion greens, kale, turnip greens, arugula, spinach, beet greens, mustard greens, Swiss chard, endive, collard greens, escarole, watercress, and parsley. They're rich in folic acid and may help reduce the risk of heart disease. Folic acid helps regulate blood levels of homocysteine, a naturally occurring amino acid that, at elevated levels, contributes to atherosclerosis and heart disease.

Red-orange fruits and vegetables have been celebrated of late because of their high content of carotenoids, compounds that have been shown to decrease the risk of heart disease and cancer, boost immunity, prevent cellular damage, and protect the body from a variety of age-related disorders. Fruits or veggies with a deep red, orange, or yellow hue-including carrots, red peppers, raspberries, apricots, cantaloupe, watermelon, papaya, mango, and red grapefruit-have a high content of carotenoids.

Tomatoes contain high concentrations of lycopene and other carotenoids that can help prevent colon, rectal, and stomach cancer, and may even slow the progression of already-developed cancers. Lycopene, a member of the carotenoid family that's relatively rare in foods, helps boost immunity, and may help prevent macular degeneration, the leading cause of blindness among older Americans.

Cruciferous vegetables, including cabbage, broccoflower, and bok choy, are rich in sulforaphane, indoles, and other phytochemicals that may help prevent various types of cancer, especially colon cancer. Since some of the cancer-preventive compounds in crucifers are easily lost in cooking, juicing is especially important for members of this family.


Get creative with your combinations. Experiment with the unexpected. Tomato and apple, for instance, has a wonderfully tangy and refreshing flavor, and adding a little ginger to any vegetable juice gives it an extra lift and helps combine the flavors. Try pureeing non-juiceable fruits like banana and adding them to extracted juices.
