Can Juice Really Make You Healthier? |
Can Juice Really Make You Healthier?
You may
have dismissed it as just another food fad, but experts are putting
a whole new spin on the beverage. Read on, then start sipping.
On most days, you do everything you can to work more fruits and
vegetables into your diet: You add berries to your oatmeal, pile
spinach on your pizza, and swap out your fries for a side salad.
While you should be congratulated for your efforts, chances are you,
like more than 70 percent of adults, aren’t hitting the USDA target
of nine servings of produce (that’s four half-cup servings of fruit
and five half-cup servings of vegetables) daily
That’s where juice comes in. “It can be overwhelming for busy women
to try to get the fruits and vegetables they need,” says Kathy
McManus, R.D., director of the department of nutrition at Brigham
and Women’s Hospital in Boston. “Drinking 12 ounces a day can be a
convenient way to get two servings closer to your produce goal.”
Juice also can boost your health, as the
nutrients normally found in these beverages have been credited with
everything from warding off cancer to preventing age-related
ailments. A recent study published in
The American Journal of Medicine
concluded that people who drank three-plus servings per week of
juices high in polyphenols—antioxidants found in purple grape,
grapefruit, cranberry, and apple juice—had a 76 percent lower risk
of developing Alzheimer’s disease. Plus, some store-bought juices
are actually higher in certain nutrients than the fruits and
vegetables they came from (see the boxes in this story for
specifics).
The key, according to McManus, is to make juice a supplement to
rather than a substitute for all of the fruits and vegetables in
your daily diet. Though these beverages are generally higher in
sugar and calories and lower in fiber than their whole counterparts,
research shows that a combination of the two may be the most
beneficial to your overall health. The Harvard-based Nurses’ Health
Study found that adults who had the highest intake of produce in
both solid and liquid form— about eight servings per day—were 30
percent less likely to have a heart attack or stroke than those who
got 1.5 or fewer servings daily. Plus, their overall risk for any
type of chronic disease was 12 percent lower than the fruit and
veggie skimpers’. To squeeze more nutrients out of every single sip,
follow this expert advice.
Mix It Up
A glass of OJ may deliver all the vitamin C you need in a day, but
make room in your fridge for a new variety or an exotic blend and
you’ll get an even healthier payoff. That’s because drinking a
range of juices helps you maximize the kinds of vitamins and
minerals you’re getting.
“Individual fruits and vegetables can offer
some measure of protection against illness and chronic disease,”
says Janet Novotny, Ph.D., a research physiologist at the USDA’s
Beltsville Human Nutrition Research Center in Maryland. “But to get
the greatest preventative benefits, you should diversify the type
and color of produce you’re taking in.” In a study published in
The Journal of Nutrition,
women who ate from the widest array of botanical groups (18 plant
families versus 5) experienced the most protection against oxidative
damage, or the breakdown of cells and tissues. Switch from white
grapefruit juice to a ruby red version (the darker fruit may be more
effective at cutting cholesterol), or try a blend with açaí, an
antioxidant-rich Brazilian berry.
Learn The Lingo
Some store-bought juice “drinks,” also called “cocktails” or
“punches,” contain as little as five percent juice. What you will
find: water, lots of sugar, and artificial flavoring. Check the
label to see what you’re getting. “Your beverage should be 100
percent fruit juice, made without added sugar or high-fructose corn
syrup,” says Felicia Stoler, R.D., a Holmdel, New Jersey,
nutritionist.
“But extra vitamins, minerals, and fiber can be a healthy bonus.”
Stick to a Two Drink Maximum
While the disease-fighting potential of juice
may be considerable, it shouldn’t be an invitation to keep refilling
your glass. “Most fruit juices are not only higher in calories and
natural sugars—up to 38 grams per 8-ounce glass—but also take less
time to consume than the whole fruit,” says Stoler. There’s no
peeling or slicing involved, and unlike whole foods, the energy in
beverages won’t do much to fill you up—which could spell weight gain
if you’re not careful. One study published in the
International Journal of Obesity
found that when people were given either the solid or liquid version
of certain foods (watermelon versus watermelon juice, cheese versus
milk, and coconut meat versus coconut milk), those who drank the
liquids consumed up to 20 percent more calories throughout the rest
of the day. “Most juices are low in fiber, a nutrient that helps
delay the emptying of your stomach,” says Stoler. “And unlike whole
fruits and vegetables,
which take time to be broken down by the body, juice moves through
your system almost as quickly as water.” To make juice a
waistline-friendly part of your diet, she recommends limiting your
intake to no more than 200 calories per day. That’s 16 ounces of
most fruit varieties (like apple, orange, and grapefruit), about 8
to 12 ounces for more sugary juices (like grape and pomegranate),
and 24 ounces of most vegetable juices.
Don’t Bother With Juice Fasts
You might have heard that this extreme diet—consuming nothing but
juice for days or weeks on end—can help you slim down or “cleanse”
your body of harmful toxins, but McManus warns not to buy into the
hype. “There’s simply no scientific evidence to prove that
subsisting on juice helps expel waste products from your system,”
she says. “You’ll just be denying your body essential nutrients from
the foods that you’re not eating, like lean proteins, healthy fats,
and whole grains.”
Because you’re getting so few calories (often less than 1,000 per
day), you may feel sluggish, dizzy, or irritable—not to mention
hungry. Some people even report bad breath, breakouts, and sinus
congestion. Even if you can put up with all that, you probably won’t
experience lasting weight loss. “You may drop a few pounds,” adds
McManus “But they’ll return once you start eating real food again.”
Get Fresh
One of the most effective strategies to
control calories, maximize variety, and increase the nutritional
value in every glass is to create your own fresh blend at home.
That’s because you can hand select the kinds of fruits and veggies
(which nearly always contain fewer calories) you’re using. And if
prep time has held you back from snacking on produce, juicing
literally lets you cut corners: Most items can be popped whole in
your juicer (rind, skins, and all) or cut into large pieces to fit
the feeder tube. While there are three types of juicers—masticating,
triturating, and centrifugal—the latter is the easiest to use and
the most affordable. Usually priced between $100 and $200, “the
centrifugal type works by first grating or finely chopping the
produce, then spinning it at a high rpm [revolutions per minute] to
push the pulp against a straining screen,” says Cherie Calbom,
author of Juicing for Life.
“When shopping around, look for a model with 600 to 1,000 watts of
power and removable parts that can go in the dishwasher.”
Need more guidance? After putting several
popular extractors through their paces, these three earned the
highest overall marks for speed, ease of use, and quick cleanup.
Best value: Juiceman Junior Model JM400
($70; at Wal-Mart)Built
to run at two speeds, this chrome-plated extractor is stylish enough
to display on your countertop between uses.
Easiest cleanup: Breville Juice Fountain
Compact
($100;
brevilleusa.com)This
streamlined model takes up less counter space than other juicers out
there and was designed with removable, dishwasher-safe parts. Extras
like a splash-proof lid and shock-resistant plug make this extractor
as smart as it is compact.
Ideal for big families: Jack LaLanne Power
Juicer Pro
($150;
powerjuicer.com)Thanks
to its ample size and huge feed tube, you’ll do very little chopping
before adding fruits and vegetables to this stainless steel
extractor. A straining element allows you to reserve the fiber-rich
pulp to use in soups, salsas, muffins, and other recipes.
Experiment with a Lot of Ingredients
You can increase the variety of nutrients you’re
getting while cutting the total sugar content by tossing at least
one vegetable into your blend. “Red and yellow peppers are chock
full of carotenoids, while cucumbers can add potassium,” says Calbom.
“And if you’re feeling adventurous, feel free to toss in some
spinach leaves or beet greens, which are both good sources of iron.”
Pears, green apples, and berries all have high water content, so
they sweeten the flavor of your drink without spiking the calorie
content. Calbom recommends washing your fruits and vegetables before
tossing them into the juicer to remove any dirt, mold, or surface
pesticides.
