Top 6 Myths: About Bottled Water
By Anndee Hochman
Bottled water — already a more than $10 billion industry — is the
fastest-growing beverage category in the U.S. But is it good for you? Here's
the pure truth.
Myth #1: BOTTLED WATER IS BETTER THAN TAP.
Not necessarily. While labels gush about bottled water that "begins as
snowflakes" or flows from "deep inside lush green volcanoes,"
between 25 and 40 percent of bottled water comes from a less exotic source:
U.S. municipal water supplies. (Bottling companies buy the water and filter it,
and some add minerals.) That's not really a bad thing: The Environmental
Protection Agency oversees municipal water quality, while the Food and Drug
Administration monitors bottled water; in some cases, EPA codes are more
Myth #2: PURIFIED WATER TASTES BETTER.
The "purest" water — distilled water with all minerals and salts
removed — tastes flat; it's the sodium, calcium, magnesium, and chlorides that
give water its flavor. The "off" taste of tap water is the chlorine; if
you refrigerate it in a container with a loose-fitting lid, the chlorine taste
will be gone overnight.
Myth #3: BOTTLED WATER WITH VITAMINS, MINERALS, OR PROTEIN IS MORE HEALTHY THAN REGULAR WATER.
"Vitamins, color, herbs, protein, and all the other additions to water —
those are a marketing ploy," says Marion Nestle, Ph.D., professor of
nutrition studies at New York University. Plus, the additives are usually a
scant serving of the vitamins you really need in a day, adds Amy Subar, Ph.D.,
a nutritionist with the National Cancer Institute. Enhanced waters usually
contain sugars and artificial flavorings to sweeten the deal and can pack more
calories than diet soda. When it comes to providing fluoride, tap water usually
wins, though that element is increasingly being added to bottled waters.
Myth #4: YOU NEED EIGHT 8-OUNCE GLASSES OF WATER EACH DAY.
The Institute of Medicine recommends about 91 ounces (a little more than 11
8-ounce glasses) of fluid daily for women. But here's the thing: It expects 80
percent of that to come from water, juice, coffee, tea, or other beverages and
the remaining 20 percent from food. That means if you drink a 12-ounce cup of
coffee and a 12-ounce can of diet soda, you only need 48 more ounces (three
16-ounce glasses, or four soda cans' worth) for the day.
