Consumer Reports studies flavored waters, sports drinks

NEW YORK (WABC) -- Tired of plain old water, but want to stay hydrated on a hot summer day? You might be tempted to try one of the many flavored waters and sports drinks crowding store shelves.

Consumer Reports dug in to find out if they're better for you than regular water, looking at 20 different beverages to help you decide which to sip and which to skip.

"You might be surprised at what's in this stuff," Consumer Reports Deputy Health Editor Trisha Calvo said. "Some are packed with calories, sugars, including high fructose corn syrup. And they can be pricey."

As for sports drinks, many people might turn to them to replenish electrolytes such as sodium and potassium. But some Gatorade flavors have 21 grams of sugar in each 12-ounce serving. And Powerade lists "high fructose corn syrup" as the second ingredient.

Besides, Consumer Reports says they're probably unnecessary except after intense, lengthy workouts.

Water with vitamins may sound like another smart health move, but some bottles of Vitamin Water has 32 grams of sugar.

"There's also no need to replenish vitamins just because it's hot out," Calvo said. "You don't lose vitamins when you sweat."

Plant waters are trending, with True Nopal Cactus Water claiming to "reduce inflammation." And for almost $3 a bottle, the makers of Arty Artichoke Water say artichokes "increase metabolism" and "purify toxins."

"If you do want to try any of these, you're best off ignoring the claims," Calvo said. "Just consider them a nice but pricey way to stay hydrated."

And make sure to read labels. Ingredients can vary a lot, even among drinks that seem similar.

If you're looking for something different, Consumer Reports suggests making your own infused water by slicing your favorite fruit into a pitcher of tap water and ice. It's a tasty and inexpensive alternative to bottled drinks.
