Healthy Soft Drinks an Oxymoron? (cont.)
"Zero-calorie" sodas are aimed at consumers who don't like the idea of a "diet" drink. Jazzed-up flavors like pomegranate, cherry, vanilla, lemon, lime, and caramel are also making their way into soft drinks.
How Healthy Are the New Soft Drinks?
The truth is that artificially sweetened soft drinks - even those fortified with vitamins and minerals -- are anything but natural and healthy, says Marion Nestle, New York University nutrition professor and author of What to Eat.
"It is ridiculous to market soft drinks as healthy, but in today's marketplace consumers are demanding more healthy looking food, and beverages and soft drink manufacturers need to boost sales," she says.
Most consumers do not need the extra vitamins found in fortified soft drinks, she adds.
"We are not vitamin deficient, and these beverages do not address the real health issues of our country of obesity, heart disease, or cancer," says Nestle.
University of Vermont researcher Rachel Johnson, PhD, RD, agrees.
"It concerns me that we have so many ultra-fortified products where we virtually put a vitamin pill into a soft drink," she says. "The nutrients put into these soft drinks are not the shortfall nutrients that are lacking in our diets such as calcium, potassium, folate, or vitamin D."
Johnson advises consumers to choose beverages that not only quench thirst but also deliver needed nutrients, such as 100% fruit juice and skim or low-fat milk.
"These beverages will help you meet your nutritional needs and satisfy the recommendations of the [U.S. government's] 2005 Dietary Guidelines," she says.
Diet Soft Drinks vs. Regular
Consumers are turning away from sugary sodas because of the potential link to obesity. Yet "there is very little evidence that diet sodas help people lose weight," says Nestle. "In fact, one study suggested that people use diet drinks to help justify eating more calories."
Experts do agree that low- or no-calorie soft drinks are better than sugary regular sodas.
"It is fine to enjoy a diet soda as long as you don't use them as a license to add more calories from other foods. Because some people drink a diet drink so they can eat a big piece of cake," says Nestle.
Diet soft drinks are also helpful for consumers who are hooked on regular sodas and trying to wean themselves off the sugary beverages.
Liquid Calories Add Up Quickly
Liquid calories can lead to weight gain because beverages go down so easily. They may satisfy thirst, but they don't affect hunger. So people who drink sugary sodas don't generally take in fewer calories from food to compensate.
"Lots of people don't think about what they are drinking and how it impacts the overall diet," says Johnson. "The average American gets 22% of their calories from beverages."
