Buyer Beware: The next time you're in the grocery store, don't be fooled by what's written on the front of the package.

The Food and Drug Administration is warning that many shoppers are being tricked into thinking certain foods are healthier for them than they really are because of misleadling labels.

Most shoppers want to buy the healthiest food possible, but the FDA is now calling out some food manufacturers for misleading claims on the front of the package.

CBN News Reporter Lorie Johnson spoke more about what to look out for on food labels on Thursday's Newswatch program. Click play for more, following this report.

"The companies try to get around the rules by using vague terminology such as 'Helps supports your immune sytem' or 'Heart healthy,'" Bruce Silverglade, with the Center for Science in the Public Interest, said. "These claims are not reviewed by the FDA and are confusing to consumers."

Offenses include such things as implying blended juice products are made from a single juice, claims that a product is free of trans fats when it is high in saturated fats, or nutrient claims on foods for children that are only approved for adults.

"I'm sure they're doing whatever they think will sell the product," one shopper said.

The FDA is slapping 17 companies with a warning to change their labels or risk being pulled from the store shelves. They're giving the companies two weeks to respond.

"We hope this is the start of a battle that will lead to a war that will end deceptive food labeling," Silverglade said.

Although shoppers should beware of what's written on the front of packages, they can still trust what's on the nutrition facts box on the back or side of the package, and the list of ingredients.
