The nation's dietitians, food makers and retailers want you to know how many calories are in that frozen pizza you devoured last night — and they don't want you to have to go looking for it.

Amid widespread concern about obesity rates, eating habits and exercise patterns, they say they'll help people make better eating choices by designating thousands of products as part of the new Smart Choices Program and adding nutritional information to the front of packages.

The labels, featuring calories per serving and number of servings, will likely be on products from food and beverage companies like Kraft Foods Inc., General Mills Inc., Coca-Cola Co. and PepsiCo Inc. starting next year, organizers say.

The goal of the program, to be unveiled Monday at the American Dietetic Association's Food and Nutrition Conference and Expo, is to get people to make smarter food choices and thus improve public health.
