A new study has found that since New York City mandated menu labels at chain restaurants over a year ago, people have consumed more, not less calories.

According to researchers, most customers, especially in low-income neighborhoods, consumed on average 20 calories more while thinking they were making better choices. However, the study reports that half of the people surveyed at least noticed the calorie count.

Nutritionist Enid Knight says the results of the study prove that people still don't understand the impact of high-calorie foods on their health.

Researchers say other studies have found that if there are healthier items available, people are more likely to make better choices.
