Those, counting calories to look beyond the organic label, has been advised by a U. S. researcher.

People often underestimate the number of calories in an organic snack and over-reward themselves by eating more, Brian Wansink of Cornell University in Ithaca, N. Y., says.

It was reported that Wansink and colleagues found people who ate cookies labeled as "organic" believed their snack contained 40 percent fewer calories than the same cookies without the label.

It was also found by the researchers that those most likely to do this were people who report usually buying organic foods and those who say they usually read nutritional information labels.

Study co-author Wansink says in a statement, "An organic label gives a food a 'health halo.'"

He advises those who desire a more accurate calorie count to guess and then double the number.

He further says, "You'll end up being more accurate, and you'll probably eat a lot less." (With Inputs from Agencies)
