U.S. Is Becoming a Nation of Snackers

Experts Debate Whether Snacks Are Healthy or a Cause of Weight Gain

June 23, 2011 -- When is a snack not really a snack, but a mini-meal or even a full-on meal? And can snacking -- even serial snacking -- result in weight gain?

The answers depend on both the snacker and his or her chosen snack, according to experts speaking recently at the Institute of Food Technologists 2011 Annual Meeting and Food Expo in New Orleans.

But one thing is clear: Snacking is on its way to becoming a national pastime. Snacks, including calorie-laden beverages, comprise more than one-quarter of our daily caloric intake. Beverages, whether sugary sodas or frothy, flavored coffee drinks, make up 50% of our daily snacking calories.

We also spend a lot more time noshing on snacks today than ever before. In 2008, we snacked for about 30 minutes a day, up from 15 minutes in 2006, and we spend about 85 minutes a day drinking our snacks.

Snacks are more of an eating event or fourth meal for some, says Richard D. Mattes, PhD, a professor of food and nutrition at Purdue University in West Lafayette, Ind.

The Skinny on Snacking

“There is a lot of controversy as to whether or not snacking contributes to weight gain and how important it is as a source of useful nutrients,” Mattes says.

Part of the problem is that there is not a good definition of what constitutes a snack, he says. For example, if the first thing you put in your mouth is a granola bar at 10 a.m., is it a snack or a meal?

Mary Ellen Camire, PhD, a fellow of the Institute of Food Technologists and a professor of food science and human nutrition at the University of Maine in Orono, agrees: “One person’s snack is another person’s meal and vice versa.”

According to Mattes, snacking isn’t healthy or unhealthy.  “It is what you eat and how it fits into your daily lifestyle,” he says. “If your snacks add a lot of calories that are not offset by eating less at other times or increasing physical activity, it will cause weight gain."
