Nearly half of Americans express confidence in the safety of the U.S. food supply, a new consumer survey has revealed.

At 47%, confidence in U.S. food safety has remained stable for three years, according to the 2010 Food & Health Survey, published July 23 by the International Food Information Council Foundation.

The percent of the population “not confident” in food safety declined to 18% in 2010 compared to 24% in 2009. The study reported those consumers who said they were neutral on the topic increased to 35% in 2010 compared with 26% in 2009.

The study was the fifth annual report aiming to glean insights about consumer attitudes regarding nutrition, food safety and health-related topics.

The study said Americans’ perceptions of their health status remains steady from previous years, with 38% indicating their health is “excellent” or “very good” and 57% saying they were “extremely satisfied” or “somewhat satisfied” with their health status.

Regarding weight, the 2010 study found that Americans’ concern about their weight status was unchanged compared with a year ago, with 70% indicating they are concerned about their weight and 77% saying they are trying to lose or maintain their weight.

When asked what actions they are taking, 69% of Americans revealed they are changing the amount of food they eat and 63% said they are changing the type of food they consume, the study said.

In fact, the study found that weight loss is the top motivation for wanting to improve diets.

“Americans are more singularly focused on making dietary changes for losing weight, rather than a variety of other motivators,” the executive summary said.

The study found 64% of Americans made changes in their diet to improve health, and 65% reported the primary reason was to lose weight.
