Is Significant Sodium Reduction Achievable? RELEASED AT THE 2011 IFT ANNUAL MEETING & FOOD EXPO

June 14, 2011

NEW ORLEANS – Food manufacturers face a tremendous challenge in lowering the amount of salt in foods while maintaining taste and consumer loyalty, according to symposium panelists at the 2011 Institute of Food Technologists (IFT) Annual Meeting & Food Expo®.

While humans crave and need salt intake, current consumption is far ahead of what is needed, said Russell Keast, Ph.D., associate professor at the Center for Physical Activity and Nutrition at Deakin University in Australia. While Americans require only 2.5 grams of salt each day, they consume, on average, 9.5 grams primarily from processed and restaurant foods.

Too much salt consumption has been linked to hypertension, high blood pressure and cardiovascular disease.  Fifty percent of consumers intend to decrease salt intake, but most don’t want to sacrifice taste, said Janice Johnson, Ph.D., of the Salt Division at Cargill, Inc.

The 2010 Dietary Guidelines for America recommend that daily salt intake be dropped to 2,300 milligrams or about one teaspoon each day. Keast said that significant sodium reduction in food products may not be possible without government enforcement, as manufacturers that maintain high salt levels will continue to have an unfair advantage with consumers.

“Taste is the number one driver of food purchasing decisions,” said John E. Hayes, Ph.D., assistant professor of food science and director of the Sensory Evaluation Center at Pennsylvania State University. Salt not only enhances food flavor, but also dulls the bitter taste in many foods.

“Salts block bitterness which is why we like it,” said Hayes.

Johnson also said that salt is an important preservative that inhibits microbial growth in foods, lowers water activity and preserves flavor in foods.

Chris Loss, Ph.D., of the Department of Menu Research and Development at the Culinary Institute of America (CIA), said chefs are beginning to experiment with the use of other spices and ingredients to enhance flavor, and/or “distract the palate” from lower amounts of salt.  Sea salt, which has more than 30 percent less sodium, is also a viable alternative.

Any long-term solution “will be dependent on desired attributes – taste, texture, food safety; the type of food product; and cost,” said Johnson.
