The FDA wants Americans to eat less sodium, and restaurants, foodservice operators and food manufacturers are all being urged to do their part.
Earlier this month, the U.S Food and Drug Administration issued the sodium recommendation, noting that “the targets in the final guidance seek to decrease average sodium intake from approximately 3,400 milligrams (mg) to 3,000 mg per day, about a 12% reduction, over the next 2.5 years.”
“That reduction is modest,” said Lisa Eberhart, registered dietitian and co-founder of Menu Analytics in Cary, N.C. “It will take just little tweaks on the part of chefs and food manufacturers to accomplish this and it has the potential to decrease heart attacks by 32,000 annually.”
While shaking less salt into a stock or saute can help, it’s not the total solution. “Salt is just one source of sodium,” said Eberhart. “Products like pancake and biscuit mix, chicken base, bread crumbs, cheese, barbecue sauce and marinara sauce are all problematic.”
“More than 70% of the sodium in our diets is from food products, not the salt shaker,” said Corrie Clark, registered dietitian and project manager for CIA Consulting at the Culinary Institute of America in San Antonio. She cites other culprits as well, including deli meats, salad dressings, tacos, pasta and rice dishes and soups.
A lot of suppliers are already reformulating their products to reduce sodium content. “Food manufacturers have been proactively working on this for over 10 years now, but it takes time,” said Sarah Hendren, a registered dietitian who provides nutrition and regulatory services to restaurants, retailers and food manufacturers. “Sodium does more than add flavor to a food product. Salt has a functional role in food. Beyond adding flavor, it can help improve texture, moisture retention, food safety and shelf life. A manufacturer has to make sure to retain those attributes when reducing sodium.”
Chefs, restaurateurs and foodservice operators can and should provide input into suppliers’ R&D process, working to help modify and reformulate products, the dietitians agree. But there’s a lot that can be done in the kitchen, too.
A good place to start is with the type of salt a chef or cook uses, said Clark, who is also a CIA graduate and an adjunct instructor at her alma mater.
“The sodium in salt depends on its shape,” she said. “Kosher salt is less dense than table salt so it has only 1,120 mg sodium per teaspoon rather than 2,300 mg. And sea salt has 1,870 mg per teaspoon.”
To pump up flavor with less salt, Clark recommends trying herbs, spices and yeast extract. Adding an acidic ingredient can also boost flavor.
Cheese is another higher sodium ingredient that is tweakable without jeopardizing a menu item too much. In a pasta dish or grilled vegetables, for example, top with a smaller amounts of a salty cheese so customers taste this first and are satisfied,” said Clark.
“Start with the low-hanging fruit,” advised Hendren. “Operators should assess the whole menu and identify the major culprits, then look at where it would be easiest to cut back sodium.” It may mean changing or reformulating the bread on sandwiches or using more spices and herbs in place of salt in a salad dressing, she added.
Commonsense fixes can go a long way, too. If using canned beans, drain them and rinse them “to get rid of 40% of the sodium,” said Clark. “Use sweet butter instead of salted butter, don’t salt the pasta water and drain marinades,” advised Eberhart.
To decrease sodium in a food product or menu item, Hendren suggests starting with a 10% reduction, then moving to 15% and 20%, tasting and evaluating throughout the process. She calls it “food renovation.”
“Renovating a food item can take a year or longer on its own,” she said, “then there’s consumer acceptance testing, shelf-life testing and other factors that have to be taken into consideration before that ingredient or menu item goes to market.” She thinks the 2½ years set by the FDA “is a little aggressive of a timeline,” but is confident that substantial progress will be made by the industry in the long term.
Hendren also pointed out that food manufacturers should be testing sodium and other nutrients in products every five years. “Food science technology has evolved and nutrition analysis is more refined,” she said.
Eberhart agrees. “Work with experts to re-analyze products for sodium content, as some of the methods used years ago are not as precise as what technology has made possible today. It may just be that sodium levels are lower than indicated on the label,” she said.
