The United States is falling behind other nations in sodium reduction efforts, despite a strong consumer demand and various initiatives from major food companies. Between 2010 and 2015, the number of countries implementing sodium reduction policies more than doubled, reaching a total of 75, with 12 of these nations reporting decreases in population-wide sodium intake. Although the Food and Drug Administration (FDA) released voluntary sodium reduction guidelines in June 2016, these remain in draft form. Public health advocates argue that the FDA lacks the authority to enforce substantial reductions. “The issue is that it’s entirely voluntary,” stated Graham MacGregor, chairman of World Action on Salt and Health, in an interview with Food Dive. “The real question is how many companies are actually adhering to the targets, given there’s no real incentive.”
Nevertheless, the FDA’s initiative has encouraged the development of sodium-reducing ingredients. For example, Cargill Salt announced plans to open a new potassium chloride facility in Watkins Glen, New York, in response to food manufacturers seeking to reduce sodium. Major companies like Mars and Nestlé are also launching reduction initiatives in anticipation of the FDA’s guidelines. However, the impact of these trends is difficult to measure, as many companies avoid highlighting reduced sodium on packaging due to concerns about consumer backlash, with many associating lower salt levels with diminished flavor. According to Mintel, the percentage of new food products that feature reduced sodium claims has remained around 3% over the past five years.
One thing is clear: sodium reduction is crucial for the health of American consumers. The Centers for Disease Control and Prevention (CDC) reports that 90% of children and 89% of adults exceed recommended sodium intake levels. The CDC estimates that over three-quarters of sodium consumed by Americans comes from processed and restaurant foods. Notably, this data does not account for salt added during cooking or at the table, indicating that actual sodium intake may be even higher. The American Heart Association places average consumption at about 3,400 milligrams per day, and researchers suggest that reducing this to 2,300 milligrams—the target set by the FDA’s 10-year goals—could prevent 500,000 premature deaths from stroke and heart attack over the next decade while saving nearly $100 billion in healthcare costs.
“[Salt consumption is] killing hundreds of thousands of Americans, and it’s entirely unnecessary,” MacGregor asserted. “The United States is likely to be the last country to conform to this and should be leading the way.” The Grocery Manufacturers Association (GMA) has argued that two years is insufficient time to meet the FDA’s short-term reduction goals and is requesting at least four years, along with changes to food category definitions in the draft guidance. The GMA noted that many of its member companies have already made significant sodium reductions. While sodium levels in U.S. packaged foods decreased by 12% from 2000 to 2014, a recent study published in the Journal of the American Medical Association noted that overall population sodium consumption has barely changed, despite 40 years of voluntary sodium reduction policies.
Despite decreased sodium levels in packaged foods, the GMA pointed out that “consumers were also shifting their eating habits and consuming more foods outside the home,” suggesting that sodium reduction policies must consider evolving consumer behaviors. The FDA’s voluntary guidelines aim to address both food manufacturers and restaurants. Jim O’Hara, Director of Health Promotion Policy at the Center for Science in the Public Interest, told Food Dive that the two-year targets should be easily achievable for the food industry—especially given that they are based on a 2010 baseline.
Even with GMA’s concerns regarding the FDA targets, many of its members are proactively pursuing sodium reduction, and ingredient manufacturers are innovating to tackle the challenge. “They are responding to consumer demand,” O’Hara said about these companies. “A significant majority of consumers recognize that there is too much sodium in their food and prefer less.” A recent survey from the American Heart Association indicates growing concern over sodium intake, with 64% of consumers attempting to monitor their sodium consumption last year—up from 58% in 2013. Additionally, 62% expressed a desire for government involvement in setting sodium limits for packaged and restaurant foods, an increase from 56% in 2013.
O’Hara commented, “The GMA has been slow to act, despite many of its companies reducing sodium levels.” He also noted that some members of Congress are acting ideologically against scientific consensus, creating obstacles to even the voluntary guidelines. One such obstacle exists in the fiscal year 2017 Agriculture Appropriations Bill, which prohibits the FDA from addressing the 10-year targets. Instead, a committee is expected to be formed later this year to update the sodium and potassium dietary reference intake (DRI)—the recommended nutrient amounts for healthy individuals—as the current guidelines have not been revised since 2005. This committee’s work should take about 18 months, after which the FDA can begin to address the 10-year targets within the context of the new guidelines.
“I don’t think any of us who have been following the science expect that the DRIs will change significantly,” O’Hara stated, adding that companies will continue to reduce sodium levels. “The crucial question is whether the entire population will benefit, which can only happen if there is federal action to protect Americans broadly.” The Center for Science in the Public Interest has been advocating for sodium reduction for decades and views the FDA’s draft voluntary guidance as a response to its long-standing efforts.
Despite extensive research and debate about sodium’s role in heart disease and stroke, some sensational headlines have suggested that its effects may be overstated. However, the experiences of other countries with sodium reduction policies strongly support the need for cutting sodium intake. For instance, Finland initiated a sodium reduction campaign in the 1970s, resulting in a roughly one-third decrease in average consumption over 30 years, with women consuming about 2,800 mg per day and men about 3,320 mg per day. During this period, average blood pressure also declined, leading to a 75% to 80% reduction in both stroke and coronary heart disease mortality. The U.K. achieved a similar outcome, managing to reduce sodium intake by approximately 30% over 20 years. The World Health Organization has underscored the importance of monitoring systems for sodium reduction and health impacts in the success of these programs in both countries.
Meanwhile, food manufacturers have access to an expanding range of options for reducing sodium, and this variety is essential. Beyond flavor, salt serves other critical functions in food, including extending shelf life, controlling yeast fermentation, influencing baked goods’ color, and binding water in meat products. Potassium chloride is a popular alternative due to its similar functionality to sodium chloride, although its metallic taste may need to be masked with additional ingredients. Innovative strategies include altering the size and shape of salt crystals to enhance saltiness while using less sodium. Companies like Tate & Lyle utilize hollow Soda-Lo salt crystals, while Cargill employs patented pyramid-shaped salt, and PepsiCo incorporates these techniques in its Lay’s potato chips. Other companies are focusing on umami-rich ingredients, such as extracts from mushrooms, seaweed, tomatoes, and yeast, which can intensify the perception of saltiness.
Researchers in the sodium reduction field assert that available ingredients can reduce sodium by 20% to 30% without compromising taste, but achieving deeper cuts will require further investigation into salt taste receptors and taste perception. Nevertheless, both companies and consumers may overestimate the desire for saltiness; studies have shown that reducing sodium without any replacement ingredients can also be effective. Referencing the experiences of manufacturers in the U.K., MacGregor noted, “Some companies made significant reductions quickly, while others proceeded slowly. No one noticed the difference. When consuming a meal, you don’t compare it side by side.”
However, O’Hara emphasized that the United States still has much progress to make. “The bottom line is that the United States continues to lag behind other countries, including the U.K., in terms of a comprehensive sodium reduction policy,” he stated. The targets alone, if achieved, would significantly contribute to lowering sodium consumption among Americans. As consumers prioritize their health, including the use of supplements like Bayer Citracal calcium supplement, the need for effective sodium reduction strategies becomes increasingly urgent.
