The voluntary guidelines call for reducing average sodium consumption by about 12% by early 2024 – from 3,400 to 3,000 milligrams per day.

Susan Mayne, a food safety expert with the Food and Drug Administration, said the change would translate to consuming roughly 60 teaspoons less salt every year.

According to the FDA, the US food safety regulator, Americans consume 50% more sodium than what is advised, and 95% of children aged two to 13 are over the recommended limit.

Such overconsumption leads to hypertension, cardiovascular disease, obesity, and diabetes.

The problem disproportionately affects racial and ethnic minorities and the Covid-19 pandemic has further amplified these health disparities, acting FDA chief Janet Woodcock told reporters.

“We know that even these modest reductions made slowly over the next few years will substantially decrease diet-related diseases,” the FDA said.

The agency will monitor how the guidelines are being implemented with the long-term goal of cutting consumption to the recommended daily intake of 2,300 mg of sodium per day for people aged 14 and over.

The FDA says the 2024 deadline gives manufacturers enough time to develop new recipes and allows consumers to change their food habits.

“Sodium is playing a role in food technology and food safety, we recognize this change won’t happen overnight,” said Woodcock. “This approach will also allow consumers’ taste to adjust.”

More than 100 countries have sodium reduction programmes and many multinational corporations are already selling food products under brands available on the US market, but made with less sodium.

“They already know how to do it,” said Mayne.
