Reducing sodium in the American diet is no small feat, but it’s necessary. With the prevalence of heart disease, type 2 diabetes, and obesity increasing, the US is facing a health crisis related to diet.
The FDA has taken a phased approach to cutting sodium levels in processed and prepared foods, aiming to give consumers healthier choices [1]. Let’s take a closer look at the progress made so far and what it means for the future of our food supply.
Sodium is good for health, but excessive intake can lead to serious health problems. High sodium intake is associated with elevated blood pressure, a primary risk factor for heart disease and stroke.
Considering that more than 70% of the sodium consumed in the US comes from processed and prepared foods, reducing sodium levels in these products can significantly impact public health [1].
FDA’s sodium reduction targets
In 2021, the FDA set voluntary sodium reduction targets, aiming to reduce average sodium consumption from 3,400 mg per day to 3,000 mg per day over 2.5 years.
These targets, known as Phase I, are designed to encourage the food industry to lower sodium levels in their products gradually.
The ultimate goal is to reduce sodium intake to about 2,750 mg per day, moving closer to the recommended upper limit of 2,300 mg per day for people 14 years and older.
In August 2024, the FDA introduced a draft guidance with new, more ambitious targets for the next phase of sodium reduction. These Phase II targets build on the progress made in Phase I and aim to continue the downward trend in sodium levels across the food supply [1].
Progress so far
The FDA’s preliminary assessment of progress toward the Phase I targets, using data from 2022, shows promising results. According to the FDA’s report, 40% of food categories had already achieved the Phase I sodium targets or were within 10% of meeting them.
Among the overarching food categories analyzed, 11 out of 16 saw sodium reductions in at least 50% of their subcategories. Packaged food categories, in particular, have shown significant progress, with many manufacturers lowering sodium levels ahead of the targets [1].
One standout category is toddler and baby food, where manufacturers have exceeded the Phase I targets, achieving reductions beyond what was initially expected.
This is a positive sign that some food industry sectors are taking sodium reduction seriously and acting ahead of schedule.
Packaged vs. restaurant foods
The progress in sodium reduction varies between packaged foods and restaurant foods. More than 60% of packaged food categories have decreased in sodium, with 30% of these showing reductions of more than 10%. However, 25% of packaged food categories have seen increased sodium levels, while 13% have shown no change.
In contrast, the restaurant food sector has been making slower progress. While 35% of restaurant food categories have decreased in sodium, nearly half (49%) have increased their sodium content, and 16% have shown no change.
These differences highlight the challenges in achieving widespread sodium reduction across all food industry sectors. Restaurants may face difficulties sourcing ingredients with reduced sodium content, which could explain the slower progress in this sector [1].
Food categories with notable changes
Some food categories have seen more significant changes in sodium content than others. The data shows a range of outcomes across different types of foods [1]:
- Toddler/baby food – 100% of this category has seen a decrease in sodium, a notable achievement.
- Dairy and cereals – Both categories have seen reductions in 67% of their subcategories.
- Meat and poultry – 64% of this category has decreased in sodium, but 32% have seen an increase.
- Snacks, fats, oils, and dressings – Both categories have seen reductions in 64% and 60% of their subcategories, respectively.
On the other hand, categories like Mixed Ingredient Dishes and Sandwiches have seen increases in sodium content in more than half of their subcategories, indicating areas where more effort is needed.
What’s next?
While the progress so far is encouraging, there’s still work to be done. The FDA plans to continue monitoring sodium levels in the food supply and will conduct a formal evaluation once the 2024 data becomes available.
This will provide a clearer picture of how close we are to meeting the Phase I targets and what further steps are needed to achieve the Phase II goals.
The FDA’s phased approach to sodium reduction reflects a commitment to improving public health through gradual, achievable changes.
Even modest reductions in sodium consumption can significantly reduce the chronic disease risks related to diet.
