The Food and Drug Administration has finalized a rule that lets food makers swap part of the salt in many everyday products for a salt substitute. The change covers 139 foods that have a federal “standard of identity,” and it starts December 14, 2026.
For shoppers, it could mean more bread, cheese, canned vegetables and mayonnaise with less sodium on the label. The rule only opens the door, and it is up to each manufacturer whether to walk through it.
What the FDA changed on December 14
A standard of identity is a federal recipe that says what a food must contain to carry a name like “mayonnaise” or “cheddar cheese.” Until now, 139 of those recipes allowed or required salt but did not permit salt substitutes, which boxed manufacturers in when they wanted to cut sodium.
The final rule appeared in the Federal Register on October 13, 2026, and states that it is effective December 14, 2026. It adds a definition of “salt substitute” to the FDA’s regulations and amends 139 of the recipes, 80 of them directly and 59 through existing cross-references.
The rule does not name a single approved ingredient. It allows any “safe and suitable” salt substitute or combination, with potassium chloride the best-known example. Yeast extracts, amino acids and dairy extracts are among the other possibilities.
Which foods could taste and read differently
The foods named in the rule text include bread, rolls and buns, many cheeses, canned corn, canned tuna, self-rising flour and mayonnaise. Oysters and frozen breaded shrimp were not amended, so they stay as they are.
People watching sodium for blood pressure are the ones with the most at stake. The rule cites the Dietary Guidelines figure of less than 2,300 milligrams of sodium a day for people 14 and older, and it says cutting sodium may help lower the risk of hypertension, a major risk factor for heart disease and stroke. Anyone on a low-sodium diet who buys these staples every week should read the label on each new version rather than assume it is lower in sodium.

The gap between the limit and real life is wide. The FDA says average sodium intake in the U.S. is approximately 3,400 milligrams a day, and that more than 70 percent of it comes from processed, packaged and prepared foods, the kind of products this rule reaches.
Nothing in the rule forces a recipe change. It lists voluntary reformulation and relabeling as possible costs for companies that choose to use a substitute, and it states that there are no regulatory costs. The earliest changes shoppers might notice are reformulated store brands and national brands that decide to market lower-sodium versions after December 14.
How a substitute shows up on the label
The rule sets no new labeling requirements for ingredients that replace salt. Existing rules still apply, so an ingredient must be declared by its common or usual name. Potassium chloride has to appear as “potassium chloride” or “potassium salt,” and major allergens still have to be declared.
That puts the answer in the ingredient list, not on the front of the package. Under the FDA’s food labeling rules, labeling is required for most prepared foods, so the label is where a shopper can see what a recipe now contains.
A shopper comparing two loaves or two cheeses can check the sodium line on each and look for potassium chloride or potassium salt in the ingredients. Anyone on a medication or a diet that limits potassium as well as sodium can ask a doctor or dietitian what suits that situation before switching products.
Who can still object, and to what
The comment period is over, but one narrow window is open. People who want to challenge the changes to the dairy standards, which sit in parts 131 and 133 of the federal food regulations, have until November 12, 2026 to submit objections or requests for a hearing. That deadline covers the dairy standards only, not the rest of the 139.
The same notice names Andrew Yeung and Rumana Yasmeen of the FDA’s Office of Nutrition and Food Labeling as contacts for questions about the rule, at 240-402-2371. Most households will never file an objection, but the date shows how firm the other deadline is: the substitutes become allowed on December 14 whether or not anyone objects to the dairy pieces.
The changes run across 16 parts of the federal food regulations, including the dairy rules in parts 131 and 133 and the standards for the bread, canned corn, canned tuna and flour named above, all filed under FDA docket number FDA-2022-N-2226. A shopper does not need to track any of that to benefit. The practical effect arrives on shelves, one reformulated product at a time, if and when companies decide to use the new room.
What this means for a grocery budget
The rule is not a price change, and the FDA reports no regulatory cost from it. It does show how much of a household’s food spending sits in the standardized staples covered here: bread, cheese, canned goods and spreads.
For people on a fixed income, the practical question has two halves. One is whether a lower-sodium version of a favorite staple will show up on the shelf. The other is whether the grocery bill itself is as low as it could be, since several benefit programs help with food and household costs and must be applied for rather than arriving on their own.
On a fixed grocery budget as labels change?
The sodium rule settles what may go into a loaf of bread. It says nothing about what the loaf costs, and many retirees miss food and bill help they could apply for because no letter ever arrives.
The turn from the label to the budget is plain: a household watching both sodium and spending is the household that benefits from a scan of programs it may have overlooked. The Benefits Checklist covers 11 benefit programs, including SNAP food benefits at 60 and older, heating and cooling help and property tax breaks, and it lists the 2026 income limits for each so the comparison takes minutes. A printable tracker comes with it, along with a 50-state phone directory.
