Low Sodium Subway Options For Heart Health

The lowest sodium Subway options are usually 6 inch turkey, grilled chicken or veggie subs on flatbread or multigrain with lots of vegetables, minimal cheese, and sauces like mustard or vinegar instead of salty dressings. These combinations can keep sodium under 700mg per sandwich.

How Much Sodium Is In A Typical Subway Meal?

Most 6 inch Subway sandwiches contain between 800-1500mg of sodium. For context:

Daily recommended limit: 2,300mg (general population)
Heart-healthy limit: 1,500mg (for those with hypertension)
Average 6" sub: 900-1,200mg sodium
Footlong: Double the 6" amount

A single Subway sandwich can easily provide 40-65% of your daily sodium allowance, making smart choices essential for heart health.

Lowest Sodium Breads

Bread is a significant sodium source. Here's how they rank:

Bread Type	Sodium (mg)	Notes
Flatbread	220	Lowest sodium bread
Multigrain	350	Good balance
Italian	380	Standard option
Ciabatta	410	Moderate
Italian Herbs & Cheese	580	High sodium
Wrap	580	High sodium
Gluten Free	890	Very high sodium

Best Choice: Flatbread saves 160-370mg sodium compared to other breads.

Lowest Sodium Proteins

Protein choice dramatically affects total sodium:

Protein	Sodium (mg)	Protein (g)	Best For
Rotisserie Chicken	260	17g	Best overall
Chicken Strips	210	15g	Very low sodium
Grilled Chicken	340	11g	Low sodium

Italian BMT and salami meats are extremely high in sodium
Rotisserie and grilled chicken are the safest choices
