So let’s dive in and see how to build a low sodium Subway meal.

Who Needs Low Sodium at Subway?

A low sodium diet is less than 2,300 mg of sodium per day. The American Heart Association recommends even lower for those that are at risk for other complications to 1,500 mg per day especially for those that have high blood pressure.

Excess sodium in the diet increases blood pressure, causes fluid retention, and increases your risk of heart disease and stroke. 

According to the Dietary Guidelines for Americans 2020-2025, the average American consumes 3,393mg of sodium per day. 

The following foods commonly consumed foods high in sodium are:

  • Sandwiches
  • Deli meats
  • Cheeses
  • Burgers
  • Tacos
  • Pizza
  • Rice and pasta dishes
  • Soups 
  • Bread

As you can see, sandwiches, deli meats, cheese, and breads are major contributors to high sodium intake. This can make it pretty tricky to eat low sodium at Subway.

What Is a Low Sodium Meal?

A low sodium meal will have 500-700 mg of sodium if we are aiming for no more than 2,300 mg of sodium per day and are eating 3 meals a day for instance.

So this leaves room for 1-2 low sodium snacks ranging from 150-200 mg.

Keeping these guidelines in mind let’s build our low sodium subway meal.
