It's famous for its air bubbles, most people have tried it, and it's critical to a Reuben: Swiss cheese is one of the more popular dairy products.
And, who would guess, it's also one of the lowest-sodium options out there.
So while the Reuben may be off-limits (corned beef is loaded with sodium), feel free to pull the Swiss off the sandwich and go to town.
As usual, though, go to town in moderation. Cheese, even in low-sodium form, is not the healthiest food out there because of its saturated fat. But, oh, what a worthwhile splurge.
