When I'm buying bacon for us to eat in the house, like for breakfast or in a recipe, I always buy low sodium bacon. I'm not too worried about our sodium intake overall, but a few slices of bacon can be your full recommended amount of sodium for the day. And I don't want to use it all at breakfast. But when you're making these bacon-infused ground beef burgers, you are actually using the sodium in the bacon to act as the salt for the recipe. Since you're not adding additional salt, low sodium bacon isn't the best choice. If all you have in the house is low sodium bacon, you can use it (there's nothing wrong with it), but you probably want to add an extra pinch or two of salt to the recipe when you add the other seasonings.
