I just ate a few slices of lunch meat and then realized that it might have some hidden sugars in it. I ate 2 slices of gypsy salami and 2 slices of garlic salami. If I assume there are some hidden sugars in it, does it mean I've blown it today?

I also noticed that my mayonnaise (Hellmann's Real Mayonnaise) has sugar listed in its ingredients (7th on the list). The label says 0 carbs per 1 tbsp, but should I discontinue using it because of the sugar?

Thanks in advance.
