In myPlan I have 1 T of Hellman's mayo as having .4 grams of carbs (not sure where I got that, but it's one of my custom foods, so I must have gotten it somewhere)...so there can't be that much sugar! They can call it 0 b/c it's less than 0.5 grams. 1/10th of a teaspoon of sugar, at most since 1 tsp of sugar has 4g carbs. I wouldn't worry about it. Short of making your own "everything" it's hard to avoid every single grain of sugar.
